TE Connectivity 1663751-1 BNC Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1663751-1 is an active BNC connector plug designed for 50 ohm coaxial applications. This male pin connector features crimp termination for the center contact and push-on shield termination, configured for panel mount bulkhead installation on the front side with snap-on fastening. The connector accommodates RG-58 cable group and supports 500 mating cycles. This part is actively manufactured and stocked with 860 units available in new original condition.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's functional requirements, enabling direct replacement in compatible applications while maintaining system performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the TE Connectivity 1663751-1 is based on the following critical parameters that determine functional compatibility:

Connector Style and Type: Both the main part and substitute must maintain BNC connector architecture with male pin configuration to ensure mechanical mating compatibility.

Contact Termination Method: Crimp termination is required for both parts to support equivalent cable attachment and electrical performance.

Impedance Specification: The 50 ohm impedance rating is fundamental to RF signal integrity and system matching. Substitute parts must maintain this specification.

Mounting Configuration: Panel mount capability with bulkhead installation is essential for the intended application context.

Electrical and Environmental Compliance: RoHS3 compliance and MSL 1 rating ensure regulatory alignment and reliability in storage and deployment.

Mating Cycle Rating: The 500 mating cycle specification establishes durability expectations for connector engagement cycles.

The identified substitute part (Amphenol RF 034-1037) presents a different impedance specification (75 ohms versus 50 ohms) and alternative mounting configuration (free hanging in-line versus panel mount bulkhead). These differences indicate this part operates under distinct electrical and mechanical parameters and does not qualify as a direct functional substitute for the TE Connectivity 1663751-1 in applications requiring 50 ohm panel mount configuration.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1663751-1 remains the specified component for applications requiring 50 ohm impedance with panel mount bulkhead configuration. Both the main part and the identified alternative (Amphenol RF 034-1037) maintain active product status and full RoHS3 compliance with MSL 1 rating, confirming current manufacturing support and regulatory alignment.

The Amphenol RF 034-1037 operates under distinct electrical parameters (75 ohm impedance) and mechanical configuration (free hanging in-line mounting), making it unsuitable as a direct substitute in systems designed for the TE Connectivity 1663751-1 specifications.

Selection of the TE Connectivity 1663751-1 is appropriate for applications where 50 ohm impedance and panel mount bulkhead installation are system requirements. The part's active status, 860 unit inventory availability, and full compliance certifications support procurement for current production and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 034-1037 replace the TE Connectivity 1663751-1 in my application?

A: No. The Amphenol RF 034-1037 operates at 75 ohm impedance with free hanging in-line mounting, whereas the TE Connectivity 1663751-1 is specified for 50 ohm impedance with panel mount bulkhead configuration. These differences in impedance and mounting type make direct substitution incompatible with systems designed for the TE Connectivity part.

Q: What cable groups are compatible with the TE Connectivity 1663751-1?

A: The TE Connectivity 1663751-1 accommodates RG-58 cable group. Cable selection must align with this specification to ensure proper termination and electrical performance.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the TE Connectivity 1663751-1 and Amphenol RF 034-1037 are RoHS3 compliant with MSL 1 rating and EAR99 ECCN classification, confirming regulatory alignment for current applications.

Q: What is the difference between crimp and push-on shield termination?

A: The TE Connectivity 1663751-1 uses push-on shield termination, where the shield slides onto the connector body. The Amphenol RF 034-1037 uses crimp shield termination, requiring mechanical compression of the shield onto the connector. These termination methods are distinct and affect assembly procedures and mechanical performance.

Q: How many mating cycles are supported by the TE Connectivity 1663751-1?

A: The TE Connectivity 1663751-1 supports 500 mating cycles, establishing the expected durability for connector engagement and disengagement operations.

Q: What is included in the TE Connectivity 1663751-1 package?

A: The package includes 4 pieces: 1 connector, 1 contact, 1 lockwasher, and 1 nut, providing the complete assembly components for panel mount installation.
