TSW-112-15-G-S-LL Equivalent & Substitute Parts

Part Overview

The TSW-112-15-G-S-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 12-position, single-row header operates at 0.100" (2.54mm) pitch and features kinked pin solder termination with gold-plated mating contacts. The part maintains Active product status with full RoHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified to address inventory availability, obsolescence concerns, or specific application requirements while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-15-G-S-LL is determined by the following critical parameters:

• 12-position, single-row configuration with 0.100" (2.54mm) pitch mating spacing
• Through-hole mounting with solder termination
• Male pin contact type with gold-plated mating surface
• Board-to-board or cable connection style
• Unshrouded design with square contact geometry
• UL94 V-0 flammability compliance

The substitute part 4-102972-0-12 (TE Connectivity AMP Connectors AMPMODU Mod II series) satisfies these core electrical and mechanical requirements. However, this part carries Obsolete product status and RoHS non-compliance, which may restrict its use in new designs or regulated applications.

Parameter Comparison

Engineering Selection Recommendations

The TSW-112-15-G-S-LL is the preferred choice for new designs and applications requiring RoHS3 compliance. Its Active product status ensures long-term availability and supply chain stability.

The 4-102972-0-12 substitute is suitable only for legacy system maintenance, repair, or applications where RoHS compliance is not mandated. The Obsolete product status indicates discontinued manufacturing, limiting future procurement options. Selection of this substitute should be restricted to situations where the TSW-112-15-G-S-LL is unavailable and design flexibility permits accommodation of dimensional and material differences.

Key compliance considerations: The TSW-112-15-G-S-LL meets ROHS3 requirements; the 4-102972-0-12 does not. Applications subject to EU, California, or equivalent regulatory frameworks must use the TSW-112-15-G-S-LL or equivalent RoHS-compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 4-102972-0-12 be used as a direct replacement for the TSW-112-15-G-S-LL?

A: Both parts share the same 12-position, 0.100" (2.54mm) pitch configuration and through-hole solder termination, making them mechanically and electrically compatible at the board interface level. However, dimensional differences exist: the 4-102972-0-12 has a shorter mating contact length (0.318" vs. 0.520") and lower insulation height (0.090" vs. 0.100"). These differences may affect mating depth and clearance in constrained applications. Verify mechanical fit before substitution.

Q: What are the compliance implications of using the 4-102972-0-12?

A: The 4-102972-0-12 is RoHS non-compliant and carries Obsolete product status. Applications subject to RoHS3 regulations (EU Directive 2011/65/EU or equivalent) must not use this part. New designs must specify the TSW-112-15-G-S-LL or equivalent RoHS-compliant alternatives.

Q: Are there temperature rating differences between these parts?

A: Yes. The TSW-112-15-G-S-LL operates from -55°C to 125°C, while the 4-102972-0-12 operates from -65°C to 105°C. The TSW-112-15-G-S-LL provides higher maximum temperature capability. For applications exceeding 105°C, the TSW-112-15-G-S-LL is required.

Q: What is the significance of the contact finish thickness difference?

A: The 4-102972-0-12 has thicker gold plating on mating contacts (15.0µin vs. 10.0µin), which may provide enhanced wear resistance in high-cycle mating applications. However, both finishes meet standard connector durability requirements. This difference does not affect substitution eligibility for typical applications.

Q: Why is the contact length different between these parts?

A: The TSW-112-15-G-S-LL features longer mating contacts (0.520" vs. 0.318"), which may accommodate deeper mating receptacles or provide additional contact engagement. Verify receptacle depth specifications before substitution to ensure adequate contact engagement and retention.

Q: Is the 4-102972-0-12 still available for purchase?

A: The 4-102972-0-12 carries Obsolete product status, indicating discontinued manufacturing. Availability is limited to existing inventory. For new projects or long-term supply requirements, specify the TSW-112-15-G-S-LL or equivalent active-status alternatives.
