Key Parameters

Substitute Part Grouping Explanation

The ADW1124TW is identified as a parametric equivalent to the ADW1124W based on strict alignment of electrical and mechanical specifications. Both parts share identical values across all critical substitution parameters: contact form (SPST-NO), coil voltage (24VDC), contact rating (8A), switching voltage (250VAC maximum), maximum switching load (2000VA), mounting type (through hole), termination style (PC pin), operating temperature range (-40°C to 85°C), coil type (latching, single coil), contact material (Silver Tin Oxide), coil resistance (2.88 kOhms), coil current (8.3 mA), must operate voltage (19.2 VDC), operate time (15 ms), and release time (15 ms).

The substitution is valid within the DW series of Panasonic Electric Works relays. Both parts maintain sealed flux protection and Class F coil insulation. Compliance certifications (CQC, cURus, VDE) are consistent across both variants.

Parameter Comparison

Engineering Selection Recommendations

Both ADW1124W and ADW1124TW are active production parts from Panasonic Electric Works with full regulatory compliance. The ADW1124W carries RoHS Compliant status, while the ADW1124TW carries ROHS3 Compliant status, indicating enhanced environmental compliance in the substitute. Both parts maintain identical electrical performance characteristics and mechanical compatibility. Selection between these parts may be based on inventory availability (ADW1124W: 1157 pieces; ADW1124TW: 946 pieces) and specific compliance requirements of the application. The ADW1124TW includes IEC Compliant designation and REACH Unaffected status, providing additional regulatory documentation for applications requiring enhanced traceability.

Frequently Asked Questions (FAQ)

Q: Can ADW1124TW be used as a direct replacement for ADW1124W in existing circuit designs?

A: Yes. Both parts maintain identical electrical specifications including coil voltage (24VDC), contact rating (8A), switching voltage (250VAC maximum), and all timing parameters (15 ms operate and release times). Mechanical compatibility is confirmed through identical mounting type (through hole) and termination style (PC pin). No circuit modifications are required.

Q: What are the key parameters that define substitution eligibility for this relay?

A: Substitution is determined by matching: contact form (SPST-NO), coil voltage (24VDC), contact current rating (8A), switching voltage (250VAC), maximum switching load (2000VA), mounting type (through hole), termination style (PC pin), operating temperature range (-40°C to 85°C), coil type (latching, single coil), contact material (Silver Tin Oxide), and timing specifications (15 ms operate and release times).

Q: Are there differences in compliance certifications between ADW1124W and ADW1124TW?

A: Both parts carry CQC, cURus, and VDE approvals. The ADW1124TW additionally specifies IEC Compliance and REACH Unaffected status. The ADW1124W is RoHS Compliant, while ADW1124TW is ROHS3 Compliant. These differences represent enhanced regulatory documentation in the substitute part without affecting electrical or mechanical performance.

Q: What is the significance of the latching, single coil configuration?

A: The latching, single coil design means the relay maintains its contact state after the coil is de-energized until a reset signal is applied. This configuration is critical for applications requiring state retention without continuous power consumption. Both substitute parts maintain this identical functionality.

Q: How do the coil specifications compare between these parts?

A: Both parts have identical coil specifications: 24VDC coil voltage, 8.3 mA coil current, 2.88 kOhms coil resistance, 19.2 VDC must operate voltage, and Class F coil insulation. These parameters ensure identical drive circuit requirements and thermal performance.
