Engineering Selection Recommendations

Both the Molex 0873813009 and Amphenol ICC 55510-130LF are active production parts with full RoHS compliance and UL94 V-0 flammability ratings. The Amphenol ICC substitute offers enhanced electrical performance with a 200V voltage rating versus 125V on the Molex part, and a 2A current rating compared to 1.9A. The Amphenol ICC part also extends the operating temperature range to 125°C, providing broader thermal margin. The gold contact finish thickness on the Amphenol ICC part is doubled (30.0µin versus 15.0µin), which may provide extended contact life in high-cycle applications. Both parts share identical pitch spacing, row configuration, and push-pull fastening, ensuring mechanical interchangeability in board-to-board applications. Selection between these parts should be based on specific application requirements for voltage, current, and temperature performance, as well as supply chain availability and cost considerations.

Frequently Asked Questions (FAQ)

Q: What makes the Amphenol ICC 55510-130LF a valid substitute for the Molex 0873813009?

A: Both connectors share identical critical parameters: 30-position receptacle configuration, 0.079" (2.00mm) pitch spacing, 2-row layout with matching row spacing, surface mount termination, push-pull fastening, and gold-plated mating contacts. These parameters define mechanical and electrical compatibility for board-to-board interconnection.

Q: Are there physical differences between these connectors?

A: Yes. The Amphenol ICC part has a slightly taller insulation height (0.177" versus 0.157") and thicker gold plating on mating contacts (30.0µin versus 15.0µin). These differences do not affect pitch-based compatibility but should be considered in height-constrained PCB layouts.

Q: Can I use the Amphenol ICC part in applications rated for 125V?

A: Yes. The Amphenol ICC 55510-130LF is rated for 200V, which exceeds the 125V requirement of the Molex part. It is suitable for any application within the 125V specification.

Q: What is the temperature operating range difference?

A: The Molex part operates from -55°C to 105°C, while the Amphenol ICC part extends to 125°C. For applications requiring operation above 105°C, the Amphenol ICC part provides additional thermal margin.

Q: Are both parts RoHS compliant?

A: Yes. The Molex 0873813009 is ROHS3 compliant, and the Amphenol ICC 55510-130LF is RoHS compliant. Both meet lead-free soldering requirements.

Q: What is the current rating difference?

A: The Molex part is rated for 1.9A per contact, while the Amphenol ICC part is rated for 2A per contact. The Amphenol ICC part provides slightly higher current capacity.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
