Grayhill 76PSB10S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB10S is a 10-position SPST piano DIP switch rated for 150mA at 30VDC with through-hole, right-angle mounting. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The 76PSB10S features gold-plated copper alloy contacts, thermoplastic housing, and operates across -40°C to 85°C. Substitute parts must maintain functional equivalence in circuit topology, electrical ratings, and mechanical form factor while meeting current RoHS and REACH compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB10S is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Circuit configuration (SPST)
• Number of positions (10)
• Actuator type and level (Piano, Raised)
• Mounting type (Through Hole, Right Angle)
• Pitch spacing (0.100" / 2.54mm)
• Contact finish (Gold)
• Operating temperature range (-40°C to 85°C)

Electrical Rating Compatibility: Substitutes must meet or exceed the 150mA current rating and 30VDC voltage rating of the original part. Parts with lower electrical ratings are not functionally equivalent.

Compliance Requirements: Current substitutes must comply with RoHS3 and REACH regulations. The original 76PSB10S is RoHS non-compliant and obsolete; therefore, RoHS3-compliant alternatives are required for new designs and ongoing production.

Parameter Comparison

Engineering Selection Recommendations

76PSB10ST (Grayhill Inc.) - Primary Substitute

The 76PSB10ST is the direct functional equivalent of the 76PSB10S. It maintains identical electrical ratings (150mA, 30VDC), mechanical dimensions, and circuit configuration. The primary distinction is product status: 76PSB10ST is active and ROHS3 compliant, whereas the original 76PSB10S is obsolete and RoHS non-compliant. The 76PSB10ST is packaged in tube format and is the preferred substitute for applications requiring direct replacement without design modification. Inventory availability is significantly higher (6,089 units) compared to the original part.

194-10MST (CTS Electrocomponents) - Limited Compatibility Substitute

The 194-10MST shares the same circuit topology (SPST), position count (10), actuator type (piano, raised), mounting configuration (through-hole, right-angle), and pitch spacing (0.100"). However, this part has reduced electrical ratings: 50mA current (versus 150mA) and 24VDC voltage (versus 30VDC). The 194-10MST is suitable only for applications where the circuit operates at or below 50mA and 24VDC. Height above board is 0.311" (7.90mm) versus 0.301" (7.65mm) for the original, representing a 0.010" (0.25mm) difference that may affect PCB clearance in space-constrained layouts. The 194-10MST offers extended electrical life (7,000 cycles) and is ROHS3 compliant. This part is not a direct replacement for the 76PSB10S in applications requiring full 150mA/30VDC capability.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB10ST be used as a direct replacement for the 76PSB10S?

A: Yes. The 76PSB10ST is functionally equivalent to the 76PSB10S across all critical parameters: SPST circuit, 10 positions, 150mA/30VDC ratings, piano actuator, through-hole right-angle mounting, and 0.100" pitch. The primary difference is compliance status: 76PSB10ST is active and ROHS3 compliant, while 76PSB10S is obsolete and RoHS non-compliant. No circuit redesign is required.

Q: Is the 194-10MST a suitable replacement for the 76PSB10S?

A: The 194-10MST is a suitable replacement only if your circuit operates at 50mA or less and 24VDC or less. If your application requires the full 150mA at 30VDC capability of the 76PSB10S, the 194-10MST will not function as specified. The 194-10MST is a partial substitute based on form factor and actuator type, not electrical equivalence.

Q: What is the difference in packaging between 76PSB10S and 76PSB10ST?

A: The 76PSB10S is supplied with tape seal packaging (indicated by "-" in the original packaging field), while the 76PSB10ST is supplied in tube packaging. Both parts are identical in electrical and mechanical specifications. Tube packaging is standard for active production parts and does not affect component performance.

Q: Will the 194-10MST fit in the same PCB footprint as the 76PSB10S?

A: The 194-10MST has a height above board of 0.311" (7.90mm) compared to 0.301" (7.65mm) for the 76PSB10S, a difference of 0.010" (0.25mm). This minor height difference may affect PCB clearance in applications with tight vertical spacing constraints. All other mechanical dimensions (pitch, length, mounting type) are compatible.

Q: Are there any compliance differences between the substitute parts?

A: Both substitute parts (76PSB10ST and 194-10MST) are ROHS3 compliant and REACH unaffected. The original 76PSB10S is RoHS non-compliant. For new designs and production requiring regulatory compliance, either substitute part meets current standards. The 76PSB10S should not be used in new applications subject to RoHS requirements.

Q: What is the mechanical life difference between the 76PSB10ST and 194-10MST?

A: The 76PSB10ST specifies 2,000 mechanical cycles, matching the original 76PSB10S. The 194-10MST does not specify mechanical life in the provided data. The 194-10MST specifies 7,000 electrical cycles, which exceeds both the 76PSB10S and 76PSB10ST (2,000 electrical cycles each).
