Substitute Part Grouping Explanation

Substitution of the ASX220A24 is determined by the following critical parameters that must align across candidate parts:

• Contact form configuration: DPDT (2 Form C) structure
• Coil voltage: 24VDC nominal operation
• Mounting technology: Surface Mount with Gull Wing termination
• Coil type: Latching, Dual Coil architecture
• Operating temperature envelope compatibility
• Coil resistance and current draw characteristics
• Must Operate Voltage threshold: minimum 19.2 VDC

The V23079E1205B301 satisfies these core substitution criteria through matching contact configuration, coil voltage, mounting type, termination style, and coil architecture. Both components operate within compatible voltage and current parameters for their respective application classes.

Parameter Comparison

Engineering Selection Recommendations

The V23079E1205B301 provides functional equivalence to the obsolete ASX220A24 based on matching core electrical and mechanical specifications. The substitute part is currently in active production status with full availability, addressing the obsolescence constraint of the original component.

The V23079E1205B301 demonstrates superior operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) and faster switching response (4 ms versus 5 ms for both operate and release times). The substitute exhibits higher contact current rating (2 A versus 10 mA), which provides additional margin for applications within the original design envelope.

Coil resistance values are closely matched (4.11 kOhms versus 3.84 kOhms), and coil current draw is comparable (5.8 mA versus 6.3 mA), ensuring compatible power supply and control circuit integration. Must Operate Voltage thresholds are aligned (18 VDC versus 19.2 VDC), confirming reliable operation across the specified voltage range.

The V23079E1205B301 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Both components share EAR99 ECCN classification and identical HTSUS coding.

Frequently Asked Questions (FAQ)

Q: Can the V23079E1205B301 directly replace the ASX220A24 in existing designs?

A: Yes. Both components share identical contact form (DPDT), coil voltage (24VDC), mounting type (Surface Mount), termination style (Gull Wing), and coil architecture (Latching, Dual Coil). Coil resistance and current draw are within compatible ranges. The substitute operates across a wider temperature range and exhibits faster switching times.

Q: What is the primary difference between these relay types?

A: The ASX220A24 is classified as a telecom relay with 10 mA contact rating, while the V23079E1205B301 is a general-purpose relay with 2 A contact rating. The substitute provides significantly higher current-switching capability while maintaining compatibility with the original 24VDC coil voltage and DPDT switching configuration.

Q: Are there packaging differences between these parts?

A: The ASX220A24 uses standard packaging, while the V23079E1205B301 is supplied in Cut Tape (CT) format. Both employ Gull Wing surface mount termination. Verify tape specifications and reel configurations against procurement requirements.

Q: How do the switching times compare?

A: The V23079E1205B301 operates faster, with 4 ms operate and release times compared to 5 ms for the ASX220A24. This represents a 20% improvement in switching response, which may benefit applications requiring faster state transitions.

Q: What compliance certifications apply to the substitute part?

A: The V23079E1205B301 is ROHS3 compliant and REACH Unaffected. Both components carry EAR99 ECCN classification. Verify compliance requirements against specific application and regional standards.
