TMS-135-01-G-D-RA Equivalent & Substitute Parts

Part Overview

The TMS-135-01-G-D-RA is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc. This through-hole, right-angle board-to-board connector features 70 positions across 2 rows with unshrouded design and push-pull fastening. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply constraints, lead time considerations, or design revision requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TMS-135-01-G-D-RA is determined by the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 70
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Current Rating: 5A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

The substitute part HTMS-135-01-G-D-RA maintains all critical electrical and mechanical parameters within acceptable tolerances. Both parts are manufactured by Samtec Inc., share identical pitch, position count, row configuration, and mounting characteristics. Insulation height variance (0.197" vs 0.196") falls within standard manufacturing tolerances and does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TMS-135-01-G-D-RA and HTMS-135-01-G-D-RA are active production parts from Samtec Inc. with identical compliance certifications including ROHS3 compliance and UL94 V-0 flammability rating. Selection between these parts should be based on availability and lead time requirements, as both parts meet all specified electrical and mechanical requirements for board-to-board interconnection applications requiring 0.050" pitch micro header connectors with 70-position, 2-row configuration.

Frequently Asked Questions (FAQ)

Q: Can HTMS-135-01-G-D-RA be used as a direct replacement for TMS-135-01-G-D-RA?

A: Yes. Both connectors share identical pitch (0.050"), position count (70), row configuration (2 rows), row spacing (0.100"), mounting type (through-hole right-angle), contact material (phosphor bronze), contact finish (gold), current rating (5A per contact), and operating temperature range (-55°C to 125°C). The insulation height difference of 0.001" (0.02mm) is within standard manufacturing tolerances and does not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level. Both are active production parts from Samtec Inc.

Q: What determines compatibility for substitute rectangular connectors in this pitch class?

A: Compatibility is determined by matching pitch (0.050"), position count (70), row count (2), row spacing (0.100"), mounting configuration (through-hole right-angle), contact type (male pin), termination method (solder), contact material (phosphor bronze), contact finish (gold), current rating (5A per contact), and operating temperature range (-55°C to 125°C).

Q: Can these connectors be used in applications requiring different current ratings?

A: No. Both connectors are rated for 5A per contact. Applications requiring different current ratings require alternative connector models.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. Inventory availability differs: TMS-135-01-G-D-RA has 1061 pcs in stock, while HTMS-135-01-G-D-RA has 1180 pcs in stock.
