DZ2J200M0L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2J200M0L is a 20 V, 200 mW surface mount zener diode manufactured by Panasonic Electronic Components in the SC-90/SOD-323F package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. The part operates as a voltage regulation and transient protection element in electronic circuits. Substitute parts must maintain electrical equivalence across voltage rating, power dissipation, and package form factor to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J200M0L is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Voltage - Zener (Nom): 20 V (exact match required)
• Power - Max: 200 mW (exact match required)
• Package / Case: SC-90, SOD-323F (mechanical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)

Secondary Compatibility Parameters:

• Tolerance: ±2.5% or tighter (±2%, ±2.18%, ±5% acceptable within circuit design margins)
• Impedance (Max): 80 Ohms or lower (lower impedance acceptable)
• Current - Reverse Leakage @ Vr: 50 nA or lower (lower leakage acceptable)
• RoHS Compliance: Required for environmental and regulatory compatibility

All identified substitute parts meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): UDZSTE-1720B (Rohm Semiconductor) is the preferred substitute. This part maintains exact electrical specifications (20 V, 200 mW), achieves tighter tolerance (±2%), and is classified as active with ROHS3 compliance. Operating temperature range of -55°C to 150°C provides extended thermal performance. High inventory availability (64,795 pcs) ensures supply continuity.

Secondary Substitute (Automotive Applications): UDZVFHTE-1720B (Rohm Semiconductor) is specified for automotive-grade applications with AEC-Q101 qualification. Tolerance of ±2.18% and identical electrical ratings make this suitable for automotive circuit protection. Maximum junction temperature of 150°C supports demanding thermal environments.

Alternative Substitute (Cost Optimization): BZT52-C20S_R1_00001 (Panjit International Inc.) provides functional equivalence with relaxed tolerance (±5%) and lower impedance (50 Ohms). This part is suitable for applications where tighter voltage regulation is not critical. Active product status and ROHS3 compliance ensure regulatory compliance.

Tertiary Substitute (General Purpose): UDZVTE-1720B (Rohm Semiconductor) offers equivalent electrical performance with unspecified tolerance and identical impedance (85 Ohms). Active status and extensive inventory (52,400 pcs) support high-volume applications.

All substitute parts are surface mount compatible with SC-90/SOD-323F packaging and require no PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can BZT52-C20S_R1_00001 replace DZ2J200M0L directly on the PCB? A: Yes. Both parts share identical package designation (SC-90, SOD-323F), mounting type (surface mount), and electrical ratings (20 V, 200 mW). The ±5% tolerance of the Panjit part is within acceptable substitution parameters for zener diode applications.

Q: What is the difference between UDZSTE-1720B and UDZVFHTE-1720B? A: UDZVFHTE-1720B is automotive-grade with AEC-Q101 qualification and maximum junction temperature of 150°C. UDZSTE-1720B is general-purpose with operating temperature range of -55°C to 150°C. Both maintain identical electrical specifications (20 V, 200 mW, ±2% tolerance).

Q: Does tolerance variation affect circuit performance? A: Tolerance differences (±2%, ±2.18%, ±2.5%, ±5%) represent acceptable variations in zener voltage regulation. Selection depends on circuit design margins. Tighter tolerance parts (±2%) provide more precise voltage regulation; relaxed tolerance parts (±5%) are suitable for general protection applications.

Q: Are all substitute parts RoHS compliant? A: Yes. All identified substitutes carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original DZ2J200M0L RoHS Compliant status.

Q: What is the significance of impedance differences? A: Impedance values (50 Ohms to 85 Ohms) affect transient response characteristics. Lower impedance (BZT52-C20S_R1_00001 at 50 Ohms) provides faster response to voltage transients. Higher impedance values remain within acceptable substitution parameters for standard protection applications.

Q: Can UDZVTE-1720B be used if tolerance is not specified? A: Yes. Unspecified tolerance in UDZVTE-1720B indicates manufacturer standard tolerance, which is acceptable for general-purpose zener diode applications. Confirm tolerance requirements with circuit design specifications before selection.

Q: Is inventory availability a factor in part selection? A: Inventory levels (ranging from 3,375 to 64,795 pcs) indicate supply continuity. UDZSTE-1720B and UDZVTE-1720B offer highest availability for high-volume production requirements.
