Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS-105-59-L-S is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 5
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact dimensions (Mating, Post, Overall)
• Insulation Height: 0.100" (2.54mm)
• Contact Material: Phosphor Bronze
• Contact Finish specifications (Mating and Post)
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature range: -55°C ~ 125°C
• Current Rating: 5A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The HTMS-105-59-L-S meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The HTMS-105-59-L-S is a direct equivalent substitute for the TMS-105-59-L-S. Both parts are manufactured by Samtec Inc., carry active product status, and maintain identical electrical and mechanical specifications across all critical parameters. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts may be based on inventory availability. The TMS-105-59-L-S currently has 815 units in stock, while the HTMS-105-59-L-S has 826 units available. Both parts are suitable for immediate deployment in applications requiring 0.050" pitch, 5-position through-hole header connectors with 5A per contact current capacity and -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can HTMS-105-59-L-S be used as a direct replacement for TMS-105-59-L-S?

A: Yes. The HTMS-105-59-L-S is a direct equivalent. All electrical and mechanical parameters, including pitch, contact dimensions, materials, finishes, current rating, temperature range, and compliance certifications are identical.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: 0.050" (1.27mm) pitch, 5 positions in 1 row, male pin contacts, through-hole solder termination, identical contact dimensions (0.535" mating length, 0.120" post length), phosphor bronze material with gold-plated mating contacts and tin-plated posts, LCP insulation, 5A per contact current rating, -55°C to 125°C operating temperature, and UL94 V-0 flammability rating.

Q: Are there any differences in packaging or handling between these parts?

A: Both parts are supplied in bulk packaging with identical moisture sensitivity level classification (MSL 1 - Unlimited), indicating no special storage or handling requirements beyond standard component care.

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

A: The TMS-105 and HTMS-105 represent different series within Samtec's micro header product line. The HTMS designation indicates a through-hole variant within the HTMS series, while TMS represents the standard TMS series. Despite the series designation difference, the TMS-105-59-L-S and HTMS-105-59-L-S maintain complete parameter equivalence for substitution purposes.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Identical contact dimensions, pitch, insulation height, and mounting type ensure both parts are compatible with the same PCB footprint and assembly process.
