Engineering Selection Recommendations

Both the Amphenol ICC 52601-S50-8LF and 3M N2550-6V0C-RB-WG are Active status products with identical mechanical interface specifications and full RoHS compliance. The parts are electrically and mechanically interchangeable for standard PCB assembly applications.

The 3M N2550-6V0C-RB-WG provides a wider operating temperature minimum of -55°C compared to the Amphenol ICC part at -65°C. For applications requiring operation below -55°C, the Amphenol ICC 52601-S50-8LF is the appropriate selection. Both parts meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture bake-out requirements during standard PCB assembly.

The 3M part includes keying slot and pick-and-place features, which may provide manufacturing process advantages in automated assembly environments. Contact finish thickness on the 3M part is thicker on both mating and post surfaces, potentially offering enhanced durability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Are the 52601-S50-8LF and N2550-6V0C-RB-WG mechanically interchangeable?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), 50-position configuration, 2-row layout, shrouded 4-wall design, and push-pull fastening. PCB footprints and mating interface dimensions are compatible.

Q: What is the difference in operating temperature range?

A: The Amphenol ICC 52601-S50-8LF operates from -65°C to 105°C. The 3M N2550-6V0C-RB-WG operates from -55°C to 105°C. For applications requiring operation below -55°C, the Amphenol ICC part is required.

Q: Do both parts require moisture bake-out before assembly?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out is required prior to standard PCB assembly processes.

Q: What packaging formats are available?

A: The Amphenol ICC 52601-S50-8LF is supplied in Tray packaging. The 3M N2550-6V0C-RB-WG is supplied in Cut Tape (CT) packaging. Packaging format selection depends on assembly process requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes. Both the Amphenol ICC 52601-S50-8LF and 3M N2550-6V0C-RB-WG are RoHS Compliant and carry ECCN EAR99 classification.

Q: What is the difference in contact finish thickness?

A: The Amphenol ICC part specifies 15.0µin (0.38µm) mating finish and 100.0µin (2.54µm) post finish. The 3M part specifies 30.0µin (0.76µm) mating finish and 200.0µin (5.08µm) post finish. Thicker finishes on the 3M part may provide extended durability in high-cycle mating applications.
