Engineering Selection Recommendations
Primary Recommendation: HTSW-136-26-TM-S (Samtec Inc.)
The HTSW-136-26-TM-S is the manufacturer-recommended substitute. This part maintains full electrical and mechanical compatibility with the 68705-136 while offering active product status and ROHS3 compliance. The LCP insulation material provides superior thermal and chemical resistance compared to the original specification. Operating temperature range of -55°C to 105°C covers the original application envelope.
Secondary Recommendations:
Sullins PBC36SAAN / PBC36SABN Series – Active status with ROHS3 compliance. PBT insulation material and extended operating temperature range (-65°C to 125°C) provide design margin. PBC36SAAN features shorter post length (0.120") for standard applications; PBC36SABN provides extended post length (0.230") for applications requiring deeper board penetration.
Sullins PEC36SAAN / PEC36SABN Series – Tin-plated mating contacts with ROHS3 compliance. PEC36SAAN offers standard post length (0.120"); PEC36SABN provides extended post length (0.230"). Extended operating temperature range (-65°C to 125°C) supports demanding environments.
Samtec TSW Series – Multiple post length options accommodate various PCB thickness and stacking requirements. TSW-136-07-F-S (0.100" post), TSW-136-09-G-S (0.400" post, gold finish), TSW-136-09-T-S (0.400" post, tin finish), and TSW-136-10-G-S (0.500" post) provide flexibility for specific mechanical constraints. All TSW variants feature ROHS3 compliance and active product status.
Sullins PGC36SAAN – Copper alloy contacts with gold finish on both mating and post surfaces. Suitable for applications requiring enhanced corrosion resistance and contact reliability.
All substitute parts are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.
Frequently Asked Questions (FAQ)
Q: Can I directly replace the 68705-136 with any of these substitute parts?
A: Yes. All listed substitute parts maintain the critical 36-position, 0.100" (2.54mm) pitch header configuration with through-hole solder termination and push-pull fastening. The primary design consideration is contact length post dimension, which varies by application. Standard applications use 0.095" to 0.120" post length; applications requiring deeper board penetration use 0.230" to 0.500" post length.
Q: What is the difference between gold and tin contact finishes?
A: Gold-plated contacts (68705-136, PBC36SAAN, PGC36SAAN, TSW-136-09-G-S, TSW-136-10-G-S) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts (HTSW-136-26-TM-S, PEC36SAAN, PEC36SABN, TSW-136-09-T-S) are cost-effective and suitable for standard applications with adequate environmental protection.
Q: Why is the original part obsolete?
A: The 68705-136 is classified as obsolete by the manufacturer. All substitute parts listed carry active product status, ensuring continued availability, technical support, and compliance with current regulatory standards including ROHS3.
Q: Does contact length post dimension affect PCB compatibility?
A: Yes. Contact length post dimension determines how deeply the connector penetrates the PCB. The original 68705-136 uses 0.095" post length. Substitute parts range from 0.100" to 0.500" post length. Select post length based on your PCB thickness and stacking height requirements. Shorter post lengths (0.100" to 0.120") suit standard PCB applications; longer post lengths (0.230" to 0.500") accommodate thicker boards or applications requiring extended mating depth.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance. The original 68705-136 is RoHS non-compliant. Substitution with any listed part ensures compliance with current environmental and regulatory requirements.
Q: What insulation materials are used in substitute parts?
A: Substitute parts use PBT (Polybutylene Terephthalate), LCP (Liquid Crystal Polymer), or Thermoplastic Polyester insulation. All materials meet UL94 V-0 flammability requirements. LCP (HTSW-136-26-TM-S) offers superior thermal stability; PBT (Sullins and most Samtec parts) provides cost-effective performance for standard applications.
Q: Can I mix gold and tin contact finishes in the same application?
A: Contact finish selection should be consistent within a mating pair to avoid galvanic corrosion. Select either gold-plated or tin-plated parts based on your environmental requirements and cost constraints, then maintain that finish type throughout the design.
Q: What is the current rating for these connectors?
A: The original 68705-136 specifies 5A current rating. Substitute parts from Sullins (PBC36SAAN, PBC36SABN, PEC36SAAN, PEC36SABN, PGC36SAAN) specify 3A current rating. Samtec TSW series parts do not specify current rating in the provided data. Verify current requirements against your application specifications before final part selection.
