Parameter Comparison

Engineering Selection Recommendations

Both the 2FA1-NZSJ-C04-0 and FA1-NZSJ-C04-0 are active production parts manufactured by Amphenol RF with full ROHS3 compliance and REACH affected status. Selection between these parts is based on the following criteria:

2FA1-NZSJ-C04-0 Selection Criteria:

• Tape and Reel packaging requirement for automated assembly processes
• Phosphor Bronze center contact material specification
• Zinc Die Cast body material requirement
• Lower inventory availability acceptable

FA1-NZSJ-C04-0 Selection Criteria:

• Bulk packaging requirement for manual assembly or kit applications
• Beryllium Copper center contact material specification
• Brass body material requirement
• Higher inventory availability needed for volume production
• Additional included components (Housing and Locking Clip) provide assembly convenience

Both parts maintain identical electrical performance with 0.3 dB insertion loss, 6 GHz maximum frequency, and 50-ohm impedance. Material composition differences between Phosphor Bronze and Beryllium Copper center contacts, as well as Zinc Die Cast versus Brass body materials, do not affect electrical equivalence but may influence mechanical durability and environmental resistance characteristics specific to application requirements.

Frequently Asked Questions (FAQ)

Q: Are the 2FA1-NZSJ-C04-0 and FA1-NZSJ-C04-0 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 50-ohm impedance, 6 GHz maximum frequency, 0.3 dB insertion loss, and PTFE dielectric material. They are electrically equivalent for all RF applications within the specified frequency and impedance range.

Q: What is the difference between Phosphor Bronze and Beryllium Copper center contacts?

A: The center contact material differs between the two parts. The 2FA1-NZSJ-C04-0 uses Phosphor Bronze, while the FA1-NZSJ-C04-0 uses Beryllium Copper. Both materials are gold-plated and provide equivalent electrical performance. Material selection may be driven by specific mechanical durability or environmental resistance requirements.

Q: What is the difference between Zinc Die Cast and Brass body materials?

A: The 2FA1-NZSJ-C04-0 features a Zinc Die Cast body, while the FA1-NZSJ-C04-0 uses Brass. Both are nickel-finished and provide equivalent RF shielding and mechanical performance. Material selection may depend on specific environmental or mechanical stress requirements.

Q: What packaging formats are available?

A: The 2FA1-NZSJ-C04-0 is supplied in Tape and Reel packaging, suitable for automated pick-and-place assembly. The FA1-NZSJ-C04-0 is supplied in Bulk packaging, suitable for manual assembly or kit applications.

Q: What components are included with each part?

A: The 2FA1-NZSJ-C04-0 includes 3 pieces: 1 Connector, 1 Contact, and 1 Ferrule. The FA1-NZSJ-C04-0 includes 5 pieces: 1 Connector, 1 Contact, 1 Ferrule, 1 Housing, and 1 Locking Clip. The additional components in the FA1-NZSJ-C04-0 may provide assembly convenience.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 2FA1-NZSJ-C04-0 and FA1-NZSJ-C04-0 are ROHS3 compliant and REACH affected. Both parts meet current environmental and regulatory requirements.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -40°C to 100°C, supporting applications in industrial, automotive, and telecommunications environments.

Q: What cable types are compatible with these connectors?

A: Both connectors support the same cable group: RG-58, RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, and 9907.

Q: How many mating cycles are rated for these connectors?

A: Both parts are rated for 100 mating cycles, indicating the expected number of connect/disconnect operations before performance degradation.
