Substitute Part Grouping Explanation

Substitute parts for the DFLZ9V1-TP are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

Zener voltage (Nom): 9.1 V
Tolerance: ±5%
Maximum power rating: 1 W
Maximum impedance: 4 Ohms
Operating temperature range: -55°C to 150°C

Mechanical Parameters (Critical for Substitution):

Package type: SOD-123F
Mounting type: Surface Mount
Packaging format: Tape & Reel (TR)

Compliance Parameters:

RoHS3 compliance
REACH unaffected status
ECCN: EAR99

The substitute parts PZ1AL9V1B_R1_00001 and PZ1AL9V1B-AU_R1_000A1 from Panjit International Inc. meet all critical electrical and mechanical parameters. Both parts are manufactured by the same supplier and share identical zener voltage, power rating, impedance, temperature range, and package specifications. The reverse leakage current specification for substitute parts (10 µA @ 5 V) is within acceptable operational limits compared to the main part (5 µA @ 5 V).

Engineering Selection Recommendations

Both substitute parts PZ1AL9V1B_R1_00001 and PZ1AL9V1B-AU_R1_000A1 are direct functional equivalents to the DFLZ9V1-TP. Selection between these options is based on application requirements:

PZ1AL9V1B_R1_00001 is suitable for general industrial and commercial applications requiring standard zener diode performance within the specified electrical and thermal parameters.

PZ1AL9V1B-AU_R1_000A1 carries AEC-Q101 automotive qualification and is designated for automotive-grade applications. This variant includes automotive-specific testing and reliability requirements and should be selected when automotive compliance is mandated.

All three parts maintain identical electrical performance within the specified tolerance bands, identical package geometry for PCB layout compatibility, and equivalent compliance certifications. Selection should be based on application classification (automotive versus non-automotive) and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can PZ1AL9V1B_R1_00001 and PZ1AL9V1B-AU_R1_000A1 be used interchangeably with DFLZ9V1-TP?

A: Yes, both Panjit parts are direct functional equivalents. They share identical zener voltage (9.1 V), power rating (1 W), impedance (4 Ohms), temperature range (-55°C to 150°C), and SOD-123F package specifications. The primary distinction is automotive qualification on the -AU variant.

Q: What is the difference between PZ1AL9V1B_R1_00001 and PZ1AL9V1B-AU_R1_000A1?

A: Both parts are electrically and mechanically identical. The PZ1AL9V1B-AU_R1_000A1 variant includes AEC-Q101 automotive qualification, making it suitable for automotive applications. The standard PZ1AL9V1B_R1_00001 is appropriate for non-automotive applications.

Q: Are there any reverse leakage current differences between the main part and substitutes?

A: The DFLZ9V1-TP specifies 5 µA reverse leakage at 5 V, while both Panjit substitutes specify 10 µA at 5 V. Both values remain within acceptable operational limits for zener diode applications and do not affect functional interchangeability.

Q: Is the SOD-123FL package compatible with SOD-123F footprints?

A: Yes. The SOD-123FL designation refers to the supplier device package format (Tape & Reel), while SOD-123F is the standard package case designation. Both refer to the same physical package geometry and are footprint-compatible.

Q: Are all three parts RoHS3 compliant?

A: Yes. DFLZ9V1-TP, PZ1AL9V1B_R1_00001, and PZ1AL9V1B-AU_R1_000A1 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
