F120-050 Equivalent & Substitute Parts Reference

Part Overview

The F120-050 is a laminated core power transformer manufactured by Triad Magnetics, rated at 6VA with a primary voltage of 115V and dual secondary windings configured for parallel (60V, 100mA) or series (120V, 50mA) operation. This through-hole mounted component is designed for Class 2/3 applications and is part of the Split Pack™ series. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Equivalent substitute parts are identified when identical electrical specifications, mechanical dimensions, mounting characteristics, and isolation ratings are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F120-050 are qualified based on strict equivalence across the following critical parameters:

Electrical Specifications: Primary voltage (115V), secondary voltage configuration (parallel 60V/series 120V), output current ratings (parallel 100mA/series 50mA), power rating (6VA), isolation voltage (2500Vrms), and winding configuration (single primary, dual secondary, no center tap).

Mechanical Specifications: Through-hole mounting type, PC pin termination style, physical dimensions (41.28mm L x 33.32mm W x 33.32mm H seated), and weight (0.44 lb).

Compliance & Status: Active product status, ROHS3 compliance, REACH unaffected designation, and laminated core construction.

Substitution is valid only when all parameters listed above are identical between the main part and the candidate substitute. No parameter deviation is permitted.

Parameter Comparison

Engineering Selection Recommendations

The 164F120 manufactured by Hammond Manufacturing is a direct electrical and mechanical equivalent to the F120-050. All critical performance parameters, dimensional specifications, isolation ratings, and compliance certifications are identical. Both parts are active products with ROHS3 compliance and REACH unaffected status.

The only difference between these parts is packaging format: the F120-050 is supplied in box packaging, while the 164F120 is supplied in bulk packaging. This distinction affects inventory management and handling procedures but does not impact electrical performance or mechanical compatibility in circuit applications.

Selection between these equivalent parts should be based on packaging requirements, supplier availability, lead time, and cost considerations. Both parts are suitable for direct substitution in through-hole PCB applications requiring 6VA laminated core transformers with dual secondary windings and 2500Vrms isolation.

Frequently Asked Questions (FAQ)

Q: Can the 164F120 be used as a direct replacement for the F120-050 in existing designs?

A: Yes. The 164F120 is electrically and mechanically equivalent to the F120-050. All voltage ratings, current ratings, power specifications, mounting characteristics, and isolation ratings are identical. Direct substitution is valid for through-hole PCB applications.

Q: What is the difference between box and bulk packaging for these transformers?

A: Box packaging (F120-050) typically includes individual component packaging suitable for smaller quantity orders and component traceability. Bulk packaging (164F120) is used for higher volume orders and reduces per-unit packaging material. The transformer itself is identical in both cases.

Q: Are both parts suitable for Class 2/3 applications?

A: The F120-050 is specified for Class 2/3 applications as part of the Split Pack™ series. The 164F120 specifications provided do not explicitly state Class 2/3 designation. Verify Class 2/3 compliance with Hammond Manufacturing documentation before substitution in applications where this classification is required.

Q: What is the isolation voltage rating, and why is it important?

A: Both parts provide 2500Vrms isolation between primary and secondary windings. This rating determines the maximum voltage differential that can be safely applied across the transformer windings and is critical for safety in applications involving mains voltage (115V primary) isolation from secondary circuits.

Q: Can these transformers be configured for different voltage outputs?

A: Yes. Both the F120-050 and 164F120 feature dual secondary windings that can be connected in parallel (60V, 100mA output) or series (120V, 50mA output). The configuration is determined by how the secondary windings are connected in the circuit.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory or compliance differences exist between the F120-050 and 164F120 based on provided specifications.
