HC4E-HTM-AC115V Equivalent & Substitute Parts

Part Overview

The HC4E-HTM-AC115V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 115VAC coil voltage and 2A contact rating. This socketable relay is designed for plug-in termination applications requiring non-latching operation across industrial and commercial control systems.

The HC4E-HTM-AC115V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and replacement requirements for installed equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4E-HTM-AC115V are selected based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Contact form must be 4PDT (4 Form C)
• Coil voltage must be 115VAC or 120VAC (within standard utility voltage tolerance)
• Mounting type must be socketable with plug-in termination
• Coil type must be non-latching
• Operating temperature range must encompass or exceed the original specification

Allowable Parameter Variations:

• Contact rating (current) may exceed 2A, as higher ratings provide equivalent or superior performance
• Switching voltage may exceed 250VAC maximum
• Coil current and resistance variations are acceptable within the same voltage class
• Must operate and release voltages may vary within acceptable control system tolerances

The identified substitutes meet these criteria while offering active product status and improved availability.

Engineering Selection Recommendations

MY4 AC110/120 (S) - Omron Automation and Safety

The MY4 AC110/120 (S) is an active product offering direct functional compatibility with the HC4E-HTM-AC115V. The 120VAC coil voltage operates within standard North American utility voltage tolerance relative to the original 115VAC specification. The 3A contact rating exceeds the original 2A requirement, providing margin for load variations. This substitute is RoHS Compliant and maintains the same 20ms operate and release times as the original part. The extended operating temperature range (-55°C ~ 70°C) provides improved thermal performance. Current inventory availability is 1221 units.

PT580615 - TE Connectivity Potter & Brumfield Relays

The PT580615 is an active product providing direct functional compatibility with the HC4E-HTM-AC115V. The 115VAC coil voltage matches the original specification exactly. The 6A contact rating significantly exceeds the original 2A requirement, offering substantial performance margin. This substitute includes mechanical indicator and test button features and supports both standard plug-in and quick connect termination options. The part is ROHS3 Compliant and extends the operating temperature range to -40°C ~ 70°C. Current inventory availability is 1533 units.

Both substitutes maintain socketable mounting, 4PDT contact configuration, non-latching coil operation, and plug-in termination compatibility with the original HC4E-HTM-AC115V.

Frequently Asked Questions (FAQ)

Q: Can the MY4 AC110/120 (S) be used as a direct replacement for the HC4E-HTM-AC115V?

A: Yes. Both relays feature 4PDT contact configuration, socketable mounting, plug-in termination, and non-latching operation. The 120VAC coil voltage is compatible with 115VAC control circuits within standard utility voltage tolerance. The 3A contact rating exceeds the original 2A specification.

Q: What is the difference between the MY4 AC110/120 (S) and PT580615 substitutes?

A: The primary differences are contact rating (3A versus 6A), coil voltage (120VAC versus 115VAC), and available termination options. The PT580615 includes mechanical indicator and test button features. Both are functionally compatible with the HC4E-HTM-AC115V. Selection depends on specific load requirements and control circuit voltage specifications.

Q: Are there any compatibility concerns with the higher contact ratings of the substitute parts?

A: No. Higher contact ratings are compatible with applications requiring the original 2A rating. The substitute parts can safely handle loads at or below the original specification.

Q: Do the substitute parts require socket modifications?

A: No. Both the MY4 AC110/120 (S) and PT580615 are socketable relays with plug-in termination compatible with standard relay sockets designed for the HC4E-HTM-AC115V.

Q: What is the coil voltage tolerance for the MY4 AC110/120 (S) in 115VAC circuits?

A: The MY4 AC110/120 (S) is rated for 120VAC coil voltage. Standard North American utility voltage tolerance is ±10%, making 115VAC operation within acceptable parameters for this relay class.

Q: Are the substitute parts RoHS compliant?

A: Yes. The MY4 AC110/120 (S) is RoHS Compliant. The PT580615 is ROHS3 Compliant. Both meet current environmental compliance requirements.
