Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ET01LD1V3ME is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-On
• Mounting Type: Through Hole
• Actuator Type: Standard Round
• Actuator Length: 8.13mm
• Termination Style: PC Pin
• Ingress Protection: IP57
• Operating Temperature Range: -30°C ~ 85°C
• Electrical Life: 60,000 Cycles
• Base Product Number: ET01LD

Allowable Parameter Variations:

• Current Rating: May be lower than original specification
• Voltage Rating (AC): May be lower than original specification
• Voltage Rating (DC): Must remain at 28 V or higher
• Product Status: Must be Active
• RoHS Compliance: May be upgraded to ROHS3
• Packaging: May differ from original

The ET01LD1V3SE meets all mandatory matching parameters while operating within acceptable electrical parameter ranges for toggle switch SPDT applications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The ET01LD1V3SE is a direct functional substitute for the obsolete ET01LD1V3ME within defined electrical parameter boundaries. Both components share identical mechanical form factors, mounting configurations, and environmental protection ratings.

Critical Selection Criteria:

1. Current Requirement Analysis: The ET01LD1V3SE is rated for 3A (AC/DC) compared to the original 7.5A rating. Component selection must confirm that circuit current demands do not exceed 3A. Applications requiring current levels between 3A and 7.5A cannot use this substitute.

2. AC Voltage Requirement Analysis: The ET01LD1V3SE is rated for 120V AC compared to the original 125V AC rating. Component selection must confirm that AC voltage levels do not exceed 120V. Applications requiring AC voltage levels between 120V and 125V cannot use this substitute.

3. DC Voltage Compatibility: Both components maintain identical 28V DC rating, ensuring full compatibility for DC applications.

4. Compliance Status: The ET01LD1V3SE carries ROHS3 compliance and REACH Affected designation, representing an upgrade from the original RoHS Compliant status. This substitution improves regulatory compliance posture for new designs.

5. Product Availability: The ET01LD1V3SE maintains Active product status with confirmed inventory availability (712 Pcs), ensuring reliable long-term sourcing compared to the Obsolete ET01LD1V3ME.

Frequently Asked Questions (FAQ)

Q: Can the ET01LD1V3SE directly replace the ET01LD1V3ME in all applications?

A: The ET01LD1V3SE functions as a direct mechanical and electrical substitute only for applications operating at or below 3A current and 120V AC voltage. Applications exceeding these electrical parameters require alternative component selection.

Q: What are the primary differences between these two toggle switches?

A: The primary differences are current rating (7.5A versus 3A) and AC voltage rating (125V versus 120V). All other parameters including circuit configuration, mounting type, actuator dimensions, termination style, ingress protection, and operating temperature range are identical.

Q: Why is the ET01LD1V3ME classified as Obsolete?

A: The ET01LD1V3ME carries Obsolete product status, indicating that C&K has discontinued manufacturing and support for this specific part number. The ET01LD1V3SE represents the active equivalent within the ET series.

Q: Are there packaging differences between these components?

A: The ET01LD1V3ME packaging is listed as unspecified, while the ET01LD1V3SE is supplied in Tray packaging. This difference does not affect functional compatibility but may impact procurement and handling procedures.

Q: Does the ET01LD1V3SE meet the same environmental protection standards?

A: Yes. Both components maintain identical IP57 ingress protection rating (Dust Protected, Waterproof) and identical operating temperature range of -30°C to 85°C, ensuring equivalent environmental performance.

Q: What compliance certifications apply to the ET01LD1V3SE?

A: The ET01LD1V3SE carries ROHS3 Compliant status and is REACH Affected. These certifications represent an upgrade from the original RoHS Compliant designation of the ET01LD1V3ME.

Q: How many electrical cycles are rated for the ET01LD1V3SE?

A: The ET01LD1V3SE maintains the same 60,000 cycle electrical life rating as the original ET01LD1V3ME, ensuring equivalent operational durability.

Q: Is the actuator length identical between these components?

A: Yes. Both the ET01LD1V3ME and ET01LD1V3SE feature an 8.13mm standard round actuator length, ensuring identical panel mounting and user interface characteristics.
