BV030-7079.0 Equivalent & Substitute Parts

Part Overview

The BV030-7079.0 is a laminated core power transformer manufactured by Pulse Electronics, rated at 10VA with dual primary and secondary windings. This through-hole mounted component is designed for applications requiring 115V or 230V primary input with configurable secondary output of 12V (parallel) or 24V (series). The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The FS28-420 manufactured by Triad Magnetics qualifies as a substitute for the BV030-7079.0 based on the following critical parameters:

Matching Electrical Characteristics:

• Dual primary winding configuration supporting 115V and 230V input
• Dual secondary winding configuration enabling parallel and series output modes
• Primary voltage range: 115V, 230V (identical)
• Secondary voltage parallel output: 14V (compared to 12V on original)
• Secondary voltage series output: 28V (compared to 24V on original)
• Output current capability in parallel mode: 840mA (compared to 832mA on original)
• Output current capability in series mode: 420mA (compared to 416mA on original)

Matching Mechanical & Interface Characteristics:

• Through-hole mounting type (identical)
• PC pin termination style (identical)
• Laminated core construction (identical)
• No center tap configuration (identical)

Compliance & Regulatory Alignment:

• REACH Unaffected status (identical)
• ECCN EAR99 classification (identical)
• HTSUS code 8504.31.4035 (identical)

The FS28-420 provides marginally higher power capacity (12VA vs. 10VA) and improved secondary voltage/current specifications, making it suitable for applications where the original BV030-7079.0 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The FS28-420 is the designated substitute for the obsolete BV030-7079.0. Selection of this substitute is supported by:

Product Status Consideration: The BV030-7079.0 is classified as obsolete, while the FS28-420 maintains active product status with confirmed inventory availability (1464 units in stock). This ensures long-term supply chain viability.

Compliance Alignment: Both components share identical REACH and ECCN classifications, ensuring regulatory compliance continuity across applications.

Electrical Performance: The FS28-420 delivers equivalent or superior electrical performance across all critical parameters. Secondary voltage outputs differ by 2V in parallel mode (14V vs. 12V) and 4V in series mode (28V vs. 24V), with output current capabilities within 1% of the original specification. These marginal increases in voltage and current capacity are within acceptable engineering tolerances for most applications.

Mechanical Compatibility: Both components employ identical mounting (through-hole) and termination (PC pin) methodologies. Physical dimensions differ slightly, with the FS28-420 being more compact in length and width but taller when seated. PCB layout verification is required to confirm clearance compatibility.

Certification Status: The FS28-420 carries RoHS3 compliance certification, providing enhanced environmental compliance compared to the original component.

Frequently Asked Questions (FAQ)

Q: Can the FS28-420 directly replace the BV030-7079.0 without circuit modifications?

A: The FS28-420 is electrically compatible for most applications due to matching primary voltage inputs and dual winding configurations. However, the secondary voltage outputs are higher (14V parallel vs. 12V, and 28V series vs. 24V). Applications with strict voltage regulation requirements or narrow input tolerances may require circuit adjustment or voltage regulation components. PCB layout verification is mandatory due to dimensional differences.

Q: What are the key dimensional differences between these transformers?

A: The BV030-7079.0 measures 53.00mm (L) x 44.00mm (W) x 28.00mm (H seated). The FS28-420 measures 47.63mm (L) x 39.67mm (W) x 36.50mm (H seated). The substitute is more compact horizontally but extends 8.5mm higher. Verify PCB footprint and vertical clearance before implementation.

Q: Are there any compliance or certification differences?

A: Both components are REACH Unaffected and classified as EAR99. The FS28-420 additionally carries RoHS3 compliance certification, which the original part does not specify. This represents an improvement in environmental compliance standards.

Q: What is the power capacity difference, and does it matter?

A: The FS28-420 is rated at 12VA compared to the 10VA rating of the BV030-7079.0. This 20% increase in power capacity provides additional design margin and does not create compatibility issues for applications originally designed for the 10VA transformer.

Q: How do the output current specifications compare?

A: In parallel mode, the FS28-420 provides 840mA versus 832mA on the original (0.96% difference). In series mode, the FS28-420 provides 420mA versus 416mA on the original (1% difference). These differences are negligible for most applications.

Q: Is the FS28-420 available in the same packaging format?

A: The BV030-7079.0 packaging format is not specified in the original documentation. The FS28-420 is supplied in box packaging. Confirm packaging requirements for your procurement and assembly processes.
