APH-NP-UHFJ Equivalent & Substitute Parts

Part Overview

The APH-NP-UHFJ is a coaxial adapter connector manufactured by Amphenol RF that converts between N Plug (male pin) and UHF Jack (female socket) configurations. This adapter operates at 50 Ohms impedance and is designed for RF applications requiring series conversion between N and UHF connector types.

The APH-NP-UHFJ is classified as Obsolete. Locating equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this adapter. Active production alternatives with identical or superior electrical specifications are available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APH-NP-UHFJ is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: N to UHF
• Center Gender: Female to Male
• Convert From: N Plug, Male Pin
• Convert To: UHF Jack, Female Socket
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Material: Brass
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Operating Temperature: -65°C ~ 165°C

The substitute part 242155 satisfies all mandatory matching parameters and is therefore a direct functional equivalent for the APH-NP-UHFJ.

Engineering Selection Recommendations

APH-NP-UHFJ (Obsolete): This part is no longer in active production. While 1006 units remain in stock, the obsolete status indicates limited future availability. Selection of this part is appropriate only when existing inventory must be maintained or when legacy system documentation specifically requires this part number.

242155 (Active Substitute): This part is the recommended selection for new designs and applications requiring N to UHF adapter functionality. The part is in active production status with 827 units currently in stock. It meets all electrical and mechanical specifications of the APH-NP-UHFJ while offering superior frequency capability (2.5 GHz versus 300 MHz). Compliance certifications include ROHS3 Compliant and REACH Affected status, providing enhanced regulatory alignment for current manufacturing standards.

Both parts are manufactured by Amphenol RF and share identical mechanical interfaces, materials, and core electrical specifications. The 242155 provides extended frequency performance and active production support, making it the preferred choice for new applications and component replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can 242155 be used as a direct replacement for APH-NP-UHFJ in existing applications?

A: Yes. Both parts are mechanically and electrically identical across all critical parameters including adapter type, connector series, impedance, materials, and operating temperature range. The 242155 is a direct functional equivalent.

Q: What is the primary difference between these two parts?

A: The APH-NP-UHFJ is classified as Obsolete with a maximum frequency rating of 300 MHz, while 242155 is Active production with a maximum frequency rating of 2.5 GHz. The 242155 also carries ROHS3 Compliant certification compared to RoHS Compliant for the APH-NP-UHFJ.

Q: Are there any mechanical compatibility issues when substituting 242155 for APH-NP-UHFJ?

A: No. Both parts feature identical mounting type (Free Hanging In-Line), fastening type (Threaded, Threaded), and body materials (Brass with Nickel finish). Physical and mechanical interfaces are equivalent.

Q: Does the higher frequency rating of 242155 affect compatibility with systems designed for APH-NP-UHFJ?

A: No. The 242155 operates at the same impedance (50 Ohms) and maintains all electrical characteristics required for N to UHF conversion. The extended frequency capability of 2.5 GHz is a performance enhancement that does not compromise compatibility with applications rated for 300 MHz operation.

Q: What is the packaging difference between these parts?

A: APH-NP-UHFJ packaging is not specified in available documentation. The 242155 is supplied in Bag packaging.

Q: Are both parts RoHS compliant?

A: Yes. APH-NP-UHFJ carries RoHS Compliant certification. The 242155 carries ROHS3 Compliant certification, which represents a more current regulatory standard.

Q: Which part should be selected for new designs?

A: The 242155 is the appropriate selection for new designs. It is in active production, carries current compliance certifications (ROHS3, REACH Affected), and provides superior frequency performance while maintaining full compatibility with the APH-NP-UHFJ specification.
