TSW-105-23-L-S-LL Equivalent & Substitute Parts

Part Overview

The TSW-105-23-L-S-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 5-position, 0.100" (2.54mm) pitch connector serves board-to-board and cable interconnection requirements. The part is currently active in production status. Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or design revision requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-105-23-L-S-LL is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 5 — determines circuit connectivity
• Number of Rows: 1 — defines physical layout
• Contact Type: Male Pin — ensures proper mating interface
• Mounting Type: Through Hole — required for PCB assembly compatibility
• Connector Type: Header — functional classification
• Contact Finish - Mating: Gold — ensures signal integrity and corrosion resistance

The substitute parts 4-103185-0-05 and 5-146280-5, both manufactured by TE Connectivity AMP Connectors, satisfy these core parameters. Both are 5-position, 1-row, 0.100" pitch male pin headers with through-hole mounting and gold-plated mating contacts.

Engineering Selection Recommendations

5-146280-5 (TE Connectivity) is the preferred substitute for new designs and applications requiring RoHS compliance. This part maintains active product status, carries RoHS Compliant certification, and provides full compatibility with the TSW-105-23-L-S-LL across all critical mating parameters. The operating temperature range of -65°C ~ 105°C covers the majority of standard industrial applications, with the upper limit being 20°C lower than the original part.

4-103185-0-05 (TE Connectivity) is suitable only for legacy system maintenance or applications where RoHS compliance is not required. This part carries obsolete product status and RoHS non-compliant certification, making it unsuitable for new production designs or regulated applications.

Both substitute parts exhibit minor dimensional variations in contact post length (0.120" versus 0.115") and insulation height (0.090" versus 0.100"), which remain within acceptable mechanical tolerances for standard through-hole PCB assembly. The difference in contact finish thickness on mating surfaces (15.0µin versus 10.0µin) provides enhanced durability in the substitute parts.

Frequently Asked Questions (FAQ)

Q: Can 5-146280-5 be used as a direct replacement for TSW-105-23-L-S-LL in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (5), row configuration (1), contact type (male pin), and mounting method (through-hole). The mechanical and electrical interfaces are compatible. Minor dimensional differences in post length and insulation height do not affect PCB assembly or mating performance.

Q: What is the significance of the operating temperature range difference?

A: The TSW-105-23-L-S-LL operates from -55°C to 125°C, while 5-146280-5 operates from -65°C to 105°C. The substitute part provides lower temperature capability but has a 20°C lower upper limit. Applications requiring operation above 105°C must use the original Samtec part.

Q: Why is 4-103185-0-05 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While the part may remain available through inventory channels, it is not recommended for new designs due to supply uncertainty and lack of ongoing manufacturer support.

Q: Does the difference in insulation material affect compatibility?

A: No. The TSW-105-23-L-S-LL uses PBT, while 5-146280-5 uses LCP. Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation properties for standard applications. Material selection affects mechanical and thermal characteristics but not mating interface compatibility.

Q: What is the impact of RoHS compliance status?

A: RoHS3 compliance (TSW-105-23-L-S-LL) and RoHS Compliance (5-146280-5) indicate restriction of hazardous substances in accordance with EU regulations. The non-compliant 4-103185-0-05 may contain lead or other restricted materials. Applications subject to RoHS requirements must use compliant parts.

Q: Are there differences in contact finish that affect signal integrity?

A: Both parts use gold-plated mating contacts. The substitute parts have thicker gold plating (15.0µin versus 10.0µin), which provides enhanced corrosion resistance and contact durability. This difference improves rather than compromises signal integrity.
