Key Parameters

Substitute Part Grouping Explanation

Substitution of the M83504/01-025 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute, model 76SB05ST, maintains identical specifications in the following critical areas:

Electrical Parameters: Circuit configuration (SPST), number of positions (5), current rating (150mA), and voltage rating (30VDC) are identical between the main part and substitute.

Mechanical Parameters: Actuator type (rocker), actuator level (raised), contact material (copper alloy), contact finish (gold), mounting type (through hole), termination style (PC pin), pitch (0.100"), and height above board (0.315") are fully matched.

Environmental Parameters: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) are equivalent.

Key Differentiators: The primary distinction between M83504/01-025 and 76SB05ST is product status and regulatory compliance. The M83504/01-025 is obsolete and RoHS non-compliant, while 76SB05ST is active and ROHS3 compliant. Packaging differs (M83504/01-025 uses standard packaging; 76SB05ST uses tube packaging).

Parameter Comparison

Engineering Selection Recommendations

The 76SB05ST is the direct functional equivalent to the obsolete M83504/01-025. Selection of 76SB05ST is appropriate for the following reasons:

Product Status: The 76SB05ST maintains active product status with Grayhill Inc., ensuring continued availability and manufacturer support. The M83504/01-025 is obsolete and subject to discontinuation without notice.

Regulatory Compliance: The 76SB05ST is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The M83504/01-025 is RoHS non-compliant and may not satisfy procurement requirements for new designs or applications subject to RoHS directives.

Electrical and Mechanical Equivalence: All functional parameters are identical, ensuring direct substitution without circuit redesign or PCB layout modification.

Packaging Consideration: The 76SB05ST is supplied in tube packaging, which may differ from original procurement specifications. Verify packaging requirements with procurement and assembly operations before finalizing component selection.

Frequently Asked Questions (FAQ)

Q: Can 76SB05ST be used as a direct replacement for M83504/01-025 in existing designs?
