Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical compatibility with the 68634-236H through adherence to critical parameters: 36 positions, 0.100" (2.54mm) pitch, male pin contacts, single-row configuration, through-hole mounting, solder termination, and push-pull fastening with square contact geometry.

Primary Recommendation: 8-146274-6 (TE Connectivity) This part offers the most direct functional replacement with active product status, RoHS compliance, and established supply chain availability. The TE Connectivity AMPMODU Mod II series provides equivalent electrical performance with improved environmental compliance.

Alternative Selections Based on Application Requirements:

For Extended Temperature Range (-55°C to 125°C): TSW series variants (TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-13-F-S) from Samtec provide superior thermal performance compared to the original specification.

For Gold Contact Finish Preference: TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, or PGC36SAAN maintain gold mating surface finish consistent with the original 68634-236H specification.

For Tin Contact Finish: TSW-136-09-T-S and TSW-136-10-T-S provide tin-finished alternatives with equivalent electrical characteristics.

For Samtec HTSW Series: HTSW-136-26-TM-S offers tin finish with phosphor bronze contacts and extended temperature range (-55°C to 105°C).

All substitute parts carry UL94 V-0 flammability certification and EAR99 export classification matching the original component. Active product status ensures long-term availability and supply chain stability for production and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the 68634-236H?

A: All listed parts maintain compatibility with the original 68634-236H footprint and electrical interface. The primary difference is contact length - post dimension, which affects insertion depth. Verify your PCB design accommodates the selected substitute's post length before implementation.

Q: What is the significance of contact length - post variation?

A: Contact length - post determines how far the pin extends below the insulation body. The original 68634-236H has 0.683" (17.35mm) post length. Substitutes range from 0.100" to 0.900". Shorter posts (8-146274-6, HTSW-136-26-TM-S, PGC36SAAN) require less PCB clearance. Longer posts (TSW-136-13-F-S) provide extended insertion depth. Select based on your specific board thickness and clearance requirements.

Q: Why is the original part obsolete?

A: The 68634-236H is classified as obsolete by Amphenol ICC. Active substitute parts from TE Connectivity, Samtec, and Sullins provide equivalent functionality with improved availability and compliance status.

Q: Are all substitutes RoHS compliant?

A: All listed substitutes are RoHS3 compliant or RoHS compliant, representing an improvement over the original 68634-236H which is RoHS non-compliant. This compliance status is beneficial for applications subject to RoHS regulations.

Q: What is the difference between gold and tin contact finishes?

A: Both gold and tin finishes provide adequate contact resistance for this connector class. Gold finishes (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, PGC36SAAN) offer superior corrosion resistance and lower contact resistance. Tin finishes (TSW-136-09-T-S, TSW-136-10-T-S, HTSW-136-26-TM-S, 8-146274-6) are cost-effective alternatives suitable for standard applications. Select based on environmental exposure and contact reliability requirements.

Q: Do all substitutes support the same operating temperature range?

A: Operating temperature ranges vary. The original 68634-236H does not specify a range. Samtec TSW series parts support -55°C to 125°C, providing the widest thermal envelope. TE Connectivity 8-146274-6 supports -65°C to 105°C. HTSW-136-26-TM-S supports -55°C to 105°C. Select based on your application's thermal requirements.

Q: What is the difference between Phosphor Bronze and Copper Alloy contact materials?

A: Both materials provide equivalent electrical performance for this connector class. Phosphor Bronze (original specification and most substitutes) offers consistent spring characteristics. Copper Alloy (8-146274-6, PGC36SAAN) provides alternative material sourcing. Both are acceptable for standard applications.

Q: Can I mix different substitute parts in the same assembly?

A: All listed parts maintain the same 0.100" (2.54mm) pitch and 36-position configuration, allowing interchangeability within a single assembly. However, standardizing on a single part number is recommended for manufacturing consistency and supply chain management.

Q: What packaging options are available?

A: Most substitutes are supplied in bulk packaging. Verify packaging specifications with your supplier for quantity requirements and handling procedures.

Q: Are there any moisture sensitivity considerations?

A: Most substitutes carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. HTSW-136-26-TM-S is rated Not Applicable. All parts are suitable for standard storage and handling without special moisture control measures.
