JST Sales America Inc. B02B-PASK-1

Product summary B02B-PASK-1 JST Sales America Inc. VERTICAL HEADER CONNECTOR, 2 POSITIONS, 2MM

The JST Sales America B02B-PASK-1 is a vertical header connector featuring 2 positions with a compact pitch of 2.00mm, designed for through-hole PCB mounting. As part of the PA connector family, the B02B-PASK-1 targets wire-to-board applications requiring secure mechanical locking and reliability in circuit connectivity. Its vertical configuration and 2-pin layout lend it to a wide variety of control boards, sensor interfaces, and signal transmission modules, where space constraints and secure retention are critical. Engineering teams benefit from its well-documented design standards and placement flexibility, supporting streamlined integration into modern electronic designs.

Main characteristics and mechanical structure of B02B-PASK-1 and the PA series connectors

B02B-PASK-1 belongs to JST’s PA family, which is engineered to support wire-to-board (crimp style, insulation displacement connection/IDC style) and wire-to-wire connections. Among its hallmark features are the secure locking device, an insertion guide mechanism, and highly reliable contact points. These design elements minimize wiring errors and ensure physical and electrical integrity even under vibration or mechanical stress. Compared with prior-generation 2.0mm pitch connectors, the PA line introduces retainer mountable types and secondary retainers, providing advanced options for complex harnesses, strain relief, and flexible engineering configurations. The connector’s flanged press pin and compatibility with both crimp and IDC sockets further expand application scenarios, from compact sensor boards to multi-wire harness assemblies in automation equipment.

Electrical properties of B02B-PASK-1 as well as PA, PAF, and PAL connectors

Engineers selecting B02B-PASK-1 or devising interconnect systems with PA family connectors will find a robust electrical specification matrix. The standard PA header type supports 3A AC/DC (with AWG #22 wire) and is rated for up to 250V AC/DC, with a high insulation resistance (minimum 1,000 MΩ initially) and a low contact resistance (maximum 10 mΩ initially). Operating temperatures span from -25°C to +85°C (inclusive of current-induced temperature rise), ensuring suitability for industrial or instrumentation environments. For configurations requiring strain relief or insulation displacement, PAF connectors are rated at 1A/100V AC/DC (AWG #26), while PAL connectors extend the wire-to-wire range with a similar current and voltage profile, adding options for panel thickness from 0.5 to 2.0mm. With safety and performance standards such as E60389 recognition and RoHS2 compliance, design teams can ensure regulatory alignment in their product lifecycle.

Material choices and regulatory compliance for B02B-PASK-1 JST Sales America Inc. VERTICAL HEADER CONNECTOR, 2 POSITIONS, 2MM

Material choices in the B02B-PASK-1 and its family are dictated by both electrical performance and industry compliance requirements. Contacts utilize phosphor bronze with tin-plated reflow treatment, optimizing both conductivity and oxidation resistance. Housings are molded from PA66 or glass-filled PBT, both flammability-rated to UL94V-0 and available in natural (white) or ivory colors depending on the header type. All components are RoHS2 compliant, facilitating deployment in global and environmentally-sensitive market segments. The presence of retainer options and the use of metallic strain relief (in PAF types) reflect a design approach prioritizing safety and installation robustness. Copper alloy posts and solder tabs further reinforce mechanical stability and ease of soldering in automated assembly environments.

Installation methods and PCB design guidelines for B02B-PASK-1 JST Sales America Inc. VERTICAL HEADER CONNECTOR, 2 POSITIONS, 2MM

An essential consideration for procurement and engineering selection is the variety of mounting options available in the B02B-PASK-1 series. Configurations encompass top entry, side entry, bottom type, bottom type with extended length, and high box variants. The standard through-hole header is optimized for a PCB thickness of 1.6mm and is subject to precise layout tolerances (±0.05mm for all centers) to guarantee alignment and secure retention during automated placement. Additionally, SMT types are available for surface-mount applications where high-density or reworkability is critical. Engineers are advised to consult JST's detailed assembly layouts to ensure compatibility with piercing methods and board designs. The robust mechanical retention and the flexibility between vertical and horizontal orientations make B02B-PASK-1 suitable for modular subassemblies and integration into standard and custom PCB form factors.

Part number classification and configuration selections within the B02B-PASK-1 JST Sales America Inc. VERTICAL HEADER CONNECTOR, 2 POSITIONS, 2MM product range

Within the B02B-PASK-1 series, JST provides a systematic model numbering system that facilitates rapid identification and specification matching. This system covers form factors (top/side/bottom entry), circuit count (from 2 up to 16 positions, depending on variant), housing color, resin material, type of clinch or pin style, and multi-circuit options for harness designs. Configuration options also include strip or loose piece packaging for contacts, different flammability grades, and retainer mountable versions, each targeted to specific harnessing or interface needs. Design engineers can select from color-coding, mounting features (bossed/non-bossed), and panel lock options to ensure functional and aesthetic match with the end design. This allocation system assists procurement professionals in specifying the correct parts and facilitates cross-referencing for larger system builds.

Possible alternative or substitute models for B02B-PASK-1 JST Sales America Inc. VERTICAL HEADER CONNECTOR, 2 POSITIONS, 2MM

When evaluating the B02B-PASK-1 JST Sales America Inc. CONN HEADER VERT 2POS 2MM, it is important to consider the full PA family ecosystem, including PAF (IDC style) and PAL (wire-to-wire crimp style) connectors. The family’s high modularity allows direct interchange between crimp and IDC sockets, broadening compatibility with pre-existing wire harnesses or PCB layouts. Equivalent models within the PA range may differ in current rating, mounting style, or retainer configuration but maintain the core 2.0mm pitch and locking mechanisms. Engineers looking to replace or expand existing systems should also consider harness variations and the availability of secondary retainers, ensuring continued reliability and regulatory conformity. Consultation with JST technical support is advised when transitioning between PA, PAF, and PAL connectors in mission-critical applications.
