Equivalent & Substitute Parts for F4-16 Laminated Power Transformer

Part Overview

The F4-16 is a laminated core power transformer manufactured by Triad Magnetics, rated at 6VA with a 115V primary and 16V secondary output. This chassis mount transformer is designed for applications requiring isolated AC power conversion with a maximum output current of 400mA. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F4-16 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Primary voltage (115V), secondary voltage (16V), maximum output current (400mA), and total power rating (6VA) must be identical. The presence of a center tap on the secondary winding is a required feature for substitution.

Core and Winding Configuration: The transformer must utilize a laminated core construction with single primary and single secondary windings to maintain electromagnetic performance characteristics.

Isolation and Safety: Isolation voltage rating of 2500VAC is mandatory for equivalent substitution.

Mechanical Compatibility: Chassis mount configuration with solder and quick connect termination style ensures physical and electrical interface compatibility.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required for substitution in regulated applications.

The Signal Transformer model 241-4-16 meets all specified criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the F4-16 and 241-4-16 are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The F4-16 (Triad Magnetics) is supplied in bulk packaging with 1092 units currently in stock. The 241-4-16 (Signal Transformer) is supplied in box packaging with 2653 units in stock, offering higher inventory availability.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical weight and isolation voltage specifications confirm mechanical and electrical interchangeability.

Physical dimensions show minor variations: the F4-16 measures 60.33mm L × 31.75mm W × 34.93mm H (seated), while the 241-4-16 measures 60.30mm L × 33.30mm W × 36.20mm H (seated). These dimensional differences are within typical manufacturing tolerances for chassis mount transformers and do not affect functional compatibility in standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 241-4-16 be used as a direct replacement for the F4-16 in existing designs?

A: Yes. Both transformers meet identical electrical specifications (115V primary, 16V secondary, 400mA output, 6VA rating) with matching core type, winding configuration, center tap presence, and isolation voltage. Both are ROHS3 compliant and REACH unaffected.

Q: Are there any dimensional compatibility concerns when substituting the 241-4-16 for the F4-16?

A: Minor dimensional differences exist. The 241-4-16 is slightly wider (33.30mm vs. 31.75mm) and taller (36.20mm vs. 34.93mm). Verify that the mounting location accommodates these variations before substitution in space-constrained applications.

Q: Do both transformers use the same termination connectors?

A: Both transformers feature solder and quick connect termination. The F4-16 specifies 0.187" (4.7mm) quick connect terminals. Confirm connector compatibility with your PCB or wiring harness design.

Q: What is the difference between packaging types (Bulk vs. Box)?

A: The F4-16 is supplied in bulk packaging, while the 241-4-16 is supplied in box packaging. This affects handling, storage, and inventory management but does not impact the transformer's electrical or mechanical performance.

Q: Are both parts suitable for applications requiring high isolation voltage?

A: Yes. Both transformers provide 2500VAC isolation voltage, meeting high-voltage isolation requirements for safety-critical and industrial applications.

Q: Can I use either part interchangeably in production?

A: Yes, provided that dimensional variations are accommodated in your mechanical design. Both parts are active production items with full regulatory compliance, making them suitable for production use.
