Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAZS0510ML are selected based on the following critical electrical parameters:

Primary Matching Criteria:

• Zener voltage nominal rating of 5.1 V or equivalent (5.09 V acceptable within tolerance)
• Surface mount technology compatibility
• Moisture sensitivity level 1 (unlimited)

Secondary Compatibility Factors:

• Power dissipation rating equal to or greater than 150 mW
• Impedance maximum rating of 60 Ohms or lower
• Reverse leakage current specifications
• Forward voltage characteristics

The substitute parts are grouped into two categories based on package compatibility and power rating:

Group 1 - Direct Package Compatibility (SC-79/SOD-523): EDZVFHT2R5.1B maintains the original package footprint and 150 mW power rating, providing direct mechanical and electrical substitution.

Group 2 - Enhanced Power Rating (Alternative Packages): BZT52H-C5V1,115 and BZX84J-C5V1,115 offer higher power dissipation ratings (375 mW and 550 mW respectively) in alternative surface mount packages, suitable for applications requiring increased thermal headroom.

Parameter Comparison

Engineering Selection Recommendations

EDZVFHT2R5.1B (Rohm Semiconductor) is the primary substitute for direct replacement applications. This part maintains identical package geometry (SC-79, SOD-523), matching power rating (150 mW), and provides superior voltage tolerance (±2.16% versus ±3%). The component carries AEC-Q101 automotive qualification and ROHS3 compliance, ensuring regulatory alignment with modern manufacturing standards.

BZT52H-C5V1,115 (Nexperia USA Inc.) serves applications requiring increased power dissipation capability. With 375 mW maximum power rating and SOD-123F packaging, this part accommodates thermal requirements exceeding the original specification while maintaining 5.1 V nominal voltage and 60 Ohms maximum impedance. AEC-Q101 qualification and ROHS3 compliance are provided.

BZX84J-C5V1,115 (Nexperia USA Inc.) addresses high-power applications with 550 mW maximum dissipation in SOD-323F packaging. This substitute offers the highest thermal capacity among available options while preserving electrical characteristics. AEC-Q101 qualification and ROHS3 compliance are included.

All substitute parts are currently in active production status with substantial inventory availability, eliminating obsolescence risk associated with the original MAZS0510ML component.

Frequently Asked Questions (FAQ)

Q: Can EDZVFHT2R5.1B be used as a direct replacement for MAZS0510ML?

A: Yes. EDZVFHT2R5.1B maintains the same package footprint (SC-79, SOD-523), identical power rating (150 mW), and equivalent zener voltage (5.09 V within tolerance). No PCB layout modifications are required.

Q: What is the primary difference between the three substitute options?

A: The three substitutes differ in power dissipation rating and package size. EDZVFHT2R5.1B matches the original 150 mW rating in the same package. BZT52H-C5V1,115 provides 375 mW in SOD-123F packaging. BZX84J-C5V1,115 offers 550 mW in SOD-323F packaging. Selection depends on thermal requirements and available PCB space.

Q: Are package changes required when using BZT52H-C5V1,115 or BZX84J-C5V1,115?

A: Yes. Both parts use different surface mount packages than the original MAZS0510ML. BZT52H-C5V1,115 uses SOD-123F and BZX84J-C5V1,115 uses SOD-323F. PCB footprint modifications are necessary for these substitutes.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All three substitute parts carry AEC-Q101 qualification and automotive grade designation, meeting automotive industry standards.

Q: What is the tolerance difference between MAZS0510ML and the substitutes?

A: MAZS0510ML specifies ±3% tolerance. BZT52H-C5V1,115 and BZX84J-C5V1,115 specify ±5% tolerance. EDZVFHT2R5.1B provides superior ±2.16% tolerance, offering tighter voltage regulation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant, meeting environmental and regulatory requirements for modern electronics manufacturing.

Q: What is the impedance specification for EDZVFHT2R5.1B?

A: EDZVFHT2R5.1B specifies 80 Ohms maximum impedance, compared to 60 Ohms for the original part. This represents a 33% increase in impedance and should be evaluated for applications with strict impedance requirements.

Q: Which substitute offers the best inventory availability?

A: BZX84J-C5V1,115 has the highest inventory level at 24,744 pieces. BZT52H-C5V1,115 has 10,023 pieces available. EDZVFHT2R5.1B has 21,329 pieces available. All three parts maintain substantial stock levels.
