HC2-HL-AC48V-F Equivalent & Substitute Parts

Part Overview

The HC2-HL-AC48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 48VAC coil. This socketable relay is designed for industrial control applications requiring reliable switching of AC loads up to 250VAC at 7A. 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 of the HC2-HL-AC48V-F is determined by the following critical parameters that must match or exceed the original specification:

• Coil Voltage: Must be 48VAC to ensure direct compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to maintain identical switching functionality
• Mounting Type: Must be socketable to fit existing relay bases
• Termination Style: Must support plug-in connection for direct replacement
• Must Operate/Release Voltage: Must match 38.4 VAC / 14.4 VAC thresholds for proper circuit operation
• Coil Type: Must be non-latching for equivalent control behavior

The PT270548 qualifies as a substitute because it meets all critical parameters while offering enhanced electrical ratings (12A contact current vs. 7A, 400VAC switching vs. 250VAC) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The PT270548 is a direct functional substitute for the HC2-HL-AC48V-F based on matching coil voltage, contact configuration, and operating thresholds. The PT270548 offers the following advantages:

• Active Product Status: Currently manufactured and available, eliminating obsolescence concerns
• Enhanced Electrical Ratings: Higher contact current (12A vs. 7A) and switching voltage (400VAC vs. 250VAC) provide margin for existing applications
• RoHS3 Compliance: Meets current environmental regulations
• Extended Temperature Range: Operating range of -40°C ~ 70°C covers the original -50°C ~ 60°C specification
• Mechanical Indicator and Test Button: Additional features support field diagnostics

Both relays carry EAR99 ECCN classification and unlimited moisture sensitivity rating (MSL 1), indicating equivalent regulatory and environmental handling requirements.

Frequently Asked Questions (FAQ)

Q: Can PT270548 directly replace HC2-HL-AC48V-F in existing installations?

A: Yes. Both relays share identical coil voltage (48VAC), contact form (DPDT), mounting type (socketable), and operating thresholds (38.4 VAC must-operate, 14.4 VAC must-release). The PT270548 is mechanically and electrically compatible for direct substitution.

Q: What are the differences between these two relays?

A: The PT270548 has higher contact current rating (12A vs. 7A), higher maximum switching voltage (400VAC vs. 250VAC), extended operating temperature range (-40°C ~ 70°C vs. -50°C ~ 60°C), and includes mechanical indicator and test button features. Contact material differs: Silver Alloy Cadmium Free vs. Silver Nickel.

Q: Does the higher current rating of PT270548 affect compatibility?

A: No. Higher electrical ratings do not compromise compatibility. The PT270548 will operate identically in circuits designed for the HC2-HL-AC48V-F, as it meets or exceeds all specified parameters.

Q: Are there packaging differences?

A: The HC2-HL-AC48V-F is packaged as individual units, while PT270548 is supplied in bulk packaging. Both use identical plug-in termination for relay base mounting.

Q: What compliance certifications apply to both relays?

A: Both relays carry EAR99 ECCN classification. The PT270548 additionally holds RoHS3 compliance and REACH unaffected status, reflecting current environmental standards.
