ARE10A09 Equivalent & Substitute Parts Reference

Part Overview

The ARE10A09 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 9VDC coil voltage. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The part operates within a -40°C to 70°C temperature range with gold-plated contacts and gull wing termination suitable for automated assembly processes.

Key Parameters

Substitute Part Grouping Explanation

The ARS14A09 qualifies as a direct functional substitute for the ARE10A09 based on the following critical parameters:

Electrical Equivalence Criteria:

• Identical coil voltage specification (9VDC)
• Matching coil current draw (22.2 mA)
• Identical contact form configuration (SPDT)
• Matching contact current rating (500 mA)
• Identical switching voltage maximum (30VDC)
• Matching must-operate and must-release voltage thresholds (6.75 VDC / 0.9 VDC)
• Identical coil resistance (405 Ohms) and power consumption (200 mW)

Mechanical and Environmental Equivalence:

• Identical mounting type (Surface Mount)
• Identical termination style (Gull Wing)
• Matching operating temperature range (-40°C to 70°C)
• Identical contact material specification (Gold Plating)

Compliance Equivalence:

• Both RoHS Compliant
• Matching ECCN and HTSUS classifications

The ARS14A09 represents an active product from the same manufacturer, providing improved availability compared to the obsolete ARE10A09. Minor timing differences (6 ms release time versus 5 ms) fall within acceptable operational tolerances for relay substitution and do not affect functional compatibility in standard RF switching applications.

Parameter Comparison

Engineering Selection Recommendations

The ARS14A09 is the designated substitute for the obsolete ARE10A09. Selection of the ARS14A09 is supported by:

Product Status Consideration: The ARE10A09 is classified as obsolete, creating supply chain risk. The ARS14A09 maintains active product status with documented inventory availability (853 pcs), ensuring procurement reliability for new designs and system maintenance.

Compliance Alignment: Both parts maintain identical RoHS compliance status and matching ECCN/HTSUS classifications, eliminating regulatory substitution barriers.

Electrical and Mechanical Compatibility: All critical electrical parameters, mechanical mounting specifications, and environmental operating ranges are identical between the two parts. The 1 ms difference in release time (5 ms versus 6 ms) is within standard relay performance tolerances and does not impact functional compatibility in RF switching applications.

Packaging Consideration: The ARS14A09 is supplied in tube packaging, which may require process adjustment if the original ARE10A09 was specified in bulk form. Tube packaging is standard for active production components and is compatible with automated assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can the ARS14A09 be used as a direct replacement for the ARE10A09 in existing designs?

A: Yes. The ARS14A09 meets all electrical, mechanical, and environmental specifications of the ARE10A09. No circuit modifications or PCB layout changes are required. Both parts feature identical gull wing termination, surface mount configuration, and contact ratings.

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

A: The ARE10A09 specifies 5 ms release time while the ARS14A09 specifies 6 ms release time. This 1 ms difference is within standard relay performance variation and does not affect functional compatibility in RF switching applications. Applications with critical timing requirements below 1 ms precision should be evaluated against specific system performance data.

Q: Why is the ARE10A09 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The ARS14A09 represents the active equivalent from Panasonic Electric Works, ensuring continued availability and supply chain stability.

Q: Are there packaging differences between these parts?

A: Yes. The ARE10A09 is supplied in bulk packaging while the ARS14A09 is supplied in tube packaging. Tube packaging is standard for active production components and is compatible with automated assembly processes. Reel or tape packaging may be available upon request from the manufacturer.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the ARE10A09 and ARS14A09 are RoHS Compliant with matching ECCN (EAR99) and HTSUS (8536.41.0020) classifications.

Q: What is the coil power consumption for these relays?

A: Both parts consume 200 mW at 9VDC coil voltage with 22.2 mA coil current. The 405 Ohm coil resistance is identical between both parts.
