Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the MTSW-104-08-T-S-130-RE. Each part is manufactured by Samtec Inc., carries active product status, and meets ROHS3 compliance and UL94 V-0 flammability requirements. Selection among these equivalents should be based on inventory availability and lead time requirements specific to procurement needs. No performance degradation or functional limitation occurs when substituting between these parts in applications designed for the MTSW-104 base product family.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically equivalent to the MTSW-104-08-T-S-130-RE?

A: Yes. All substitute parts maintain identical electrical specifications including 3A current rating, operating temperature range of -55°C to 105°C, and contact material composition (Phosphor Bronze with Tin finish).

Q: What determines compatibility between the main part and substitute parts?

A: Compatibility is determined by equivalence across connector type, contact configuration, pitch, mounting method, contact dimensions, insulation material, and termination type. All listed substitutes match these parameters without exception.

Q: Do the substitute parts have different packaging or moisture sensitivity classifications?

A: The MTSW-104-07-T-S-130-NA, MTSW-104-07-T-S-130-RA, MTSW-104-08-T-S-130-RA, and MTSW-104-23-T-S-130-RA may differ in moisture sensitivity level classification, but this does not affect electrical or mechanical performance in standard applications. All parts are supplied in bulk packaging.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical pitch (0.100"), mounting type (through-hole right-angle), contact dimensions, and insulation height ensure direct mechanical and electrical interchangeability in PCB layouts designed for the MTSW-104 series.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and carry UL94 V-0 material flammability certification.
