Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-105-08-G-D-LA and 826634-5 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. The primary differences affecting selection are:

Contact geometry and material composition differ between the two parts. The HTSW-105-08-G-D-LA uses phosphor bronze contacts with gold plating on both mating and post surfaces, while the 826634-5 uses brass contacts with gold mating finish and tin post finish. The HTSW part provides thicker gold plating on the mating surface (10.0µin versus 3.90µin).

Operating temperature ranges differ. The HTSW-105-08-G-D-LA operates from -55°C to 125°C, while the 826634-5 operates from -65°C to 105°C. Selection depends on the specific thermal requirements of the application.

Insulation materials differ. The HTSW-105-08-G-D-LA uses Liquid Crystal Polymer (LCP), while the 826634-5 uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 requirements.

The 826634-5 includes a breakaway feature not present in the HTSW-105-08-G-D-LA, which may provide additional design flexibility for modular applications.

Frequently Asked Questions (FAQ)

Q: Can the 826634-5 be used as a direct replacement for the HTSW-105-08-G-D-LA?

A: The 826634-5 is mechanically and electrically compatible based on pitch, position count, row spacing, mounting type, and fastening mechanism. However, differences in contact materials, plating thickness, operating temperature ranges, and insulation materials must be evaluated against specific application requirements before substitution.

Q: What are the key differences in contact construction?

A: The HTSW-105-08-G-D-LA uses phosphor bronze with gold plating on both mating and post surfaces. The 826634-5 uses brass with gold mating finish and tin post finish. The HTSW part provides thicker gold plating on the mating surface (10.0µin versus 3.90µin), which may provide enhanced corrosion resistance in certain environments.

Q: How do the operating temperature ranges differ?

A: The HTSW-105-08-G-D-LA operates from -55°C to 125°C, providing a higher upper temperature limit. The 826634-5 operates from -65°C to 105°C, providing a lower minimum temperature. Application thermal requirements determine which part is appropriate.

Q: Are both parts RoHS compliant?

A: Yes, both the HTSW-105-08-G-D-LA and 826634-5 are ROHS3 compliant and carry UL94 V-0 flammability ratings.

Q: What is the significance of the breakaway feature on the 826634-5?

A: The 826634-5 includes a breakaway feature, allowing individual positions to be separated if needed. The HTSW-105-08-G-D-LA does not include this feature. This may provide design flexibility for applications requiring modular connector configurations.

Q: Do the different insulation materials affect compatibility?

A: The HTSW-105-08-G-D-LA uses Liquid Crystal Polymer (LCP), while the 826634-5 uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. Material selection may affect mechanical properties, chemical resistance, and thermal performance in specific environments.

Q: What is the difference in contact length?

A: The HTSW-105-08-G-D-LA has a mating contact length of 0.230" (5.84mm) and post contact length of 0.090" (2.29mm). The 826634-5 has a mating contact length of 0.264" (6.70mm) and post contact length of 0.126" (3.20mm). These differences may affect mating depth and PCB pad design considerations.

Q: Are moisture sensitivity levels the same?

A: Yes, both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
