HC1-HP-DC48V-F Equivalent & Substitute Parts

Part Overview

The HC1-HP-DC48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring SPDT (1 Form C) contact configuration with 48VDC coil voltage and 10A contact rating. This through-hole mounted relay is designed for industrial control applications requiring reliable switching at 250VAC maximum. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC1-HP-DC48V-F is determined by the following critical parameters:

Primary Matching Criteria:

• Coil voltage: 48VDC (exact match required)
• Contact form: SPDT (1 Form C) configuration
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching

Secondary Compatibility Criteria:

• Contact rating current: Equal to or greater than 10A
• Switching voltage: Equal to or greater than 250VAC
• Operating temperature range: Must encompass or exceed -50°C ~ 70°C
• Relay type: General purpose

The substitute part 8869820000 (Weidmüller RCI series) meets all primary matching criteria and exceeds secondary compatibility requirements with higher contact current rating (16A) and faster switching times.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 8869820000 relay serves as a direct functional substitute for the obsolete HC1-HP-DC48V-F. Both relays share identical coil voltage, contact configuration, and switching voltage specifications, with the Weidmüller part offering superior performance characteristics including higher contact current capacity (16A vs 10A), lower coil current draw (8.7mA vs 18.5mA), and faster switching response times (8ms operate, 6ms release vs 20ms each).

The Weidmüller part is currently in active production status with RoHS compliance certification, providing long-term availability and regulatory alignment for new designs and system upgrades. The lower minimum operating voltage (33.6VDC vs 38.4VDC) provides improved operational margin in applications with voltage fluctuation.

The operating temperature range of the Weidmüller part (-40°C ~ 70°C) is narrower at the lower end by 10°C compared to the original part. Applications requiring operation below -40°C must retain the original HC1-HP-DC48V-F specification or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 8869820000 directly replace the HC1-HP-DC48V-F in existing circuits?

A: Yes. Both relays feature identical 48VDC coil voltage, SPDT contact configuration, 250VAC switching voltage, through-hole mounting, and PC pin termination. The Weidmüller part's higher current rating (16A) and faster switching times represent performance improvements for standard applications.

Q: What is the impact of different coil current specifications (18.5mA vs 8.7mA)?

A: The Weidmüller relay requires significantly lower coil current, reducing power consumption and heat generation in the control circuit. Existing driver circuits designed for the original 18.5mA specification will operate the Weidmüller relay without modification, as the lower current draw represents a less demanding load.

Q: Are there temperature range limitations when substituting?

A: The Weidmüller part operates from -40°C to 70°C, compared to the original -50°C to 70°C range. Applications requiring operation below -40°C cannot use this substitute without additional thermal management or alternative component selection.

Q: How do the switching time differences affect system performance?

A: The Weidmüller relay operates approximately 2.5 times faster (8ms vs 20ms operate time, 6ms vs 20ms release time). In applications with strict timing requirements, this faster response may require circuit validation to ensure compatibility with downstream logic and control systems.

Q: What compliance certifications apply to the substitute part?

A: The Weidmüller 8869820000 is RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial component procurement and system deployment.
