ARE1003C90 Equivalent & Substitute Parts Reference

Part Overview

The ARE1003C90 is a non-latching RF relay manufactured by Panasonic Electric Works, designed for 3VDC coil operation with SPDT (1 Form C) contact configuration and 500mA contact rating. This component is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing design support and procurement continuity. The relay features through-hole mounting with PC pin termination, gold-plated contacts, and operates across the -40°C to 70°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ARE1003C90 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 3VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 500 mA minimum
• Switching voltage: 30VDC maximum
• Must operate voltage: 2.25 VDC
• Must release voltage: 0.3 VDC
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -40°C ~ 70°C
• Contact material: Gold Plating

The ARS1403 meets all mandatory substitution criteria. Minor variations in release time (6ms vs 5ms) remain within acceptable operational tolerances for relay switching applications and do not disqualify this component as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ARS1403 is the qualified substitute for the obsolete ARE1003C90. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications across all critical parameters. The ARS1403 maintains active product status, ensuring ongoing availability and supply chain continuity. Both components comply with ROHS3 standards, supporting environmental and regulatory requirements. The 1ms difference in release time (ARS1403: 6ms vs ARE1003C90: 5ms) does not impact functional compatibility in standard relay switching applications. Direct PCB footprint compatibility is maintained through identical through-hole PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can the ARS1403 be used as a direct replacement for the ARE1003C90?

A: Yes. The ARS1403 meets all mandatory electrical and mechanical specifications of the ARE1003C90, including coil voltage, contact configuration, current rating, switching voltage, operating temperature range, and mounting style. Both components feature identical PC pin through-hole termination and gold-plated contacts.

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

A: The ARS1403 has a 6ms release time compared to the ARE1003C90's 5ms release time. This 1ms variance is within acceptable operational tolerance for relay switching applications and does not affect functional compatibility or circuit performance in standard configurations.

Q: Are there any compliance or certification differences between these parts?

A: Both the ARE1003C90 and ARS1403 comply with ROHS3 standards. The primary difference is product status: the ARE1003C90 is obsolete, while the ARS1403 is active. The active status of the ARS1403 ensures continued manufacturing and supply availability.

Q: Will the ARS1403 fit the existing PCB layout designed for the ARE1003C90?

A: Yes. Both components use identical through-hole PC pin termination and are designed for the same mounting type. No PCB layout modifications are required for substitution.

Q: What is the coil power consumption for the ARS1403?

A: The ARS1403 has a coil power rating of 200mW, identical to the ARE1003C90, with a coil resistance of 45 Ohms at 3VDC operation.
