0402ESDA-MLPT Equivalent & Substitute Parts

Part Overview

The 0402ESDA-MLPT is a Transient Voltage Suppressors (TVS) device manufactured by Eaton - Electronics Division. This polymer-based TVS operates at 35V clamping voltage and is designed for general-purpose circuit protection applications in surface mount configurations. The device is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0402ESDA-MLPT is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 35V (exact match required)
• Technology: Polymer (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Series: PolySurg (exact match required)
• Applications: General Purpose (exact match required)

The substitute part 0402ESDA-MLP1 meets all these criteria and is therefore a direct functional equivalent. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 0402ESDA-MLP1 is the direct substitute for the obsolete 0402ESDA-MLPT. Selection of the substitute part is based on the following engineering factors:

Product Status: The 0402ESDA-MLPT is classified as obsolete. The 0402ESDA-MLP1 maintains active product status with full manufacturer support and availability.

Compliance Certification: The 0402ESDA-MLP1 is ROHS3 compliant, whereas the main part is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part satisfies regulatory requirements. The 0402ESDA-MLP1 also carries REACH Unaffected status.

Electrical and Mechanical Equivalence: Both parts are identical across all functional parameters including voltage rating, technology platform, circuit count, mounting configuration, and package specification.

Packaging and Availability: The 0402ESDA-MLP1 is supplied in Cut Tape (CT) and Digi-Reel® packaging with significantly higher inventory availability (330,100 pieces in stock versus 920 pieces for the obsolete part).

Frequently Asked Questions (FAQ)

Q: Can the 0402ESDA-MLP1 be used as a direct replacement for the 0402ESDA-MLPT in existing designs?

A: Yes. The 0402ESDA-MLP1 is electrically and mechanically equivalent to the 0402ESDA-MLPT across all specified parameters. Both devices operate at 35V clamping voltage, use polymer technology, feature single-circuit configuration, and are packaged in 0402 (1005 Metric) surface mount format.

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

A: The primary differences are product status and compliance certification. The 0402ESDA-MLPT is obsolete and RoHS non-compliant. The 0402ESDA-MLP1 is an active product with ROHS3 compliance and REACH Unaffected status. Functionally, both parts are identical.

Q: Are there packaging differences between the two parts?

A: The 0402ESDA-MLPT packaging specification is not detailed in available data. The 0402ESDA-MLP1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Both parts use the same 0402 (1005 Metric) component package.

Q: Why should I transition from the 0402ESDA-MLPT to the 0402ESDA-MLP1?

A: The 0402ESDA-MLPT is obsolete, which creates long-term supply risk. The 0402ESDA-MLP1 is an active product with robust inventory levels and manufacturer support. Additionally, the substitute part meets current RoHS3 compliance requirements.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts share identical electrical specifications: 35V clamping voltage, polymer technology, single-circuit design, and general-purpose application suitability.
