Key Parameters

Substitute Part Grouping Explanation

Substitution of the M83504/01-024 is determined by strict equivalence across the following critical parameters:

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

Mechanical Parameters: Actuator type (rocker), actuator level (raised), mounting type (through hole), termination style (PC pin), and pitch (0.100" / 2.54mm) must match exactly.

Physical Dimensions: Height above board (0.315" / 8.00mm) and length (0.480" / 12.19mm) must be preserved for PCB layout compatibility.

Contact Specifications: Contact material (copper alloy) and contact finish (gold) ensure electrical performance and reliability equivalence.

Environmental Specifications: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) must be maintained.

The substitute part 76SB04ST meets all these criteria and is identified as an active product within the same Grayhill 76 series.
