Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FS56-220 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Power rating: 12VA
• Primary voltage configuration: Dual winding supporting 115V and 230V
• Secondary voltage outputs: Parallel 28V and Series 56V
• Maximum output currents: Parallel 440mA, Series 220mA
• Isolation voltage: 2500Vrms

Mechanical Specifications:

• Core type: Laminated
• Mounting method: Through Hole
• Termination style: PC Pin
• Footprint dimensions: 47.63mm L × 39.67mm W
• Height compatibility: Maximum seated height within acceptable tolerance

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status
• ECCN classification: EAR99
• HTSUS code: 8504.31.4035

The Hammond Manufacturing 162G56 meets all electrical and mechanical equivalence criteria and maintains identical regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (FS56-220): The FS56-220 is the original specification component, currently in active production with 718 units available. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications.

Substitute Part Selection (162G56): The Hammond Manufacturing 162G56 provides full electrical and mechanical equivalence to the FS56-220. Both parts maintain identical power ratings, voltage configurations, output currents, and isolation specifications. The 162G56 is also ROHS3 compliant and REACH unaffected. The seated height of the 162G56 (38.10mm maximum) exceeds the FS56-220 (36.50mm maximum) by 1.60mm; this difference must be evaluated against available PCB clearance in the target application. The 162G56 is available in bulk packaging with 984 units in stock, compared to the FS56-220 box packaging with 718 units.

Selection Criteria:

• Use FS56-220 when box packaging is required or when the 36.50mm height constraint is critical
• Use 162G56 when bulk packaging is acceptable and the additional 1.60mm height is accommodated by PCB layout
• Both parts are suitable for direct substitution in applications where the specified electrical and mechanical parameters are the design requirements

Frequently Asked Questions (FAQ)

Q: Can the 162G56 be used as a direct replacement for the FS56-220 in existing designs?

A: The 162G56 provides electrical equivalence across all specified parameters: 12VA power rating, dual primary windings (115V/230V), dual secondary windings (28V parallel/56V series), 440mA parallel output current, 220mA series output current, and 2500Vrms isolation. Mechanical compatibility is confirmed for footprint dimensions (47.63mm × 39.67mm). The seated height difference of 1.60mm (162G56 at 38.10mm vs. FS56-220 at 36.50mm) must be verified against PCB clearance requirements. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference in packaging between these two parts?

A: The FS56-220 is supplied in box packaging with 718 units in stock. The 162G56 is supplied in bulk packaging with 984 units in stock. Packaging selection depends on procurement requirements and inventory management practices.

Q: Are there any compliance or certification differences between the FS56-220 and 162G56?

A: Both parts share identical regulatory compliance status: ROHS3 compliant, REACH unaffected, EAR99 ECCN classification, and 8504.31.4035 HTSUS code. No compliance differences exist between the two parts.

Q: What parameters determine substitution eligibility for this transformer category?

A: Substitution eligibility is determined by equivalence in power rating (12VA), primary voltage configuration (115V/230V dual winding), secondary voltage outputs (28V parallel/56V series), output current specifications (440mA parallel/220mA series), core type (laminated), mounting method (through hole), termination style (PC pin), isolation voltage (2500Vrms), and regulatory compliance status (ROHS3/REACH). Mechanical dimensions must be compatible with PCB layout constraints.

Q: Is the 1.60mm height difference between the FS56-220 and 162G56 significant?

A: The height difference must be evaluated against specific PCB design constraints. The FS56-220 seated height is 36.50mm maximum; the 162G56 is 38.10mm maximum. Applications with tight vertical clearance requirements must use the FS56-220. Applications with adequate clearance can accommodate the 162G56 without functional impact.
