Hammond Manufacturing 182L18 Toroidal Power Transformer - Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 182L18 is an 80VA toroidal power transformer designed for chassis mount applications. It features dual primary windings (117V, 234V) and dual secondary windings (parallel 18V or series 36V configuration), with a maximum output current of 4.44A in parallel mode or 2.22A in series mode. The transformer provides 4000Vrms isolation and is terminated with wire leads.

The 182L18 is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing maintenance, repair, and new design implementations where this transformer specification is required.

Key Parameters

Substitute Part Grouping Explanation

The Hammond Manufacturing 1182L18 is identified as the manufacturer-recommended substitute for the 182L18. Substitution eligibility is determined by the following critical parameters:

• Power Rating: Both parts are rated at 80VA
• Transformer Type: Both are toroidal construction
• Primary Voltage Configuration: Both support 117V and 234V dual primary windings
• Secondary Voltage Output: Both provide parallel 18V and series 36V configurations
• Output Current Capacity: Both deliver 4.44A (parallel) and 2.22A (series)
• Winding Configuration: Both feature dual primary and dual secondary windings
• Mounting and Termination: Both are chassis mount with wire lead termination
• Voltage Isolation: Both provide 4000Vrms isolation
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

The primary distinction between the 182L18 and 1182L18 is product status: the 182L18 is obsolete while the 1182L18 is active production. The 1182L18 represents the current generation equivalent with identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 1182L18 is the direct equivalent substitute for the obsolete 182L18. Both parts meet identical electrical specifications and regulatory requirements (ROHS3 compliant, REACH unaffected). The 1182L18 is currently in active production with confirmed inventory availability.

Physical dimensions show minor variation: the 1182L18 has a maximum seated height of 38.10mm compared to 30.61mm for the 182L18, and a slightly lower weight (2.1 lbs versus 2.2 lbs). These dimensional differences must be evaluated against available mounting space in the target application.

For new designs or ongoing production requiring this transformer specification, the 1182L18 is the appropriate selection due to its active product status and full compliance with the same electrical and isolation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1182L18 directly replace the 182L18 in existing applications?

A: Yes, from an electrical standpoint. Both transformers provide identical voltage configurations, current ratings, winding arrangements, and isolation specifications. Physical mounting space must be verified, as the 1182L18 has a greater maximum seated height (38.10mm versus 30.61mm).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: power rating (80VA), transformer type (toroidal), primary voltage options (117V/234V), secondary voltage outputs (18V parallel, 36V series), output current capacity (4.44A parallel, 2.22A series), winding configuration (dual primary, dual secondary), mounting type (chassis mount), termination style (wire leads), and voltage isolation (4000Vrms).

Q: Why is the 182L18 listed as obsolete?

A: The 182L18 has been superseded by the 1182L18 in Hammond Manufacturing's product line. The 1182L18 maintains identical electrical specifications while representing the current generation offering.

Q: Are there packaging differences between these parts?

A: Yes. The 182L18 is listed with no specified packaging designation, while the 1182L18 is supplied in box packaging. This affects handling, storage, and logistics but does not impact electrical performance or compatibility.

Q: What compliance certifications apply to both parts?

A: Both the 182L18 and 1182L18 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and the same HTSUS code (8504.31.4065).
