Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0455580002 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating interface (Header, Male Pin)
• Position count and row configuration (6 positions, 2 rows)
• Pitch specifications (0.165" / 4.20mm mating pitch and row spacing)
• Mounting style and orientation (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Electrical ratings (8A current, 600V voltage)
• Operating temperature range (-40°C ~ 105°C)
• Termination method (Solder)
• Material and finish specifications (Brass contacts, Tin finish)

The substitute part 0455580003 maintains identical electrical, mechanical, and dimensional characteristics across all these parameters, with the primary distinction being product status (Active vs. Obsolete) and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0455580003 is the direct active equivalent for the obsolete 0455580002. Both parts are functionally and mechanically identical across all specified electrical and dimensional parameters. The 0455580003 is the recommended selection for new designs and ongoing production due to its active product status and confirmed compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute part maintains full compatibility with existing mating connectors and PCB layouts designed for the original 0455580002.

Frequently Asked Questions (FAQ)

Q: Can the 0455580003 be used as a direct replacement for the 0455580002 in existing assemblies?

A: Yes. The 0455580003 is mechanically and electrically identical to the 0455580002 across all specified parameters, including pitch, position count, row configuration, mounting style, electrical ratings, and contact materials. Direct substitution is supported without design modifications.

Q: What is the primary difference between these two part numbers?

A: The 0455580002 is classified as obsolete, while the 0455580003 is an active product. The 0455580003 also includes documented RoHS3 compliance and REACH unaffected status. Functionally, both parts are equivalent.

Q: Are there packaging differences between the two parts?

A: The 0455580002 is supplied in standard packaging, while the 0455580003 is supplied in bulk packaging. This distinction does not affect the connector's electrical or mechanical performance.

Q: What mating connectors are compatible with these headers?

A: Both the 0455580002 and 0455580003 are compatible with Molex Mini-Fit Jr 45558 series receptacle connectors featuring matching 0.165" (4.20mm) pitch and 6-position, 2-row configuration.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts are rated for operating temperatures from -40°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the current-carrying capacity of these connectors?

A: Both the 0455580002 and 0455580003 are rated for 8A per contact at 600V maximum voltage.
