Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

The TE Connectivity 8-146274-6 and Samtec HTSW-136-14-T-S, TSW-136-14-G-S-LL, and TSW-136-14-T-S-LL represent the closest electrical and mechanical equivalents. These parts maintain square contact geometry, phosphor bronze or compatible contact materials, and standard insulation heights of 0.100" (2.54mm). All substitute parts listed are RoHS3 compliant or RoHS compliant, addressing regulatory requirements where the original 68629-136 is RoHS non-compliant.

Contact Finish Considerations

The 68629-136 features gold or gold GXT™ mating finish. Samtec TSW series parts with gold finish (TSW-136-14-G-S-LL, TSW-136-16-G-S, TSW-136-25-G-S) maintain this specification. Tin-finished alternatives (TSW-136-14-T-S-LL, TSW-136-16-T-S, TSW-136-25-T-S) are suitable for applications where gold plating is not required. The TE Connectivity 8-146274-6 uses tin finish with 3A current rating, appropriate for standard signal applications.

Post Length Variations

Substitute parts offer three post length categories: 0.110" (2.79mm) for shallow PCB mounting, 0.210" (5.33mm) for standard applications, and 0.310" (7.87mm) for deeper board penetration. Selection depends on PCB thickness and solder joint requirements. The original 68629-136 specifies 0.203" (5.16mm) post length, making the 0.210" (5.33mm) variants most compatible.

Temperature Rating

The original part does not specify operating temperature. Samtec BHS-136-T-B offers the highest temperature rating (-55°C ~ 125°C), suitable for industrial and automotive applications. Standard temperature variants (-55°C ~ 105°C) are adequate for commercial electronics.

Compliance & Availability

All listed substitutes are active products with current inventory. The TE Connectivity 8-146274-6 offers the highest stock level (3,080 units) and RoHS compliance. Samtec TSW series parts provide multiple configuration options with ROHS3 compliance and consistent availability (672–1,107 units per variant).

Frequently Asked Questions (FAQ)

Q: Can I substitute the 68629-136 with any of these parts directly without PCB redesign?

A: Direct substitution depends on post length and insulation height. Parts with 0.100" (2.54mm) insulation height and post lengths between 0.110" and 0.310" are mechanically compatible with standard PCB layouts. The TE Connectivity 8-146274-6 has 0.090" (2.29mm) insulation height, which may require layout verification. The Samtec BHS-136-T-B has 0.335" (8.51mm) insulation height and is not recommended for direct substitution without PCB modification.

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

A: Gold finish provides superior corrosion resistance and lower contact resistance, suitable for high-reliability applications. Tin finish is cost-effective and adequate for standard signal applications with normal environmental conditions. Both finishes are compatible with standard solder reflow processes.

Q: Are kinked pin variants compatible with my application?

A: Samtec TSW-136-14-G-S-LL and TSW-136-14-T-S-LL feature kinked pins for improved solder joint retention. These are mechanically and electrically compatible with standard PCB through-hole mounting. Kinked pins provide additional mechanical strength during assembly and thermal cycling.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS compliance restricts hazardous substances in electrical equipment. The original 68629-136 is RoHS non-compliant. All listed substitutes are RoHS compliant or ROHS3 compliant, meeting regulatory requirements for products sold in the European Union and other regulated markets.

Q: How do I select between different Samtec TSW variants?

A: TSW variants differ in post length (14, 16, 25) and contact finish (G for gold, T for tin, S for mixed finishes). Select post length based on PCB thickness: 14 for thin boards, 16 for standard boards, 25 for thick boards or applications requiring deeper solder penetration. Select finish based on environmental requirements and cost constraints.

Q: Is the TE Connectivity 8-146274-6 breakaway feature compatible with my design?

A: The breakaway feature allows individual positions to be separated after assembly. This is compatible with standard PCB layouts and does not affect electrical performance. If your design does not require breakaway capability, standard non-breakaway variants (Samtec TSW or HTSW series) are equally suitable.

Q: What is the current rating difference between parts?

A: The TE Connectivity 8-146274-6 specifies 3A current rating. Other parts do not specify current rating in the provided data. For high-current applications, verify current capacity with the manufacturer or use the TE Connectivity part with confirmed 3A rating.
