Grayhill 76MPSB10S DIP Switch - Equivalent & Substitute Parts

Part Overview

The Grayhill 76MPSB10S is a 10-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, gold-plated copper alloy contacts, and through-hole right-angle mounting. The 76MPSB10S is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and functional characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76MPSB10S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters: Circuit type (SPST), number of positions (10), current rating (150mA minimum), and voltage rating (30VDC minimum) must be identical or exceed the original specification.

Mechanical Parameters: Actuator type (piano), actuator level (raised), contact material (copper alloy with gold finish), mounting configuration (through-hole, right-angle), pitch (0.100"), and height above board (0.301") must match exactly.

Environmental & Compliance Parameters: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), electrical life (2,000 cycles), RoHS3 compliance, and MSL rating (1) must be maintained.

Packaging Consideration: The main part 76MPSB10S is supplied in tape seal packaging. The substitute part 76PSB10ST is supplied in tube packaging. Both packaging formats are acceptable for equivalent substitution provided all other parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB10ST is a direct functional equivalent to the obsolete 76MPSB10S. All electrical parameters, mechanical dimensions, contact specifications, and environmental ratings are identical. Both components are manufactured by Grayhill Inc. within the 76 series and maintain full ROHS3 compliance and REACH unaffected status.

The primary distinction is product status: the 76MPSB10S is obsolete, while the 76PSB10ST is active and currently in production. The 76PSB10ST is supplied in tube packaging rather than tape seal packaging; however, this represents a packaging format difference only and does not affect functional compatibility or performance characteristics.

For applications currently using the 76MPSB10S, transition to the 76PSB10ST is supported without design modification. The substitute part maintains identical pinout, electrical performance, mechanical fit, and environmental specifications. No circuit redesign, PCB layout modification, or functional testing beyond standard component verification is required.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB10ST directly replace the 76MPSB10S in existing designs?

A: Yes. The 76PSB10ST is a direct functional equivalent. All electrical ratings (150mA, 30VDC, SPST 10-position), mechanical dimensions (0.301" height, 0.100" pitch, 1.080" length), contact specifications (copper alloy, gold finish), and mounting configuration (through-hole, right-angle) are identical. No design changes are required.

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

A: Tape seal and tube packaging are alternative delivery formats for the same component. Tape seal packaging uses adhesive tape to secure components in a reel format, while tube packaging uses a plastic tube container. Both formats contain identical components with identical specifications. Selection between packaging formats depends on assembly equipment compatibility and inventory management requirements.

Q: Are the operating temperature ranges identical?

A: Yes. Both the 76MPSB10S and 76PSB10ST operate across the identical temperature range of -40°C to 85°C. Mechanical life and electrical life specifications (2,000 cycles each) are also identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL rating (1, Unlimited). Compliance certifications and regulatory status are equivalent.

Q: Why is the 76MPSB10S listed as obsolete?

A: The 76MPSB10S has been discontinued by the manufacturer. The 76PSB10ST is the active production equivalent. For new designs and ongoing procurement, the 76PSB10ST should be specified.

Q: Are there any electrical performance differences between the two parts?

A: No. Current rating (150mA), voltage rating (30VDC), circuit configuration (SPST), number of positions (10), contact material (copper alloy with gold finish), and all electrical life specifications (2,000 cycles) are identical.
