NDIR01S Equivalent & Substitute Parts

Part Overview

The NDIR01S is a DIP slide switch manufactured by APEM Inc., designed for through-hole mounting applications requiring single-pole, single-throw (SPST) switching functionality. This component operates at 24VDC with a 25mA current rating and is classified as Active product status. Alternative equivalent parts may be required due to inventory availability, lead time considerations, or specific application requirements such as actuator profile or body material specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the NDIR01S is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (1)
• Current rating (25mA)
• Voltage rating (24VDC)
• Actuator type (Slide Standard)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Pitch spacing (0.100" / 2.54mm)
• Operating temperature range (-20°C ~ 85°C)
• Mechanical and electrical life (2,000 Cycles)
• Regulatory compliance (ROHS3, MSL 1)

The KAE01LAGT from E-Switch meets all substitution criteria. Minor variations in physical dimensions (height above board, length) and actuator level (Raised vs. Flush/Recessed) do not affect electrical functionality or PCB compatibility when pitch and termination style remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the NDIR01S and KAE01LAGT are Active product status components with identical regulatory compliance profiles (ROHS3, MSL 1, REACH Unaffected, EAR99 classification). Selection between these parts should be based on:

• Inventory availability and lead time requirements
• PCB layout constraints related to actuator profile (Flush/Recessed vs. Raised)
• Physical height tolerance specifications (NDIR01S: 0.173" vs. KAE01LAGT: 0.169")
• Preferred supplier and supply chain considerations

Both parts are electrically and mechanically interchangeable for applications requiring SPST DIP slide switches at 24VDC, 25mA with through-hole PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can KAE01LAGT replace NDIR01S in existing designs without PCB modification?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), termination style (PC Pin), and electrical specifications. Physical height differences (0.173" vs. 0.169") are within typical PCB clearance tolerances and do not require layout changes.

Q: What is the significance of the actuator level difference (Flush/Recessed vs. Raised)?

A: Actuator level affects the switch's profile above the PCB surface. Flush/Recessed actuators sit lower; Raised actuators extend higher. Selection depends on enclosure design and user interface requirements. Both configurations maintain identical electrical performance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both NDIR01S and KAE01LAGT carry identical regulatory certifications: ROHS3 Compliant, MSL 1 (Unlimited), REACH Unaffected, and EAR99 classification.

Q: What determines substitution eligibility for DIP slide switches?

A: Substitution requires matching circuit configuration (SPST), position count (1), current rating (25mA), voltage rating (24VDC), actuator type (Slide Standard), mounting method (Through Hole), termination style (PC Pin), and pitch spacing (0.100" / 2.54mm). Operating temperature range, mechanical/electrical life, and compliance status must also align.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts meet identical mechanical life (2,000 Cycles) and electrical life (2,000 Cycles) specifications. Selection should be based on application-specific reliability requirements and supplier qualification status.
