• Mating pitch: 0.100" (2.54mm)
• Row spacing: 0.100" (2.54mm)
• Mounting method: Through hole with solder termination
• Fastening mechanism: Push-pull
• Shrouding configuration: Shrouded design
• Flammability compliance: UL94 V-0
• RoHS compliance: Compliant
• MSL rating: 1 (Unlimited)

The substitute part 71918-010LF from Amphenol ICC (FCI) meets all critical electrical and mechanical parameters required for functional equivalence in the N3793-2002RB application space.

Parameter Comparison

Engineering Selection Recommendations

Both the N3793-2002RB and 71918-010LF are active production parts with RoHS compliance and UL94 V-0 flammability certification. The 71918-010LF offers increased shrouding (4-wall versus 3-wall configuration) and enhanced contact finish specifications through the GXT™ gold plating process. Selection between these parts should be based on specific application requirements regarding shrouding robustness and contact durability specifications. Both parts carry MSL 1 rating, indicating no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 71918-010LF directly replace the N3793-2002RB in existing designs?

A: Yes. Both parts share identical mating pitch (0.100"), position count (10 in 2 rows), row spacing (0.100"), mounting method (through hole), termination type (solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is established through these aligned parameters.

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

A: The N3793-2002RB features 3-wall shrouding, while the 71918-010LF provides 4-wall shrouding. This difference affects mechanical protection and insertion guidance but does not impact electrical performance or mating compatibility.

Q: Are there packaging differences between these parts?

A: Yes. The N3793-2002RB is supplied in bulk packaging, while the 71918-010LF is supplied in tube packaging. Packaging selection may affect procurement quantities and handling procedures but does not affect component functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability certification, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both carry MSL 1 rating with unlimited moisture sensitivity constraints.

Q: What contact material differences exist between these parts?

A: The N3793-2002RB uses copper alloy contacts, while the 71918-010LF uses phosphor bronze contacts. Both materials support the specified mating contact finish (gold) and post finish (tin) requirements.
