MAZD06200L Equivalent & Substitute Parts

Part Overview

The MAZD06200L is a 6.2 V Zener diode manufactured by Panasonic Electronic Components, rated for 120 mW maximum power dissipation in a surface mount SSSMini2-F2 package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. Substitute parts must maintain electrical compatibility across voltage regulation, power handling, and thermal characteristics while accommodating available packaging and supplier options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZD06200L is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage nominal value: 6.2 V (primary functional requirement)
• Maximum power dissipation: 120 mW or greater (thermal capability)
• Impedance characteristics: 30 Ohms maximum (dynamic response)
• Reverse leakage current: 200 nA @ 4 V (leakage performance)
• Forward voltage: 1 V @ 10 mA (conduction characteristics)

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount (assembly process compatibility)
• Package configuration: 2-SMD, Flat Lead (PCB footprint compatibility)
• Moisture sensitivity: MSL 1 (Unlimited) (storage and handling requirements)

The identified substitute parts CDZT2R6.2B and CDZT2RA6.2B maintain the 6.2 V zener voltage specification and surface mount 2-SMD flat lead package configuration. Both substitute parts are manufactured by Rohm Semiconductor and operate within the specified electrical parameter ranges for zener diode applications requiring 6.2 V regulation.

Parameter Comparison

Engineering Selection Recommendations

CDZT2RA6.2B (Primary Substitute): CDZT2RA6.2B is the recommended substitute for new designs and production continuity. This part maintains active product status with Rohm Semiconductor, ensuring long-term availability and supply chain stability. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Operating temperature range of -55°C to 150°C provides thermal coverage for industrial and commercial applications. The ±2% tolerance specification offers improved voltage regulation accuracy compared to the original MAZD06200L.

CDZT2R6.2B (Secondary Substitute): CDZT2R6.2B is functionally equivalent to CDZT2RA6.2B but carries a "Not For New Designs" product status. This part remains suitable for legacy system maintenance and replacement applications where existing inventory is available. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Selection of this part should be limited to applications where design revision is not feasible.

Electrical Trade-offs: Both substitute parts operate at reduced maximum power dissipation (100 mW versus 120 mW). Applications requiring thermal headroom near the 120 mW limit require thermal analysis to confirm adequate margin at 100 mW operation. Impedance increases from 30 Ohms to 60 Ohms; this affects dynamic response characteristics in high-frequency regulation circuits. Reverse leakage current increases from 200 nA to 1 µA, which may impact precision analog circuits with high-impedance nodes.

Frequently Asked Questions (FAQ)

Q: Can CDZT2RA6.2B directly replace MAZD06200L without PCB modification?

A: Both parts use 2-SMD flat lead packages (SSSMini2-F2 and VMN2 respectively). Physical footprint compatibility requires verification of specific pad dimensions and spacing for the VMN2 package against the original SSSMini2-F2 layout. Consult package datasheets for precise dimensional comparison before confirming drop-in compatibility.

Q: What is the impact of reduced power rating (100 mW vs. 120 mW)?

A: The 20 mW reduction in maximum power dissipation requires thermal margin analysis for applications operating near the original 120 mW specification. Verify that circuit operating conditions maintain power dissipation below 100 mW under worst-case conditions including temperature extremes and component tolerance stack-up.

Q: How does the impedance increase from 30 Ohms to 60 Ohms affect circuit performance?

A: Higher impedance reduces the zener diode's ability to regulate voltage under transient load changes. Applications with fast load transients or high-frequency noise rejection may experience degraded performance. Circuits with slow load changes or integrated filtering typically show negligible impact.

Q: Are there compliance differences between the original and substitute parts?

A: CDZT2RA6.2B and CDZT2R6.2B are ROHS3 compliant and REACH unaffected. The original MAZD06200L compliance status is not specified in available documentation. Confirm compliance requirements for your specific application and regulatory jurisdiction.

Q: Why is CDZT2RA6.2B preferred over CDZT2R6.2B?

A: CDZT2RA6.2B carries active product status, ensuring continued availability and manufacturing support. CDZT2R6.2B is designated "Not For New Designs," indicating potential future discontinuation. For new designs and long-term production, CDZT2RA6.2B provides supply chain security.

Q: What is the significance of ±2% tolerance versus ±6% tolerance?

A: The substitute parts offer tighter voltage tolerance (±2% versus ±6%), resulting in more precise zener voltage regulation. This improvement reduces voltage variation across the component population and may eliminate the need for post-regulation filtering in precision applications.
