Grayhill 76PSB02S DIP Switch SPST Piano Actuator Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB02S is a single-pole single-throw (SPST) DIP switch with piano actuator, rated for 150mA at 30VDC. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement. The 76PSB02S features a 2-position through-hole configuration with right-angle mounting and gold-plated copper alloy contacts suitable for applications requiring reliable switching in the specified voltage and current range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76PSB02S is determined by strict equivalence across the following critical parameters: circuit configuration (SPST), number of positions (2), actuator type (piano with raised level), mounting method (through-hole right-angle), pitch (0.100"), and operating temperature range (-40°C to 85°C). The substitute parts identified are grouped based on their ability to maintain these core functional and mechanical characteristics.

Group 1 - Direct Functional Equivalent: The 76PSB02ST (Grayhill Inc.) maintains identical electrical specifications (150mA, 30VDC), mechanical dimensions, and actuator configuration. The primary distinction is product status (active versus obsolete) and packaging format (tube versus bulk).

Group 2 - Electrical Derating Substitute: The 194-2MST (CTS Electrocomponents) operates at reduced current (50mA) and voltage (24VDC) ratings compared to the 76PSB02S. This part is suitable only for applications where the load requirements do not exceed 50mA at 24VDC. Mechanical compatibility is maintained through identical mounting type, pitch, and actuator configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 76PSB02ST is the primary substitute for the obsolete 76PSB02S. Both parts are manufactured by Grayhill Inc. and maintain identical electrical ratings (150mA, 30VDC), mechanical dimensions, and functional characteristics. The 76PSB02ST carries active product status and ROHS3 compliance, making it suitable for new designs and ongoing production support. The only operational difference is packaging format (tube versus bulk).

For Derating Applications: The 194-2MST (CTS Electrocomponents) is applicable only when circuit requirements are limited to 50mA maximum current and 24VDC maximum voltage. This part maintains mechanical and actuator compatibility but operates at reduced electrical ratings. The 194-2MST provides extended electrical life (7,000 cycles versus 2,000 cycles) and ROHS3 compliance. Height above board is marginally increased (0.311" versus 0.301"), which may require PCB layout verification in space-constrained applications.

Compliance Considerations: Both substitute parts achieve ROHS3 compliance and REACH unaffected status, whereas the original 76PSB02S is RoHS non-compliant. Selection of either substitute improves regulatory compliance for new product designs.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB02ST directly replace the 76PSB02S without circuit modification?

A: Yes. The 76PSB02ST maintains identical electrical specifications (150mA, 30VDC), mechanical dimensions, pitch, and actuator configuration. No circuit modification is required. The primary difference is product status (active versus obsolete) and packaging format.

Q: What are the limitations of using the 194-2MST as a substitute?

A: The 194-2MST operates at reduced electrical ratings: 50mA maximum current and 24VDC maximum voltage, compared to 150mA and 30VDC for the 76PSB02S. This part is suitable only for applications where load requirements do not exceed these reduced ratings. Additionally, the height above board is 0.311" versus 0.301", requiring verification in space-constrained PCB layouts.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 76PSB02S is supplied in bulk packaging, while both 76PSB02ST and 194-2MST are supplied in tube packaging. Tube packaging may affect procurement quantities and handling procedures.

Q: Do the substitute parts meet modern compliance standards?

A: Both 76PSB02ST and 194-2MST are ROHS3 compliant and REACH unaffected. The original 76PSB02S is RoHS non-compliant. Selection of either substitute improves regulatory compliance for new designs.

Q: What is the mechanical life difference between the 194-2MST and the main part?

A: The 194-2MST does not specify mechanical life in the provided data. The 76PSB02S and 76PSB02ST both specify 2,000 mechanical cycles. The 194-2MST specifies 7,000 electrical cycles, which exceeds the 2,000 electrical cycles of the main part.

Q: Can both substitute parts be used interchangeably in the same circuit?

A: No. The 76PSB02ST is a direct equivalent and can replace the 76PSB02S without modification. The 194-2MST requires circuit analysis to confirm that load requirements do not exceed 50mA at 24VDC. These parts are not interchangeable in all applications.
