Grayhill 76RGB02ST DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76RGB02ST 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 functionally equivalent alternatives essential for ongoing system support and procurement planning. The 76RGB02ST features a through-hole mounting design with gold-plated copper alloy contacts, flush rocker actuator, and washable construction suitable for industrial control and instrumentation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76RGB02ST 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 electrical load-carrying capability and switching function.

Mechanical Parameters: Actuator type (rocker), mounting method (through hole), pitch spacing (0.100"), and height above board (0.292") must match to ensure physical compatibility with existing PCB layouts and enclosure designs.

Material and Environmental Parameters: Contact material (copper alloy), contact finish (gold), operating temperature range (-40°C to 85°C), and washable construction must be maintained for reliability and process compatibility.

Lifecycle Parameters: Mechanical and electrical life ratings (2,000 cycles each) establish the expected operational durability.

The 76RSB02ST meets all these criteria and is identified as the direct substitute for the obsolete 76RGB02ST.

Parameter Comparison

Engineering Selection Recommendations

The 76RSB02ST is the direct functional equivalent of the 76RGB02ST across all critical electrical, mechanical, and environmental parameters. The substitute part maintains identical performance specifications while offering the advantage of active product status, ensuring long-term availability and supply chain continuity.

Compliance Considerations: The 76RSB02ST carries ROHS3 compliance, which supersedes the RoHS compliance of the 76RGB02ST. Both parts maintain REACH Unaffected and EAR99 export classification status. The upgrade to ROHS3 compliance represents an improvement in regulatory alignment with current environmental standards.

Packaging Difference: The primary distinction between the two parts is packaging format. The 76RGB02ST is supplied in tape packaging, while the 76RSB02ST is supplied in tube packaging. This difference does not affect electrical or mechanical performance and relates only to component handling and storage logistics.

Availability: The 76RSB02ST is currently in active production with substantial inventory availability (4,951 pieces), compared to the obsolete 76RGB02ST (849 pieces remaining). Selection of the 76RSB02ST ensures access to current manufacturing and future supply security.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB02ST be used as a direct replacement for the 76RGB02ST in existing designs?

A: Yes. The 76RSB02ST is electrically and mechanically identical to the 76RGB02ST across all functional parameters. Both parts feature identical SPST configuration, 150mA/30VDC ratings, rocker actuator design, through-hole mounting, 0.100" pitch, and operating temperature range. Direct substitution on PCBs is supported without design modification.

Q: What is the difference between tape and tube packaging?

A: Tape packaging uses a continuous carrier tape with individual components spaced at regular intervals, typically used for automated assembly processes. Tube packaging places components in a cylindrical container, commonly used for manual assembly or lower-volume applications. Both packaging formats contain identical components with no performance difference.

Q: Are there any compliance or regulatory differences between the two parts?

A: The 76RSB02ST carries ROHS3 compliance, which is the current regulatory standard, while the 76RGB02ST carries RoHS compliance. ROHS3 represents an updated compliance framework. Both parts maintain identical REACH Unaffected status and EAR99 export classification. The upgrade to ROHS3 is compatible with systems designed for RoHS compliance.

Q: Why is the 76RGB02ST listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand, production efficiency, or product line consolidation. The 76RSB02ST serves as the active replacement, maintaining all functional specifications while offering current manufacturing support.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (SPST), electrical ratings (150mA/30VDC), actuator type (rocker), mounting method (through hole), pitch spacing (0.100"), height above board (0.292"), contact material and finish (copper alloy with gold), operating temperature range (-40°C to 85°C), and mechanical/electrical life ratings (2,000 cycles each).

Q: Can the 76RSB02ST handle the same electrical loads as the 76RGB02ST?

A: Yes. Both parts are rated identically at 150mA continuous current and 30VDC maximum voltage. Electrical load capacity is equivalent across all specified operating conditions.

Q: What is the mechanical life expectancy of the 76RSB02ST?

A: The 76RSB02ST is rated for 2,000 mechanical cycles and 2,000 electrical cycles, identical to the 76RGB02ST. This rating defines the expected operational life under normal switching conditions.
