HC4-HPL-DC24V Equivalent & Substitute Parts

Part Overview

The HC4-HPL-DC24V is a general purpose 4PDT relay manufactured by Panasonic Electric Works with a 24VDC coil, rated for 5A contact current, and through-hole PC pin termination. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The relay features a lighted indicator and operates across a temperature range of -50°C to 60°C with silver nickel and gold contact materials.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4-HPL-DC24V are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Coil voltage: 24VDC
• Contact form: 4PDT (4 Form C)
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Must operate voltage: 19.2 VDC minimum
• Must release voltage: 2.4 VDC maximum

Allowable Variation Parameters:

• Contact rating current: Equal to or greater than 5A
• Switching voltage: Equal to or greater than 250VAC
• Operating temperature range: Must encompass or exceed the application requirements
• Coil current: Variation acceptable within circuit design constraints
• Operate/release time: Variation acceptable within application timing requirements

Two substitute parts meet these criteria: the LY4-0-DC24 (10A rating) and MY4N-02-DC24 (3A rating). Both maintain identical coil voltage, contact form, mounting configuration, and termination style as the original part.

Parameter Comparison

Engineering Selection Recommendations

LY4-0-DC24 (Omron Automation and Safety)

The LY4-0-DC24 is an active product with 10A contact rating, exceeding the 5A requirement of the original part. This substitute provides increased current capacity for applications requiring higher switching loads. The part is RoHS3 compliant and REACH unaffected. Operating temperature range is -25°C to 40°C, which is narrower than the original part. Coil current is elevated at 69 mA compared to 37 mA in the original. Operate and release times are 25 ms versus 20 ms in the original part.

MY4N-02-DC24 (Omron Automation and Safety)

The MY4N-02-DC24 is an active product with 3A contact rating, which is lower than the 5A requirement of the original part. This substitute is suitable only for applications with contact current requirements of 3A or less. The part is RoHS compliant and REACH unaffected. Operating temperature range is -55°C to 70°C, exceeding the original part's range. Coil current is 36.9 mA, matching the original specification. Operate and release times are 20 ms, identical to the original part. The MY4N-02-DC24 includes a lighted indicator feature, matching the original part.

Frequently Asked Questions (FAQ)

Q: Can the LY4-0-DC24 replace the HC4-HPL-DC24V in all applications?

A: The LY4-0-DC24 is electrically compatible as a direct substitute for the HC4-HPL-DC24V in applications where the contact current requirement does not exceed 10A. The higher current rating provides design margin. However, the narrower operating temperature range (-25°C to 40°C) must be verified against application requirements. The increased coil current (69 mA versus 37 mA) and slightly longer switching times (25 ms versus 20 ms) should be evaluated for circuit compatibility.

Q: Can the MY4N-02-DC24 replace the HC4-HPL-DC24V?

A: The MY4N-02-DC24 is suitable only for applications where the contact current requirement is 3A or less. The original HC4-HPL-DC24V is rated for 5A, so this substitute cannot be used in circuits requiring the full 5A capacity. For applications within the 3A limit, the MY4N-02-DC24 offers superior temperature range coverage and identical switching times.

Q: What are the key differences in coil current between these relays?

A: The HC4-HPL-DC24V draws 37 mA, the MY4N-02-DC24 draws 36.9 mA (essentially equivalent), and the LY4-0-DC24 draws 69 mA. The higher coil current in the LY4-0-DC24 reflects its higher contact current rating. Circuit design must account for the increased power consumption when using the LY4-0-DC24.

Q: Are both substitute parts currently available?

A: Yes. The LY4-0-DC24 and MY4N-02-DC24 are both active products manufactured by Omron Automation and Safety, with inventory availability documented. The original HC4-HPL-DC24V is obsolete.

Q: What compliance certifications apply to the substitute parts?

A: The LY4-0-DC24 is RoHS3 compliant and REACH unaffected. The MY4N-02-DC24 is RoHS compliant and REACH unaffected. Both parts carry EAR99 ECCN classification.
