Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 241-4-56 are qualified based on the following critical parameters:

• Primary Voltage: 115V input compatibility
• Secondary Voltage: 56V output specification
• Center Tap Configuration: Required for circuit compatibility
• Mounting Type: Chassis mount form factor
• Termination Style: Solder and quick connect compatibility
• Core Type: Laminated core construction
• Regulatory Compliance: ROHS3 compliance and isolation voltage rating

The substitute parts 186C56 and F4-56 meet these core electrical and mechanical requirements. The 186C56 offers higher power capacity (12.3VA vs 6VA) with dual primary winding support for 115V/230V operation. The F4-56 maintains identical electrical specifications to the main part with equivalent dimensional and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

241-4-56 (Signal Transformer): Select this part for applications requiring the original specification with 6VA power capacity and 2500Vrms isolation voltage. All regulatory certifications and compliance requirements are met.

186C56 (Hammond Manufacturing): This substitute provides higher power capacity at 12.3VA with dual primary winding support for both 115V and 230V operation. The maximum output current is 210mA, double that of the main part. Isolation voltage is rated at 2000Vrms. This part is suitable for applications requiring increased power headroom or dual-voltage input flexibility. All ROHS3 compliance requirements are satisfied.

F4-56 (Triad Magnetics): This substitute maintains electrical parity with the main part at 6VA power capacity and 110mA maximum output current. Isolation voltage is specified as 2500VAC, equivalent to the main part. Termination connectors are specified as 0.187" (4.7mm) quick connect. This part provides direct functional equivalence with identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 186C56 be used as a direct replacement for the 241-4-56?

A: The 186C56 is electrically compatible at the 115V primary and 56V secondary level. However, it provides higher power capacity (12.3VA vs 6VA) and dual primary winding support. Physical dimensions differ: 186C56 measures 71.37mm L x 43.82mm W x 41.15mm H versus 241-4-56 at 60.30mm L x 33.30mm W x 36.20mm H. Verify chassis mounting clearance before substitution.

Q: What is the difference between the F4-56 and the 241-4-56?

A: The F4-56 and 241-4-56 are functionally equivalent. Both are rated at 6VA with 115V primary, 56V secondary, 110mA maximum output, and center tap configuration. Physical dimensions are nearly identical (F4-56: 60.33mm L x 31.75mm W x 34.93mm H). The primary difference is termination connector specification: F4-56 uses 0.187" (4.7mm) quick connect terminals. Verify connector compatibility with your circuit board design.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 241-4-56, 186C56, and F4-56 are all ROHS3 compliant and REACH unaffected. All parts carry EAR99 export classification.

Q: Which substitute should I select for increased power capacity?

A: The 186C56 is rated at 12.3VA with 210mA maximum output current, providing approximately double the power capacity of the 241-4-56. This part also supports dual primary voltage operation (115V/230V). Physical size is larger, so verify mounting space availability.

Q: What is the isolation voltage difference between these parts?

A: The 241-4-56 and F4-56 are both rated at 2500V isolation (Vrms/VAC). The 186C56 is rated at 2000Vrms. For applications requiring maximum isolation voltage, the 241-4-56 or F4-56 are preferred.
