Equivalent & Substitute Parts for Signal Transformer 241-4-36

Part Overview

The Signal Transformer 241-4-36 is a laminated core power transformer rated at 6VA with a 115V primary and 36V secondary output. This chassis-mounted transformer is designed for applications requiring isolated 36V power delivery at up to 170mA output current. The part is currently active in production with full RoHS3 compliance and 2500Vrms isolation rating. Substitute parts may be required due to inventory constraints, end-of-life considerations, or application-specific performance requirements such as higher output current capacity or dual primary voltage support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 241-4-36 is determined by the following critical parameters:

• Secondary voltage output of 36V
• Chassis mount configuration
• Center tap availability
• Laminated core construction
• RoHS3 compliance
• Solder and quick connect termination compatibility

Two substitute parts meet these core criteria with varying performance characteristics:

186C36 (Hammond Manufacturing): Exceeds baseline specifications with 12.6VA power rating and 350mA maximum output current. Supports dual primary voltages (115V/230V) and maintains 2000Vrms isolation. Represents an upgrade path for applications requiring higher current delivery.

F4-36 (Triad Magnetics): Matches the 241-4-36 specification profile identically, providing a direct functional equivalent with 6VA power rating and 170mA output current. Maintains identical isolation voltage and termination style compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (F4-36): The Triad Magnetics F4-36 provides specification-matched performance to the 241-4-36. Both parts deliver identical 6VA power, 170mA output current, and 2500V isolation. Physical dimensions are nearly equivalent, with F4-36 measuring slightly smaller in height (34.93mm vs. 36.20mm). Both maintain RoHS3 compliance and active product status. This part is suitable for direct substitution in applications where the original specification must be preserved.

Enhanced Performance Selection (186C36): The Hammond Manufacturing 186C36 offers increased power capacity (12.6VA) and output current (350mA) while maintaining the 36V secondary voltage and center tap configuration. The dual primary winding (115V/230V) provides operational flexibility across different supply voltages. The 2000Vrms isolation rating remains adequate for most industrial applications, though it is 500V lower than the original specification. Physical dimensions are larger (71.37mm L x 43.82mm W x 41.15mm H), requiring verification of mounting space availability. This part is suitable for applications requiring higher current delivery or dual voltage input capability.

All three parts maintain active production status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can the F4-36 replace the 241-4-36 without circuit modification?

A: Yes. The F4-36 matches all critical electrical specifications: 115V primary, 36V secondary, 170mA output current, center tap configuration, and 2500V isolation. Termination style compatibility (solder and quick connect) is maintained. Physical dimensions are nearly identical, with F4-36 being slightly more compact in height.

Q: When should the 186C36 be selected instead of the F4-36?

A: The 186C36 is appropriate when the application requires output current exceeding 170mA or when dual primary voltage support (115V/230V operation) is needed. The higher 12.6VA power rating accommodates increased load demands. Verify that the larger physical footprint (71.37mm L x 43.82mm W) fits within the available mounting space.

Q: Does the 186C36 lower isolation voltage affect safety compliance?

A: The 186C36 provides 2000Vrms isolation compared to 2500Vrms in the original part. This reduction does not compromise standard industrial isolation requirements. Verify isolation voltage requirements against your specific application safety standards and regulatory requirements.

Q: Are all three parts compatible with the same PCB footprint?

A: The 241-4-36 and F4-36 have nearly identical dimensions and are footprint-compatible. The 186C36 is larger (71.37mm L x 43.82mm W x 41.15mm H) and requires verification of available mounting space before substitution.

Q: What is the difference between the packaging options?

A: The 241-4-36 and 186C36 are supplied in Box packaging. The F4-36 is supplied in Bulk packaging. This affects handling and storage but does not impact electrical performance or compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three parts—241-4-36, 186C36, and F4-36—are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
