HC1-HP-AC240V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-AC240V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 240VAC coil voltage and 10A contact rating. This through-hole mounted relay is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part operates within a temperature range of -50°C to 70°C and utilizes silver alloy, cadmium-free contact material.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-HP-AC240V-F is determined by strict alignment of the following critical parameters:

Coil voltage must be 240VAC to ensure direct compatibility with existing circuit designs without modification. Contact form must remain SPDT (1 Form C) to maintain identical switching functionality. Mounting type must be through-hole to ensure mechanical fit within existing PCB layouts. Termination style must be PC pin for direct connection compatibility.

The substitute part LY1-0-AC220/240 meets these core requirements. Additional parameters that support substitution include matching must-operate and must-release voltage thresholds (192 VAC and 72 VAC respectively), non-latching coil type, and silver alloy contact material. The substitute part demonstrates higher contact current rating (15A versus 10A), which provides additional design margin without creating incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The LY1-0-AC220/240 is a direct substitute for the HC1-HP-AC240V-F based on matching electrical and mechanical specifications. The substitute part carries active product status from Omron Automation and Safety, ensuring ongoing availability and supply chain stability compared to the obsolete Panasonic part.

The substitute part demonstrates RoHS compliance, providing environmental regulatory alignment for new designs and manufacturing processes. Both parts carry identical moisture sensitivity level (MSL 1) and ECCN classification (EAR99), supporting equivalent handling and logistics requirements.

The substitute part's higher contact current rating (15A versus 10A) and extended switching voltage capability (250VAC and 125VDC versus 250VAC only) provide additional operational margin. The slightly reduced coil current (4.6 mA versus 5 mA) and marginally increased switching times (25 ms versus 20 ms) remain within acceptable tolerances for general purpose relay applications.

Frequently Asked Questions (FAQ)

Q: Can the LY1-0-AC220/240 be used as a direct replacement for the HC1-HP-AC240V-F without circuit modification?

A: Yes. Both parts share identical coil voltage (240VAC), contact form (SPDT), mounting type (through-hole), termination style (PC pin), must-operate voltage (192 VAC), and must-release voltage (72 VAC). Direct substitution is supported without circuit redesign.

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

A: The substitute part offers higher contact current rating (15A versus 10A), extended switching voltage capability (includes 125VDC), lower coil current (4.6 mA versus 5 mA), slightly longer switching times (25 ms versus 20 ms), narrower operating temperature range (-25°C to 55°C versus -50°C to 70°C), and active product status with RoHS compliance.

Q: Does the operating temperature range difference affect substitution suitability?

A: The substitute part's operating temperature range (-25°C to 55°C) is narrower than the original part (-50°C to 70°C). Substitution is appropriate for applications operating within the substitute part's specified temperature limits. Applications requiring operation below -25°C or above 55°C require evaluation against specific system requirements.

Q: Are there packaging differences between these parts?

A: The original part is packaged as individual units with 755 pieces in stock. The substitute part is supplied in bulk packaging with 929 pieces available. Both utilize identical through-hole PC pin termination suitable for standard PCB assembly processes.

Q: What is the significance of the substitute part's RoHS compliance?

A: RoHS compliance indicates the substitute part meets environmental restrictions on hazardous substances, supporting regulatory requirements for manufacturing and end-of-life disposal. This provides advantage for new designs and systems subject to environmental compliance mandates.
