Grayhill 76MPSB02S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76MPSB02S is a piano-actuated DIP switch designed for through-hole, right-angle mounting applications. This SPST (Single Pole Single Throw) switch is rated for 150mA at 30VDC and features a 2-position configuration with gold-plated copper alloy contacts. The 76MPSB02S is classified as obsolete, making identification of active equivalent parts essential for ongoing production support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76MPSB02S is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Circuit configuration: SPST
• Number of positions: 2
• Current rating: 150mA
• Voltage rating: 30VDC
• Actuator type: Piano with raised level
• Mounting configuration: Through hole, right angle
• Contact material and finish: Copper alloy with gold plating
• Pitch spacing: 0.100" (2.54mm)
• Height above board: 0.301" (7.65mm)
• Operating temperature range: -40°C to 85°C
• Mechanical and electrical life: 2,000 cycles minimum

The 76PSB02ST meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB02ST is the direct functional equivalent to the obsolete 76MPSB02S. Both parts are manufactured by Grayhill Inc. within the 76 series and share identical electrical ratings, mechanical dimensions, and contact specifications.

Selection Basis:

The 76PSB02ST is recommended for new designs and production replacement of the 76MPSB02S based on:

• Identical electrical performance: 150mA at 30VDC SPST configuration
• Identical mechanical compatibility: Through-hole right-angle mounting with 0.100" pitch and 0.301" height
• Identical contact specifications: Copper alloy with gold plating
• Identical operating range: -40°C to 85°C
• Identical lifecycle ratings: 2,000 mechanical and electrical cycles
• Active product status: 76PSB02ST is currently in production with 5,454 units in stock
• Equivalent compliance: Both parts are ROHS3 compliant and REACH unaffected

The only differences are packaging format (tube versus tape seal) and product lifecycle status. These differences do not affect functional performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB02ST directly replace the 76MPSB02S in existing designs?

A: Yes. The 76PSB02ST is electrically and mechanically identical to the 76MPSB02S. All electrical ratings, mechanical dimensions, contact materials, and operating parameters are equivalent. No circuit modifications or PCB layout changes are required.

Q: What is the difference between the tape seal and tube packaging?

A: Tape seal and tube packaging are different handling and storage formats. Tape seal packaging uses adhesive tape for component retention, while tube packaging uses a plastic tube. Both formats contain the same component with identical specifications. Packaging selection depends on assembly equipment compatibility and inventory management requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 76MPSB02S and 76PSB02ST carry identical RoHS3 compliance and REACH unaffected status. Both parts meet the same environmental and regulatory standards.

Q: Why is the 76MPSB02S listed as obsolete?

A: The 76MPSB02S has been discontinued by Grayhill Inc. The 76PSB02ST is the active production equivalent. For ongoing procurement and new designs, the 76PSB02ST should be specified.

Q: Are the mechanical life and electrical life ratings the same?

A: Yes. Both parts are rated for 2,000 mechanical cycles and 2,000 electrical cycles, indicating identical durability and switching performance characteristics.

Q: What is the pitch specification and why does it matter?

A: Both parts have a 0.100" (2.54mm) pitch, which is the center-to-center spacing between switch positions. This standard pitch ensures compatibility with standard DIP switch footprints and PCB layouts designed for Grayhill 76 series switches.
