76MSB10S DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The 76MSB10S is a 10-position DIP switch with rocker actuator manufactured by Grayhill Inc. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement. The switch is rated for 150mA at 30VDC and features through-hole mounting with gold-plated copper alloy contacts suitable for washable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76MSB10S is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (10), current rating (150mA), and voltage rating (30VDC) must remain identical.

Mechanical Parameters: Actuator type (rocker), actuator level (raised), mounting type (through hole), termination style (PC pin), and pitch (0.100" / 2.54mm) must match exactly.

Physical Dimensions: Height above board (0.315" / 8.00mm) and length (1.080" / 27.43mm) must be preserved for PCB layout compatibility.

Material & Environmental Specifications: Contact material (copper alloy), contact finish (gold), body material (thermoplastic), operating temperature range (-40°C to 85°C), and washable feature must be maintained.

Compliance Requirements: RoHS3 compliance and MSL rating 1 must be retained.

The 76SB10ST meets all these criteria and serves as the direct substitute for the obsolete 76MSB10S.

Parameter Comparison

Engineering Selection Recommendations

The 76SB10ST is the direct functional equivalent of the 76MSB10S. All electrical, mechanical, and dimensional parameters are identical. The primary distinction is product status: the 76MSB10S is obsolete while the 76SB10ST is active, making the latter the appropriate selection for new designs and ongoing procurement.

Both parts maintain ROHS3 compliance and carry identical environmental certifications (REACH unaffected, ECCN EAR99, HTSUS 8536.50.9065). The packaging differs between the two parts (tape seal versus tube), which may affect procurement logistics but does not impact functional performance or PCB integration.

For applications currently using the 76MSB10S, direct substitution with the 76SB10ST requires no circuit redesign, PCB layout modification, or firmware changes. The parts are pin-compatible and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the 76SB10ST replace the 76MSB10S in existing designs?

A: Yes. The 76SB10ST is functionally identical to the 76MSB10S across all electrical, mechanical, and dimensional specifications. No circuit modifications are required.

Q: What is the difference between the 76MSB10S and 76SB10ST?

A: The primary difference is product status and packaging. The 76MSB10S is obsolete and supplied in tape seal packaging. The 76SB10ST is active and supplied in tube packaging. All functional parameters are identical.

Q: Are there any PCB layout considerations when switching from 76MSB10S to 76SB10ST?

A: No. Both parts share identical mounting type (through hole), pitch (0.100" / 2.54mm), height above board (0.315" / 8.00mm), and length (1.080" / 27.43mm). PCB footprints are directly compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 76MSB10S and 76SB10ST are ROHS3 compliant, carry MSL rating 1 (unlimited), and share identical REACH and ECCN classifications.

Q: What is the difference in packaging between these parts?

A: The 76MSB10S is supplied in tape seal packaging, while the 76SB10ST is supplied in tube packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 150mA at 30VDC with SPST circuit configuration and 10 positions. Operating temperature range, mechanical life, and electrical life specifications are identical.
