TSW-134-14-S-S Equivalent & Substitute Parts

Part Overview

The TSW-134-14-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 34-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status with full inventory availability. Substitute parts become necessary when addressing specific application requirements such as position count variations, operating temperature ranges, or component availability constraints while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-134-14-S-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must remain constant for PCB footprint compatibility
• Connector Type: Header with male pin contacts for board-to-board or cable applications
• Mounting Type: Through-hole solder termination
• Contact Finish: Gold mating surface with tin post finish
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Minimum -55°C ~ 125°C or broader
• Flammability Rating: UL94 V-0 compliance
• RoHS Compliance: ROHS3 or equivalent

The substitute part 4-102976-0 (TE Connectivity AMP Connectors) presents a position count variation (40 positions versus 34 positions) while maintaining core electrical and mechanical compatibility across pitch, contact type, mounting method, and termination specifications. This substitution is valid for applications where the increased position count does not create physical or electrical conflicts with the target PCB layout.

Parameter Comparison

Engineering Selection Recommendations

The TSW-134-14-S-S maintains Active product status with ROHS3 compliance, making it the preferred choice for new designs and applications requiring current regulatory adherence. The substitute part 4-102976-0 carries Obsolete status and lacks RoHS compliance documentation, limiting its suitability to legacy system maintenance or applications where regulatory compliance is not a requirement.

Key differentiation factors include operating temperature range (TSW-134-14-S-S: -55°C ~ 125°C versus 4-102976-0: -65°C ~ 105°C) and contact post finish (tin versus tin-lead). The substitute part's breakaway feature and increased position count (40 versus 34) may introduce mechanical or electrical incompatibilities depending on target PCB layout constraints.

For applications requiring active product status, RoHS3 compliance, and extended high-temperature operation, the TSW-134-14-S-S is the appropriate selection. The 4-102976-0 substitute is applicable only when position count expansion is acceptable and regulatory compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can the 4-102976-0 be used as a direct replacement for the TSW-134-14-S-S?

A: Direct replacement is not recommended. While both connectors share identical 0.100" (2.54mm) pitch, single-row configuration, and through-hole solder termination, the substitute part features 40 positions compared to 34 positions. PCB footprint compatibility must be verified before substitution. Additionally, the substitute part is Obsolete and lacks RoHS3 compliance.

Q: What are the critical parameters that must match for substitution?

A: Pitch (0.100" / 2.54mm), connector type (header with male pins), mounting method (through-hole), termination (solder), contact finish (gold mating / tin post), and insulation material (PBT or thermoplastic) must remain consistent. Operating temperature range and flammability rating should meet or exceed application requirements.

Q: Does the position count difference affect electrical performance?

A: Position count does not directly affect electrical performance of individual contacts. However, the increased physical length of the 40-position connector may create mechanical conflicts with PCB layout, component placement, or enclosure constraints. Dimensional verification is required.

Q: Are there compliance differences between these parts?

A: Yes. The TSW-134-14-S-S is ROHS3 compliant with Active product status. The 4-102976-0 is marked Obsolete with RoHS status listed as Not applicable, indicating it predates current regulatory requirements. New designs should prioritize the TSW-134-14-S-S.

Q: What is the significance of the breakaway feature on the substitute part?

A: The breakaway feature on the 4-102976-0 allows individual positions to be separated from the connector body. This feature is not present on the TSW-134-14-S-S. Breakaway capability may be beneficial for modular applications but introduces design differences that require application-specific evaluation.

Q: How do the operating temperature ranges compare?

A: The TSW-134-14-S-S operates from -55°C to 125°C, providing superior high-temperature performance. The 4-102976-0 operates from -65°C to 105°C, offering lower minimum temperature capability but reduced maximum temperature rating. Application thermal requirements must be verified against each part's range.
