HC1-L-DC48V-D-F Equivalent & Substitute Parts

Part Overview

The HC1-L-DC48V-D-F is a general purpose relay manufactured by Panasonic Electric Works with SPDT (1 Form C) contact configuration and 48VDC coil voltage. This socketable relay is rated for 10A switching current and features a diode and lighted indicator. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC1-L-DC48V-D-F are identified based on the following critical parameters that must match or exceed the original specification:

• Coil voltage: 48VDC (exact match required)
• Contact form: SPDT (1 Form C) configuration
• Contact rating: 10A minimum
• Mounting type: Socketable
• Termination style: Plug In compatible
• Coil type: Non Latching
• Operating temperature range: Must encompass or exceed -50°C ~ 60°C

The G2R-1-SD DC48(S) from Omron Automation and Safety meets these core substitution criteria. Both relays share identical coil voltage, contact configuration, current rating, and socketable mounting characteristics. The Omron substitute maintains plug-in termination compatibility and non-latching coil operation.

Engineering Selection Recommendations

The G2R-1-SD DC48(S) is the designated substitute for the obsolete HC1-L-DC48V-D-F. Selection is based on:

• Active product status: The Omron relay is currently in active production, ensuring long-term availability and supply chain continuity.
• Compliance certifications: The G2R-1-SD DC48(S) carries RoHS3 compliance and REACH affected status, meeting current regulatory requirements.
• Functional equivalence: Both relays share identical coil voltage, contact configuration, current rating, and socketable mounting architecture.
• Enhanced switching capability: The Omron substitute provides higher maximum switching voltage (440VAC, 125VDC) compared to the original (250VAC), offering greater application flexibility.
• Improved coil efficiency: The substitute operates at lower coil current (11.4 mA vs. 18.5 mA), reducing power consumption in control circuits.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-SD DC48(S) be used as a direct replacement for the HC1-L-DC48V-D-F?

A: Yes. Both relays share identical 48VDC coil voltage, SPDT contact configuration, 10A current rating, and socketable mounting type. The Omron substitute maintains plug-in termination compatibility required for socket-based installations.

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

A: The primary differences are coil current (11.4 mA vs. 18.5 mA), maximum switching voltage (440VAC/125VDC vs. 250VAC), operating temperature range (-40°C ~ 70°C vs. -50°C ~ 60°C), and coil resistance (4.22 kOhms vs. 2.6 kOhms). The Omron relay also features faster operate time (15 ms vs. 20 ms).

Q: Are there packaging considerations for this substitution?

A: The HC1-L-DC48V-D-F is available in standard packaging, while the G2R-1-SD DC48(S) is supplied in bulk packaging. Both maintain socketable form factor compatibility. Verify socket compatibility with your specific relay base before installation.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The G2R-1-SD DC48(S) is RoHS3 compliant and REACH affected, meeting current environmental and safety regulations. The original HC1-L-DC48V-D-F is obsolete and no longer subject to active compliance updates.

Q: What is the impact of different coil resistance values?

A: The Omron substitute has higher coil resistance (4.22 kOhms vs. 2.6 kOhms). This affects coil current draw and may require circuit verification to ensure proper operation with existing control electronics. The lower coil current of the substitute generally reduces power consumption.
