HC2-L-DC100V-D-F Equivalent & Substitute Parts

Part Overview

The HC2-L-DC100V-D-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 100VDC coil. This socketable, 8-pin relay is designed for applications requiring dual-pole, dual-throw switching at 7A contact rating. 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 of the HC2-L-DC100V-D-F is determined by the following critical parameters:

Contact Form Requirement: DPDT (2 Form C) configuration is mandatory for functional equivalence.

Coil Voltage Compatibility: The substitute must operate within the system's 100VDC nominal supply. The MY2N-D2 DC100/110 (S) operates at 110VDC, which falls within acceptable tolerance for DC relay applications where the must-operate and must-release voltages remain compatible.

Current Rating: The HC2-L-DC100V-D-F carries 7A at contact rating. The substitute MY2N-D2 DC100/110 (S) is rated at 5A. This represents a reduction in current capacity and must be evaluated against actual circuit requirements.

Mounting and Termination: Both parts feature socketable mounting with plug-in termination, ensuring mechanical and electrical compatibility in existing relay sockets.

Switching Voltage: Both parts support 250VAC maximum switching voltage, meeting standard AC switching requirements.

Operational Characteristics: Must-operate and must-release voltages, operate time, and release time are comparable between the two parts, ensuring similar response behavior in control circuits.

Parameter Comparison

Engineering Selection Recommendations

The MY2N-D2 DC100/110 (S) is an active, in-stock substitute for the obsolete HC2-L-DC100V-D-F. Both relays share identical contact form (DPDT), mounting configuration (socketable), and termination style (plug-in), ensuring direct mechanical and electrical compatibility in existing relay sockets.

The substitute operates at 110VDC coil voltage versus the original 100VDC specification. This 10V differential is within acceptable tolerance for DC relay applications, as both parts maintain compatible must-operate (80VDC vs. 88VDC) and must-release (10VDC vs. 11VDC) voltage thresholds.

The primary design consideration is the contact current rating reduction from 7A to 5A. Circuit applications requiring current switching above 5A cannot use this substitute without exceeding the contact rating specification.

The MY2N-D2 DC100/110 (S) carries RoHS compliance certification, providing environmental and regulatory advantages over the original part. Both relays feature identical coil type (non-latching), operate/release times (20 ms each), and include diode and lighted indicator features.

Frequently Asked Questions (FAQ)

Q: Can the MY2N-D2 DC100/110 (S) directly replace the HC2-L-DC100V-D-F in existing applications?

A: Direct mechanical and electrical replacement is possible due to identical socketable mounting, plug-in termination, and DPDT contact configuration. However, the 2A reduction in contact current rating (from 7A to 5A) must be verified against actual circuit requirements. If the application switches currents exceeding 5A, this substitute is not suitable.

Q: What is the significance of the 10VDC coil voltage difference?

A: The HC2-L-DC100V-D-F operates at 100VDC nominal, while the MY2N-D2 DC100/110 (S) operates at 110VDC. This difference is acceptable in DC relay applications because both parts maintain compatible must-operate and must-release voltage specifications. The substitute will function reliably within the specified voltage range of the original circuit.

Q: Are the operating characteristics identical between the two relays?

A: Both relays share identical operate time (20 ms) and release time (20 ms), ensuring equivalent switching response. Coil current is nearly identical (10 mA vs. 9 mA), and both feature non-latching coil type with diode and lighted indicator features.

Q: What is the impact of the contact material difference?

A: The HC2-L-DC100V-D-F uses silver alloy with cadmium-free and gold plating, while the MY2N-D2 DC100/110 (S) uses silver (Ag) contact material. Both materials are suitable for general-purpose switching applications. The substitute's silver contacts are standard for industrial relay applications.

Q: Does the MY2N-D2 DC100/110 (S) meet current regulatory requirements?

A: Yes. The substitute is RoHS compliant, meeting current environmental and regulatory standards. The original HC2-L-DC100V-D-F does not specify RoHS status. Both relays carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can the substitute operate in the same temperature range?

A: The MY2N-D2 DC100/110 (S) operates across -55°C to 70°C, which exceeds the original part's -50°C to 60°C range. The substitute provides extended low-temperature capability and higher maximum operating temperature.
