HC1-HP-AC24V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-AC24V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 24VAC coil voltage and 10A contact rating. This through-hole mounted relay is designed for industrial control applications requiring reliable switching at 250VAC maximum switching voltage.

The HC1-HP-AC24V-F has reached obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new design implementations where this relay specification remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC1-HP-AC24V-F must satisfy the following core electrical and mechanical parameters:

• Coil voltage: 24VAC
• Contact configuration: SPDT (1 Form C)
• Mounting type: Through hole
• Termination style: PC Pin
• Coil type: Non Latching
• Must operate voltage: 19.2 VAC
• Must release voltage: 7.2 VAC

The LY1-0-AC24 from Omron Automation and Safety meets all mandatory substitution criteria. While this substitute provides higher contact current rating (15A versus 10A) and extended switching voltage capability (250VAC and 125VDC), these represent enhanced performance characteristics that do not prevent functional equivalence in applications designed for the original 10A specification.

Parameter Comparison

Engineering Selection Recommendations

The LY1-0-AC24 is the primary substitute for the HC1-HP-AC24V-F based on electrical and mechanical parameter alignment. The substitute maintains identical coil voltage, contact configuration, mounting type, and termination style. The LY1-0-AC24 carries active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and production environments.

The LY1-0-AC24 exhibits slightly lower coil current (46 mA versus 50 mA) and marginally extended switching voltage capability. Operating temperature range differs, with the substitute rated to -25°C ~ 55°C compared to the original -50°C ~ 70°C specification. Applications requiring the full original temperature range must evaluate whether the substitute's narrower range accommodates specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the LY1-0-AC24 directly replace the HC1-HP-AC24V-F in existing circuit designs?

A: The LY1-0-AC24 satisfies all mandatory electrical parameters: 24VAC coil voltage, SPDT contact form, through-hole mounting, and PC pin termination. Both relays share identical must-operate and must-release voltage thresholds. Direct substitution is electrically valid for applications within the LY1-0-AC24 operating temperature range (-25°C ~ 55°C).

Q: What are the differences in contact current rating?

A: The HC1-HP-AC24V-F is rated for 10A contact current, while the LY1-0-AC24 is rated for 15A. The substitute provides higher current capacity. Applications designed for 10A operation remain fully compatible with the 15A-rated substitute.

Q: How do the switching voltage specifications compare?

A: The HC1-HP-AC24V-F switches up to 250VAC maximum. The LY1-0-AC24 switches up to 250VAC and 125VDC maximum. Both relays meet the original 250VAC requirement, with the substitute offering additional DC switching capability.

Q: Are there timing differences between these relays?

A: The HC1-HP-AC24V-F operates and releases in 20 ms. The LY1-0-AC24 operates and releases in 25 ms. Applications with timing-critical switching requirements must account for this 5 ms difference in both operate and release times.

Q: What is the operating temperature consideration?

A: The HC1-HP-AC24V-F operates across -50°C ~ 70°C. The LY1-0-AC24 operates across -25°C ~ 55°C. If the application requires operation below -25°C or above 55°C, the substitute may not be suitable for those environmental extremes.

Q: Does the LY1-0-AC24 meet current regulatory requirements?

A: The LY1-0-AC24 carries RoHS compliance certification. The HC1-HP-AC24V-F RoHS status is not specified. For applications requiring RoHS-compliant components, the LY1-0-AC24 meets this regulatory requirement.
