Grayhill 76RSB05 DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76RSB05 is a single-pole single-throw (SPST) rocker-actuated DIP switch rated for 150mA at 30VDC. This component is classified as obsolete, indicating that new production has been discontinued. The 76RSB05 features a 5-position through-hole configuration with gold-plated copper alloy contacts and a flush, recessed rocker actuator. Due to its obsolete status, identifying functionally equivalent active production alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 76RSB05 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration (SPST)
• Current rating (150mA minimum)
• Voltage rating (30VDC minimum)
• Contact material and finish (Copper Alloy with Gold plating)

Mechanical Compatibility:

• Number of positions (5)
• Actuator type (Rocker)
• Actuator level (Flush, Recessed)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Pitch spacing (0.100" / 2.54mm)
• Physical dimensions (Height, Length)

Environmental Compatibility:

• Operating temperature range (-40°C to 85°C)
• Mechanical and electrical life ratings (2,000 Cycles minimum)

The substitute part must match all parameters listed above to ensure direct functional and physical interchangeability without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 76RSB05T is the direct functional equivalent of the 76RSB05. All electrical, mechanical, and environmental parameters are identical. The primary distinction is product status and regulatory compliance:

76RSB05 (Obsolete): No longer in active production. Existing inventory is limited to 1,199 pieces. RoHS non-compliant status restricts use in new designs subject to RoHS3 regulations.

76RSB05T (Active): Currently in active production with 812 pieces in stock. ROHS3 compliant, meeting modern regulatory requirements for new product designs and procurement cycles. Tube packaging provides standard component handling and storage.

For new designs, ongoing production support, and regulatory compliance, the 76RSB05T is the appropriate selection. For legacy system maintenance where RoHS compliance is not required, the 76RSB05 remains functionally equivalent if inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB05T be used as a direct replacement for the 76RSB05 without PCB modification?

A: Yes. All electrical, mechanical, and dimensional parameters are identical. The 76RSB05T is a direct pin-for-pin and footprint-compatible substitute. No circuit redesign or PCB layout changes are required.

Q: What is the difference between the 76RSB05 and 76RSB05T?

A: The primary differences are product status and regulatory compliance. The 76RSB05 is obsolete and RoHS non-compliant. The 76RSB05T is in active production and ROHS3 compliant. Functionally and mechanically, both parts are identical.

Q: Why is the 76RSB05 classified as obsolete?

A: Grayhill Inc. has discontinued production of the 76RSB05. The 76RSB05T represents the active production equivalent within the same product series.

Q: Does packaging differ between these parts?

A: Yes. The 76RSB05 is packaged in standard format (packaging not specified). The 76RSB05T is supplied in Tube packaging, which is the standard distribution method for active production components.

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

A: No. Both parts have identical electrical ratings: 150mA at 30VDC, SPST configuration, 2,000 cycle mechanical and electrical life, and identical contact materials and finishes.

Q: Which part should be specified for new designs?

A: The 76RSB05T should be specified for all new designs. It is in active production, ROHS3 compliant, and ensures long-term supply chain availability and regulatory compliance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C.
