APH-BNCP-FJ Equivalent & Substitute Parts

Part Overview

The APH-BNCP-FJ is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between BNC Plug (Male Pin) and F Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 1 GHz and supports operating temperatures from -65°C to 165°C. The part is currently classified as Obsolete, necessitating identification of active equivalent alternatives for continued system integration and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APH-BNCP-FJ is determined by the following critical parameters:

Mandatory Matching Parameters:

• Adapter Series: BNC to F (conversion between connector types must remain identical)
• Adapter Type: Plug to Jack (gender configuration must be preserved)
• Center Gender: Female to Male (pin/socket orientation must match)
• Convert From (Adapter End): BNC Plug, Male Pin
• Convert To (Adapter End): F Jack, Female Socket
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Threaded
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Beryllium Copper
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature Range: -65°C ~ 165°C

Allowable Variation Parameters:

• Impedance: 50 Ohms or 75 Ohms (system-dependent; must be verified for application compatibility)
• Frequency - Max: Equal to or greater than 1 GHz
• Product Status: Active preferred over Obsolete
• RoHS/Compliance Status: Equal or higher compliance level acceptable

The substitute part 242154 maintains all mandatory matching parameters while introducing variations in impedance (75 Ohms vs. 50 Ohms) and frequency rating (2 GHz vs. 1 GHz). These variations represent enhanced or alternative specifications rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The APH-BNCP-FJ is classified as Obsolete. The substitute part 242154 is classified as Active and maintains full mechanical and electrical compatibility with identical adapter series, connector types, and physical construction. Selection of 242154 ensures continued procurement availability and manufacturer support.

Compliance and Certification

Both parts are RoHS compliant. The substitute part 242154 carries ROHS3 Compliant status, representing current regulatory compliance standards. The substitute also carries REACH Affected designation, indicating compliance with European chemical safety regulations. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Impedance Specification

The primary difference between APH-BNCP-FJ and 242154 is impedance rating: 50 Ohms versus 75 Ohms respectively. Selection between these specifications depends on system impedance requirements. The 50 Ohm specification is standard for RF/microwave systems, while 75 Ohm specification is standard for video and broadband applications. System design documentation must confirm impedance compatibility before substitution.

Frequency Rating

The substitute part 242154 provides a maximum frequency rating of 2 GHz compared to 1 GHz for the main part. This represents enhanced frequency capability and does not restrict application to systems operating at or below 1 GHz.

Inventory and Availability

The substitute part 242154 has 1209 pieces in stock compared to 971 pieces for the main part, providing improved procurement availability.

Frequently Asked Questions (FAQ)

Q: Can 242154 directly replace APH-BNCP-FJ in all applications?

A: Mechanical and physical compatibility is confirmed. Electrical compatibility depends on system impedance specification. If the original system requires 50 Ohm impedance, 242154 (75 Ohm) introduces impedance mismatch. If the system operates at 75 Ohm impedance or is impedance-agnostic, direct substitution is valid.

Q: What is the significance of the impedance difference between 50 Ohms and 75 Ohms?

A: Impedance mismatch between adapter and system components causes signal reflection and insertion loss. 50 Ohm adapters are used in RF/microwave systems; 75 Ohm adapters are used in video and broadband systems. Application documentation must specify required impedance.

Q: Why is APH-BNCP-FJ classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The substitute part 242154 is Active, meaning it is currently manufactured and available for procurement.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The substitute part 242154 carries ROHS3 Compliant status (current standard) and REACH Affected designation. Both share identical export control classifications (EAR99) and tariff codes (8536.69.4010).

Q: What is the packaging difference?

A: APH-BNCP-FJ packaging is not specified in available data. The substitute part 242154 is packaged in Bag format.

Q: Does the higher frequency rating of 242154 (2 GHz vs. 1 GHz) affect compatibility?

A: Higher frequency rating indicates enhanced capability and does not restrict use in systems operating at lower frequencies. A 2 GHz-rated adapter functions correctly in 1 GHz systems.

Q: Are the physical dimensions identical between the two parts?

A: Both parts share identical adapter series (BNC to F), mounting type (Free Hanging In-Line), fastening type (Bayonet Lock, Threaded), and construction materials (Brass body, Nickel finish, Beryllium Copper center contact, PTFE dielectric). Physical dimensions are equivalent.

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

A: Both APH-BNCP-FJ and 242154 operate across -65°C to 165°C, providing identical thermal performance specifications.
