Key Parameters

Substitute Part Grouping Explanation

Substitution of the E221SD1AV3LE is based on strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current and Voltage Ratings: 1A (AC/DC), 120V AC, 28V DC specifications must be matched
• Mounting and Mechanical Interface: Through hole, right-angle, vertical orientation with round plunger actuator
• Termination: PC pin termination required
• Operating Environment: Temperature range -30°C to 75°C and electrical life of 60,000 cycles
• Compliance: RoHS and REACH compliance status

The E221SD1AV3RE qualifies as a direct substitute based on identical electrical specifications, mechanical configuration, and environmental ratings. The primary distinction is product status: E221SD1AV3RE is active and available, whereas E221SD1AV3LE is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The E221SD1AV3RE is the qualified substitute for the obsolete E221SD1AV3LE. Both parts maintain identical electrical performance, mechanical interface, and environmental specifications. The E221SD1AV3RE carries active product status with confirmed inventory availability (865 pcs), ensuring supply chain continuity.

Both parts satisfy RoHS and REACH compliance requirements. The E221SD1AV3RE is supplied in bulk packaging, whereas the E221SD1AV3LE was supplied with standard packaging. This packaging difference does not affect functional or mechanical compatibility.

Selection of the E221SD1AV3RE eliminates obsolescence risk while preserving full electrical and mechanical compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the E221SD1AV3RE directly replace the E221SD1AV3LE without PCB modifications?

A: Yes. Both parts share identical mounting type (through hole, right angle, vertical), PC pin termination, and mechanical dimensions. No PCB layout changes are required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts operate at 1A (AC/DC), 120V AC, and 28V DC with DPDT configuration and On-Mom switch function. Electrical life is 60,000 cycles for both.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. E221SD1AV3LE is obsolete, while E221SD1AV3RE is active and currently available. All functional and mechanical specifications are equivalent.
