SD05H0BD DIP Switch SPST 5 Position Equivalent & Substitute Parts

Part Overview

The SD05H0BD is an active C&K DIP switch featuring SPST (Single Pole Single Throw) circuit configuration with 5 positions, rated for 100mA at 25VDC. This through-hole mounted component uses a slide actuator with standard flush/recessed actuation level and gold-plated beryllium copper contacts. The part is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications requiring reliable switching functionality across extended temperature ranges (-40°C to 85°C). Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and compliance certifications align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD05H0BD are identified based on the following critical parameters that determine functional and mechanical compatibility:

Core Electrical Parameters: Circuit type (SPST), number of positions (5), voltage rating (minimum 25VDC), and current rating (minimum 100mA). Substitute parts must meet or exceed these electrical specifications.

Mechanical Compatibility: Through-hole mounting type, 0.100" (2.54mm) pitch spacing, and flush/recessed actuator level ensure PCB footprint compatibility and assembly process alignment.

Environmental & Compliance Requirements: Operating temperature range (-40°C to 85°C), RoHS3 compliance, and MSL 1 rating ensure regulatory acceptance and reliability in target applications.

Actuator Type Consideration: While the primary part uses a slide actuator, rocker actuators with identical electrical ratings and mechanical dimensions are functionally equivalent for switching applications, with the distinction being user interface preference and actuation force profile.

The identified substitute part 76RSB05T from Grayhill Inc. meets these criteria with higher current (150mA) and voltage (30VDC) ratings, providing design margin while maintaining mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (SD05H0BD): Select when slide actuator operation is specified or preferred. Active product status with full ROHS3 compliance and unlimited MSL rating supports immediate deployment in regulated applications.

Substitute Part (76RSB05T): Select when rocker actuator interface is acceptable or preferred. Higher current (150mA) and voltage (30VDC) ratings provide design margin above the 100mA/25VDC requirement. ROHS3 compliance and MSL 1 rating match regulatory requirements. Active product status ensures supply continuity.

Selection Basis: Both parts satisfy SPST 5-position switching requirements with identical pitch, mounting type, temperature range, and lifecycle ratings. Substitution is valid based on electrical parameter compatibility (rated values meet or exceed application requirements), mechanical footprint alignment (through-hole, 0.100" pitch), and compliance certification equivalence (ROHS3, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the 76RSB05T rocker actuator replace the SD05H0BD slide actuator in the same PCB assembly?

A: Yes. Both parts share identical through-hole mounting pitch (0.100"), flush/recessed actuator level, and PC pin termination. The primary difference is actuator type (rocker vs. slide), which does not affect electrical compatibility or PCB footprint. Verify that the application design does not specify actuator type as a functional requirement.

Q: Are the electrical ratings of the 76RSB05T sufficient for SD05H0BD applications?

A: Yes. The 76RSB05T is rated for 150mA at 30VDC, which exceeds the SD05H0BD specification of 100mA at 25VDC. This provides design margin and is suitable for applications designed for the lower-rated part.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, and operate across -40°C to 85°C. Both maintain 2,000 mechanical and electrical life cycles. Compliance and environmental performance are equivalent.

Q: What is the difference in height above board between these parts?

A: The SD05H0BD has a height of 0.168" (4.27mm), while the 76RSB05T measures 0.292" (7.41mm). Verify clearance in the target application before substitution, particularly in space-constrained designs.

Q: Can these parts be used interchangeably in production?

A: Substitution is valid when electrical requirements (SPST, 5 positions, minimum 100mA/25VDC) are met and mechanical clearance is confirmed. Actuator type preference and height constraints must be evaluated for each application. Both parts are active products with established supply chains.
