Substitute Part Grouping Explanation

Substitution for the 76345-103-40 is determined by strict equivalence in the following critical parameters:

Connector type: Header with male pin contacts
Pitch and position count: 0.100" (2.54mm) spacing, 40 positions in 2-row configuration
Mounting: Through-hole, right-angle orientation
Fastening mechanism: Push-pull engagement
Contact finish: Gold plating on mating surfaces
Flammability compliance: UL94 V-0 rating

The three substitute parts listed below meet these core electrical and mechanical requirements. Variations in secondary parameters such as contact material composition, insulation material type, and post finish do not affect functional interchangeability within the specified application envelope.

Engineering Selection Recommendations

2-146311-0 (TE Connectivity AMP Connectors): This part is the primary recommended substitute. It maintains active product status and provides full functional equivalence to the 76345-103-40. The part is non-RoHS compliant, matching the compliance profile of the original component. Operating temperature range of -65°C to 105°C and 3A current rating are specified. This option is suitable for direct replacement in existing designs without modification.

2-826664-0 (TE Connectivity AMP Connectors): This substitute offers RoHS compliance, making it the preferred choice for new designs subject to RoHS regulations. It maintains active product status and equivalent mechanical and electrical specifications. The higher current rating of 5A provides additional margin for power delivery applications. Insulation color differs (green versus black), which may affect visual identification in assembly but does not impact electrical function.

7-146311-0 (TE Connectivity AMP Connectors): This part shares identical specifications with 2-146311-0 but carries obsolete product status. It is RoHS compliant and suitable for legacy system maintenance where existing inventory exists. This option should not be selected for new production due to its discontinued status.

Frequently Asked Questions (FAQ)

Q: Can the 76345-103-40 be directly replaced with 2-146311-0 or 2-826664-0?

A: Yes. Both parts maintain the critical parameters required for functional equivalence: 40-position, 2-row configuration at 2.54mm pitch, through-hole right-angle mounting, male pin contacts, and push-pull fastening. Mechanical and electrical interchangeability is confirmed.

Q: What is the difference between 2-146311-0 and 2-826664-0?

A: The primary differences are RoHS compliance status and insulation color. 2-826664-0 is RoHS compliant with green insulation, while 2-146311-0 is non-compliant with black insulation. Both are functionally equivalent. Select 2-826664-0 for new designs requiring RoHS compliance; select 2-146311-0 for legacy system compatibility.

Q: Why is 7-146311-0 listed if it is obsolete?

A: 7-146311-0 is included for reference in legacy system documentation and maintenance scenarios. It shares identical specifications with 2-146311-0 but carries discontinued status. For new production, use 2-146311-0 or 2-826664-0 instead.

Q: Are there differences in contact finish thickness between substitutes?

A: Yes. The main part and 2-146311-0 and 7-146311-0 specify 30.0µin (0.76µm) gold plating on mating contacts. Part 2-826664-0 specifies 3.90µin (0.099µm), which is thinner. This difference does not affect functional interchangeability within standard application environments.

Q: What is the significance of the breakaway feature in substitute parts?

A: The breakaway feature in TE Connectivity AMPMODU Mod II connectors allows individual positions to be separated if required. This feature does not affect compatibility with the original 76345-103-40 and provides additional design flexibility in the substitute parts.

Q: Which substitute should be selected for new product designs?

A: For new designs, 2-826664-0 is recommended due to its active product status and RoHS compliance. For legacy system maintenance or where non-RoHS compliance is acceptable, 2-146311-0 is the appropriate choice.
