Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS-106-03-S-S-RA is determined by the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 6
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 5A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain compatibility across all critical electrical and mechanical parameters. Variations in series designation (TMS vs. HTMS) and minor insulation height differences do not affect functional interchangeability in applications requiring 0.050" pitch, 6-position, single-row through-hole right-angle headers with solder termination.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—TMS-106-03-S-S-RA, HTMS-106-03-S-S-RA, and TMS-106-03-SM-S-RA—are active products manufactured by Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on availability and inventory status rather than electrical or mechanical performance differences, as all three maintain identical specifications for pitch, position count, contact material, termination method, and operating temperature range.

The HTMS-106-03-S-S-RA variant features a marginally reduced insulation height of 0.096" (2.44mm) compared to 0.098" (2.50mm) in the TMS series. This minor dimensional difference does not affect functional compatibility in standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can TMS-106-03-S-S-RA be directly replaced with HTMS-106-03-S-S-RA?

A: Yes. Both parts share identical electrical specifications, contact pitch, position count, and termination characteristics. The insulation height difference of 0.002" (0.06mm) is negligible for most applications and does not affect mating or performance.

Q: What is the difference between TMS-106-03-S-S-RA and TMS-106-03-SM-S-RA?

A: Both are TMS series headers with identical electrical and mechanical specifications. The designation difference reflects internal Samtec product line categorization but does not indicate functional variation. Both are suitable for 0.050" pitch, 6-position applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. TMS-106-03-S-S-RA, HTMS-106-03-S-S-RA, and TMS-106-03-SM-S-RA are all ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the current rating for these connectors?

A: All three parts are rated for 5A per contact, supporting applications requiring up to 30A total current capacity across all six positions.

Q: Can these connectors operate in extended temperature environments?

A: Yes. All three parts maintain specifications across the -55°C to 125°C operating temperature range, suitable for industrial and automotive applications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
