Key Parameters

Substitute Part Grouping Explanation

The E-Switch 100DP6T1B4M7RE qualifies as a direct substitute for the C&K 7211SD9AV2BE22 based on the following critical parameters:

• Circuit Configuration: Both parts are SP3T switches with identical On-On-On switching function
• Electrical Ratings: Matching 0.4VA current rating and 20V AC/DC voltage specifications
• Mounting Configuration: Both feature through-hole, right-angle vertical mounting with PC pin termination
• Actuator Design: Both use standard round actuators with brass chrome-plated material
• Environmental Performance: Identical operating temperature range (-30°C to 85°C) and 40,000-cycle electrical life
• Compliance: Both are ROHS3 compliant with EAR99 ECCN classification

The primary difference is actuator length (12.45mm for 7211SD9AV2BE22 versus 10.41mm for 100DP6T1B4M7RE), which does not affect electrical substitution but may require mechanical panel layout verification.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7211SD9AV2BE22 and E-Switch 100DP6T1B4M7RE are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Inventory Availability: C&K 7211SD9AV2BE22 has 725 units in stock; E-Switch 100DP6T1B4M7RE has 1,224 units available
• Mechanical Fit: The 2.04mm actuator length difference requires panel cutout verification to ensure proper engagement and clearance
• Supply Chain Requirements: Both parts carry EAR99 classification and identical HTSUS codes, presenting no regulatory differentiation
• Compliance Status: C&K part is REACH Affected; E-Switch part is REACH Unaffected, which may influence selection for specific end-use applications

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP6T1B4M7RE directly replace the C&K 7211SD9AV2BE22 in existing designs?

A: Electrical substitution is direct due to identical circuit configuration, voltage/current ratings, and termination style. Mechanical verification is required due to the 2.04mm actuator length difference, which may affect panel mounting depth and actuator protrusion.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with EAR99 ECCN classification. The C&K part is REACH Affected while the E-Switch part is REACH Unaffected. Applications subject to REACH regulations should consider this distinction.

Q: What does the "Jumper needed to achieve triple throw" feature mean?

A: Both parts require a jumper configuration to achieve full SP3T functionality. This is a standard design feature for these switch models and applies equally to both the main part and substitute.

Q: Are the PC pin terminations compatible with standard PCB footprints?

A: Both parts use identical PC pin termination style. PCB footprint compatibility depends on the specific pin spacing and layout of your design. Consult the detailed mechanical drawings for each manufacturer to confirm footprint alignment.

Q: What is the significance of MSL Rating 1 (Unlimited)?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life under standard storage conditions and require no special moisture control during handling or storage.
