NDI01H DIP Switch SPST Equivalent & Substitute Parts

Part Overview

The NDI01H 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 gold-plated copper alloy contacts and is rated for 25mA at 24VDC. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to inventory availability, lead time constraints, or design flexibility across compatible product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDI01H is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be SPST
• Single position requirement
• Current rating of 25mA minimum
• Voltage rating of 24VDC
• Slide actuator type (standard)
• Through-hole mounting with 0.100" (2.54mm) pitch
• PC pin termination style
• Operating temperature range of -20°C ~ 85°C or broader
• Mechanical and electrical life ratings of 2,000 cycles minimum
• ROHS3 compliance and MSL 1 rating

The KAE01LAGT from E-Switch meets all substitution criteria and is classified as a direct equivalent for the NDI01H.

Parameter Comparison

Engineering Selection Recommendations

Both the NDI01H and KAE01LAGT are active production parts with identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• PCB layout constraints related to height above board (NDI01H: 0.197", KAE01LAGT: 0.169")
• Supplier preference and cost considerations
• Mechanical life cycle requirements (both rated for 2,000 cycles)

Both parts satisfy the electrical and mechanical specifications for 24VDC, 25mA SPST switching applications with identical operating temperature ranges and MSL ratings.

Frequently Asked Questions (FAQ)

Q: Can the KAE01LAGT replace the NDI01H in existing designs? A: Yes. Both parts meet identical electrical specifications (SPST, 1 position, 25mA, 24VDC), operate across the same temperature range (-20°C ~ 85°C), and share the same pitch (0.100"), termination style (PC pin), and mounting type (through hole). The primary design consideration is the height above board difference (0.197" vs. 0.169").

Q: What are the key substitution criteria for this DIP switch category? A: Circuit configuration (SPST), position count (1), current rating (25mA minimum), voltage rating (24VDC), actuator type (slide standard), mounting method (through hole), pitch (0.100"), and termination style (PC pin) must remain constant. Operating temperature range, mechanical life, and electrical life must meet or exceed the original specification.

Q: Are there compliance differences between these parts? A: No. Both the NDI01H and KAE01LAGT carry identical ROHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 export classification.

Q: What is the impact of the height difference between these parts? A: The NDI01H has a height above board of 0.197" (5.00mm), while the KAE01LAGT measures 0.169" (4.30mm). This 0.028" difference may affect PCB layout clearance and component stacking in confined spaces. Verify clearance requirements in your specific application before substitution.

Q: Do both parts have the same mechanical and electrical life ratings? A: Yes. Both parts are rated for 2,000 mechanical cycles and 2,000 electrical cycles, making them equivalent for cycle-life applications.
