Substitute Part Grouping Explanation

Substitute parts for the BZX79-C2V7,113 are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: 2.7 V nominal zener voltage, 400 mW maximum power, 100 Ohms maximum impedance, 20 µA reverse leakage current, and through-hole DO-35 axial mounting. These parts differ only in tolerance grade (±2% versus ±5%) or packaging format (bulk versus cut tape). Parametric equivalents include BZX79-B2V7,113, BZX79-B2V7,133, BZX79-B2V7,143, BZX79-C2V7,133, and BZX79-C2V7,143.

Similar Parts share the same nominal zener voltage (2.7 V) and package type (DO-35 axial) but differ in one or more electrical parameters. These include BZX79C2V7 (Taiwan Semiconductor Corporation, 500 mW power rating, 75 µA reverse leakage) and BZX79C2V7-T50A (Fairchild Semiconductor, 500 mW power rating, 75 µA reverse leakage). Similar parts are suitable only when application requirements permit higher power dissipation and reverse leakage specifications.

Engineering Selection Recommendations

Parametric Equivalent Selection (BZX79-B2V7 Series and BZX79-C2V7 Variants)

Parts BZX79-B2V7,113, BZX79-B2V7,133, BZX79-B2V7,143, BZX79-C2V7,133, and BZX79-C2V7,143 are direct parametric equivalents suitable for one-to-one replacement with the BZX79-C2V7,113. All maintain identical electrical performance across zener voltage, power dissipation, impedance, reverse leakage, and forward voltage specifications. All substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the primary part.

The BZX79-B2V7 series offers tighter tolerance (±2%) compared to the ±5% tolerance of the BZX79-C2V7,113, providing enhanced voltage regulation accuracy where circuit design permits. Selection between cut tape and bulk packaging depends on assembly process requirements and inventory management practices.

Similar Part Selection (BZX79C2V7 and BZX79C2V7-T50A)

Parts BZX79C2V7 and BZX79C2V7-T50A are classified as similar parts due to elevated power dissipation (500 mW versus 400 mW) and increased reverse leakage current (75 µA versus 20 µA). These parts are suitable only when circuit design specifications accommodate higher power handling and leakage characteristics. The BZX79C2V7-T50A maintains the full operating temperature range (-65 to 200°C) of the primary part, while BZX79C2V7 is rated to 175°C maximum junction temperature.

All substitute and similar parts maintain active product status and appropriate regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B2V7,113 replace BZX79-C2V7,113 in all applications?

A: Yes. The BZX79-B2V7,113 is a parametric equivalent with identical electrical specifications across all critical parameters: 2.7 V nominal zener voltage, 400 mW power dissipation, 100 Ohms impedance, 20 µA reverse leakage, and -65 to 200°C operating temperature range. The tighter ±2% tolerance of the BZX79-B2V7,113 provides superior voltage regulation accuracy compared to the ±5% tolerance of the BZX79-C2V7,113.

Q: What is the difference between BZX79-C2V7,113 and BZX79-C2V7,133?

A: Both parts are parametric equivalents with identical electrical specifications. The difference lies in packaging format: BZX79-C2V7,113 is supplied in cut tape (CT) packaging with 1488 pieces in stock, while BZX79-C2V7,133 is also supplied in cut tape with 3422 pieces in stock. Both are manufactured by Nexperia USA Inc. and carry ROHS3 compliance.

Q: Can BZX79C2V7 (Taiwan Semiconductor Corporation) be used as a direct replacement?

A: BZX79C2V7 is classified as a similar part, not a parametric equivalent. While it maintains the same 2.7 V nominal zener voltage and DO-35 axial package, it differs in power dissipation (500 mW versus 400 mW), reverse leakage current (75 µA versus 20 µA), and maximum operating temperature (175°C versus 200°C). Use this part only when circuit design specifications permit higher power handling and leakage characteristics.

Q: What is the significance of the tolerance difference between ±2% and ±5%?

A: Tolerance specifies the allowable deviation of the zener voltage from its nominal 2.7 V rating. The ±2% tolerance of BZX79-B2V7 series parts restricts zener voltage to 2.646 to 2.754 V, while the ±5% tolerance of BZX79-C2V7 series parts allows 2.565 to 2.835 V. Applications requiring tighter voltage regulation should specify the ±2% tolerance variant.

Q: Are all substitute parts ROHS3 compliant?

A: All parametric equivalent parts (BZX79-B2V7 and BZX79-C2V7 variants) are ROHS3 compliant. The similar part BZX79C2V7-T50A (Fairchild Semiconductor) does not carry RoHS status designation in the provided specifications. Verify RoHS compliance requirements with your procurement or quality assurance department before final part selection.

Q: What packaging options are available for the BZX79-C2V7,113?

A: The BZX79-C2V7,113 is supplied in cut tape (CT) packaging. Parametric equivalents offer alternative packaging: BZX79-B2V7,113 and BZX79-B2V7,143 are supplied in bulk packaging, while BZX79-B2V7,133 is supplied in cut tape. Similar parts BZX79C2V7 is supplied in tape & reel (TR) format, and BZX79C2V7-T50A is supplied in bulk packaging. Select packaging based on assembly process requirements and minimum order quantities.

Q: Can I use BZX79-B2V7,143 if BZX79-C2V7,113 is unavailable?

A: Yes. The BZX79-B2V7,143 is a parametric equivalent with identical electrical specifications and superior ±2% tolerance. The only difference is packaging format (bulk versus cut tape). With 80,972 pieces in stock, BZX79-B2V7,143 offers high availability for immediate procurement.
