SD05H1B DIP Switch SPST 5 Position Equivalent & Substitute Parts

Part Overview

The SD05H1B is a DIP switch manufactured by C&K, featuring a single-pole single-throw (SPST) circuit configuration with 5 positions. This through-hole mounted component operates at 100mA and 25VDC with a slide actuator design. The part is Active in product status and widely used in electronic assemblies requiring manual configuration switching. Equivalent and substitute parts are identified when design requirements allow for higher electrical ratings, different actuator types, or alternative form factors while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD05H1B are qualified based on the following criteria:

Core Compatibility Requirements:

• SPST circuit configuration maintained
• 5-position count maintained
• Through-hole mounting with 0.100" (2.54mm) pitch maintained
• Gold-plated contacts maintained
• Operating temperature range of -40°C ~ 85°C maintained
• Active product status maintained
• ROHS3 compliance maintained

Allowable Variations:

• Current rating may be equal to or greater than 100mA
• Voltage rating may be equal to or greater than 25VDC
• Actuator type may differ (slide vs. rocker) provided mechanical interface is compatible
• Contact material may vary (Beryllium Copper to Copper Alloy)
• Body material may vary (Polyphthalamide to Thermoplastic)
• Height above board and overall length may vary within assembly space constraints

The substitute parts listed below meet these criteria and are suitable for direct replacement in applications where the higher electrical ratings and alternative actuator designs do not conflict with board layout or user interface requirements.

Parameter Comparison

Engineering Selection Recommendations

76SB05ST (Grayhill Inc.): This substitute provides higher current (150mA) and voltage (30VDC) ratings compared to the SD05H1B. The rocker actuator differs mechanically from the slide actuator of the main part. Selection of this part requires verification that the rocker actuator interface is compatible with the application's mechanical constraints and user interaction requirements. All compliance certifications (ROHS3, REACH Unaffected) are equivalent.

78B05ST (Grayhill Inc.): This substitute maintains the slide actuator type of the SD05H1B while providing higher current (150mA) and voltage (30VDC) ratings. The mechanical form factor is more similar to the main part, with differences limited to height above board (0.315" vs. 0.178") and overall length (0.580" vs. 0.558"). This part is suitable for applications where the increased electrical headroom is beneficial and board space accommodates the slightly larger footprint. All compliance certifications are equivalent.

Both substitutes are Active products with identical operating temperature ranges and lifecycle ratings. Selection between them depends on actuator type preference and available board space.

Frequently Asked Questions (FAQ)

Q: Can the 76SB05ST rocker actuator be used as a direct replacement for the SD05H1B slide actuator?

A: The 76SB05ST maintains the same 5-position SPST configuration, pitch, and electrical ratings. However, the rocker actuator has a different mechanical interface and user interaction profile compared to the slide actuator. Direct replacement is possible only if the application's mechanical design and user interface requirements accommodate the rocker actuator type.

Q: What is the primary advantage of using 78B05ST over the SD05H1B?

A: The 78B05ST provides higher current (150mA vs. 100mA) and voltage (30VDC vs. 25VDC) ratings while maintaining the same slide actuator type. This allows for operation in applications with higher electrical demands. The trade-off is a slightly larger physical footprint (0.315" height vs. 0.178", 0.580" length vs. 0.558").

Q: Are all three parts compatible with the same PCB footprint?

A: All three parts share the same 0.100" (2.54mm) pitch and through-hole termination style. However, the SD05H1B and 78B05ST have different heights above board (0.178" vs. 0.315"), and the 76SB05ST also has a height of 0.315". PCB layout compatibility depends on whether the design accommodates these height variations and the different actuator profiles.

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

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, operate across -40°C ~ 85°C, have MSL rating of 1 (Unlimited), and share identical mechanical and electrical lifecycle ratings of 2,000 cycles.

Q: Which substitute should be selected for a space-constrained application?

A: The SD05H1B has the smallest height above board at 0.178". If board space is critical, the original part is the optimal choice. If space permits and higher electrical ratings are required, the 78B05ST (with its slide actuator) is preferable to the 76SB05ST due to similar form factor.
