Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2W05100L is determined by the following critical parameters:

Primary Substitution Criteria:

• Zener voltage rating within acceptable circuit tolerance
• Power dissipation capacity of 1 W
• Reverse leakage current specification of 20 µA @ 1 V
• Surface mount package type (SOD-123F)
• Moisture sensitivity level MSL 1 (Unlimited)

Secondary Compatibility Factors:

• RoHS compliance status
• Operating temperature range capability
• Forward voltage characteristics

The three substitute parts identified (KDZVTR4.7B, KDZVTR5.1B, and KDZVTFTR5.1B) from Rohm Semiconductor meet the core electrical and mechanical requirements. These parts are manufactured by an established semiconductor supplier with active product status and current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

KDZVTR5.1B is the primary substitute for DZ2W05100L. This part maintains the closest nominal Zener voltage specification at 5.4 V, matching the 1 W power rating and SOD-123F package. The part is currently in active production status with 24,915 pieces in stock inventory. ROHS3 compliance exceeds the original RoHS requirement, and the 150°C operating temperature capability provides thermal margin.

KDZVTFTR5.1B is an alternative substitute with automotive-grade qualification (AEC-Q101) and identical electrical specifications to KDZVTR5.1B. This part is suitable for applications requiring automotive-level reliability and traceability. Inventory availability is 10,249 pieces.

KDZVTR4.7B is a secondary substitute option with a nominal Zener voltage of 4.95 V. This part is appropriate only for circuit designs where the lower voltage rating is acceptable within system tolerance margins. Inventory availability is 12,236 pieces.

All three substitute parts are manufactured by Rohm Semiconductor, an established supplier with REACH compliance documentation and EAR99 export classification matching the original part.

Frequently Asked Questions (FAQ)

Q: Can KDZVTR5.1B directly replace DZ2W05100L in existing designs?

A: KDZVTR5.1B is electrically compatible as a substitute. Both parts share identical power ratings (1 W), reverse leakage current specifications (20 µA @ 1 V), and SOD-123F package geometry. The nominal Zener voltage differs by 0.3 V (5.4 V versus 5.1 V), which must be evaluated against circuit tolerance requirements.

Q: What is the voltage difference between the main part and substitute options?

A: DZ2W05100L operates at 5.1 V nominal. KDZVTR5.1B and KDZVTFTR5.1B operate at 5.4 V nominal (0.3 V higher). KDZVTR4.7B operates at 4.95 V nominal (0.15 V lower). Circuit designs must accommodate these voltage variations within system specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. DZ2W05100L is RoHS Compliant. All three substitute parts (KDZVTR4.7B, KDZVTR5.1B, KDZVTFTR5.1B) are ROHS3 Compliant, which represents an enhanced compliance standard.

Q: What is the difference between KDZVTR5.1B and KDZVTFTR5.1B?

A: Both parts share identical electrical specifications (5.4 V nominal, 1 W power, 20 µA reverse leakage). KDZVTFTR5.1B carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. KDZVTR5.1B is the standard industrial-grade equivalent.

Q: Are the substitute parts available in the same packaging format?

A: All substitute parts are supplied in Cut Tape (CT) and Digi-Reel® packaging. The original DZ2W05100L packaging format is not specified in available documentation. All parts use identical SOD-123F surface mount package geometry.

Q: What is the moisture sensitivity rating for substitute parts?

A: All substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, identical to the original DZ2W05100L specification.

Q: Do substitute parts have specified operating temperature ranges?

A: Substitute parts are rated for 150°C operating temperature. The original DZ2W05100L does not specify an operating temperature range in available documentation.
