SD02H0SBDR Equivalent & Substitute Parts

Part Overview

The SD02H0SBDR is a DIP slide switch manufactured by C&K, featuring SPST (Single Pole Single Throw) configuration with 2 positions. This surface mount component is rated for 100mA at 25VDC and is designed for applications requiring reliable switching in compact form factors. The part is currently active in production and widely available in inventory. Equivalent and substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements that align with alternative electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD02H0SBDR is determined by the following critical parameters: circuit configuration (SPST), number of positions (2), mounting type (surface mount), termination style (gull wing), and pitch (0.100" / 2.54mm). These parameters define the mechanical and electrical interface compatibility.

The substitute parts identified fall into two distinct groups based on current rating compatibility:

Group 1 (100mA Rating): Part 1825058-1 maintains the 100mA current rating of the main part, though with a reduced voltage rating of 24VDC compared to the 25VDC specification of SD02H0SBDR.

Group 2 (25mA Rating): Parts 1825059-1 and 1825059-5 operate at 25mA current rating, representing a significant reduction from the 100mA specification. These parts are electrically compatible only in applications where the actual current draw does not exceed 25mA.

All substitute parts maintain SPST configuration, 2-position design, surface mount technology, gull wing termination, and 0.100" pitch, ensuring mechanical compatibility with the original design footprint.

Parameter Comparison

Engineering Selection Recommendations

1825058-1 (TE Connectivity ALCOSWITCH): This part is suitable as a direct substitute where the application current requirement does not exceed 100mA and the circuit operates at or below 24VDC. The voltage rating differential (24VDC vs. 25VDC) is within typical design margins for most applications. Both parts are ROHS3 compliant and active in production. The operating temperature range is narrower (-30°C to 85°C vs. -40°C to 85°C), which may be a limiting factor in extreme cold environments.

1825059-1 and 1825059-5 (TE Connectivity ALCOSWITCH): These parts are suitable only in applications where the actual circuit current does not exceed 25mA. The 75mA reduction in current rating represents a significant design constraint. Both parts are ROHS3 compliant and active in production. Part 1825059-5 includes a Tape Seal feature and is packaged in Tube format. The operating temperature range limitation applies equally to both variants.

All substitute parts maintain full mechanical compatibility with the SD02H0SBDR footprint and are suitable for direct PCB placement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 1825058-1 be used as a direct replacement for SD02H0SBDR?

A: 1825058-1 is mechanically and functionally compatible with SD02H0SBDR for applications operating at 100mA or below and 24VDC or below. The primary design consideration is the voltage rating differential (24VDC vs. 25VDC). Both parts share identical circuit configuration, position count, mounting type, termination style, and pitch specifications.

Q: What is the key difference between 1825059-1 and 1825059-5?

A: Both parts are electrically and mechanically identical with 25mA current rating and 24VDC voltage rating. The primary difference is packaging: 1825059-1 is supplied in Tube format, while 1825059-5 is supplied in Tube format with Tape Seal feature. Both are suitable for identical applications.

Q: Can 1825059-1 or 1825059-5 replace SD02H0SBDR in high-current applications?

A: No. The 25mA current rating of 1825059-1 and 1825059-5 is insufficient for applications requiring 100mA switching capacity. These parts are suitable only in low-current signal switching applications where actual circuit current does not exceed 25mA.

Q: Are there temperature range considerations when substituting parts?

A: Yes. SD02H0SBDR operates from -40°C to 85°C, while all substitute parts (1825058-1, 1825059-1, 1825059-5) operate from -30°C to 85°C. Applications requiring operation below -30°C must use the original SD02H0SBDR specification.

Q: Do all parts meet the same compliance standards?

A: Yes. SD02H0SBDR, 1825058-1, 1825059-1, and 1825059-5 are all ROHS3 compliant and active in production status. All parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.
