FS120-160 Laminated Power Transformer Equivalent & Substitute Parts

Part Overview

The FS120-160 is a 20VA laminated core power transformer manufactured by Triad Magnetics, designed for through-hole mounting applications. This transformer features dual primary and secondary windings with selectable voltage configurations (115V or 230V primary input; 60V parallel or 120V series secondary output). The part is currently in active production status with ROHS3 compliance and 2500Vrms isolation rating.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent performance specifications across different manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the FS120-160 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating: 20VA
• Matching primary voltage options: 115V and 230V
• Matching secondary voltage configurations: 60V parallel and 120V series
• Matching output current specifications: 320mA parallel, 160mA series
• Equivalent isolation voltage: 2500Vrms minimum
• Dual primary and dual secondary winding configuration

Mechanical Equivalence Requirements:

• Through-hole mounting type
• PC pin termination style
• Laminated core construction
• Compatible physical dimensions and height envelope
• Equivalent weight classification

Compliance Requirements:

• ROHS3 compliance status
• REACH unaffected classification
• EAR99 ECCN rating

The Hammond Manufacturing 162H120 meets all electrical, mechanical, and compliance criteria for direct substitution with the FS120-160.

Parameter Comparison

Engineering Selection Recommendations

FS120-160 (Triad Magnetics):

• Primary selection for applications requiring Split Pack™ series configuration
• Active production status with 1048 units in current inventory
• Box packaging suitable for controlled component environments
• ROHS3 and REACH compliance confirmed

162H120 (Hammond Manufacturing):

• Direct electrical and mechanical equivalent for FS120-160
• Active production status with 906 units in current inventory
• Bulk packaging configuration
• ROHS3 and REACH compliance confirmed
• MSL rating of 1 (Unlimited) provides extended storage capability

Both parts satisfy identical electrical performance requirements, mechanical mounting specifications, and regulatory compliance standards. Selection between these two substitutes is determined by packaging requirements, inventory availability, and supply chain logistics rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 162H120 be used as a direct replacement for the FS120-160 in existing designs?

A: Yes. The 162H120 is electrically and mechanically equivalent to the FS120-160 across all specified parameters including power rating, voltage configurations, output current ratings, isolation voltage, mounting type, and termination style. Both parts feature identical laminated core construction with dual primary and secondary windings.

Q: What are the key differences between these two transformer models?

A: The primary differences are manufacturer (Triad Magnetics versus Hammond Manufacturing), packaging format (Box versus Bulk), and MSL rating (Not Applicable versus 1 Unlimited). All electrical specifications, mechanical dimensions, and compliance certifications are equivalent.

Q: Are the physical dimensions identical between FS120-160 and 162H120?

A: Dimensions are equivalent. Both transformers measure 57.15mm length by 47.63mm width. The seated height differs by 0.02mm (FS120-160: 36.50mm maximum; 162H120: 36.52mm maximum), which is within standard manufacturing tolerance and does not affect PCB layout or mounting compatibility.

Q: What does the MSL rating difference mean for component storage?

A: The FS120-160 has MSL Not Applicable, while the 162H120 has MSL 1 (Unlimited). This indicates the 162H120 has no moisture sensitivity restrictions during storage and handling, providing greater flexibility in inventory management and extended shelf life without special environmental controls.

Q: Do both transformers meet current regulatory requirements?

A: Yes. Both the FS120-160 and 162H120 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both parts are in active production status.

Q: Can these transformers be used interchangeably in high-voltage isolation applications?

A: Yes. Both transformers provide 2500Vrms isolation voltage rating, meeting identical isolation specifications for safety-critical and high-voltage isolation requirements.

Q: What output current configurations are available with these transformers?

A: Both transformers support dual winding configurations allowing 320mA maximum output current in parallel connection or 160mA maximum output current in series connection, with corresponding secondary voltage outputs of 60V parallel or 120V series.
