Substitute Part Grouping Explanation

Substitution of the BJ301-02-Y-A is based on strict electrical and mechanical compatibility across the following critical parameters:

  • Connector Configuration: 2-position plug, board-to-board style
  • Pitch Specification: 0.157" (4.00mm) center-to-center spacing
  • Mounting Method: Surface mount, right-angle orientation
  • Electrical Ratings: 300V voltage rating and 3A current capacity
  • Termination Type: Solder attachment to PCB
  • Operating Environment: -55°C to 105°C temperature range
  • Contact Finish: Tin plating for solderability and corrosion resistance
  • Moisture Sensitivity: MSL 1 classification

The substitute part 02P-LEBSS-TF from JST Sales America Inc. meets all these critical parameters, enabling direct functional replacement in applications where the BJ301-02-Y-A was originally specified.

Engineering Selection Recommendations

The 02P-LEBSS-TF from JST Sales America Inc. is the qualified substitute for the obsolete BJ301-02-Y-A. Both connectors share identical electrical ratings, mechanical dimensions, and operating specifications, ensuring functional interchangeability in board-to-board SSL applications.

Product Status Consideration: The BJ301-02-Y-A is obsolete with limited inventory availability (1004 pcs). The 02P-LEBSS-TF is active production with higher inventory levels (2897 pcs), providing superior long-term supply chain security.

Compliance Consideration: The BJ301-02-Y-A carries ROHS3 compliance certification. The 02P-LEBSS-TF is RoHS non-compliant. Design teams must evaluate regulatory requirements for their end application. If RoHS3 compliance is mandatory, alternative sources or design modifications may be necessary.

Packaging Consideration: The 02P-LEBSS-TF is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Confirm packaging compatibility with your manufacturing workflow.

Frequently Asked Questions (FAQ)

Q: Can the 02P-LEBSS-TF directly replace the BJ301-02-Y-A in existing designs?

A: Yes. Both connectors are 2-position, 4.00mm pitch, surface mount, right-angle plugs with solder termination. Electrical ratings (300V, 3A) and operating temperature range (-55°C to 105°C) are identical. Physical dimensions and mating interfaces are compatible for direct PCB layout substitution.

Q: What is the difference in housing material between these connectors?

A: The BJ301-02-Y-A uses Liquid Crystal Polymer (LCP), while the 02P-LEBSS-TF uses Polyamide (PA9T), Nylon 9T. Both materials provide adequate mechanical strength and thermal stability across the specified operating range. Material selection does not affect electrical performance or mating compatibility.

Q: Why does the 02P-LEBSS-TF show RoHS non-compliance while the BJ301-02-Y-A is ROHS3 compliant?

A: RoHS compliance status reflects the manufacturing date and material composition at the time of production. The 02P-LEBSS-TF may have been manufactured under different material specifications. Verify RoHS requirements for your specific application and regulatory jurisdiction before finalizing component selection.

Q: Are there any differences in contact material that affect performance?

A: The BJ301-02-Y-A uses Phosphor Bronze contacts, while the 02P-LEBSS-TF uses Copper Alloy contacts. Both materials are tin-plated and provide equivalent electrical conductivity, corrosion resistance, and solderability for this connector class. Contact material does not impact functional interchangeability.

Q: What packaging format is the 02P-LEBSS-TF supplied in?

A: The 02P-LEBSS-TF is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. Confirm your manufacturing equipment supports this packaging format. The BJ301-02-Y-A packaging format is not specified in available data.

Q: How do I verify mechanical fit before committing to a design change?

A: Both connectors share identical pitch (4.00mm), mounting type (surface mount, right angle), and termination method (solder). PCB footprints and mating interface dimensions are compatible. Physical samples should be evaluated against your specific PCB layout and mating connector to confirm clearance and alignment.
