TSW-122-17-S-D Equivalent & Substitute Parts

Part Overview

The TSW-122-17-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical header features 44 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The part is currently active in production with 1069 units in stock. Alternative models may be required due to inventory constraints, specific insulation material requirements, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-122-17-S-D is determined by the following critical parameters:

• Connector type (Header)
• Number of positions (44)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm mating and row spacing)
• Mounting type (Through Hole)
• Contact type (Male Pin)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, UL94 V-0)

The HTSW-122-17-S-D meets all these criteria and qualifies as a direct substitute. Variations in insulation material (PBT versus LCP) and insulation color do not affect electrical or mechanical compatibility when all other parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The HTSW-122-17-S-D is a qualified substitute for the TSW-122-17-S-D. Both parts are manufactured by Samtec Inc., maintain identical electrical and mechanical specifications, and carry equivalent compliance certifications (ROHS3 Compliant, UL94 V-0). The primary difference is the insulation material composition: PBT in the TSW-122-17-S-D versus LCP in the HTSW-122-17-S-D. Both materials meet the same flammability and temperature performance requirements. Selection between these parts should be based on application-specific material requirements, inventory availability, or design specifications that mandate a particular insulation material.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-122-17-S-D be used as a direct replacement for the TSW-122-17-S-D?

A: Yes. Both parts share identical connector type, position count, pitch spacing, mounting configuration, contact specifications, and operating temperature range. The insulation material difference (PBT versus LCP) does not affect mechanical or electrical compatibility.

Q: What is the difference between PBT and LCP insulation materials in these connectors?

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both thermoplastic materials that meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C ~ 125°C). Material selection depends on specific application requirements such as dimensional stability, chemical resistance, or moisture absorption characteristics.

Q: Are the contact specifications identical between these two parts?

A: Yes. Both parts feature identical contact length (mating: 0.620", post: 0.110"), contact shape (square), contact material (phosphor bronze), and contact finish specifications (gold mating surface at 30.0µin thickness, tin post finish).

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both the TSW-122-17-S-D and HTSW-122-17-S-D are ROHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What determines substitution eligibility for these rectangular connectors?

A: Substitution is determined by matching connector type, position count, row configuration, pitch spacing, mounting type, contact type, operating temperature range, and compliance certifications. Variations in insulation material or color do not affect substitution eligibility when all other parameters remain constant.
