TSW-103-23-L-S-LL Equivalent & Substitute Parts

Part Overview

The TSW-103-23-L-S-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 3-position, single-row header connector operates at 0.100" (2.54mm) pitch and features kinked pin solder termination with push-pull fastening. The connector is classified as Active product status and complies with ROHS3 standards. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring compatible 3-position header connectors with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-23-L-S-LL is determined by strict alignment of the following parameters:

• Connector Type: Header (with or without breakaway feature)
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 3
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Material: PBT or LCP
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5-146280-3 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Minor variations in contact length specifications, insulation height, and operating temperature range do not preclude functional equivalence in standard through-hole header applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-23-L-S-LL and 5-146280-3 are Active product status connectors with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• PCB design constraints: The TSW-103-23-L-S-LL features a 0.100" (2.54mm) insulation height, while the 5-146280-3 has a 0.090" (2.29mm) insulation height. Applications with tight vertical clearance may benefit from the TE Connectivity option.
• Temperature requirements: The TSW-103-23-L-S-LL operates to 125°C maximum, while the 5-146280-3 operates to 105°C maximum. High-temperature applications above 105°C require the Samtec part.
• Contact post length: The 5-146280-3 provides 0.120" (3.05mm) post length versus 0.115" (2.92mm) for the TSW-103-23-L-S-LL, offering marginally greater solder joint engagement.
• Insulation material: The TSW-103-23-L-S-LL uses PBT, while the 5-146280-3 uses LCP. Both materials meet UL94 V-0 requirements.
• Breakaway feature: The 5-146280-3 includes a breakaway option, enabling individual position separation if required by application design.

Frequently Asked Questions (FAQ)

Q: Can the 5-146280-3 directly replace the TSW-103-23-L-S-LL on existing PCBs?

A: Yes, for applications operating within the 5-146280-3 temperature range (-65°C to 105°C). The 0.100" (2.54mm) pitch, 3-position single-row configuration, through-hole mounting, and push-pull fastening are identical. Minor dimensional variations in insulation height (0.090" vs 0.100") and contact post length (0.120" vs 0.115") do not affect mechanical fit or electrical performance in standard applications.

Q: What are the key electrical compatibility factors?

A: Both connectors feature gold-plated mating contacts, tin-plated posts, square contact geometry, and identical pitch spacing. The 5-146280-3 specifies a 3A current rating; the TSW-103-23-L-S-LL does not specify current rating. Both connectors support push-pull fastening and solder termination. Voltage ratings are not specified for either part.

Q: Are there temperature-related substitution limitations?

A: Yes. The TSW-103-23-L-S-LL operates from -55°C to 125°C, while the 5-146280-3 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the TSW-103-23-L-S-LL. Applications requiring operation below -55°C can use the 5-146280-3.

Q: What is the significance of the breakaway feature on the 5-146280-3?

A: The AMPMODU Mod II series includes a breakaway feature, allowing individual positions to be separated if required by application design. The TSW-103-23-L-S-LL does not include this feature. This does not affect substitution for standard applications where the full 3-position header is required.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSW-103-23-L-S-LL and 5-146280-3 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.

Q: What packaging considerations apply to these connectors?

A: Both parts are supplied in Bulk packaging. The TSW-103-23-L-S-LL has 786 pieces in stock; the 5-146280-3 has 275,691 pieces in stock. Procurement decisions may consider inventory availability and lead time requirements.
