ARE1312 RF SPDT Relay - Equivalent & Substitute Parts

Part Overview

The ARE1312 is a non-latching RF SPDT relay manufactured by Panasonic Electric Works, designed for 12VDC coil operation with 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 suitable for RF applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARE1312 is determined by strict equivalence across the following critical parameters:

• Coil voltage and current characteristics (12VDC, 16.7 mA)
• Contact configuration and rating (SPDT, 500 mA)
• Switching voltage specification (30VDC maximum)
• Voltage thresholds for operation and release (9 VDC must-operate, 1.2 VDC must-release)
• Operating temperature range (-40°C to 70°C)
• Physical mounting and termination compatibility (Through Hole, PC Pin)
• Contact material specification (Gold Plating)

The ARS1012 meets all these criteria, with the exception of release time (6 ms versus 5 ms for the ARE1312). This minor timing difference does not affect functional substitution in applications where the ARE1312 operates.

Parameter Comparison

Engineering Selection Recommendations

The ARS1012 serves as the direct functional equivalent for the obsolete ARE1312. Selection of the ARS1012 is supported by:

• Active product status, ensuring ongoing availability and supply chain continuity
• Full electrical parameter equivalence across all critical specifications
• Enhanced RoHS3 compliance status, meeting current regulatory requirements
• Identical mechanical and electrical interface characteristics
• Panasonic Electric Works manufacturing consistency

The 1 millisecond difference in release time (6 ms versus 5 ms) represents a negligible variance that does not impact substitution suitability for standard relay applications.

Frequently Asked Questions (FAQ)

Q: Can the ARS1012 directly replace the ARE1312 in existing designs?

A: Yes. The ARS1012 provides electrical and mechanical equivalence across all specified parameters. The minor release time difference (6 ms versus 5 ms) does not affect functional compatibility in standard applications.

Q: What is the primary reason for substitution?

A: The ARE1312 is classified as obsolete. The ARS1012 is an active product from the same manufacturer with identical electrical specifications, ensuring continued component availability.

Q: Are there packaging differences between these parts?

A: The ARE1312 uses standard packaging, while the ARS1012 is supplied in box packaging. Both maintain identical Through Hole PC Pin termination and mounting characteristics.

Q: Do both parts meet current compliance standards?

A: Yes. The ARE1312 is RoHS Compliant, and the ARS1012 is ROHS3 Compliant. Both parts carry EAR99 ECCN classification and share the same HTSUS code (8536.41.0020).

Q: Are there any operational differences in coil characteristics?

A: No. Both parts operate at 12VDC with 16.7 mA coil current, 200mW coil power, and 720 Ohms coil resistance. Voltage thresholds for operation and release are identical.

Q: What is the temperature operating range for both parts?

A: Both the ARE1312 and ARS1012 operate across -40°C to 70°C, supporting industrial and extended temperature applications.
