Hammond Manufacturing 182P22 Toroidal Power Transformer - Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 182P22 is a 225VA toroidal power transformer designed for chassis mount applications. It features dual primary windings (117V, 234V) and dual secondary windings (parallel 22V, series 44V) with a maximum output current of 10.22A in parallel configuration. The part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

The Hammond Manufacturing 1182P22 qualifies as a direct substitute for the 182P22 based on the following critical parameters:

• Identical power rating: 225VA
• Matching primary voltage options: 117V, 234V
• Matching secondary voltage outputs: Parallel 22V, Series 44V
• Identical maximum output currents: Parallel 10.22A, Series 5.11A
• Same transformer type: Toroidal
• Identical winding configurations: Dual primary, dual secondary
• Same mounting type: Chassis Mount
• Identical termination style: Wire Leads
• Matching isolation voltage: 4000Vrms
• Equivalent compliance: ROHS3 Compliant

The primary distinction is product status: the 182P22 is obsolete, while the 1182P22 is active production. The 1182P22 represents the current generation equivalent within the Hammond Manufacturing toroidal transformer product line.

Parameter Comparison

Engineering Selection Recommendations

The 1182P22 is the manufacturer-recommended substitute for the obsolete 182P22. Both parts maintain identical electrical specifications across all critical parameters: power rating, voltage configurations, current ratings, and isolation characteristics. Both are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The 1182P22 offers the advantage of active production status, ensuring availability and supply chain continuity. Minor physical differences (height reduced by 0.51mm, weight reduced by 0.2 lbs) reflect manufacturing improvements in the current generation and do not affect functional compatibility in chassis mount applications.

For new designs or system replacements, the 1182P22 is the appropriate selection. For legacy system repairs where original 182P22 inventory is unavailable, the 1182P22 provides direct functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 1182P22 directly replace the 182P22 in existing applications?

A: Yes. The 1182P22 provides identical electrical performance across all specified parameters: power rating, primary and secondary voltages, output currents, winding configurations, and isolation voltage. Both are chassis mount with wire lead termination.

Q: What is the significance of the product status change from obsolete to active?

A: The 182P22 is no longer manufactured. The 1182P22 is the current production equivalent, ensuring long-term availability and supply chain reliability for new procurements and system maintenance.

Q: Are there physical compatibility concerns between the two parts?

A: The 1182P22 is marginally smaller (0.51mm lower height, 0.2 lbs lighter) than the 182P22. These differences reflect manufacturing refinements and do not affect chassis mount installation or electrical performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 182P22 and 1182P22 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What packaging differences exist between these parts?

A: The 182P22 was supplied with standard packaging. The 1182P22 is supplied in a box. This distinction affects only procurement and logistics, not functional performance.
