Grayhill 76RGB02T DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76RGB02T is a DIP switch rocker actuator with SPST (Single Pole Single Throw) configuration, rated for 150mA at 30VDC. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and component procurement. The 76RGB02T features a through-hole mounting design with flush rocker actuator and gold-plated copper alloy contacts suitable for applications requiring reliable switching in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 76RGB02T is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (2), current rating (150mA), and voltage rating (30VDC) must be identical. These parameters define the functional switching capability and load-handling capacity.

Mechanical Parameters: Actuator type (rocker), actuator level (flush/recessed), mounting type (through hole), termination style (PC pin), and pitch (0.100" / 2.54mm) must match to ensure physical and electrical compatibility with existing PCB layouts and mechanical assemblies.

Material & Environmental Parameters: Contact material (copper alloy), contact finish (gold), operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) establish performance consistency and reliability expectations.

Compliance Parameters: RoHS compliance status and MSL rating (1 - Unlimited) ensure regulatory and environmental compatibility.

The Grayhill 76RSB02T meets all these criteria and is identified as a direct substitute for the obsolete 76RGB02T.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 76RSB02T is the direct equivalent substitute for the obsolete Grayhill 76RGB02T. Both components share identical electrical, mechanical, and environmental specifications across all critical parameters. The primary distinction is product status: the 76RGB02T is obsolete while the 76RSB02T maintains active production status.

From a compliance perspective, both parts are RoHS compliant. The 76RSB02T carries ROHS3 certification, representing current regulatory alignment. Both components are REACH unaffected and carry identical ECCN (EAR99) and HTSUS classifications.

The packaging difference between the two parts (76RGB02T supplied in standard packaging versus 76RSB02T supplied in tube packaging) does not affect functional or mechanical compatibility. This distinction is relevant only for procurement and inventory management.

For new designs or component replacement in existing systems, the 76RSB02T should be selected as the active production equivalent. The identical parameter set ensures drop-in compatibility without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB02T directly replace the 76RGB02T without PCB modification?

A: Yes. The 76RSB02T is electrically and mechanically identical to the 76RGB02T. All critical parameters including pitch (0.100" / 2.54mm), height above board (0.292" / 7.41mm), and termination style (PC pin) are identical. No PCB layout changes are required.

Q: What is the difference between the 76RGB02T and 76RSB02T?

A: The primary differences are product status and packaging. The 76RGB02T is obsolete; the 76RSB02T is in active production. The 76RGB02T uses standard packaging while the 76RSB02T uses tube packaging. All electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. The 76RGB02T is RoHS compliant. The 76RSB02T is ROHS3 compliant, representing current regulatory standards. Both meet RoHS requirements.

Q: What are the key electrical specifications for these switches?

A: Both the 76RGB02T and 76RSB02T are rated for 150mA at 30VDC with SPST (Single Pole Single Throw) configuration. Operating temperature range is -40°C to 85°C. Mechanical and electrical life are both rated at 2,000 cycles.

Q: Can these switches be used in applications requiring higher current or voltage?

A: No. These components are rated for maximum 150mA at 30VDC. Use in applications exceeding these ratings will result in component failure and potential safety hazards.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.100" (2.54mm), which is the standard spacing between PC pins. This specification is critical for PCB compatibility and ensures proper alignment with through-hole mounting positions.

Q: Are these components washable?

A: No. Both the 76RGB02T and 76RSB02T are not washable. Standard PCB cleaning procedures should account for this limitation.

Q: What is the MSL rating and what does it mean?

A: Both components carry MSL (Moisture Sensitivity Level) rating of 1, which indicates unlimited shelf life with no special moisture control requirements during storage or handling.
