TO259-213 UHF Connector Plug Equivalent & Substitute Parts

Part Overview

The TO259-213 is a UHF connector plug manufactured by Cinch Connectivity Solutions, designed as a male pin non-constant impedance coaxial connector with solder cup termination. This component is classified as an active product and is suitable for RF applications requiring threaded fastening in free-hanging inline configurations. The part is compatible with RG-213 cable groups and operates at frequencies up to 300 MHz with a rated mating cycle life of 500 cycles.

Substitute parts become necessary when the original TO259-213 reaches end-of-life status, when inventory constraints occur, or when application requirements necessitate enhanced performance characteristics such as higher frequency capability or alternative termination methods.

Substitute Part Grouping Explanation

Substitute parts for the TO259-213 are identified based on matching core electrical and mechanical parameters that define functional equivalence in UHF connector applications. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Connector Style: UHF (required match)
• Connector Type: Plug, Male Pin (required match)
• Mounting Type: Free Hanging (In-Line) (required match)
• Fastening Type: Threaded (required match)
• Number of Ports: 1 (required match)
• Impedance: Non-Constant (required match)

Secondary Compatibility Parameters:

• Cable Group compatibility (RG-213 compatibility required or broader cable group support)
• Mating Cycles: 500 (minimum requirement)
• Body Material: Brass (standard for UHF connectors)

The substitute part 1-1337474-0 from TE Connectivity AMP Connectors meets all primary matching parameters. While this part features push-on contact termination rather than solder cup termination, it maintains electrical and mechanical compatibility through equivalent UHF connector architecture, identical mounting configuration, and superior frequency capability (500 MHz versus 300 MHz). The substitute supports RG-213 within its broader cable group compatibility range.

Parameter Comparison

Engineering Selection Recommendations

TO259-213 Selection Criteria: The TO259-213 remains the primary component choice for new designs and applications requiring active product status with ongoing manufacturer support. This part is suitable for RF applications operating at frequencies up to 300 MHz with solder cup termination for permanent cable connections. The active product status ensures continued availability and supply chain stability.

1-1337474-0 Selection Criteria: The 1-1337474-0 substitute is classified as obsolete and should be selected only when the TO259-213 is unavailable or when the application specifically requires the enhanced frequency capability (500 MHz) and push-on termination method. This substitute demonstrates RoHS compliance and REACH affected status, providing environmental regulatory alignment. The push-on contact termination offers field-replaceable cable connection capability, contrasting with the permanent solder cup design of the main part. The broader cable group support (RG-8A, 9B, 213, 214) provides expanded application flexibility.

Compliance Considerations: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, ensuring consistent export and tariff treatment. The substitute part's RoHS compliance status should be evaluated against specific application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1-1337474-0 directly replace the TO259-213 in existing installations?

A: Direct replacement is mechanically and electrically feasible due to matching UHF connector architecture, threaded fastening, and free-hanging inline mounting. However, the termination method differs: the TO259-213 uses solder cup termination while the 1-1337474-0 uses push-on termination. Cable connection methodology must be adapted accordingly.

Q: What is the significance of the frequency rating difference between these parts?

A: The TO259-213 operates at frequencies up to 300 MHz, while the 1-1337474-0 operates at frequencies up to 500 MHz. For applications operating below 300 MHz, both parts perform equivalently. For applications requiring frequencies between 300 MHz and 500 MHz, only the 1-1337474-0 is suitable.

Q: Why is the 1-1337474-0 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part. While existing inventory may be available, long-term supply cannot be guaranteed. The TO259-213 active status provides superior supply chain reliability for ongoing production requirements.

Q: Are there cable group compatibility considerations?

A: The TO259-213 is specified for RG-213 cable group. The 1-1337474-0 supports a broader range including RG-8A, 9B, 213, and 214. Both parts are compatible with RG-213, ensuring cable compatibility in substitution scenarios.

Q: What termination method should be selected for permanent versus field-replaceable connections?

A: The TO259-213 solder cup termination creates permanent cable connections suitable for fixed installations. The 1-1337474-0 push-on termination allows field-replaceable cable connections without soldering, providing maintenance flexibility at the cost of permanent connection security.

Q: Do both parts meet the same regulatory classifications?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The 1-1337474-0 additionally specifies RoHS compliance and REACH affected status, providing enhanced environmental regulatory documentation for applications requiring these certifications.
