Engineering Selection Recommendations

The TE Connectivity 5-146278-8 is the direct functional equivalent for the obsolete 104346-6. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters.

Compliance and Certification:

Both parts are RoHS Compliant
Both achieve UL94 V-0 flammability rating
Both operate across the full -65°C to 105°C temperature range
Both carry Moisture Sensitivity Level 1 (unlimited shelf life)

Substitution Basis: The 5-146278-8 differs from the 104346-6 only in termination method (solder versus kinked pin), contact finish composition (tin versus tin-lead), and insulation material (LCP versus thermoplastic). These differences do not affect functional compatibility in board-to-board or cable applications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5-146278-8 directly replace the 104346-6 in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (8), contact geometry, mounting method (through-hole), and electrical ratings (3A, 30VAC). The mechanical and electrical interfaces are fully compatible.

Q: What is the difference between the kinked pin termination of the 104346-6 and the solder termination of the 5-146278-8?

A: Kinked pin termination provides mechanical retention during board assembly, while solder termination relies on solder joint formation. Both methods achieve equivalent electrical and mechanical connection strength. Selection depends on assembly process requirements.

Q: Are the contact finish differences (tin-lead versus tin) significant?

A: Both finishes provide equivalent corrosion resistance and electrical performance at the specified 3A current rating. The tin finish of the 5-146278-8 reflects modern RoHS compliance standards, while the tin-lead finish of the 104346-6 represents legacy specifications.

Q: Does the insulation material change from thermoplastic to LCP affect performance?

A: No. Liquid Crystal Polymer (LCP) provides superior thermal and mechanical properties compared to standard thermoplastic. Both materials achieve UL94 V-0 flammability rating and operate across the identical -65°C to 105°C temperature range.

Q: Is the 5-146278-8 available in the same packaging as the 104346-6?

A: The 5-146278-8 is supplied in bulk packaging, whereas the 104346-6 packaging specification was not provided. Confirm packaging requirements with your procurement process.

Q: What is the inventory status of these parts?

A: The 104346-6 has 1006 pieces in stock (obsolete status). The 5-146278-8 has 1354 pieces in stock (active status), providing superior long-term availability.
