BAS70LP-TP Equivalent & Substitute Parts

Part Overview

The BAS70LP-TP is a Schottky diode rated for 70V DC reverse voltage and 70mA average rectified current in a SOD-882 surface mount package, manufactured by Micro Commercial Co. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts maintain the core electrical specifications while offering improved availability through active product status from alternative manufacturers or enhanced performance characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70LP-TP is determined by strict equivalence in the following electrical and mechanical parameters:

Core Electrical Requirements:

• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io): 70 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical & Environmental Requirements:

• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these core requirements. Package variations (SOD-882, DFN1006-2L, 0402/SOD-923F) are acceptable provided the electrical specifications remain within tolerance and the component is surface mount compatible. Substitute parts may exhibit improved performance characteristics such as lower reverse leakage current, faster reverse recovery time, or extended operating temperature ranges, while maintaining backward compatibility with the original part's functional requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

BAS7002LE6327XTMA1 (Infineon Technologies) and BAS70L,315 (Nexperia USA Inc.) are recommended as primary substitutes. Both maintain the SOD-882 package footprint identical to the original BAS70LP-TP, ensuring direct PCB compatibility without layout modifications. Both are active products with ROHS3 compliance and MSL 1 rating. BAS7002LE6327XTMA1 offers superior reverse leakage performance (100 nA @ 50 V) and faster reverse recovery time (100 ps), while BAS70L,315 provides extended maximum junction temperature (150°C vs. 125°C).

Secondary Substitutes (Package Variation):

BAS70LP-7B (Diodes Incorporated), BAS70L2-TP (Micro Commercial Co), and CDBQR70 (Comchip Technology) are functionally equivalent but utilize 0402 (1006 Metric) packages instead of SOD-882. These substitutes require PCB layout redesign and are suitable only when design flexibility permits package migration. All three are active products with full compliance certifications. BAS70LP-7B offers the lowest forward voltage (960 mV @ 15 mA) and extended operating temperature range (-65°C to 150°C).

Compliance & Availability:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility. Substitute parts demonstrate significantly higher inventory availability compared to the obsolete BAS70LP-TP, supporting long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can BAS70LP-TP be directly replaced with any of the listed substitutes?

A: Direct replacement without PCB modification is limited to substitutes maintaining the SOD-882 package: BAS7002LE6327XTMA1 and BAS70L,315. These parts are pin-compatible and footprint-compatible. Substitutes with 0402 (1006 Metric) packages require PCB layout redesign.

Q: What is the primary reason for substituting the BAS70LP-TP?

A: The BAS70LP-TP is classified as obsolete. Substitution ensures design continuity and production support through active products from established manufacturers with confirmed inventory availability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original BAS70LP-TP.

Q: How do reverse leakage characteristics differ among substitutes?

A: Reverse leakage varies significantly. The original BAS70LP-TP specifies 100 µA @ 50 V. Substitutes range from 10 µA @ 70 V (BAS70L,315 and BAS70LP-7B) to 100 nA @ 50 V (BAS7002LE6327XTMA1 and CDBQR70). Lower leakage improves efficiency in low-power applications.

Q: Which substitute offers the best thermal performance?

A: BAS70LP-7B and BAS70L,315 both support maximum junction temperatures of 150°C, compared to 125°C for the original part and most other substitutes. This provides improved thermal margin in high-temperature environments.

Q: Can package size be changed during substitution?

A: Package changes from SOD-882 to 0402 (1006 Metric) require PCB redesign and are not considered direct substitutions. Such changes should be evaluated within the context of complete circuit redesign and re-qualification.

Q: What is the difference between BAS70L2-TP and BAS70LP-TP?

A: BAS70L2-TP is an active product variant with improved reverse leakage (200 nA @ 50 V vs. 100 µA @ 50 V) and faster reverse recovery time (5 ns). It uses a 0402 package instead of SOD-882, requiring layout modification.

Q: Are all substitutes available in the same packaging formats?

A: No. BAS70LP-TP and BAS7002LE6327XTMA1 use SOD-882 packages. BAS70L2-TP, BAS70LP-7B, and CDBQR70 use 0402 (1006 Metric) packages. BAS70L,315 uses SOD-882. Packaging format affects PCB compatibility and assembly requirements.

Q: Which substitute has the lowest forward voltage drop?

A: BAS70LP-7B specifies 960 mV @ 15 mA, compared to 1 V @ 15 mA for the original part and other substitutes. This 40 mV reduction may provide marginal efficiency improvement in power-sensitive applications.
