Part Overview

The Grayhill 76SB02S is a single-pole single-throw (SPST) rocker-actuated DIP switch rated for 150mA at 30VDC. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. The 76SB02S features a through-hole mounting configuration with gold-plated copper alloy contacts, washable construction, and a raised rocker actuator. Current inventory of 1,940 pieces remains available as new original stock.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 76SB02S is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Circuit configuration (SPST)
• Number of positions (2)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Pitch spacing (0.100" / 2.54mm)
• Actuator type (Rocker)

Secondary Compatibility 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
• Contact material and finish (Copper Alloy with Gold plating)

Identified Substitute Categories:

Direct Equivalent (Same Manufacturer): The Grayhill 76SB02ST maintains identical electrical and mechanical specifications to the 76SB02S, with the primary distinction being active product status and RoHS3 compliance. Packaging differs (Tube versus tape seal configuration).

Functional Equivalent (Different Manufacturer): The CTS Electrocomponents 206-2ST provides SPST 2-position through-hole DIP switch functionality with slide actuator configuration. This part operates at reduced current (50mA) and voltage (24VDC) ratings, representing a downrated but functionally compatible alternative for applications not requiring full 150mA/30VDC capacity.

Partial Equivalent (Different Manufacturer): The TE Connectivity ALCOSWITCH 3-435626-6 offers rocker-actuated SPST 2-position through-hole switching with significantly reduced current rating (25mA) and voltage rating (24VDC). This part is suitable only for low-power applications and does not meet the full electrical specifications of the 76SB02S.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option):

The Grayhill 76SB02ST is the preferred substitute for the obsolete 76SB02S. Both parts maintain identical electrical specifications (150mA at 30VDC), mechanical configuration (rocker actuator, raised level), and physical dimensions (0.315" height, 0.280" length). The 76SB02ST is currently in active production status with 6,228 pieces available in inventory. The primary advantage is RoHS3 compliance, which addresses regulatory requirements for new designs. Packaging differs (Tube versus tape seal), but this does not affect functional compatibility. The 76SB02ST is suitable for direct board-level substitution without circuit modification.

For Reduced-Specification Applications:

The CTS Electrocomponents 206-2ST provides an alternative for applications where current and voltage requirements do not exceed 50mA and 24VDC respectively. This part maintains through-hole mounting, PC pin termination, and 0.100" pitch compatibility. The primary trade-off is actuator type (slide versus rocker), which affects user interface but not electrical function. The 206-2ST offers extended electrical life (10,000 cycles) and RoHS3 compliance. This option is suitable only when circuit design permits operation at reduced electrical ratings.

Not Recommended for Direct Substitution:

The TE Connectivity ALCOSWITCH 3-435626-6 does not meet the electrical specifications of the 76SB02S (25mA at 24VDC versus 150mA at 30VDC). Additionally, this part carries REACH-affected status, which may introduce regulatory complications. The recessed rocker actuator configuration differs from the raised actuator of the original part. This option is suitable only for applications with significantly reduced power requirements and where REACH compliance is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 76SB02ST be used as a direct replacement for the 76SB02S without PCB modification?

A: Yes. The 76SB02ST maintains identical electrical ratings (150mA at 30VDC), mechanical configuration (rocker actuator, raised level), and physical footprint (0.315" height, 0.100" pitch). No circuit modification is required. The only difference is packaging format (Tube versus tape seal) and RoHS3 compliance status.

Q: What is the primary reason the 76SB02S is classified as obsolete?

A: The 76SB02S is obsolete due to the availability of the functionally equivalent 76SB02ST, which offers the same electrical and mechanical specifications with active production status and improved regulatory compliance (RoHS3).

Q: Can the CTS Electrocomponents 206-2ST replace the Grayhill 76SB02S in all applications?

A: No. The 206-2ST is rated for 50mA at 24VDC, which is below the 150mA at 30VDC specification of the 76SB02S. This part is suitable only for applications where circuit design permits operation at these reduced electrical ratings. Additionally, the 206-2ST uses a slide actuator rather than a rocker actuator, which affects user interface.

Q: What is the significance of RoHS3 compliance for the 76SB02ST?

A: RoHS3 compliance indicates that the 76SB02ST meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. This is relevant for designs intended for sale in European markets or for customers with regulatory requirements. The original 76SB02S is RoHS non-compliant.

Q: Are there any height or footprint differences between the 76SB02S and 76SB02ST?

A: No. Both parts maintain identical height above board (0.315" / 8.00mm), length (0.280" / 7.11mm), and pitch spacing (0.100" / 2.54mm). They are mechanically interchangeable at the PCB level.

Q: Why does the TE Connectivity 3-435626-6 have a recessed actuator instead of a raised actuator?

A: The recessed (flush) actuator design is a characteristic feature of the TE Connectivity 7000 series DIP switches. This design choice affects user interface ergonomics but does not impact electrical function. The recessed actuator is not compatible with applications requiring a raised actuator profile.

Q: What is the difference between mechanical life and electrical life ratings?

A: Mechanical life refers to the number of physical actuations the switch can withstand before mechanical degradation occurs. Electrical life refers to the number of electrical switching cycles the switch can perform before contact degradation affects electrical performance. Both the 76SB02S and 76SB02ST are rated for 2,000 cycles in both categories.

Q: Is the CTS Electrocomponents 206-2ST washable like the Grayhill parts?

A: Yes. The 206-2ST is washable and features epoxy sealed terminals and tape seal construction, similar to the Grayhill 76SB02S and 76SB02ST.

Q: What does "Moisture Sensitivity Level 1 (Unlimited)" mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This is the least restrictive moisture sensitivity classification and simplifies inventory management.

Q: Can the TE Connectivity 3-435626-6 be used in designs requiring RoHS compliance?

A: No. The 3-435626-6 is RoHS non-compliant. Additionally, it carries REACH-affected status, which may introduce regulatory complications for certain markets. This part is not suitable for designs with RoHS or REACH compliance requirements.
