Grayhill 76PRB09T DIP Switch SPST Piano Actuator Equivalent & Substitute Parts

Part Overview

The Grayhill 76PRB09T is a 9-position DIP switch with SPST (Single Pole Single Throw) circuit configuration, piano actuator, and rated for 150mA at 30VDC. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement planning. The 76PRB09T remains available in inventory but is no longer in active production. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges to ensure direct replacement capability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 76PRB09T is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Circuit type must remain SPST
• Current rating must be equal to or greater than 150mA
• Voltage rating must be equal to or greater than 30VDC
• Contact material and finish must be equivalent (Copper Alloy with Gold finish)

Mechanical Compatibility Requirements:

• Actuator type must be Piano with Raised level
• Mounting configuration must be Through Hole, Right Angle
• Pitch must be 0.100 inches (2.54mm)
• Height above board must be 0.301 inches (7.65mm)
• Termination style must be PC Pin

Environmental and Compliance Requirements:

• Operating temperature range must encompass -40°C to 85°C
• RoHS compliance status must be maintained
• MSL rating must be 1 or equivalent

The 76PRB09T specifies 9 positions. Substitute parts with different position counts (such as 10-position variants) are considered compatible only when all other electrical and mechanical parameters align and the application design permits position count variation.

Engineering Selection Recommendations

76PRB10T as Primary Substitute:

The Grayhill 76PRB10T is the designated substitute for the obsolete 76PRB09T. This substitution is based on the following engineering criteria:

1. Electrical Equivalence: Both parts maintain identical current (150mA) and voltage (30VDC) ratings with matching SPST circuit configuration and contact specifications (Copper Alloy, Gold finish).

2. Mechanical Equivalence: Pitch (0.100"), height above board (0.301"), actuator type (Piano, Raised), and mounting configuration (Through Hole, Right Angle) are identical across both parts.

3. Environmental Compliance: Both parts operate across the identical temperature range (-40°C to 85°C) and maintain MSL rating of 1 (Unlimited).

4. Regulatory Compliance: The 76PRB10T carries ROHS3 compliance, which supersedes the RoHS compliance of the 76PRB09T, ensuring continued regulatory alignment.

5. Product Status Advantage: The 76PRB10T is in active production status with confirmed inventory availability (1,090 pieces), providing supply chain continuity for the obsolete 76PRB09T.

6. Position Count Consideration: The 76PRB10T provides 10 positions compared to the 76PRB09T's 9 positions. This variation does not affect electrical or mechanical compatibility. Applications utilizing fewer than 10 positions can operate the 76PRB10T with unused positions remaining in the off state.

Frequently Asked Questions (FAQ)

Q: Can the 76PRB10T directly replace the 76PRB09T in existing PCB assemblies?

A: Yes. The 76PRB10T maintains identical electrical ratings (150mA, 30VDC, SPST), mechanical dimensions (pitch 0.100", height 0.301"), actuator configuration (Piano, Raised), and mounting type (Through Hole, Right Angle). The 10-position configuration is mechanically and electrically compatible with applications designed for the 9-position 76PRB09T.

Q: What is the significance of the position count difference between 76PRB09T and 76PRB10T?

A: The 76PRB09T contains 9 independent switch positions while the 76PRB10T contains 10 positions. Both parts use identical 0.100-inch pitch spacing. Applications requiring only 9 positions can utilize the 76PRB10T with the 10th position unused. The additional position does not affect electrical performance or mechanical fit.

Q: Are there packaging differences between these parts?

A: The 76PRB09T is packaged in standard format, while the 76PRB10T is supplied in Tube packaging. Both packaging formats are suitable for automated assembly processes and do not affect component functionality or compatibility.

Q: How do the RoHS compliance statuses compare?

A: The 76PRB09T carries RoHS Compliant status, while the 76PRB10T carries ROHS3 Compliant status. ROHS3 represents an updated compliance standard that maintains all RoHS requirements. This upgrade ensures the 76PRB10T meets current and future regulatory requirements.

Q: What is the inventory status for each part?

A: The 76PRB09T (obsolete) has 943 pieces available in stock. The 76PRB10T (active production) has 1,090 pieces available in stock. The active production status of the 76PRB10T ensures long-term availability for future procurement needs.

Q: Are the mechanical life and electrical life ratings identical?

A: Yes. Both the 76PRB09T and 76PRB10T are rated for 2,000 mechanical cycles and 2,000 electrical cycles, indicating equivalent durability and operational lifespan under specified conditions.

Q: Can the 76PRB10T be used in applications with strict position count requirements?

A: Applications with strict 9-position requirements must evaluate whether the additional 10th position creates design conflicts. In most applications, the unused 10th position presents no functional impact. Design review is necessary only if the application has explicit position count constraints.
