VBM201-75 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The VBM201-75 is an active BNC connector jack manufactured by Cinch Connectivity Solutions, designed for 75 Ohm coaxial applications. This right-angle, panel-mount connector features solder termination for both center contact and shield, with through-hole PCB mounting. The connector is rated for 1 GHz maximum frequency and includes a bayonet lock fastening mechanism. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the VBM201-75 are classified based on strict alignment with the following critical parameters: connector style (BNC), connector type (jack, female socket), impedance (75 Ohms), mounting configuration (panel mount, through hole, right angle), contact and shield termination method (solder), fastening type (bayonet lock), and frequency rating (1 GHz maximum). Parts are grouped into two categories:

Full Parametric Equivalents: VBM211-75, VBM511-75, and VBM511-75-1502 maintain all critical electrical and mechanical parameters identical to the main part. Variations exist only in dielectric material composition, body finish, and mating cycle ratings, which do not affect functional interchangeability in standard 75 Ohm applications.

Conditional Equivalents: 112800 (Amphenol RF) and CONBNC002 (TE Connectivity Linx) share the same connector style, mounting type, and termination method but differ in impedance specification or other secondary parameters, requiring application-level verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

VBM211-75, VBM511-75, and VBM511-75-1502 are direct parametric equivalents to the VBM201-75 and are suitable for immediate substitution in 75 Ohm applications. All three parts maintain active product status and meet RoHS compliance requirements. VBM211-75 and VBM511-75-1502 both support 500 mating cycles, matching the main part specification. VBM511-75 operates at 100 mating cycles, which may be limiting in high-cycle applications. VBM211-75 uses polyoxymethylene (POM) dielectric material, while VBM511-75 and VBM511-75-1502 use polypropylene (PP), consistent with the main part. VBM511-75-1502 features tin body finish instead of nickel, which may affect corrosion resistance in specific environmental conditions.

112800 (Amphenol RF) maintains 75 Ohm impedance and all critical mounting and termination parameters. This part uses beryllium copper center contact material and PTFE dielectric, which may provide superior high-frequency performance characteristics. ROHS3 compliance and REACH Affected status require verification against project-specific regulatory requirements.

CONBNC002 (TE Connectivity Linx) operates at 50 Ohms impedance, which is incompatible with the 75 Ohm specification of the main part. This part is not suitable for direct substitution in applications requiring 75 Ohm characteristic impedance. Extended operating temperature range (-65°C ~ 165°C) may be beneficial for extreme environment applications, but impedance mismatch precludes use as a functional equivalent.

Frequently Asked Questions (FAQ)

Q: Can VBM511-75 replace VBM201-75 in all applications?

A: VBM511-75 is electrically and mechanically equivalent to VBM201-75 across all critical parameters. However, VBM511-75 is rated for 100 mating cycles compared to 500 cycles for VBM201-75. In applications requiring frequent connector mating and unmating, the reduced cycle rating may limit service life. Verify application duty cycle requirements before substitution.

Q: What is the difference between VBM211-75 and VBM511-75?

A: Both parts are parametric equivalents with identical electrical specifications and 500 mating cycle ratings. The primary difference is dielectric material: VBM211-75 uses polyoxymethylene (POM) while VBM511-75 uses polypropylene (PP). VBM211-75 specifies 0.2 dB insertion loss. Material selection may affect performance in specific frequency or temperature applications.

Q: Why is CONBNC002 listed as a substitute if it has 50 Ohm impedance?

A: CONBNC002 is included in the substitute list from the provided input data but operates at 50 Ohm impedance, which is incompatible with the 75 Ohm specification of VBM201-75. Direct substitution is not recommended for applications requiring 75 Ohm characteristic impedance. Use only if application impedance requirements can accommodate 50 Ohm operation.

Q: Are there packaging differences between substitute parts?

A: VBM201-75, VBM211-75, and VBM511-75 are supplied in bulk packaging. VBM511-75-1502, 112800, and CONBNC002 are supplied in bag packaging. Packaging format does not affect connector functionality but may impact inventory management and handling procedures.

Q: What compliance certifications should I verify before selecting a substitute?

A: All listed parts maintain active product status. VBM201-75, VBM511-75, and VBM511-75-1502 are RoHS Compliant. VBM211-75, 112800, and CONBNC002 are ROHS3 Compliant. 112800 carries REACH Affected status, requiring verification against project-specific regulatory requirements. CONBNC002 is REACH Unaffected. Confirm compliance requirements with your procurement and regulatory teams before final part selection.
