HC1-HP-DC100V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-DC100V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 100VDC coil. This through-hole mounted relay is rated for 10A at 250VAC maximum switching voltage and operates with a 11mA coil current. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-HP-DC100V-F is determined by the following critical parameters:

Contact Configuration & Rating: The substitute must maintain SPDT (1 Form C) contact form with a minimum current rating of 10A and maximum switching voltage of 250VAC to preserve circuit functionality.

Coil Specifications: The substitute coil voltage must operate within the system's 100VDC nominal supply. Acceptable substitutes operate at coil voltages between 100VDC and 110VDC, provided the must-operate and must-release voltage thresholds remain compatible with the control circuit.

Mounting & Termination: Through-hole mounting with PC pin termination is required for direct board-level replacement without mechanical redesign.

Environmental & Compliance: Operating temperature range, contact material composition (cadmium-free requirement), and moisture sensitivity classification must meet or exceed the original specification.

Relay Type & Coil Behavior: Non-latching coil type must be maintained to preserve switching behavior in the application circuit.

The Weidmüller 8869830000 qualifies as a substitute based on these criteria: it maintains SPDT contact form, exceeds the 10A current rating (16A), operates at 110VDC coil voltage (within acceptable tolerance of 100VDC), uses PC pin termination, and maintains through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 8869830000 is suitable as a substitute for the obsolete HC1-HP-DC100V-F based on the following engineering criteria:

Product Status & Availability: The Weidmüller component is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete Panasonic part.

Functional Compatibility: Both relays maintain identical SPDT contact configuration and PC pin termination, enabling direct board-level replacement without circuit redesign. The Weidmüller part exceeds the original 10A current rating at 16A, providing additional margin for the application.

Coil Voltage Compatibility: The 110VDC coil voltage of the Weidmüller relay operates within acceptable tolerance of the original 100VDC specification. The must-operate voltage (77VDC) and must-release voltage (11VDC) remain compatible with standard 100VDC control circuits.

Compliance & Environmental Performance: The Weidmüller component is RoHS compliant and maintains MSL 1 (Unlimited) moisture sensitivity rating. Both parts operate across overlapping temperature ranges, with the Weidmüller rated to -40°C (compared to -50°C for the original).

Performance Characteristics: The Weidmüller relay demonstrates faster switching response (8ms operate, 6ms release versus 20ms for both parameters on the original), which may improve system responsiveness without introducing compatibility issues in non-time-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8869830000 directly replace the HC1-HP-DC100V-F without PCB modifications?

A: Yes. Both relays feature identical through-hole PC pin termination and SPDT contact configuration, enabling direct socket replacement on the PCB without mechanical or electrical redesign.

Q: What is the significance of the 10VDC coil voltage difference (100VDC vs. 110VDC)?

A: The 10VDC difference is within acceptable operating tolerance for relay substitution. The Weidmüller relay's must-operate voltage of 77VDC ensures reliable activation in standard 100VDC control circuits. The 1VDC difference in must-release voltage (10VDC vs. 11VDC) is negligible for circuit operation.

Q: Does the lower coil current of the Weidmüller relay (4.1mA vs. 11mA) affect circuit design?

A: The lower coil current reduces power consumption and heat generation in the control circuit, which is advantageous. No circuit modifications are required; the control circuit will operate with reduced current draw.

Q: Are there temperature range limitations when substituting?

A: The Weidmüller relay operates from -40°C to 70°C, compared to -50°C to 70°C for the original. If the application requires operation below -40°C, the Weidmüller substitute is not suitable. For standard industrial temperature ranges, both parts are equivalent.

Q: What is the impact of the faster switching times (8ms/6ms vs. 20ms/20ms)?

A: The Weidmüller relay switches faster, which improves response time in control circuits. This does not create compatibility issues in applications designed for the original 20ms switching times, as faster response is generally beneficial. Applications with specific timing requirements should verify that faster switching does not introduce unintended behavior.

Q: Is the contact material difference (Silver Alloy vs. Silver Nickel) significant?

A: Both contact materials are suitable for general-purpose relay applications at 250VAC maximum switching voltage. Silver Nickel (AgNi) offers comparable electrical performance and reliability. The cadmium-free requirement of the original is maintained by the Weidmüller component.

Q: What is the advantage of RoHS compliance in the Weidmüller part?

A: RoHS compliance ensures the component meets current environmental and regulatory standards for electronic equipment, particularly for applications subject to EU regulations or customer requirements. The original Panasonic part's RoHS status is not specified.

Q: Can the higher current rating (16A vs. 10A) of the Weidmüller relay cause issues?

A: No. A higher current rating provides additional safety margin and does not negatively affect circuit operation. The relay will handle the original 10A load with improved reliability and reduced contact wear.
