TSW-134-08-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-134-08-G-D-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 68-position connector operates across a wide temperature range of -55°C to 125°C and features gold-plated phosphor bronze contacts with PBT insulation rated UL94 V-0. The part maintains active product status with full RoHS3 compliance and MSL Level 1 rating. Substitute parts may be required due to inventory constraints, design revisions, or application-specific compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-134-08-G-D-RA is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Mounting Type: Through Hole, Right Angle — connector orientation and installation method must be identical
• Contact Type: Male Pin — gender compatibility is non-negotiable
• Number of Rows: 2 — row configuration must align with PCB layout
• Termination: Solder — connection method must be compatible with assembly process
• Operating Temperature Range: Must encompass or match the application requirement
• Contact Finish - Mating: Gold — electrical performance and corrosion resistance requirements
• RoHS Compliance: Application-dependent regulatory requirement

The substitute part 4-103326-0 (TE Connectivity AMP Connectors) shares the core mechanical and electrical parameters but introduces variations in position count, contact geometry, and compliance status that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-134-08-G-D-RA is the primary selection for new designs due to its active product status and full RoHS3 compliance. The substitute part 4-103326-0 presents the following considerations:

Position Count Variance: The substitute accommodates 80 positions versus 68 in the main part. This difference requires PCB layout verification to confirm mechanical fit and electrical routing compatibility.

Temperature Operating Range: The main part supports -55°C to 125°C, while the substitute operates within -65°C to 105°C. Applications requiring the full upper temperature range of the main part cannot use the substitute without thermal analysis.

Compliance Status: The main part is RoHS3 compliant and active. The substitute is obsolete and RoHS non-compliant, making it unsuitable for new designs subject to regulatory requirements or long-term supply chain planning.

Contact Post Length: The substitute features a longer post (0.120" vs. 0.090"), resulting in increased insulation height (0.238" vs. 0.219"). PCB clearance and mating connector depth must be verified.

Contact Material: The main part uses phosphor bronze; the substitute uses copper alloy. This material difference may affect contact resistance and mechanical durability characteristics.

Frequently Asked Questions (FAQ)

Q: Can 4-103326-0 be used as a direct replacement for TSW-134-08-G-D-RA?

A: Direct replacement is not recommended. While both connectors share 0.100" (2.54mm) pitch, through-hole right-angle mounting, and 2-row configuration, the 80-position versus 68-position count difference requires PCB layout verification. Additionally, the substitute's obsolete status and RoHS non-compliance make it unsuitable for new designs.

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

A: Pitch (0.100" / 2.54mm), mounting type (through-hole right-angle), contact type (male pin), number of rows (2), and termination method (solder) must remain constant. Deviations in these parameters will result in mechanical or electrical incompatibility.

Q: Does the longer contact post on 4-103326-0 affect compatibility?

A: Yes. The post length difference (0.120" vs. 0.090") increases overall insulation height from 0.219" to 0.238". This affects mating connector depth and PCB clearance. Verification against mating connector specifications is required.

Q: Is the operating temperature range difference significant?

A: The main part supports -55°C to 125°C; the substitute supports -65°C to 105°C. Applications requiring operation above 105°C cannot use the substitute. The lower minimum temperature of the substitute (-65°C vs. -55°C) is not a limiting factor for most applications.

Q: Why is RoHS compliance important for this substitution?

A: RoHS3 compliance is mandatory for products sold in regulated markets. The main part is compliant; the substitute is not. New designs must use RoHS-compliant components. Existing legacy systems may use non-compliant parts, but this limits future supply chain options.

Q: Can the 80-position substitute be used in a 68-position application?

A: The substitute has additional positions but maintains the same pitch and row spacing. If the PCB layout accommodates the extra positions without electrical conflicts, the substitute may function. However, this requires explicit design verification and is not a standard substitution practice.
