Grayhill 76SB02 DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB02 is a through-hole DIP switch with SPST (Single Pole Single Throw) configuration, rated for 150mA at 30VDC. This component features a rocker actuator and is designed for applications requiring manual circuit switching in compact form factors. The 76SB02 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB02 is determined by the following critical parameters:

Primary Compatibility Criteria:

Circuit configuration (SPST)
Number of positions (2)
Mounting type (Through Hole)
Pitch spacing (0.100" / 2.54mm)

Engineering Selection Recommendations

76SB02T (Grayhill Inc.) - Primary Substitute

The 76SB02T is the direct functional equivalent of the 76SB02. Both components share identical electrical ratings (150mA, 30VDC), mechanical specifications (rocker actuator, 2,000-cycle life), and physical dimensions. The 76SB02T is currently in active production status with ROHS3 compliance, addressing the regulatory limitations of the obsolete 76SB02. This part is the preferred replacement for direct substitution in new designs and legacy system updates.

206-2 (CTS Electrocomponents) - Conditional Substitute

The CTS 206-2 provides functional substitution with important parameter deviations. The current rating is reduced to 50mA (versus 150mA), and voltage rating is 24VDC (versus 30VDC). The actuator type differs (slide versus rocker), and physical height increases to 0.334" (8.48mm). The 206-2 offers extended electrical life (10,000 cycles) and broader operating temperature range (-55°C to 85°C). This part is suitable only for applications where the reduced current and voltage ratings are acceptable and where the slide actuator form factor is compatible with the mechanical design.

Frequently Asked Questions (FAQ)

Q: Can the 76SB02T directly replace the 76SB02 without circuit modification?

A: Yes. The 76SB02T is electrically and mechanically identical to the 76SB02. Both components have identical current ratings (150mA), voltage ratings (30VDC), actuator types (rocker), and physical dimensions. Direct substitution is possible without circuit redesign.

Q: What are the limitations of using the CTS 206-2 as a substitute?

A: The 206-2 has reduced current capacity (50mA versus 150mA) and lower voltage rating (24VDC versus 30VDC). Applications requiring the full 150mA rating or 30VDC operation cannot use this part. Additionally, the slide actuator differs from the rocker actuator, requiring mechanical design verification for panel mounting and user interface compatibility.

Q: Does the 76SB02T meet modern regulatory requirements?

A: Yes. The 76SB02T is ROHS3 compliant, addressing environmental and regulatory requirements that the obsolete 76SB02 does not meet. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The 76SB02 is supplied in bulk packaging, while both the 76SB02T and 206-2 are supplied in tube packaging. Tube packaging provides improved component protection and handling efficiency for production environments.

Q: What is the mechanical life difference between the 76SB02 and 206-2?

A: The 76SB02 specifies 2,000 mechanical cycles. The 206-2 does not provide a mechanical life specification. However, the 206-2 offers 10,000 electrical cycles compared to 2,000 cycles for the 76SB02, indicating potentially different design characteristics and application suitability.

Q: Can the 76SB02T be used in applications originally designed for the 76SB02?

A: Yes. The 76SB02T maintains full backward compatibility with the 76SB02 across all critical parameters: SPST configuration, 2-position operation, 150mA current rating, 30VDC voltage rating, rocker actuator, through-hole mounting, 0.100" pitch, and identical physical dimensions. The primary advantage is active production status and ROHS3 compliance.
