Equivalent & Substitute Parts for 90HBJ03RT

Part Overview

The 90HBJ03RT is a DIP slide switch manufactured by Grayhill Inc., classified as a Surface Mount SPST (Single Pole Single Throw) component with 3-position capability. This switch is rated for 25mA at 24VDC and features a standard slide actuator with gold-plated copper alloy contacts. The product is Active status and RoHS Compliant, making it suitable for modern electronic assemblies requiring low-current switching applications.

Equivalent and substitute parts are identified when alternative components meet the same electrical specifications, mechanical interface requirements, and regulatory compliance standards. Substitutes enable procurement flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90HBJ03RT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit type: SPST (Single Pole Single Throw)
• Number of positions: 3
• Current rating: 25mA minimum
• Voltage rating: 24VDC minimum
• Actuator type: Slide (Standard)
• Mounting method: Surface Mount
• Pitch spacing: 0.100" (2.54mm)
• Contact material and finish: Copper Alloy with Gold plating
• RoHS compliance status

Allowable Variations:

• Termination style (J Lead vs. Gull Wing) — acceptable if PCB footprint accommodates
• Height above board — acceptable within assembly clearance limits
• Operating temperature range — acceptable if substitute range encompasses application requirements
• Mechanical and electrical life cycles — acceptable if substitute meets or exceeds minimum requirements
• Body material — acceptable if electrical and mechanical performance is maintained
• Moisture sensitivity level — acceptable if storage and handling procedures are adjusted accordingly

The substitute part 1-1825059-2 (TE Connectivity ALCOSWITCH Switches) meets all mandatory matching parameters and is therefore qualified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 90HBJ03RT (Grayhill Inc.)

Use the 90HBJ03RT when:

• Original design specification requires J Lead termination
• Application requires operation at temperatures below -30°C
• Mechanical or electrical cycle life must reach 2,000 cycles
• Moisture sensitivity level 3 (168 hours) is acceptable for your storage and handling procedures
• Grayhill supply chain is preferred or contractually specified

Substitute Part: 1-1825059-2 (TE Connectivity ALCOSWITCH Switches)

Use 1-1825059-2 as a substitute when:

• PCB layout accommodates Gull Wing termination style
• Application operates within -30°C to 85°C temperature range
• Mechanical and electrical cycle life requirements do not exceed 1,000 cycles
• Superior moisture resistance (MSL 1, Unlimited) is beneficial for your assembly and storage environment
• TE Connectivity supply chain availability is advantageous
• Tape Seal packaging feature is required for automated assembly processes

Compliance Verification:

Both parts maintain RoHS and REACH compliance. The substitute part (1-1825059-2) carries ROHS3 certification, which represents the current regulatory standard. Both parts are classified as EAR99 for export control purposes and share the same HTSUS tariff code.

Frequently Asked Questions (FAQ)

Q: Can I use 1-1825059-2 as a direct replacement for 90HBJ03RT on my existing PCB?

A: Direct replacement requires verification of two factors: (1) PCB footprint compatibility with Gull Wing termination (substitute) versus J Lead termination (original), and (2) clearance verification for the lower profile height of 0.177" versus 0.220". If your PCB was designed for J Lead termination, footprint modification is necessary.

Q: What is the difference between J Lead and Gull Wing termination?

A: J Lead termination features a right-angle lead that wraps under the component body, while Gull Wing termination features leads that extend outward at an angle. These require different PCB pad layouts and solder reflow profiles. Consult your PCB design documentation to confirm which termination style your layout supports.

Q: The substitute part has lower mechanical and electrical life ratings (1,000 cycles vs. 2,000 cycles). Is this acceptable?

A: Acceptability depends on your application's actual cycle requirements. If your design operates the switch fewer than 1,000 times over its lifetime, the substitute part is suitable. If your application requires more than 1,000 cycles, the original 90HBJ03RT is required.

Q: What does MSL 3 versus MSL 1 mean for my assembly process?

A: MSL (Moisture Sensitivity Level) indicates how long a component can be exposed to ambient humidity before soldering. MSL 3 allows 168 hours of exposure; MSL 1 allows unlimited exposure. The substitute part (MSL 1) offers greater flexibility in storage and handling, reducing the risk of moisture-induced defects during assembly.

Q: Are both parts RoHS compliant?

A: Yes. The original part (90HBJ03RT) is RoHS Compliant. The substitute part (1-1825059-2) is ROHS3 Compliant, which is the current regulatory standard. Both meet RoHS requirements for lead-free construction.

Q: Can I use the substitute part if my application requires operation below -30°C?

A: No. The substitute part (1-1825059-2) is rated for -30°C to 85°C. If your application requires operation below -30°C, the original part (90HBJ03RT), rated for -40°C to 85°C, is required.

Q: What is the significance of the Tape Seal feature on the substitute part?

A: Tape Seal packaging indicates the substitute part is supplied in Cut Tape format with sealed packaging, which is optimized for automated pick-and-place assembly processes. This may reduce handling time and improve assembly efficiency compared to alternative packaging formats.

Q: Do both parts use the same contact material?

A: Yes. Both parts feature Copper Alloy contacts with Gold finish, ensuring equivalent electrical performance and contact reliability.

Q: What should I verify before approving the substitute part for production use?

A: Verify (1) PCB footprint compatibility with Gull Wing termination, (2) operating temperature range suitability, (3) mechanical/electrical cycle life requirements, (4) moisture sensitivity level compatibility with your assembly environment, and (5) clearance for the lower profile height.
