TSW-130-07-S-S Equivalent & Substitute Parts

Part Overview

The TSW-130-07-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 30-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status with full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this connector category, enabling direct functional replacement in board-to-board or cable applications.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-130-07-S-S is determined by alignment of the following critical parameters:

Pitch - Mating: 0.100" (2.54mm)
Connector Type: Header with male pin contacts
Mounting Type: Through Hole
Termination: Solder
Contact Finish - Mating: Gold plating
Insulation Material: Thermoplastic or equivalent
Material Flammability Rating: UL94 V-0
Operating Temperature Range: Minimum -55°C, Maximum 125°C or greater

The substitute part 4-103747-0 (TE Connectivity AMP Connectors) shares these core electrical and mechanical parameters. However, differences exist in position count (40 vs. 30), contact post length, insulation height, and operating temperature range. These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

The TSW-130-07-S-S maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it the preferred choice for new designs and ongoing production. The substitute part 4-103747-0 carries Obsolete product status and lacks RoHS compliance documentation, limiting its suitability for applications requiring regulatory compliance or long-term supply assurance.

Selection between these parts must account for the following documented differences:

Position count variance (30 vs. 40) requires board layout compatibility verification. The substitute part features a reduced operating temperature maximum (105°C vs. 125°C), which may restrict use in high-temperature applications. Contact post length and insulation height differences (0.100" vs. 0.090") affect PCB footprint compatibility and stacking height calculations. The substitute part uses Tin-Lead post finish, which may conflict with lead-free manufacturing requirements in RoHS-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 4-103747-0 directly replace the TSW-130-07-S-S in existing designs?

A: Direct replacement is not recommended without design verification. The 40-position configuration of the substitute part exceeds the 30-position requirement of the main part. Contact post length and insulation height differences require PCB footprint re-evaluation. The Obsolete status of the substitute part presents supply chain risk.

Q: What are the critical compatibility factors for this connector category?

A: Pitch (0.100" / 2.54mm), contact type (male pin), mounting method (through hole), and termination type (solder) must remain constant. Position count, contact post length, and insulation height must align with PCB design specifications. Operating temperature range and flammability rating must meet application requirements.

Q: Does the substitute part meet RoHS requirements?

A: The 4-103747-0 carries "Not applicable" RoHS status, indicating it does not comply with ROHS3 standards. The main part TSW-130-07-S-S is ROHS3 compliant. Applications requiring RoHS compliance must use the main part or identify an alternative substitute with documented RoHS compliance.

Q: What is the impact of the contact post finish difference?

A: The main part uses Tin post finish; the substitute uses Tin-Lead. Tin-Lead finishes are restricted in lead-free manufacturing environments. This difference affects soldering process compatibility and regulatory compliance in applications subject to lead-free requirements.

Q: How do the operating temperature ranges compare?

A: The main part operates from -55°C to 125°C. The substitute part operates from -65°C to 105°C. The substitute part has a lower maximum temperature rating, restricting use in applications requiring sustained operation above 105°C.
