ARE1024C90 Equivalent & Substitute Parts

Part Overview

The ARE1024C90 is a non-latching RF relay manufactured by Panasonic Electric Works, designed for 24VDC coil operation with SPDT (1 Form C) contact configuration and 500mA contact rating. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The relay operates across industrial temperature ranges (-40°C to 70°C) with gold-plated contacts and through-hole PCB mounting.

Substitute Part Grouping Explanation

Substitution of the ARE1024C90 is determined by strict equivalence across the following critical parameters:

Coil voltage specification (24VDC)
Coil current draw (8.3 mA)
Contact configuration (SPDT / 1 Form C)
Contact current rating (500 mA minimum)
Maximum switching voltage (30VDC or higher)
Voltage thresholds (Must Operate: 18VDC, Must Release: 2.4VDC)
Mounting and termination compatibility (Through Hole, PC Pin)
Operating temperature range (-40°C to 70°C)
Contact material specification (Gold Plating)

The ARS1424 meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

The ARS1424 is the direct functional equivalent for ARE1024C90 replacement applications. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: ARE1024C90 is obsolete while ARS1424 remains in active production, ensuring long-term availability and supply chain continuity.

The release time differential (5ms vs 6ms) represents a 1ms variance and does not impact functional compatibility for standard relay switching applications within the specified operating parameters. Both relays maintain identical coil characteristics, contact ratings, voltage thresholds, and thermal operating ranges.

For new designs or system upgrades, ARS1424 is the recommended selection due to active production status and equivalent performance specifications. For legacy system maintenance where ARE1024C90 components require replacement, ARS1424 provides direct substitution without circuit redesign or application revalidation.

Frequently Asked Questions (FAQ)

Q: Can ARS1424 be used as a direct replacement for ARE1024C90 in existing circuits?

A: Yes. The ARS1424 meets all electrical and mechanical specifications of the ARE1024C90. Both relays operate at 24VDC with identical coil current (8.3mA), contact configuration (SPDT), contact rating (500mA), and mounting characteristics (Through Hole, PC Pin). No circuit modifications are required.

Q: What is the significance of the 1ms difference in release time?

A: The ARE1024C90 specifies 5ms release time while ARS1424 specifies 6ms. This 1ms variance falls within normal relay tolerance ranges and does not affect functional performance in standard switching applications. Both relays meet the specified voltage thresholds and operate within the same temperature range.

Q: Why is ARE1024C90 listed as obsolete?

A: ARE1024C90 has been discontinued by Panasonic Electric Works. ARS1424 is the active production equivalent, ensuring continued availability for replacement and new applications.

Q: Are there packaging differences between these relays?

A: ARE1024C90 packaging is listed as standard through-hole configuration. ARS1424 is supplied in Tube packaging. Both use identical PC Pin termination and Through Hole mounting, ensuring mechanical compatibility on PCBs.

Q: Do both relays meet the same compliance standards?

A: ARE1024C90 is ROHS3 compliant. ARS1424 carries EAR99 ECCN classification and HTSUS code 8536.41.0020. Both relays operate within identical electrical and thermal specifications suitable for industrial applications.
