Substitute Part Grouping Explanation

Substitution eligibility for the TMS-101-02-G-S-RA is determined by strict alignment of the following critical parameters:

  • Connector Type & Configuration: Header, single position, single row, board-to-board style
  • Pitch Specification: 0.050" (1.27mm) mating pitch
  • Mounting & Termination: Through-hole, right-angle mounting with solder termination
  • Contact Specifications: Male pin, square contact shape, phosphor bronze material with gold plating
  • Electrical Rating: 5A per contact minimum
  • Environmental Compliance: UL94 V-0 flammability, RoHS3 compliance, operating range -55°C to 125°C
  • Insulation Material: Liquid Crystal Polymer (LCP)

The HTMS-101-02-G-S-RA qualifies as a direct substitute based on matching all critical parameters within acceptable mechanical tolerances.

Engineering Selection Recommendations

Both the TMS-101-02-G-S-RA and HTMS-101-02-G-S-RA are active production components from Samtec Inc. with full RoHS3 compliance and UL94 V-0 certification. The HTMS-101-02-G-S-RA represents a valid substitute with functionally equivalent electrical and mechanical characteristics. The insulation height variance of 0.004" (0.10mm) between the two parts falls within standard manufacturing tolerances and does not affect connector mating or board-level compatibility.

Selection between these parts should be based on availability, lead time, and inventory requirements, as both components meet identical performance and compliance specifications for through-hole, right-angle micro header applications.

Frequently Asked Questions (FAQ)

Q: Can HTMS-101-02-G-S-RA be used as a direct replacement for TMS-101-02-G-S-RA?

A: Yes. Both parts share identical connector type, pitch, mounting configuration, contact specifications, and electrical ratings. The minor insulation height difference (0.004") is within acceptable manufacturing tolerance and does not impact functional compatibility.

Q: Are there any differences in contact plating between these parts?

A: No. Both parts feature identical gold plating specifications: 10.0µin (0.25µm) on mating surfaces and 3.00µin (0.076µm) on post surfaces.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both TMS-101-02-G-S-RA and HTMS-101-02-G-S-RA are RoHS3 compliant, UL94 V-0 rated, and rated for -55°C to 125°C operation with 5A per contact current capacity.

Q: What is the significance of the series designation change from TMS to HTMS?

A: The series designation reflects the product line classification within Samtec's connector portfolio. Both series utilize identical connector architecture and specifications for this single-position, 0.050" pitch header configuration.

Q: Are there packaging or inventory considerations when selecting between these parts?

A: Both parts are supplied in bulk packaging. Selection should consider current inventory levels and supply chain lead times, as both components are in active production status.
