MTSW-102-22-T-S-220-RA Equivalent & Substitute Parts

Part Overview

The MTSW-102-22-T-S-220-RA is an active rectangular connector header manufactured by Samtec Inc. from the Flex Stack MTSW series. This through-hole, right-angle 2-position connector operates at 0.100" (2.54mm) pitch and is designed for board-to-board or cable applications. The part is ROHS3 compliant and carries UL94 V-0 flammability certification. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in compatible applications.

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-102-22-T-S-220-RA is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 2
Number of Rows: 1
Contact Type: Male Pin
Mounting Type: Through Hole, Right Angle
Termination: Solder
Fastening Type: Push-Pull
Contact Shape: Square
Insulation Material: Polyester, Glass Filled
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts (Molex 0901210122 and 0901210762) match all critical parameters. Variations in contact length, insulation height, contact material composition, and contact finish specifications are within acceptable tolerance ranges for equivalent functionality in board-to-board and cable applications.

Engineering Selection Recommendations

Both Molex substitute parts (0901210122 and 0901210762) are active products with ROHS3 compliance and UL94 V-0 flammability certification, matching the regulatory and compliance profile of the MTSW-102-22-T-S-220-RA.

The 0901210122 is packaged in trays and features tin-plated mating contacts. The 0901210762 is packaged in bulk with gold-plated mating contacts. Both parts maintain identical pitch, position count, row configuration, contact type, mounting orientation, termination method, and fastening mechanism.

Selection between these substitutes depends on packaging requirements and contact finish specifications for the application. The gold-plated finish of the 0901210762 provides enhanced corrosion resistance compared to the tin-plated alternatives.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901210122 or 0901210762 directly replace the MTSW-102-22-T-S-220-RA?

A: Yes. Both Molex parts share identical mating pitch (0.100"), position count (2), row configuration (1), contact type (male pin), mounting type (through-hole right-angle), termination (solder), and fastening mechanism (push-pull). All three parts carry UL94 V-0 certification and ROHS3 compliance.

Q: What are the differences in contact dimensions between the main part and substitutes?

A: The MTSW-102-22-T-S-220-RA has a mating contact length of 0.220" (5.59mm) and post length of 0.090" (2.29mm). Both Molex substitutes have longer contacts: 0.266" (6.75mm) mating and 0.114" (2.90mm) post. Insulation height also differs: 0.119" (3.02mm) for the Samtec part versus 0.142" (3.60mm) for the Molex parts.

Q: How do contact materials differ?

A: The MTSW-102-22-T-S-220-RA uses phosphor bronze contacts. Both Molex substitutes use brass contacts. Both materials are suitable for the specified push-pull fastening and solder termination applications.

Q: What is the difference between the two Molex substitute parts?

A: The primary difference is contact finish. The 0901210122 features tin-plated mating contacts, while the 0901210762 features gold-plated mating contacts. The 0901210762 also differs in packaging (bulk versus tray). Both maintain identical electrical and mechanical specifications otherwise.

Q: Are there packaging considerations for substitution?

A: The MTSW-102-22-T-S-220-RA is supplied in bulk packaging. The 0901210122 is supplied in trays, while the 0901210762 is supplied in bulk. Packaging selection should align with procurement and assembly workflow requirements.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry UL94 V-0 flammability certification, have MSL rating of 1 (Unlimited), and are REACH unaffected with EAR99 ECCN classification.
