Substitute Part Grouping Explanation

Substitute parts for the IRLZ14STRR are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

FET Type: N-Channel (identical architecture)
Drain-to-Source Voltage (Vdss): 60V (identical maximum rating)
Continuous Drain Current (Id): 10A @ 25°C (identical current rating)
On-State Resistance (Rds On): 200 mOhm @ 6A, 5V (identical conduction specification)
Gate Threshold Voltage (Vgs(th)): 2V @ 250µA (identical gate drive threshold)
Gate Charge (Qg): 8.4 nC @ 5V (identical switching charge)
Input Capacitance (Ciss): 400 pF @ 25V (identical input impedance)
Power Dissipation: 3.7W (Ta), 43W (Tc) (identical thermal rating)
Operating Temperature: -55°C to 175°C (identical temperature range)

Mechanical Equivalence Requirements:

Package Type: TO-263 (D2PAK) (identical physical form factor)
Mounting Type: Surface Mount (identical assembly method)

All substitute parts listed maintain complete parametric equivalence to the main part number across all specified electrical and mechanical parameters. Packaging format differences (Tape & Reel versus bulk) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Substitute: IRLZ14STRLPBF

The IRLZ14STRLPBF is the manufacturer-recommended substitute for the obsolete IRLZ14STRR. This part maintains complete electrical and mechanical equivalence across all specified parameters. The IRLZ14STRLPBF carries active product status, ensuring long-term availability and supply chain continuity. This part is RoHS3 compliant, meeting current environmental and regulatory requirements. Inventory availability is 2400 pieces in new original condition.

Secondary Substitute: IRLZ14STRRPBF

The IRLZ14STRRPBF provides parametric equivalence identical to the primary substitute. This part is also active product status and RoHS3 compliant. Inventory availability is 876 pieces in new original condition. Selection between IRLZ14STRLPBF and IRLZ14STRRPBF is determined by packaging format requirements and supply chain logistics, as both parts are electrically and mechanically identical.

Compliance Considerations

Both substitute parts are RoHS3 compliant, whereas the original IRLZ14STRR is RoHS non-compliant. This compliance upgrade is beneficial for applications subject to environmental regulations. Both substitutes maintain REACH unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can IRLZ14STRLPBF and IRLZ14STRRPBF be used interchangeably with IRLZ14STRR?

A: Yes. Both substitute parts maintain identical electrical parameters (Vdss, Id, Rds On, Vgs(th), Qg, Ciss, power dissipation, and operating temperature range) and identical mechanical specifications (TO-263 D2PAK package, surface mount configuration). The parts are pin-compatible and functionally equivalent.

Q: What is the difference between IRLZ14STRLPBF and IRLZ14STRRPBF?

A: The electrical and mechanical specifications are identical between these two parts. The primary difference is packaging format: IRLZ14STRLPBF and IRLZ14STRRPBF are both supplied in Tape & Reel format. Inventory levels differ (2400 pieces versus 876 pieces respectively). Selection is based on supply availability and procurement requirements.

Q: Why is the original IRLZ14STRR listed as obsolete?

A: The IRLZ14STRR has reached end-of-life status. Vishay Siliconix continues to manufacture equivalent parts under the IRLZ14STRLPBF and IRLZ14STRRPBF designations, which incorporate current manufacturing standards and compliance certifications.

Q: Are there any thermal or electrical performance differences between the main part and substitutes?

A: No. All three parts (IRLZ14STRR, IRLZ14STRLPBF, IRLZ14STRRPBF) maintain identical thermal ratings (3.7W at Ta, 43W at Tc) and electrical performance across the full operating temperature range (-55°C to 175°C junction temperature).

Q: Is the TO-263 (D2PAK) package identical across all three parts?

A: Yes. All three parts use the TO-263-3 D2PAK package configuration with 2 leads plus tab. PCB footprints and thermal interface requirements are identical.

Q: What is the significance of RoHS3 compliance on the substitute parts?

A: RoHS3 compliance indicates that the substitute parts meet current environmental regulations restricting hazardous substances. The original IRLZ14STRR is RoHS non-compliant. For applications subject to environmental regulations or customer requirements, the RoHS3-compliant substitutes (IRLZ14STRLPBF and IRLZ14STRRPBF) are required.

Q: Can I mix inventory of IRLZ14STRR with IRLZ14STRLPBF or IRLZ14STRRPBF in production?

A: Yes. All three parts are electrically and mechanically equivalent. Mixed inventory can be used interchangeably in the same circuit design without modification to PCB layout, schematic, or thermal management design.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.
