Substitute Part Grouping Explanation

Substitution of the SS3003CH-TL-E is determined by electrical and mechanical parameter equivalence within the Schottky diode category. The critical parameters that define substitutability are:

• Voltage Rating: DC reverse voltage of 30V maximum
• Current Rating: Average rectified current of 3A
• Forward Voltage Drop: 420 mV maximum at 3A forward current
• Reverse Recovery Time: 20 ns fast recovery characteristic
• Reverse Leakage Current: 1.4 mA at 15V reverse bias
• Package Type: SOT-23-6 surface mount configuration
• Temperature Range: -55°C to 125°C junction operating range
• Technology: Schottky diode construction

The substitute part SS3003CH-TL-W maintains identical electrical specifications across all critical parameters and shares the same base product number (SS3003), confirming functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The SS3003CH-TL-W is the direct equivalent substitute for the SS3003CH-TL-E. Both components are manufactured by onsemi and share identical electrical specifications, thermal characteristics, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction is product status: the SS3003CH-TL-E is designated "Not For New Designs," while the SS3003CH-TL-W maintains "Active" status. This status difference reflects manufacturing lifecycle positioning rather than technical capability. The SS3003CH-TL-W is suitable for applications requiring ongoing component availability and supply chain continuity.

Both parts meet the same regulatory requirements and environmental compliance standards. The SOT-23-6 surface mount package is consistent across both variants, ensuring mechanical and thermal compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SS3003CH-TL-W replace SS3003CH-TL-E in existing designs?

A: Yes. The SS3003CH-TL-W provides identical electrical performance across all specified parameters, including voltage rating, current capacity, forward voltage drop, reverse recovery time, and leakage current. The surface mount package and thermal characteristics are equivalent.

Q: What is the difference between SS3003CH-TL-E and SS3003CH-TL-W?

A: The components are electrically and mechanically identical. The primary difference is product lifecycle status: SS3003CH-TL-E is "Not For New Designs," while SS3003CH-TL-W is "Active." Both are ROHS3 compliant and manufactured by onsemi.

Q: Are there package compatibility concerns?

A: No. Both parts use the SOT-23-6 surface mount package. The SS3003CH-TL-E specifies "SOT-23-6 Thin, TSOT-23-6," and the SS3003CH-TL-W specifies "SOT-23-6." These designations refer to the same physical package footprint suitable for standard PCB assembly processes.

Q: What are the critical electrical parameters for substitution?

A: Substitution is valid when the following parameters match: 30V DC reverse voltage rating, 3A average rectified current, 420 mV forward voltage drop at 3A, 20 ns reverse recovery time, and 1.4 mA reverse leakage current at 15V. The SS3003CH-TL-W meets all these specifications.

Q: Are compliance certifications equivalent?

A: Yes. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). No additional qualification is required from a regulatory standpoint.

Q: What is the operating temperature range?

A: Both parts operate across a junction temperature range of -55°C to 125°C, providing equivalent thermal performance in all application environments.
