Substitute Part Grouping Explanation

Substitution of the Molex 0877594450 is determined by strict equivalence across the following critical parameters:

• Pitch and Position Count: 0.079" (2.00mm) pitch with 44 total positions in 2-row configuration
• Connector Classification: Header type with male pin contacts
• Mounting and Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening system
• Electrical and Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating

The substitute part Amphenol ICC (FCI) 57202-G52-22LF meets all critical substitution criteria. Both connectors share identical pitch spacing, position count, row configuration, mounting type, and termination method. Both are rated UL94 V-0 and comply with RoHS and REACH requirements. The substitute maintains board-to-board connectivity with push-pull fastening and operates within the same environmental and compliance framework.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 57202-G52-22LF is a direct functional equivalent to the Molex 0877594450 for board-to-board connector applications. Both parts are active products with current manufacturing status and full compliance with RoHS and REACH regulations. Both achieve UL94 V-0 flammability certification and maintain MSL 1 moisture sensitivity rating.

The substitute part demonstrates equivalent or superior specifications across all critical parameters. Contact mating length differs by 0.006" (0.19mm), with the substitute providing slightly longer contact engagement. Contact finish thickness on the mating surface is doubled in the substitute part, providing enhanced durability. The substitute part explicitly specifies electrical ratings of 2A (AC/DC) at 200V (AC/DC), whereas the original part does not provide these specifications in the available data.

Packaging differs between the two parts: the original is supplied in tube packaging while the substitute is supplied in bulk packaging. Both parts are currently in stock with adequate inventory levels. Selection between these parts should be based on application-specific requirements regarding contact engagement length, packaging format, and sourcing availability.

Frequently Asked Questions (FAQ)

Q: What makes the Amphenol ICC 57202-G52-22LF a suitable substitute for the Molex 0877594450?

A: Both connectors share identical pitch spacing (0.079" / 2.00mm), position count (44), row configuration (2 rows), mounting type (surface mount), termination method (solder), and fastening mechanism (push-pull). Both are unshrouded headers with square male pin contacts, thermoplastic insulation, and equivalent compliance certifications (UL94 V-0, RoHS, REACH).

Q: Are there any physical differences between these connectors?

A: The contact mating length differs by 0.006" (0.19mm), with the Amphenol part providing 0.157" (4.00mm) versus the Molex part at 0.150" (3.81mm). The Amphenol part also features thicker gold plating on mating contacts (30.0µin versus 15.0µin). These differences do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference in packaging between these parts?

A: The Molex 0877594450 is supplied in tube packaging, while the Amphenol ICC 57202-G52-22LF is supplied in bulk packaging. Tube packaging is typically used for smaller quantities or automated pick-and-place operations, while bulk packaging is used for higher-volume assembly processes.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated, RoHS compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS code (8536.69.4040). Both maintain MSL 1 (unlimited) moisture sensitivity rating. The Molex part is specifically ROHS3 compliant, while the Amphenol part is RoHS compliant.

Q: What electrical specifications should I consider for this connector?

A: The Amphenol ICC substitute specifies 2A (AC/DC) current rating at 200V (AC/DC). The Molex original part does not provide explicit electrical ratings in the available specifications. For applications requiring specific electrical performance verification, the Amphenol part's published ratings provide documented performance parameters.

Q: Can I use these connectors interchangeably in my design?

A: These connectors are functionally equivalent for board-to-board applications with identical pitch, position count, and mounting characteristics. Physical compatibility depends on your PCB layout and mating connector design. The slight difference in contact mating length (0.006") should be evaluated against your specific application requirements.
