Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-26-S-S is determined by the following critical parameters:

• Position Count & Pitch: 36 positions at 0.100" (2.54mm) mating pitch
• Connector Configuration: Single-row, unshrouded header with male pins
• Mounting & Termination: Through-hole solder termination
• Contact Geometry: Square contact shape with matching insulation height of 0.100" (2.54mm)
• Material Compliance: PBT insulation material, UL94 V-0 flammability rating, RoHS compliance

The substitute part 929647-09-36-I (3M) meets these core substitution criteria. Both parts share identical position count, pitch, mounting type, termination method, contact shape, insulation height, and material flammability classification. Both are active products with RoHS compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-136-26-S-S and 929647-09-36-I are active products with equivalent core mechanical and electrical compatibility for 36-position, 2.54mm pitch header applications. Selection between these parts should be based on the following factors derived from provided specifications:

Operating Temperature Range: The TSW-136-26-S-S supports -55°C to 125°C, while the 929647-09-36-I operates within -40°C to 105°C. Applications requiring extended low-temperature performance below -40°C or sustained operation above 105°C necessitate the Samtec part.

Contact Material & Finish: The TSW-136-26-S-S uses phosphor bronze contacts with tin-plated posts and 30.0µin gold mating finish. The 929647-09-36-I employs copper alloy contacts with gold plating on both mating and post surfaces (10.0µin thickness). Contact material selection depends on application-specific corrosion resistance and conductivity requirements.

Insulation Material Composition: The 929647-09-36-I specifies glass-filled polyester in addition to PBT, providing enhanced mechanical properties. The TSW-136-26-S-S uses standard PBT insulation.

Compliance & Certifications: Both parts are RoHS compliant, UL94 V-0 rated, and carry MSL 1 moisture sensitivity classification. Both are REACH unaffected and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the 929647-09-36-I directly replace the TSW-136-26-S-S in existing designs?

A: Direct mechanical and electrical substitution is supported for applications operating within the 929647-09-36-I temperature range (-40°C to 105°C). The 36-position, 2.54mm pitch configuration, through-hole solder termination, and contact geometry are identical. Verify that your application does not require the extended low-temperature performance of the TSW-136-26-S-S (-55°C minimum).

Q: What are the differences in contact finish specifications?

A: The TSW-136-26-S-S provides 30.0µin (0.76µm) gold on mating contacts and tin plating on posts. The 929647-09-36-I provides 10.0µin (0.25µm) gold on both mating and post contacts. Both finishes meet gold plating standards for connector applications; the difference reflects manufacturing process variation between manufacturers.

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

A: Both parts carry UL94 V-0 flammability ratings, RoHS compliance, and MSL 1 moisture sensitivity classification, indicating suitability for standard industrial and commercial applications. Specific high-reliability requirements should be evaluated against detailed application specifications and environmental conditions.

Q: What is the significance of the "Breakaway" designation on the 3M part?

A: The 929647-09-36-I is classified as a breakaway header, indicating the connector supports segmentation or partial removal of positions. This feature does not affect compatibility with standard 36-position mating applications but provides design flexibility for applications requiring modular connector configurations.

Q: How do the insulation materials compare?

A: The TSW-136-26-S-S uses standard PBT insulation. The 929647-09-36-I specifies PBT with glass-filled polyester, which provides enhanced mechanical strength and dimensional stability. Both materials meet UL94 V-0 flammability requirements and are suitable for standard connector applications.
