F-379P Equivalent & Substitute Parts Reference

Part Overview

The F-379P is a laminated core power transformer manufactured by Triad Magnetics, rated at 24VA with dual primary and dual secondary windings. This through-hole mounted component is designed for applications requiring 115V or 230V primary input with configurable secondary output of 60V parallel or 120V series. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Equivalent parts are identified when identical electrical specifications and mechanical compatibility are required for design flexibility, supply chain continuity, or inventory optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the F-379P is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Identical power rating: 24VA
Matching primary voltage inputs: 115V and 230V
Matching secondary voltage outputs: Parallel 60V and Series 120V
Matching secondary current capacity: Parallel 400mA and Series 200mA
Laminated core construction

Mechanical Equivalence Requirements:

Through-hole mounting configuration
PC pin termination style
Physical dimensions within tolerance for PCB mounting

Compliance Requirements:

RoHS3 compliance status
REACH unaffected status

The Hammond Manufacturing 160H120 meets all electrical and mechanical equivalence criteria, enabling direct substitution in applications where the F-379P is specified.

Engineering Selection Recommendations

Both the F-379P and 160H120 are Active products with RoHS3 compliance and REACH unaffected status, confirming suitability for current production applications. The 160H120 provides enhanced isolation voltage (2000Vrms versus 1500Vrms), which represents an operational advantage in high-voltage isolation applications without compromising compatibility.

Physical dimensions are within manufacturing tolerance, with the 160H120 measuring 0.12mm longer and 0.12mm taller than the F-379P. These variations are negligible for through-hole PCB mounting applications and do not affect electrical performance or mechanical fit.

The secondary winding configuration difference (dual versus single with multiple taps) does not affect substitution eligibility, as both configurations deliver the required parallel 60V/400mA and series 120V/200mA outputs.

Selection between these parts should be based on availability, lead time, packaging requirements (Box versus Bulk), and supplier preference, as all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 160H120 directly replace the Triad F-379P in existing designs?

A: Yes. Both parts deliver identical electrical specifications (24VA, 115V/230V primary, 60V parallel/120V series secondary) and are mechanically compatible through-hole components with PC pin termination. Physical dimensions are within tolerance for PCB mounting.

Q: What is the significance of the secondary winding configuration difference?

A: The F-379P specifies dual secondary windings, while the 160H120 specifies single secondary with multiple taps. Both configurations deliver the required output voltages and currents. The functional output remains equivalent.

Q: Does the higher isolation voltage of the 160H120 affect compatibility?

A: No. The 160H120's 2000Vrms isolation exceeds the F-379P's 1500Vrms requirement. Higher isolation voltage does not compromise compatibility and provides additional safety margin in high-voltage applications.

Q: Are there packaging differences between these parts?

A: Yes. The F-379P is supplied in Box packaging, while the 160H120 is supplied in Bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both the F-379P and 160H120 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for production use.

Q: Are physical dimension differences significant for PCB layout?

A: No. The 160H120 measures 41.40mm L x 57.15mm W x 35.05mm H (max seated), compared to the F-379P at 41.28mm L x 57.15mm W x 34.93mm H (max seated). These differences of 0.12mm are within standard PCB mounting tolerances and do not require design modification.
