Substitute Part Grouping Explanation

Substitution of the Amphenol RF 2FA1-NCSJ-C01-0 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Connector style and type (SMB Fakra jack, female socket)
• Impedance specification (50 ohms)
• Frequency maximum rating (6 GHz)
• Insertion loss (0.3 dB)
• Contact and shield termination method (crimp)

Mechanical Equivalence Requirements:

• Mounting configuration (free hanging, in-line)
• Fastening type (latch lock)
• Operating temperature range (-40°C ~ 100°C)
• Mating cycle rating (100 cycles)
• Cable group compatibility (RG-174, 188, 188A, 316, LMR-100, M17/119-RG174)

Compliance Requirements:

• RoHS3 compliance
• REACH affected status
• Gold center contact plating
• PTFE dielectric material
• Nickel body finish

The substitute part FA1-NCSJ-C01-0 meets all electrical, mechanical, and compliance parameters. Differences in center contact material (beryllium copper versus phosphor bronze), body material (brass versus zinc die cast), and packaging configuration do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the 2FA1-NCSJ-C01-0 and FA1-NCSJ-C01-0 are active products manufactured by Amphenol RF and maintain identical electrical performance specifications for 50-ohm coaxial RF applications. Both parts are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection between these parts should be based on packaging and inventory requirements. The 2FA1-NCSJ-C01-0 is supplied in standard packaging with 790 units currently in stock. The FA1-NCSJ-C01-0 is supplied in bulk packaging with 3004 units currently in stock and includes additional components (housing and locking clip) in its package contents.

For applications requiring immediate availability in smaller quantities, the 2FA1-NCSJ-C01-0 is suitable. For high-volume production or applications benefiting from bulk packaging economics, the FA1-NCSJ-C01-0 provides greater inventory availability and supplementary components.

Both parts maintain identical electrical characteristics, frequency response, temperature operating range, and mating cycle ratings. No performance degradation or functional limitation occurs when substituting between these parts within their specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 2FA1-NCSJ-C01-0 and FA1-NCSJ-C01-0 electrically identical?

A: Yes. Both parts maintain identical electrical specifications including 50-ohm impedance, 6 GHz maximum frequency, 0.3 dB insertion loss, and gold-plated center contacts with PTFE dielectric material. Electrical performance is equivalent across all RF signal transmission applications.

Q: What are the differences between these two part numbers?

A: The primary differences are packaging configuration and included components. The 2FA1-NCSJ-C01-0 uses standard packaging, while the FA1-NCSJ-C01-0 uses bulk packaging and includes additional components (housing and locking clip). Center contact material differs (phosphor bronze versus beryllium copper) and body material differs (zinc die cast versus brass), but these material variations do not affect functional equivalence within specified parameters.

Q: Can I substitute the FA1-NCSJ-C01-0 for the 2FA1-NCSJ-C01-0 in existing designs?

A: Yes. The FA1-NCSJ-C01-0 is a direct functional equivalent. Both parts are SMB Fakra female socket jacks with identical mounting type (free hanging, in-line), fastening type (latch lock), and cable group compatibility. No design modifications are required.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2FA1-NCSJ-C01-0 and FA1-NCSJ-C01-0 are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What cable types are compatible with both connectors?

A: Both parts support identical cable group compatibility: RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174. Cable selection is interchangeable between the two part numbers.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the temperature range of -40°C to 100°C, providing equivalent thermal performance for automotive and industrial RF applications.

Q: How many mating cycles are rated for each connector?

A: Both parts are rated for 100 mating cycles, providing equivalent mechanical durability and connection reliability.

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

A: The FA1-NCSJ-C01-0 is available in bulk packaging with significantly higher inventory (3004 units) compared to the 2FA1-NCSJ-C01-0 (790 units). For high-volume applications, the FA1-NCSJ-C01-0 provides better supply chain availability and bulk packaging economics.
