HC2-HP-AC24V Equivalent & Substitute Parts

Part Overview

The Panasonic Electric Works HC2-HP-AC24V is a general purpose relay with DPDT (2 Form C) contact configuration and 24VAC coil voltage, rated for 7A switching current. This through-hole mounted relay is classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations. The HC series relay provides reliable switching performance across industrial control applications requiring dual-pole, dual-throw functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the HC2-HP-AC24V are identified based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Coil voltage: 24VAC
• Contact configuration: DPDT (2 Form C)
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Contact material: Silver or silver alloy

Secondary Compatibility Factors:

• Must operate voltage: 19.2 VAC minimum
• Must release voltage: 7.2 VAC maximum
• Switching voltage capability: 250VAC or higher
• Operating temperature range: Must encompass or exceed -50°C to 70°C

The MY2-02-AC24 from Omron Automation and Safety meets these substitution criteria. While the contact current rating differs (5A versus 7A), this represents a derating condition acceptable in applications where the original 7A specification exceeds actual circuit requirements.

Engineering Selection Recommendations

The MY2-02-AC24 serves as a functional substitute for the obsolete HC2-HP-AC24V based on matching electrical and mechanical specifications. Key selection considerations:

Advantages of MY2-02-AC24:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance provides regulatory alignment for new designs
• Extended lower operating temperature limit (-55°C versus -50°C) offers broader environmental coverage
• Dual voltage switching capability (250VAC and 125VDC) provides application flexibility

Design Derating Consideration: The MY2-02-AC24 contact current rating of 5A represents a reduction from the original 7A specification. This substitution is valid only when actual circuit current requirements do not exceed 5A. Applications requiring the full 7A switching capacity must identify alternative components with matching current ratings.

Compliance Status: Both components carry REACH Unaffected and EAR99 ECCN classifications. The MY2-02-AC24 RoHS compliance status provides additional regulatory advantage for applications subject to RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can the MY2-02-AC24 directly replace the HC2-HP-AC24V in existing designs?

A: Direct replacement is possible when circuit current requirements do not exceed 5A. The MY2-02-AC24 maintains identical coil voltage, contact configuration, mounting type, and termination style. Verify that your application current does not exceed the 5A rating before implementation.

Q: What is the significance of the contact current rating difference?

A: The HC2-HP-AC24V is rated for 7A switching current, while the MY2-02-AC24 is rated for 5A. This represents a derating condition. If your circuit operates at or below 5A, the substitute is appropriate. If your circuit requires 5A to 7A switching capacity, alternative components must be evaluated.

Q: Are the timing characteristics compatible?

A: The MY2-02-AC24 exhibits longer operate and release times (20 ms each) compared to the HC2-HP-AC24V (10 ms each). Applications with timing-critical switching requirements must account for this 10 ms difference in response time.

Q: Does the MY2-02-AC24 support the same switching voltages?

A: The MY2-02-AC24 supports both 250VAC and 125VDC switching, providing broader voltage compatibility than the HC2-HP-AC24V specification of 250VAC maximum. This expanded capability does not create compatibility issues for applications using 250VAC switching.

Q: What is the impact of the extended operating temperature range?

A: The MY2-02-AC24 operating range of -55°C to 70°C encompasses the HC2-HP-AC24V range of -50°C to 70°C. This extended lower temperature limit provides additional environmental margin without affecting applications within the original temperature specification.

Q: Are there packaging differences between these components?

A: Both components use through-hole PC pin termination suitable for printed circuit board mounting. The HC2-HP-AC24V was supplied in standard packaging, while the MY2-02-AC24 is available in bulk packaging. Verify packaging requirements for your procurement process.
