Substitute Part Grouping Explanation

Substitution of the BAS7005WE6327HTSA1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

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
Operating Temperature - Junction (Max): 150°C
Mounting Type: Surface Mount

Package Considerations: Substitute parts are grouped into two categories based on package type:

SC-70, SOT-323 Package (Direct Pin-Compatible): Parts maintaining identical package footprint and pinout
TO-236-3, SC-59, SOT-23-3 Package (Functional Equivalent, Different Footprint): Parts with identical electrical specifications but different physical package requiring PCB layout modification

All substitute parts listed maintain the core electrical specifications of the original component while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Recommendation - Direct Pin-Compatible Substitutes (SC-70, SOT-323):

The BAS7005WH6327XTSA1 from Infineon Technologies is the primary equivalent substitute. This part maintains identical electrical specifications, package footprint, and pinout while offering active product status and ROHS3 compliance. Inventory availability is substantial at 34,421 pieces.

Alternative SC-70, SOT-323 substitutes include BAS70-05W,115 (Nexperia USA Inc.), BAS70W-05-7-F (Diodes Incorporated), BAS70-05W,135 (Nexperia USA Inc.), and BAS70-05WFILM (STMicroelectronics). All maintain identical electrical parameters and active product status with ROHS3 compliance. These parts enable direct PCB replacement without layout modification.

Secondary Recommendation - Functional Equivalent Substitutes (TO-236-3, SC-59, SOT-23-3):

The BAS70-05,215 (NXP USA Inc.) and BAS70-05,235 (Nexperia USA Inc.) provide functional electrical equivalence with identical voltage, current, and temperature ratings. These parts require PCB layout modification due to different package footprint. Both maintain active product status. BAS70-05,235 offers ROHS3 compliance.

Compliance Considerations:

All recommended active substitutes maintain REACH Unaffected status and ECCN EAR99 classification consistent with the original part. ROHS3 compliance is available across all active substitutes, supporting modern manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can BAS7005WH6327XTSA1 be used as a direct replacement for BAS7005WE6327HTSA1?

A: Yes. BAS7005WH6327XTSA1 maintains identical electrical specifications (70V reverse voltage, 70mA average rectified current, 1V forward voltage @ 15mA), diode configuration (1 pair common cathode), package type (SC-70, SOT-323), and pinout. No circuit modification is required.

Q: What is the difference between SC-70, SOT-323 and TO-236-3, SC-59, SOT-23-3 packages?

A: SC-70, SOT-323 and TO-236-3, SC-59, SOT-23-3 are different physical packages with different footprints and pin spacing. Parts in SC-70, SOT-323 package (BAS7005WH6327XTSA1, BAS70-05W,115, BAS70W-05-7-F, BAS70-05W,135, BAS70-05WFILM) are pin-compatible with the original part and require no PCB modification. Parts in TO-236-3, SC-59, SOT-23-3 package (BAS70-05,215, BAS70-05,235) require PCB layout redesign but provide identical electrical function.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant except BAS70-05,215, which does not specify RoHS status. ROHS3 compliance is confirmed for BAS7005WH6327XTSA1, BAS70-05W,115, BAS70W-05-7-F, BAS70-05W,135, BAS70-05WFILM, and BAS70-05,235.

Q: Why is the original BAS7005WE6327HTSA1 marked as obsolete?

A: The BAS7005WE6327HTSA1 is classified as obsolete product status. Active equivalent parts from multiple manufacturers (Infineon, Nexperia, Diodes Incorporated, STMicroelectronics, NXP) are available to support continued design and procurement requirements.

Q: What is the difference in reverse leakage current specifications among substitute parts?

A: The original BAS7005WE6327HTSA1 specifies 100 nA @ 50V reverse leakage current. Substitute parts BAS70-05W,115, BAS70-05W,135, BAS70-05,215, and BAS70-05,235 specify 10 µA @ 70V reverse leakage current. BAS70W-05-7-F and BAS70-05WFILM maintain 100 nA @ 50V specification. Both specifications are within acceptable operating parameters for this component category.

Q: Can I use BAS70-05,215 or BAS70-05,235 if my PCB is designed for SC-70, SOT-323 package?

A: No. BAS70-05,215 and BAS70-05,235 use TO-236-3, SC-59, SOT-23-3 package with different physical dimensions and pin spacing. These parts require PCB layout modification and cannot be used in existing SC-70, SOT-323 footprints.

Q: Which substitute part has the highest inventory availability?

A: BAS70W-05-7-F from Diodes Incorporated has the highest inventory availability at 68,300 pieces, followed by BAS7005WH6327XTSA1 at 34,421 pieces and BAS70-05WFILM at 32,100 pieces.
