NHDS02T Equivalent & Substitute Parts

Part Overview

The NHDS02T is a DIP slide switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 2 positions. It is rated for 25mA at 24VDC and features surface mount gull wing termination with a flush, recessed slide actuator. The NHDS02T is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NHDS02T is determined by strict equivalence across the following electrical and mechanical parameters:

• Circuit configuration (SPST, 2 positions)
• Current and voltage ratings (25mA, 24VDC)
• Actuator type and level (Slide Standard, Flush Recessed)
• Mounting and termination (Surface Mount, Gull Wing)
• Pitch specification (0.050", Half)
• Contact finish (Gold)
• Washability and tape seal features
• Compliance certifications (ROHS3, REACH Unaffected)

Two substitute parts meet these criteria: IKH0203000 (APEM Inc.) and 97C02ST (Grayhill Inc.). Both maintain functional and mechanical compatibility with the original NHDS02T specification.

Parameter Comparison

Engineering Selection Recommendations

Both IKH0203000 and 97C02ST are active production parts suitable for replacing the obsolete NHDS02T. Selection between them is based on the following considerations:

IKH0203000 (APEM Inc.): This substitute maintains APEM Inc. manufacturer continuity and is available in higher inventory (4,350 pcs). It meets all electrical and mechanical requirements. The operating temperature range is narrower (-20°C to 70°C) compared to the original NHDS02T (-40°C to 85°C), which may be a constraint in extreme temperature applications. Mechanical life is not specified for this part.

97C02ST (Grayhill Inc.): This substitute matches the original NHDS02T operating temperature range (-40°C to 85°C) and mechanical life specification (1,000 cycles). It introduces a manufacturer change from APEM Inc. to Grayhill Inc. Electrical life is not specified for this part. Inventory availability is 2,000 pcs.

Both parts carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1). Selection should prioritize temperature range requirements and manufacturer qualification status within your design environment.

Frequently Asked Questions (FAQ)

Q: Can IKH0203000 be used in applications requiring the full -40°C to 85°C temperature range?

A: No. IKH0203000 is rated for -20°C to 70°C operation. Applications requiring the full -40°C to 85°C range must use 97C02ST or the original NHDS02T if available.

Q: Are there differences in contact material between the substitutes?

A: Yes. NHDS02T and 97C02ST use Copper Alloy contacts, while IKH0203000 uses Phosphor Bronze contacts. Both materials are gold-finished and suitable for 24VDC, 25mA switching applications.

Q: What is the difference between Tape and Tube packaging?

A: NHDS02T is supplied in Tape packaging. Both substitutes (IKH0203000 and 97C02ST) are supplied in Tube packaging. Packaging format may affect handling, storage, and assembly line compatibility. Verify compatibility with your pick-and-place equipment.

Q: Are mechanical and electrical life specifications identical across all three parts?

A: No. NHDS02T specifies 1,000 cycles for both mechanical and electrical life. IKH0203000 specifies 1,000 cycles electrical life but does not specify mechanical life. 97C02ST specifies 1,000 cycles mechanical life but does not specify electrical life. For applications with defined cycle life requirements, cross-reference against your specific operational profile.

Q: Do all three parts meet RoHS and REACH compliance?

A: Yes. NHDS02T, IKH0203000, and 97C02ST are all ROHS3 Compliant and REACH Unaffected, with MSL rating of 1 (Unlimited).
