Grayhill 76MSB05S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76MSB05S is a single-pole single-throw (SPST) DIP switch with 5 positions, rated for 150mA at 30VDC. This component features a rocker actuator with raised level, gold-plated copper alloy contacts, and through-hole PC pin termination. The 76MSB05S is classified as obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and contact specifications to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76MSB05S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-Negotiable):

• Circuit configuration: SPST
• Number of positions: 5
• Current rating: 150mA minimum
• Voltage rating: 30VDC minimum
• Contact material and finish: Copper alloy with gold plating

Mechanical Parameters (Non-Negotiable):

• Actuator type: Rocker with raised level
• Mounting type: Through hole
• Termination style: PC pin
• Pitch: 0.100" (2.54mm)
• Height above board: 0.315" (8.00mm)
• Length: 0.580" (14.73mm)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to +85°C minimum
• Mechanical and electrical life: 2,000 cycles minimum
• RoHS3 compliance required
• MSL rating: 1 (Unlimited) acceptable

The 76SB05ST meets all substitution criteria and is identified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 76SB05ST is a direct functional equivalent to the obsolete 76MSB05S. Both components are manufactured by Grayhill Inc. within the same 76 series and share identical electrical ratings, mechanical dimensions, contact specifications, and environmental operating parameters.

Primary Recommendation: The 76SB05ST is the preferred substitute for the 76MSB05S. The substitute maintains active product status with Grayhill Inc., ensuring ongoing availability and manufacturing support. All critical electrical and mechanical parameters are identical, confirming pin-for-pin and functional compatibility.

Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, satisfying regulatory requirements for current manufacturing standards.

Packaging Consideration: The primary difference between the two parts is packaging format. The 76MSB05S is supplied with tape seal packaging, while the 76SB05ST is supplied in tube packaging. This distinction affects only procurement and handling procedures and does not impact electrical or mechanical performance in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the 76SB05ST directly replace the 76MSB05S in existing designs?

A: Yes. The 76SB05ST is a direct functional equivalent with identical electrical ratings (150mA, 30VDC), circuit configuration (SPST, 5 positions), mechanical dimensions (0.315" height, 0.580" length, 0.100" pitch), and contact specifications (copper alloy with gold finish). Pin-for-pin compatibility is confirmed.

Q: What is the difference between the 76MSB05S and 76SB05ST?

A: The components are electrically and mechanically identical. The primary difference is product status and packaging. The 76MSB05S is obsolete with tape seal packaging, while the 76SB05ST is an active product supplied in tube packaging. Both are manufactured by Grayhill Inc. within the 76 series.

Q: Does packaging format affect component performance?

A: No. Packaging format (tape seal versus tube) affects only procurement, storage, and handling procedures. Electrical performance, mechanical specifications, and reliability characteristics remain identical regardless of packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 76MSB05S and 76SB05ST are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory requirements.

Q: What is the operating temperature range for these components?

A: Both parts operate across -40°C to +85°C, with identical mechanical and electrical life ratings of 2,000 cycles.

Q: Why is the 76MSB05S listed as obsolete?

A: The 76MSB05S has been discontinued by Grayhill Inc. The 76SB05ST remains in active production as the current equivalent offering within the 76 series DIP switch product line.
