TSW-123-07-T-S Equivalent & Substitute Parts

Part Overview

The TSW-123-07-T-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 23-position, single-row connector operates at 0.100" (2.54mm) pitch and is rated for operating temperatures from -55°C to 105°C. The part maintains Active product status with full inventory availability. Substitute parts are identified to address specific application requirements where position count, contact specifications, or product lifecycle considerations necessitate alternative component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-123-07-T-S 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 pin contact configuration
• Mounting Type: Through Hole solder termination
• Material Flammability Rating: UL94 V-0 compliance required
• RoHS Status: ROHS3 Compliant

The substitute part 4-103327-9 (TE Connectivity AMP Connectors) shares these core electrical and mechanical characteristics. However, it differs in position count (40 positions versus 23 positions), insulation height (0.090" versus 0.100"), and contact post length (0.120" versus 0.100"). These differences require evaluation based on specific application constraints and available board space.

Parameter Comparison

Engineering Selection Recommendations

The TSW-123-07-T-S maintains Active product status with established supply chain availability. The substitute part 4-103327-9 carries Obsolete product status, indicating discontinued manufacturing and potential long-term supply constraints.

Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance standards. The substitute part provides an extended operating temperature range (-65°C versus -55°C minimum), which may be advantageous in extreme cold environments.

Selection between these parts should prioritize the Active status of the TSW-123-07-T-S for new designs requiring long-term component availability. The substitute part 4-103327-9 is suitable only for legacy system maintenance or applications where the 40-position configuration and Obsolete status present no supply or lifecycle concerns.

Frequently Asked Questions (FAQ)

Q: Can the 4-103327-9 substitute directly for the TSW-123-07-T-S in existing designs?

A: Direct substitution is not recommended without design review. The substitute part has 40 positions versus 23 positions, requiring PCB layout modification. The insulation height differs by 0.010" (0.25mm), which may affect mating clearances.

Q: What is the significance of the Obsolete product status for the substitute part?

A: Obsolete status indicates the manufacturer has discontinued production. This creates supply risk for future procurement and may result in higher costs or unavailability. New designs should specify the Active TSW-123-07-T-S.

Q: Are the contact materials interchangeable?

A: Both parts use tin-plated contacts suitable for solder termination. The TSW-123-07-T-S uses phosphor bronze; the substitute uses copper alloy. Both materials are acceptable for standard through-hole applications within the specified operating temperature ranges.

Q: Does the substitute part's extended temperature range (-65°C minimum) provide compatibility advantages?

A: The extended range is a superset of the main part's range. The substitute part is compatible with applications requiring -55°C to 105°C operation. However, this advantage is offset by Obsolete product status and position count differences.

Q: What packaging considerations apply to these connectors?

A: Both parts are through-hole solder-terminated headers with 0.100" (2.54mm) pitch. PCB footprint compatibility depends on position count matching. The substitute's 40-position configuration requires different board layout than the 23-position main part.
