Amphenol RF 2FA1-NDSJ-C01-0 Equivalent & Substitute Parts

Part Overview

The Amphenol RF 2FA1-NDSJ-C01-0 is an SMB Fakra connector jack designed for coaxial RF applications requiring 50-ohm impedance. This female socket connector features crimp termination for both center contact and shield, supporting cable groups including RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174. The connector operates across a frequency range up to 6 GHz with a maximum operating temperature of 100°C and maintains an insertion loss of 0.3 dB. The product is currently active in production and maintains full RoHS3 and REACH compliance. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate packaging or material specification variations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Compatibility Parameters:

• Impedance: 50 Ohms (mandatory)
• Frequency maximum: 6 GHz (mandatory)
• Insertion loss: 0.3 dB (mandatory)
• Connector type: Jack, Female Socket (mandatory)

Mechanical Compatibility Parameters:

• Connector style: SMB, Fakra (mandatory)
• Contact termination: Crimp (mandatory)
• Shield termination: Crimp (mandatory)
• Mounting type: Free Hanging (In-Line) (mandatory)
• Fastening type: Latch Lock (mandatory)
• Number of ports: 1 (mandatory)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 100°C (mandatory)
• Mating cycles: 100 (mandatory)
• RoHS3 compliance (mandatory)
• REACH compliance (mandatory)
• Moisture sensitivity level: 1 (Unlimited) (mandatory)

Substitute parts must match all mandatory parameters. Variations in center contact material, body material, body finish, and included component quantities do not affect substitution eligibility provided all electrical, mechanical, and environmental specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the 2FA1-NDSJ-C01-0 and FA1-NDSJ-C01-0 are active production parts manufactured by Amphenol RF and maintain full compliance with RoHS3 and REACH regulations. Both connectors satisfy identical electrical performance specifications including 50-ohm impedance, 6 GHz maximum frequency, and 0.3 dB insertion loss. Both support the same cable groups and operate across the identical temperature range of -40°C to 100°C.

The primary distinction between these parts lies in packaging and included component quantities. The 2FA1-NDSJ-C01-0 is supplied with three components (connector, contact, ferrule), while the FA1-NDSJ-C01-0 includes five components (connector, contact, ferrule, housing, locking clip). Additionally, the 2FA1-NDSJ-C01-0 features a zinc die-cast body with phosphor bronze center contact material, whereas the FA1-NDSJ-C01-0 uses a brass body with beryllium copper center contact material.

Selection between these parts should be based on packaging requirements, inventory availability, and specific assembly needs. Both parts are suitable for direct substitution in applications requiring SMB Fakra female socket connectors with crimp termination and 50-ohm impedance.

Frequently Asked Questions (FAQ)

Q: Can the FA1-NDSJ-C01-0 be used as a direct replacement for the 2FA1-NDSJ-C01-0 in existing designs?

A: Yes. Both connectors meet identical electrical and mechanical specifications including impedance, frequency range, insertion loss, termination type, and mounting configuration. The FA1-NDSJ-C01-0 is electrically and mechanically compatible with applications designed for the 2FA1-NDSJ-C01-0.

Q: What are the differences in material composition between these two parts?

A: The 2FA1-NDSJ-C01-0 uses a zinc die-cast body with phosphor bronze center contact material. The FA1-NDSJ-C01-0 uses a brass body with beryllium copper center contact material. Both maintain identical gold plating on the center contact and nickel body finish. These material variations do not affect electrical performance or compliance status.

Q: Why does the FA1-NDSJ-C01-0 include additional components?

A: The FA1-NDSJ-C01-0 is supplied with five components including a housing and locking clip, while the 2FA1-NDSJ-C01-0 includes three components. This difference reflects packaging variations and may provide assembly convenience depending on application requirements.

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both connectors support frequencies up to 6 GHz with 0.3 dB insertion loss and are designed for RF coaxial applications. Both maintain 50-ohm impedance across their operating frequency range.

Q: What is the significance of the Code D feature designation?

A: Code D is a feature designation specific to Fakra connectors that identifies the connector variant. Both the 2FA1-NDSJ-C01-0 and FA1-NDSJ-C01-0 share this Code D designation, confirming compatibility with Code D mating interfaces.

Q: Do both parts support the same cable types?

A: Yes. Both connectors support identical cable groups: RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174. Cable compatibility is identical between the two parts.

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life with no special moisture control requirements during storage or handling.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both the 2FA1-NDSJ-C01-0 and FA1-NDSJ-C01-0 are RoHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic components.
