Grayhill 76SB05S DIP Switch Rocker Actuator Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB05S is a 5-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. The 76SB05S features a raised rocker actuator with gold-plated copper alloy contacts, thermoplastic housing, and operates across the industrial temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB05S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 5
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Contact finish: Gold

Electrical Performance Criteria:

• Current rating: minimum 150mA
• Voltage rating: minimum 30VDC
• Operating temperature range: must encompass -40°C to 85°C

Mechanical Criteria:

• Actuator level: Raised
• Height above board: 0.315" (8.00mm)
• Washable: Yes

Two substitute parts have been identified based on these parameters. The 76SB05ST from Grayhill Inc. provides direct functional equivalence with identical electrical and mechanical specifications. The 206-5ST from CTS Electrocomponents represents a partial substitute with deviations in actuator type, current rating, and voltage rating that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

76SB05ST (Grayhill Inc.) - Primary Substitute

The 76SB05ST is the direct functional equivalent of the 76SB05S. All electrical parameters (150mA, 30VDC), mechanical dimensions (0.315" height, 0.100" pitch), and actuator characteristics (rocker, raised level) are identical. The 76SB05ST is currently in active production status with 5,799 units in stock. The primary distinction is RoHS3 compliance, which addresses regulatory requirements for new designs. The 76SB05ST is packaged in tube format and maintains identical mechanical life (2,000 cycles) and electrical life (2,000 cycles) specifications. This part is suitable for direct replacement in applications where the 76SB05S was previously specified.

206-5ST (CTS Electrocomponents) - Conditional Substitute

The 206-5ST shares the same circuit configuration (SPST), position count (5), mounting type (through hole), and pitch (0.100") as the 76SB05S. However, this part exhibits three significant parameter deviations:

1. Current Rating Reduction: 50mA versus 150mA. The 206-5ST cannot support applications requiring the full 150mA current capacity of the original part.

2. Voltage Rating Reduction: 24VDC versus 30VDC. The 206-5ST is rated for lower voltage operation and is not suitable for 30VDC applications.

3. Actuator Type Difference: Slide (standard) actuator versus rocker actuator. This represents a different user interface and may affect PCB layout and user interaction requirements.

The 206-5ST is suitable only for applications where current requirements do not exceed 50mA and voltage requirements do not exceed 24VDC. The slide actuator may be acceptable depending on design constraints. The 206-5ST offers extended electrical life (10,000 cycles) and broader operating temperature range (-55°C to 85°C). This part is in active production with 713 units in stock and is RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the 76SB05ST directly replace the 76SB05S without PCB modification?

A: Yes. The 76SB05ST maintains identical mechanical dimensions, pitch spacing (0.100"), height above board (0.315"), and through-hole PC pin termination. No PCB layout changes are required for direct substitution.

Q: What is the primary reason to transition from 76SB05S to 76SB05ST?

A: The 76SB05S is classified as obsolete, while the 76SB05ST is in active production. The 76SB05ST also achieves RoHS3 compliance, addressing regulatory requirements for new product designs and manufacturing in restricted substance-regulated markets.

Q: Is the 206-5ST a suitable replacement for the 76SB05S in all applications?

A: No. The 206-5ST has reduced current rating (50mA versus 150mA) and voltage rating (24VDC versus 30VDC). It is suitable only for applications operating at or below these reduced specifications. Additionally, the slide actuator differs from the rocker actuator of the original part.

Q: What are the key electrical differences between the 76SB05ST and 206-5ST?

A: The 76SB05ST maintains the original 150mA current rating and 30VDC voltage rating. The 206-5ST is limited to 50mA and 24VDC. Both parts are SPST 5-position switches with gold-plated contacts and identical pitch spacing.

Q: Are both substitute parts available in the same packaging format?

A: Both the 76SB05ST and 206-5ST are supplied in tube packaging. The original 76SB05S was supplied with tape seal packaging. Tube packaging is standard for active production parts and does not affect electrical or mechanical performance.

Q: What is the mechanical life expectancy of the substitute parts?

A: The 76SB05ST maintains the same mechanical life specification as the original part: 2,000 cycles. The 206-5ST does not specify mechanical life in the provided data. The 206-5ST specifies 10,000 electrical life cycles, compared to 2,000 cycles for both the 76SB05S and 76SB05ST.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Both the 76SB05ST and 206-5ST are RoHS3 compliant. Both are REACH unaffected and classified under ECCN EAR99. The original 76SB05S is RoHS non-compliant, which is a primary driver for transitioning to compliant alternatives in new designs.

Q: Can the 206-5ST be used in applications requiring the full 150mA rating of the 76SB05S?

A: No. The 206-5ST is rated for maximum 50mA. Using this part in applications requiring 150mA would exceed component ratings and create reliability and safety risks.
