Substitute Part Grouping Explanation

The ASLD39920DN-A-240V has been identified with one active equivalent part: ASLD3QM420DNUA. This substitution is valid based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by IDEC
• Product Category: Both are selector switches
• RoHS Compliance: Both meet ROHS3 Compliant standards
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both share the same tariff classification 8536.50.9025
• Illumination Voltage: Both operate at 240 VAC nominal
• Mounting Type: Both are panel-mounted configurations
• Termination Style: Both utilize spring terminal connections

The substitute part ASLD3QM420DNUA represents an active product within the IDEC TWND series, providing functional continuity for applications previously served by the obsolete ASLD39920DN-A-240V.

Parameter Comparison

Engineering Selection Recommendations

The ASLD3QM420DNUA is the designated active equivalent for the obsolete ASLD39920DN-A-240V. Selection of this substitute part is supported by:
