Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-11-G-S-NA is determined by the following critical parameters:

Connector Type & Contact Type: Must be Header with Male Pin configuration
Number of Positions & Rows: Must maintain 2 positions in 1 row
Pitch - Mating: Must be 0.100" (2.54mm)
Mounting Type: Must be Through Hole, Right Angle
Termination: Must be Solder
Contact Finish - Mating: Must be Gold
Contact Material: Must be Phosphor Bronze
Operating Temperature Range: Must support -55°C ~ 125°C
Material Flammability Rating: Must meet UL94 V-0
RoHS Status: Must be ROHS3 Compliant

The three identified substitute parts meet all critical electrical and mechanical parameters. Variations exist in insulation material (PBT vs. LCP), insulation height tolerance, insulation color, and MSL classification, which do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

All three substitute parts are Active status products from Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Selection between TSW-102-11-G-S-NA and its substitutes should be based on:

TSW-102-11-G-S-RA: Identical electrical and mechanical specifications to the main part. Suitable for direct replacement with no design modifications required.

TSW-102-11-G-S-RE: Identical electrical and mechanical specifications to the main part. Suitable for direct replacement with no design modifications required.

HTSW-102-12-G-S-RE: Differs in insulation material (LCP vs. PBT) and insulation height (0.122" vs. 0.119"). The HTSW series uses LCP insulation with MSL classification of Not Applicable. This part is suitable where LCP material properties are acceptable and board layout accommodates the 0.003" insulation height difference.

All parts maintain identical contact geometry, pitch, operating temperature range, and gold-plated phosphor bronze contact specifications.

Frequently Asked Questions (FAQ)

Q: Can TSW-102-11-G-S-RA be used as a direct replacement for TSW-102-11-G-S-NA?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting type, contact materials, and operating temperature range. No design modifications are required.

Q: What is the difference between TSW-102-11-G-S-NA and TSW-102-11-G-S-RE?

A: Both parts are functionally equivalent with identical specifications. The difference is in the part number suffix, which may indicate different manufacturing batches or distribution channels. Electrical and mechanical compatibility is maintained.

Q: Can HTSW-102-12-G-S-RE replace TSW-102-11-G-S-NA?

A: HTSW-102-12-G-S-RE is electrically and mechanically compatible. The primary differences are insulation material (LCP instead of PBT) and insulation height (0.122" vs. 0.119"). Verify that board layout and mechanical clearances accommodate the 0.003" height difference. The LCP material maintains UL94 V-0 compliance and ROHS3 status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the main part TSW-102-11-G-S-NA and all substitutes, are ROHS3 compliant.

Q: What is the significance of the MSL rating difference?

A: TSW-102-11-G-S-NA, TSW-102-11-G-S-RA, and TSW-102-11-G-S-RE are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. HTSW-102-12-G-S-RE is rated Not Applicable, which is typical for LCP-based connectors. Both classifications are suitable for standard storage and handling conditions.

Q: Do all parts support the same operating temperature range?

A: Yes. All parts operate across -55°C to 125°C, maintaining full electrical and mechanical performance within this range.
