Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0452802402 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Insulation height (0.457" / 11.60mm)
• Insulation material (Polyamide, Nylon, Glass Filled)
• Material flammability rating (UL94 V-0)

The substitute part Molex 0452802452 maintains full equivalence across all these parameters, with differences limited to product status, packaging format, contact finish specifications on the post, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452802452 is the direct substitute for the obsolete Molex 0452802402. Both connectors are functionally equivalent across all critical mechanical and electrical parameters that determine mating compatibility and board integration.

The primary distinction between these parts is product lifecycle status: the 0452802402 is obsolete, while the 0452802452 is active and currently in production. The 0452802452 offers improved compliance posture, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain identical UL94 V-0 flammability ratings and are suitable for general purpose, medical, military, and telecommunications applications.

The contact finish on the post differs between the two parts: the original uses Tin-Lead with 100.0µin thickness, while the substitute uses Tin with 10.0µin thickness. These differences reflect modern manufacturing standards and do not affect mating performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0452802402 and 0452802452 mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch, row spacing, shrouding configuration, and mounting type. They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the significance of the contact finish difference between these parts?

A: The contact finish on the post (the soldered end) differs in material composition and thickness. The 0452802402 uses Tin-Lead at 100.0µin, while the 0452802452 uses Tin at 10.0µin. The mating contact finish (Gold) is identical on both parts. Post finish differences do not affect mating performance.

Q: Why is the 0452802402 listed as obsolete?

A: Product obsolescence reflects Molex's lifecycle management. The 0452802452 is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance status reflects manufacturing process standards and material composition but does not affect electrical or mechanical compatibility between the two connectors.

Q: What packaging is available for the substitute part?

A: The 0452802452 is supplied in Tray packaging, suitable for automated assembly and high-volume production environments.

Q: Are both parts suitable for medical and military applications?

A: Yes. Both the 0452802402 and 0452802452 are listed for general purpose, medical, military, and telecommunications applications.
