TE Connectivity 225973-1 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity 225973-1 is a BNC connector plug designed for coaxial RF applications. This male pin connector features a right-angle crimp termination, 50-ohm impedance, and operates across the RG-58 cable group. The part is currently in active product status with 921 units in stock.

The 225973-1 serves as the primary reference for identifying compatible substitute components. Substitutes are necessary when the active part becomes unavailable, when inventory constraints require alternative sourcing, or when design specifications permit equivalent electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 225973-1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Impedance (50 Ohms), frequency maximum (4 GHz), voltage rating (500 V), and insertion loss (0.2 dB) must remain constant across all substitutes.

Mechanical Parameters: Connector style (BNC), connector type (Plug, Male Pin), mounting type (Free Hanging, Right Angle), and fastening type (Bayonet Lock) must be identical.

Termination Parameters: Both contact termination and shield termination must be crimp-based.

Cable Compatibility: The substitute must support the RG-58 cable group (including 58A, 58B, 58C variants).

Environmental Parameters: Operating temperature range (-55°C ~ 85°C) and mating cycle rating (500) must be maintained.

The substitute part 225974-1 meets all these criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

Primary Selection: TE Connectivity 225973-1

The 225973-1 is the recommended primary choice for new designs and applications. This part maintains active product status, ensuring long-term availability and supply chain stability. Current inventory of 921 units supports immediate procurement. The silver body finish provides standard RF connector aesthetics and performance characteristics.

Substitute Selection: TE Connectivity 225974-1

The 225974-1 is classified as a parametric equivalent and serves as a substitute when the primary part becomes unavailable. All critical electrical and mechanical parameters are identical to the 225973-1. The part is currently marked as obsolete, indicating limited future availability. Current inventory of 788 units is available for immediate delivery.

Distinction Between Parts:

The primary difference between these parts is the body finish specification. The 225973-1 features a silver finish, while the 225974-1 features a nickel finish. Both finishes are applied to the brass body material and do not alter the electrical performance, impedance characteristics, or RF transmission properties. The finish difference is cosmetic and does not affect functional compatibility in RF applications.

Compliance Considerations:

Both parts carry identical RoHS non-compliant status, ECCN classification (EAR99), and HTSUS code (8536.69.4010). Neither part requires special handling or compliance modifications for standard RF applications. Moisture sensitivity level (MSL) is 1 (Unlimited) for both parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 225974-1 be used as a direct replacement for the 225973-1?

A: Yes. The 225974-1 is a parametric equivalent with identical electrical and mechanical specifications. All critical parameters including impedance, frequency response, voltage rating, termination type, and cable compatibility are identical. The only difference is the body finish (nickel versus silver), which does not affect RF performance or functional compatibility.

Q: What is the significance of the body finish difference between these parts?

A: The body finish (silver on 225973-1 versus nickel on 225974-1) is a cosmetic specification that does not impact electrical performance, impedance, or RF transmission characteristics. Both finishes are applied to the same brass body material and provide equivalent corrosion resistance and durability in standard operating environments.

Q: Why is the 225974-1 marked as obsolete if it is functionally equivalent?

A: Product status reflects manufacturing and supply chain decisions by TE Connectivity. The obsolete designation indicates that the 225974-1 is no longer in active production. However, existing inventory remains available for purchase. For new designs requiring long-term supply assurance, the active 225973-1 is the preferred choice.

Q: Are these parts compatible with the same cable types?

A: Yes. Both the 225973-1 and 225974-1 support the RG-58 cable group, including RG-58, RG-58A, RG-58B, and RG-58C variants. Cable compatibility is identical across both parts.

Q: What is the maximum frequency rating for these connectors?

A: Both parts are rated for a maximum frequency of 4 GHz. This specification applies to the 225973-1 and 225974-1 equally.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for an operating temperature range of -55°C to 85°C. This range covers standard industrial and commercial RF applications. Applications requiring extended temperature ranges beyond this specification require alternative connector designs.

Q: What is the mating cycle rating for these connectors?

A: Both the 225973-1 and 225974-1 are rated for 500 mating cycles. This specification defines the expected number of connect/disconnect operations before performance degradation occurs under normal operating conditions.

Q: Are there any RoHS compliance considerations for these parts?

A: Both parts are marked as RoHS non-compliant. This designation indicates that the parts contain materials or substances that exceed RoHS limits. Applications subject to RoHS regulations require alternative connector designs that meet RoHS compliance requirements.

Q: What termination method is used for these connectors?

A: Both parts use crimp termination for both the center contact and shield. Crimp termination requires specialized tooling and training to ensure proper connection integrity. No soldering is involved in the termination process.

Q: What is the voltage rating for these connectors?

A: Both the 225973-1 and 225974-1 are rated for 500 volts. This specification defines the maximum voltage that can be safely applied across the connector without risk of electrical breakdown or arcing.
