Engineering Selection Recommendations

Both the Molex 0702800719 and TE Connectivity 6-146253-1 are active products with ROHS3 compliance and UL94 V-0 flammability ratings. The TE Connectivity part is designated as a manufacturer-recommended substitute and maintains full compatibility across all critical connector parameters including pitch, position count, row configuration, mounting type, and termination method.

The primary differences between these parts are contact finish specifications and post length dimensions. The TE Connectivity part features gold plating on mating contacts with a thinner finish thickness, while the Molex part uses tin plating with greater thickness. The TE Connectivity part also specifies a shorter post length and provides documented operating temperature and current rating parameters.

Selection between these parts should be based on specific application requirements regarding contact finish preference, post length accommodation within the PCB design, and any thermal or current specifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (22), row configuration (2 rows), mounting type (through hole), and fastening mechanism (push-pull). Mating interface dimensions are equivalent within tolerance.

Q: What is the difference in contact finish between these parts?

A: The Molex 0702800719 uses tin plating at 150.0µin thickness on mating contacts. The TE Connectivity 6-146253-1 uses gold plating at 30.0µin thickness. Contact finish selection affects corrosion resistance and electrical performance characteristics in specific environmental conditions.

Q: Do these connectors have different post lengths?

A: Yes. The Molex part has a post length of 0.185" (4.70mm), while the TE Connectivity part has a post length of 0.125" (3.18mm). This difference must be verified against PCB design specifications to ensure proper solder joint formation and mechanical support.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0702800719 and TE Connectivity 6-146253-1 are ROHS3 compliant and carry UL94 V-0 flammability ratings.

Q: What packaging formats are available?

A: The Molex 0702800719 is supplied in bulk packaging. The TE Connectivity 6-146253-1 is supplied in tray packaging. Packaging format may affect handling, storage, and assembly line integration requirements.

Q: Can I use the TE Connectivity part as a direct replacement in existing designs?

A: The TE Connectivity 6-146253-1 is mechanically and electrically compatible for mating interface applications. However, the shorter post length must be evaluated against PCB design specifications to confirm adequate solder joint geometry and mechanical retention.
