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

Part Overview

The TSW-112-15-L-S-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting 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 unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when addressing obsolescence concerns, supply chain constraints, or specific application requirements that align with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-15-L-S-LL is determined by strict alignment of the following parameters: connector type (Header), contact type (Male Pin), pitch (0.100" / 2.54mm), number of positions (12), number of rows (1), mounting type (Through Hole), and solder termination capability. The substitute part 4-102972-0-12 (TE Connectivity AMP Connectors) satisfies these core electrical and mechanical requirements. However, critical differences exist in product status, compliance certifications, and contact geometry that must be evaluated for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

The TSW-112-15-L-S-LL maintains Active product status with ROHS3 compliance, positioning it as the primary selection for new designs and applications requiring regulatory adherence. The 4-102972-0-12 substitute carries Obsolete product status and RoHS non-compliance, limiting its application to legacy system maintenance or retrofit scenarios where existing inventory must be utilized. Contact geometry differences—specifically the longer mating contact length (0.520" vs. 0.318") and greater insulation height (0.100" vs. 0.090") of the TSW-112-15-L-S-LL—may affect mechanical fit within existing connector receptacles. The operating temperature range of the TSW-112-15-L-S-LL (-55°C ~ 125°C) exceeds that of the substitute (-65°C ~ 105°C) at the upper limit, providing broader thermal performance capability. Selection between these parts must account for compliance requirements, physical space constraints, and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

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

A: Electrical and mechanical compatibility exists at the pitch (0.100" / 2.54mm), position count (12), and row configuration (1) level. However, differences in contact geometry, insulation height, and product status require evaluation against specific application requirements. The substitute's Obsolete status and RoHS non-compliance may restrict use in regulated environments.

Q: What are the key differences in contact dimensions?

A: The TSW-112-15-L-S-LL features a mating contact length of 0.520" (13.21mm) compared to 0.318" (8.08mm) for the 4-102972-0-12. Insulation height differs by 0.010" (0.25mm), with the TSW-112-15-L-S-LL measuring 0.100" (2.54mm). These dimensional variations may affect fit within existing receptacle designs.

Q: Are there compliance or certification differences?

A: The TSW-112-15-L-S-LL is ROHS3 compliant, while the 4-102972-0-12 is RoHS non-compliant. Both parts carry UL94 V-0 flammability ratings. The TSW-112-15-L-S-LL's Active product status ensures ongoing manufacturer support and availability, whereas the substitute's Obsolete status indicates discontinued production.

Q: How do the operating temperature ranges compare?

A: The TSW-112-15-L-S-LL operates across -55°C ~ 125°C, while the 4-102972-0-12 operates across -65°C ~ 105°C. The TSW-112-15-L-S-LL provides superior high-temperature performance, extending 20°C beyond the substitute's upper limit.

Q: What termination differences exist?

A: The TSW-112-15-L-S-LL uses kinked pin solder termination, while the 4-102972-0-12 uses standard solder termination. Both are solder-compatible for PCB assembly. The kinked pin design of the TSW-112-15-L-S-LL may provide enhanced mechanical retention during assembly.
