APH-NP-BNCP Equivalent & Substitute Parts

Part Overview

The APH-NP-BNCP is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between BNC Plug (Male Pin) and N Plug (Male Pin) interfaces. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 4 GHz and supports a temperature range of -55°C to 165°C. The part is classified as Obsolete, necessitating identification of active equivalent components for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APH-NP-BNCP is determined by equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Plug
• Conversion Type: Between Series
• Adapter Series: BNC to N
• Center Gender: Male to Male
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock, Threaded
• Frequency - Max: 4 GHz
• Center Contact Plating: Gold
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Brass

The substitute part 242122 maintains functional equivalence across all mandatory parameters. Differences exist in dielectric material composition and operating temperature range, which reflect design variations between the obsolete and active product lines.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 242122 is an active product with current manufacturing status, whereas the APH-NP-BNCP is classified as Obsolete. Both parts are RoHS compliant, with 242122 meeting the more recent ROHS3 standard. The substitute maintains all critical RF and mechanical parameters required for BNC-to-N adapter functionality.

Selection of 242122 is appropriate for applications operating within the -40°C to 85°C temperature range. Applications requiring the extended low-temperature performance of the original part (-55°C minimum) must evaluate the operating environment against the substitute's lower temperature limit.

Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and are manufactured from equivalent materials with identical impedance, frequency, and connector specifications.

Frequently Asked Questions (FAQ)

Q: Can 242122 directly replace APH-NP-BNCP in all applications?

A: The substitute part 242122 maintains functional equivalence for RF and mechanical parameters. Compatibility depends on the operating temperature range of the application. If the system operates above -40°C and below 85°C, direct substitution is supported. Applications requiring operation below -40°C or above 85°C must evaluate thermal requirements against the substitute's specifications.

Q: What is the difference in dielectric material between these parts?

A: The APH-NP-BNCP uses Polytetrafluoroethylene (PTFE) dielectric material, while 242122 uses Polyoxymethylene (POM) Acetal. Both materials are suitable for 50 Ohm coaxial adapter applications at 4 GHz maximum frequency.

Q: Are both parts RoHS compliant?

A: Yes. The APH-NP-BNCP is RoHS Compliant, and 242122 is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the packaging difference?

A: The APH-NP-BNCP packaging is not specified in available documentation. The substitute part 242122 is supplied in Bag packaging.

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

A: The APH-NP-BNCP has been discontinued by the manufacturer. The active equivalent 242122 is the current production alternative for BNC-to-N adapter applications.

Q: Are the connector genders the same on both parts?

A: Yes. Both APH-NP-BNCP and 242122 feature Male-to-Male center gender configuration, maintaining identical mating interface specifications.
