HC4E-L-DC100V-D Equivalent & Substitute Parts

Part Overview

The HC4E-L-DC100V-D is a general purpose 4PDT relay manufactured by Panasonic Electric Works, designed for socketable mounting with a 100VDC coil. This relay features a 4 Form C contact configuration rated for 2A switching capacity at 250VAC maximum, with integrated lighted indicator functionality. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where this relay is specified in legacy equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC4E-L-DC100V-D is determined by the following critical parameters that must align or exceed the original specification:

Mandatory Matching Parameters:

• Contact form: 4PDT (4 Form C) configuration
• Mounting type: Socketable with plug-in termination
• Coil type: Non-latching operation
• Coil voltage: 100VDC nominal (acceptable range: 88VDC to 110VDC based on must-operate and must-release specifications)

Acceptable Upgrade Parameters:

• Contact rating (current): Equal to or greater than 2A
• Switching voltage: Equal to or greater than 250VAC
• Operating temperature range: Equal to or wider than -50°C ~ 60°C
• Coil current: Lower values acceptable (reduced power consumption)

The MY4N-D2 DC100/110 (S) from Omron Automation and Safety qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The MY4N-D2 DC100/110 (S) is a direct substitute for the HC4E-L-DC100V-D based on functional equivalence across all critical parameters. The substitute part is currently active in production, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

The MY4N-D2 DC100/110 (S) provides performance improvements including higher contact current rating (3A vs. 2A), lower coil current consumption (9mA vs. 11mA), and an extended operating temperature range (-55°C ~ 70°C vs. -50°C ~ 60°C). The substitute is RoHS compliant, meeting modern regulatory requirements for electronic components.

Both relays maintain identical switching characteristics (20ms operate and release times) and contact form configuration, ensuring functional compatibility in existing circuit designs. The socketable mounting and plug-in termination style are identical, allowing direct mechanical and electrical replacement without circuit board modifications.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-D2 DC100/110 (S) be used as a direct replacement for the HC4E-L-DC100V-D?

A: Yes. Both relays share identical contact form (4PDT), mounting type (socketable), termination style (plug-in), and switching timing (20ms). The substitute meets or exceeds all electrical specifications of the original component.

Q: What is the voltage compatibility between 100VDC and 110VDC coil specifications?

A: The MY4N-D2 DC100/110 (S) with 110VDC coil will operate reliably in circuits designed for 100VDC. The must-operate voltage of 88VDC and must-release voltage of 11VDC for the substitute encompass the original part's operating envelope (80VDC to 10VDC), ensuring functional compatibility across the specified voltage range.

Q: Does the higher contact current rating (3A vs. 2A) affect circuit compatibility?

A: No. A higher contact current rating indicates the substitute can safely handle greater switching loads. In applications where the original 2A rating was sufficient, the 3A-rated substitute will perform identically without adverse effects.

Q: Are there packaging or inventory considerations for this substitution?

A: The MY4N-D2 DC100/110 (S) is available in bulk packaging with active production status, providing reliable sourcing. The HC4E-L-DC100V-D is obsolete. For new designs or system repairs, the Omron substitute ensures component availability and supply chain stability.

Q: What are the compliance differences between these relays?

A: The MY4N-D2 DC100/110 (S) is RoHS compliant, meeting current environmental and regulatory standards. The HC4E-L-DC100V-D, being obsolete, does not carry current compliance certifications. For applications requiring RoHS compliance, the substitute is the appropriate choice.
