Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0875684091 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 40 positions at 0.079" (2.00mm) pitch in a 2-row configuration
• Cable Termination Method: IDC termination for 28 AWG ribbon cable
• Contact Material & Finish: Gold plating at 15.0µin (0.38µm) thickness
• Mechanical Interface: Free hanging in-line mounting with locking ramp fastening and polarizing key
• Series Compatibility: Milli-Grid 87568 series

The substitute part 0875684093 maintains identical electrical and mechanical specifications across all these parameters, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0875684093 is the direct functional equivalent to the 0875684091. Both connectors are electrically and mechanically identical across all contact, pitch, termination, and mounting specifications.

The primary distinction is product lifecycle status: the 0875684091 is obsolete, while the 0875684093 is active production. Additionally, the 0875684093 achieves ROHS3 compliance, whereas the 0875684091 is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 0875684093 is the appropriate selection. Both parts maintain identical moisture sensitivity classification and export control designations.

Frequently Asked Questions (FAQ)

Q: Are the 0875684091 and 0875684093 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (40), row configuration (2 rows), mounting type (free hanging in-line), and fastening mechanism (locking ramp). They are direct mechanical equivalents.

Q: Can the 0875684093 replace the 0875684091 in existing assemblies?

A: Yes. The 0875684093 maintains identical electrical and mechanical specifications, including contact type, finish, termination method, and cable gauge compatibility. No design modifications are required.

Q: What is the difference in packaging between these parts?

A: The 0875684091 packaging format is not specified in the available data. The 0875684093 is supplied in tray packaging. Confirm packaging requirements for your procurement process.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a material composition and manufacturing standard, not a functional or mechanical parameter. Both connectors perform identically in circuit applications. The 0875684093 meets current environmental regulations, making it preferable for new production.

Q: Are both parts suitable for 28 AWG ribbon cable termination?

A: Yes. Both connectors are specified for IDC termination with 28 AWG ribbon cable and feature identical contact geometry and termination force characteristics.
