IRFR2607ZPBF N-Channel MOSFET Equivalent & Substitute Parts
Part Overview
The IRFR2607ZPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 75V drain-to-source voltage with 42A continuous drain current at 25°C. This device is part of the HEXFET® series and is housed in a TO-252-3 DPAK surface mount package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the original electrical specifications and mechanical package requirements.

Substitute Part Grouping Explanation
Substitution of the IRFR2607ZPBF requires strict adherence to the following electrical and mechanical parameters:
Critical Substitution Criteria:
- Drain-to-Source Voltage (Vdss) must be equal to or greater than 75V
- Continuous Drain Current (Id) must be equal to or greater than 42A at 25°C
- On-Resistance (Rds On) must not exceed the original specification to maintain thermal performance
- Package type must be TO-252-3 DPAK or mechanically equivalent
- Operating temperature range must encompass -55°C to 175°C
- FET type must be N-Channel MOSFET technology
The AOD442 is identified as a manufacturer-recommended substitute. However, this part exhibits reduced electrical ratings compared to the IRFR2607ZPBF and does not meet the primary substitution criteria for voltage and current specifications.

Engineering Selection Recommendations
IRFR2607ZPBF Status: Discontinued at DiGi Electronics. ROHS3 compliant. REACH unaffected. Moisture sensitivity level 1 (unlimited).
AOD442 Status: Not for new designs. ROHS3 compliant. REACH unaffected. Moisture sensitivity level 1 (unlimited).
The AOD442 does not qualify as a direct substitute for the IRFR2607ZPBF based on provided electrical specifications. The AOD442 exhibits a lower Vdss rating (60V versus 75V) and reduced continuous drain current (37A versus 42A at Tc). These parameter reductions indicate the AOD442 is unsuitable for applications requiring the full electrical performance envelope of the IRFR2607ZPBF.
For applications where the IRFR2607ZPBF is discontinued, component selection must prioritize parts with equal or superior electrical ratings. Alternative N-Channel MOSFETs in TO-252-3 DPAK packaging with Vdss ≥ 75V and Id ≥ 42A (Tc) should be evaluated against the original specifications.
Frequently Asked Questions (FAQ)
Q: Can the AOD442 be used as a direct replacement for the IRFR2607ZPBF?
A: No. The AOD442 has a maximum Vdss of 60V compared to the IRFR2607ZPBF's 75V rating, and a reduced continuous drain current of 37A (Tc) versus 42A (Tc). These reduced electrical ratings make it unsuitable for applications designed around the original part's specifications.
Q: What are the critical parameters for substituting the IRFR2607ZPBF?
A: Substitutes must meet or exceed: Vdss ≥ 75V, Id ≥ 42A at 25°C (Tc), Rds On ≤ 22mOhm at comparable test conditions, operating temperature range -55°C to 175°C, and TO-252-3 DPAK package compatibility.
Q: Are the packages of IRFR2607ZPBF and AOD442 compatible?
A: Both parts use TO-252-3 DPAK surface mount packages with identical mechanical dimensions (2 leads + tab, SC-63). Package compatibility is confirmed, but electrical parameter mismatches prevent substitution.
Q: What is the impact of the AOD442's higher gate charge (68nC vs. 51nC)?
A: Higher gate charge increases driver circuit power dissipation and switching losses. This parameter difference reflects different internal device architecture and must be evaluated in the context of the complete circuit design.
Q: Why is the IRFR2607ZPBF discontinued?
A: Product discontinuation is determined by the manufacturer and distributor. The part remains available through inventory channels but is no longer in active production at DiGi Electronics.
Q: Are both parts RoHS3 compliant?
A: Yes. Both the IRFR2607ZPBF and AOD442 are ROHS3 compliant with moisture sensitivity level 1 (unlimited) and REACH unaffected status.
