Grayhill 76PSB05S DIP Switch SPST 5-Position Piano Actuator Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB05S is a through-hole DIP switch featuring a single-pole single-throw (SPST) circuit configuration with 5 positions, rated for 150mA at 30VDC. The device employs a raised piano actuator mechanism with gold-plated copper alloy contacts and is designed for PC pin termination in right-angle mounting applications.

The 76PSB05S carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance and production requirements.

Substitute Part Grouping Explanation

Substitute parts for the 76PSB05S are identified based on strict electrical and mechanical parameter compatibility within the DIP switch category. The substitution logic is organized into two groups:

Group 1: Direct Electrical and Mechanical Equivalents

The 76PSB05ST (Grayhill Inc.) maintains identical electrical specifications (SPST, 5 positions, 150mA, 30VDC) and mechanical characteristics (piano actuator, through-hole right-angle mounting, 0.100" pitch, 0.301" height, PC pin termination). The primary difference is packaging format (tube versus bulk) and product status (active versus obsolete). This part qualifies as a direct equivalent suitable for one-to-one replacement.

Group 2: Functional Substitutes with Parameter Deviations

The 194-5MST (CTS Electrocomponents) shares the core functional architecture (SPST, 5 positions, piano actuator, through-hole right-angle mounting, 0.100" pitch, PC pin termination, gold contact finish) but operates at reduced electrical ratings: 50mA current and 24VDC voltage. This part functions as a substitute only in applications where the lower current and voltage ratings are acceptable within the circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 76PSB05ST is the primary substitute for the obsolete 76PSB05S. Both parts are manufactured by Grayhill Inc. and maintain identical electrical ratings (150mA, 30VDC) and mechanical form factors. The 76PSB05ST carries active product status and ROHS3 compliance, providing supply chain continuity and regulatory alignment. Selection of the 76PSB05ST eliminates design modification requirements and ensures functional equivalence in legacy system support.

For Constrained Applications:

The 194-5MST (CTS Electrocomponents) serves as a functional substitute only when circuit design permits operation at reduced electrical specifications (50mA maximum current, 24VDC maximum voltage). This part offers extended electrical life (7,000 cycles versus 2,000 cycles) and ROHS3 compliance. The 0.010" height differential (7.90mm versus 7.65mm) must be evaluated for PCB clearance compatibility. Selection of the 194-5MST requires circuit-level verification that load current and supply voltage remain within the lower rating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB05ST be used as a direct replacement for the 76PSB05S in existing designs?

A: Yes. The 76PSB05ST maintains identical electrical ratings (150mA, 30VDC), circuit configuration (SPST, 5 positions), and mechanical specifications (piano actuator, through-hole right-angle mounting, 0.100" pitch, PC pin termination). The parts are functionally equivalent. The primary difference is product status (active versus obsolete) and packaging format (tube versus bulk).

Q: What are the limitations of using the 194-5MST as a substitute?

A: The 194-5MST operates at reduced electrical ratings: 50mA maximum current (versus 150mA) and 24VDC maximum voltage (versus 30VDC). This part is suitable only for applications where circuit load current and supply voltage remain within these lower limits. The height above board is 0.311" (7.90mm) compared to 0.301" (7.65mm) for the main part; PCB clearance must be verified. The 194-5MST is manufactured by CTS Electrocomponents, not Grayhill Inc.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 76PSB05S is supplied in bulk packaging. The 76PSB05ST and 194-5MST are supplied in tube packaging. Tube packaging may affect procurement processes, handling procedures, and inventory management. Verify packaging requirements with procurement and assembly specifications.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Both the 76PSB05ST and 194-5MST carry ROHS3 compliance certification. The original 76PSB05S is RoHS non-compliant. If design or production requirements mandate RoHS compliance, either substitute part satisfies this requirement. All three parts carry REACH Unaffected status and EAR99 ECCN classification.

Q: What is the mechanical life difference between the main part and substitutes?

A: The 76PSB05S and 76PSB05ST both specify 2,000 mechanical cycles. The 194-5MST does not provide a mechanical life specification in the available data. The 194-5MST specifies 7,000 electrical cycles, which exceeds the 2,000 electrical cycles of the other two parts.

Q: Can the 194-5MST be used in a 30VDC circuit?

A: No. The 194-5MST is rated for 24VDC maximum. Operation at 30VDC exceeds the part's voltage rating and is not permitted. Use of the 194-5MST requires circuit redesign to operate at 24VDC or lower, or selection of an alternative part rated for 30VDC operation.
