Key Parameters

Substitute Part Grouping Explanation

The Molex 0452801452 qualifies as a direct substitute for the 0452801402 based on matching electrical and mechanical parameters. Both connectors share identical specifications across all critical substitution criteria: connector type (header), contact type (male pin), position count (14), row configuration (2 rows), mating pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), mounting method (through hole), shrouding style (shrouded 4-wall), fastening mechanism (push-pull), insulation height (0.457"/11.60mm), contact shape (square), insulation material (polyamide/nylon glass-filled), and flammability rating (UL94 V-0).

The primary distinction between these parts lies in product status and compliance posture. The 0452801402 is obsolete, while the 0452801452 maintains active production status with ROHS3 compliance. Both parts belong to the same Micro-Fit 3.0 BMI CPI 45280 series and are functionally interchangeable in applications requiring this connector footprint and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452801452 is the appropriate selection for applications currently using or requiring the 0452801402. Both connectors maintain identical mechanical and electrical interfaces, ensuring direct compatibility in existing PCB designs and cable assemblies.

The 0452801452 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 0452801452 achieves ROHS3 compliance, meeting regulatory requirements for products destined for markets with RoHS restrictions. The 0452801402, classified as RoHS non-compliant, presents supply and regulatory constraints for new designs and ongoing production.

The contact finish difference on the post (tin-lead versus tin) reflects manufacturing process evolution. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Are the 0452801402 and 0452801452 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), insulation height (0.457"/11.60mm), shrouding configuration (4-wall), and mounting method (through hole). PCB footprints and mating interfaces are identical.

Q: What is the primary difference between these two parts?

A: The 0452801402 is obsolete with RoHS non-compliant status, while the 0452801452 is an active product with ROHS3 compliance. The contact finish on the post differs (tin-lead versus tin), reflecting current manufacturing standards.

Q: Can I use the 0452801452 as a direct replacement in existing designs?

A: Yes. The 0452801452 functions as a direct substitute without requiring PCB redesign or assembly process modifications. The electrical and mechanical interfaces are fully compatible.

Q: Does the contact finish difference affect electrical performance?

A: No. Both tin-lead and tin finishes provide equivalent electrical conductivity and solder joint reliability in through-hole applications. The difference reflects manufacturing process updates rather than functional capability.

Q: What packaging is available for the 0452801452?

A: The 0452801452 is supplied in tray packaging, suitable for automated assembly processes and bulk handling.

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

A: Yes. Both connectors are specified for general purpose, medical, military, and telecommunications applications. The 0452801452 offers the advantage of active production status and current compliance certifications.
