SBC7538 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The SBC7538 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 a bayonet lock fastening mechanism. The part is currently active in production with 959 units in stock. Alternative equivalent parts may be required due to inventory constraints, specific packaging requirements, or application-specific performance needs within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBC7538 is permissible with the UPL2000-D1 based on the following critical parameters that define functional equivalence:

Core Electrical Parameters (Must Match):

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Fastening Type: Bayonet Lock
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB

Core Mechanical Parameters (Must Match):

• Mounting Type: Free Hanging (In-Line)
• Number of Ports: 1

Compliance Parameters (Must Match or Exceed):

• RoHS Status: RoHS Compliant or higher
• MSL Rating: 1 (Unlimited)

The UPL2000-D1 meets all mandatory electrical and mechanical requirements for direct substitution. Additional performance capabilities (higher frequency rating, extended operating temperature range, gold plating) represent enhancements that do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the SBC7538 and UPL2000-D1 are active production parts with full RoHS compliance. The SBC7538 carries RoHS Compliant certification, while the UPL2000-D1 carries the more recent ROHS3 Compliant certification. Both parts meet MSL Level 1 (Unlimited) moisture sensitivity requirements.

Selection between these parts should be based on:

1. Inventory Availability: SBC7538 has 959 units in stock; UPL2000-D1 has 908 units in stock.

2. Packaging Requirements: SBC7538 packaging is unspecified; UPL2000-D1 is supplied in Bulk packaging with included components (1 Connector, 1 Contact, 1 Sleeve).

3. Frequency Performance: SBC7538 is rated to 1 GHz; UPL2000-D1 is rated to 4 GHz. For applications operating below 1 GHz, both parts are equivalent. For applications requiring operation above 1 GHz up to 4 GHz, the UPL2000-D1 is required.

4. Operating Temperature: SBC7538 operating temperature is not specified; UPL2000-D1 is rated -40°C to 85°C. For applications requiring defined temperature performance, the UPL2000-D1 provides explicit specification.

5. Regulatory Compliance: Both parts meet ECCN EAR99 and HTSUS 8536.69.4010 classifications. The UPL2000-D1 carries REACH Affected status, which may be relevant for specific supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the UPL2000-D1 be used as a direct replacement for the SBC7538 in all applications?

A: Yes, the UPL2000-D1 meets all mandatory electrical and mechanical parameters of the SBC7538. Both connectors share identical impedance (75 Ohms), termination method (crimp), fastening type (bayonet lock), voltage rating (500 V), mating cycles (500), and insertion loss (0.2 dB). The UPL2000-D1 provides enhanced frequency capability (4 GHz vs. 1 GHz) and defined operating temperature range (-40°C to 85°C), which do not restrict substitution.

Q: What are the key differences between these two BNC connector plugs?

A: The primary differences are: (1) Frequency rating: SBC7538 to 1 GHz, UPL2000-D1 to 4 GHz; (2) Operating temperature: SBC7538 unspecified, UPL2000-D1 rated -40°C to 85°C; (3) Housing color: SBC7538 silver, UPL2000-D1 black; (4) Center contact material: SBC7538 unspecified, UPL2000-D1 brass with gold plating; (5) Dielectric material: SBC7538 unspecified, UPL2000-D1 PTFE; (6) Packaging: SBC7538 unspecified, UPL2000-D1 bulk with included components; (7) RoHS certification level: SBC7538 RoHS Compliant, UPL2000-D1 ROHS3 Compliant.

Q: Are there any impedance or electrical performance differences?

A: No. Both connectors are specified at 75 Ohms impedance with identical insertion loss of 0.2 dB, voltage rating of 500 V, and mating cycle rating of 500. Both use crimp termination for center contact and shield. Electrical performance is equivalent within the specified frequency ranges.

Q: What packaging considerations apply to substitution?

A: The SBC7538 packaging specification is not provided in the technical data. 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 substitution.

Q: Which part should be selected for high-frequency applications?

A: For applications requiring operation above 1 GHz, the UPL2000-D1 is specified to 4 GHz and is the appropriate selection. For applications operating at or below 1 GHz, both parts are electrically equivalent.

Q: Are there any compliance or regulatory differences?

A: Both parts carry ECCN EAR99 and HTSUS 8536.69.4010 classifications. The UPL2000-D1 carries REACH Affected status, which may apply to specific supply chain or regulatory requirements. The UPL2000-D1 carries ROHS3 Compliant certification, which supersedes the RoHS Compliant certification of the SBC7538.
