HC1-H-AC120V-F Equivalent & Substitute Parts

Part Overview

The HC1-H-AC120V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 120VAC coil. This socketable relay is rated for 10A switching capacity at up to 250VAC maximum switching voltage. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where this relay is specified in existing equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-H-AC120V-F is determined by strict alignment of the following critical parameters:

• Coil voltage: 120VAC (exact match required)
• Contact configuration: SPDT (1 Form C) (exact match required)
• Contact current rating: 10A minimum (equal or higher acceptable)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In compatible (exact match required)
• Must operate and release voltages: 96VAC and 36VAC respectively (exact match required)
• Operating temperature range: Must encompass or exceed -50°C ~ 70°C

The G2R-1-S AC120(S) manufactured by Omron Automation and Safety meets all critical substitution criteria. This relay maintains identical coil voltage, contact form, current rating, socketable mounting, and plug-in termination. Voltage operation thresholds and temperature operating range are compatible with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The G2R-1-S AC120(S) is the direct substitute for the obsolete HC1-H-AC120V-F. Both relays share identical electrical specifications for coil voltage, contact configuration, current rating, and voltage operation thresholds. The Omron relay offers enhanced performance characteristics including lower coil current (7.5 mA versus 10.9 mA), faster switching times (15 ms operate, 10 ms release versus 20 ms each), and higher maximum switching voltage capability (440VAC/125VDC versus 250VAC).

The G2R-1-S AC120(S) carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The operating temperature range of -40°C ~ 70°C covers the upper portion of the original specification; applications requiring operation below -40°C should be evaluated for thermal performance impact.

Both relays utilize socketable mounting with plug-in termination, enabling direct mechanical and electrical interchange in existing socket-based installations.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-S AC120(S) directly replace the HC1-H-AC120V-F in existing equipment?

A: Yes. Both relays share identical coil voltage (120VAC), contact form (SPDT), current rating (10A), mounting type (socketable), and termination style (plug-in). Voltage operation thresholds are identical. Direct substitution is electrically and mechanically compatible.

Q: What is the difference in coil current between these relays?

A: The HC1-H-AC120V-F draws 10.9 mA, while the G2R-1-S AC120(S) draws 7.5 mA. The lower coil current of the Omron relay reduces power consumption and heat generation in the coil circuit.

Q: Are there temperature range differences?

A: The HC1-H-AC120V-F operates from -50°C to 70°C, while the G2R-1-S AC120(S) operates from -40°C to 70°C. The Omron relay does not extend to -50°C. Applications requiring operation below -40°C should retain the original specification or identify alternative solutions.

Q: What is the switching voltage difference?

A: The HC1-H-AC120V-F is rated for 250VAC maximum switching voltage. The G2R-1-S AC120(S) is rated for 440VAC or 125VDC maximum switching voltage. The Omron relay provides higher voltage switching capability, making it suitable for applications with higher switching voltage requirements.

Q: Does the G2R-1-S AC120(S) meet current regulatory standards?

A: Yes. The G2R-1-S AC120(S) is ROHS3 compliant and carries active product status, ensuring compliance with current environmental and regulatory requirements.

Q: Are the switching times identical?

A: No. The HC1-H-AC120V-F has 20 ms operate and 20 ms release times. The G2R-1-S AC120(S) has 15 ms operate and 10 ms release times. The Omron relay switches faster, which may affect timing-sensitive applications.

Q: Can I use the G2R-1-S AC120(S) in applications with switching voltages above 250VAC?

A: Yes, up to 440VAC or 125VDC. The G2R-1-S AC120(S) supports higher switching voltages than the original HC1-H-AC120V-F specification.
