Equivalent & Substitute Parts for Signal Transformer 241-5-56

Part Overview

The Signal Transformer 241-5-56 is a laminated core power transformer rated at 12VA with a 115V primary and 56V secondary output. This chassis mount transformer is designed for applications requiring regulated secondary voltage with center tap configuration. The part is currently active in production with full RoHS3 compliance and 2500Vrms isolation rating. Substitute parts may be required due to inventory availability, lead time constraints, or application-specific performance requirements within compatible electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the 241-5-56 are qualified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Voltage - Primary: 115V (direct match required)
• Voltage - Secondary: 56V (direct match required)
• Center Tap: Yes (configuration must be maintained)
• Mounting Type: Chassis Mount (form factor requirement)
• Termination Style: Solder, Quick Connect (interface compatibility)
• Type: Laminated Core (core construction type)

Secondary Compatibility Factors:

• Current - Output (Max): 220mA minimum (equal or greater capacity acceptable)
• Power - Max: 12VA minimum (equal or greater capacity acceptable)
• Voltage - Isolation: 2500Vrms minimum (equal or greater isolation acceptable)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

The substitute parts listed below meet or exceed all primary criteria and maintain compatibility with the original 241-5-56 specification.

Parameter Comparison

Engineering Selection Recommendations

F5-56 (Triad Magnetics - Quick Pack Series)

The F5-56 provides direct electrical equivalence to the 241-5-56 with identical voltage ratings, current capacity, and power rating. Physical dimensions are nearly identical (71.42mm vs 71.40mm length, 34.93mm vs 36.30mm width), and height is slightly reduced at 41.28mm. Termination connectors are specified as 0.187" (4.7mm) quick connect, maintaining compatibility with standard chassis mount applications. Both parts carry ROHS3 compliance and equivalent isolation ratings. This substitute is suitable for direct replacement in applications where the original 241-5-56 is specified.

186D56 (Hammond Manufacturing - 186 Series)

The 186D56 exceeds the electrical specifications of the 241-5-56 with 30VA power rating and 530mA maximum output current, providing 2.5x capacity margin. The primary winding is dual-configuration, supporting both 115V and 230V input, offering broader application flexibility. Physical dimensions are larger (82.55mm length, 52.20mm width, 49.02mm height) and weight is increased to 1.3 lbs. Isolation voltage is rated at 2000Vrms, which is lower than the 241-5-56 but remains within acceptable industrial standards. This substitute is appropriate for applications requiring higher power capacity or dual-voltage primary input capability, provided chassis space accommodates the larger form factor.

Frequently Asked Questions (FAQ)

Q: Can the F5-56 be used as a direct replacement for the 241-5-56?

A: Yes. The F5-56 matches all critical electrical parameters: 115V primary, 56V secondary, 220mA output current, 12VA power rating, center tap configuration, and chassis mount termination. Physical dimensions are nearly identical, and both parts are ROHS3 compliant with equivalent isolation ratings.

Q: What are the advantages of using the 186D56 over the 241-5-56?

A: The 186D56 provides higher power capacity (30VA vs 12VA) and output current (530mA vs 220mA), allowing operation at higher load levels. The dual primary winding supports both 115V and 230V input voltages, enabling use in international applications. These features come with increased physical size and weight.

Q: Are there any mechanical compatibility concerns with the 186D56?

A: The 186D56 has larger dimensions (82.55mm x 52.20mm x 49.02mm) compared to the 241-5-56 (71.40mm x 36.30mm x 42.80mm). Chassis space must be verified before substitution. All three parts use identical mounting type (chassis mount) and termination style (solder, quick connect).

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. The F5-56 and 186D56 are both ROHS3 compliant and REACH unaffected, matching the regulatory status of the 241-5-56. All three parts carry EAR99 ECCN classification.

Q: What is the difference in isolation voltage between these transformers?

A: The 241-5-56 and F5-56 are rated at 2500Vrms/2500VAC isolation. The 186D56 is rated at 2000Vrms. For applications requiring 2500V isolation, the 241-5-56 or F5-56 must be used. For applications with 2000V isolation requirements, the 186D56 is acceptable.

Q: Can the 186D56 be used in space-constrained applications?

A: No. The 186D56 is significantly larger than the 241-5-56. If chassis space is limited, the F5-56 is the appropriate substitute, as it maintains nearly identical physical dimensions to the original part.
