Equivalent & Substitute Parts for Grayhill 90HBW05P DIP Switch

Part Overview

The Grayhill 90HBW05P is a surface mount DIP switch with SPST (Single Pole Single Throw) configuration, rated for 25mA at 24VDC. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design support and procurement continuity. The 5-position slide actuator design with gold-plated copper alloy contacts provides reliable switching in industrial and commercial applications. Substitute parts must maintain functional compatibility while accommodating available inventory and active product status where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90HBW05P is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST
• Number of positions must be 5
• Mounting type must be Surface Mount
• Pitch must be 0.100" (2.54mm)
• Actuator type must be Slide (Standard)
• Contact finish must be Gold

Secondary Compatibility Criteria:

• Current rating must equal or exceed 25mA
• Voltage rating must equal or exceed 24VDC
• Operating temperature range must encompass -40°C ~ 85°C
• Termination style must be Gull Wing

Identified Substitutes:

Group 1 - Direct Manufacturer Equivalent: The 90HBW05PT (Grayhill Inc.) satisfies all primary and secondary criteria with identical electrical and mechanical specifications. This part differs only in packaging (Tube versus standard packaging) and product status (Active versus Obsolete).

Group 2 - Cross-Manufacturer Substitute: The 219-5LPST (CTS Electrocomponents) meets all primary compatibility criteria. This part exceeds current rating (100mA versus 25mA) and voltage rating (20VDC versus 24VDC requirement). Height above board differs (0.160" versus 0.190"), and contact material is Beryllium Copper rather than Copper Alloy. Moisture sensitivity level is superior (MSL 1 versus MSL 3).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 90HBW05PT is the primary substitute for the obsolete 90HBW05P. Both parts are manufactured by Grayhill Inc. and share identical electrical specifications (25mA at 24VDC), mechanical dimensions, and operating temperature range. The 90HBW05PT maintains active product status, ensuring long-term availability and supply chain continuity. The only difference is packaging format (Tube). This part is suitable for direct substitution without design modification.

For Cross-Manufacturer Substitution: The CTS Electrocomponents 219-5LPST provides functional substitution with enhanced electrical performance (100mA at 20VDC). This part meets all primary compatibility criteria and offers superior moisture sensitivity rating (MSL 1 versus MSL 3). The extended operating temperature range (-55°C ~ 85°C) provides additional environmental margin. Physical dimensions are comparable with minor height reduction (0.160" versus 0.190"). This part is suitable for applications where the 24VDC requirement can be accommodated within a 20VDC maximum rating, or where enhanced current capacity is beneficial.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part. ECCN classification remains EAR99 for all variants.

Frequently Asked Questions (FAQ)

Q: Can the 90HBW05PT be used as a direct replacement for the 90HBW05P? A: Yes. The 90HBW05PT is a direct functional equivalent with identical electrical ratings (25mA at 24VDC), mechanical configuration, and operating temperature range. The only difference is packaging (Tube). No design modification is required.

Q: What is the primary reason for substituting the 90HBW05P? A: The 90HBW05P is classified as obsolete. The 90HBW05PT provides continuity as an active product from the same manufacturer with identical specifications.

Q: Can the 219-5LPST replace the 90HBW05P in all applications? A: The 219-5LPST meets primary compatibility criteria (SPST, 5-position, surface mount, 0.100" pitch, slide actuator). However, the voltage rating is 20VDC versus the 90HBW05P's 24VDC requirement. Substitution is valid only if the application operates at 20VDC or lower. The 219-5LPST provides higher current capacity (100mA versus 25mA) and superior moisture sensitivity (MSL 1).

Q: Are there footprint compatibility concerns with the 219-5LPST? A: The 219-5LPST has a slightly reduced height above board (0.160" versus 0.190") and marginally shorter length (0.558" versus 0.570"). These dimensional differences are minor and typically do not affect PCB layout compatibility for standard surface mount applications. Verify clearance in your specific design.

Q: What is the difference in contact material between the substitutes? A: The 90HBW05P and 90HBW05PT use Copper Alloy contacts with gold finish. The 219-5LPST uses Beryllium Copper contacts with gold finish. Beryllium Copper provides enhanced contact reliability and is suitable for high-cycle applications.

Q: Do all parts have the same mechanical life rating? A: The 90HBW05P and 90HBW05PT both specify 2,000 mechanical cycles. The 219-5LPST does not provide a mechanical life specification in the available data.

Q: What is the significance of MSL rating differences? A: The 90HBW05P and 90HBW05PT have MSL 3 (168 hours maximum floor life). The 219-5LPST has MSL 1 (unlimited floor life), indicating superior moisture resistance and reduced sensitivity to humidity exposure during storage and handling.

Q: Are all parts RoHS and REACH compliant? A: Yes. All three parts (90HBW05P, 90HBW05PT, and 219-5LPST) are ROHS3 compliant and REACH unaffected.

Q: What packaging options are available? A: The 90HBW05P is supplied in standard packaging. The 90HBW05PT and 219-5LPST are supplied in Tube packaging.
