Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U41K19AV2LE is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be 4PDT to maintain electrical functionality
• Current Rating: Must support minimum 5A (AC/DC)
• Voltage Ratings: Must support minimum 120V AC and 28V DC
• Mounting Type: Must be through-hole, right-angle configuration
• Actuator Type & Length: Must be locking lever with 18.59mm length for mechanical compatibility
• Termination Style: Must use PC Pin termination
• Operating Temperature: Must support -30°C to 85°C range
• Electrical Life: Must meet or exceed 100,000 cycles

The U41K19AV2RE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved supply availability.

Engineering Selection Recommendations

The U41K19AV2RE is the recommended substitute for the obsolete U41K19AV2LE. Both components are manufactured by C&K within the same 7000 series and maintain identical electrical and mechanical specifications. The U41K19AV2RE offers the advantage of active product status, ensuring ongoing availability and supply chain support. Both parts maintain RoHS compliance and carry the same ECCN and HTSUS classifications, supporting seamless integration into existing designs and procurement workflows. The U41K19AV2RE is currently available with 1005 units in stock, compared to the limited remaining inventory of the obsolete U41K19AV2LE.

Frequently Asked Questions (FAQ)

Q: Can the U41K19AV2RE be used as a direct replacement for the U41K19AV2LE in existing designs?

A: Yes. Both components share identical circuit configuration (4PDT), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (through-hole, right-angle), actuator specifications (locking lever, 18.59mm), and termination style (PC Pin). No design modifications are required.

Q: What is the primary difference between these two parts?

A: The U41K19AV2LE is classified as obsolete, while the U41K19AV2RE maintains active product status. The U41K19AV2RE also shows REACH Affected status compared to REACH Unaffected for the main part, though both maintain equivalent RoHS compliance.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts feature identical mounting type (through-hole, right-angle), actuator type (locking lever), and actuator length (18.59mm), ensuring mechanical compatibility with existing PCB layouts and panel cutouts.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the U41K19AV2LE and U41K19AV2RE operate across the identical temperature range of -30°C to 85°C.

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

A: Both components are rated for 100,000 electrical cycles, providing equivalent reliability and service life expectations.

Q: Are there packaging or MSL (Moisture Sensitivity Level) differences?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
