ARE13A03 Equivalent & Substitute Parts

Part Overview

The ARE13A03 is a surface mount RF relay manufactured by Panasonic Electric Works, configured as a single pole double throw (SPDT) contact form with 500 mA current rating and 3VDC coil voltage. This part operates in the non-latching mode with gold-plated contacts suitable for RF applications. The ARE13A03 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ARE13A03 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution validity are:

• Contact form configuration (SPDT)
• Contact current rating (500 mA minimum)
• Coil voltage (3VDC)
• Coil current draw (66.7 mA)
• Maximum switching voltage (30VDC)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Operating temperature range (-40°C to 70°C)
• Contact material (Gold Plating)

The identified substitutes ARS10A03 and ARS10Y03 maintain electrical equivalence across all critical parameters. Both parts are manufactured by Panasonic Electric Works and share identical contact ratings, coil specifications, and environmental operating conditions. The primary distinction between substitutes is product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both ARS10A03 and ARS10Y03 provide direct electrical and mechanical substitution for the obsolete ARE13A03. Selection between active alternatives is determined by compliance requirements and product availability.

ARS10A03 maintains RoHS compliance equivalent to the original part and is currently in active production status with 839 units available. This part is suitable for applications where standard RoHS certification is the compliance requirement.

ARS10Y03 offers ROHS3 compliance with REACH unaffected status, providing enhanced regulatory coverage for applications requiring stricter environmental standards. This variant maintains identical electrical performance and is available in significantly higher inventory (30,100 units), supporting higher-volume procurement requirements.

Both substitutes exhibit a 1 millisecond increase in release time (6 ms versus 5 ms) compared to the original ARE13A03. This parameter variance remains within typical relay performance tolerances for non-latching SPDT applications and does not impact functional equivalence for standard RF relay circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can ARS10A03 and ARS10Y03 be used interchangeably with ARE13A03?

A: Yes. Both parts maintain identical electrical specifications across contact form, current rating, coil voltage, switching voltage, and operating temperature range. The 1 millisecond difference in release time does not affect functional compatibility in standard applications.

Q: What is the difference between ARS10A03 and ARS10Y03?

A: The primary differences are compliance certifications and inventory availability. ARS10A03 carries RoHS compliance, while ARS10Y03 carries ROHS3 compliance with REACH unaffected status. ARS10Y03 has significantly higher stock availability (30,100 units versus 839 units).

Q: Why is the ARE13A03 marked as obsolete?

A: The ARE13A03 has been discontinued by Panasonic Electric Works. The active ARS series variants (ARS10A03 and ARS10Y03) represent the current production alternatives with equivalent performance specifications.

Q: Are the gull wing terminations compatible with existing PCB layouts designed for ARE13A03?

A: Yes. Both substitute parts maintain identical surface mount gull wing termination style, ensuring mechanical and electrical compatibility with PCB designs specified for ARE13A03.

Q: What compliance certifications apply to each substitute?

A: ARS10A03 is RoHS Compliant. ARS10Y03 is ROHS3 Compliant with REACH Unaffected status. Both parts carry EAR99 ECCN classification and 8536.41.0020 HTSUS code.
