Substitute Part Grouping Explanation

Substitute parts for the DZ2S10000L are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Zener (Nom): 10 V (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: SC-79, SOD-523 (exact match required)
• Power - Max: 150 mW or greater (equal or higher rating acceptable)
• Impedance (Max): 30 Ohms or lower (equal or lower impedance acceptable)
• RoHS Compliance: Required

Secondary Compatibility Factors:

• Tolerance: ±5% or tighter (tighter tolerance acceptable)
• Current - Reverse Leakage @ Vr: 50 nA or lower (lower leakage acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

All identified substitute parts meet the primary substitution criteria. Variations in power dissipation capability, impedance characteristics, and tolerance specifications are documented in the parameter comparison table below.

Engineering Selection Recommendations

BZT585B10T-7 (Diodes Incorporated)

This substitute provides enhanced power dissipation capability at 350 mW, exceeding the original 150 mW specification. The part features improved impedance characteristics at 10 Ohms maximum and tighter voltage tolerance at ±2%. Product status is Active with full availability. ROHS3 compliance and REACH Unaffected status provide regulatory alignment. Higher reverse leakage current (200 nA @ 7 V) should be evaluated against circuit requirements.

EDZVFHT2R10B (Rohm Semiconductor)

This substitute maintains identical power rating (150 mW) and impedance (30 Ohms) to the original part. Voltage tolerance is tighter at ±2.2%. The part carries AEC-Q101 automotive qualification and Automotive grade designation, suitable for applications requiring automotive-level reliability. Operating temperature maximum of 150°C (TJ) is specified. ROHS3 compliance and REACH Unaffected status are confirmed. Product status is Active.

EDZVT2R10B (Rohm Semiconductor)

This substitute provides the closest electrical match to the original DZ2S10000L, with identical power rating (150 mW) and impedance (30 Ohms). Operating temperature range is -55°C to 150°C. Voltage tolerance specification is not provided in available data. Highest inventory availability (132,487 Pcs) among all substitutes. ROHS3 compliance and REACH Unaffected status are confirmed. Product status is Active with EDZV series designation.

Frequently Asked Questions (FAQ)

Q: Can BZT585B10T-7 be used as a direct replacement for DZ2S10000L?

A: Yes. Both parts share identical 10 V zener voltage, surface mount configuration, and SC-79/SOD-523 package specifications. The BZT585B10T-7 provides higher power dissipation (350 mW vs. 150 mW) and lower impedance (10 Ohms vs. 30 Ohms), making it suitable for applications where the original part is specified. Reverse leakage current is higher at 200 nA versus 50 nA; circuit design must accommodate this difference.

Q: What is the difference between EDZVFHT2R10B and EDZVT2R10B?

A: Both parts are manufactured by Rohm Semiconductor with identical electrical specifications: 10 V zener voltage, 150 mW power rating, and 30 Ohms impedance. EDZVFHT2R10B carries AEC-Q101 automotive qualification and specifies maximum operating temperature of 150°C (TJ). EDZVT2R10B provides wider operating temperature range (-55°C to 150°C) and significantly higher inventory availability. Selection depends on automotive qualification requirements and temperature operating range needs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS3 compliance certification. The original DZ2S10000L is RoHS Compliant. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the significance of the ±2% and ±2.2% tolerance specifications on substitute parts?

A: Tighter tolerance specifications (±2% and ±2.2%) compared to the original ±5% tolerance indicate improved voltage regulation accuracy. These substitutes maintain zener voltage within narrower bands, which may benefit circuit performance in precision voltage reference applications. Circuit design must confirm whether tighter tolerance provides functional advantage or is simply an improved specification.

Q: Can these parts be used interchangeably in the same PCB layout?

A: Yes. All substitute parts use identical SC-79/SOD-523 package specifications and surface mount configuration, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the DZ2S10000L.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without special moisture control measures and does not require baking before reflow soldering. All substitute parts carry identical MSL 1 (Unlimited) rating.

Q: Which substitute part should be selected for new designs?

A: Selection depends on specific application requirements. For standard 10 V zener applications with 150 mW power requirements, EDZVT2R10B offers highest availability and wide operating temperature range. For automotive applications, EDZVFHT2R10B provides AEC-Q101 qualification. For applications requiring higher power dissipation or lower impedance, BZT585B10T-7 is appropriate.
