APH-NJ-BNCJ Equivalent & Substitute Parts

Part Overview

The APH-NJ-BNCJ is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between BNC Jack (Female Socket) and N Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 4 GHz and supports operating temperatures from -65°C to 165°C.

The APH-NJ-BNCJ is classified as an Obsolete product. Identification of equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and replacement applications where this adapter is specified in existing designs or installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APH-NJ-BNCJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack
• Conversion Type: Between Series
• Adapter Series: BNC to N
• Center Gender: Female to Female
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Threaded
• Frequency - Max: 4 GHz
• Operating Temperature Range: -65°C ~ 165°C
• Material Composition: Brass body with Nickel finish, Phosphor Bronze center contact with Gold plating, PTFE dielectric

The substitute part 242100 satisfies all mandatory matching parameters. The primary distinction between the main part and the substitute is the directional orientation of the conversion (BNC to N versus N to BNC) and the product status classification (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 242100 is functionally equivalent to the APH-NJ-BNCJ across all critical electrical and mechanical parameters. Both parts are manufactured by Amphenol RF and maintain identical impedance, frequency response, operating temperature range, and material specifications.

The APH-NJ-BNCJ is classified as Obsolete, while 242100 is classified as Active. The Active status of 242100 ensures continued manufacturing support, availability, and compliance with current regulatory standards. Part 242100 carries ROHS3 Compliant certification, representing compliance with the most current RoHS directive iteration, compared to the RoHS Compliant designation of the obsolete part.

Both parts satisfy EAR99 export control classification and maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling requirements.

The directional orientation difference between the two parts (BNC-to-N versus N-to-BNC conversion) does not affect functional equivalence in applications where adapter directionality is not constrained by system architecture. In bidirectional conversion scenarios, either part provides identical electrical performance.

Frequently Asked Questions (FAQ)

Q: Can 242100 directly replace APH-NJ-BNCJ in all applications?

A: Part 242100 is electrically and mechanically equivalent to APH-NJ-BNCJ. Both parts provide identical 50 Ohm impedance, 4 GHz frequency response, and operating temperature range. The primary difference is the conversion direction: APH-NJ-BNCJ converts from BNC Jack to N Jack, while 242100 converts from N Jack to BNC Jack. Selection depends on the specific connector orientation required in your system.

Q: What is the significance of the product status difference between Obsolete and Active?

A: The Obsolete status of APH-NJ-BNCJ indicates that Amphenol RF has discontinued manufacturing this part number. The Active status of 242100 confirms ongoing production and availability. For new designs or long-term procurement requirements, the Active part number is recommended to ensure supply chain continuity.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. Part 242100 carries ROHS3 Compliant certification, representing alignment with the latest RoHS directive requirements. Both parts are classified as EAR99 for export control purposes and carry identical MSL 1 ratings.

Q: What packaging is provided for each part?

A: APH-NJ-BNCJ is supplied without specified packaging designation. Part 242100 is supplied in Bag packaging. Current inventory levels are 824 pieces for APH-NJ-BNCJ and 849 pieces for 242100.

Q: Are the material specifications identical between the two parts?

A: Both parts use identical material specifications: Brass body with Nickel finish, Phosphor Bronze center contact with Gold plating, and PTFE dielectric material. These specifications ensure equivalent electrical performance and environmental durability across the operating temperature range of -65°C to 165°C.

Q: What fastening mechanisms are used?

A: Both parts employ Bayonet Lock and Threaded fastening types, ensuring secure mating and consistent electrical contact in free-hanging in-line configurations.
