Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76RGB04ST is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 76RSB04ST maintains identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SPST), number of positions (4), current rating (150mA), and voltage rating (30VDC) are identical.

Mechanical Parameters: Actuator type (rocker), mounting method (through hole), termination style (PC pin), pitch (0.100"), and height above board (0.292") are identical.

Material & Environmental: 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) are identical.

Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity).

The primary distinction between the main part and substitute is product status and packaging. The 76RGB04ST is obsolete, while the 76RSB04ST is active. The 76RSB04ST is supplied in tube packaging, whereas the 76RGB04ST packaging is not specified.

Parameter Comparison

Engineering Selection Recommendations

The 76RSB04ST is the direct functional equivalent of the 76RGB04ST. Selection of the 76RSB04ST is appropriate for applications requiring the 76RGB04ST, as all electrical, mechanical, and environmental specifications are identical.

The 76RSB04ST carries active product status, ensuring ongoing manufacturer support and supply chain availability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current design standards.

The tube packaging of the 76RSB04ST is standard for component distribution and does not affect electrical or mechanical performance. Procurement of the 76RSB04ST eliminates obsolescence risk associated with the 76RGB04ST.
