Equivalent & Substitute Parts for F120-160 Laminated Power Transformer

Part Overview

The F120-160 is a 20VA laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting applications. This transformer features a single primary winding at 115V and dual secondary windings capable of parallel (60V, 320mA) or series (120V, 160mA) configurations. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when electrical specifications, mechanical dimensions, and regulatory compliance align within acceptable tolerances for direct board-level replacement.

Electrical Equivalence Requirements:

• Identical primary voltage: 115V
• Identical secondary voltage configuration: Parallel 60V and Series 120V
• Identical maximum output current ratings: Parallel 320mA and Series 160mA
• Identical power rating: 20VA
• Identical isolation voltage: 2500Vrms
• Identical winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Requirements:

• Identical mounting type: Through Hole
• Identical termination style: PC Pin
• Identical core type: Laminated
• Dimensional compatibility: Length 57.15mm, Width 47.63mm, Height ≤36.52mm

Regulatory Equivalence Requirements:

• RoHS3 Compliance
• REACH Unaffected status
• Identical HTSUS classification: 8504.31.4035

The Hammond Manufacturing 164H120 meets all substitution criteria and is classified as an equivalent substitute for the Triad Magnetics F120-160.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (F120-160): The F120-160 from Triad Magnetics is the specified component and remains the first choice for new designs and existing inventory replenishment. This part maintains Active product status with confirmed stock availability of 822 units. Full RoHS3 compliance and REACH unaffected designation confirm regulatory alignment for current and future applications.

Substitute Part Selection (164H120): The Hammond Manufacturing 164H120 is electrically and mechanically equivalent to the F120-160 and is suitable for direct substitution in through-hole PCB applications. All critical electrical parameters match exactly, including voltage ratings, current capacity, and isolation specifications. Dimensional compatibility is confirmed with a maximum height variance of 0.02mm (36.52mm vs. 36.50mm), which falls within standard PCB assembly tolerances. Both parts maintain identical RoHS3 and REACH compliance status. The 164H120 is available with 814 units in stock and carries Active product status.

Packaging Consideration: The F120-160 is supplied in Box packaging, while the 164H120 is supplied in Bulk packaging. This distinction affects inventory management and component handling but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 164H120 be used as a direct replacement for the Triad F120-160 on existing PCBs?

A: Yes. The 164H120 is electrically and mechanically equivalent. All voltage ratings, current capacities, winding configurations, and isolation specifications are identical. Through-hole mounting and PC pin termination are identical. The height difference of 0.02mm is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Are there any electrical performance differences between these two transformers?

A: No. Both transformers deliver identical electrical performance: 20VA power rating, 115V primary input, dual secondary windings with parallel (60V, 320mA) and series (120V, 160mA) configurations, and 2500Vrms isolation voltage.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the F120-160 and 164H120 are RoHS3 compliant and REACH unaffected. Both share the identical HTSUS classification code 8504.31.4035.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (F120-160) typically includes individual component packaging suitable for smaller orders or component traceability requirements. Bulk packaging (164H120) is used for larger quantity shipments and reduces per-unit packaging material. The transformer itself is identical in both cases.

Q: Can I mix F120-160 and 164H120 components in the same production run?

A: Yes. Since both transformers are electrically and mechanically equivalent with identical compliance certifications, they can be used interchangeably in the same design and production environment.

Q: What should I verify before substituting the 164H120 for the F120-160?

A: Confirm that your PCB design accommodates the maximum seated height of 36.52mm (the 164H120 specification). Verify that your supply chain and inventory management systems can accommodate the transition from Box to Bulk packaging if applicable. Both parts are otherwise direct equivalents with no additional verification required.
