BV030-7073.0 Equivalent & Substitute Parts

Part Overview

The BV030-7073.0 is a 10VA laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting with dual primary and secondary windings. This component supports dual voltage configurations (115V/230V primary, 6V/12V secondary) and is classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The IF-10-12 from Signal Transformer qualifies as a functional substitute based on the following critical parameters:

• Power Rating Match: Both components are rated at 10VA
• Primary Voltage Compatibility: Both support 115V and 230V primary inputs
• Secondary Voltage Equivalence: Both provide parallel 6V and series 12V secondary outputs
• Secondary Current Compatibility: Output currents are within acceptable tolerance (1.67A parallel / 835mA series vs. 1.666A / 833mA)
• Winding Configuration: Both feature dual primary and dual secondary windings
• Mounting and Termination: Both use through-hole mounting with PC pin termination

The primary difference is core construction: BV030-7073.0 uses laminated core technology, while IF-10-12 employs semi-toroidal construction. This difference does not preclude functional substitution when electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The IF-10-12 is suitable for applications currently using BV030-7073.0 where the following conditions are met:

• Electrical specifications (voltage, current, power) are the primary selection criteria and are met by the substitute
• PCB layout accommodates the dimensional differences: IF-10-12 measures 67.60mm L × 57.00mm W × 22.60mm H (seated), compared to BV030-7073.0 at 53.00mm L × 44.00mm W × 28.00mm H (seated)
• The active product status of IF-10-12 ensures ongoing availability and supply chain continuity
• ROHS3 compliance of IF-10-12 aligns with current regulatory requirements
• The specified 4000Vrms isolation rating of IF-10-12 meets or exceeds typical application requirements

Frequently Asked Questions (FAQ)

Q: Can IF-10-12 directly replace BV030-7073.0 in existing designs?

A: Electrical compatibility is confirmed across all critical parameters. Physical layout verification is required due to dimensional differences. Mounting hole patterns and lead spacing must be validated against PCB design.

Q: What are the key differences between these transformers?

A: The primary differences are core construction (laminated vs. semi-toroidal), physical dimensions, weight, and product status. Electrical performance parameters are equivalent within specified tolerances.

Q: Why is BV030-7073.0 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. IF-10-12 provides functional equivalence with active manufacturing status.

Q: Are there compliance differences between these parts?

A: IF-10-12 carries ROHS3 compliance certification and specifies 4000Vrms isolation. BV030-7073.0 specifications do not include these details. Both share identical REACH and ECCN classifications.

Q: What should be verified before substitution?

A: Confirm PCB layout compatibility with the larger footprint of IF-10-12, verify mounting hole alignment, and validate that the semi-toroidal core construction meets electromagnetic interference requirements for the application.
