Engineering Selection Recommendations

Primary Recommendation: 68604-136HLF

The 68604-136HLF is the direct active equivalent from Amphenol ICC. It maintains identical electrical and mechanical specifications to the obsolete 68604-136 while offering active product status, RoHS compliance, and documented operating temperature range (-65°C ~ 125°C) with 3A current rating. This part provides the highest compatibility for direct replacement in existing designs.

Secondary Recommendations:

PBC36SFAN and PEC36SFAN (Sullins Connector Solutions)

Both Sullins parts provide board-to-board or cable interface flexibility with identical 36-position, 2.54mm pitch configuration. PBC36SFAN features gold mating contacts matching the original specification, while PEC36SFAN uses tin finish. Both support -65°C ~ 125°C operating temperature and 3A current rating with ROHS3 compliance. The breakaway capability offers design flexibility not present in the original part.

PEC36SFCN (Sullins Connector Solutions)

This variant extends the post length to 0.320" (8.13mm) compared to standard 0.120" (3.05mm), accommodating applications requiring deeper board penetration or thicker PCB assemblies. Maintains all other electrical and mechanical compatibility parameters.

929705-06-36-I (3M)

The 3M equivalent provides active product status with extended post length (0.710" / 18.03mm) for specialized applications. Operating temperature range is -40°C ~ 105°C with 2.5A current rating. This part is suitable for applications not requiring the full -65°C lower temperature limit of Amphenol or Sullins alternatives.

Compliance Considerations:

The original 68604-136 is RoHS non-compliant. All substitute parts listed are RoHS compliant (RoHS Compliant or ROHS3 Compliant), meeting current regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 68604-136 with 68604-136HLF?

A: Yes. The 68604-136HLF is the active production equivalent with identical electrical and mechanical specifications. It is the recommended direct replacement for the obsolete 68604-136.

Q: What is the difference between the Sullins PBC36SFAN and PEC36SFAN?

A: Both parts are functionally equivalent with identical pitch, position count, and operating parameters. The primary difference is contact finish: PBC36SFAN uses gold mating contacts, while PEC36SFAN uses tin. Select based on your application's contact finish requirements and compatibility with mating connectors.

Q: Why do some substitute parts have longer post lengths?

A: Post length determines how far the solder tail extends below the PCB. Longer posts (such as PEC36SFCN at 0.320" or 929705-06-36-I at 0.710") accommodate thicker PCB assemblies or applications requiring extended solder joint length. Standard post length (0.120") is suitable for typical single or double-layer PCB designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are RoHS compliant or ROHS3 compliant. The original 68604-136 is RoHS non-compliant. If RoHS compliance is required for your application, select from the substitute parts provided.

Q: What is the difference between board-to-board and board-to-cable style?

A: Board-to-board connectors are designed for direct PCB-to-PCB mating. Board-to-cable connectors can mate with either PCB headers or cable assemblies. Sullins parts (PBC36SFAN, PEC36SFAN, PEC36SFCN) support both styles, providing greater application flexibility than the original board-to-board only design.

Q: Which substitute part should I use if my application requires -65°C operation?

A: Select from 68604-136HLF, PBC36SFAN, PEC36SFAN, or PEC36SFCN. All support -65°C ~ 125°C operating temperature. The 929705-06-36-I (3M) operates only to -40°C and is not suitable for applications requiring -65°C minimum temperature.

Q: What is the current rating difference between parts?

A: The 68604-136HLF, PBC36SFAN, PEC36SFAN, and PEC36SFCN all support 3A current rating. The 929705-06-36-I supports 2.5A. Select based on your application's current requirements per contact.

Q: Can I use these parts interchangeably in my existing PCB design?

A: Mechanical and electrical compatibility is confirmed for all listed parts at the connector interface level. However, verify post length compatibility with your PCB thickness and solder joint requirements. Contact finish differences (gold vs. tin) may affect solderability characteristics; consult your assembly process specifications.
