Key Parameters

Substitute Part Grouping Explanation

The 76MSB02S and its substitute 76SB02ST are functionally equivalent based on the following critical parameters that determine substitutability:

Electrical Parameters: Both parts maintain identical SPST circuit configuration, 2-position switching, 150mA current rating, and 30VDC voltage rating. Contact material (copper alloy with gold finish) and electrical life (2,000 cycles) are identical.

Mechanical Parameters: Both employ rocker actuators with raised actuation level, through-hole mounting, 0.100" pitch, and 0.315" height above board. Mechanical life specification is identical at 2,000 cycles.

Environmental Parameters: Operating temperature range (-40°C to +85°C), body material (thermoplastic), and washable design are identical across both parts.

Compliance Parameters: Both parts carry ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications.

The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 76SB02ST is the direct active equivalent for the obsolete 76MSB02S. Selection of the 76SB02ST is appropriate for all applications currently utilizing the 76MSB02S, as all electrical, mechanical, and environmental specifications are identical.

Product Status Consideration: The 76MSB02S is classified as obsolete. The 76SB02ST maintains active product status with Grayhill Inc., ensuring continued availability, technical support, and manufacturing consistency.

Compliance Alignment: Both parts carry identical ROHS3 compliance certification and REACH unaffected status, maintaining regulatory alignment for new designs and legacy system support.

Packaging Difference: The 76MSB02S is supplied in tape seal packaging, while the 76SB02ST is supplied in tube packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance in the application.

Frequently Asked Questions (FAQ)

Q: Can the 76SB02ST directly replace the 76MSB02S in existing designs?

A: Yes. The 76SB02ST is electrically and mechanically identical to the 76MSB02S. All switching characteristics, current and voltage ratings, actuator geometry, and mounting specifications are equivalent. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The 76MSB02S is obsolete, indicating Grayhill Inc. has discontinued active manufacturing and support. The 76SB02ST is active, ensuring ongoing availability, consistent manufacturing quality, and technical support. For new designs or legacy system refreshes, the 76SB02ST is the recommended selection.

Q: How do the packaging differences affect component selection?

A: The 76MSB02S uses tape seal packaging while the 76SB02ST uses tube packaging. This affects procurement quantities, storage, and automated assembly compatibility. Tape seal packaging is typically used for high-volume automated placement, while tube packaging is common for manual assembly or lower-volume applications. Verify packaging compatibility with your assembly process before procurement.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts specify 150mA current rating at 30VDC, SPST configuration with 2 positions, 2,000-cycle mechanical and electrical life, and identical contact material (copper alloy with gold finish). Operating temperature range (-40°C to +85°C) is identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 76MSB02S and 76SB02ST carry ROHS3 compliance certification, REACH unaffected status, and identical ECCN/HTSUS classifications. Regulatory requirements are satisfied by either part.

Q: What determines whether a part can substitute for the 76MSB02S?

A: Substitution is determined by matching the following parameters: SPST circuit configuration, 2-position switching, 150mA current rating, 30VDC voltage rating, rocker actuator with raised level, through-hole mounting, 0.100" pitch, 0.315" height above board, copper alloy gold-finish contacts, -40°C to +85°C operating temperature, and 2,000-cycle mechanical/electrical life. The 76SB02ST meets all these criteria.
