Key Parameters

Substitute Part Grouping Explanation

The Molex 0875682091 has one direct substitute: 0875682093. This substitution is valid based on identical electrical and mechanical parameters across all critical specifications. Both parts share the same connector type (receptacle), position count (20), pitch (0.079"), row configuration (2 rows at 0.079" spacing), IDC termination method, 28 AWG wire gauge compatibility, gold contact finish with 15.0µin thickness, mounting style (free hanging in-line), fastening mechanism (locking ramp), and feature set (feed through with polarizing key).

The key parameters determining substitution eligibility are:

• Connector type and contact configuration
• Position count and pitch geometry
• Cable termination method and wire gauge
• Contact material and finish specifications
• Mounting and fastening characteristics

Parameter Comparison

Engineering Selection Recommendations

The Molex 0875682093 is the direct substitute for the obsolete 0875682091. Both parts are functionally and mechanically identical across all electrical and physical specifications. The primary distinction is product status and regulatory compliance: the 0875682091 is obsolete and RoHS non-compliant, while the 0875682093 is an active product with ROHS3 compliance. For new designs or system replacements, the 0875682093 is the appropriate selection. Both parts maintain identical moisture sensitivity levels and REACH status, ensuring equivalent performance in environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 0875682093 directly replace the 0875682091 in existing assemblies?

A: Yes. The 0875682093 is mechanically and electrically identical to the 0875682091 across all critical parameters including connector geometry, contact configuration, termination method, and contact finish specifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 0875682091 is obsolete and RoHS non-compliant, while the 0875682093 is an active product with ROHS3 compliance. All functional and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Yes. The 0875682091 packaging is not specified, while the 0875682093 is supplied in Tray packaging. This does not affect connector functionality or compatibility.

Q: What cable specifications are compatible with these connectors?

A: Both connectors accept 28 AWG ribbon cable with IDC termination. The connector features feed-through design and polarizing key for proper cable orientation.

Q: Are these connectors suitable for new product designs?

A: The 0875682093 is suitable for new designs as an active product with current regulatory compliance. The 0875682091 should not be used in new designs due to obsolescence and RoHS non-compliance status.
