BV030-6941.0 Equivalent & Substitute Parts

Part Overview

The BV030-6941.0 is a laminated core power transformer manufactured by Pulse Electronics, rated at 4VA 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 classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BV030-6941.0 is based on the following critical parameters that must remain consistent or exceed the original specification:

Mandatory Matching Parameters:

• Laminated core construction type
• Dual primary winding configuration supporting 115V and 230V inputs
• Dual secondary winding configuration supporting parallel 12V and series 24V outputs
• Through-hole mounting with PC pin termination
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN classification EAR99

Allowable Variance Parameters:

• Power rating may exceed 4VA (higher capacity acceptable)
• Output current capacity may exceed specified maximums (higher current acceptable)
• Physical dimensions may differ provided through-hole mounting compatibility is maintained
• Product status may be active (preferred over obsolete)
• Additional certifications such as RoHS compliance are acceptable enhancements

The substitute part PL5.0-24-130B from Tamura meets all mandatory matching criteria while providing enhanced specifications in power rating (5VA) and output current capacity.

Engineering Selection Recommendations

The PL5.0-24-130B from Tamura is a qualified substitute for the obsolete BV030-6941.0. Selection rationale is based on the following engineering factors:

Product Status Advantage: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Electrical Compatibility: All primary and secondary voltage configurations are identical. Output current capacity exceeds the original specification in both parallel (420mA vs. 332mA) and series (210mA vs. 166mA) configurations, providing design margin for existing applications.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications. The substitute part carries RoHS compliance certification, meeting modern environmental and regulatory requirements.

Physical Integration: Both components utilize through-hole mounting with PC pin termination. Dimensional differences (41.28mm L x 36.37mm W x 35.60mm H for substitute versus 53.00mm L x 44.00mm W x 19.00mm H for original) require PCB layout verification to confirm mechanical fit within existing designs.

Functional Equivalence: Dual primary and secondary winding configurations, laminated core construction, and unlimited moisture sensitivity rating ensure functional equivalence for applications originally designed around the BV030-6941.0.

Frequently Asked Questions (FAQ)

Q: Can the PL5.0-24-130B directly replace the BV030-6941.0 in existing designs?

A: Electrical substitution is valid based on matching voltage configurations and exceeding current capacity. Physical substitution requires verification of PCB layout compatibility due to dimensional differences. The substitute part is taller (35.60mm vs. 19.00mm) and smaller in footprint area.

Q: What are the key parameters that define substitution eligibility?

A: Laminated core type, dual primary winding supporting 115V/230V input, dual secondary winding supporting 12V parallel and 24V series output, through-hole mounting, PC pin termination, and MSL 1 rating are mandatory matching criteria. Power rating and output current may exceed original specifications.

Q: Why is the substitute part rated at 5VA instead of 4VA?

A: The 5VA rating represents increased power handling capacity. This exceeds the original 4VA specification and is acceptable for substitution purposes, as it provides additional design margin without reducing functionality.

Q: Are there compliance differences between the original and substitute parts?

A: Both parts share identical ECCN and HTSUS classifications. The substitute part includes RoHS compliance certification, which the original part does not specify. This represents an enhancement for regulatory compliance in modern applications.

Q: What should be verified before implementing the PL5.0-24-130B as a substitute?

A: Verify PCB layout compatibility with the substitute part's dimensions (41.28mm L x 36.37mm W x 35.60mm H). Confirm that the increased height does not create mechanical interference with adjacent components or enclosure constraints. Electrical functionality is directly compatible based on matching winding configurations and voltage ratings.
