ARE1003 Equivalent & Substitute Parts Reference

Part Overview

The ARE1003 is a non-latching RF relay manufactured by Panasonic Electric Works, designed for 3VDC coil operation with SPDT contact configuration and 500mA switching capacity. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The ARE1003 operates across industrial temperature ranges (-40°C to 70°C) with gold-plated contacts suitable for reliable switching in RF applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARE1003 is determined by strict equivalence across the following critical parameters: coil voltage (3VDC), coil current (66.7 mA), contact form (SPDT), contact rating (500 mA), switching voltage (30VDC maximum), must-operate and must-release voltage thresholds, coil power (200mW), coil resistance (45 Ohms), operating temperature range (-40°C to 70°C), and contact material (gold plating).

Two substitute parts meet these core electrical requirements: ARS1403 and ARS14Y03. Both are manufactured by Panasonic Electric Works and maintain identical electrical performance specifications. The primary distinction between substitutes lies in packaging format and mounting technology. ARS1403 retains through-hole PC pin termination matching the original ARE1003 footprint. ARS14Y03 transitions to surface-mount gull-wing termination, requiring PCB layout modification but offering space efficiency benefits.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct PCB footprint compatibility without layout modification, ARS1403 is the appropriate selection. This part maintains through-hole PC pin termination identical to the ARE1003 while offering active product status and assured supply availability (1156 pcs in stock).

For new designs or PCB redesigns where space optimization is prioritized, ARS14Y03 provides surface-mount gull-wing termination with enhanced compliance documentation (ROHS3 Compliant, REACH Unaffected). This variant requires PCB layout modification but delivers equivalent electrical performance with modern manufacturing standards.

Both substitutes deliver identical electrical operation across all critical parameters. Selection between ARS1403 and ARS14Y03 depends solely on mechanical integration requirements and PCB assembly process capabilities.

Frequently Asked Questions (FAQ)

Q: Can ARS1403 replace ARE1003 without PCB modification? A: Yes. ARS1403 maintains identical through-hole PC pin termination and all electrical specifications, enabling direct substitution on existing PCB layouts.

Q: What is the primary difference between ARS1403 and ARS14Y03? A: ARS1403 uses through-hole PC pin mounting; ARS14Y03 uses surface-mount gull-wing termination. Electrical performance is identical. PCB layout modification is required for ARS14Y03 implementation.

Q: Are both substitute parts currently available? A: Yes. ARS1403 has 1156 pcs in stock; ARS14Y03 has 720 pcs in stock, both listed as active products.

Q: Do the substitute parts meet RoHS compliance? A: ARS1403 compliance status is not specified in available documentation. ARS14Y03 is ROHS3 Compliant and REACH Unaffected.

Q: Is there any difference in switching performance between ARE1003 and the substitutes? A: ARS1403 and ARE1003 have identical operate and release times (10 ms and 5 ms respectively). ARS14Y03 has a release time of 6 ms, a 1 ms difference from the original specification.
