Substitute Part Grouping Explanation

The Hammond Manufacturing 1182K15 qualifies as a direct substitute for the 182K15 based on the following critical parameters:

Electrical Equivalence:

• Identical power rating: 50VA
• Matching primary voltage inputs: 117V, 234V
• Matching secondary voltage outputs: Parallel 15V, Series 30V
• Matching secondary current capacity: Parallel 3.34A, Series 1.67A
• Identical winding configuration: Dual primary, dual secondary
• Identical isolation voltage: 4000Vrms
• No center tap requirement on both units

Mechanical Compatibility:

• Same transformer type: Toroidal
• Same mounting type: Chassis Mount
• Same termination style: Wire Leads
• Compatible physical dimensions for chassis integration

Regulatory & Compliance Alignment:

• Both units maintain ROHS3 compliance
• Both classified under identical HTSUS code: 8504.31.4065
• Both assigned identical ECCN: EAR99

The 1182K15 represents an active production alternative to the obsolete 182K15, with enhanced availability and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The 1182K15 is the appropriate selection for applications currently specified with the 182K15. Both units maintain identical electrical specifications and regulatory compliance certifications. The 1182K15 offers the advantage of active production status, ensuring long-term availability and supply chain continuity.

Physical dimensions show minor variations: the 1182K15 exhibits a reduced seated height of 38.10mm compared to 43.94mm on the 182K15, and a weight reduction from 1.7 lbs to 1.5 lbs. These dimensional changes do not affect functional equivalence and may provide improved space efficiency in chassis-mounted applications.

Both transformers maintain ROHS3 compliance and identical electrical isolation ratings, supporting direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 1182K15 directly replace the 182K15 in existing applications?

A: Yes. The 1182K15 provides electrical and functional equivalence across all specified parameters: power rating, voltage inputs, voltage outputs, current capacity, winding configuration, and isolation voltage. No circuit modifications are required.

Q: What are the key differences between these two models?

A: The primary differences are product status and physical dimensions. The 182K15 is obsolete, while the 1182K15 is in active production. The 1182K15 is slightly more compact (38.10mm height versus 43.94mm) and lighter (1.5 lbs versus 1.7 lbs). Electrical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both units are ROHS3 compliant, carry identical HTSUS and ECCN classifications, and maintain the same 4000Vrms isolation voltage rating.

Q: Does the reduced height of the 1182K15 affect compatibility?

A: The reduced height of the 1182K15 (38.10mm versus 43.94mm) represents a space advantage. Existing chassis designs accommodating the 182K15 will accept the 1182K15 without modification. Verify available mounting clearance in applications with tight vertical constraints.

Q: What is the packaging difference between these models?

A: The 182K15 is supplied without specified packaging, while the 1182K15 is packaged in boxes. This distinction affects logistics and storage but does not impact electrical or mechanical performance.
