LP12-200B24 Equivalent & Substitute Parts

Part Overview

The LP12-200B24 is a semi-toroidal power transformer manufactured by Pulse Electronics, rated at 2VA with dual primary and secondary windings. This through-hole component is designed for applications requiring low-profile plug-in transformer solutions with configurable output voltage (parallel 6.3V or series 12.6V) and corresponding current ratings. The part is active in production status with full RoHS compliance and 1500Vrms isolation rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range.

Key Parameters

Substitute Part Grouping Explanation

The LP-12-200 manufactured by Signal Transformer qualifies as a direct substitute for the LP12-200B24 based on the following critical parameters:

• Electrical Equivalence: Identical secondary voltage configuration (parallel 6.3V, series 12.6V) and output current ratings (parallel 400mA, series 200mA)
• Power Rating: Both rated at 2VA maximum power
• Winding Configuration: Dual primary and dual secondary windings with no center tap
• Isolation Voltage: Both maintain 1500Vrms isolation rating
• Mechanical Compatibility: Through-hole mounting with PC pin termination; physical dimensions within acceptable tolerance (length 47.50mm vs 47.63mm, width 39.60mm vs 39.67mm, height 16.50mm vs 16.51mm)
• Compliance: Both RoHS compliant and REACH unaffected with matching HTSUS classification

Parameter Comparison

Engineering Selection Recommendations

The LP-12-200 from Signal Transformer is a qualified substitute for the LP12-200B24. Both components maintain active product status and meet identical electrical and mechanical specifications. The LP-12-200 carries ROHS3 compliance, which supersedes the RoHS compliance designation of the original part. Physical dimensions are equivalent within standard manufacturing tolerances. Selection between these parts may be based on availability, lead time, packaging requirements (bulk vs. standard), or supply chain preferences, as all critical functional parameters are matched.

Frequently Asked Questions (FAQ)

Q: What determines if the LP-12-200 can replace the LP12-200B24?

A: Substitution is valid when secondary voltage output (parallel 6.3V, series 12.6V), maximum output current (parallel 400mA, series 200mA), power rating (2VA), winding configuration (dual primary, dual secondary), isolation voltage (1500Vrms), and mechanical form factor (through-hole, PC pin termination) are identical. The LP-12-200 meets all these criteria.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard manufacturing tolerance: length differs by 0.13mm (47.63mm vs 47.50mm), width by 0.07mm (39.67mm vs 39.60mm), and height by 0.01mm (16.51mm vs 16.50mm). These differences do not affect PCB layout or mechanical fit for standard through-hole applications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current iteration of the standard. Both parts meet the same hazardous substance restrictions and are suitable for equivalent applications.

Q: Can the LP-12-200 be used in the same circuit without modification?

A: Yes. Electrical specifications, isolation voltage, winding configuration, and termination style are identical. The component can be substituted directly in applications designed for the LP12-200B24.

Q: What packaging options are available?

A: The LP12-200B24 is supplied in standard packaging, while the LP-12-200 is available in bulk packaging. Packaging selection depends on order quantity and inventory management requirements.
