HC2-DC48V-D-F Equivalent & Substitute Parts

Part Overview

The HC2-DC48V-D-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 48VDC coil. This relay is designed for applications requiring dual-pole, dual-throw switching at 7A contact rating with 250VAC maximum switching voltage. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-DC48V-D-F is determined by the following critical parameters:

• Coil Voltage: Must be 48VDC to maintain compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to preserve switching topology
• Contact Rating (Current): Minimum 7A to handle the original application load
• Switching Voltage: Must support 250VAC maximum to ensure safe operation in the intended application environment
• Coil Type: Must be Non Latching to match operational behavior
• Must Operate/Release Voltages: Must fall within acceptable ranges to ensure reliable actuation from the 48VDC supply
• Operating Temperature Range: Must encompass or exceed the original -50°C ~ 70°C range for environmental compatibility

The MKS2PN-D DC48 from Omron Automation and Safety meets these substitution criteria with enhanced specifications in contact rating (10A vs 7A) and additional features.

Parameter Comparison

Engineering Selection Recommendations

The MKS2PN-D DC48 is the qualified substitute for the HC2-DC48V-D-F based on the following factors:

Product Status: The HC2-DC48V-D-F is obsolete, while the MKS2PN-D DC48 is active and currently in production, ensuring long-term availability and supply chain continuity.

Compliance: The MKS2PN-D DC48 carries RoHS Compliant certification, meeting modern environmental and regulatory requirements. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Functional Compatibility: Both relays share identical coil voltage (48VDC), contact form (DPDT), and critical operating thresholds (Must Operate: 38.4 VDC). The MKS2PN-D DC48 provides higher contact rating (10A vs 7A), offering improved margin for the original 7A application.

Operational Differences: The MKS2PN-D DC48 exhibits slightly longer switching times (30ms operate, 40ms release vs 20ms each) and a narrower operating temperature range (-25°C ~ 60°C vs -50°C ~ 70°C). These differences must be evaluated against specific application requirements.

Mechanical Considerations: The MKS2PN-D DC48 features socketable mounting with 8-pin octal termination, providing installation flexibility compared to the original part's unspecified mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the MKS2PN-D DC48 directly replace the HC2-DC48V-D-F in existing applications?

A: The MKS2PN-D DC48 is functionally compatible for applications within its operating temperature range (-25°C ~ 60°C). If the original application requires operation below -25°C or above 60°C, environmental compatibility must be confirmed. The socketable mounting of the MKS2PN-D DC48 may require mechanical redesign if the original circuit board was designed for a different mounting style.

Q: What are the key differences in electrical performance?

A: The MKS2PN-D DC48 has higher contact rating (10A vs 7A), lower coil resistance (1.71 kOhms vs 2.6 kOhms), and higher coil current draw (28.1 mA vs 18.5 mA). Switching times are longer (30ms/40ms vs 20ms/20ms). These differences are within acceptable ranges for general purpose relay applications but must be validated for time-critical switching requirements.

Q: Are there packaging or termination compatibility issues?

A: The MKS2PN-D DC48 uses 8-pin octal plug-in termination, while the HC2-DC48V-D-F termination style is unspecified. If the original application uses a different termination method, mechanical adaptation or socket compatibility must be confirmed before substitution.

Q: Does the MKS2PN-D DC48 meet current regulatory requirements?

A: Yes. The MKS2PN-D DC48 is RoHS Compliant and carries active product status, meeting current environmental and regulatory standards. The HC2-DC48V-D-F is obsolete and does not carry RoHS certification.

Q: What is the impact of the narrower operating temperature range?

A: The MKS2PN-D DC48 operates from -25°C ~ 60°C, compared to the original -50°C ~ 70°C range. Applications requiring operation outside this range require alternative substitutes or the original part if still available.
