NDIR01H DIP Switch SPST Equivalent & Substitute Parts

Part Overview

The NDIR01H is a single-position DIP switch manufactured by APEM Inc., designed for through-hole mounting applications requiring low-current switching at 24VDC. This SPST (Single Pole Single Throw) switch features a slide actuator with a current rating of 25mA and operates across a temperature range of -20°C to 85°C. The part is currently active in production and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are met, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDIR01H 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 to 85°C)
• Contact finish (Gold)
• Mechanical and electrical life (2,000 Cycles)

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

Parameter Comparison

Engineering Selection Recommendations

Both the NDIR01H and KAE01LAGT are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on supply availability and inventory position rather than electrical or functional differences. The KAE01LAGT currently maintains higher inventory levels (14,212 pcs vs. 743 pcs), making it suitable for applications where supply continuity is a priority. Both parts carry identical certifications (ECCN: EAR99, HTSUS: 8536.50.9065) and meet the same regulatory requirements. Physical dimension variations are within acceptable tolerances for standard through-hole PCB applications with 0.100" pitch spacing.

Frequently Asked Questions (FAQ)

Q: Can KAE01LAGT be used as a direct replacement for NDIR01H on existing PCBs?

A: Yes. Both parts share identical electrical specifications, pitch spacing (0.100"), and PC pin termination. The minor differences in height above board (0.173" vs. 0.169") and length (0.137" vs. 0.141") do not affect PCB compatibility or circuit functionality.

Q: Are there differences in actuator operation between these parts?

A: Both use slide-type actuators. The NDIR01H features a flush/recessed actuator level, while the KAE01LAGT has a raised actuator level. This difference affects only the physical feel and accessibility of the switch; electrical operation and switching characteristics remain identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both NDIR01H and KAE01LAGT are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). They share identical ECCN and HTSUS classifications.

Q: What is the mechanical life expectancy for these switches?

A: Both parts are rated for 2,000 mechanical cycles and 2,000 electrical cycles under specified operating conditions (-20°C to 85°C).

Q: Are there packaging differences between these parts?

A: Both parts are supplied in tube packaging. Inventory availability differs, with KAE01LAGT currently in higher stock.
