Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-121-06-S-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 21 positions, single row
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Contact Materials & Finishes: Phosphor bronze with gold mating finish and tin post finish
• Insulation Material: Polybutylene Terephthalate (PBT)
• Environmental Ratings: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating
• Compliance Standards: ROHS3 compliance and REACH unaffected status

Only parts meeting all these criteria qualify as direct substitutes. The provided substitute part list contains the TSW-121-06-S-S from Samtec Inc., which is identical to the main part number.

Parameter Comparison

Engineering Selection Recommendations

The TSW-121-06-S-S substitute part is electrically and mechanically identical to the main part, with all critical parameters matching exactly. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental certifications. The primary distinction is product status: the main part is currently active in production, while the substitute is discontinued at DiGi Electronics. For new designs and long-term supply requirements, the active main part is the preferred selection. The substitute part may be considered only when the main part is unavailable and existing inventory from alternative distributors is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the TSW-121-06-S-S substitute part be used interchangeably with the main part?

A: Yes, from an electrical and mechanical standpoint, both parts are identical. All contact configurations, pitch specifications, termination methods, and material compositions match exactly. However, the substitute part is discontinued at DiGi Electronics, making it unsuitable for new production designs requiring long-term availability.

Q: What parameters must match for a part to qualify as a substitute for the TSW-121-06-S-S?

A: Critical matching parameters include 21-position single-row configuration, 0.100" (2.54mm) pitch, male pin contact type, through-hole solder termination, phosphor bronze contact material with gold mating finish and tin post finish, PBT insulation, and operating temperature range of -55°C ~ 125°C.

Q: Are there any compliance or certification differences between the main part and substitute?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

Q: What should be considered when selecting between the main part and substitute?

A: Product availability and supply chain continuity are the primary considerations. The main part is active and recommended for new designs. The substitute should only be selected if the main part is unavailable and the substitute is confirmed in stock from an alternative distributor.
