Substitute Part Grouping Explanation

Substitute parts for the Molex 0465573447 are identified based on strict electrical and mechanical parameter matching within the SEARAY 46557 series. The substitution criteria are:

• Identical connector type: High Density Array, Female
• Identical number of positions: 120
• Identical pitch: 0.050" (1.27mm)
• Identical number of rows: 4
• Identical mounting type: Surface Mount
• Identical contact finish: Gold with 30.0µin thickness
• Identical height above board: 0.295" (7.50mm)
• Identical mated stacking heights: 9.5mm through 14.5mm
• Identical board guide feature
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

The substitute parts listed below meet all these criteria and differ only in product status (active versus obsolete) and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 0465573345 and 0465573445 are active products within the SEARAY 46557 series and maintain full compliance with ROHS3 and REACH regulations. The primary distinction between these substitutes is the completeness of parametric documentation.

Part 0465573445 provides complete parametric alignment with the obsolete 0465573447, including specified contact finish thickness, height above board, mated stacking heights, and board guide feature confirmation. This part is the preferred substitute for direct replacement applications.

Part 0465573345 is functionally equivalent but with limited parametric documentation in the provided data. Both parts are supplied in Tape & Reel packaging and maintain identical MSL ratings and compliance certifications. Selection between these active alternatives should be based on procurement availability, packaging requirements, and documentation completeness for your specific application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0465573345 and 0465573445 be used interchangeably with the obsolete 0465573447?

A: Both parts are electrically and mechanically equivalent within the SEARAY 46557 series, sharing identical connector type, position count, pitch, row configuration, mounting type, contact finish, and compliance ratings. The 0465573445 provides complete parametric confirmation. Interchangeability is determined by your specific application requirements and PCB design constraints.

Q: What is the difference between the two substitute parts?

A: Both 0465573345 and 0465573445 are active Molex products in Tape & Reel packaging. The 0465573445 includes complete parametric specifications matching the original part. The 0465573345 has limited parametric detail in available documentation but maintains the same core electrical and mechanical characteristics.

Q: Are these parts RoHS compliant?

A: Yes, all three parts (0465573447, 0465573345, and 0465573445) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available for the substitute parts?

A: The substitute parts 0465573345 and 0465573445 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Does the MSL rating affect component handling?

A: All parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
