BAV99W H6433 Equivalent & Substitute Parts

Part Overview

The BAV99W H6433 is a general-purpose diode array manufactured by Infineon Technologies, configured as 1 pair series connection with 80 V reverse voltage rating and 200 mA average rectified current per diode. The device is housed in a surface mount SC-70, SOT-323 package. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAV99W H6433 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Series Connection
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 80 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 200 mA
• Speed Classification: Small Signal ≤ 200 mA (Io), Any Speed
• Operating Temperature - Junction (Max): Equal to or greater than 150°C

The three substitute parts listed below satisfy these mandatory criteria while maintaining functional equivalence in standard general-purpose diode array applications.

Parameter Comparison

Engineering Selection Recommendations

1PS302,115 (Nexperia USA Inc.)

This substitute maintains identical voltage and speed specifications to the BAV99W H6433. The current rating of 170 mA per diode is lower than the original 200 mA specification. The part is active and ROHS3 compliant. Suitable for applications where the 170 mA current capacity is sufficient.

BAV199W-7 (Diodes Incorporated)

This substitute provides a higher reverse voltage rating of 85 V compared to the original 80 V specification. The current rating of 140 mA per diode is lower than the original 200 mA specification. The reverse recovery time is specified as 3 µs, differing from the original 4 ns specification. The part is active and ROHS3 compliant with extended operating temperature range (-65°C ~ 150°C).

BAV99W-7-F (Diodes Incorporated)

This substitute provides a lower reverse voltage rating of 75 V compared to the original 80 V specification. The current rating of 150 mA per diode is lower than the original 200 mA specification. The forward voltage and reverse recovery time specifications match the original part. The part is active and ROHS3 compliant with extended operating temperature range (-65°C ~ 150°C).

All three substitutes are active products with current manufacturing status, addressing the obsolescence of the original BAV99W H6433 part.

Frequently Asked Questions (FAQ)

Q: Can the 1PS302,115 directly replace the BAV99W H6433?

A: The 1PS302,115 maintains the same package (SC-70, SOT-323), diode configuration (1 pair series connection), voltage rating (80 V), and speed classification. The current rating is 170 mA per diode versus 200 mA for the original part. Direct replacement is possible in applications where 170 mA current capacity is acceptable.

Q: What is the primary difference between BAV199W-7 and the original BAV99W H6433?

A: The BAV199W-7 has a higher reverse voltage rating (85 V versus 80 V) and lower current rating (140 mA versus 200 mA). The reverse recovery time is specified as 3 µs instead of 4 ns. Both use the same SC-70, SOT-323 package and 1 pair series connection configuration.

Q: Why does BAV99W-7-F have a lower voltage rating than the original?

A: The BAV99W-7-F is rated for 75 V reverse voltage, which is 5 V lower than the original BAV99W H6433 specification of 80 V. This part is suitable for applications with voltage requirements at or below 75 V.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1PS302,115, BAV199W-7, and BAV99W-7-F are all ROHS3 compliant. The original BAV99W H6433 RoHS status was not specified in the provided data.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts and the original BAV99W H6433 have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which substitute part has the widest operating temperature range?

A: Both BAV199W-7 and BAV99W-7-F specify an operating temperature range of -65°C ~ 150°C, compared to the original part's maximum junction temperature of 150°C.

Q: Can these parts be used interchangeably in all applications?

A: No. Selection must be based on the specific application requirements for reverse voltage, average rectified current, and operating temperature. The current ratings of the substitutes (140-170 mA) are lower than the original (200 mA), which may limit their use in high-current applications.
