Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASX200A03 is based on the following critical parameters that must align for functional compatibility:

Mandatory Matching Parameters:

• Coil Voltage: 3VDC
• Contact Form: DPDT (2 Form C)
• Mounting Type: Surface Mount
• Termination Style: Gull Wing
• Coil Type: Non Latching

Allowable Parameter Variations:

• Contact Rating (Current): Substitute parts may exceed the 10mA minimum requirement, provided the application circuit can accommodate higher contact ratings
• Operating Temperature Range: Substitute parts with extended temperature ranges (-40°C ~ 85°C) are acceptable for applications within the original operating window
• Coil Current: Variations are acceptable if the driving circuit can supply the required current
• Coil Resistance: Variations are acceptable if circuit impedance matching is not critical
• Switching Voltage: Higher switching voltage ratings provide enhanced capability margins

The substitute parts V23079D1008B301 and V23079D2008B301 satisfy all mandatory matching parameters while providing improved electrical performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both V23079D1008B301 and V23079D2008B301 are suitable substitutes for the obsolete ASX200A03 based on the following engineering criteria:

Product Status and Availability: The substitute parts are classified as active products with confirmed inventory availability, ensuring long-term supply chain continuity compared to the obsolete ASX200A03.

Regulatory Compliance: Both substitute parts are RoHS Compliant, meeting current environmental and regulatory requirements. The ASX200A03 carries REACH Unaffected status, indicating no regulatory restriction on its use, but the RoHS Compliant substitutes provide enhanced compliance posture for new designs.

Electrical Performance: The substitute parts demonstrate improved electrical characteristics, including lower must-operate voltage (2.25VDC vs. 2.4VDC), faster switching times (4ms vs. 5ms), and extended operating temperature range (-40°C ~ 85°C vs. -40°C ~ 70°C). These improvements provide enhanced reliability margins.

Contact Rating Capability: The substitute parts provide 2A contact rating compared to the ASX200A03's 10mA rating. This increased capability is backward compatible with applications designed for the lower current rating.

Packaging Considerations: V23079D1008B301 is supplied in Tape & Reel (TR) packaging suitable for automated assembly. V23079D2008B301 is supplied in Cut Tape (CT) packaging suitable for manual or small-batch assembly. Selection depends on production volume and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can V23079D1008B301 and V23079D2008B301 be used interchangeably with ASX200A03?

A: Yes, both parts are functionally equivalent substitutes. The primary difference is packaging format: V23079D1008B301 uses Tape & Reel (TR) for high-volume automated assembly, while V23079D2008B301 uses Cut Tape (CT) for lower-volume or manual assembly. Electrical and mechanical specifications are identical between these two variants.

Q: What is the impact of the higher contact rating (2A vs. 10mA) on circuit design?

A: The 2A contact rating of the substitute parts exceeds the ASX200A03's 10mA specification. This provides enhanced current-carrying capability and is fully backward compatible with circuits designed for 10mA operation. No circuit redesign is required.

Q: Are there any coil current differences that affect the driving circuit?

A: The substitute parts require 46.7mA coil current compared to the ASX200A03's 16.7mA. The driving circuit must be capable of supplying this higher current. If the original circuit cannot provide 46.7mA, circuit modification is necessary.

Q: How do the switching time improvements affect system performance?

A: The substitute parts operate and release 1ms faster than the ASX200A03 (4ms vs. 5ms). This faster response time improves system switching performance and is fully compatible with applications designed for the original 5ms timing.

Q: What is the significance of the extended operating temperature range?

A: The substitute parts operate across -40°C ~ 85°C compared to the ASX200A03's -40°C ~ 70°C range. This extended range provides additional thermal margin for applications operating at elevated temperatures and is fully compatible with the original temperature specification.

Q: Does RoHS Compliance affect substitution decisions?

A: Both substitute parts are RoHS Compliant, meeting current environmental regulations. The ASX200A03 is REACH Unaffected, indicating no regulatory restriction. For new designs and long-term supply chain planning, RoHS Compliant substitutes are preferred to ensure regulatory alignment with current standards.
