Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMS-134-01-G-S-RA are identified based on strict equivalence of the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 34
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 5A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The HTMS-134-01-G-S-RA qualifies as a substitute part because it maintains all critical electrical and mechanical parameters required for functional compatibility. Both connectors share identical pitch spacing, position count, contact configuration, and performance ratings. Variations in insulation height (0.098" vs 0.096") remain within acceptable mechanical tolerances for board-to-board interface applications.
