HC1-DC6V-D-F Equivalent & Substitute Parts

Part Overview

The HC1-DC6V-D-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 6VDC coil and 10A contact rating. This socketable relay is designed for general-purpose switching applications with a maximum switching voltage of 250VAC. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC1-DC6V-D-F is determined by the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be SPDT (1 Form C) to maintain identical switching functionality
• Contact Rating (Current): Must be rated for 10A minimum to handle the same load requirements
• Mounting Type: Must be socketable to fit existing relay sockets without mechanical modification
• Termination Style: Must support plug-in connection for direct socket compatibility
• Coil Type: Must be non-latching to preserve operational behavior
• Features: Must include diode protection for coil suppression

The G2R-1-SD DC6(S) from Omron Automation and Safety meets all these critical substitution criteria, making it a direct functional equivalent for the obsolete HC1-DC6V-D-F.

Parameter Comparison

Engineering Selection Recommendations

The G2R-1-SD DC6(S) is the appropriate substitute for the obsolete HC1-DC6V-D-F based on the following factors:

• Product Status: The HC1-DC6V-D-F is obsolete, while the G2R-1-SD DC6(S) is active and currently available in production quantities
• Functional Equivalence: Both relays share identical coil voltage, contact form, current rating, and mounting configuration
• Compliance: The G2R-1-SD DC6(S) carries ROHS3 compliance and REACH status, meeting current regulatory requirements for new designs and replacements
• Availability: The G2R-1-SD DC6(S) has confirmed inventory of 785 pieces in stock, ensuring supply continuity

The G2R-1-SD DC6(S) exhibits superior electrical performance characteristics, including lower coil current (87 mA vs. 150 mA), higher switching voltage capability (440VAC vs. 250VAC), and faster operate time (15 ms vs. 20 ms), making it a direct drop-in replacement with enhanced specifications.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-SD DC6(S) directly replace the HC1-DC6V-D-F in existing applications?

A: Yes. Both relays are socketable with identical plug-in termination, 6VDC coil voltage, SPDT contact configuration, and 10A current rating. The G2R-1-SD DC6(S) can be inserted into existing HC1-DC6V-D-F relay sockets without modification.

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

A: The primary differences are coil current (87 mA vs. 150 mA), coil resistance (69 Ohms vs. 40 Ohms), switching voltage capability (440VAC vs. 250VAC), and operate time (15 ms vs. 20 ms). The G2R-1-SD DC6(S) offers improved performance across these parameters.

Q: Does the lower coil current of the G2R-1-SD DC6(S) affect compatibility?

A: No. Lower coil current is advantageous, reducing power consumption and heat generation. The must-operate voltage of 4.2 VDC for the G2R-1-SD DC6(S) is lower than the HC1-DC6V-D-F requirement of 4.8 VDC, ensuring reliable operation across the same voltage range.

Q: Are there packaging differences between these relays?

A: The HC1-DC6V-D-F is specified with standard packaging, while the G2R-1-SD DC6(S) is supplied in bulk packaging. Both maintain identical socketable form factors and plug-in termination styles.

Q: What is the operating temperature range difference?

A: The HC1-DC6V-D-F operates from -50°C to 70°C, while the G2R-1-SD DC6(S) operates from -40°C to 70°C. For applications requiring operation below -40°C, the original HC1-DC6V-D-F specification must be maintained if available.

Q: Is the G2R-1-SD DC6(S) suitable for new designs?

A: Yes. The G2R-1-SD DC6(S) is an active product with ROHS3 compliance and REACH status, making it appropriate for new designs and long-term production applications.
