Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-104-09-L-S-430-RA is determined by strict equivalence across the following critical parameters:

  • Manufacturer and series consistency (Samtec Inc., Flex Stack MTSW)
  • Connector type and contact configuration (Header, Male Pin, Cuttable)
  • Position count and pitch (4 positions, 0.100" / 2.54mm)
  • Mounting orientation and termination method (Through Hole, Right Angle, Solder)
  • Contact dimensions and finishes (Mating contact length 0.430", Post length 0.090", Gold mating finish, Tin post finish)
  • Electrical and thermal ratings (3A current, -55°C ~ 125°C operating range)
  • Compliance certifications (UL94 V-0, ROHS3 Compliant)

The substitute part MTSW-104-10-L-S-430-RE meets all these criteria and is classified as a direct equivalent within the same product family.

Engineering Selection Recommendations

Both the MTSW-104-09-L-S-430-RA and MTSW-104-10-L-S-430-RE are active production parts from Samtec Inc. with identical electrical, mechanical, and thermal specifications. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts may be based on inventory availability, lead time, or procurement cost, as they are functionally equivalent for all specified applications. The MTSW-104-10-L-S-430-RE currently has higher inventory availability at 1036 units compared to 830 units for the primary part.

Frequently Asked Questions (FAQ)

Q: Are MTSW-104-09-L-S-430-RA and MTSW-104-10-L-S-430-RE interchangeable?

A: Yes. Both parts are direct equivalents with identical contact configurations, pitch, mating contact length, post length, insulation height, and electrical ratings. They are both through-hole, right-angle headers in the Flex Stack MTSW series with 4 positions at 0.100" (2.54mm) pitch.

Q: What determines substitution eligibility for this connector family?

A: Substitution is based on matching the following parameters: manufacturer (Samtec Inc.), series (Flex Stack MTSW), connector type (Header, Cuttable), contact type (Male Pin), position count (4), pitch (0.100" / 2.54mm), mounting type (Through Hole, Right Angle), contact dimensions (0.430" mating length, 0.090" post length), contact finishes (Gold mating, Tin post), current rating (3A), operating temperature range (-55°C ~ 125°C), and compliance certifications (UL94 V-0, ROHS3).

Q: Can these parts be used in applications requiring different operating temperatures?

A: No. Both parts are rated for -55°C ~ 125°C operation. Applications requiring different temperature ranges require alternative part selection outside this family.

Q: Are there any differences in packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The MTSW-104-10-L-S-430-RE has higher current inventory availability, which may affect procurement timelines.

Q: Do both parts meet the same compliance standards?

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