Engineering Selection Recommendations

Active Production Parts (Recommended for New Designs):

The 77313-122-10LF, 77313-124-10LF, 77313-127-10LF, and 77313-824-10LF from Amphenol ICC (FCI) BERGSTIK® series are all active production parts with extended operating temperature ranges (-65°C to 130°C), exceeding the MTSW-105-08-L-D-235 specification. These parts are RoHS compliant and provide gold-plated mating contacts with GXT™ coating options. The 826632-5 from TE Connectivity AMPMODU Mod II series is also active and offers a higher current rating of 5A, though its maximum operating temperature is limited to 105°C.

The PBC05DAAN from Sullins Connector Solutions is an active production part with ROHS3 compliance and gold-plated contacts. It maintains the 3A current rating and -65°C to 125°C operating temperature range.

Obsolete Part (Not Recommended for New Designs):

The 67996-410 from Amphenol ICC (FCI) BERGSTIK® II series is marked as obsolete and should not be selected for new designs. While it meets the core electrical and mechanical parameters, its discontinued status creates supply chain risk.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability ratings. The MTSW-105-08-L-D-235, 77313-122-10LF, 77313-124-10LF, 77313-127-10LF, 77313-824-10LF, and PBC05DAAN are ROHS3 compliant. The 67996-410 and 826632-5 are RoHS compliant but not explicitly ROHS3 certified.

Frequently Asked Questions (FAQ)

Q: Can the 77313-122-10LF be used as a direct replacement for the MTSW-105-08-L-D-235?

A: Yes. Both parts share identical pitch (0.100"), position count (10), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination (solder). Both are UL94 V-0 rated and RoHS compliant. The 77313-122-10LF offers an extended operating temperature range (-65°C to 130°C versus -55°C to 125°C) and gold-plated mating contacts with GXT™ coating option.

Q: What is the difference between the 77313-124-10LF and 77313-127-10LF?

A: Both parts are from the Amphenol ICC BERGSTIK® series with identical electrical specifications. The primary difference is in contact length dimensions. The 77313-124-10LF has a mating contact length of 0.266" (6.75mm) and overall contact length of 0.480" (12.19mm), while the 77313-127-10LF has a mating contact length of 0.260" (6.60mm) and overall contact length of 0.465" (11.81mm). Both maintain the same operating temperature range and current rating.

Q: Why is the 67996-410 listed if it is obsolete?

A: The 67996-410 is included for reference purposes for existing designs or legacy systems currently using this part. However, it is not recommended for new designs due to its discontinued status. Active alternatives should be selected instead.

Q: Does the 826632-5 offer any advantages over the MTSW-105-08-L-D-235?

A: The 826632-5 provides a higher current rating of 5A compared to the 3A rating of the MTSW-105-08-L-D-235, making it suitable for higher-current applications. However, its maximum operating temperature is limited to 105°C, which is lower than the MTSW-105-08-L-D-235 specification of 125°C. Selection depends on whether current capacity or temperature range is the limiting factor in your application.

Q: Are there any insulation material differences between substitute parts?

A: Yes. The MTSW-105-08-L-D-235 uses polyester glass-filled insulation. The Amphenol ICC BERGSTIK® parts (77313 series) use thermoplastic insulation. The TE Connectivity 826632-5 uses polybutylene terephthalate (PBT), and the Sullins PBC05DAAN also uses PBT. All materials meet UL94 V-0 flammability requirements. Material selection may affect mechanical properties and environmental resistance in specific applications.

Q: Is the PBC05DAAN suitable for applications requiring ROHS3 compliance?

A: Yes. The PBC05DAAN is ROHS3 compliant and maintains all core electrical and mechanical compatibility with the MTSW-105-08-L-D-235. It features gold-plated mating contacts, phosphor bronze contact material, and a 3A current rating across the -65°C to 125°C operating temperature range.
