Grayhill 78RB06S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 78RB06S is a single-pole single-throw (SPST) DIP switch with 6 positions, rated for 150mA at 30VDC. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The 78RB06S features a slide actuator with standard (flush, recessed) positioning, gold-plated copper alloy contacts, and through-hole PC pin termination suitable for washable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 78RB06S is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPST
• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC
• Number of positions must equal 6

Mechanical Compatibility Requirements:

• Actuator type must be Slide (Standard)
• Actuator level must be Flush, Recessed
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Pitch must be 0.100" (2.54mm), Full
• Height above board must be 0.265" (6.73mm)

Material & Environmental Requirements:

• Contact material must be Copper Alloy
• Contact finish must be Gold
• Operating temperature range must encompass -40°C to 85°C
• Washable capability must be present
• Tape Seal feature must be present

The 78RB06ST meets all substitution criteria and is identified as the direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 78RB06ST is the direct functional equivalent of the 78RB06S. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance.

Status Consideration: The 78RB06S is classified as obsolete, while the 78RB06ST maintains active product status. For new designs or ongoing procurement, the 78RB06ST is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Consideration: The 78RB06ST achieves ROHS3 compliance, whereas the 78RB06S is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 78RB06ST satisfies these regulatory requirements.

Packaging Consideration: The 78RB06ST is supplied in Tube packaging, which may differ from the original packaging specification of the 78RB06S. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 78RB06ST be used as a direct replacement for the 78RB06S in existing designs?

A: Yes. The 78RB06ST is electrically and mechanically identical to the 78RB06S across all functional parameters. Both components feature identical SPST circuit configuration, 6-position count, 150mA current rating, 30VDC voltage rating, slide actuator type, through-hole mounting, and PC pin termination. Footprint and pinout compatibility are confirmed.

Q: What is the difference between the 78RB06S and 78RB06ST?

A: The primary differences are product status and regulatory compliance. The 78RB06S is obsolete and RoHS non-compliant. The 78RB06ST is an active product that achieves ROHS3 compliance. Electrical and mechanical specifications are identical. The 78RB06ST is supplied in Tube packaging.

Q: Why is the 78RB06S classified as obsolete?

A: The 78RB06S has been superseded by the 78RB06ST. Grayhill Inc. has transitioned this product line to the active 78RB06ST variant, which offers improved regulatory compliance and ongoing manufacturing support.

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

A: No. Both components deliver identical performance across electrical and mechanical parameters, including current rating, voltage rating, actuator response, contact material, contact finish, operating temperature range, mechanical life, and electrical life.

Q: What packaging options are available for the substitute part?

A: The 78RB06ST is supplied in Tube packaging. Confirm packaging compatibility with your assembly and procurement requirements.

Q: Is the 78RB06ST suitable for washable applications?

A: Yes. The 78RB06ST retains the washable capability of the original 78RB06S and includes Tape Seal features for washable circuit board applications.

Q: What is the pitch specification for these DIP switches?

A: Both the 78RB06S and 78RB06ST feature a pitch of 0.100" (2.54mm), Full. This standard pitch ensures compatibility with conventional DIP switch footprints and through-hole PCB layouts.
