Substitute Part Grouping Explanation

Substitution eligibility for the BDP947E6327HTSA1 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor Type: NPN (mandatory match)
Voltage - Collector Emitter Breakdown: minimum 45 V (equal or higher acceptable)
Current - Collector (Ic) (Max): minimum 3 A (equal or higher acceptable)
Package / Case: TO-261-4 or TO-261AA (mechanical compatibility required)
Mounting Type: Surface Mount (required)
Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Secondary Compatibility Parameters:

Operating Temperature: maximum 150°C or higher

Engineering Selection Recommendations

Full Current Rating Substitutes (3 A or Higher):

DNLS350E-13, FZT651QTA, FZT651TA, FZT651TC, and PBSS4350Z,135 maintain the full 3 A collector current rating of the original BDP947E6327HTSA1. These parts are recommended for applications requiring the complete current handling capability of the original design.

DNLS350E-13 and PBSS4350Z,135 provide voltage ratings of 50 V, exceeding the original 45 V specification. Both devices are RoHS3 compliant and carry REACH Unaffected status, matching the environmental compliance profile of the original part.

FZT651QTA, FZT651TA, and FZT651TC offer 60 V voltage ratings with enhanced frequency performance (175 MHz versus 100 MHz). FZT651QTA carries AEC-Q101 automotive qualification. All three variants are RoHS3 compliant and REACH Unaffected.

Reduced Current Rating Substitutes (1 A):

BCP54-10,135 and BCP54TA are rated for 1 A maximum collector current. These parts are suitable only for applications where the circuit design permits operation at reduced current levels. BCP54-10,135 carries AEC-Q100 automotive qualification. Both devices are RoHS3 compliant and REACH Unaffected.

Higher Current Rating Substitute (5 A):

FZT1051ATA is rated for 5 A maximum collector current, providing enhanced current handling beyond the original specification. This part operates at 40 V collector-emitter breakdown voltage, which is lower than the original 45 V rating. FZT1051ATA is RoHS3 compliant and REACH Unaffected.

Product Status Consideration:

All substitute parts listed carry Active product status, ensuring long-term availability and continued manufacturing support. The original BDP947E6327HTSA1 is classified as Obsolete, making substitution necessary for ongoing production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can BCP54-10,135 or BCP54TA be used as direct replacements for BDP947E6327HTSA1?

A: BCP54-10,135 and BCP54TA are electrically compatible with the BDP947E6327HTSA1 in terms of voltage rating (45 V) and package type (SOT-223). However, these parts are rated for 1 A maximum collector current, compared to the original 3 A rating. They are suitable only for applications where circuit design permits operation at 1 A or lower current levels.

Q: Which substitute part most closely matches the original BDP947E6327HTSA1 specifications?

A: PBSS4350Z,135 and DNLS350E-13 provide the closest electrical match. Both maintain the 3 A collector current rating and offer voltage ratings of 50 V, exceeding the original 45 V specification. PBSS4350Z,135 is manufactured by Nexperia USA Inc. and carries AEC-Q100 automotive qualification. DNLS350E-13 is manufactured by Diodes Incorporated and is RoHS3 compliant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 Compliant status. The original BDP947E6327HTSA1 does not specify RoHS compliance. All substitutes also carry REACH Unaffected status, matching the environmental compliance profile of the original part.

Q: What is the difference between FZT651QTA, FZT651TA, and FZT651TC?

A: All three parts share identical electrical specifications: 3 A collector current, 60 V voltage rating, 175 MHz transition frequency, and 100 minimum hFE. The differences are in packaging format and power rating. FZT651QTA is supplied in Cut Tape (CT) & Digi-Reel® format with 3 W power rating and carries AEC-Q101 automotive qualification. FZT651TA is supplied in Cut Tape (CT) format with 2 W power rating. FZT651TC is supplied in Tape & Reel (TR) format with 2 W power rating.

Q: Can FZT1051ATA be used in place of BDP947E6327HTSA1?

A: FZT1051ATA is electrically compatible in terms of package type (SOT-223-3) and mounting method (Surface Mount). However, the collector-emitter breakdown voltage is 40 V, which is lower than the original 45 V specification. FZT1051ATA is suitable only for applications where the circuit design operates at 40 V or lower. The part offers enhanced current handling at 5 A maximum collector current.

Q: What packaging differences exist among the substitute parts?

A: All substitute parts use SOT-223 or SOT-223-3 surface mount packages, which are mechanically compatible with the original TO-261-4 and TO-261AA package designations. Packaging format variations include Tape & Reel (TR), Cut Tape (CT), and Cut Tape & Digi-Reel® options. These format differences affect supply and handling but do not impact electrical or mechanical compatibility.

Q: Are substitute parts available in sufficient inventory?

A: All substitute parts listed carry Active product status with documented inventory levels ranging from 10,010 to 45,760 pieces in stock, ensuring availability for production and field replacement applications.
