Engineering Selection Recommendations
All three parts (2FA1-NDSJ-C04-0, FA1-NDSJ-C04-0, and FA1-NDSJ-C04-6) are active production components manufactured by Amphenol RF and maintain full compliance with ROHS3 and REACH regulations. Each part carries EAR99 ECCN classification and identical HTSUS coding (8536.69.4010).
Selection Basis:
The substitute parts FA1-NDSJ-C04-0 and FA1-NDSJ-C04-6 are functionally equivalent to the main part 2FA1-NDSJ-C04-0 across all critical electrical parameters: 50 Ohm impedance, 6 GHz maximum frequency, 0.3 dB insertion loss, and identical operating temperature range (-40°C to 100°C). All three parts support the same cable groups and maintain 100 mating cycles with latch lock fastening.
Material composition differences (Phosphor Bronze vs. Beryllium Copper for center contacts; Zinc Die Cast vs. Brass for body material) do not alter electrical performance within the specified parameter envelope. Both substitute parts include additional components (housing and locking clip) compared to the main part, which represents an enhancement rather than a limitation.
Selection between these three parts should be based on inventory availability, packaging requirements (bulk vs. standard), and component inclusion preferences for assembly operations.
Frequently Asked Questions (FAQ)
Q: Can FA1-NDSJ-C04-0 and FA1-NDSJ-C04-6 be used interchangeably with 2FA1-NDSJ-C04-0 in RF applications?
A: Yes. All three parts meet identical electrical specifications: 50 Ohm impedance, 6 GHz maximum frequency, 0.3 dB insertion loss, and -40°C to 100°C operating temperature. They support the same cable groups (RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907) and employ identical connector style (SMB Fakra), type (Jack, Female Socket), and termination methods (crimp contact and shield).
Q: What are the differences between the main part and substitute parts?
A: The primary differences are material composition and component inclusion. The main part 2FA1-NDSJ-C04-0 uses Phosphor Bronze center contacts and Zinc Die Cast body material, with 3 included components. The substitute parts FA1-NDSJ-C04-0 and FA1-NDSJ-C04-6 use Beryllium Copper center contacts and Brass body material, with 5 included components (adding housing and locking clip). These material variations do not affect electrical performance within the specified parameter range.
Q: Are there packaging differences between these parts?
A: The main part 2FA1-NDSJ-C04-0 packaging is not specified in the documentation. Both substitute parts (FA1-NDSJ-C04-0 and FA1-NDSJ-C04-6) are supplied in bulk packaging. Inventory levels differ: 2FA1-NDSJ-C04-0 has 753 pieces, FA1-NDSJ-C04-0 has 2086 pieces, and FA1-NDSJ-C04-6 has 853 pieces available.
Q: Do all three parts meet the same compliance standards?
A: Yes. All three parts are ROHS3 compliant, REACH affected, carry EAR99 ECCN classification, and share identical HTSUS code (8536.69.4010). All maintain MSL 1 (Unlimited) moisture sensitivity level and are in active production status.
Q: Which substitute part should be selected for new designs?
A: Both FA1-NDSJ-C04-0 and FA1-NDSJ-C04-6 are suitable for new designs. Selection should be based on inventory availability, packaging format preference, and whether the additional components (housing and locking clip) included in the substitute parts provide assembly advantages for your application. The higher inventory level of FA1-NDSJ-C04-0 (2086 pieces) may support larger production volumes.
Q: Are the center contact material differences (Phosphor Bronze vs. Beryllium Copper) significant?
A: Both materials are acceptable for 50 Ohm RF connector applications within the specified parameter envelope. The material difference does not alter the electrical performance specifications provided: impedance, frequency response, insertion loss, or operating temperature range remain identical across all three parts.
