Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0875684491 is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 44 positions
• Pitch & Row Configuration: 0.079" (2.00mm) pitch with 2-row layout and matching row spacing
• Cable Termination Method: IDC termination for 28 AWG ribbon cable
• Contact Material & Finish: Gold-plated female socket contacts
• Fastening & Mounting: Locking ramp fastening with free hanging in-line mounting
• Series Compatibility: Milli-Grid 87568 series

The substitute part 0875684493 maintains identical electrical and mechanical specifications across all these parameters, differing only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0875684493 is the direct functional equivalent for the obsolete 0875684491. Both parts are identical in electrical and mechanical specifications, ensuring seamless integration into existing designs without modification.

The primary distinction is product status and regulatory compliance. The 0875684493 is currently in active production and carries ROHS3 compliance certification, whereas the 0875684491 is obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance documentation, the 0875684493 is the appropriate selection.

Packaging differs between the two parts: the 0875684491 is supplied without specified packaging, while the 0875684493 is supplied in trays. This packaging difference does not affect connector functionality or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0875684493 directly replace the 0875684491 in existing assemblies?

A: Yes. Both connectors are electrically and mechanically identical. The 0875684493 maintains the same 44-position configuration, 0.079" pitch, IDC termination for 28 AWG ribbon cable, gold contact finish, and locking ramp fastening. No design modifications are required.

Q: What is the significance of the product status difference?

A: The 0875684491 is obsolete and no longer manufactured. The 0875684493 is in active production, ensuring long-term availability for procurement and support. For systems requiring component traceability and ongoing supply, the active part is the appropriate choice.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and manufacturing standard, not a functional specification. Both connectors perform identically in circuit applications. However, systems subject to RoHS requirements should specify the 0875684493 for regulatory documentation purposes.

Q: Are there packaging considerations when switching between these parts?

A: The 0875684493 is supplied in trays, while the 0875684491 has no specified packaging. This affects handling and storage logistics but does not impact connector performance or electrical characteristics.

Q: What parameters must remain constant for substitution within the Milli-Grid 87568 series?

A: Position count (44), pitch (0.079"), row configuration (2 rows), cable termination method (IDC), wire gauge (28 AWG), contact finish (gold), and fastening type (locking ramp) must all remain unchanged for direct substitution.
