BZV55C6V2-TP Equivalent & Substitute Parts

Part Overview

The BZV55C6V2-TP is a 6.2 V Zener diode rated at 500 mW, manufactured by Micro Commercial Co in a Mini MELF surface mount package. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing design requirements and production continuity. Substitute parts must maintain the core electrical specifications: 6.2 V nominal Zener voltage, ±5% to ±6% tolerance, and compatible surface mount packaging with equivalent or superior power ratings.

Substitute Part Grouping Explanation

Substitution of the BZV55C6V2-TP is determined by the following critical parameters:

Primary Matching Criteria:

Zener voltage: 6.2 V nominal
Tolerance: ±5% to ±6%
Impedance (Max): 10 Ohms
Mounting type: Surface Mount
RoHS3 compliance

Secondary Compatibility Factors:

Power rating: Equal to or greater than 500 mW
Operating temperature range: Minimum -55°C to 150°C coverage
Package compatibility: DO-213AC, MINI-MELF, SOD-80, or equivalent surface mount packages

Substitute parts are grouped into two categories: direct equivalents maintaining identical power ratings and package form factors, and functional alternatives with reduced power ratings but compatible electrical characteristics for lower-power applications.

Engineering Selection Recommendations

Preferred Substitutes (Direct Equivalents):

BZV55-C6V2,115 and BZV55-C6V2,135 (Nexperia USA Inc.) are the primary recommended substitutes. Both parts maintain 6.2 V nominal Zener voltage, 500 mW power rating, 10 Ohms maximum impedance, and compatible MINI-MELF packaging. These parts feature improved tolerance (±5% versus ±6%), extended operating temperature range (-65°C to 200°C), and active product status with ROHS3 compliance. The extended temperature range provides superior performance margin over the original part's -55°C to 150°C specification.

Secondary Alternative:

BZT52C6V2-TP (Micro Commercial Co) maintains electrical compatibility with 6.2 V nominal voltage, ±6% tolerance, and 10 Ohms impedance. However, this part features reduced power rating (200 mW versus 500 mW) and different package form (SOD-123 versus MINI-MELF). This substitute is suitable only for applications where power dissipation does not exceed 200 mW and PCB layout accommodates SOD-123 package dimensions.

Not Recommended:

BZV55C6V2 (Microchip Technology) is not recommended due to RoHS non-compliance status, which conflicts with the original part's ROHS3 compliance requirement. Additionally, power rating specification is not provided for this variant.

Frequently Asked Questions (FAQ)

Q: Can BZV55-C6V2,115 or BZV55-C6V2,135 be used as direct replacements for BZV55C6V2-TP?

A: Yes. Both Nexperia parts maintain identical Zener voltage (6.2 V), impedance (10 Ohms), and power rating (500 mW). Package compatibility is confirmed through DO-213AC, MINI-MELF, SOD-80 designation. The improved tolerance (±5%) and extended temperature range provide enhanced performance characteristics.

Q: What is the difference between BZV55-C6V2,115 and BZV55-C6V2,135?

A: Both parts are electrically and mechanically identical. The numerical suffixes (115 and 135) represent different packaging tape configurations or manufacturing batches from Nexperia. Selection between these variants depends on packaging and inventory availability requirements.

Q: Is BZT52C6V2-TP suitable for all applications using BZV55C6V2-TP?

A: No. BZT52C6V2-TP has reduced power rating (200 mW versus 500 mW) and different package form (SOD-123 versus MINI-MELF). This substitute is compatible only with applications where maximum power dissipation does not exceed 200 mW and PCB layout supports SOD-123 package dimensions.

Q: Why is the Microchip BZV55C6V2 not recommended?

A: The Microchip variant is RoHS non-compliant, conflicting with the original part's ROHS3 compliance status. Additionally, power rating is not specified for this component, preventing confirmation of 500 mW capability.

Q: Are there package compatibility concerns when substituting with Nexperia parts?

A: No. BZV55-C6V2,115 and BZV55-C6V2,135 use identical package designation (DO-213AC, MINI-MELF, SOD-80) as the original BZV55C6V2-TP, ensuring direct PCB footprint compatibility.

Q: What compliance certifications should be verified for substitute parts?

A: All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory requirements. ECCN classification (EAR99) and HTSUS code (8541.10.0050) remain consistent across all equivalent parts.
