Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201K9CME3 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and length (Locking Lever, 17.88mm)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)

The C&K 7201K9CSE3 meets all these criteria and is classified as a direct substitute. Differences in product status, RoHS compliance, and terminal sealing do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201K9CSE3 is the direct substitute for the obsolete 7201K9CME3. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 7201K9CSE3 offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the 7201K9CSE3 achieves RoHS compliance and REACH affected status, meeting modern regulatory requirements for new designs and procurement cycles. The epoxy sealed terminals on the 7201K9CSE3 provide enhanced environmental protection compared to the red anodized finish of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 7201K9CSE3 be used as a direct replacement for the 7201K9CME3 in existing designs?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC/28V DC), circuit configuration (DPDT), switch function (On-On), mounting type (Through Hole), actuator specifications (Locking Lever, 17.88mm), and termination style (PC Pin). Physical and electrical compatibility is complete.

Q: What is the difference between the red anodized finish and epoxy sealed terminals?

A: The 7201K9CME3 features a red anodized finish on the actuator. The 7201K9CSE3 uses epoxy sealed terminals for enhanced environmental protection. This difference does not affect electrical performance or mechanical fit.

Q: Why is the 7201K9CME3 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 7201K9CSE3 provides equivalent functionality with active manufacturing support.

Q: Does RoHS compliance affect compatibility?

A: No. RoHS compliance is a manufacturing and material standard that does not alter electrical or mechanical performance. The 7201K9CSE3 maintains full compatibility while meeting RoHS requirements.

Q: Are there any differences in operating temperature or electrical life?

A: No. Both parts operate across -30°C to 85°C and are rated for 100,000 electrical cycles.
