Hammond Manufacturing 182R117 Toroidal Power Transformer - Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 182R117 is a 1000VA toroidal power transformer designed for chassis mount applications. This transformer features dual primary and secondary windings, supporting multiple voltage configurations (117V or 234V primary, with parallel or series secondary output options). The part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity.

Substitute Part Grouping Explanation

Substitution of the 182R117 is based on the following critical parameters that must remain constant:

• Power Rating: 1000VA (exact match required)
• Transformer Type: Toroidal configuration
• Primary Voltage Options: 117V and 234V dual winding support
• Secondary Voltage Configuration: Parallel 117V and Series 234V output capability
• Output Current Specifications: Parallel 8.6A and Series 4.3A maximum ratings
• Winding Configuration: Dual primary and dual secondary windings
• Mounting Interface: Chassis mount with wire lead termination
• Isolation Voltage: 4000Vrms dielectric strength
• Regulatory Compliance: ROHS3 and REACH requirements

The Hammond Manufacturing 1182R117 qualifies as a direct substitute based on identical electrical specifications and functional parameters. The primary distinction is product status transition from obsolete to active production, along with packaging format change and minor dimensional modifications that do not affect electrical performance or mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 1182R117 is the manufacturer-recommended substitute for the obsolete 182R117. Both units maintain identical electrical specifications, power handling capacity, and voltage configurations. The transition from the 182 series to the 1182 series reflects Hammond Manufacturing's product line evolution while preserving functional equivalence.

Selection of the 1182R117 is supported by:

• Active production status ensuring long-term availability and supply chain continuity
• Identical electrical performance across all operating modes (parallel and series configurations)
• Maintained compliance with ROHS3 and REACH regulatory frameworks
• Consistent isolation voltage rating and dielectric strength specifications
• Equivalent weight and thermal characteristics for thermal management calculations
• Dimensional compatibility with chassis mount installations (reduced height may provide installation advantages)

Frequently Asked Questions (FAQ)

Q: Can the 1182R117 directly replace the 182R117 in existing installations?

A: Yes. The 1182R117 provides electrical equivalence across all parameters: 1000VA power rating, dual primary/secondary winding configuration, 117V/234V voltage support, and 4000Vrms isolation. Wire lead termination and chassis mount interface are identical. The reduced seated height (73.15mm vs. 88.90mm) may require clearance verification in space-constrained applications.

Q: What is the primary difference between these two part numbers?

A: The 182R117 is obsolete; the 1182R117 is active production. The series designation change (182 to 1182) reflects Hammond Manufacturing's product line update. Electrical specifications and functional performance are equivalent.

Q: Are there compliance or certification differences?

A: Both units carry ROHS3 compliance and REACH unaffected status. ECCN and HTSUS classifications are identical (EAR99 and 8504.31.4065 respectively).

Q: Does packaging format affect electrical performance?

A: No. The 182R117 ships in bulk packaging; the 1182R117 ships in box packaging. Packaging format does not alter transformer specifications, performance, or compatibility.

Q: What voltage configurations are supported by the substitute?

A: The 1182R117 supports identical configurations: primary input of 117V or 234V, with secondary output options of parallel 117V (8.6A maximum) or series 234V (4.3A maximum).

Q: Is the 1182R117 suitable for new designs?

A: Yes. Active production status, full regulatory compliance, and established supply availability make the 1182R117 appropriate for new equipment designs requiring 1000VA toroidal transformer functionality.
