Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADW1224W are identified based on strict electrical and mechanical parameter matching within the Panasonic Electric Works DW series. The substitution criteria are:

• Identical coil voltage (24VDC)
• Identical contact form (SPST-NO / 1 Form A)
• Identical contact rating (8 A)
• Identical switching voltage rating (250VAC - Max)
• Identical load switching capacity (2000VA)
• Identical mounting type (Through Hole)
• Identical termination style (PC Pin)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical coil type (Latching, Dual Coil)
• Identical contact material (Silver Tin Oxide)
• Identical coil resistance (1.44 kOhms)
• Identical timing characteristics (15 ms operate and release times)
• Identical must operate voltage (19.2 VDC)
• Identical seal rating (Sealed - Flux Protection)
• Identical coil insulation class (Class F)

The ADW1224TW meets all these criteria and is classified as a parametric equivalent. Variations in RoHS compliance status and feature designations do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the ADW1224W and ADW1224TW are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: ADW1224TW has 934 units in stock compared to 890 units for ADW1224W
• RoHS compliance requirements: ADW1224TW carries ROHS3 compliance designation, while ADW1224W carries RoHS compliance designation
• Regulatory certifications: Both parts hold CQC, cURus, and VDE approvals, meeting international standards for general purpose relay applications
• Feature designation: ADW1224TW is designated as IEC Compliant, providing additional standards alignment

Both parts are suitable for direct substitution in applications requiring 24VDC SPST-NO relays with 8A contact rating and 250VAC switching capability.

Frequently Asked Questions (FAQ)

Q: Can ADW1224TW be used as a direct replacement for ADW1224W?

A: Yes. The ADW1224TW is a parametric equivalent with identical electrical and mechanical specifications, including coil voltage, contact rating, switching voltage, mounting type, and all timing characteristics. Direct substitution is supported without circuit modification.

Q: What are the key differences between ADW1224W and ADW1224TW?

A: The parts are electrically and mechanically identical. Differences are limited to RoHS compliance designation (ROHS3 vs. RoHS) and feature designation (IEC Compliant for ADW1224TW). Both parts meet the same international approvals and certifications.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both parts use identical through-hole PC pin termination and are housed in the same DW series package. PCB layouts designed for either part are interchangeable.

Q: What is the operating voltage range for these relays?

A: The coil operates at 24VDC nominal. The must operate voltage is 19.2 VDC, establishing the minimum voltage threshold for reliable relay activation. Contact switching is rated for 250VAC maximum.

Q: Are these relays suitable for high-frequency switching applications?

A: These relays are general purpose relays with 15 ms operate and release times. They are designed for standard switching applications, not high-frequency or rapid-cycle applications.

Q: What environmental conditions do these relays support?

A: Both relays operate across -40°C to 85°C temperature range with sealed flux protection and Class F coil insulation. Moisture sensitivity level is 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
