76RSB12 DIP Switch Rocker SPST 12 Position Equivalent & Substitute Parts

Part Overview

The 76RSB12 is a DIP switch rocker actuator manufactured by Grayhill Inc., designed for through-hole mounting applications requiring single-pole single-throw (SPST) switching functionality. This component operates at 150mA and 30VDC with a 12-position configuration and flush, recessed rocker actuator. The 76RSB12 carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support, maintenance, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76RSB12 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical categories:

Electrical Parameters: Circuit configuration (SPST), number of positions (12), current rating (150mA), and voltage rating (30VDC) must be identical.

Mechanical Parameters: Actuator type (rocker), actuator level (flush, recessed), mounting type (through hole), termination style (PC pin), pitch (0.100"), height above board (0.292"), and length (1.280") must match exactly.

Material Specifications: Contact material (copper alloy) and contact finish (gold) must be preserved.

Environmental Ratings: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) must be maintained.

The 76RSB12T qualifies as a direct substitute based on complete parameter alignment across all specified categories.

Parameter Comparison

Engineering Selection Recommendations

The 76RSB12T is the direct functional equivalent of the 76RSB12 and serves as the active replacement for this obsolete component. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing circuit designs and PCB layouts.

The 76RSB12T carries an active product status with ROHS3 compliance, providing long-term availability and regulatory alignment for new designs and production continuity. The main distinction between the two parts is packaging format (tube for 76RSB12T versus bulk for 76RSB12) and RoHS compliance status.

Selection of the 76RSB12T is appropriate for applications requiring the specified 12-position SPST rocker switch configuration with 150mA/30VDC ratings and through-hole mounting. The component maintains full electrical and mechanical compatibility with designs originally specified for the 76RSB12.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB12T be used as a direct replacement for the 76RSB12 in existing designs?

A: Yes. The 76RSB12T is electrically and mechanically identical to the 76RSB12 across all specified parameters, including circuit configuration, current and voltage ratings, actuator type, mounting dimensions, and contact materials. No design modifications are required.

Q: What is the difference between the 76RSB12 and 76RSB12T?

A: The primary differences are product status (76RSB12 is obsolete; 76RSB12T is active), RoHS compliance (76RSB12 is non-compliant; 76RSB12T is ROHS3 compliant), and packaging format (76RSB12 is supplied in bulk; 76RSB12T is supplied in tube packaging).

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both parts share identical mounting specifications: through-hole termination with 0.100" (2.54mm) pitch, 0.292" (7.41mm) height above board, and 1.280" (32.51mm) length. PCB layouts designed for the 76RSB12 require no modification for the 76RSB12T.

Q: Does the 76RSB12T meet current regulatory requirements?

A: Yes. The 76RSB12T is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components in most jurisdictions.

Q: What is the significance of the packaging difference?

A: The 76RSB12T is supplied in tube packaging, which is standard for active production components. This packaging format is suitable for automated assembly processes and provides protection during storage and handling. The bulk packaging of the 76RSB12 reflects its obsolete status.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications: 150mA current rating, 30VDC voltage rating, SPST circuit configuration, 2,000-cycle mechanical and electrical life, and -40°C to 85°C operating temperature range.
