Grayhill 76MPBS06S DIP Switch Equivalent & Substitute Parts
Part Overview
The Grayhill 76MPBS06S is a 6-position DIP switch with SPST (Single Pole Single Throw) circuit configuration, rated for 150mA at 30VDC. This component features a piano-style actuator with raised level, through-hole right-angle mounting, and gold-plated copper alloy contacts. The 76MPBS06S is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing production and design continuity.

Substitute Part Grouping Explanation
Substitution of the obsolete 76MPBS06S is based on strict electrical and mechanical parameter matching within the Grayhill 76 series. The substitute part must satisfy all of the following criteria:
- Identical circuit configuration (SPST)
- Identical number of positions (6)
- Identical current rating (150mA)
- Identical voltage rating (30VDC)
- Identical actuator type and level (Piano, Raised)
- Identical mounting configuration (Through Hole, Right Angle)
- Identical contact material and finish (Copper Alloy, Gold)
- Identical pitch spacing (0.100" / 2.54mm)
- Identical operating temperature range (-40°C to 85°C)
- Identical mechanical and electrical life ratings (2,000 Cycles)
- Compliance with RoHS3 and REACH requirements
The 76PSB06ST meets all substitution criteria and is classified as an active product with current manufacturing status.

Engineering Selection Recommendations
The 76PSB06ST is the direct functional equivalent for the obsolete 76MPBS06S. All electrical specifications, mechanical dimensions, contact characteristics, and environmental ratings are identical. The primary distinction is product status: the 76MPBS06S is obsolete while the 76PSB06ST is an active product with current manufacturing availability.
Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity. The 76PSB06ST is supplied in tube packaging, whereas the 76MPBS06S was supplied with tape seal packaging. This packaging difference does not affect electrical or mechanical performance and is a standard variation in component distribution.
For applications currently using the 76MPBS06S, direct substitution with the 76PSB06ST is supported by complete parameter equivalence. No circuit redesign, PCB layout modification, or functional revalidation is required.
Frequently Asked Questions (FAQ)
Q: Can the 76PSB06ST replace the 76MPBS06S in existing designs?
A: Yes. The 76PSB06ST is electrically and mechanically identical to the 76MPBS06S across all specified parameters. Direct substitution is supported without design changes.
Q: What is the difference between tape seal and tube packaging?
A: Tape seal and tube packaging are distribution formats only. Both protect the component during storage and handling. The electrical and mechanical performance of the DIP switch is identical regardless of packaging type.
Q: Are there any compliance differences between these parts?
A: No. Both the 76MPBS06S and 76PSB06ST are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.
Q: Why is the 76MPBS06S classified as obsolete?
A: Obsolescence is a product lifecycle status assigned by the manufacturer. The 76PSB06ST represents the active equivalent within the Grayhill 76 series and is the recommended source for new procurement.
Q: Are the mechanical dimensions identical?
A: Yes. Both parts share identical height above board (0.301" / 7.65mm), length (0.680" / 17.27mm), and pitch spacing (0.100" / 2.54mm). PCB footprints are interchangeable.
Q: What is the contact life rating for these switches?
A: Both parts are rated for 2,000 mechanical cycles and 2,000 electrical cycles under specified operating conditions.
Q: Can these switches be used in washable applications?
A: Yes. Both the 76MPBS06S and 76PSB06ST are rated as washable components.
