Key Parameters

Substitute Part Grouping Explanation

The ADW1109TW is a parametric equivalent to the ADW1109W. Substitution is valid based on the following matching criteria:

• Identical coil voltage (9VDC)
• Identical contact form (SPST-NO, 1 Form A)
• Identical contact rating (8 A)
• Identical switching voltage rating (250VAC - Max)
• Identical maximum switching load (2000VA)
• Identical mounting type (Through Hole)
• Identical coil resistance (405 Ohms)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical contact material (Silver Tin Oxide)
• Identical coil type (Latching, Single Coil)
• Identical termination style (PC Pin)
• Identical seal rating (Sealed - Flux Protection)
• Identical RoHS compliance status
• Identical approval agencies (CQC, cURus, VDE)

The ADW1109TW includes IEC Compliant feature designation, which represents an additional specification layer without altering core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ADW1109W and ADW1109TW are active production parts from Panasonic Electric Works with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: ADW1109W has 992 pieces in stock; ADW1109TW has 961 pieces in stock
• Certification requirements: Both parts carry CQC, cURus, and VDE approvals
• RoHS compliance: Both parts are RoHS compliant
• Feature requirements: ADW1109TW includes IEC Compliant designation

For applications requiring IEC compliance documentation, the ADW1109TW is the appropriate selection. For general applications without specific IEC requirements, either part is suitable based on availability.

Frequently Asked Questions (FAQ)
