Grayhill 78RB07 DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 78RB07 is a slide-actuated DIP switch featuring SPST (Single Pole Single Throw) configuration with 7 positions, rated for 150mA at 30VDC. This component is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations. The 78RB07T serves as the direct successor, offering identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78RB07 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPST), position count (7), current rating (150mA), and voltage rating (30VDC) must be identical.

Mechanical Parameters: Actuator type (Slide Standard), mounting method (Through Hole), pitch spacing (0.100"), and height above board (0.265") must match exactly.

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

The 78RB07T qualifies as a direct substitute because it maintains 100% equivalence across all electrical, mechanical, and environmental specifications while offering improved product status and regulatory compliance.

Engineering Selection Recommendations

For New Designs: The 78RB07T is the appropriate selection. It maintains complete functional and mechanical equivalence to the 78RB07 while offering active product status and ROHS3 compliance, eliminating regulatory and supply chain risks associated with obsolete components.

For Legacy System Maintenance: The 78RB07 remains functionally suitable for existing applications where the component is already integrated. However, transition to 78RB07T is recommended for long-term sustainability, as the 78RB07 is obsolete and subject to inventory depletion.

Compliance Considerations: The 78RB07T meets ROHS3 requirements, whereas the 78RB07 does not. Both parts maintain REACH Unaffected status and EAR99 export classification. Selection should account for end-product regulatory requirements.

Packaging Impact: The 78RB07T is supplied in tube packaging, while the 78RB07 is supplied in bulk. This difference affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 78RB07T be used as a direct replacement for the 78RB07 in existing PCB assemblies?

A: Yes. The 78RB07T is a direct substitute with identical electrical ratings (150mA, 30VDC, SPST, 7 positions), mechanical dimensions (0.265" height, 0.100" pitch), and mounting configuration (Through Hole, PC Pin termination). No circuit modifications are required.

Q: What is the primary reason to transition from 78RB07 to 78RB07T?

A: The 78RB07 is classified as obsolete, creating supply and long-term availability risks. The 78RB07T is an active product with identical specifications and improved compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Q: Are there differences in actuator feel or mechanical operation between these parts?

A: No. Both parts feature identical slide actuator design with flush, recessed actuation level and equivalent mechanical life ratings (2,000 cycles).

Q: Does packaging format affect component performance?

A: No. The difference between bulk packaging (78RB07) and tube packaging (78RB07T) affects logistics and storage only. Electrical and mechanical performance is identical.

Q: What are the critical parameters that must match for substitution eligibility?

A: Circuit type (SPST), position count (7), current rating (150mA), voltage rating (30VDC), actuator type (Slide Standard), mounting method (Through Hole), pitch (0.100"), and height above board (0.265") must all be identical.

Q: Is the 78RB07T suitable for applications requiring RoHS compliance?

A: Yes. The 78RB07T is ROHS3 Compliant, making it suitable for applications with RoHS requirements. The 78RB07 is RoHS non-compliant and should not be used in RoHS-regulated applications.

Q: What is the operating temperature range for both parts?

A: Both the 78RB07 and 78RB07T operate across -40°C to 85°C, with identical mechanical and electrical life specifications of 2,000 cycles.
