F48-023 Equivalent & Substitute Parts Reference

Part Overview

The F48-023 is a laminated core power transformer manufactured by Triad Magnetics, rated at 1.1VA with dual secondary windings. This through-hole mounted component operates with a 115V primary voltage and provides configurable secondary outputs of 24V (parallel) or 48V (series). The part is actively produced and maintains ROHS3 compliance with 2500Vrms isolation rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F48-023 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical primary voltage: 115V
• Identical secondary voltage configuration: Parallel 24V and Series 48V
• Identical maximum output current: Parallel 46mA, Series 23mA
• Identical power rating: 1.1VA
• Identical isolation voltage: 2500Vrms
• Identical winding configuration: Single primary, dual secondary, no center tap

Mechanical Equivalence Requirements:

• Identical mounting type: Through Hole
• Identical termination style: PC Pin
• Compatible core type: Laminated

Compliance Requirements:

• ROHS3 compliance maintained
• REACH unaffected status maintained
• Identical ECCN and HTSUS classifications

The Hammond Manufacturing 164D48 meets all electrical and compliance criteria. Mechanical dimensions show minor variations in height (33.32mm vs. 23.80mm seated height) and width (28.56mm vs. 28.58mm), which remain within acceptable tolerance for through-hole PCB mounting applications.

Engineering Selection Recommendations

F48-023 (Triad Magnetics) - Primary Selection

The F48-023 is the specified component with active production status and established supply availability (1090 pcs in stock). This part maintains all required electrical specifications and compliance certifications. The seated height of 23.80mm provides a compact profile suitable for standard PCB layouts.

164D48 (Hammond Manufacturing) - Qualified Substitute

The 164D48 provides complete electrical equivalence with identical power delivery, voltage configurations, and isolation characteristics. Both parts maintain ROHS3 and REACH compliance. The 164D48 features increased seated height (33.32mm), which requires verification of available PCB clearance in the target application. Width tolerance (28.56mm vs. 28.58mm) is negligible for through-hole mounting. The 164D48 maintains active production status with higher inventory availability (1243 pcs in stock).

Selection Criteria:

• Use F48-023 when PCB height constraints require the lower profile (23.80mm seated height)
• Use 164D48 when inventory availability or supply chain timing favors Hammond Manufacturing sourcing
• Both parts are electrically interchangeable for applications requiring 1.1VA power transformation with dual secondary winding configuration

Frequently Asked Questions (FAQ)

Q: Can the 164D48 be used as a direct replacement for the F48-023?

A: The 164D48 provides complete electrical equivalence in power rating, voltage outputs, current capacity, and isolation specifications. The primary difference is seated height (33.32mm vs. 23.80mm). Substitution is valid provided PCB layout accommodates the increased height and no mechanical constraints exist in the target assembly.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires equivalence in: primary voltage (115V), secondary voltage configuration (24V parallel / 48V series), output current ratings (46mA parallel / 23mA series), power rating (1.1VA), isolation voltage (2500Vrms), core type (laminated), mounting method (through-hole), termination style (PC pin), and winding configuration (dual secondary, no center tap). Compliance certifications (ROHS3, REACH) must also be maintained.

Q: Are there any packaging differences between these parts?

A: The F48-023 is supplied in Box packaging, while the 164D48 is supplied in Bulk packaging. This distinction affects handling and storage procedures but does not impact electrical performance or mechanical compatibility.

Q: What is the significance of the height difference between these transformers?

A: The F48-023 has a maximum seated height of 23.80mm, while the 164D48 measures 33.32mm. This 9.52mm difference is relevant only for applications with vertical space constraints on the PCB. For standard through-hole mounting applications without height restrictions, this difference is not a limiting factor.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the F48-023 and 164D48 are ROHS3 compliant and REACH unaffected. Both share identical ECCN (EAR99) and HTSUS (8504.31.4035) classifications, ensuring equivalent regulatory status for procurement and export purposes.

Q: What is the weight difference between these parts?

A: Both parts weigh 0.17 lb (77.11 g), indicating equivalent core material and construction mass despite the height variation.
