TE Connectivity 134959-1 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity 134959-1 is a BNC connector plug designed for 75-ohm coaxial cable applications. This component is a male pin, free-hanging (in-line) connector with crimp termination for both center contact and shield. The part operates across a frequency range up to 2 GHz and is rated for 500 volts with an operating temperature range of -65°C to 165°C.

The 134959-1 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. Active substitute components maintain the same electrical and mechanical specifications while offering improved availability and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 134959-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Impedance: 75 Ohms (required match)
• Frequency - Max: 2 GHz (required match)
• Voltage Rating: 500 V (required match)

Mechanical Compatibility Parameters:

• Connector Style: BNC (required match)
• Connector Type: Plug, Male Pin (required match)
• Mounting Type: Free Hanging (In-Line) (required match)
• Fastening Type: Bayonet Lock (required match)

Environmental & Compliance Parameters:

• Operating Temperature: -65°C ~ 165°C (required match)
• Dielectric Material: Polytetrafluoroethylene (PTFE) (required match)
• RoHS Status: ROHS3 Compliant (required match)

The substitute part 1-1337429-0 meets all critical electrical and mechanical parameters. The primary difference lies in the contact termination method (solder versus crimp) and center contact material composition, which do not affect functional equivalence when properly installed in their respective applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1337429-0 serves as the functional equivalent for the obsolete 134959-1 based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for current manufacturing and deployment environments.

Product Availability: The 134959-1 is classified as obsolete with limited inventory (909 pcs). The 1-1337429-0 is active with substantial inventory availability (64,420 pcs), providing long-term supply chain continuity.

Electrical Performance: Both connectors deliver equivalent electrical performance across all critical parameters: 75-ohm impedance, 2 GHz maximum frequency, 500-volt rating, and identical operating temperature range. The insertion loss differential (0.15 dB versus 0.2 dB) falls within acceptable tolerance for standard RF applications.

Mechanical Compatibility: Both connectors employ identical BNC plug configuration with bayonet lock fastening and free-hanging mounting, ensuring direct mechanical interchangeability in cable assemblies.

Termination Method Consideration: The primary technical distinction is the contact termination approach. The 134959-1 uses crimp termination while the 1-1337429-0 uses solder termination. Selection between these alternatives depends on the specific cable assembly process and equipment available in the manufacturing environment.

Frequently Asked Questions (FAQ)

Q: Can the 1-1337429-0 directly replace the 134959-1 in existing assemblies?

A: Yes. Both connectors share identical electrical specifications (75 ohms, 2 GHz, 500 V), mechanical configuration (BNC plug, bayonet lock, free-hanging), and environmental ratings (-65°C to 165°C). The primary consideration is the termination method: the 134959-1 requires crimp tooling while the 1-1337429-0 requires solder equipment.

Q: What is the significance of the different contact termination methods?

A: The 134959-1 uses crimp termination for the center contact, while the 1-1337429-0 uses solder termination. Both methods achieve equivalent electrical connections when properly executed. Selection depends on available assembly equipment and process specifications. Crimp termination typically offers faster assembly cycles, while solder termination may provide different mechanical characteristics in specific applications.

Q: Are there cable compatibility differences between these connectors?

A: The 134959-1 is specified for RG-59 and RG-62 cable groups. The 1-1337429-0 supports RG-59B, RG-62A, RG-140, and RG-210 cable groups. The 1-1337429-0 accommodates a broader range of cable specifications while maintaining backward compatibility with the original cable groups.

Q: What is the insertion loss difference between these parts?

A: The 134959-1 specifies 0.15 dB insertion loss while the 1-1337429-0 specifies 0.2 dB insertion loss. This 0.05 dB differential is negligible for standard RF applications and falls within typical system design margins.

Q: Why is the 134959-1 listed as obsolete?

A: The 134959-1 carries obsolete product status, indicating TE Connectivity has transitioned manufacturing to newer designs. The 1-1337429-0 represents the active equivalent, ensuring continued availability and manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both the 134959-1 and 1-1337429-0 are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: What is the inventory status for each part?

A: The 134959-1 has 909 pieces in stock (obsolete status). The 1-1337429-0 has 64,420 pieces in stock (active status), providing significantly greater availability for current and future applications.
