Equivalent & Substitute Parts for Grayhill 76SB04S DIP Switch

Part Overview

The Grayhill 76SB04S is a DIP switch featuring SPST (Single Pole Single Throw) circuit configuration with 4 positions, rocker actuator, and rated for 150mA at 30VDC. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement planning. The 76SB04S provides through-hole mounting with gold-plated copper alloy contacts and operates across -40°C to 85°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB04S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 4
• Mounting type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Actuator level: Raised

Electrical Performance Criteria:

• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC
• Operating temperature range must encompass -40°C to 85°C

Mechanical Criteria:

• Height above board and overall dimensions must be compatible with existing PCB layouts
• Contact material and finish specifications must support equivalent electrical performance

Two substitute parts meet these criteria with varying degrees of parameter alignment.

Engineering Selection Recommendations

76SB04ST (Grayhill Inc.) - Primary Substitute

The 76SB04ST is the direct functional equivalent to the 76SB04S. Both parts share identical electrical ratings (150mA, 30VDC), mechanical dimensions (0.315" height, 0.100" pitch), actuator type (rocker), and operating temperature range (-40°C to 85°C). The 76SB04ST is currently in active production status with ROHS3 compliance, addressing the obsolescence of the original part. This substitute requires no design modifications and provides direct pin-for-pin compatibility. The transition from non-compliant to ROHS3-compliant status aligns with current regulatory requirements.

206-4ST (CTS Electrocomponents) - Alternative Substitute

The 206-4ST provides functional substitution with design considerations. This part maintains SPST configuration, 4-position count, through-hole mounting, and 0.100" pitch compatibility. However, the 206-4ST operates at reduced electrical ratings (50mA at 24VDC) compared to the 76SB04S specification (150mA at 30VDC). The actuator type differs (slide versus rocker), and height above board is increased (0.334" versus 0.315"). The 206-4ST is suitable only for applications where the lower current and voltage ratings are acceptable and where slide actuator operation is compatible with user interface requirements. Extended electrical life (10,000 cycles) and broader operating temperature range (-55°C to 85°C) may provide advantages in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 76SB04ST directly replace the 76SB04S without PCB modifications?

A: Yes. The 76SB04ST maintains identical pitch (0.100"), height above board (0.315"), mounting type (through hole), and termination style (PC pin). No PCB layout changes are required.

Q: What are the electrical limitations when using the 206-4ST as a substitute?

A: The 206-4ST is rated for 50mA at 24VDC, compared to the 76SB04S rating of 150mA at 30VDC. Applications requiring the full 150mA current capacity or 30VDC voltage rating cannot use the 206-4ST without circuit redesign.

Q: Does the slide actuator on the 206-4ST affect mechanical compatibility?

A: Yes. The 206-4ST uses a slide actuator while the 76SB04S uses a rocker actuator. User interface operation and panel cutout requirements differ between these actuator types. Physical mounting compatibility exists, but functional operation differs.

Q: Are there compliance differences between the substitute parts?

A: The 76SB04S is RoHS non-compliant. Both 76SB04ST and 206-4ST are ROHS3 compliant. For applications subject to RoHS regulations, either substitute part satisfies compliance requirements.

Q: What is the height difference between the 206-4ST and the original part?

A: The 206-4ST height above board is 0.334" (8.48mm) compared to 0.315" (8.00mm) for the 76SB04S. This 0.019" difference may affect clearance in space-constrained applications.

Q: Which substitute part provides the longest operational life?

A: The 206-4ST specifies 10,000 electrical cycles compared to 2,000 cycles for both the 76SB04S and 76SB04ST. However, this advantage applies only to applications where the reduced electrical ratings (50mA, 24VDC) are acceptable.
