Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BV030-7085.0 is determined by the following critical parameters:

• Power rating: 10VA
• Core type: Laminated
• Primary voltage options: 115V and 230V dual configuration
• Secondary voltage configuration: Parallel 18V and series 36V dual winding
• Output current capacity: Parallel 554mA minimum, series 277mA minimum
• Mounting: Through-hole with PC pin termination
• Winding configuration: Dual primary and dual secondary

The substitute part 14A-10R-36 from Signal Transformer meets all these core electrical and mechanical requirements, enabling direct functional replacement in applications requiring this transformer specification.

Parameter Comparison

Engineering Selection Recommendations

The 14A-10R-36 from Signal Transformer qualifies as a direct functional substitute for the obsolete BV030-7085.0. Both components share identical electrical specifications for power rating, primary and secondary voltage configurations, winding arrangements, and output current capacity. The substitute part operates at active product status, ensuring ongoing availability and supply chain continuity.

Physical dimensions differ slightly: the 14A-10R-36 is smaller in footprint (47.60mm L x 39.70mm W versus 53.00mm L x 44.00mm W) but taller when seated (34.90mm versus 28.00mm). PCB layout verification is required to confirm mechanical fit within the target application.

The 14A-10R-36 provides specified isolation voltage of 4000Vrms, whereas the original part does not specify this parameter. Both components maintain REACH Unaffected and EAR99 export classification status. The substitute part carries RoHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the 14A-10R-36 directly replace the BV030-7085.0 in existing designs?

A: Yes, from an electrical standpoint. Both transformers provide identical power rating (10VA), primary voltage options (115V/230V), secondary voltage configuration (parallel 18V/series 36V), and output current capacity. Physical dimensions require verification for PCB fit.

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

A: The primary differences are physical dimensions and product status. The 14A-10R-36 is smaller in footprint but taller in height. The substitute is an active product with specified 4000Vrms isolation voltage and RoHS3 compliance, whereas the original is obsolete with unspecified isolation voltage.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain identical REACH and ECCN classifications. The 14A-10R-36 includes RoHS3 compliance certification, which may be advantageous for new designs or updated procurement requirements.

Q: What should be verified before implementing this substitute?

A: Confirm that the PCB layout accommodates the different physical dimensions, particularly the increased height (34.90mm versus 28.00mm). Verify that the 4000Vrms isolation specification of the substitute meets or exceeds application requirements.
