Substitute Part Grouping Explanation

Substitute parts for the BAS85-M-18 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mA
• Current - Reverse Leakage @ Vr: ≤ 2.3 µA @ 25 V
• Capacitance @ Vr, F: 10 pF @ 1V, 1MHz
• Operating Temperature - Junction (Max): 125°C

Mechanical Compatibility Criteria:

• Package / Case: DO-213AC, MINI-MELF, SOD-80
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance & Certification:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitute parts meet all electrical performance specifications and mechanical package requirements. Packaging format (Tape & Reel or Cut Tape) represents a logistics variation that does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

BAS85,115 (Nexperia USA Inc.)

This substitute part is electrically equivalent to the BAS85-M-18 across all critical parameters. The reverse leakage current specification of 2.3 µA at 25 V is within acceptable tolerance relative to the 2 µA specification of the main part. Both parts maintain identical voltage ratings, current capacity, and forward voltage characteristics. The BAS85,115 carries Active product status, ROHS3 compliance, and MSL 1 rating. The packaging format difference (Cut Tape & Digi-Reel® versus Tape & Reel) represents a supply chain variation without impact on component performance or mechanical fit.

BAS85,135 (Nexperia USA Inc.)

This substitute part is electrically equivalent to the BAS85-M-18 across all critical parameters. The reverse leakage current specification of 2.3 µA at 25 V is within acceptable tolerance relative to the 2 µA specification of the main part. Both parts maintain identical voltage ratings, current capacity, and forward voltage characteristics. The BAS85,135 carries Active product status, ROHS3 compliance, and MSL 1 rating. The packaging format (Tape & Reel) matches the main part configuration.

Both substitute parts are qualified for direct replacement based on electrical performance equivalence, mechanical package compatibility, and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the BAS85-M-18?

A: Substitute parts must match the following criteria: 30 V DC reverse voltage rating, 200 mA average rectified current, 800 mV maximum forward voltage at 100 mA, reverse leakage current not exceeding 2.3 µA at 25 V, 10 pF capacitance at 1V and 1MHz, DO-213AC/MINI-MELF/SOD-80 package configuration, surface mount mounting type, 125°C maximum junction temperature, ROHS3 compliance, and MSL 1 rating.

Q: Are the Nexperia BAS85,115 and BAS85,135 parts electrically identical to the Vishay BAS85-M-18?

A: Yes. Both Nexperia parts meet all electrical specifications of the BAS85-M-18. The reverse leakage current of 2.3 µA specified for the Nexperia parts is within acceptable tolerance of the 2 µA specification for the Vishay part. All other electrical parameters are identical.

Q: What is the difference between BAS85,115 and BAS85,135?

A: The primary difference is packaging format. The BAS85,115 is supplied in Cut Tape (CT) & Digi-Reel® format, while the BAS85,135 is supplied in Tape & Reel (TR) format. Both parts are electrically and mechanically equivalent. The packaging format selection depends on manufacturing process requirements and supply chain logistics.

Q: Can I use these substitute parts in automotive applications?

A: The BAS85-M-18 carries AEC-Q101 automotive qualification. The substitute parts (BAS85,115 and BAS85,135) are listed as Active products with ROHS3 compliance and MSL 1 rating. Confirmation of automotive qualification status for the Nexperia parts should be obtained from the manufacturer for applications requiring explicit AEC-Q101 certification.

Q: Does the package designation SOD-80 / MINI-MELF / DO-213AC refer to the same physical package?

A: Yes. SOD-80, MINI-MELF, and DO-213AC are equivalent designations for the same surface mount package configuration. All three substitute parts use this identical package format, ensuring mechanical compatibility in PCB assembly.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. No compliance or regulatory differences exist between the main part and substitute parts.
