Substitute Part Grouping Explanation

Substitute parts for the BZX79-B10,113 are qualified based on identical electrical performance parameters and compatible mechanical form factors. The substitution criteria are strictly limited to the following parameters:

Voltage - Zener (Nom): 10 V
Tolerance: ±2%
Power - Max: 400 mW
Impedance (Max): 20 Ohms
Current - Reverse Leakage @ Vr: 200 nA @ 7 V
Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
Operating Temperature Range: -65°C to 200°C
Mounting Type: Through Hole
Package / Case: DO-204AH, DO-35, Axial

All identified substitute parts maintain these electrical and mechanical specifications. Variations in packaging configuration (Cut Tape versus Bulk) and supplier device package designation do not affect functional equivalence.

Engineering Selection Recommendations

All three parts—BZX79-B10,113, BZX79-B10,133, and BZX79-B10,143—are functionally equivalent for applications requiring a 10 V, 400 mW Zener diode with ±2% tolerance and through-hole axial mounting. Selection between these parts is determined by supply chain availability, packaging requirements, and compliance certifications.

BZX79-B10,113 and BZX79-B10,133 are both supplied by Nexperia USA Inc. in Cut Tape packaging with confirmed ROHS3 compliance. BZX79-B10,143 is supplied by NXP USA Inc. in Bulk packaging. All parts maintain identical electrical performance across the specified operating temperature range of -65°C to 200°C.

For applications requiring documented ROHS3 compliance, BZX79-B10,113 and BZX79-B10,133 are directly interchangeable. BZX79-B10,143 is suitable for high-volume applications where bulk packaging is preferred, provided compliance documentation is verified through the supplier.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B10,133 be used as a direct replacement for BZX79-B10,113?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and maintain identical electrical specifications including 10 V nominal Zener voltage, 400 mW power rating, ±2% tolerance, and through-hole axial packaging. The parts are functionally equivalent.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape packaging (BZX79-B10,113 and BZX79-B10,133) is supplied on individual tape segments suitable for automated pick-and-place assembly. Bulk packaging (BZX79-B10,143) is supplied in loose form, typically for manual assembly or high-volume reel applications. Electrical performance is identical.

Q: Are all three parts ROHS3 compliant?

A: BZX79-B10,113 and BZX79-B10,133 are confirmed ROHS3 compliant. ROHS3 compliance status for BZX79-B10,143 is not specified in the provided documentation.

Q: Can BZX79-B10,143 be substituted for BZX79-B10,113 in a circuit design?

A: Yes, from an electrical standpoint. Both parts maintain identical Zener voltage, power rating, impedance, and temperature operating range. The manufacturer differs (NXP USA Inc. versus Nexperia USA Inc.), and packaging is Bulk rather than Cut Tape. Verify compliance requirements and supplier documentation for your specific application.

Q: What parameters must remain constant for substitution?

A: The following parameters must be identical: Voltage - Zener (Nom) at 10 V, Tolerance at ±2%, Power - Max at 400 mW, Impedance (Max) at 20 Ohms, Current - Reverse Leakage @ Vr at 200 nA @ 7 V, Voltage - Forward (Vf) (Max) @ If at 900 mV @ 10 mA, Operating Temperature Range from -65°C to 200°C, Mounting Type as Through Hole, and Package / Case as DO-204AH, DO-35, Axial.

Q: Is there a difference in performance between Nexperia USA Inc. and NXP USA Inc. variants?

A: No performance difference exists based on the provided electrical specifications. Both manufacturers supply parts meeting identical electrical parameters. Verify supplier documentation and lead times for your procurement requirements.
