• Drive Voltage: 10V gate drive compatibility
• Gate Threshold Voltage (Vgs(th)): 4V nominal
• Maximum Gate Voltage (Vgs): ±20V tolerance
• Operating Temperature Range: -55°C to 175°C minimum

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-252-3 DPAK (2 Leads + Tab), SC-63
• Moisture Sensitivity Level: MSL 1 or equivalent

Regulatory Compliance:

• RoHS3 Compliance required

Engineering Selection Recommendations

BUK7214-75B,118 as Primary Substitute:

The BUK7214-75B,118 from Nexperia USA Inc. is the manufacturer-recommended substitute for the IRFR2307ZPBF. This device maintains electrical equivalence across all critical parameters while providing enhanced performance characteristics:

• Drain current capacity of 70A exceeds the 42A requirement of the original part
• Maximum on-resistance of 14 mOhm is lower than the 16 mOhm specification, resulting in reduced power dissipation
• Gate charge of 41 nC is significantly lower than 75 nC, enabling faster switching operation
• Power dissipation rating of 158W provides additional thermal margin compared to 110W

Both devices share identical voltage ratings (75V Vdss), gate drive voltage (10V), gate threshold voltage (4V), maximum gate voltage (±20V), and operating temperature range (-55°C to 175°C). Package compatibility is confirmed with both using TO-252-3 DPAK surface mount configuration.

Regulatory compliance is maintained: both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Availability Consideration:

The IRFR2307ZPBF is discontinued at DiGi Electronics with 18,800 pieces reported in stock. The BUK7214-75B,118 is listed as obsolete with 2,602 pieces in stock. Both parts face long-term availability constraints. For new designs, evaluation of additional substitute options from the cross-reference list (STD45NF75T4, IRFR2307ZTRLPBF, IPD50N06S214ATMA2, FDD16AN08A0) is recommended to ensure supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the BUK7214-75B,118 be used as a direct replacement for the IRFR2307ZPBF in existing designs?

A: Yes. Both devices are N-Channel MOSFETs with identical 75V Vdss ratings, 10V drive voltage, 4V gate threshold voltage, ±20V maximum gate voltage, and -55°C to 175°C operating temperature range. Both use TO-252-3 DPAK surface mount packaging. The BUK7214-75B,118 exceeds the original part's current and power dissipation specifications, making it suitable for direct substitution without circuit modification.

Q: What are the key differences between these two parts?

A: The BUK7214-75B,118 provides superior performance in three areas: continuous drain current (70A versus 42A), on-resistance (14 mOhm versus 16 mOhm), and gate charge (41 nC versus 75 nC). These differences result in lower power dissipation and faster switching characteristics. Maximum power dissipation is 158W compared to 110W. Input capacitance is slightly higher at 2612 pF versus 2190 pF.

Q: Are there any package compatibility concerns?

A: No. Both the IRFR2307ZPBF and BUK7214-75B,118 use identical TO-252-3 DPAK (2 Leads + Tab) surface mount packaging, designated as SC-63. Pin-to-pin compatibility is confirmed, allowing direct PCB footprint reuse.

Q: What is the significance of the lower gate charge in the substitute part?

A: Lower gate charge (41 nC versus 75 nC) reduces the energy required to switch the transistor on and off. This results in faster switching transitions, reduced switching losses, and lower heat generation during high-frequency operation. This is a performance advantage over the original part.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the IRFR2307ZPBF and BUK7214-75B,118 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory compliance is maintained with the substitute part.

Q: What is the difference between the product status designations?

A: The IRFR2307ZPBF is listed as discontinued at DiGi Electronics, indicating it has been removed from active distribution. The BUK7214-75B,118 is listed as obsolete, indicating the manufacturer has ceased production. Both statuses indicate limited availability through standard distribution channels. Existing inventory may be available from secondary sources or authorized distributors.

Q: Can the substitute part handle higher current applications than the original?

A: Yes. The BUK7214-75B,118 is rated for 70A continuous drain current compared to 42A for the IRFR2307ZPBF. This higher current rating allows the substitute to be used in applications requiring greater current capacity while maintaining the same 75V voltage rating and package form factor.
