SD10H0B DIP Switch SPST 10 Position Equivalent & Substitute Parts

Part Overview

The SD10H0B is a DIP switch manufactured by C&K, featuring SPST (Single Pole Single Throw) circuit configuration with 10 positions. This through-hole component is rated for 100mA at 25VDC with a slide actuator and gold-plated beryllium copper contacts. The product is active and widely used in applications requiring configurable switching logic on printed circuit boards.

Substitute parts may be required due to inventory constraints, end-of-life considerations, or application-specific performance requirements. Alternative models must maintain compatibility across critical electrical and mechanical parameters including circuit type, position count, current and voltage ratings, mounting configuration, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD10H0B is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

• Circuit configuration: SPST
• Number of positions: 10
• Mounting type: Through Hole
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin

Electrical Parameters (Must Meet or Exceed):

• Current rating: Minimum 100mA
• Voltage rating: Minimum 25VDC

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The substitute parts listed below satisfy these criteria with variations in actuator type and contact material that do not compromise functional compatibility in standard DIP switch applications.

Parameter Comparison

Engineering Selection Recommendations

209-10LPST (CTS Electrocomponents): This substitute maintains identical mechanical dimensions and actuator type to the SD10H0B with matching current rating. The voltage rating is 20VDC, which is below the primary part specification. This part is suitable for applications operating at or below 20VDC. All parts are active products with ROHS3 compliance and unlimited MSL rating.

78RB10ST (Grayhill Inc.): This substitute provides higher current (150mA) and voltage (30VDC) ratings, making it suitable for applications requiring greater electrical headroom. The slide actuator type matches the SD10H0B. Physical height increases to 0.265" (6.73mm) compared to 0.178" (4.52mm) on the primary part. This dimensional difference must be evaluated for PCB layout compatibility. Contact material differs (copper alloy versus beryllium copper) but maintains gold finish and equivalent performance characteristics.

76RSB10ST (Grayhill Inc.): This substitute features a rocker actuator instead of slide actuator, with higher current (150mA) and voltage (30VDC) ratings. Physical height is 0.292" (7.41mm), the highest among all options. The rocker actuator provides different user interface characteristics and may require design consideration for panel space and actuation force. Contact material is copper alloy with gold finish.

All substitute parts maintain ROHS3 compliance, active product status, and MSL rating of 1 (Unlimited), ensuring regulatory and environmental compatibility with the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 209-10LPST replace the SD10H0B in all applications?

A: The 209-10LPST is functionally compatible for applications operating at 20VDC or below. If your application requires 25VDC operation, this substitute is not appropriate. Verify your circuit voltage specification before selection.

Q: What is the primary difference between the 78RB10ST and 76RSB10ST?

A: Both parts are manufactured by Grayhill with identical electrical ratings (150mA, 30VDC). The primary difference is actuator type: 78RB10ST uses a slide actuator (matching the SD10H0B style), while 76RSB10ST uses a rocker actuator. The rocker design results in greater height above board (0.292" versus 0.265"). Select based on your panel interface requirements and available PCB clearance.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: Yes. The 78RB10ST and 76RSB10ST have increased height above board compared to the SD10H0B (0.265" and 0.292" respectively versus 0.178"). Verify your PCB layout and enclosure design accommodate the taller component. Pitch and termination style remain consistent across all parts at 0.100" (2.54mm) and PC Pin configuration.

Q: Do all substitute parts meet the same environmental specifications?

A: Yes. All substitute parts operate across the -40°C ~ 85°C temperature range and maintain ROHS3 compliance with MSL rating of 1 (Unlimited), matching the SD10H0B environmental and regulatory profile.

Q: Which substitute offers the best electrical margin for demanding applications?

A: The 78RB10ST and 76RSB10ST both provide 150mA current rating and 30VDC voltage rating, exceeding the SD10H0B specifications (100mA, 25VDC). Select between these two based on actuator type preference and physical height constraints.

Q: Is contact material substitution (beryllium copper to copper alloy) a concern?

A: Both materials are gold-plated and suitable for standard DIP switch applications. Copper alloy contacts in the Grayhill parts maintain equivalent performance and reliability for typical switching applications. Material selection should not be a limiting factor for standard industrial and commercial applications.
