EG2205 Equivalent & Substitute Parts

Part Overview

The EG2205 is a slide switch with DPDT (Double Pole Double Throw) configuration manufactured by E-Switch. This component is rated for 300mA DC at 30V and features a through-hole mounting design with silver-plated copper alloy contacts. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EG2205 is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain electrical functionality
• Current Rating: Minimum 300mA to support existing load requirements
• Voltage Rating: Must accommodate the 30V DC operating condition
• Contact Timing: Non-Shorting (BBM) operation is preferred to prevent transient switching artifacts
• Mounting Type: Through-hole configuration required for PCB compatibility
• Termination Style: PC pin termination for direct board insertion
• Contact Material & Finish: Copper alloy with silver plating for reliable electrical performance

The substitute part 1825261-1 maintains DPDT configuration, 300mA current capacity, and through-hole PC pin termination. However, differences exist in voltage rating, contact timing, and mechanical specifications that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 1825261-1 from TE Connectivity ALCOSWITCH Switches is an active product suitable for replacing the obsolete EG2205 in applications where the following conditions are met:

Compatibility Factors:

• Both components maintain DPDT circuit configuration and 300mA current capacity
• Both feature through-hole PC pin termination for direct PCB mounting
• Both utilize copper alloy contacts with silver plating
• Both are ROHS3 compliant

Application Considerations:

• The 1825261-1 operates at 125V AC, which exceeds the EG2205's 30V DC rating and provides margin for DC applications at lower voltages
• The substitute features Shorting (MBB) contact timing versus the original's Non-Shorting (BBM) configuration; this difference affects switching transient behavior
• Actuator length differs (2.30mm vs 4.00mm) and operating force is higher (600gf vs 250gf), requiring mechanical fit verification
• The substitute provides documented mechanical and electrical life ratings (15,000 cycles), whereas the original specifications do not include these values
• Extended operating temperature range (-20°C to 85°C) on the substitute provides additional thermal margin

Compliance Status: Both components are ROHS3 compliant and carry EAR99 ECCN classification. The substitute's active product status ensures ongoing availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can the 1825261-1 directly replace the EG2205 without circuit modifications?

A: The 1825261-1 maintains the same DPDT configuration, current rating, and through-hole PC pin termination. However, differences in contact timing (Shorting vs Non-Shorting), actuator dimensions, and operating force require mechanical fit verification and evaluation of switching transient effects on the target circuit.

Q: What is the significance of the contact timing difference (BBM vs MBB)?

A: BBM (Break-Before-Make, Non-Shorting) ensures no momentary contact between switch positions. MBB (Make-Before-Break, Shorting) creates a brief overlap during switching. The choice depends on circuit requirements; some applications tolerate or benefit from the brief connection, while others require isolation between positions.

Q: Is the 125V AC rating of the 1825261-1 suitable for 30V DC applications?

A: The substitute's 125V AC rating provides adequate voltage margin for DC operation at 30V. AC voltage ratings are typically higher than equivalent DC ratings due to different electrical stress characteristics. The 300mA current capacity is maintained across both specifications.

Q: How do the actuator length and operating force differences affect board design?

A: The EG2205 features a 4.00mm actuator with 250gf operating force, while the 1825261-1 has a 2.30mm actuator with 600gf operating force. These differences impact mechanical clearance requirements and user actuation feel. PCB layout and enclosure design must accommodate the shorter actuator, and the higher operating force may require user interface adjustment.

Q: Are both components suitable for high-reliability applications?

A: Both components are ROHS3 compliant. The 1825261-1 provides documented mechanical and electrical life ratings (15,000 cycles), supporting reliability predictions. The EG2205's life specifications are not provided in the available data. For high-reliability requirements, the substitute's documented performance characteristics offer better traceability.

Q: What packaging considerations apply to these components?

A: The EG2205 is available in bulk packaging with 1082 pieces in stock. The 1825261-1 is also bulk packaged with 1965 pieces available. Both are through-hole components suitable for standard PCB assembly processes.
