LP-30-200 Equivalent & Substitute Parts

Part Overview

The LP-30-200 is a semi-toroidal power transformer rated at 6VA, manufactured by Signal Transformer. It features dual primary and secondary windings with selectable voltage configurations (115V or 230V primary input; 15V parallel or 30V series secondary output). The device is designed for through-hole mounting with PC pin termination and is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange.

Key Parameters

Substitute Part Grouping Explanation

The FP30-200 manufactured by Triad Magnetics qualifies as a direct substitute based on the following critical parameters:

• Identical power rating: 6VA
• Matching primary voltage options: 115V, 230V
• Matching secondary voltage configurations: 15V parallel, 30V series
• Identical output current specifications: 400mA parallel, 200mA series
• Matching winding configuration: Dual primary, dual secondary
• Compatible mounting and termination: Through hole with PC pin termination
• Equivalent compliance certifications: ROHS3 compliant, REACH unaffected, EAR99 classification

The primary distinction between the main part and substitute is the core construction type (semi-toroidal versus laminated core) and isolation voltage rating (1500Vrms versus 2000Vrms). Both devices meet the specified electrical and mechanical requirements for direct interchange in applications where these parameters are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the LP-30-200 and FP30-200 are active production components with equivalent regulatory compliance. Selection between these parts should be based on the following factors:

The FP30-200 provides a higher isolation voltage rating (2000Vrms versus 1500Vrms), which may be advantageous in applications requiring enhanced electrical isolation. The laminated core construction of the FP30-200 differs from the semi-toroidal design of the LP-30-200, which may affect electromagnetic performance characteristics not specified in the provided parameters.

Physical dimensions are nearly identical, with the FP30-200 having a maximum seated height of 22.22mm compared to 21.60mm for the LP-30-200. This 0.62mm difference should be evaluated against PCB layout constraints.

Both parts maintain identical electrical specifications for voltage, current, and power delivery, ensuring functional compatibility in applications designed for either component.

Frequently Asked Questions (FAQ)

Q: Can the FP30-200 be used as a direct replacement for the LP-30-200?

A: Yes. Both transformers provide identical electrical specifications: 6VA power rating, dual 115V/230V primary inputs, dual 15V parallel or 30V series secondary outputs, and 400mA/200mA maximum output currents. Through-hole mounting and PC pin termination are identical. Physical dimensions are within 0.13mm for length and width, with height differing by 0.62mm.

Q: What is the difference between semi-toroidal and laminated core construction?

A: The LP-30-200 uses semi-toroidal core construction, while the FP30-200 uses laminated core construction. Both are transformer core types; the specific electromagnetic performance differences are not provided in the available specifications.

Q: Does the higher isolation voltage of the FP30-200 affect compatibility?

A: The FP30-200 provides 2000Vrms isolation compared to 1500Vrms for the LP-30-200. This represents an enhanced isolation specification and does not reduce compatibility. Applications designed for 1500Vrms isolation will operate with the FP30-200.

Q: Are there packaging differences between these parts?

A: The LP-30-200 is supplied in bulk packaging, while the FP30-200 is supplied in box packaging. Both are through-hole components with identical termination styles.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the LP-30-200 and FP30-200 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
