Key Parameters

Substitute Part Grouping Explanation

Substitution of the 182T117 is based on the following critical electrical and mechanical parameters:

• Power Rating: 1500VA capacity must be maintained
• Voltage Configuration: Dual primary (117V/234V) and dual secondary (Parallel 117V/Series 234V) windings required
• Output Current: Parallel 12.8A and Series 6.4A specifications must be met
• Transformer Type: Toroidal construction
• Mounting Interface: Chassis mount configuration
• Termination: Wire leads connection method
• Isolation Voltage: 4000Vrms minimum
• Regulatory Compliance: ROHS3 and REACH compliance maintained

The Hammond Manufacturing 1182T117P meets all these criteria and is identified as a direct substitute for the obsolete 182T117 model.

Parameter Comparison

Engineering Selection Recommendations

The 1182T117P is the direct substitute for the obsolete 182T117. Both units maintain identical electrical specifications including 1500VA power rating, dual voltage primary and secondary configurations, and 4000Vrms isolation voltage. The substitute part is currently in active production status, ensuring availability for replacement and new applications.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The 1182T117P offers a marginal weight reduction (0.4 lbs) and improved packaging in box format compared to the original specification. Mechanical dimensions show minor variations: the substitute has a diameter of 187.96mm and reduced seated height of 82.55mm versus the original 88.90mm maximum height, which may require verification for space-constrained chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 1182T117P directly replace the 182T117 in existing designs?

A: Yes. The 1182T117P provides electrical equivalence across all critical parameters: 1500VA power rating, dual primary/secondary windings, 117V/234V voltage configurations, 12.8A parallel and 6.4A series output currents, and 4000Vrms isolation. Mechanical compatibility requires confirmation of the reduced height dimension (82.55mm versus 88.90mm) in the specific chassis mount application.

Q: What is the primary reason for substitution?

A: The 182T117 is classified as obsolete. The 1182T117P is the active production equivalent from Hammond Manufacturing, ensuring long-term availability and supply chain continuity.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory requirements are satisfied by either part.

Q: What packaging differences exist?

A: The 182T117 specification does not define packaging format. The 1182T117P is supplied in box packaging, which is standard for active production units.

Q: Are there dimensional considerations for substitution?

A: The 1182T117P has a seated height of 82.55mm compared to the 182T117 maximum height of 88.90mm. This 6.35mm reduction should be verified against available chassis mount clearance in the target application. The substitute also specifies a diameter of 187.96mm.
