Engineering Selection Recommendations

Direct Equivalent (3-794682-8):

The TE Connectivity AMP Connectors 3-794682-8 is the direct equivalent to the obsolete 794682-8. This part maintains identical electrical and mechanical specifications while offering active product status. The primary distinction is ROHS3 compliance certification, which the original part does not carry. The packaging format differs (Tray versus unspecified), and the contact finish on the post is pure Tin rather than Tin-Lead. This substitute is recommended for applications requiring direct form-fit-function replacement with improved regulatory compliance.

Similar Substitute (0430450827):

The Molex 0430450827 rectangular connector header provides functional equivalence across all critical parameters including connector type, contact configuration, pitch, mounting method, and operating temperature range. This part offers higher voltage rating (600V versus 250V) and specified current rating (8A), providing enhanced electrical performance margins. The insulation material differs (Liquid Crystal Polymer with glass fill versus Polyamide), and the insulation height is slightly increased (0.390" versus 0.364"). Both substitute parts carry ROHS3 compliance and unlimited moisture sensitivity rating. The Molex alternative is suitable for applications where cross-manufacturer compatibility is acceptable and enhanced electrical specifications are beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 3-794682-8 be used as a direct replacement for the obsolete 794682-8?

A: Yes. The 3-794682-8 maintains identical electrical and mechanical specifications including connector type, position count, pitch, mounting configuration, and operating temperature range. The part is electrically and mechanically interchangeable. The primary differences are product status (Active versus Obsolete), RoHS compliance certification (ROHS3 Compliant versus Not applicable), and contact finish on the post (Tin versus Tin-Lead).

Q: What are the key differences between the TE Connectivity and Molex substitutes?

A: Both substitutes maintain the critical parameters of 8-position, 2-row configuration with 0.118" pitch and through-hole solder termination. The Molex 0430450827 offers higher voltage rating (600V versus 250V), specified current rating (8A), and different insulation material (Liquid Crystal Polymer with glass fill versus Polyamide). The insulation height is slightly increased on the Molex part (0.390" versus 0.364"). Both are ROHS3 compliant and suitable for the same operating temperature range.

Q: Are there mechanical compatibility concerns when substituting the Molex part?

A: The Molex 0430450827 has a slightly increased insulation height (0.390" versus 0.364" on the original). This 0.026" difference may affect board layout clearances in space-constrained applications. All other mechanical parameters including pitch, row spacing, contact post length, and mounting configuration are identical. Physical verification in the target application is necessary to confirm clearance compatibility.

Q: What packaging formats are available for these substitutes?

A: The 3-794682-8 direct equivalent is supplied in Tray packaging. The Molex 0430450827 is also supplied in Tray packaging. The original 794682-8 packaging format is not specified in the available documentation.

Q: Do these substitutes maintain the same contact finish specifications?

A: The main part features Gold mating contact finish (30.0µin thickness) with Tin-Lead post finish (100.0µin thickness). The 3-794682-8 maintains Gold mating finish but uses pure Tin for the post finish. The Molex 0430450827 uses Tin for both mating and post contact finishes. These variations do not affect electrical performance for general purpose applications within the specified voltage and current parameters.

Q: Are all three parts suitable for automotive applications?

A: The original 794682-8 and 3-794682-8 are specified for general purpose applications. The Molex 0430450827 is explicitly rated for automotive, general purpose, industrial, medical, and telecommunications applications. For automotive use, the Molex substitute provides documented suitability across automotive specifications.

Q: What is the significance of the RoHS compliance difference?

A: The original 794682-8 carries "Not applicable" RoHS status, indicating it predates or falls outside RoHS regulatory scope. Both substitutes are ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations. For new designs or applications subject to RoHS requirements, either substitute is appropriate.
