Equivalent & Substitute Parts for Signal Transformer 241-7-56

Part Overview

The Signal Transformer 241-7-56 is a laminated core power transformer rated at 56VA with a single primary winding (115V) and single secondary winding (56V) at 1A maximum output current. This chassis mount transformer features a center tap and dual termination options (solder and quick connect). The part is currently active in production with ROHS3 compliance and is suitable for applications requiring regulated secondary voltage output with isolation.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for this transformer category, ensuring functional interchangeability in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 241-7-56 is determined by the following critical parameters:

Primary Substitution Criteria:

• Secondary voltage output: 56V (exact match required)
• Center tap configuration: Yes (required for circuit compatibility)
• Mounting type: Chassis Mount (physical installation requirement)
• Laminated core construction (specified transformer type)
• ROHS3 compliance (regulatory requirement)

Secondary Compatibility Factors:

• Primary voltage: 115V minimum (single or dual primary acceptable if 115V is supported)
• Output current capacity: ≥1A (equal or higher capacity acceptable)
• Power rating: ≥56VA (equal or higher rating acceptable)
• Termination style: Solder and/or Quick Connect (both acceptable)
• Isolation voltage: ≥2500V (equal or higher acceptable)

Two substitute parts meet these criteria: Hammond Manufacturing 186F56 and Triad Magnetics F7-56.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): Triad Magnetics F7-56 provides the closest electrical and mechanical match to the 241-7-56. Both transformers share identical primary voltage (115V), secondary voltage (56V), output current (1A), power rating (56VA), and isolation voltage (2500V). Physical dimensions are nearly identical (93.65mm L × 46.02mm W vs. 93.70mm L × 49.20mm W). Both are ROHS3 compliant and active products. The F7-56 is suitable for direct substitution in applications where the original 241-7-56 is specified.

Higher Capacity Alternative: Hammond Manufacturing 186F56 offers increased output capacity (1.8A, 100.8VA) with dual primary winding support (115V/230V). This part meets all substitution criteria but features lower isolation voltage (2000Vrms vs. 2500Vrms). The 186F56 is appropriate for applications requiring higher current delivery or dual-voltage primary input, provided the lower isolation rating is acceptable for the target circuit. Physical dimensions are larger (102.36mm L × 66.68mm W).

All three transformers maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Hammond Manufacturing 186F56 replace the Signal Transformer 241-7-56 in all applications? A: The 186F56 meets core substitution criteria (56V secondary, center tap, chassis mount, ROHS3 compliant) but has lower isolation voltage (2000Vrms vs. 2500Vrms). Substitution is valid only if the application circuit does not require 2500Vrms isolation. The higher current capacity (1.8A vs. 1A) and power rating (100.8VA vs. 56VA) are compatible with designs expecting the original 56VA transformer.

Q: What is the difference between the Triad Magnetics F7-56 and the Signal Transformer 241-7-56? A: Electrical specifications are equivalent: both provide 115V primary, 56V secondary at 1A maximum output, 56VA power rating, center tap, and 2500V isolation. Physical dimensions are nearly identical. The primary difference is manufacturer and series designation (Quick Pack vs. Two-4-One™). Both are suitable for direct substitution.

Q: Are there physical installation differences between these three transformers? A: All three are chassis mount transformers with similar footprints. The 241-7-56 and F7-56 have comparable dimensions (approximately 93.7mm × 46-49mm × 57mm). The 186F56 is larger (102.36mm × 66.68mm × 65.02mm) and may require layout verification before installation. Termination connectors are compatible across all three (solder and quick connect options).

Q: Do all three transformers support the same termination methods? A: Yes. All three transformers provide both solder and quick connect termination options. The F7-56 specifies quick connect as 0.187" (4.7mm) diameter, which is standard for this transformer category and compatible with the other two parts.

Q: Are there compliance or regulatory differences between these parts? A: All three transformers are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. Regulatory status is equivalent across all three parts.
