Electrical and Mechanical Equivalence: All critical parameters—circuit configuration, current and voltage ratings, actuator type, mounting configuration, contact materials, and lifecycle ratings—are identical between the two parts.

Supply Chain Availability: The 90B08ST has significantly higher inventory availability (6,198 pieces) compared to the M83504/12-008 (898 pieces), supporting production continuity.

The 90B08ST is suitable for direct substitution in applications currently utilizing the M83504/12-008, provided that RoHS compliance requirements are compatible with the design specification.

Frequently Asked Questions (FAQ)

Q: Can the 90B08ST be used as a direct replacement for the M83504/12-008?

A: Yes. The 90B08ST is electrically and mechanically equivalent to the M83504/12-008. All critical parameters—including circuit configuration (SPST), number of positions (8), current rating (25mA), voltage rating (24VDC), actuator type (slide, standard), mounting type (through hole), pitch (0.100"), and lifecycle ratings (2,000 cycles)—are identical.

Q: What is the difference between the M83504/12-008 and the 90B08ST?

A: The primary differences are product status and regulatory compliance. The M83504/12-008 is obsolete and RoHS non-compliant, while the 90B08ST is active and ROHS3 compliant. All functional and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The M83504/12-008 is supplied with tape seal packaging, while the 90B08ST is supplied in tube packaging. Both packaging formats are suitable for through-hole component handling and storage.

Q: Will the 90B08ST fit in the same PCB footprint as the M83504/12-008?

A: Yes. Both parts have identical mounting specifications: through-hole mounting, 0.100" (2.54mm) pitch, 0.195" (4.95mm) height above board, and 0.870" (22.10mm) length. No PCB redesign is required.

Q: Is the 90B08ST suitable for applications with RoHS compliance requirements?

A: Yes. The 90B08ST is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The M83504/12-008 is RoHS non-compliant and should not be used in RoHS-restricted applications.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts are rated for 25mA at 24VDC, feature SPST switching with 8 positions, and are rated for 2,000 mechanical and electrical cycles. Operating temperature range (-40°C to 85°C) and contact materials (gold-plated copper alloy) are identical.
