Substitute Part Grouping Explanation

The ASD31K20NU is identified as a direct substitute for the ASD31K20N based on the following substitution criteria:

Matching Parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Base Product Number: ASD31 (same product family)
• Circuit Configuration: DPST-NO (identical electrical circuit)
• Number of Positions: 3 (identical functional positions)
• Actuator Type: Flat Key (identical mechanical interface)
• Mounting Type: Panel Mount (identical installation method)
• Termination Style: Screw Terminal (identical connection method)
• Panel Cutout Dimensions: Circular - 30.50mm Dia (identical mechanical fit)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (equivalent handling requirements)

The ASD31K20NU maintains all critical electrical and mechanical parameters required for direct substitution in applications previously using the ASD31K20N.

Parameter Comparison

Engineering Selection Recommendations

The ASD31K20NU is the appropriate substitute for the obsolete ASD31K20N. Both components are manufactured by IDEC and maintain identical electrical circuit configurations, mechanical interfaces, and environmental compliance certifications. The ASD31K20NU carries active product status, ensuring ongoing availability and supply chain continuity. Both parts meet ROHS3 compliance requirements and share equivalent moisture sensitivity classifications, making them suitable for equivalent application environments.

Frequently Asked Questions (FAQ)

Q: Can the ASD31K20NU directly replace the ASD31K20N in existing installations?

A: Yes. The ASD31K20NU maintains identical circuit configuration (DPST-NO), position count (3), actuator type (Flat Key), mounting method (Panel Mount), termination style (Screw Terminal), and panel cutout dimensions (30.50mm Dia). These parameters ensure mechanical and electrical compatibility in applications previously using the ASD31K20N.

Q: What is the primary difference between these two parts?

A: The ASD31K20N is classified as obsolete, while the ASD31K20NU maintains active product status. The ASD31K20NU is available in bulk packaging, whereas the ASD31K20N packaging specification is not defined. Both parts are ROHS3 compliant and functionally equivalent.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The ECCN classification differs due to product status designation, but this does not affect component functionality or application suitability.

Q: What parameters determine substitution eligibility for this product category?

A: For keylock switches, substitution eligibility is determined by: circuit configuration (DPST-NO), number of positions (3), actuator type (Flat Key), mounting type (Panel Mount), termination style (Screw Terminal), and panel cutout dimensions (30.50mm Dia). Matching these parameters ensures mechanical fit and electrical compatibility.
