F48-050 Equivalent & Substitute Parts

Part Overview

The F48-050 is a laminated core power transformer manufactured by Triad Magnetics, rated at 2.5VA with dual secondary windings. This through-hole mounted component operates at 115V primary with configurable secondary outputs of 24V parallel or 48V series. The transformer is actively produced and maintains ROHS3 compliance with 2500Vrms isolation rating. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F48-050 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Primary voltage: 115V
• Secondary voltage configuration: Parallel 24V and Series 48V capability
• Output current capacity: Parallel 100mA minimum, Series 50mA minimum
• Isolation voltage: 2500Vrms minimum
• Winding configuration: Single primary, dual secondary, no center tap

Mechanical Compatibility Requirements:

• Mounting type: Through hole
• Termination style: PC pin
• Physical dimensions: Compatible footprint within specified length and width tolerances
• Height seated maximum: 30.15mm reference

Regulatory Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required

The Hammond Manufacturing 164E48 qualifies as a substitute based on matching all electrical parameters, mechanical mounting specifications, and regulatory certifications. The 2.4VA power rating of the 164E48 represents a 0.1VA reduction from the F48-050 specification; however, this remains within acceptable tolerance for applications designed for the F48-050 since the output current specifications (the limiting factor for load capacity) are identical.

Parameter Comparison

Engineering Selection Recommendations

F48-050 (Triad Magnetics): Select this part when Triad Magnetics sourcing is preferred or when the 2.5VA power specification is explicitly required by design documentation. The F48-050 maintains active production status with 1031 units in current inventory. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current applications.

164E48 (Hammond Manufacturing): Select this substitute when Hammond Manufacturing procurement channels are more favorable, when lead times require alternative sourcing, or when inventory availability of the F48-050 is constrained. The 164E48 delivers identical electrical performance through matching output current specifications and maintains equivalent mechanical compatibility. ROHS3 compliance and REACH unaffected status provide equivalent regulatory standing. The 2.4VA power rating differential does not impact functional compatibility for circuits designed around the 100mA parallel and 50mA series output current limits.

Both parts are actively produced and carry equivalent compliance certifications. Selection between these parts is driven by procurement logistics, inventory status, and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 164E48 be used as a direct replacement for the F48-050 in existing designs?

A: Yes. The 164E48 provides electrical equivalence across all critical parameters: identical primary voltage (115V), secondary voltage configurations (24V parallel, 48V series), output current ratings (100mA parallel, 50mA series), and isolation voltage (2500Vrms). Mechanical compatibility is confirmed through matching through-hole mounting, PC pin termination, and equivalent physical dimensions. Both parts carry ROHS3 compliance and REACH unaffected status.

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

A: The power rating difference reflects a 0.1VA variance between manufacturers' specifications. However, the limiting factor for load capacity in both transformers is the output current specification, which is identical: 100mA maximum in parallel configuration and 50mA maximum in series configuration. Applications designed for the F48-050 will operate within the 164E48 current limits and therefore experience no functional limitation.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are equivalent within engineering tolerance. Both parts measure 34.93mm length and approximately 28.57mm width. Height seated maximum values are 30.15mm (F48-050) and 30.18mm (164E48), representing a 0.03mm difference that does not impact PCB layout or mechanical clearance requirements.

Q: Do both parts support the same secondary voltage configurations?

A: Yes. Both the F48-050 and 164E48 feature dual secondary windings with identical configuration options: 24V parallel output at 100mA maximum or 48V series output at 50mA maximum. No center tap is present on either part.

Q: What packaging differences exist between these parts?

A: The F48-050 is supplied in box packaging, while the 164E48 is supplied in bulk packaging. This distinction affects inventory management and procurement quantities but does not impact component performance or compatibility.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts maintain ROHS3 compliance and REACH unaffected status, confirming equivalent regulatory standing for current applications. Isolation voltage specification of 2500Vrms is identical on both parts.
