Engineering Selection Recommendations

Molex 0901220140 and 0901220780 (C-Grid III 90122 Series)

Both Molex variants are active products with ROHS3 compliance and REACH unaffected status. These parts satisfy all critical dimensional and functional parameters. The 0901220140 features tin mating contact finish, while 0901220780 provides gold mating contact finish matching the original part specification. Both are available in high inventory quantities (750 and 1154 units respectively). The Molex series is suitable for automotive and general-purpose applications.

3M 2340-5121-TG (2300 Series)

This 3M connector maintains dimensional compatibility with contact lengths and insulation height closely aligned to the original part. It provides 3A current rating matching the main part specification and operates across -55°C to 105°C. The part is active and features gold mating contact finish with copper alloy construction. RoHS non-compliance and REACH affected status align with the original part's regulatory position.

3M 929667-04-20-I (929 Series)

This 3M header offers active product status with full RoHS compliance and REACH unaffected designation. It features gold plating on both mating and post contacts with copper alloy construction. Operating temperature range of -40°C to 105°C and 2.5A current rating remain within acceptable parameters. The part is suitable for board-to-board applications and provides the highest regulatory compliance profile among available substitutes.

Regulatory Compliance Considerations

For applications requiring RoHS3 compliance and REACH unaffected status, Molex 0901220140, Molex 0901220780, and 3M 929667-04-20-I are preferred selections. For applications where regulatory status matches the original obsolete part, 3M 2340-5121-TG provides dimensional and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the TE Connectivity 1-104354-7?

A: Substitution requires matching of critical parameters: 40-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing, through-hole right-angle mounting, male pin contacts, square contact shape, unshrouded design, push-pull fastening, and UL94 V-0 flammability rating. Operating temperature range, current rating, and contact material must remain within acceptable operational limits.

Q: Are the Molex C-Grid III parts fully compatible with the original TE Connectivity connector?

A: Yes. Molex 0901220140 and 0901220780 match all critical dimensional and functional parameters. Both feature identical position count, pitch spacing, mounting orientation, and fastening mechanism. The primary difference is contact finish: 0901220140 provides tin mating finish, while 0901220780 provides gold mating finish. Both are solder-termination compatible.

Q: What is the difference between Molex 0901220140 and 0901220780?

A: Both parts are identical except for mating contact finish. The 0901220140 features tin mating contact finish, while 0901220780 features gold mating contact finish. Selection depends on application requirements for contact material compatibility and corrosion resistance. Both are packaged differently (tray versus bulk) and maintain identical electrical and mechanical specifications.

Q: Can I use the 3M 929667-04-20-I as a direct replacement?

A: The 3M 929667-04-20-I is functionally compatible for board-to-board applications. It matches all critical parameters including position count, pitch, mounting type, and fastening mechanism. The primary distinction is operating temperature range (-40°C to 105°C versus -65°C to 105°C) and current rating (2.5A versus 3A). Applications operating within -40°C to 105°C and requiring less than 2.5A current can use this part directly.

Q: What are the packaging differences among the substitute parts?

A: Molex 0901220140 is supplied in tray packaging, Molex 0901220780 in bulk packaging, and 3M 2340-5121-TG packaging is not specified. Packaging selection affects handling, storage, and integration into assembly processes but does not impact electrical or mechanical compatibility.

Q: Which substitute part offers the best regulatory compliance?

A: The 3M 929667-04-20-I provides the highest regulatory compliance profile with full RoHS compliance and REACH unaffected status. Both Molex variants (0901220140 and 0901220780) are ROHS3 compliant and REACH unaffected. The 3M 2340-5121-TG maintains RoHS non-compliant and REACH affected status, matching the original part's regulatory position.

Q: Are there differences in contact material between the substitute parts?

A: Yes. The TE Connectivity original and 3M parts use copper alloy contacts, while both Molex variants use brass contacts. Both materials are acceptable for general-purpose and automotive applications. Contact finish specifications vary: the original part features gold mating finish with tin-lead post finish, while substitutes offer combinations of gold, tin, or gold post finishes depending on the specific part number.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are currently in stock: Molex 0901220140 (750 units), Molex 0901220780 (1154 units), 3M 2340-5121-TG (873 units), and 3M 929667-04-20-I (778 units). The original TE Connectivity part has 1018 units available but is classified as obsolete.
