Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASD3K40N-RC is determined by the following critical parameters:

• Circuit configuration (4PST-NO)
• Number of positions (3)
• Current ratings (10A AC / 8A DC minimum)
• Voltage ratings (110V AC / 24V DC minimum)
• Actuator type (Flat Key)
• Mounting type (Panel Mount)
• Termination style (Screw Terminal)
• Panel cutout dimensions (Circular 30.50mm Dia)
• Environmental rating (IP54)
• Operating temperature range (-25°C to 50°C)
• RoHS compliance (ROHS3)

The substitute part ASD3K40NU-RC is classified as an equivalent based on manufacturer designation and active product status within the IDEC keylock switch product line.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K40NU-RC is designated as the direct manufacturer equivalent for the obsolete ASD3K40N-RC. Both components share the same base product number (ASD3) and maintain identical RoHS3 compliance and MSL ratings.

Selection of ASD3K40NU-RC is supported by:

• Active product status ensuring ongoing availability and supply chain support
• Maintained ROHS3 compliance for regulatory requirements
• Identical moisture sensitivity classification (MSL 1)
• Manufacturer-confirmed equivalency designation

Frequently Asked Questions (FAQ)

Q: Can ASD3K40NU-RC directly replace ASD3K40N-RC in existing installations?

A: Yes. Both components are manufactured by IDEC with the same base product number (ASD3) and share equivalent compliance certifications (ROHS3, MSL 1). The ASD3K40NU-RC is the active production equivalent of the obsolete ASD3K40N-RC.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. ASD3K40N-RC is obsolete, while ASD3K40NU-RC is active production. Both maintain the same regulatory compliance profile.

Q: Are there packaging differences between these parts?

A: The ASD3K40N-RC packaging designation is not specified in available documentation. The ASD3K40NU-RC is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What parameters must remain constant when selecting a substitute?

A: Critical parameters include circuit configuration (4PST-NO), number of positions (3), current ratings (10A AC / 8A DC), voltage ratings (110V AC / 24V DC), actuator type (Flat Key), mounting type (Panel Mount), termination style (Screw Terminal), and panel cutout dimensions (Circular 30.50mm Dia).

Q: Is the ASD3K40NU-RC suitable for the same operating temperature range?

A: The ASD3K40N-RC operates from -25°C to 50°C. Confirm operating temperature specifications for ASD3K40NU-RC with IDEC technical documentation or your component supplier.
