Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the TE Connectivity 1-104355-7?

A: Substitution requires matching of critical parameters: 40-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, through-hole right-angle mounting, solder termination, push-pull fastening, square contact shape, and UL94 V-0 flammability rating. All listed substitutes meet these requirements.

Q: How do contact finish differences affect substitution?

A: The original part features tin-lead contact finish. Substitute parts offer tin or gold finishes. Gold finishes provide enhanced corrosion resistance and are suitable for applications requiring extended shelf life or exposure to corrosive environments. Tin finishes are standard for general-purpose applications. Selection depends on specific environmental and reliability requirements.

Q: Are there differences in contact length between the original and substitute parts?

A: Yes. The original part specifies 0.230" (5.84mm) mating contact length and 0.120" (3.05mm) post length. Substitute parts vary: Molex parts feature 0.266" (6.75mm) mating length; 3M 2340-5121-TG matches the original at 0.230" (5.84mm); 3M 929667-04-20-I specifies 0.235" (5.97mm). These variations may affect mating depth and board layout considerations.

Q: What is the significance of RoHS and REACH compliance status?

A: The original TE Connectivity part is RoHS non-compliant and REACH affected. Molex substitutes (0901220140 and 0901220780) are ROHS3 compliant and REACH unaffected, providing regulatory advantages for new designs and markets with environmental restrictions. The 3M 929667-04-20-I is RoHS compliant and REACH unaffected. The 3M 2340-5121-TG maintains the original non-compliant status.

Q: How do operating temperature ranges compare?

A: The original part operates from -65°C to 105°C. The 3M 2340-5121-TG operates from -55°C to 105°C, and the 3M 929667-04-20-I from -40°C to 105°C. Both represent narrower ranges. Molex parts do not specify operating temperature. Selection depends on application temperature requirements.

Q: What packaging options are available for substitutes?

A: The Molex 0901220140 is supplied in tray packaging. The Molex 0901220780 is supplied in bulk packaging. The 3M 2340-5121-TG packaging is not specified. The 3M 929667-04-20-I is supplied in bulk packaging. Packaging selection affects handling, storage, and integration into assembly processes.

Q: Are current and voltage ratings consistent across all substitutes?

A: The original part is rated at 3A and 30VAC. The 3M 2340-5121-TG matches at 3A with unspecified voltage rating. The 3M 929667-04-20-I is rated at 2.5A with unspecified voltage. Molex parts do not specify current or voltage ratings. Applications requiring the full 3A rating should prioritize the 3M 2340-5121-TG or verify Molex part suitability through manufacturer documentation.

Q: What is the inventory status of substitute parts?

A: Molex 0901220140: 750 units in stock. Molex 0901220780: 1154 units in stock. 3M 2340-5121-TG: 873 units in stock. 3M 929667-04-20-I: 778 units in stock. All substitutes are currently available, addressing the obsolescence of the original TE Connectivity part.
