FS56-045 Equivalent & Substitute Parts

Part Overview

The FS56-045 is a laminated core power transformer manufactured by Triad Magnetics, rated at 2.5VA with dual primary and secondary windings. This through-hole mounted component operates at 115V or 230V primary voltage with selectable output configurations of 28V parallel or 56V series. The transformer is actively produced and maintains ROHS3 compliance with 2500Vrms isolation rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, procurement lead times, or inventory constraints. Substitutes must maintain identical or compatible voltage ratings, current output specifications, mounting configuration, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FS56-045 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Primary voltage options must include both 115V and 230V
• Secondary voltage outputs must provide both 28V parallel and 56V series configurations
• Maximum output current must support 90mA parallel and 45mA series operation
• Isolation voltage rating must equal or exceed 2500Vrms
• Power rating must be sufficient for 2.5VA operation

Mechanical Compatibility Requirements:

• Mounting type must be through-hole
• Termination style must be PC pin
• Physical footprint dimensions must match: 34.93mm L x 28.58mm W
• Maximum seated height must not exceed 30.15mm
• Core type must be laminated

Regulatory Compliance Requirements:

• ROHS3 compliance status must be maintained
• REACH unaffected status must be preserved

The substitute part 162E56 meets all electrical, mechanical, and regulatory criteria for direct substitution with the FS56-045.

Parameter Comparison

Engineering Selection Recommendations

The 162E56 manufactured by Hammond Manufacturing is a direct substitute for the FS56-045. Both components maintain active product status and full ROHS3 compliance. The 162E56 delivers identical electrical performance across all specified voltage and current parameters with matching mechanical footprint and through-hole PC pin termination.

The 162E56 operates at 2.4VA maximum power, which is 0.1VA lower than the FS56-045 specification of 2.5VA. This difference does not affect substitution eligibility, as the 162E56 maintains full output current capability at both parallel (90mA) and series (45mA) configurations. Both transformers provide equivalent 2500Vrms isolation voltage and identical winding configurations.

Component selection between FS56-045 and 162E56 is determined by availability, procurement lead time, and inventory status. Both parts satisfy identical application requirements for laminated core power transformation in through-hole mounted circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can the 162E56 be used as a direct replacement for the FS56-045 in existing circuit board designs?

A: Yes. The 162E56 provides identical primary and secondary voltage configurations, matching output current ratings, and equivalent physical dimensions with PC pin through-hole termination. No circuit board layout modifications are required.

Q: What is the significance of the 0.1VA power rating difference between the FS56-045 (2.5VA) and 162E56 (2.4VA)?

A: The power rating difference does not impact substitution compatibility. Both transformers deliver identical maximum output current specifications of 90mA at 28V parallel and 45mA at 56V series. The 162E56 is suitable for applications designed for the FS56-045.

Q: Are both transformers compliant with current environmental regulations?

A: Yes. Both the FS56-045 and 162E56 maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Do the transformers require different mounting procedures?

A: No. Both components use identical through-hole PC pin termination and share matching physical dimensions of 34.93mm length, 28.58mm width, and 30.15mm maximum seated height. Standard through-hole soldering procedures apply to both parts.

Q: What isolation voltage rating do these transformers provide?

A: Both the FS56-045 and 162E56 provide 2500Vrms isolation voltage, meeting high-voltage isolation requirements for safety-critical applications.

Q: Can these transformers be configured for both 115V and 230V primary input?

A: Yes. Both transformers feature dual primary windings that support selection of either 115V or 230V input voltage. Secondary output can be configured as 28V parallel or 56V series through dual secondary winding selection.
