ADW1109HTW Equivalent & Substitute Parts

Part Overview

The ADW1109HTW is a general purpose relay manufactured by Panasonic Electric Works, designed for SPST-NO (1 Form A) switching applications with a 9VDC coil. This through-hole mounted relay is rated for 16A at 277VAC maximum switching voltage, delivering 4432VA maximum load switching capacity. The part is currently active in production with 808 units in stock. Alternative models may be required due to inventory constraints, supply chain considerations, or specific application requirements within the same electrical and mechanical parameter range.

Key Parameters

Substitute Part Grouping Explanation

The ADW1109HLW qualifies as a parametric equivalent to the ADW1109HTW based on strict alignment of critical electrical and mechanical parameters. Both parts share identical specifications across all functional switching characteristics: 9VDC coil voltage, SPST-NO contact form, 16A contact rating, 277VAC maximum switching voltage, 4432VA maximum load switching, latching single coil configuration, through-hole mounting with PC pin termination, and -40°C to 85°C operating temperature range. Both parts are manufactured by Panasonic Electric Works within the DW series, utilize Silver Tin Oxide contact material, maintain 405 Ohms coil resistance, and carry equivalent regulatory approvals (CQC, cURus, VDE). The substitution is valid based on these matching electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ADW1109HTW and ADW1109HLW are active production parts with full regulatory compliance. Selection between these parts should be based on inventory availability and supply chain requirements. The ADW1109HLW currently maintains higher stock levels at 978 units compared to 808 units for the ADW1109HTW. Both parts carry identical electrical performance specifications, mechanical compatibility, and regulatory certifications (CQC, cURus, VDE). Either part is suitable for direct substitution in applications requiring 9VDC SPST-NO relay functionality with 16A switching capacity at 277VAC maximum voltage.

Frequently Asked Questions (FAQ)

Q: Can ADW1109HLW be used as a direct replacement for ADW1109HTW?

A: Yes. Both parts are manufactured by Panasonic Electric Works within the DW series and share identical electrical and mechanical specifications. All critical parameters including coil voltage, contact form, current rating, switching voltage, mounting type, and termination style are equivalent.

Q: Are there differences in regulatory compliance between these parts?

A: Both parts carry the same regulatory approvals from CQC, cURus, and VDE. The ADW1109HTW is ROHS3 Compliant while the ADW1109HLW is RoHS Compliant. Both meet environmental and safety standards for their respective applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: coil voltage (9VDC), contact form (SPST-NO), contact rating (16A), switching voltage (277VAC max), load capacity (4432VA), mounting type (through hole), termination style (PC pin), coil type (latching single coil), operating temperature range (-40°C to 85°C), and contact material (Silver Tin Oxide).

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in tray packaging. The ADW1109HLW has higher current inventory availability at 978 units compared to 808 units for the ADW1109HTW. Packaging format and moisture sensitivity level (MSL 1 - Unlimited) are identical.

Q: Can these relays be used in applications requiring different coil voltages?

A: No. Both parts are specifically designed for 9VDC coil operation with a must-operate voltage of 7.2VDC. They are not suitable for applications requiring different coil voltages.
