HC3-HL-AC48V-F Equivalent & Substitute Parts

Part Overview

The HC3-HL-AC48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 48VAC coil. This socketable relay is designed for industrial control applications requiring reliable switching of up to 7A at 250VAC maximum. 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

Substitution compatibility for the HC3-HL-AC48V-F is determined by the following critical parameters:

• Coil Voltage: Must be 48VAC to ensure direct compatibility with existing control circuits
• Contact Form: Must be 3PDT (3 Form C) to maintain identical switching functionality
• Mounting Type: Must be socketable to fit existing relay sockets
• Termination Style: Must support plug-in connection for direct replacement
• Must Operate/Release Voltages: Must match 38.4 VAC and 14.4 VAC respectively to ensure proper circuit operation
• Contact Rating: Minimum 7A at the specified switching voltage
• Coil Type: Must be non-latching to match operational behavior

The Weidmüller 8689970000 satisfies all critical substitution criteria, offering enhanced performance characteristics while maintaining functional compatibility.

Engineering Selection Recommendations

The Weidmüller 8689970000 is the qualified substitute for the obsolete HC3-HL-AC48V-F. Selection is based on the following engineering criteria:

Functional Compatibility: Both relays share identical coil voltage (48VAC), contact configuration (3PDT), mounting type (socketable), and termination style (plug-in). Operating and release voltage thresholds are identical, ensuring seamless integration into existing control circuits.

Performance Enhancement: The substitute provides superior contact rating (10A versus 7A) and higher maximum switching voltage (400VAC versus 250VAC), offering increased design margin for the same application space.

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

Compliance: The Weidmüller 8689970000 carries RoHS compliance and REACH unaffected status, meeting current regulatory requirements for industrial component procurement.

Operational Characteristics: The substitute exhibits faster switching times (15ms operate, 10ms release versus 20ms for both), which may provide improved system responsiveness in time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8689970000 directly replace the HC3-HL-AC48V-F in existing installations?

A: Yes. Both relays are socketable with identical plug-in termination, 48VAC coil voltage, 3PDT contact configuration, and matching operating/release voltage thresholds. Direct socket replacement is possible without circuit modification.

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

A: The Weidmüller substitute offers higher contact current rating (10A versus 7A), higher maximum switching voltage (400VAC versus 250VAC), lower coil current draw (21.3mA versus 25mA), and faster switching response times. Operating temperature range is also extended (-40°C to 70°C versus -50°C to 60°C).

Q: Are there any compatibility concerns with the different contact materials?

A: Both relays use cadmium-free contact materials suitable for industrial applications. The Panasonic uses silver alloy while the Weidmüller uses silver nickel. Both materials are compatible with standard industrial switching loads.

Q: Does the Weidmüller relay include additional features?

A: Yes. The 8689970000 includes a test button in addition to the lighted indicator found on the HC3-HL-AC48V-F, and offers quick-connect termination as an alternative to standard plug-in connection.

Q: What is the coil resistance of the substitute part?

A: The Weidmüller 8689970000 has a coil resistance of 777 Ohms, which is consistent with its 48VAC coil voltage and 21.3mA coil current specification.

Q: Is the substitute part RoHS compliant?

A: Yes. The Weidmüller 8689970000 is RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial component procurement.
