Grayhill 90HBJ05P DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 90HBJ05P is a surface mount DIP switch with SPST (Single Pole Single Throw) configuration, rated for 25mA at 24VDC. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. The 5-position slide actuator design with gold-plated copper alloy contacts provides reliable switching performance across industrial and commercial applications operating between -40°C and 85°C.

Engineering Selection Recommendations

90HBJ05PT (Grayhill Inc.) – Recommended Primary Substitute

The 90HBJ05PT is the direct manufacturer equivalent of the obsolete 90HBJ05P. This part maintains identical electrical specifications (25mA at 24VDC), mechanical dimensions, and performance characteristics. The 90HBJ05PT is classified as Active product status, ensuring ongoing availability and supply chain continuity. The part achieves ROHS3 compliance, addressing regulatory requirements that the original 90HBJ05P does not meet. Moisture sensitivity level remains at MSL 3, consistent with the original specification. This substitute is the optimal choice for direct replacement in existing designs without circuit modification.

219-5LPSTJ (CTS Electrocomponents) – Alternative Cross-Manufacturer Substitute

The 219-5LPSTJ provides an alternative cross-manufacturer option with enhanced electrical performance characteristics. This part exceeds the original current rating (100mA versus 25mA) and operates at 20VDC, which is within acceptable tolerance for 24VDC applications. The extended operating temperature range (-55°C to 85°C) provides additional thermal margin. The 219-5LPSTJ achieves ROHS3 compliance and offers superior moisture sensitivity (MSL 1 with unlimited humidity exposure). The beryllium copper contact material provides enhanced durability compared to the copper alloy contacts of the original part. Height above board is reduced by 0.020" (0.51mm), which may require PCB layout verification. This substitute is suitable for applications requiring enhanced electrical performance and improved environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can the 90HBJ05PT be used as a direct replacement for the 90HBJ05P without circuit modification?

A: Yes. The 90HBJ05PT maintains identical electrical ratings (25mA at 24VDC), mechanical dimensions, and functional characteristics. No circuit modification is required. The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What are the key differences between the 90HBJ05PT and 219-5LPSTJ substitutes?

A: The 90HBJ05PT is a direct Grayhill manufacturer equivalent with identical specifications. The 219-5LPSTJ is a CTS Electrocomponents cross-manufacturer substitute with higher current rating (100mA), lower voltage rating (20VDC), extended temperature range (-55°C to 85°C), and improved moisture sensitivity (MSL 1). The 219-5LPSTJ has a reduced height above board (0.200" versus 0.220").

Q: Is the 219-5LPSTJ suitable for 24VDC applications if it is rated for 20VDC?

A: The 219-5LPSTJ is rated for 20VDC operation. Application at 24VDC exceeds the specified voltage rating. Circuit design must confirm that 20VDC rating is acceptable for the intended application, or the 90HBJ05PT should be selected to maintain the original 24VDC specification.

Q: What is the impact of the 0.020" height difference between the 90HBJ05P and 219-5LPSTJ?

A: The 219-5LPSTJ has a reduced height above board (0.200" versus 0.220"). PCB layout and component clearance must be verified to confirm compatibility with existing designs. The reduced height may provide benefits in space-constrained applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 90HBJ05PT and 219-5LPSTJ are ROHS3 compliant. The original 90HBJ05P is RoHS non-compliant. Selection of either substitute addresses RoHS regulatory requirements.

Q: What is the difference in moisture sensitivity between the substitutes?

A: The 90HBJ05PT maintains MSL 3 (168 hours maximum exposure) consistent with the original part. The 219-5LPSTJ offers superior moisture sensitivity at MSL 1 (unlimited humidity exposure), providing enhanced reliability in humid environments and extended shelf life without baking requirements.

Q: Can the 90HBJ05P be used interchangeably with the 219-5LPSTJ in existing designs?

A: Functional interchangeability requires verification of voltage rating compatibility. The 219-5LPSTJ is rated for 20VDC, while the original part is rated for 24VDC. If the application operates at 24VDC, the 90HBJ05PT is the appropriate substitute. The 219-5LPSTJ is suitable only if the application voltage is 20VDC or lower.

Q: What packaging options are available for the substitute parts?

A: Both substitute parts (90HBJ05PT and 219-5LPSTJ) are supplied in Tube packaging. The original 90HBJ05P packaging is listed as dash (-), indicating standard packaging format.

Q: Are there any mechanical life cycle differences between the substitutes?

A: The 90HBJ05PT maintains the original mechanical life specification of 2,000 cycles. The 219-5LPSTJ does not specify mechanical life rating. Both parts specify 2,000 cycles electrical life.
