TSW-126-26-S-S Equivalent & Substitute Parts

Part Overview

The TSW-126-26-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 26-position vertical header operates within the -55°C to 125°C temperature range and features gold-plated mating contacts with tin-plated posts. The connector maintains Active product status and is fully RoHS3 compliant, making it suitable for modern electronic assemblies requiring standard 0.100" (2.54mm) pitch interconnection.

Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-126-26-S-S is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 26
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as direct equivalents. Deviations in any parameter disqualify a part from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The TSW-126-26-S-S maintains Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. These certifications ensure suitability for contemporary electronic assemblies subject to environmental and regulatory requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Selection of equivalent parts should prioritize components with identical Active status and matching compliance certifications to ensure long-term supply availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: What defines a direct equivalent for the TSW-126-26-S-S? A: A direct equivalent must match all critical parameters: 26-position, single-row header with 0.100" (2.54mm) pitch, through-hole solder termination, gold mating contacts with tin posts, PBT insulation, UL94 V-0 rating, and ROHS3 compliance.

Q: Can connectors with different pitch specifications substitute for the TSW-126-26-S-S? A: No. The 0.100" (2.54mm) pitch is a fundamental mechanical parameter. Connectors with alternative pitch specifications are not compatible with mating receptacles designed for this part.

Q: Are there compatibility considerations for PCB layout when using substitute parts? A: Substitute parts meeting all specified parameters maintain identical footprint and mounting characteristics. PCB layout modifications are not required when using qualified equivalents.

Q: What is the significance of the contact finish specifications? A: Gold plating on mating contacts provides corrosion resistance and reliable electrical contact. Tin plating on posts ensures solderability. These finishes are integral to the connector's performance specification and must be maintained in any substitute part.

Q: Does the UL94 V-0 rating affect substitute part selection? A: Yes. The UL94 V-0 flammability rating is a compliance requirement for many applications. Substitute parts must maintain this certification to ensure regulatory compliance and safety performance.
