Toggle Switch DPDT 7203MD9AV2GE Equivalent & Substitute Parts

Part Overview

The 7203MD9AV2GE is an active production toggle switch manufactured by C&K, classified as a DPDT (Double Pole Double Throw) switch with On-Off-On functionality. This through-hole, right-angle vertical mounted component is rated for 5A at 120V AC and 28V DC, making it suitable for general-purpose switching applications requiring dual-pole control. Finding equivalent and substitute parts is necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific application requirements within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203MD9AV2GE is determined by the following critical parameters:

Circuit Configuration & Function: The substitute part must maintain DPDT circuit topology with On-Off-On switching function to preserve electrical behavior in dual-pole applications.

Mounting & Termination: Through-hole, right-angle vertical mounting with PC pin termination is required for mechanical and electrical compatibility with existing PCB layouts.

Actuator Type & Material: Standard round actuator with brass, chrome-plated construction ensures consistent user interface and durability characteristics.

Electrical Ratings: Substitute parts must support the application's voltage and current requirements. The 7203MD9AV2GE operates at 5A (AC/DC), 120V AC, and 28V DC. Substitute parts with lower ratings are not interchangeable for this application.

Environmental & Compliance: Operating temperature range of -30°C to 85°C and ROHS3 compliance are baseline requirements for equivalent parts.

The identified substitute part 100DP3T2B4M7RE from E-Switch shares the same circuit configuration, mounting type, and termination style. However, its electrical ratings (0.4VA at 20V AC/DC) are significantly lower than the main part, restricting its use to lower-power applications only.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (7203MD9AV2GE): Recommended for applications requiring 5A switching capacity at 120V AC or 28V DC. Active production status and ROHS3 compliance ensure long-term availability and regulatory alignment. Current inventory of 1,016 units supports immediate deployment.

Substitute Part (100DP3T2B4M7RE): This E-Switch component shares identical circuit topology, mounting configuration, and environmental operating range. However, its electrical ratings (0.4VA at 20V) represent a significant downgrade from the main part's 5A capacity. This substitute is suitable only for low-power signal switching applications that do not exceed 0.4VA or 20V. Direct substitution in applications designed for the 7203MD9AV2GE is not permissible due to insufficient electrical capacity. Both parts maintain active production status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T2B4M7RE replace the 7203MD9AV2GE in all applications?

A: No. While both parts share DPDT circuit configuration and identical mounting type, the 100DP3T2B4M7RE is rated for only 0.4VA at 20V, compared to the 7203MD9AV2GE's 5A at 120V AC. Substitution is valid only for applications with electrical requirements below 0.4VA and 20V maximum.

Q: What are the critical parameters that determine substitution compatibility?

A: Circuit configuration (DPDT), switch function (On-Off-On), mounting type (through-hole right-angle vertical), termination style (PC pin), and electrical ratings (current and voltage capacity) are the primary determinants. Operating temperature range and compliance certifications must also align.

Q: Are there differences in actuator dimensions between these parts?

A: Yes. The 7203MD9AV2GE has an actuator length of 6.86mm, while the 100DP3T2B4M7RE measures 5.08mm. This dimensional difference may affect panel cutout compatibility and user interface feel, though both use standard round brass, chrome-plated actuators.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant and rated for -30°C to 85°C operating temperature. The 7203MD9AV2GE is REACH Affected, while the 100DP3T2B4M7RE is REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the electrical life expectancy for these switches?

A: Both the 7203MD9AV2GE and 100DP3T2B4M7RE are rated for 40,000 electrical cycles, providing equivalent durability in their respective power classes.
