Grayhill 76SB12S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB12S is a 12-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part features a raised rocker actuator, gold-plated copper alloy contacts, and operates across -40°C to 85°C. Identification of compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB12S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 12
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC pin
• Actuator level: Raised

Secondary Compatibility Criteria:

• Current rating: Equal to or greater than 150mA
• Voltage rating: Equal to or greater than 30VDC
• Operating temperature range: Must encompass -40°C to 85°C or broader
• Contact finish: Gold plated
• Washable: Yes

Two substitute parts are identified:

76SB12ST (Grayhill Inc.): Identical electrical and mechanical specifications to the main part. Differs only in packaging (tube vs. unspecified) and product status (active vs. obsolete). RoHS3 compliant.

206-12ST (CTS Electrocomponents): Meets primary compatibility criteria with 12-position SPST configuration, through-hole mounting, and 0.100" pitch. Differs in actuator type (slide vs. rocker), current rating (50mA vs. 150mA), and voltage rating (24VDC vs. 30VDC). Extended electrical life (10,000 cycles vs. 2,000 cycles). RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 76SB12ST is the recommended substitute for the obsolete 76SB12S. Both parts are manufactured by Grayhill Inc. and share identical electrical specifications (150mA, 30VDC), mechanical configuration (rocker actuator, 12 positions), and physical dimensions. The 76SB12ST is currently in active production status with RoHS3 compliance, addressing both obsolescence and regulatory requirements. Packaging differs (tube vs. unspecified for main part), but electrical and mechanical compatibility is complete.

For Constrained Applications:

The 206-12ST from CTS Electrocomponents is a secondary alternative when the 76SB12ST is unavailable. This part meets the core functional requirements (12-position SPST DIP switch, through-hole mounting, 0.100" pitch) and is RoHS3 compliant. However, the following deviations require circuit-level evaluation:

• Current rating reduced to 50mA (vs. 150mA main part)
• Voltage rating reduced to 24VDC (vs. 30VDC main part)
• Actuator type is slide rather than rocker
• Height above board increased to 0.334" (vs. 0.315")
• Electrical life extended to 10,000 cycles (vs. 2,000 cycles)

The 206-12ST is suitable only for applications where the circuit operates at or below 50mA and 24VDC, and where slide actuator operation is functionally acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 76SB12ST directly replace the 76SB12S without circuit modification?

A: Yes. The 76SB12ST is a direct electrical and mechanical equivalent. Both parts feature identical SPST 12-position configuration, 150mA current rating, 30VDC voltage rating, rocker actuator, through-hole mounting, and 0.100" pitch. The only differences are packaging format and product status (active vs. obsolete). No circuit redesign is required.

Q: What are the limitations of using the 206-12ST as a substitute?

A: The 206-12ST has reduced electrical ratings (50mA vs. 150mA; 24VDC vs. 30VDC) and uses a slide actuator instead of rocker. It is suitable only for applications operating within these lower ratings and where slide actuation is acceptable. The increased height above board (0.334" vs. 0.315") may affect PCB layout clearance. Verify circuit current and voltage requirements before selection.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 76SB12ST and 206-12ST are RoHS3 compliant. The original 76SB12S is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part satisfies this criterion.

Q: What is the difference between the 76SB12S and 76SB12ST packaging?

A: The 76SB12S packaging is unspecified in the provided data. The 76SB12ST is supplied in tube packaging. Both parts are identical in electrical and mechanical specifications. Tube packaging is standard for active production components and does not affect functional performance.

Q: Can I use the 206-12ST in a 150mA, 30VDC circuit?

A: No. The 206-12ST is rated for 50mA maximum at 24VDC. Operating it at 150mA or 30VDC exceeds its electrical ratings and will result in component failure or unsafe operation. Use only within specified ratings: 50mA maximum, 24VDC maximum.

Q: What is the mechanical life difference between these parts?

A: The 76SB12S and 76SB12ST both specify 2,000 mechanical cycles. The 206-12ST does not provide mechanical life data in the available specifications. The 206-12ST specifies 10,000 electrical cycles, which is higher than the other two parts (2,000 cycles each).

Q: Are all three parts washable?

A: Yes. The 76SB12S, 76SB12ST, and 206-12ST are all washable components. The 76SB12S and 76SB12ST feature tape seal protection. The 206-12ST includes epoxy sealed terminals and tape seal.
