Molex 0875685091 Equivalent & Substitute Parts

Part Overview

The Molex 0875685091 is a 50-position rectangular receptacle connector from the Milli-Grid 87568 series, designed for IDC (Insulation Displacement Contact) termination with 28 AWG ribbon cable. This connector features gold-plated female socket contacts, a locking ramp fastening mechanism, and polarizing key features for secure mating. The part is currently classified as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0875685091 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (50)
• Pitch and row spacing (0.079" / 2.00mm)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Contact finish specification (Gold, 15.0µin thickness)
• Mounting configuration (Free Hanging, In-Line)
• Fastening mechanism (Locking Ramp)
• Series compatibility (Milli-Grid 87568)

The substitute part Molex 0875685093 meets all these criteria, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0875685093 is the direct functional equivalent of the obsolete 0875685091. Both parts are identical in electrical and mechanical specifications, including connector geometry, contact configuration, and termination method. The primary distinctions are:

• Product status: 0875685093 is active and currently manufactured, while 0875685091 is obsolete
• RoHS compliance: 0875685093 meets ROHS3 requirements, whereas 0875685091 is non-compliant
• Packaging: 0875685093 is supplied in tray format, offering improved handling and inventory management

For new designs or system replacements, the 0875685093 is the appropriate selection. For legacy system maintenance requiring exact original specifications, the 0875685091 remains functionally compatible with existing mated connectors and cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 0875685093 directly replace the 0875685091 in existing assemblies?

A: Yes. Both connectors are mechanically and electrically identical. The 0875685093 will mate with existing 50-position IDC plugs and ribbon cables terminated for 28 AWG wire. No redesign or reconfiguration is required.

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

A: The 0875685091 is RoHS non-compliant, while the 0875685093 meets ROHS3 standards. For applications subject to RoHS regulations or customer requirements, the 0875685093 is the compliant choice. Both parts use identical gold contact finishes and materials otherwise.

Q: Does packaging format affect connector performance?

A: No. The tray packaging of the 0875685093 versus bulk packaging of the 0875685091 is a logistics consideration only. Connector electrical and mechanical performance is identical. Tray packaging provides better protection during storage and handling.

Q: Are these connectors compatible with other Milli-Grid 87568 series components?

A: Yes. Both the 0875685091 and 0875685093 are part of the Milli-Grid 87568 series and are compatible with all other components within this series that share the same pitch, row spacing, and contact configuration.

Q: What wire gauge must be used with these connectors?

A: These connectors are specified for 28 AWG ribbon cable only. The IDC termination mechanism is designed for this gauge. Using wire of different gauges will result in improper contact engagement and potential connection failure.
