Parameter Comparison

Engineering Selection Recommendations

The Molex 0873400824 is the direct substitute for the obsolete 0873400822. Both connectors share identical mechanical and electrical specifications across all critical mating and functional parameters. The primary distinction is product lifecycle status: the 0873400824 is an active production part with current availability.

For new designs or component replenishment, the 0873400824 is the appropriate selection. The shift from Tin-Lead to Tin post finish and ROHS3 compliance in the substitute part aligns with current manufacturing standards and regulatory requirements. Both parts maintain identical current and voltage ratings, operating temperature range, and mechanical interface specifications, ensuring functional interchangeability in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the 0873400824 directly replace the 0873400822 in existing assemblies?

A: Yes. The 0873400824 is mechanically and electrically identical to the 0873400822 across all mating and functional parameters. Both connectors feature the same 8-position configuration, 0.079" (2.00mm) pitch, surface mount termination, and push-pull fastening. The primary difference is product status and compliance certification.

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

A: The 0873400822 uses Tin-Lead post finish, while the 0873400824 uses Tin post finish. Both maintain identical contact finish thickness (74.8µin / 1.90µm) and identical gold mating contact specifications. The Tin finish in the 0873400824 reflects compliance with current RoHS3 standards.

Q: Are there packaging considerations when switching from 0873400822 to 0873400824?

A: The 0873400824 is supplied in Tube packaging. Packaging format does not affect connector performance or compatibility; it impacts only handling, storage, and procurement logistics.

Q: Does the RoHS3 compliance of the 0873400824 affect compatibility?

A: No. RoHS3 compliance is a manufacturing and regulatory attribute that does not alter the connector's electrical or mechanical performance. The 0873400824 maintains all functional specifications of the 0873400822.

Q: What is the current availability status of these parts?

A: The 0873400822 is obsolete. The 0873400824 is an active production part and is the recommended selection for ongoing procurement and new applications.
