HC4E-PL-AC120V Equivalent & Substitute Parts

Part Overview

The HC4E-PL-AC120V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 120VAC coil. This through-hole mounted relay is designed for applications requiring multiple independent switching circuits with a 2A contact rating at 250VAC maximum switching voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4E-PL-AC120V are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a component to function as a direct substitute:

Critical Matching Parameters:

• Contact form: 4PDT (4 Form C) configuration
• Coil voltage: 120VAC
• Mounting type: Through Hole
• Termination style: PC Pin
• Coil type: Non Latching
• Must operate voltage: 96 VAC minimum
• Must release voltage: 36 VAC maximum
• Operate and release time: 20 ms

Allowable Variations:

• Contact rating current: May exceed 2A (higher current rating is acceptable for lower-current applications)
• Switching voltage: May exceed 250VAC maximum
• Coil current: May differ within acceptable operating parameters
• Operating temperature range: May be wider than the original specification
• Contact material: Alternative cadmium-free materials acceptable
• Product status: Active products preferred for ongoing availability

Engineering Selection Recommendations

The MY4N-02-AC110/120 from Omron Automation and Safety qualifies as a functional substitute for the obsolete HC4E-PL-AC120V. Both relays share identical contact form, coil voltage, mounting configuration, and switching timing specifications. The MY4N-02-AC110/120 provides enhanced specifications in several areas: higher contact current rating (3A versus 2A), extended operating temperature range (-55°C to 70°C versus -50°C to 60°C), and dual voltage switching capability (250VAC and 125VDC). The substitute part maintains RoHS compliance and carries an active product status, ensuring long-term availability and supply chain continuity. The lower coil current requirement (8.4 mA versus 11.9 mA) in the substitute may provide marginal power efficiency benefits in control circuits.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-02-AC110/120 directly replace the HC4E-PL-AC120V in existing applications?

A: Yes. Both relays share identical contact configuration (4PDT), coil voltage (120VAC), mounting type (through hole), termination style (PC pin), and switching timing (20 ms operate and release). The substitute meets or exceeds all critical electrical parameters required for functional equivalence.

Q: What is the significance of the higher 3A contact rating on the MY4N-02-AC110/120?

A: The substitute's 3A contact rating exceeds the original 2A specification. This higher rating does not affect compatibility; it indicates the substitute can safely handle equal or lower current loads. Applications originally designed for 2A operation remain fully compatible.

Q: Are there differences in coil resistance between these relays?

A: Yes. The HC4E-PL-AC120V has a coil resistance of 10.084 kOhms, while the MY4N-02-AC110/120 measures 4.43 kOhms. This difference correlates with the lower coil current requirement (8.4 mA versus 11.9 mA) in the substitute. Both values are acceptable for 120VAC coil operation and do not affect functional compatibility in standard relay circuits.

Q: Does the extended operating temperature range of the MY4N-02-AC110/120 affect compatibility?

A: No. The substitute's wider operating temperature range (-55°C to 70°C versus -50°C to 60°C) represents an enhancement. Applications operating within the original temperature specification remain fully compatible.

Q: What is the packaging difference between these parts?

A: The HC4E-PL-AC120V is supplied in standard packaging, while the MY4N-02-AC110/120 is available in bulk packaging. Both maintain identical through-hole PC pin termination suitable for printed circuit board assembly.

Q: Is the MY4N-02-AC110/120 RoHS compliant?

A: Yes. The MY4N-02-AC110/120 carries RoHS compliance certification. Both the original and substitute use cadmium-free contact materials, meeting environmental and regulatory requirements.
