FS48-050 Equivalent & Substitute Parts Reference

Part Overview

The FS48-050 is a laminated core power transformer manufactured by Triad Magnetics, rated at 2.5VA with dual primary and secondary windings. This through-hole mounted component operates at 115V or 230V primary voltage with configurable secondary output of 24V parallel or 48V series. The transformer is designed for applications requiring isolated power conversion in compact form factors and maintains active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter set, enabling component selection flexibility for procurement, inventory management, or design revision scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FS48-050 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Primary voltage configuration: 115V and 230V dual input
• Secondary voltage output: 24V parallel and 48V series capability
• Output current capacity: 100mA parallel, 50mA series minimum
• Isolation voltage: 2500Vrms minimum
• Winding configuration: Dual primary and dual secondary

Mechanical Compatibility Requirements:

• Mounting type: Through hole only
• Termination style: PC pin configuration
• Physical footprint: 34.93mm L x 28.58mm W maximum
• Height seated: 30.15mm maximum
• Core type: Laminated construction

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status
• Active product status

The Hammond Manufacturing 162E48 meets all specified electrical and mechanical parameters with a minor power rating variance (2.4VA versus 2.5VA), which remains within acceptable substitution tolerance for this transformer category.

Parameter Comparison

Engineering Selection Recommendations

FS48-050 (Triad Magnetics): Primary selection for applications where the 2.5VA power rating is specified. Active product status with established supply chain. ROHS3 compliant and REACH unaffected. Packaging in box format suitable for controlled inventory environments.

162E48 (Hammond Manufacturing): Functionally equivalent substitute with 2.4VA power rating. Active product status with higher current inventory availability (814 pcs versus 691 pcs). ROHS3 compliant and REACH unaffected. Bulk packaging format. Suitable for applications where the 2.4VA rating meets load requirements and component procurement flexibility is prioritized.

Both parts satisfy identical electrical specifications for primary voltage, secondary voltage configuration, output current capacity, isolation voltage, and winding architecture. Mechanical compatibility is confirmed across mounting type, termination style, physical dimensions, and height specifications. Regulatory compliance is equivalent for both RoHS3 and REACH status.

Frequently Asked Questions (FAQ)

Q: Can the 162E48 directly replace the FS48-050 in existing designs?

A: Yes. The 162E48 maintains identical electrical specifications for primary voltage (115V/230V), secondary voltage output (24V parallel, 48V series), output current capacity (100mA parallel, 50mA series), isolation voltage (2500Vrms), and winding configuration (dual primary, dual secondary). Mechanical compatibility is confirmed through identical mounting type (through hole), termination style (PC pin), physical dimensions (34.93mm L x 28.58mm W), and height (30.15mm maximum seated). The 2.4VA power rating of the 162E48 versus 2.5VA of the FS48-050 represents a minor variance within acceptable substitution tolerance for this transformer category.

Q: What is the significance of the power rating difference between 2.5VA and 2.4VA?

A: Both transformers deliver identical output current specifications (100mA at 24V parallel, 50mA at 48V series). The power rating variance reflects manufacturing design differences while maintaining equivalent functional performance across specified load conditions. Selection between these parts should be based on application load requirements and component availability rather than the minor VA rating difference.

Q: Are packaging differences between box and bulk formats relevant to substitution?

A: Packaging format (box versus bulk) affects inventory management and component handling but does not impact electrical or mechanical compatibility. Selection between packaging formats depends on procurement quantity requirements, storage conditions, and supply chain logistics rather than functional substitution criteria.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the FS48-050 and 162E48 maintain ROHS3 compliance and REACH unaffected status. Both parts carry active product status, confirming ongoing manufacturer support and compliance maintenance.

Q: What parameters must remain identical for substitution to be valid?

A: Substitution validity requires identical specifications across primary voltage configuration, secondary voltage output, output current capacity, isolation voltage, core type (laminated), winding configuration (dual primary and secondary), mounting type (through hole), termination style (PC pin), and physical dimensions. Compliance status (RoHS3, REACH) must also be maintained.
