Equivalent & Substitute Parts for 90HBW03PRT

Part Overview

The 90HBW03PRT is a DIP slide switch manufactured by Grayhill Inc., configured as a single-pole single-throw (SPST) device with three positions. This surface mount component operates at 25mA and 24VDC, featuring a standard slide actuator with flush, recessed actuation level. The part is currently active in production and widely used in industrial control, telecommunications, and consumer electronics applications where compact, reliable switching is required. Substitute parts are identified when equivalent electrical ratings, mechanical configurations, and compliance certifications are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90HBW03PRT is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Circuit type (SPST), number of positions (3), current rating (25mA), and voltage rating (24VDC) must be identical. These parameters define the functional switching capability and load-handling capacity.

Mechanical Equivalence: Actuator type (slide, standard), actuator level (flush, recessed), mounting type (surface mount), termination style (gull wing), and pitch (0.100" / 2.54mm) must match to ensure physical and electrical compatibility with printed circuit board layouts and assembly processes.

Compliance Equivalence: RoHS3 compliance is required for all substitutes to meet regulatory requirements in target markets.

The substitute part 1-1825059-2 from TE Connectivity ALCOSWITCH Switches meets all electrical, mechanical, and compliance criteria for direct substitution with the 90HBW03PRT.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (90HBW03PRT): The Grayhill Inc. 90HBW03PRT is the specified component and remains the first choice when available. It is active in production, ROHS3 compliant, and REACH unaffected. The part demonstrates mechanical and electrical life ratings of 2,000 cycles, providing extended operational durability. Current inventory of 783 pieces supports immediate procurement.

Substitute Selection (1-1825059-2): The TE Connectivity ALCOSWITCH 1-1825059-2 is a qualified equivalent substitute. It meets all critical electrical and mechanical parameters required for direct substitution. The substitute is ROHS3 compliant and REACH unaffected, satisfying regulatory requirements. The substitute features superior moisture sensitivity characteristics (MSL 1 versus MSL 3), reducing handling and storage constraints. Mechanical and electrical life ratings of 1,000 cycles are lower than the primary part but remain adequate for standard applications. Higher inventory availability (5,792 pieces) may support expedited procurement when needed. The substitute is packaged in Cut Tape (CT) format, whereas the primary part uses Tape & Reel (TR) packaging; assembly process compatibility must be confirmed.

Compliance Verification: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronics manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825059-2 be used as a direct replacement for the 90HBW03PRT in existing designs?

A: Yes. The 1-1825059-2 meets all critical electrical and mechanical specifications: SPST circuit, 3 positions, 25mA current rating, 24VDC voltage rating, slide actuator, flush/recessed actuation, surface mount configuration, gull wing termination, and 0.100" pitch. Physical dimensions are within tolerance for PCB layout compatibility.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Mechanical and electrical life ratings—90HBW03PRT rated for 2,000 cycles versus 1-1825059-2 rated for 1,000 cycles; (2) Moisture sensitivity level—90HBW03PRT is MSL 3 (168 hours) versus 1-1825059-2 is MSL 1 (unlimited); (3) Operating temperature range—90HBW03PRT operates from -40°C to 85°C versus 1-1825059-2 from -30°C to 85°C; (4) Body material—90HBW03PRT uses thermoplastic versus 1-1825059-2 uses polyphenylene sulfide (PPS); (5) Packaging format—90HBW03PRT supplied in Tape & Reel versus 1-1825059-2 in Cut Tape.

Q: Are there any assembly process considerations when switching between these parts?

A: Yes. The primary part (90HBW03PRT) is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The substitute (1-1825059-2) is supplied in Cut Tape (CT) packaging, which may require manual handling or different feeder compatibility depending on assembly equipment. Confirm feeder compatibility with your assembly partner before procurement.

Q: Which part should be selected for applications requiring extended operational life?

A: The 90HBW03PRT is rated for 2,000 mechanical and electrical cycles, compared to 1,000 cycles for the 1-1825059-2. For applications requiring extended cycle life, the primary part is the appropriate selection.

Q: Are both parts suitable for high-humidity storage environments?

A: The 1-1825059-2 has superior moisture handling characteristics (MSL 1, unlimited storage) compared to the 90HBW03PRT (MSL 3, 168-hour limit). For applications or storage environments with high humidity exposure, the 1-1825059-2 is the preferred selection.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the 90HBW03PRT and 1-1825059-2 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronics manufacturing and distribution in regulated markets.
