Equivalent & Substitute Parts for Grayhill 90HBW09P DIP Switch

Part Overview

The Grayhill 90HBW09P is a 9-position surface mount DIP switch with SPST circuit configuration, rated for 25mA at 24VDC. This component features a slide actuator with gold-plated copper alloy contacts and is designed for applications requiring reliable switching in compact form factors. The product is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Alternative components must maintain functional compatibility while accommodating available inventory and active product status where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 90HBW09P is based on electrical and mechanical parameter compatibility within the DIP switch category. The primary constraint is the 9-position configuration combined with SPST circuit topology, 25mA current rating, and 24VDC voltage specification. Surface mount packaging with 0.100" pitch and gull wing termination establishes the mechanical interface requirements.

Two substitute relationships are identified:

Direct Substitute (219-9LPST by CTS Electrocomponents): Maintains identical position count (9), circuit type (SPST), mounting method (surface mount), pitch (0.100"), and termination style (gull wing). Electrical ratings exceed the original specification (100mA vs. 25mA; 20VDC vs. 24VDC). This component is active product status with superior moisture sensitivity rating (MSL 1 vs. MSL 3).

Similar Substitute (3-1825059-6 by TE Connectivity ALCOSWITCH): Shares SPST circuit, surface mount configuration, pitch, and termination style. Electrical ratings match the original (25mA, 24VDC). Position count differs (7 vs. 9), resulting in reduced array size and modified PCB footprint. This component is active product status with established compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Position Count):

The CTS Electrocomponents 219-9LPST provides the closest functional equivalent to the 90HBW09P. Both components feature 9-position SPST configuration with matching mechanical interfaces (0.100" pitch, gull wing termination, surface mount). The 219-9LPST exceeds electrical specifications (100mA vs. 25mA current capacity; 20VDC vs. 24VDC voltage rating), ensuring compatibility with the original design envelope. Active product status and superior moisture sensitivity rating (MSL 1) provide long-term supply chain stability and enhanced reliability in humid environments. ROHS3 compliance is maintained across both components.

For Modified Design Integration (Reduced Position Count):

The TE Connectivity ALCOSWITCH 3-1825059-6 serves as a substitute when application requirements permit reduction from 9 to 7 switch positions. Electrical ratings (25mA, 24VDC) match the original specification exactly. Active product status and established compliance certifications support procurement continuity. PCB layout modification is required due to reduced array size (0.778" vs. 0.970" length). Electrical life rating (1,000 cycles) is lower than both the original and CTS alternative, requiring evaluation against application duty cycle requirements.

Compliance Considerations:

All three components maintain ROHS3 compliance and EAR99 export classification. The 219-9LPST offers superior environmental handling characteristics (MSL 1 vs. MSL 3), reducing moisture-related failure risk in storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the CTS 219-9LPST directly replace the Grayhill 90HBW09P without PCB modification?

A: Yes. Both components share identical position count (9), pitch (0.100"), termination style (gull wing), and mounting method (surface mount). PCB footprint compatibility is maintained. Height above board differs slightly (0.160" vs. 0.190"), which does not affect electrical function or assembly clearance in standard applications.

Q: What is the primary difference between the CTS and TE Connectivity substitutes?

A: The CTS 219-9LPST maintains the 9-position configuration, while the TE Connectivity 3-1825059-6 reduces to 7 positions. The CTS option requires no PCB layout changes. The TE option requires PCB redesign but provides exact electrical rating matching (25mA, 24VDC).

Q: Does the higher current rating of the CTS 219-9LPST (100mA vs. 25mA) create compatibility issues?

A: No. Higher current capacity is a superset of the original specification. The component will operate safely at 25mA loads. This provides design margin and potential for future application expansion.

Q: How do moisture sensitivity levels affect component selection?

A: The CTS 219-9LPST (MSL 1) requires no moisture bake-out prior to assembly and has unlimited shelf life under controlled storage. The original 90HBW09P (MSL 3) requires 168-hour bake-out if moisture absorption occurs. For high-volume or extended storage applications, the CTS component reduces handling complexity.

Q: Are all three components RoHS3 compliant?

A: Yes. The 90HBW09P, 219-9LPST, and 3-1825059-6 all meet ROHS3 compliance requirements, ensuring compatibility with current environmental regulations and customer specifications.

Q: What packaging formats are available for these substitutes?

A: The CTS 219-9LPST is supplied in Tube packaging. The TE Connectivity 3-1825059-6 is supplied in Tape & Reel (TR) format. Packaging selection should align with assembly process requirements and volume specifications.

Q: Can the TE Connectivity 3-1825059-6 be used if the application requires all 9 positions?

A: No. The 3-1825059-6 provides only 7 positions. Application redesign would be required to accommodate the reduced switch array, or the CTS 219-9LPST should be selected for full position compatibility.
