Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ESD2B5.0MUT3G is determined by the following critical electrical and mechanical parameters:

Voltage Rating Criteria: The reverse standoff voltage (5V nominal) and clamping voltage characteristics define the primary substitution boundary. Substitute parts must maintain equivalent voltage protection levels to ensure circuit protection integrity.

Package and Mounting Compatibility: Physical package dimensions and mounting type determine mechanical fit within existing PCB designs. Substitutes must be compatible with the original mounting footprint or require documented PCB redesign.

Compliance and Certification: RoHS3 compliance, MSL rating, and REACH status ensure regulatory alignment and manufacturing process compatibility. All substitute parts must maintain equivalent compliance certifications.

Manufacturer Status: Active product status of substitute parts ensures long-term availability and manufacturing support, addressing the obsolescence of the original component.

The ESD5481MUT5G qualifies as a manufacturer-recommended substitute based on alignment with these core parameters.

Engineering Selection Recommendations

The ESD5481MUT5G is designated as the manufacturer-recommended substitute for the obsolete ESD2B5.0MUT3G. Selection of this substitute is supported by the following factors:

Product Status Alignment: The ESD5481MUT5G maintains active product status with onsemi, ensuring continued manufacturing support, availability, and technical documentation. This directly addresses the obsolescence limitation of the original component.

Regulatory Compliance: Both components maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification. This ensures equivalent regulatory positioning and manufacturing process compatibility.

Voltage Protection Characteristics: The substitute part specifies a 5V maximum reverse standoff voltage with 5.7V minimum breakdown voltage, aligning with the 5V nominal rating of the original component. The 12.4V clamping voltage provides defined transient suppression performance.

Packaging and Availability: The ESD5481MUT5G is available in high-volume inventory (820,200 pcs), packaged in Tape & Reel format, supporting production-scale deployment. The 0201 package (2-X3DFN) represents a standard surface-mount form factor.

Frequently Asked Questions (FAQ)

Q: Why is the ESD2B5.0MUT3G obsolete? A: The ESD2B5.0MUT3G is classified as obsolete by onsemi. The ESD5481MUT5G is the active replacement part, ensuring continued availability and manufacturing support.

Q: What are the key electrical parameters for substitution? A: The critical parameters are reverse standoff voltage (5V nominal), breakdown voltage (5.7V minimum), and clamping voltage (12.4V maximum).
