Amphenol RF 122502 TNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 122502 is an active TNC connector plug designed for RF coaxial applications. This male pin connector features a right-angle solder termination with 50 ohm impedance, suitable for free-hanging in-line mounting configurations. The connector operates at frequencies up to 11 GHz and is compatible with standard RG-series coaxial cables including RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393.

The 122502 maintains active product status with 825 units currently in stock. Substitute part identification becomes necessary when inventory constraints occur, when alternative sourcing is required, or when procurement lead times necessitate component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 122502 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Impedance (50 Ohms), frequency maximum rating (11 GHz), voltage rating (500 V), and insertion loss (0.18 dB) must be identical.

Mechanical Parameters: Connector style (TNC), connector type (Plug, Male Pin), mounting configuration (Free Hanging In-Line, Right Angle), and contact termination method (Solder) must be identical.

Material and Finish Specifications: Center contact material (Brass), center contact plating (Gold), body material (Brass), body finish (Nickel), and dielectric material (Polytetrafluoroethylene/PTFE) must be identical.

Compatibility Parameters: Cable group compatibility must encompass the same RG-series cable types. Fastening type (Threaded) and number of ports (1) must be identical.

Compliance and Certification: RoHS3 compliance, REACH affected status, and MSL rating (1 - Unlimited) must be maintained.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 122503 is a direct parametric equivalent to the 122502. Both components are manufactured by Amphenol RF and maintain identical electrical, mechanical, and material specifications across all critical parameters.

Functional Interchangeability: The 122503 operates identically to the 122502 in all RF coaxial applications requiring TNC male plug connectors with 50 ohm impedance, right-angle solder termination, and compatibility with standard RG-series cables.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 122503 be used as a direct replacement for the 122502 in existing designs?

A: Yes. The 122503 is a parametric equivalent with identical electrical specifications (50 ohms, 11 GHz maximum frequency, 0.18 dB insertion loss), mechanical configuration (TNC plug, male pin, right-angle solder), and material composition (brass body with nickel finish, gold-plated brass center contact, PTFE dielectric). No design modifications are required.

Q: Are there any differences in cable compatibility between these two connectors?

A: No. Both the 122502 and 122503 are compatible with identical cable groups: RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393.

Q: Do both connectors meet the same regulatory and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH affected, classified under ECCN EAR99, and carry the same HTSUS code (8536.69.4010). Both maintain MSL rating 1 (Unlimited moisture sensitivity level).

Q: What is included in the packaging for each connector?

A: Both the 122502 and 122503 are supplied with three components: one connector, one end cap, and one ferrule.

Q: Are there any performance differences in insertion loss or mating cycle ratings?

A: No. Both connectors specify identical insertion loss of 0.18 dB and identical mating cycle rating of 500 cycles.

Q: Can these connectors be used interchangeably in RF applications operating at frequencies up to 11 GHz?

A: Yes. Both connectors are rated for maximum frequency operation of 11 GHz and maintain identical impedance (50 ohms) and insertion loss characteristics across this frequency range.

Q: What is the voltage rating for both connectors?

A: Both the 122502 and 122503 are rated for 500 volts.
