SBC7501 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The SBC7501 is a BNC connector plug manufactured by Winchester Interconnect, designed for coaxial RF applications requiring 75 ohm impedance. This male pin connector features crimp termination for both center contact and shield, with free hanging (in-line) mounting configuration and bayonet lock fastening. The part is currently active in production with 1092 pieces in stock inventory. Alternative equivalent parts may be required due to supply chain considerations, specific packaging requirements, or application-specific performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBC7501 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC (bayonet lock coupling mechanism)
• Connector Type: Plug, Male Pin (gender and pin configuration)
• Impedance: 75 Ohms (electrical characteristic for signal integrity)
• Contact Termination: Crimp (connection method for center conductor)
• Shield Termination: Crimp (connection method for outer shield)
• Mounting Type: Free Hanging (In-Line) (physical installation configuration)
• Fastening Type: Bayonet Lock (mechanical coupling interface)
• Voltage Rating: 500 V (electrical safety specification)
• Insertion Loss: 0.2 dB (RF performance specification)
• Mating Cycles: 500 (mechanical durability specification)

The UPL2000-D1 manufactured by Cinch Connectivity Solutions Trompeter meets all mandatory matching parameters and qualifies as a direct substitute for the SBC7501.

Parameter Comparison

Engineering Selection Recommendations

Both the SBC7501 and UPL2000-D1 are active production parts with equivalent electrical and mechanical specifications. Selection between these parts should be based on the following factors:

SBC7501 (Winchester Interconnect):

• RoHS Compliant status
• Current inventory: 1092 pieces
• Maximum frequency: 1 GHz
• Packaging: Not specified

UPL2000-D1 (Cinch Connectivity Solutions Trompeter):

• ROHS3 Compliant status (higher compliance standard)
• Current inventory: 908 pieces
• Maximum frequency: 4 GHz (extended frequency capability)
• Packaging: Bulk
• Includes: 3 pcs - 1 Connector, 1 Contact, 1 Sleeve
• Operating Temperature: -40°C ~ 85°C (specified range)
• Center Contact Material: Brass with Gold plating
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• REACH Status: REACH Affected

Both parts satisfy the mandatory substitution criteria. The UPL2000-D1 provides extended frequency performance (4 GHz versus 1 GHz) and ROHS3 compliance, while the SBC7501 maintains standard RoHS compliance. Selection should align with application frequency requirements and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the UPL2000-D1 be used as a direct replacement for the SBC7501 in existing designs?

A: Yes. Both connectors share identical BNC plug configuration, 75 ohm impedance, crimp termination for center contact and shield, free hanging mounting, bayonet lock fastening, 500 V voltage rating, 0.2 dB insertion loss, and 500 mating cycles. The UPL2000-D1 exceeds the SBC7501 in maximum frequency capability (4 GHz versus 1 GHz).

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Maximum frequency: UPL2000-D1 operates to 4 GHz while SBC7501 operates to 1 GHz; (2) RoHS compliance level: UPL2000-D1 is ROHS3 compliant versus RoHS compliant for SBC7501; (3) Packaging: UPL2000-D1 is supplied in bulk with included contact and sleeve components; (4) Operating temperature range specified for UPL2000-D1 (-40°C ~ 85°C); (5) Center contact plating: UPL2000-D1 features gold plating; (6) Dielectric material: UPL2000-D1 specifies PTFE.

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

A: Yes. Both connectors are specified for Comm/Scope 7538 cable group, indicating compatibility with the same cable specifications.

Q: What is the significance of the higher maximum frequency rating on the UPL2000-D1?

A: The UPL2000-D1 maximum frequency of 4 GHz provides extended operational capability for higher frequency applications. The SBC7501 is rated to 1 GHz. Applications operating below 1 GHz are compatible with both parts; applications between 1 GHz and 4 GHz require the UPL2000-D1.

Q: Does the gold plating on the UPL2000-D1 center contact affect substitution compatibility?

A: No. Gold plating on the center contact is a material enhancement that does not affect electrical or mechanical compatibility. Both parts maintain 75 ohm impedance and 0.2 dB insertion loss specifications.

Q: What packaging considerations apply to these parts?

A: The SBC7501 packaging is not specified in available documentation. The UPL2000-D1 is supplied in bulk packaging and includes three components: 1 connector, 1 contact, and 1 sleeve. Verify packaging requirements for your application before selection.

Q: Are both parts suitable for outdoor or weatherproof applications?

A: The SBC7501 specifies weatherproof ingress protection. The UPL2000-D1 does not specify ingress protection rating in available documentation. For applications requiring weatherproof performance, verify the UPL2000-D1 environmental specifications with the manufacturer.
