Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The FA2-NASP-C04-0 and its identified substitute FA1-NASP-C04-1 share identical specifications in the following critical categories:

Electrical Parameters: Impedance (50 Ohms), frequency rating (4 GHz maximum), insertion loss (0.3 dB), and contact materials (brass with gold plating) are identical across both parts.

Mechanical Parameters: Connector style (SMB, Fakra), connector type (Plug, Male Pin), termination method (crimp for both contact and shield), mounting configuration (panel mount with flange), and fastening type (locking ramp) are equivalent.

Environmental & Compliance Parameters: Operating temperature range (-40°C to 100°C), mating cycle rating (100 cycles), RoHS3 compliance, REACH affected status, and MSL rating (1) are identical.

Cable Compatibility: Both parts support the same cable groups: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907.

The primary difference between these parts is packaging configuration: FA2-NASP-C04-0 includes 2 connectors per package, while FA1-NASP-C04-1 is supplied as a single connector unit in bulk packaging. This distinction affects only procurement quantity and packaging density, not functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both FA2-NASP-C04-0 and FA1-NASP-C04-1 are active production parts from Amphenol RF with identical electrical and mechanical specifications. Selection between these parts is based on packaging requirements and procurement strategy rather than functional performance.

FA2-NASP-C04-0 is appropriate for applications requiring dual-connector packages with integrated housing and ferrule components. This configuration reduces assembly steps when two connectors are needed per unit.

FA1-NASP-C04-1 is appropriate for applications requiring individual connector units or when bulk packaging is preferred for inventory management. The single-connector configuration provides flexibility for mixed-component assemblies.

Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for industrial and commercial RF applications. The identical insertion loss (0.3 dB), impedance (50 Ohms), and frequency rating (4 GHz) confirm electrical interchangeability in circuit designs. Operating temperature range (-40°C to 100°C) and mating cycle rating (100 cycles) are equivalent, supporting identical reliability expectations.

Frequently Asked Questions (FAQ)

Q: Can FA1-NASP-C04-1 be used as a direct replacement for FA2-NASP-C04-0 in circuit applications?

A: Yes. Both parts are electrically and mechanically equivalent. The FA1-NASP-C04-1 provides identical performance in 50 Ohm RF circuits up to 4 GHz. The difference is packaging configuration: FA1-NASP-C04-1 is supplied as a single connector unit, while FA2-NASP-C04-0 includes two connectors per package.

Q: What is the primary difference between these two part numbers?

A: The primary difference is packaging density and included components. FA2-NASP-C04-0 contains 2 connectors, 2 contacts, 2 ferrules, and 1 housing (7 pieces total). FA1-NASP-C04-1 contains 1 connector, 1 contact, and 1 ferrule (3 pieces total) in bulk packaging. All electrical and mechanical specifications are identical.

Q: Are both parts compatible with the same cable types?

A: Yes. Both FA2-NASP-C04-0 and FA1-NASP-C04-1 support identical cable groups: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. Crimp termination specifications are identical for both contact and shield.

Q: Do these parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH affected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010). MSL rating is 1 (Unlimited) for both parts.

Q: What is the maximum frequency rating for both parts?

A: Both FA2-NASP-C04-0 and FA1-NASP-C04-1 are rated for frequencies up to 4 GHz with insertion loss of 0.3 dB.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the identical temperature range of -40°C to 100°C with 100 mating cycles rated for each.

Q: Which part should I select for high-volume production?

A: Selection depends on assembly requirements. FA1-NASP-C04-1 bulk packaging is suitable for high-volume applications where individual connector units are preferred. FA2-NASP-C04-0 dual-connector packaging reduces handling steps when two connectors are required per assembly.

Q: Are the contact materials and plating specifications identical?

A: Yes. Both parts use brass center contacts with gold plating, brass body material with nickel finish, and PTFE dielectric material. These specifications are identical across both part numbers.
