Engineering Selection Recommendations

Both the MTSW-106-08-G-D-240 and 929665-02-06-I are active production parts with UL94 V-0 flammability certification and RoHS compliance. Selection between these parts depends on application-specific constraints:

MTSW-106-08-G-D-240 (Samtec) is suitable for applications requiring extended operating temperature range (-55°C to 125°C) and higher current capacity (3A). This part supports cuttable header configurations and is optimized for demanding thermal environments.

929665-02-06-I (3M) is suitable for applications operating within -40°C to 105°C temperature range with current requirements up to 2.5A. This part features PBT insulation material in addition to polyester and offers higher post contact length (0.210" vs 0.190"), which may provide improved solder joint reliability in certain PCB thickness applications.

Both parts share identical mating pitch (0.100"), row spacing (0.100"), contact finish specifications (10.0µin gold), and flammability ratings, ensuring mechanical and electrical compatibility within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 929665-02-06-I directly replace the MTSW-106-08-G-D-240 in all applications?

A: Direct replacement is possible only when the application operates within the 929665-02-06-I temperature range (-40°C to 105°C) and current requirements do not exceed 2.5A. The MTSW-106-08-G-D-240 supports extended temperature operation to -55°C and 125°C with 3A current capacity. Verify application thermal and electrical specifications before substitution.

Q: What are the mechanical compatibility considerations?

A: Both connectors share 0.100" (2.54mm) mating pitch and row spacing, ensuring PCB footprint compatibility. Minor differences exist in contact length: the 929665-02-06-I has a longer post length (0.210" vs 0.190"), which may affect solder joint geometry on different PCB thicknesses. Overall contact lengths differ by 0.015" (0.38mm), which is negligible for most applications.

Q: Are both parts RoHS compliant?

A: Yes. The MTSW-106-08-G-D-240 is ROHS3 compliant, and the 929665-02-06-I is RoHS compliant. Both meet regulatory requirements for lead-free electronics manufacturing.

Q: What is the difference in contact material?

A: The MTSW-106-08-G-D-240 uses phosphor bronze contacts, while the 929665-02-06-I uses copper alloy contacts. Both materials are gold-plated at the mating surface with identical finish thickness (10.0µin), ensuring equivalent contact resistance and mating performance.

Q: How do the insulation materials differ?

A: The MTSW-106-08-G-D-240 uses polyester with glass fill, while the 929665-02-06-I uses polybutylene terephthalate (PBT) with polyester and glass fill. Both materials achieve UL94 V-0 flammability rating and are suitable for standard PCB assembly processes.
