Substitute Part Grouping Explanation

Substitution eligibility for the TSW-131-08-G-S-RA is determined by alignment of the following critical parameters:

  • Pitch - Mating: 0.100" (2.54mm) — ensures mechanical and electrical compatibility with mating connectors
  • Connector Type: Header with Male Pin contacts — maintains board-to-board or cable interface functionality
  • Mounting Type: Through Hole, Right Angle — preserves PCB assembly method and spatial orientation
  • Termination: Solder — ensures compatibility with standard PCB assembly processes
  • Contact Finish: Gold plating — maintains electrical performance and corrosion resistance
  • Material Flammability Rating: UL94 V-0 — meets safety and regulatory requirements
  • RoHS Compliance: ROHS3 or equivalent — ensures regulatory alignment

The identified substitute part 9-103325-0 shares these core parameters. However, differences exist in position count (40 vs. 31), operating temperature range, contact material composition, and specific contact dimensions. These differences must be evaluated against application-specific requirements.

Engineering Selection Recommendations

Both the TSW-131-08-G-S-RA and 9-103325-0 maintain Active product status and meet UL94 V-0 flammability requirements with MSL 1 ratings. Both are RoHS compliant and suitable for standard PCB assembly processes.

Selection between these parts depends on application-specific constraints:

The TSW-131-08-G-S-RA operates across -55°C to 125°C and provides 31 positions with phosphor bronze contacts. This configuration is appropriate for applications requiring extended high-temperature performance.

The 9-103325-0 operates across -65°C to 105°C and provides 40 positions with copper alloy contacts and breakaway capability. This configuration is appropriate for applications requiring extended low-temperature performance and higher position density, provided the reduced upper temperature limit is acceptable.

Position count mismatch (31 vs. 40) requires verification that the application can accommodate the substitute's additional positions or that excess positions can be left unloaded without affecting functionality.

Frequently Asked Questions (FAQ)

Q: Can the 9-103325-0 directly replace the TSW-131-08-G-S-RA?

A: Direct replacement is possible only if the application accommodates the 40-position configuration and the operating temperature range of -65°C to 105°C. The 31-position requirement of the original part is not met by the 40-position substitute.

Q: What is the significance of the 0.100" (2.54mm) pitch specification?

A: Pitch determines the spacing between adjacent contacts and is critical for mechanical and electrical compatibility with mating connectors. Both parts share this specification, ensuring compatibility with standard 2.54mm pitch receptacles and cables.

Q: How do the contact materials differ between these parts?

A: The TSW-131-08-G-S-RA uses phosphor bronze contacts, while the 9-103325-0 uses copper alloy contacts. Both are gold-plated for corrosion resistance. Material selection affects mechanical properties and contact durability under repeated mating cycles.

Q: What does the breakaway feature on the 9-103325-0 provide?

A: The breakaway feature allows individual positions to be separated from the connector body, enabling custom configurations. The TSW-131-08-G-S-RA does not offer this capability.

Q: Are both parts suitable for high-temperature applications?

A: The TSW-131-08-G-S-RA supports operation to 125°C, making it suitable for higher-temperature environments. The 9-103325-0 is rated to 105°C maximum, limiting its use in applications exceeding this temperature.

Q: Do both parts meet current industry compliance standards?

A: Both parts are RoHS compliant and UL94 V-0 rated. The TSW-131-08-G-S-RA carries ROHS3 compliance, while the 9-103325-0 carries RoHS compliance. Both maintain MSL 1 ratings and REACH Unaffected status.
