ARE1012 Equivalent & Substitute Parts Reference

Part Overview

The ARE1012 is a radio frequency (RF) single-pole double-throw (SPDT) relay manufactured by Panasonic Electric Works, designed for 500 mA switching applications at 12 VDC. This component features non-latching operation with gold-plated contacts and through-hole PC pin termination. The ARE1012 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ARE1012 is determined by strict equivalence across the following critical parameters:

• Contact form configuration: SPDT (1 Form C)
• Contact current rating: 500 mA
• Coil voltage: 12 VDC
• Coil current: 16.7 mA
• Switching voltage maximum: 30 VDC
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -40°C to 70°C
• Contact material: Gold Plating
• Coil resistance: 720 Ohms

The ARS1412 meets all these critical parameters and qualifies as a direct functional equivalent. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications with only minor operational timing differences.

Parameter Comparison

Engineering Selection Recommendations

The ARS1412 is the qualified substitute for the obsolete ARE1012. Selection is based on the following factors:

• All critical electrical parameters match exactly between the two components
• The ARS1412 maintains active product status, ensuring ongoing availability and supply chain continuity
• Both components meet RoHS compliance requirements; the ARS1412 carries ROHS3 certification, representing current compliance standards
• Release time differs by 1 millisecond (5 ms vs. 6 ms), which remains within acceptable operational tolerance for most RF switching applications
• Packaging format differs (ARE1012 uses standard packaging; ARS1412 uses tube packaging), but this does not affect electrical or mechanical compatibility
• Both components are manufactured by the same supplier, ensuring consistent quality and reliability standards

Frequently Asked Questions (FAQ)

Q: Can the ARS1412 directly replace the ARE1012 in existing designs?

A: Yes. The ARS1412 meets all critical electrical and mechanical specifications of the ARE1012. Both components feature identical contact form, current rating, coil voltage, operating temperature range, and termination style. The 1 millisecond difference in release time does not affect functional compatibility in standard RF switching applications.

Q: What is the significance of the product status difference?

A: The ARE1012 is classified as obsolete, meaning it is no longer manufactured and existing inventory will eventually deplete. The ARS1412 maintains active product status, ensuring reliable long-term availability for new designs and system replacements.

Q: Does the packaging difference affect compatibility?

A: No. The ARE1012 uses standard packaging while the ARS1412 uses tube packaging. This difference applies only to order quantity and handling; it does not affect the electrical performance or mechanical fit of the component within the circuit.

Q: Are both components RoHS compliant?

A: Yes. The ARE1012 is RoHS Compliant. The ARS1412 is ROHS3 Compliant, which represents the current RoHS certification standard. Both meet environmental compliance requirements for electronic components.

Q: What parameters must match for substitution to be valid?

A: Contact form (SPDT), contact current rating (500 mA), coil voltage (12 VDC), coil current (16.7 mA), switching voltage (30 VDC max), mounting type (through hole), termination style (PC pin), operating temperature range (-40°C to 70°C), contact material (gold plating), and coil resistance (720 Ohms) must all be identical or equivalent.
