Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201P3YV71ME2 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Flat Anti-Rotation, 11.43mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (100,000 Cycles)

The C&K 7201P3YV71SE2 meets all these criteria and qualifies 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 7201P3YV71SE2 is the direct substitute for the obsolete 7201P3YV71ME2. Selection of the substitute part is supported by:

• Identical electrical specifications across all rated parameters
• Identical mechanical and mounting specifications
• Active product status ensuring continued availability and supply chain reliability
• RoHS compliance of the substitute part, meeting modern regulatory requirements
• Enhanced terminal sealing (epoxy sealed) providing improved environmental protection compared to the original part

For applications requiring RoHS non-compliant components or specific actuator color specifications, the original part number should be retained if inventory permits. Otherwise, the 7201P3YV71SE2 provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7201P3YV71SE2 be used as a direct replacement in existing designs using the 7201P3YV71ME2?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), and mechanical specifications including panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator geometry (11.43mm flat anti-rotation). Panel mounting and PC pin termination are identical.

Q: What is the difference between the black actuator of the original part and the substitute?

A: The 7201P3YV71ME2 features a black actuator, while the 7201P3YV71SE2 does not specify actuator color. Both actuators are brass with chrome plating and maintain identical mechanical function and anti-rotation properties.

Q: Does the epoxy sealed terminal feature of the substitute part affect compatibility?

A: No. Epoxy sealed terminals on the 7201P3YV71SE2 provide enhanced environmental protection and do not alter electrical performance or PC pin connection specifications. This feature is compatible with all existing circuit board designs and connector interfaces.

Q: Why is the original part classified as obsolete?

A: The 7201P3YV71ME2 is no longer in active production. The 7201P3YV71SE2 represents the current production equivalent within the C&K 7000 series, offering improved compliance and environmental sealing while maintaining full functional equivalence.

Q: Are there any compliance differences between the two parts?

A: The 7201P3YV71SE2 is RoHS compliant, while the 7201P3YV71ME2 is RoHS non-compliant. For applications subject to RoHS requirements, the substitute part is the appropriate selection. Both parts carry identical ECCN (EAR99) and HTSUS classifications.
