Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1337549-0 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 75 Ohms
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Bayonet Lock
• Number of Ports: 1
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Voltage Rating: 500 V
• Mating Cycles: 500
• MSL: 1 (Unlimited)

Acceptable Variation Parameters:

• Contact Termination: Solder (main part) to Crimp (substitute parts) - both are acceptable termination methods for this connector category
• Frequency - Max: 2 GHz (main part) to 4 GHz (substitute parts) - higher frequency rating provides backward compatibility
• Center Contact Material: Brass (main part) to Phosphor Bronze (substitute parts) - both materials meet electrical requirements
• Cable Group: Different cable compatibility groups based on termination method differences

All three substitute parts (Amphenol RF 112568, 112969, and 112970) meet these criteria and are classified as active products with current RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes:

The three Amphenol RF BNC connector jacks (112568, 112969, and 112970) are direct functional equivalents to the TE Connectivity 1-1337549-0. All three substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain continuity.

Compliance Advantages:

All substitute parts carry ROHS3 compliance certification, representing an advancement over the RoHS compliance of the original part. This enhanced compliance status supports regulatory requirements for new product designs and system upgrades. All parts maintain EAR99 export classification and identical HTSUS tariff codes, ensuring consistent regulatory treatment.

Termination Method Consideration:

The primary distinction between the original part and substitutes is the contact termination method. The TE Connectivity 1-1337549-0 employs solder termination, while all three Amphenol RF alternatives utilize crimp termination. Both termination methods are standard for BNC connector applications and provide equivalent electrical performance. Selection between solder and crimp termination depends on assembly process requirements and cable preparation capabilities within the implementation environment.

Frequency Rating Enhancement:

The substitute parts provide a maximum frequency rating of 4 GHz compared to the original part's 2 GHz specification. This higher frequency capability ensures compatibility with applications operating at or below the original 2 GHz specification while providing additional performance margin for future system requirements.

Cable Compatibility:

Each substitute part supports different cable group specifications based on termination method and contact material composition. Amphenol RF 112568 supports RG-122, 180, 180A, 180B, 195, Belden 1855, and 1865A cables. Amphenol RF 112969 supports AT&T 735, 735A, and Belden 735A1 cables. Amphenol RF 112970 supports AT&T 734, 734A, and Belden 1505A cables. Cable selection must align with the specific application requirements and available cable inventory.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112568, 112969, or 112970 directly replace the TE Connectivity 1-1337549-0 in existing assemblies?

A: Yes. All three Amphenol RF parts are functionally equivalent across all critical electrical and mechanical parameters. The primary difference is the contact termination method (crimp versus solder). If the assembly process supports crimp termination, direct substitution is possible. If the assembly process requires solder termination, the termination method must be adapted to the crimp-based design of the substitute parts.

Q: What is the difference between the three Amphenol RF substitute parts?

A: Amphenol RF 112568, 112969, and 112970 are electrically and mechanically identical BNC connector jacks with 75 ohm impedance, panel mount bulkhead configuration, and crimp termination. The primary differences are the supported cable groups: 112568 supports RG-series cables, 112969 supports AT&T 735-series cables, and 112970 supports AT&T 734-series cables. Selection depends on the specific cable type used in the application.

Q: Why do the substitute parts have a higher frequency rating (4 GHz) than the original part (2 GHz)?

A: The higher frequency rating of the substitute parts reflects the design specifications of the Amphenol RF connector series. This higher rating provides additional performance margin and ensures compatibility with applications operating at the original 2 GHz specification. The higher frequency capability does not affect compatibility with lower-frequency applications.

Q: Are there any compliance or regulatory differences between the original part and the substitutes?

A: The substitute parts carry ROHS3 compliance certification, which represents an advancement over the RoHS compliance of the original TE Connectivity part. All parts maintain identical EAR99 export classification and HTSUS tariff codes. The enhanced compliance status of the substitute parts supports current regulatory requirements for new product designs.

Q: What is the impact of changing from solder to crimp contact termination?

A: Both solder and crimp termination methods are standard for BNC connector applications and provide equivalent electrical performance. The change requires adaptation of the assembly process to accommodate crimp termination instead of solder termination. Crimp termination typically offers advantages in assembly speed and consistency compared to solder-based approaches.

Q: Are the substitute parts available in the same packaging as the original part?

A: Amphenol RF 112568 and 112970 are packaged in bags. Amphenol RF 112969 packaging information is not specified in the available data. The original TE Connectivity part packaging is not specified. Packaging differences do not affect electrical or mechanical compatibility and are primarily relevant to inventory management and handling procedures.

Q: What is the center contact material difference, and does it affect performance?

A: The original TE Connectivity part uses brass center contacts, while the Amphenol RF substitutes use phosphor bronze. Both materials meet the electrical requirements for 75 ohm BNC connectors and provide equivalent performance in RF applications. The material difference reflects design variations between manufacturers and does not impact functional compatibility.

Q: Can I use these substitute parts in new designs, or are they only for replacement of obsolete parts?

A: The Amphenol RF substitute parts are classified as active products with current manufacturing status. They are suitable for both replacement of obsolete TE Connectivity parts and for incorporation into new product designs. The active status ensures long-term availability and supply chain continuity for ongoing production requirements.
