Substitute Part Grouping Explanation

Substitution of the BAS70-05-7-F-79 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io) (per Diode): 70 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
• Reverse Recovery Time (trr): 5 ns
• Operating Temperature - Junction: -55°C ~ 125°C
• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3

Allowable Variation:

• Current - Reverse Leakage @ Vr: 100 nA or 200 nA @ 50 V (both acceptable within Schottky diode specifications)
• Packaging format (Cut Tape, Tape & Reel, or Digi-Reel®)
• Manufacturer source (Diodes Incorporated, Taiwan Semiconductor Corporation, Comchip Technology, Micro Commercial Co)

All substitute parts listed maintain full electrical and mechanical compatibility with the original BAS70-05-7-F-79 specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAS70-05-7-F

The BAS70-05-7-F from Diodes Incorporated is the direct parametric equivalent to the BAS70-05-7-F-79. This part maintains identical electrical specifications and is currently in Active product status with substantial inventory availability (8184 units). As a product from the same manufacturer with the same base part number, this represents the most direct replacement path. The part is available in Cut Tape and Digi-Reel® packaging formats.

Secondary Substitutes: BAS70-05 RFG, BAS70-05-HF, BAS70-05-TP

All four substitute parts listed are parametrically equivalent and maintain full compatibility with the original specification. Selection among these alternatives should be based on:

1. Availability and Lead Time: BAS70-05-TP (Micro Commercial Co) offers the highest inventory level at 248,307 units, providing maximum supply security.

2. Reverse Leakage Specification: BAS70-05-7-F and BAS70-05 RFG specify 100 nA @ 50 V reverse leakage, matching the original part exactly. BAS70-05-HF and BAS70-05-TP specify 200 nA @ 50 V, which remains within acceptable Schottky diode performance parameters and does not impact circuit functionality for typical applications.

3. Packaging Requirements: All substitutes are available in Tape & Reel format. BAS70-05-7-F additionally offers Digi-Reel® packaging. Verify packaging compatibility with assembly equipment specifications.

4. Compliance and Certifications: All substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can BAS70-05-TP be used as a direct replacement for BAS70-05-7-F-79?

A: Yes. BAS70-05-TP is a parametric equivalent meeting all electrical and mechanical specifications. The only difference is the reverse leakage specification (200 nA vs. 100 nA @ 50 V), which remains within acceptable Schottky diode performance ranges and does not affect circuit operation in standard applications.

Q: What is the difference between the substitute parts in terms of reverse leakage current?

A: BAS70-05-7-F and BAS70-05 RFG specify 100 nA @ 50 V reverse leakage, identical to the original BAS70-05-7-F-79. BAS70-05-HF and BAS70-05-TP specify 200 nA @ 50 V. Both specifications are acceptable for Schottky diode arrays and do not impact circuit performance in typical rectification and switching applications.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts are packaged in TO-236-3, SC-59, SOT-23-3 Surface Mount packages with identical pin configurations and footprints. Packaging formats differ (Cut Tape, Tape & Reel, Digi-Reel®), but the physical component package remains consistent across all substitutes.

Q: Why is the original BAS70-05-7-F-79 marked as Obsolete?

A: The BAS70-05-7-F-79 is classified as Obsolete, indicating it is no longer in active production. However, equivalent parts from multiple manufacturers remain in Active status with full availability, ensuring design continuity and component supply for existing applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and manufacturing standards.

Q: Which substitute offers the best inventory availability?

A: BAS70-05-TP from Micro Commercial Co offers the highest inventory level at 248,307 units, providing maximum supply security and shortest lead times.

Q: Can I mix different manufacturers' parts in the same assembly?

A: Yes. All substitute parts are parametrically equivalent and interchangeable. Mixing manufacturers in the same assembly does not affect circuit performance, as all parts meet identical electrical and mechanical specifications.

Q: What is the significance of the "-7-F" designation in BAS70-05-7-F?

A: The "-7-F" designation indicates the specific variant and packaging format within the BAS70 base product family. The BAS70-05-7-F is the active production equivalent to the obsolete BAS70-05-7-F-79, with identical electrical performance.
