TSW-134-07-S-D Equivalent & Substitute Parts

Part Overview

The TSW-134-07-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical header features 68 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is currently in active production status with gold-plated mating contacts and tin-plated posts, operating across a temperature range of -55°C to 125°C.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-134-07-S-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Connector Type: Header with male pins — functional requirement for board-to-board connection
• Mounting Type: Through Hole — PCB assembly process compatibility
• Termination: Solder — assembly method compatibility
• Row Spacing - Mating: 0.100" (2.54mm) — mechanical fit requirement

The substitute part 4-103240-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares these critical parameters. However, variations exist in position count (80 vs. 68), insulation height (0.090" vs. 0.100"), contact post length (0.120" vs. 0.100"), and product status (Obsolete vs. Active). These differences require engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-134-07-S-D maintains active production status with ROHS3 compliance and an unlimited moisture sensitivity level (MSL 1), making it the preferred choice for new designs and ongoing production requirements.

The substitute part 4-103240-0 is classified as obsolete and does not meet RoHS compliance requirements. This part should be considered only in legacy system maintenance scenarios where exact form-factor compatibility with existing designs is mandatory and where RoHS non-compliance is acceptable under application-specific regulatory conditions.

Key differentiators affecting selection:

• Position count difference (68 vs. 80) requires PCB footprint verification
• Operating temperature range reduction (-55°C to 125°C vs. -65°C to 105°C) must be evaluated against application thermal requirements
• Contact post length variation (0.100" vs. 0.120") affects PCB stack-up compatibility
• Insulation height difference (0.100" vs. 0.090") impacts mechanical clearance in confined spaces
• Contact finish post material change (Tin vs. Tin-Lead) affects solderability characteristics

Frequently Asked Questions (FAQ)

Q: Can the 4-103240-0 be used as a direct replacement for the TSW-134-07-S-D?

A: Direct replacement is not recommended. While both connectors share the same 0.100" (2.54mm) pitch and basic header configuration, the 4-103240-0 has 80 positions compared to 68 positions in the TSW-134-07-S-D. PCB footprint compatibility must be verified before substitution. Additionally, the obsolete status and RoHS non-compliance of the 4-103240-0 present supply chain and regulatory risks.

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

A: The following parameters must remain constant for mechanical and electrical compatibility: mating pitch (0.100" / 2.54mm), connector type (header), contact type (male pin), mounting type (through hole), termination method (solder), and row spacing (0.100" / 2.54mm). Variations in position count, contact post length, insulation height, and operating temperature range require engineering evaluation specific to the application.

Q: Does the difference in operating temperature range affect compatibility?

A: The TSW-134-07-S-D operates from -55°C to 125°C, while the 4-103240-0 operates from -65°C to 105°C. If the application requires operation above 105°C or below -65°C, the substitute part cannot be used. Applications operating within the -55°C to 105°C window may be compatible, subject to other parameter verification.

Q: What is the significance of the RoHS compliance difference?

A: The TSW-134-07-S-D is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations. The 4-103240-0 is RoHS non-compliant. For applications subject to RoHS requirements or for export to regulated markets, only ROHS3-compliant parts are acceptable. The TSW-134-07-S-D is the only viable option for such applications.

Q: How does the position count difference affect PCB design?

A: The TSW-134-07-S-D has 68 positions (34 per row) while the 4-103240-0 has 80 positions (40 per row). The footprint dimensions and hole spacing will differ. PCB layout files must be verified for compatibility before any substitution. A connector with more positions cannot be used on a PCB designed for fewer positions without redesign.
