Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0872643850 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (38)
• Mating pitch (0.079" / 2.00mm)
• Number of rows (2)
• Row spacing (0.079" / 2.00mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact type (Female Socket)
• Electrical ratings (1A, 125VAC)
• Operating temperature range (-55°C ~ 105°C)

The Molex 0872643852 meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0872643852 is the qualified substitute for the obsolete 0872643850. Both connectors are electrically and mechanically equivalent across all critical mating and mounting parameters.

The primary distinction between these parts is regulatory compliance status. The 0872643850 is RoHS non-compliant, while the 0872643852 is ROHS3 compliant. For new designs or systems subject to RoHS requirements, the 0872643852 is the appropriate selection. The 0872643852 is currently in active production with confirmed inventory availability.

The contact finish on the post differs between the two parts: the 0872643850 uses tin-lead plating, while the 0872643852 uses tin plating. Both finishes meet the specified electrical and mechanical requirements for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the 0872643852 be used as a direct replacement for the 0872643850 in existing designs?

A: Yes. The 0872643852 is mechanically and electrically equivalent to the 0872643850 across all critical parameters including connector type, position count, pitch, mounting configuration, and electrical ratings. Both connectors are compatible with the same mating plugs and PCB layouts.

Q: What is the difference in post plating between these two parts?

A: The 0872643850 features tin-lead plating on the posts, while the 0872643852 uses tin plating. Both plating specifications meet the electrical and mechanical requirements for this connector series and provide equivalent performance in solder joint formation and long-term reliability.

Q: Why is the 0872643850 listed as obsolete?

A: The 0872643850 is no longer in active production. The 0872643852 represents the current production equivalent and is the recommended part for procurement.

Q: Are there packaging differences between these parts?

A: The 0872643852 is supplied in tube packaging. The original packaging specification for the 0872643850 was not provided. Packaging differences do not affect connector functionality or compatibility.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and material composition specification that does not affect the electrical or mechanical compatibility between these connectors. The choice between RoHS-compliant and non-compliant versions depends on the regulatory requirements of the end application.
