76MPSB08S DIP Switch Piano Actuator Equivalent & Substitute Parts

Part Overview

The 76MPSB08S is an 8-position DIP switch manufactured by Grayhill Inc., featuring a piano actuator mechanism with SPST (Single Pole Single Throw) circuit configuration. This component is rated for 150mA at 30VDC and is designed for through-hole, right-angle mounting applications. The part is currently classified as obsolete, making identification of active equivalent substitutes essential for ongoing production and maintenance requirements. The 76MPSB08S maintains full electrical and mechanical compatibility with active alternatives within the Grayhill 76 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76MPSB08S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 76PSB08ST maintains identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SPST), number of positions (8), current rating (150mA), and voltage rating (30VDC) are identical between the main part and substitute.

Mechanical Parameters: Actuator type (piano, raised level), mounting configuration (through-hole, right-angle), pitch (0.100" / 2.54mm), and height above board (0.301" / 7.65mm) are fully matched.

Environmental & Compliance: Operating temperature range (-40°C to 85°C), contact material (copper alloy with gold finish), RoHS3 compliance, MSL rating (1), and REACH status are equivalent across both parts.

Distinguishing Factor: The primary difference between 76MPSB08S and 76PSB08ST is product status and packaging. The 76MPSB08S is obsolete with tape seal packaging, while 76PSB08ST is active with tube packaging. This substitution is valid for all applications where the 76MPSB08S was previously specified.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB08ST is the direct active equivalent for the obsolete 76MPSB08S. Selection of the 76PSB08ST is based on the following engineering criteria:

Product Status: The 76MPSB08S is classified as obsolete. The 76PSB08ST maintains active product status with Grayhill Inc., ensuring continued availability and manufacturer support.

Electrical Equivalence: All electrical parameters are identical, including circuit configuration, position count, current and voltage ratings. The parts are electrically interchangeable without circuit modification.

Mechanical Equivalence: Mounting configuration, pitch, height, and actuator characteristics are fully matched. PCB layout and mechanical integration require no redesign.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status. MSL rating of 1 (unlimited) applies to both parts, indicating no moisture sensitivity constraints.

Packaging Consideration: The 76PSB08ST is supplied in tube packaging, whereas the 76MPSB08S used tape seal packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB08ST be used as a direct replacement for the 76MPSB08S in existing designs?

A: Yes. The 76PSB08ST is electrically and mechanically equivalent to the 76MPSB08S across all specified parameters. No circuit modifications or PCB redesign is required. The parts are pin-compatible and functionally identical.

Q: What is the primary reason for substituting the 76MPSB08S?

A: The 76MPSB08S is classified as obsolete. The 76PSB08ST is the active equivalent from Grayhill Inc. and provides continued component availability for new production and field replacement applications.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts are rated for 150mA at 30VDC with SPST configuration and 8 positions. Operating temperature range, mechanical life, and electrical life specifications are identical.

Q: How does the packaging difference affect component selection?

A: The 76MPSB08S uses tape seal packaging while the 76PSB08ST uses tube packaging. This affects receiving, storage, and handling procedures but does not impact electrical or mechanical performance. Tube packaging is standard for active production parts.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 76MPSB08S and 76PSB08ST are ROHS3 compliant and REACH unaffected. MSL rating of 1 (unlimited) applies to both parts.

Q: What is the pitch specification for these DIP switches?

A: Both parts feature a pitch of 0.100" (2.54mm), which is the standard spacing for 8-position DIP switches. This ensures compatibility with standard DIP switch footprints on PCBs.

Q: Can these parts be used in high-temperature applications?

A: Both parts are rated for operation from -40°C to 85°C. Applications requiring operation outside this range require alternative component selection.
