Key Parameters

Substitute Part Grouping Explanation

The Molex 0872642452 qualifies as a direct substitute for the 0872642450 based on the following critical parameters:

• Identical connector type (Receptacle)
• Identical position count (24 positions)
• Identical mating pitch (0.079" / 2.00mm)
• Identical row configuration (2 rows with 0.079" spacing)
• Identical mounting style (Through Hole, Right Angle)
• Identical mating contact finish (Gold, 15.0µin thickness)
• Identical electrical ratings (1A current, 125VAC voltage)
• Identical operating temperature range (-55°C ~ 105°C)
• Identical contact shape (Square)
• Identical termination method (Solder)
• Identical fastening type (Push-Pull)

The primary distinction between these parts is product status and compliance certification, not functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0872642452 is the direct functional equivalent of the 0872642450. Selection between these parts should be based on the following criteria:

For Legacy System Maintenance: The 0872642450 remains available in inventory (880 units) and maintains identical electrical and mechanical specifications. This part is suitable for repair and maintenance of existing systems where component-level compatibility is the primary requirement.

For New Production and Compliance-Driven Applications: The 0872642452 is the recommended selection. This part carries active product status and ROHS3 compliance certification, whereas the 0872642450 is classified as obsolete and RoHS non-compliant. The 0872642452 ensures alignment with current regulatory requirements and supply chain sustainability.

Post Finish Consideration: The 0872642450 features tin-lead post finish, while the 0872642452 features tin post finish. Both maintain identical post finish thickness (100.0µin / 2.54µm) and electrical performance. The tin post finish of the 0872642452 reflects modern lead-free manufacturing standards.

Both parts share identical mating contact specifications, mechanical dimensions, electrical ratings, and environmental operating ranges, confirming full interchangeability at the functional level.

Frequently Asked Questions (FAQ)

Q: Are the 0872642450 and 0872642452 mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch spacing (0.079" / 2.00mm), mounting configuration (through-hole right-angle), and contact geometry. They are fully mechanically interchangeable in board-level applications.

Q: What is the difference between these two parts?

A: The primary differences are product status and compliance certification. The 0872642450 is obsolete and RoHS non-compliant with tin-lead post finish. The 0872642452 is active, ROHS3 compliant, and features tin post finish. All electrical and mechanical parameters are identical.

Q: Can I use the 0872642452 as a direct replacement for the 0872642450 in existing designs?

A: Yes. The 0872642452 is a direct functional substitute. No design modifications are required. The identical electrical ratings (1A, 125VAC), operating temperature range (-55°C ~ 105°C), and mechanical specifications ensure seamless compatibility.

Q: Why does the 0872642450 show as obsolete?

A: The 0872642450 is classified as obsolete by the manufacturer. The 0872642452 represents the current active equivalent within the Milli-Grid 87264 series and is the recommended selection for new designs and ongoing production.

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

A: The 0872642452 is ROHS3 compliant, meeting current regulatory requirements for restricted hazardous substances. The 0872642450 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 0872642452 is the appropriate selection.

Q: Does packaging differ between these parts?

A: Yes. The 0872642450 packaging is not specified in available documentation. The 0872642452 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications before ordering.

Q: Are the contact finishes compatible?

A: Yes. Both parts feature gold-plated mating contacts (15.0µin thickness) for identical signal integrity and reliability. The post finish differs (tin-lead versus tin), but both maintain equivalent electrical performance and identical thickness specifications.
