BDP953E6327HTSA1 Equivalent & Substitute Parts

Part Overview

The BDP953E6327HTSA1 is an NPN bipolar junction transistor manufactured by Infineon Technologies, rated for 100V collector-emitter breakdown voltage and 3A maximum collector current. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and production continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating packaging and availability constraints.

Substitute Part Grouping Explanation

Substitution of the BDP953E6327HTSA1 is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

Transistor Type: NPN (mandatory match)
Voltage - Collector Emitter Breakdown: 100V minimum (equal or higher acceptable)
Current - Collector (Ic) (Max): 3A minimum (equal or higher acceptable)
Vce Saturation: 500mV or lower at specified test conditions
DC Current Gain (hFE): 100 minimum at specified conditions
Mounting Type: Surface Mount (mandatory match)
Package / Case: TO-261-4 or TO-261AA compatible (mandatory match)

Secondary Considerations:

Power dissipation capability (5W reference)
Transition frequency (100MHz reference)
Operating temperature range (150°C maximum junction temperature)
Product status (active preferred for long-term availability)
Compliance certifications (RoHS, REACH status)

Substitute parts are grouped by their ability to meet or exceed the primary electrical specifications while maintaining package compatibility. Parts with higher current ratings or lower saturation voltages are acceptable as direct replacements. Parts with lower current ratings or higher saturation voltages do not meet substitution criteria.

Engineering Selection Recommendations

Full Electrical Compatibility (Direct Replacement):

FZT653TA and FZT653TC meet all primary substitution criteria. Both parts match the 100V breakdown voltage, achieve 2A collector current (within the 3A specification), and maintain 500mV saturation voltage at the same test conditions as the BDP953E6327HTSA1. Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. FZT653TA is supplied in Cut Tape & Digi-Reel packaging, while FZT653TC is supplied in Tape & Reel format. Selection between these two depends on procurement and assembly requirements.

Higher Current Capability (Suitable for Derating Applications):

FZT853TA provides 6A collector current with improved saturation characteristics (340mV @ 500mA, 5A), exceeding the original specification. This part is suitable for applications where additional current margin or lower saturation voltage is beneficial. PBSS306NZ,135 provides 5.1A collector current with superior saturation voltage (300mV @ 255mA, 5.1A) and includes automotive-grade qualification (AEC-Q100), making it appropriate for automotive or high-reliability applications.

Lower Current Capability (Not Recommended):

FZT493TA and PBSS8110Z,135 provide only 1A maximum collector current, which is insufficient for the 3A specification of the BDP953E6327HTSA1. These parts do not meet substitution criteria and should not be selected for direct replacement.

Compliance and Availability:

All active substitute parts are ROHS3 compliant and REACH unaffected. PBSS306NZ,135 and PBSS8110Z,135 carry automotive-grade qualification (AEC-Q100), suitable for automotive applications. All substitute parts maintain the same MSL rating (1 - Unlimited) as the original component.

Frequently Asked Questions (FAQ)

Q: Can FZT493TA replace the BDP953E6327HTSA1?

A: No. FZT493TA is rated for 1A maximum collector current, which is below the 3A requirement of the BDP953E6327HTSA1. This part does not meet the primary substitution criterion for current capacity.

Q: What is the difference between FZT653TA and FZT653TC?

A: Both parts are electrically identical NPN transistors with 100V breakdown voltage and 2A collector current. The difference is packaging: FZT653TA is supplied in Cut Tape & Digi-Reel format, while FZT653TC is supplied in Tape & Reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Why is FZT853TA acceptable as a substitute despite having 6A rating instead of 3A?

A: FZT853TA exceeds the minimum current requirement (6A > 3A) and maintains all other electrical specifications within acceptable ranges. Higher current rating provides design margin and does not compromise compatibility. The part is electrically suitable for applications designed for 3A operation.

Q: Can I use PBSS306NZ,135 in non-automotive applications?

A: Yes. PBSS306NZ,135 is an active product with automotive-grade qualification (AEC-Q100), but this qualification does not restrict use to automotive applications. The part meets all electrical specifications for the BDP953E6327HTSA1 and is suitable for general industrial applications.

Q: What does "REACH Unaffected" mean?

A: REACH Unaffected indicates that the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory restrictions. All substitute parts listed carry this status, ensuring regulatory compliance across markets.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (FZT493TA, FZT653TA, FZT653TC, FZT853TA, PBSS306NZ,135, PBSS8110Z,135) are ROHS3 compliant. The original BDP953E6327HTSA1 does not specify RoHS status due to its obsolete classification.

Q: What is the significance of Vce Saturation voltage in substitution?

A: Vce Saturation determines the voltage drop across the transistor in saturated (fully conducting) state. Lower saturation voltage reduces power dissipation and heat generation. The BDP953E6327HTSA1 specifies 500mV maximum at 200mA base current and 2A collector current. Substitute parts with equal or lower saturation voltage at comparable test conditions are acceptable.

Q: Why is the operating temperature range different for some substitutes?

A: The BDP953E6327HTSA1 specifies only maximum junction temperature (150°C). Active substitute parts from Diodes Incorporated (FZT series) specify full operating range (-55°C to 150°C), providing additional environmental specification detail. This does not affect substitution suitability; the maximum temperature specification remains compatible.

Q: Can I substitute based on package type alone?

A: No. Package compatibility (TO-261-4, TO-261AA) is necessary but not sufficient for substitution. All electrical parameters must also be verified. A part with correct packaging but insufficient current rating or higher saturation voltage is not a valid substitute.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without special moisture control measures and does not require baking before reflow soldering. All listed parts carry this rating.
