Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAW101-7 (Diodes Incorporated)

The BAW101-7 is the recommended substitute for the obsolete BAW101E6433HTMA1. Both devices share identical electrical ratings for reverse voltage (300 V), average rectified current (250 mA per diode), and reverse leakage current (150 nA @ 250 V). Both are packaged in TO-253-4/TO-253AA Surface Mount configuration and comply with ROHS3 and REACH requirements.

The BAW101-7 carries Active product status, ensuring long-term availability and supply chain continuity. Both devices maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating special handling requirements.

The BAW101-7 exhibits improved electrical performance with lower forward voltage drop (1.1 V vs. 1.3 V @ 100 mA) and faster reverse recovery time (50 ns vs. 1 µs), classified as Fast Recovery versus Standard Recovery. These performance enhancements are compatible with applications designed for the BAW101E6433HTMA1 and provide operational margin improvements.

Pin-to-pin compatibility and footprint equivalence are maintained across both devices, supporting direct substitution in existing PCB designs without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the BAW101-7 directly replace the BAW101E6433HTMA1 in existing designs?

A: Yes. Both devices share identical package configuration (TO-253-4/TO-253AA), mounting type (Surface Mount), and critical electrical ratings (300 V reverse voltage, 250 mA average rectified current per diode). Pin-to-pin compatibility is maintained, supporting direct PCB substitution without layout changes.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The BAW101E6433HTMA1 is classified as Obsolete, indicating discontinued manufacturing and limited remaining inventory. The BAW101-7 is Active, ensuring ongoing production, established supply chain availability, and long-term component sourcing capability for new and ongoing production requirements.

Q: How do the electrical performance differences affect circuit operation?

A: The BAW101-7 exhibits lower forward voltage drop (1.1 V vs. 1.3 V @ 100 mA) and significantly faster reverse recovery time (50 ns vs. 1 µs). These characteristics represent performance improvements that are compatible with applications designed for the BAW101E6433HTMA1. Circuits will operate within specified parameters with the substitute part.

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

A: No. Both devices are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification. Compliance and environmental handling requirements are identical.

Q: What is the operating temperature range difference?

A: The BAW101E6433HTMA1 specifies maximum junction temperature of 150°C. The BAW101-7 specifies operating temperature range of -65°C to 150°C. The BAW101-7 provides extended low-temperature operation capability while maintaining the same maximum temperature rating.

Q: Are there any package or footprint considerations for substitution?

A: Both devices use identical package designations (TO-253-4, TO-253AA) and Surface Mount mounting type. Supplier device packages (PG-SOT-143-3D for BAW101E6433HTMA1 and SOT-143 for BAW101-7) are footprint-compatible. No PCB redesign is required for substitution.
