Substitute Part Grouping Explanation

Substitution for the 68705-236H is determined by strict alignment of core electrical and mechanical parameters: 36-position configuration, 0.100" (2.54mm) pitch, male pin contact type, through-hole solder termination, square contact shape, 0.100" insulation height, and UL94 V-0 flammability rating. Substitute parts must maintain these specifications to ensure mechanical and electrical compatibility in existing PCB designs.

The substitute parts are grouped into two categories based on contact finish and material composition:

Category 1: Gold-Plated Mating Contacts (Phosphor Bronze)

PBC36SAAN, PBC36SABN, PGC36SAAN, TSW-136-09-G-S, TSW-136-10-G-S

Category 2: Tin-Plated or Mixed Finish Contacts

HTSW-136-26-TM-S, PEC36SAAN, PEC36SABN, TSW-136-07-F-S, TSW-136-09-T-S

All substitute parts maintain the 36-position, 2.54mm pitch, through-hole solder configuration and UL94 V-0 rating required for direct substitution.

Engineering Selection Recommendations

All listed substitute parts maintain the core 36-position, 0.100" pitch, male pin, through-hole solder configuration required for direct mechanical and electrical compatibility with the 68705-236H.

For RoHS3 Compliance: All substitute parts are ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. Selection between substitutes should prioritize active product status and extended operating temperature ranges where applicable.

Contact Finish Considerations: Gold-plated mating contact finishes (PBC36SAAN, PBC36SABN, PGC36SAAN, TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-10-G-S) provide corrosion resistance comparable to the original part. Tin-plated alternatives (HTSW-136-26-TM-S, PEC36SAAN, PEC36SABN, TSW-136-09-T-S) are suitable for standard environmental conditions and offer cost optimization.

Operating Temperature Range: Samtec TSW series and Sullins PBC/PEC series parts support -55°C to 125°C operating range, exceeding the original part's unspecified range. HTSW-136-26-TM-S operates to -55°C to 105°C. Selection depends on application thermal requirements.

Insulation Material: Substitute parts use PBT or LCP insulation materials, both rated UL94 V-0, maintaining flammability compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 68705-236H be directly replaced with any of these substitute parts?

A: Yes, all listed substitute parts maintain the critical parameters for direct substitution: 36 positions, 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, square contact shape, and UL94 V-0 flammability rating. Physical and electrical compatibility is maintained across all substitutes.

Q: What is the primary difference between gold-plated and tin-plated mating contacts?

A: Gold-plated contacts provide enhanced corrosion resistance and are suitable for applications requiring extended shelf life or harsh environmental exposure. Tin-plated contacts are suitable for standard environmental conditions and offer cost advantages. Both finishes maintain electrical performance within standard operating parameters.

Q: Does the contact post length affect substitution compatibility?

A: Contact post length varies among substitutes (ranging from 0.095" to 0.500"), but this parameter does not affect substitution compatibility as it is determined by PCB design and does not impact mating interface performance. Selection should align with specific PCB through-hole depth requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts are ROHS3 compliant. The original 68705-236H is RoHS non-compliant, making these substitutes necessary for designs requiring regulatory compliance.

Q: What is the significance of the operating temperature range difference?

A: The original part does not specify an operating temperature range. Substitute parts specify ranges from -55°C to 105°C or -55°C to 125°C. For applications operating within standard industrial temperature ranges (-40°C to 85°C), all substitutes are suitable. Applications requiring extended temperature operation should select parts with -55°C to 125°C ratings.

Q: Can I mix different substitute part numbers in the same design?

A: All substitute parts are mechanically and electrically compatible with each other due to identical pitch, position count, and contact configuration. However, for manufacturing consistency and traceability, using a single part number across a design is recommended.
