Grayhill 76SB12 DIP Switch Rocker SPST 150mA 30V Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB12 is a 12-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting applications. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The 76SB12 series provides SPST (Single Pole Single Throw) switching functionality with gold-plated copper alloy contacts suitable for general-purpose switching applications in industrial and commercial electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 76SB12 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST
• Number of positions: 12
• Current rating: 150mA minimum
• Voltage rating: 30VDC minimum
• Actuator type: Rocker with raised level
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Height above board: 0.315" (8.00mm)
• Contact material and finish: Copper alloy with gold plating
• Operating temperature range: -40°C to +85°C minimum
• Mechanical and electrical life: 2,000 cycles minimum

The Grayhill 76SB12T meets all mandatory parameters and qualifies as a direct functional equivalent. The primary distinction between the main part and its substitute is product status and RoHS compliance level, not electrical or mechanical performance.

Engineering Selection Recommendations

For New Designs and Procurement:

The Grayhill 76SB12T is the recommended selection for all new applications and ongoing procurement. This part maintains complete electrical and mechanical equivalence to the 76SB12 while offering the following advantages:

• Active Product Status: The 76SB12T is an active product with ongoing manufacturer support and availability assurance, eliminating supply chain risk associated with obsolete components.
• RoHS3 Compliance: The 76SB12T meets RoHS3 requirements, satisfying regulatory compliance mandates for products destined for EU markets and applications subject to RoHS directives.
• Standardized Packaging: Tube packaging provides improved component protection and handling efficiency compared to bulk packaging.

For Legacy System Maintenance:

If the 76SB12 is currently deployed in production systems, the 76SB12T provides direct functional replacement without circuit redesign or PCB layout modification. Pin-for-pin compatibility and identical electrical ratings ensure drop-in substitution capability.

Frequently Asked Questions (FAQ)

Q: Can the 76SB12T be used as a direct replacement for the 76SB12 in existing designs?

A: Yes. The 76SB12T is electrically and mechanically identical to the 76SB12. Both components feature identical SPST switching configuration, 12-position rocker actuator, 150mA current rating, 30VDC voltage rating, through-hole mounting with 0.100" pitch, and -40°C to +85°C operating temperature range. No circuit modifications or PCB layout changes are required.

Q: What is the primary reason for substituting the 76SB12 with the 76SB12T?

A: The 76SB12 is classified as obsolete, creating procurement and supply chain risk. The 76SB12T is an active product from the same manufacturer with identical electrical and mechanical specifications, ensuring long-term availability and design continuity.

Q: Does the RoHS compliance difference affect component performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical or mechanical performance. Both the 76SB12 and 76SB12T deliver identical switching performance and reliability characteristics. RoHS3 compliance of the 76SB12T is advantageous for regulatory adherence in new product development.

Q: Are there packaging considerations when switching from 76SB12 to 76SB12T?

A: The 76SB12 is supplied in bulk packaging, while the 76SB12T is supplied in tube packaging. Tube packaging provides improved component protection during storage and handling. No functional or performance differences result from this packaging distinction.

Q: What are the critical parameters that define substitution eligibility for this DIP switch series?

A: Substitution eligibility is determined by equivalence in circuit configuration (SPST), number of positions (12), current rating (150mA), voltage rating (30VDC), actuator type (rocker, raised level), mounting type (through hole), pitch (0.100"), height above board (0.315"), contact material and finish (copper alloy with gold plating), and operating temperature range (-40°C to +85°C).

Q: Can components with different position counts or current ratings substitute for the 76SB12?

A: No. The 12-position configuration and 150mA current rating are mandatory parameters. Components with different position counts or current ratings do not qualify as functional equivalents and may cause circuit malfunction or component failure.
