ARS10A03 Equivalent & Substitute Parts

Part Overview

The ARS10A03 is a non-latching RF relay manufactured by Panasonic Electric Works, designed for surface mount applications with gull wing termination. This SPDT (Single Pole Double Throw) relay operates at 3VDC with a contact rating of 500mA and is actively produced. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring different contact current ratings or operating specifications within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1462050-1 (TE Connectivity Potter & Brumfield Relays) qualifies as an equivalent based on the following critical parameters:

• Coil Voltage Match: Both parts operate at 3VDC
• Contact Form Match: Both are SPDT (1 Form C) configuration
• Mounting Compatibility: Both use surface mount with gull wing termination
• Coil Type Match: Both are non-latching relays
• Voltage Thresholds: Both share identical must operate (2.25 VDC) and must release (0.3 VDC) voltages
• Regulatory Compliance: Both are RoHS compliant

The primary difference is contact current rating: ARS10A03 is rated at 500mA, while 1462050-1 is rated at 2A. This makes 1462050-1 suitable for applications requiring higher contact current capacity while maintaining all other electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both ARS10A03 and 1462050-1 are active products with current manufacturing status and full RoHS compliance. Selection between these parts depends on application requirements:

Select ARS10A03 when:

• Contact current requirement is 500mA or less
• Tube packaging is preferred for lower-volume applications
• Operating temperature range of -40°C to 70°C is sufficient
• Coil current budget is not a constraint

Select 1462050-1 when:

• Contact current requirement exceeds 500mA up to 2A
• Higher switching voltage capability (250VAC/220VDC) is required
• Faster switching response is needed (5ms operate, 4ms release vs. 10ms/6ms)
• Extended operating temperature range (-55°C to 85°C) is necessary
• Tape & Reel packaging is required for high-volume production
• Lower coil power consumption (140mW vs. 200mW) is beneficial

Both parts maintain identical coil voltage (3VDC), contact form (SPDT), mounting type (surface mount), and termination style (gull wing), ensuring mechanical and electrical compatibility in circuit design.

Frequently Asked Questions (FAQ)

Q: Can 1462050-1 directly replace ARS10A03 in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both relays share identical coil voltage (3VDC), contact form (SPDT), mounting type (surface mount), and termination style (gull wing). The 1462050-1 has higher contact current rating (2A vs. 500mA) and faster switching times, making it suitable for the same applications. Verify that your circuit design does not depend on the specific coil current or power characteristics of the original part.

Q: What is the difference in contact current rating between these parts?

A: ARS10A03 is rated for 500mA maximum contact current, while 1462050-1 is rated for 2A. If your application requires switching currents above 500mA, 1462050-1 is the appropriate choice. If your application requires 500mA or less, either part is acceptable.

Q: Are there packaging differences I should consider?

A: Yes. ARS10A03 is supplied in Tube packaging, suitable for lower-volume or manual assembly applications. 1462050-1 is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly in high-volume production. Packaging choice may affect procurement, handling, and assembly processes.

Q: Do both relays meet the same regulatory standards?

A: Both parts are RoHS compliant. ARS10A03 is RoHS Compliant, and 1462050-1 is ROHS3 Compliant, indicating both meet current environmental regulations. Both carry ECCN EAR99 classification and HTSUS 8536.41.0020 tariff code.

Q: What are the operating temperature differences?

A: ARS10A03 operates from -40°C to 70°C, while 1462050-1 operates from -55°C to 85°C. If your application requires operation below -40°C or above 70°C, 1462050-1 provides extended temperature capability.

Q: How do switching times compare?

A: ARS10A03 has an operate time of 10ms and release time of 6ms. 1462050-1 has faster switching with operate time of 5ms and release time of 4ms. For time-critical applications, 1462050-1 provides faster response.
