HC2-HPL-AC24V-F Equivalent & Substitute Parts

Part Overview

The HC2-HPL-AC24V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 24VAC coil. This through-hole mounted relay is designed for applications requiring 7A contact switching at up to 250VAC. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC2-HPL-AC24V-F is determined by the following critical parameters:

• Coil Voltage: Must be 24VAC to ensure direct compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to maintain circuit switching functionality
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Termination Style: Must be PC pin for direct socket or PCB pad connection
• Coil Type: Must be non-latching for standard relay operation
• Contact Rating: Must support minimum 7A switching capacity
• Switching Voltage: Must support 250VAC maximum switching voltage

The Weidmüller 8870210000 meets all mandatory substitution criteria. While it provides enhanced performance characteristics (8A contact rating versus 7A, faster switching times, improved operating temperature range), these represent functional improvements rather than deviations from the core electrical and mechanical requirements.

Engineering Selection Recommendations

The Weidmüller 8870210000 is a direct functional substitute for the obsolete HC2-HPL-AC24V-F. Selection should be based on the following factors:

Product Availability: The HC2-HPL-AC24V-F is obsolete with no ongoing manufacturing. The Weidmüller 8870210000 is an active product with established supply chain availability.

Compliance Status: Both components share identical ECCN (EAR99) and HTSUS classifications. The Weidmüller part carries RoHS Compliance and REACH Unaffected certifications, meeting modern regulatory requirements.

Electrical Compatibility: The Weidmüller substitute operates within the same 24VAC coil voltage specification and maintains DPDT contact configuration. The 8A contact rating exceeds the 7A requirement of the original part, providing margin for application demands.

Operational Characteristics: The Weidmüller part demonstrates faster switching response (10ms operate, 4ms release versus 20ms for both parameters on the original) and lower coil current draw (31.6mA versus 50mA), reducing control circuit power requirements.

Temperature Performance: The Weidmüller part extends the upper operating temperature limit to 70°C compared to 60°C for the original, while maintaining the lower limit at -40°C versus -50°C.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8870210000 directly replace the HC2-HPL-AC24V-F without circuit modification?

A: Yes. Both relays share identical coil voltage (24VAC), contact form (DPDT), mounting type (through-hole), and termination style (PC pin). Direct substitution is electrically and mechanically compatible.

Q: What are the key differences between these two relays?

A: The primary differences are contact current rating (8A versus 7A), switching speed (faster on the Weidmüller), coil current consumption (lower on the Weidmüller), and operating temperature range (extended on the Weidmüller). These represent performance enhancements rather than compatibility issues.

Q: Does the lower coil current of the Weidmüller part affect circuit design?

A: The Weidmüller part requires less coil current (31.6mA versus 50mA). This reduces power dissipation in the control circuit and may improve overall system efficiency. Existing control circuits designed for the original 50mA specification will operate the substitute without modification.

Q: Are there packaging differences between these parts?

A: The HC2-HPL-AC24V-F is specified with "-" packaging notation. The Weidmüller 8870210000 is supplied in bulk packaging. Physical dimensions and pin configurations remain compatible for through-hole PCB mounting.

Q: What contact material differences exist, and do they affect performance?

A: The original uses silver alloy (cadmium-free) contacts, while the Weidmüller uses silver nickel (AgNi). Both materials are suitable for general-purpose relay applications at the specified switching voltage and current ratings. Contact material selection does not impact substitution compatibility.

Q: Is the Weidmüller part RoHS compliant?

A: Yes. The Weidmüller 8870210000 carries RoHS Compliance certification and REACH Unaffected status, meeting current environmental and regulatory standards.
