TSW-115-07-S-D Equivalent & Substitute Parts

Part Overview

The TSW-115-07-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 30-position, 2-row connector operates across a wide temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the TSW-115-07-S-D 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-115-07-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 pin contacts
• Mounting Type: Through Hole solder termination
• Row configuration: 2-row layout with 0.100" row spacing
• Contact finish: Gold-plated mating surface with tin-plated posts
• Insulation material: PBT or equivalent thermoplastic
• Operating temperature range: Must support -55°C to 125°C minimum
• Flammability: UL94 V-0 rating required

The substitute part 4-103240-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the core electrical and mechanical characteristics necessary for functional equivalence, including identical pitch, connector type, mounting method, contact materials, and row spacing. However, differences in position count, insulation height, contact length specifications, and product status require engineering evaluation for specific applications.

Engineering Selection Recommendations

The TSW-115-07-S-D maintains active product status with full RoHS3 compliance and represents the primary selection for new designs. The part's extended upper operating temperature limit of 125°C and specified phosphor bronze contact material provide performance advantages for high-temperature applications.

The 4-103240-0 substitute carries obsolete product status and RoHS non-compliance, limiting its suitability to legacy system maintenance or applications where RoHS requirements do not apply. The substitute's reduced upper operating temperature limit of 105°C and tin-lead post finish present constraints for thermal-demanding environments. The 80-position configuration of the substitute exceeds the 30-position requirement of the main part, necessitating mechanical redesign or selective position loading.

For applications requiring active product support, regulatory compliance, and thermal performance within the -55°C to 125°C range, the TSW-115-07-S-D remains the specified selection. Substitution with 4-103240-0 is permissible only when legacy compatibility is mandatory and RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can the 4-103240-0 be used as a direct replacement for the TSW-115-07-S-D?

A: The 4-103240-0 shares identical pitch (0.100"), row spacing, connector type, and mounting method. However, the 80-position configuration versus 30-position, reduced insulation height (0.090" vs 0.100"), and obsolete product status require design verification. The substitute is functionally compatible for the mating interface but not a direct drop-in replacement due to position count and dimensional differences.

Q: What are the implications of the RoHS non-compliance status of the 4-103240-0?

A: RoHS non-compliance indicates the substitute contains restricted substances (lead in the tin-lead post finish). Applications subject to RoHS regulations, EU directives, or customer specifications requiring RoHS compliance must use the TSW-115-07-S-D. Legacy systems or non-regulated applications may accept the substitute.

Q: How do the operating temperature ranges differ between these parts?

A: The TSW-115-07-S-D operates from -55°C to 125°C, while the 4-103240-0 operates from -65°C to 105°C. The main part supports higher maximum temperatures (20°C advantage), making it suitable for thermal-demanding applications. The substitute provides lower minimum temperature capability but is limited at the upper range.

Q: What is the significance of the contact post length difference?

A: The TSW-115-07-S-D has 0.100" (2.54mm) post length versus 0.120" (3.05mm) for the 4-103240-0. This 0.020" difference affects PCB solder joint geometry and may require reflow profile adjustment. Verify PCB pad design and solder volume compatibility before substitution.

Q: Can the 80-position 4-103240-0 be used in a 30-position application?

A: The 4-103240-0 can be mechanically configured for 30-position use through selective loading or breakaway design. However, this requires design modification and verification of the breakaway mechanism compatibility with the application's mating connector.

Q: Are the contact materials interchangeable?

A: The TSW-115-07-S-D uses phosphor bronze contacts while the 4-103240-0 uses copper alloy. Both materials provide adequate conductivity and contact force for 2.54mm pitch applications. The phosphor bronze specification of the main part offers superior spring characteristics and wear resistance in high-cycle mating applications.
