Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7211SD9AV2GE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SP3T
• Switch function: On-On-On
• Mounting type: Through Hole, Right Angle, Vertical
• Termination style: PC Pin
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 Cycles

Allowable Variation Parameters:

• Current rating: May be equal to or exceed 5A
• Voltage rating (AC): May be equal to or exceed 120V
• Voltage rating (DC): May be equal to or exceed 28V
• Actuator length: Minor variations acceptable within mechanical constraints
• Manufacturer: Different manufacturer acceptable if all parameters align

The substitute part 100DP6T1B4M7RE from E-Switch meets the mandatory matching criteria for circuit configuration, switch function, mounting type, termination style, and operating temperature range. However, this part operates at reduced current (0.4VA) and voltage ratings (20V AC/DC), making it suitable only for applications with lower electrical demands than the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (7211SD9AV2GE): Recommended for applications requiring the full specified electrical ratings of 5A at 120V AC or 28V DC. This part maintains active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Substitute Part (100DP6T1B4M7RE): Applicable only in applications where circuit load does not exceed 0.4VA at 20V maximum. This E-Switch component shares identical mechanical mounting, circuit topology, and temperature operating range, but operates at significantly reduced electrical capacity. Both parts maintain ROHS3 compliance and equivalent electrical life specifications.

Selection between these parts must be based on actual application voltage and current requirements. The substitute part cannot be used as a direct replacement in circuits designed for the full 5A/120V rating of the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 100DP6T1B4M7RE directly replace the 7211SD9AV2GE in all applications?

A: No. While both parts share identical SP3T circuit configuration, On-On-On switching function, and mechanical mounting characteristics, the substitute part is rated for only 0.4VA at 20V maximum. Direct substitution is only valid for applications operating below these electrical thresholds.

Q: What are the key compatibility factors between these two parts?

A: Both parts feature SP3T circuit configuration, On-On-On switching function, through-hole right-angle vertical mounting, PC pin termination, standard round actuator type, and -30°C to 85°C operating temperature range. These parameters ensure mechanical and functional interchangeability in the circuit topology.

Q: Does the 2.04mm difference in actuator length affect mechanical compatibility?

A: The 100DP6T1B4M7RE has a shorter actuator (10.41mm versus 12.45mm). This dimension difference may affect panel aesthetics and operator feel but does not impact electrical function or PCB mounting compatibility for through-hole applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 7211SD9AV2GE and 100DP6T1B4M7RE are ROHS3 compliant. The primary part is REACH Affected; the substitute part is REACH Unaffected. Verify REACH compliance requirements for your specific application jurisdiction.

Q: What is the electrical life expectancy for both parts?

A: Both parts are rated for 40,000 electrical cycles, providing equivalent operational durability under normal switching conditions within their respective voltage and current ratings.
