Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Connector Type & Contact Type: All substitutes must be headers with male pin contacts
• Position Count & Pitch: All substitutes must accommodate 3 positions at 0.100" (2.54mm) pitch
• Mounting & Termination: All substitutes must support through-hole mounting with solder termination
• Fastening Type: All substitutes must feature push-pull fastening
• Insulation Material & Flammability: Substitutes must meet UL94 V-0 flammability rating
• Compliance: All substitutes must be RoHS compliant with MSL 1 rating

Substitute parts are grouped into two categories based on contact material and finish specifications:

Category A - Phosphor Bronze with Gold/Tin Finish (TSW series from Samtec): Maintains phosphor bronze contact material with mixed gold and tin finishes, operating temperature -55°C ~ 125°C, PBT insulation material.

Category B - Alternative Materials (Mill-Max 800 series and Samtec TS series): Brass alloy or alternative contact materials with different finish specifications and insulation materials (PCT or standard thermoplastic).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core functional requirements for 3-position, 0.100" pitch header connectors with through-hole solder termination and push-pull fastening. Selection among substitutes depends on specific design constraints:

Samtec TSW Series (TSW-103-07-L-S, TSW-103-07-S-S, TSW-103-08-T-S, TSW-103-23-L-S, TSW-103-23-S-S, TSW-103-23-T-S, TSW-103-26-G-S) maintain phosphor bronze contact material with UL94 V-0 flammability rating and PBT insulation, providing closest material alignment to the primary part. These parts are ROHS3 compliant with MSL 1 rating. Operating temperature range is -55°C ~ 125°C for most variants, with TSW-103-08-T-S and TSW-103-23-T-S rated to -55°C ~ 105°C.

Samtec TS Series (TS-103-G-AA, TS-103-T-A-1) provide simplified header options with ROHS3 compliance and MSL 1 rating. These parts lack detailed specifications for operating temperature and flammability rating.

Mill-Max 800-10-003-10-001000 offers brass alloy contacts with gold finish on both mating and post surfaces, PCT insulation material, and ROHS3 compliance. Operating temperature and flammability specifications are not provided.

For applications requiring the full operating temperature range of -65°C ~ 125°C, the primary part 77312-150LF is the only option with this specification. For applications operating within -55°C ~ 125°C, Samtec TSW series parts with gold mating finish (TSW-103-07-L-S, TSW-103-23-L-S, TSW-103-23-S-S, TSW-103-26-G-S) provide direct functional equivalence with documented UL94 V-0 compliance.

Frequently Asked Questions (FAQ)

Q: Can TSW-103 series parts directly replace the 77312-150LF?

A: TSW-103 series parts are functionally compatible for applications operating within -55°C ~ 125°C. The primary difference is the lower temperature minimum (-55°C vs. -65°C). Both use phosphor bronze contacts with UL94 V-0 flammability rating and PBT insulation material. All are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between TSW-103-07-L-S and TSW-103-23-L-S?

A: Both parts share identical electrical and mechanical specifications including contact material (phosphor bronze), contact finish (gold mating, tin post), insulation material (PBT), and operating temperature (-55°C ~ 125°C). The designation difference reflects internal design variations not specified in the provided parameters.

Q: Why does the 77312-150LF specify 2 positions loaded while substitutes specify all positions loaded?

A: The 77312-150LF indicates 2 of 3 positions are loaded in the connector body. Substitute parts specify all positions loaded, meaning the connector body accommodates all 3 positions. This does not affect functional compatibility for 3-position applications.

Q: Can the Mill-Max 800-10-003-10-001000 be used in high-temperature applications?

A: Operating temperature specifications are not provided for the Mill-Max part. For applications requiring documented temperature performance, Samtec TSW series parts with specified -55°C ~ 125°C range are recommended.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects durability and wear resistance. The 77312-150LF specifies 30.0µin (0.76µm) gold thickness on mating contacts. TSW-103-07-L-S and TSW-103-23-L-S specify 10.0µin (0.25µm), while TSW-103-07-S-S and TSW-103-23-S-S specify 30.0µin (0.76µm), matching the primary part. For equivalent durability, select parts with matching finish thickness specifications.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The primary part is RoHS compliant. Both designations indicate compliance with RoHS directives; ROHS3 represents the current revision standard.
