Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 90HBW03RT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST)
• Number of positions (3)
• Current rating (25mA)
• Voltage rating (24VDC)
• Actuator type (Slide Standard)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Pitch (0.100" / 2.54mm)
• Contact material (Copper Alloy)
• Contact finish (Gold)
• RoHS compliance status (ROHS3 Compliant)

The TE Connectivity ALCOSWITCH Switches part number 1-1825059-2 meets all mandatory matching parameters and qualifies as a direct substitute. Variations in secondary parameters such as packaging format, body material, mechanical life cycles, operating temperature range, and moisture sensitivity level do not preclude substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both the Grayhill 90HBW03RT and TE Connectivity 1-1825059-2 are active-status products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Selection Considerations Based on Provided Specifications:

The Grayhill 90HBW03RT is specified for operation across -40°C to 85°C and provides 2,000 mechanical and electrical life cycles. This component is suitable for applications requiring extended temperature range coverage and higher cycle durability.

The TE Connectivity 1-1825059-2 operates across -30°C to 85°C with 1,000 mechanical and electrical life cycles. This substitute offers superior moisture sensitivity performance (MSL 1 versus MSL 3) and includes washable construction with tape seal features. The lower operating temperature floor (-30°C versus -40°C) and reduced cycle life (1,000 versus 2,000 cycles) represent the primary specification differences.

Both components share identical electrical ratings (25mA, 24VDC), circuit configuration (SPST), and mechanical interface specifications (gull wing termination, 0.100" pitch, surface mount). Physical dimensions differ marginally: the TE Connectivity part is 0.008" shorter in height and 0.008" longer in overall length.

Selection between these parts depends on application-specific requirements for temperature extremes, cycle life expectations, and environmental exposure conditions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1825059-2 replace the Grayhill 90HBW03RT in all applications?

A: The TE Connectivity 1-1825059-2 is electrically and mechanically equivalent for applications operating within -30°C to 85°C and requiring up to 1,000 switching cycles. Applications requiring operation below -30°C or exceeding 1,000 cycles require the Grayhill 90HBW03RT.

Q: What is the impact of the different packaging formats (Tape & Reel versus Cut Tape)?

A: Packaging format affects procurement and assembly logistics but does not impact electrical or mechanical performance. Tape & Reel (TR) packaging is optimized for high-volume automated assembly. Cut Tape (CT) packaging is suitable for lower-volume or manual assembly operations. Component selection should align with production volume and assembly equipment capabilities.

Q: Are there dimensional compatibility concerns between these parts?

A: Both components use identical pitch (0.100" / 2.54mm) and gull wing termination, ensuring PCB footprint compatibility. Height above board differs by 0.013" (0.33mm), which is negligible for most applications. Overall length differs by 0.008" (0.20mm). These dimensional variations do not affect standard PCB layout or assembly processes.

Q: What does the difference in Moisture Sensitivity Level (MSL) mean for component handling?

A: The Grayhill 90HBW03RT is rated MSL 3 (168 hours floor life), requiring controlled storage and handling to prevent moisture absorption. The TE Connectivity 1-1825059-2 is rated MSL 1 (unlimited floor life), permitting extended storage without moisture-related degradation. MSL rating affects component shelf life and storage environment requirements but does not impact in-service performance.

Q: Why do the mechanical and electrical life ratings differ between these parts?

A: The Grayhill 90HBW03RT specifies 2,000 cycles for both mechanical and electrical life. The TE Connectivity 1-1825059-2 specifies 1,000 cycles. These values represent manufacturer-tested performance under specified conditions. Applications requiring extended cycle life should specify the Grayhill component.

Q: Are both parts suitable for industrial control applications?

A: Both components are rated for 24VDC operation at 25mA with SPST configuration, meeting standard industrial control voltage and current requirements. Selection depends on specific operating temperature range, cycle life expectations, and environmental exposure conditions of the target application.
