TMS-150-01-T-S-RA Equivalent & Substitute Parts

Part Overview

The TMS-150-01-T-S-RA is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc. This through-hole, right-angle rectangular connector features 50 positions in a single row configuration with male pin contacts and push-pull fastening. The connector is designed for board-to-board applications and is currently in active production status. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS-150-01-T-S-RA is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 50
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -55°C ~ 105°C
• Current Rating: 5A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The HTMS-150-01-T-S-RA meets all critical substitution criteria. Minor variations in insulation height (0.098" vs 0.096") fall within acceptable mechanical tolerances for board-to-board connector applications and do not affect electrical performance or mating compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HTMS-150-01-T-S-RA is a direct functional equivalent to the TMS-150-01-T-S-RA. Both connectors are manufactured by Samtec Inc., maintain identical electrical specifications, and carry equivalent compliance certifications including ROHS3 compliance and UL94 V-0 flammability rating. Both parts are in active production status.

The minor insulation height difference of 0.002" (0.06mm) between the two parts is within standard manufacturing tolerances for this connector category and does not impact electrical performance, mating compatibility, or board-level integration. Selection between these parts should be based on inventory availability and supply chain requirements rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are TMS-150-01-T-S-RA and HTMS-150-01-T-S-RA electrically interchangeable?

A: Yes. Both connectors feature identical electrical specifications including 0.050" (1.27mm) pitch, 50 positions, 5A per contact current rating, and -55°C to 105°C operating temperature range. They are electrically interchangeable in all applications.

Q: What is the significance of the insulation height difference?

A: The insulation height difference of 0.002" (0.06mm) is within standard manufacturing tolerances for micro header connectors. This variation does not affect mating performance, board-level clearances, or connector functionality.

Q: Can these connectors be used interchangeably in PCB designs?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), contact pitch, and position count. PCB footprints designed for one connector will accommodate the other without modification.

Q: Are both parts RoHS compliant?

A: Yes. Both TMS-150-01-T-S-RA and HTMS-150-01-T-S-RA are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the difference between the TMS and HTMS series designations?

A: The series designation reflects the product line within Samtec's connector portfolio. Both series employ identical electrical and mechanical specifications for this 0.050" pitch, 50-position header configuration. Selection between series should be based on availability and supply chain considerations.
