FS20-1000 Equivalent & Substitute Parts Reference

Part Overview

The FS20-1000 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; 10V parallel or 20V series secondary output). The part is currently active in production with 839 units in stock inventory.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative packaging formats are required for specific manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FS20-1000 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical power rating (20VA)
• Matching primary voltage options (115V, 230V)
• Matching secondary voltage outputs (10V parallel, 20V series)
• Matching output current specifications (2A parallel, 1A series)
• Identical isolation voltage (2500Vrms)
• Identical core type (Laminated)
• Matching winding configuration (Dual primary, Dual secondary)

Mechanical Equivalence Requirements:

• Identical mounting type (Through Hole)
• Identical termination style (PC Pin)
• Compatible physical dimensions (57.15mm L × 47.63mm W)
• Height variation tolerance: ±0.02mm maximum

Compliance Requirements:

• ROHS3 Compliant status
• REACH Unaffected status

The Hammond Manufacturing 162H20 meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the FS20-1000.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The FS20-1000 (Triad Magnetics, Split Pack™ series) is the specified component for applications requiring the original design validation and manufacturing documentation. This part maintains active production status with established inventory levels (839 units in stock).

Substitute Part Selection: The 162H20 (Hammond Manufacturing, 162 series) is electrically and mechanically equivalent to the FS20-1000 and qualifies for direct substitution in through-hole PCB applications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing.

Packaging Consideration: The primary difference between these parts is packaging format. The FS20-1000 is supplied in box packaging, while the 162H20 is supplied in bulk packaging. Bulk packaging may be advantageous for high-volume manufacturing environments where individual component packaging is not required.

Compliance Verification: Both parts satisfy identical compliance requirements (ROHS3, REACH Unaffected, EAR99 ECCN classification). No additional compliance verification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the 162H20 be used as a direct replacement for the FS20-1000 in existing designs?

A: Yes. The 162H20 meets all electrical and mechanical specifications of the FS20-1000. Both parts feature identical power ratings (20VA), primary voltage options (115V/230V), secondary voltage configurations (10V parallel/20V series), output current ratings (2A parallel/1A series), core type (laminated), winding configuration (dual primary/dual secondary), mounting type (through-hole), termination style (PC pin), isolation voltage (2500Vrms), and physical dimensions (57.15mm × 47.63mm). Height variation is within acceptable tolerance (36.50mm vs. 36.52mm).

Q: What is the difference between the FS20-1000 and 162H20?

A: The primary differences are manufacturer (Triad Magnetics vs. Hammond Manufacturing), product series designation (Split Pack™ vs. 162), and packaging format (box vs. bulk). All electrical and mechanical parameters are equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both the FS20-1000 and 162H20 maintain identical compliance status: ROHS3 Compliant and REACH Unaffected. Both are classified under ECCN EAR99 and HTSUS 8504.31.4035.

Q: What does "PC Pin" termination mean?

A: PC Pin termination refers to printed circuit board pins designed for direct insertion into through-hole PCB mounting. Both the FS20-1000 and 162H20 use this termination style.

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

A: Yes. Both transformers feature dual primary and dual secondary windings. The primary can be configured for 115V or 230V input. The secondary can be configured for 10V output (parallel winding connection) or 20V output (series winding connection).

Q: What is the significance of the 2500Vrms isolation voltage rating?

A: The 2500Vrms isolation voltage specifies the maximum voltage that can be safely applied between the primary and secondary windings without electrical breakdown. This rating is identical for both the FS20-1000 and 162H20.

Q: Is bulk packaging suitable for my manufacturing process?

A: Bulk packaging is appropriate for high-volume manufacturing environments where components are processed through automated assembly systems. Individual component packaging is not required in these applications. The 162H20 bulk packaging format may reduce material handling costs in such environments.
