TSW-138-08-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-138-08-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 76-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 are identified when equivalent electrical and mechanical parameters align with application requirements, particularly when the original part becomes unavailable or when design flexibility permits alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-138-08-G-D-RA is determined by alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Type: Male Pin
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Style: Board to Board or Cable

The substitute part 4-103326-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares these core electrical and mechanical parameters. Variations in position count (80 vs. 76), contact finish thickness, insulation height, and operating temperature range represent acceptable deviations within the substitution framework, provided the application accommodates these differences.

Engineering Selection Recommendations

The TSW-138-08-G-D-RA maintains Active product status with full RoHS3 compliance and represents the primary selection for new designs. The substitute part 4-103326-0 carries Obsolete status and RoHS non-compliance, limiting its applicability to legacy system maintenance or applications where regulatory compliance is not required.

Selection between these parts depends on:

• Product lifecycle requirements: Active status (TSW-138-08-G-D-RA) is preferred for ongoing production and new designs.
• Regulatory compliance: RoHS3 compliance (TSW-138-08-G-D-RA) is mandatory for applications subject to EU directives or equivalent standards.
• Temperature operating range: TSW-138-08-G-D-RA supports -55°C to 125°C; 4-103326-0 supports -65°C to 105°C. Selection depends on specific thermal requirements.
• Position count: TSW-138-08-G-D-RA provides 76 positions; 4-103326-0 provides 80 positions. Design accommodation of additional positions is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can 4-103326-0 be used as a direct replacement for TSW-138-08-G-D-RA?

A: Substitution is possible only if the application accommodates the 80-position configuration (versus 76 positions), accepts the lower maximum operating temperature of 105°C, and does not require RoHS3 compliance. The core electrical and mechanical parameters—pitch, mounting type, termination, and contact type—are equivalent.

Q: What are the key differences between these connectors?

A: Primary differences include position count (76 vs. 80), operating temperature range (-55°C to 125°C vs. -65°C to 105°C), contact material (phosphor bronze vs. copper alloy), insulation material (PBT vs. thermoplastic), product status (Active vs. Obsolete), and regulatory compliance (RoHS3 compliant vs. non-compliant).

Q: Is the 4-position difference significant?

A: Yes. The 4-position difference affects PCB layout and connector footprint. The application must accommodate the larger 80-position header, or the substitute part is not suitable.

Q: Does the insulation height difference affect compatibility?

A: The insulation height difference (0.219" vs. 0.238") may affect board-to-board spacing and mating clearances. Design verification is required to confirm mechanical fit within the application.

Q: Why is 4-103326-0 marked as Obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by TE Connectivity. Availability is limited to existing inventory. TSW-138-08-G-D-RA is the recommended alternative for ongoing applications.

Q: Can these connectors be used in high-temperature applications?

A: TSW-138-08-G-D-RA supports -55°C to 125°C and is suitable for high-temperature applications within this range. 4-103326-0 supports -65°C to 105°C and is limited to lower maximum temperatures.
