Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMDB05CE3/TR13 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6V
• Voltage - Clamping (Max) @ Ipp: 11V
• Current - Peak Pulse (8/20µs): 5A minimum
• Power - Peak Pulse: 300W minimum
• Bidirectional Channels: 4

Mechanical Compatibility Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-SO

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts are classified into two categories: Direct Equivalents (identical electrical and mechanical specifications) and Similar Parts (matching core electrical parameters with documented parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (Microchip Technology):

SMDA05C-4-2E3/TR7 and SMDA05C/TR7 are direct electrical and mechanical equivalents to SMDB05CE3/TR13. Both parts maintain identical voltage ratings, current specifications, and thermal operating ranges. The primary distinction between these parts is packaging format: SMDA05C-4-2E3/TR7 is supplied in Tape & Reel format, while SMDA05C/TR7 is supplied in Cut Tape format. Both parts carry active product status, full RoHS3 compliance, and MSL 1 rating. Selection between these options depends on procurement quantity requirements and assembly process specifications.

Similar Substitute (Semtech Corporation):

SMDA05C.TBT is a cross-manufacturer substitute manufactured by Semtech Corporation. This part maintains electrical compatibility for voltage parameters (5V standoff, 6V breakdown, 11V clamping) and mechanical compatibility (8-SOIC package, surface mount). The SMDA05C.TBT exhibits higher peak pulse current capability (17A versus 5A) and increased capacitance (350pF versus 200pF at 1MHz). The maximum operating temperature is reduced to 125°C compared to 150°C for Microchip parts. This part is suitable for applications where higher transient current handling is beneficial and the reduced upper temperature limit does not conflict with system requirements. Full RoHS3 compliance and MSL 1 rating are maintained.

All substitute parts carry active product status and meet specified compliance requirements for direct component selection without additional qualification testing.

Frequently Asked Questions (FAQ)

Q: Can SMDA05C-4-2E3/TR7 be used as a direct replacement for SMDB05CE3/TR13?

A: Yes. SMDA05C-4-2E3/TR7 is electrically and mechanically equivalent to SMDB05CE3/TR13. Both parts are manufactured by Microchip Technology and share identical voltage ratings (5V standoff, 6V breakdown, 11V clamping), current specifications (5A peak pulse), power rating (300W), capacitance (200pF @ 1MHz), and operating temperature range (-55 to 150°C). Both are supplied in Tape & Reel packaging and meet RoHS3 compliance with MSL 1 rating.

Q: What is the difference between SMDA05C-4-2E3/TR7 and SMDA05C/TR7?

A: The electrical and mechanical specifications are identical between these two parts. The difference is packaging format: SMDA05C-4-2E3/TR7 is supplied in Tape & Reel (TR) format, while SMDA05C/TR7 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and procurement volume.

Q: Can SMDA05C.TBT from Semtech Corporation replace SMDB05CE3/TR13?

A: SMDA05C.TBT is compatible for voltage and package specifications but exhibits parameter differences. The Semtech part provides higher peak pulse current (17A versus 5A) and increased capacitance (350pF versus 200pF at 1MHz). The maximum operating temperature is 125°C instead of 150°C. This part is suitable when higher transient current handling is required and the reduced upper temperature limit is acceptable for the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SMDA05C-4-2E3/TR7, SMDA05C/TR7, and SMDA05C.TBT are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts carry REACH Unaffected status.

Q: What determines whether a part can substitute for SMDB05CE3/TR13?

A: Substitution is determined by matching the following parameters: Voltage - Reverse Standoff (5V), Voltage - Breakdown (6V minimum), Voltage - Clamping (11V maximum), Current - Peak Pulse (5A minimum for 8/20µs), Power - Peak Pulse (300W minimum), Bidirectional Channels (4), Package / Case (8-SOIC 0.154" width), Mounting Type (Surface Mount), and compliance certifications (RoHS3, MSL 1). Variations in secondary parameters such as capacitance or maximum operating temperature do not prevent substitution if core electrical and mechanical requirements are met.

Q: What is the inventory status of substitute parts?

A: SMDA05C-4-2E3/TR7 has 1813 pieces in stock, SMDA05C/TR7 has 853 pieces in stock, and SMDA05C.TBT has 8076 pieces in stock. The original SMDB05CE3/TR13 has 778 pieces in stock.
