Both parts maintain identical Zener voltage (60 V), power rating (500 mW), tolerance (±5%), impedance (170 Ohms), reverse leakage current (100 nA @ 46 V), forward voltage (1.1 V @ 200 mA), and operating temperature range (-65°C ~ 175°C). Package compatibility is confirmed with DO-213AC, MINI-MELF, SOD-80 designation. Both parts are ROHS3 Compliant and carry Active product status. TZM5264B-GS08 offers higher inventory availability (22,456 pcs) compared to TZM5264B-GS18 (683 pcs).

Direct Manufacturer Equivalents with Package Variants:

The 1N5264BUR-1 (Microchip Technology) matches all critical electrical parameters including Zener voltage, power rating, tolerance, impedance, reverse leakage, and forward voltage specifications. Operating temperature range is identical (-65°C ~ 175°C). Package variant is DO-213AA, which is mechanically compatible within the MELF family. Product status is Active with 998 pcs inventory. RoHS compliance status is non-compliant, requiring evaluation against design requirements.

The CDLL5264B (Microchip Technology) provides electrical equivalence with 60 V Zener voltage, ±5% tolerance, 170 Ohms impedance, 100 nA @ 46 V reverse leakage, and 1.1 V @ 200 mA forward voltage. Operating temperature range matches at -65°C ~ 175°C. Package variant is DO-213AB, MELF, compatible within the MELF family. Product status is Active with 833 pcs inventory. RoHS compliance status is non-compliant.

The MMSZ5264B-TP (Micro Commercial Co) maintains 60 V Zener voltage, 500 mW power rating, and ±5% tolerance. Operating temperature range is reduced to -55°C ~ 150°C, representing a narrower specification window. Package variant is SOD-123, which differs from the original Mini MELF package. Product status is Active with 827 pcs inventory. ROHS3 Compliant. This part is suitable only for applications not requiring the full -65°C lower temperature limit or the original Mini MELF package form factor.

Frequently Asked Questions (FAQ)

Q: Can the TZM5264B-GS08 or TZM5264B-GS18 be used as direct replacements for the DL5264B-TP?

A: Yes. Both Vishay parts provide complete electrical equivalence with identical Zener voltage (60 V), power rating (500 mW), tolerance (±5%), impedance (170 Ohms), reverse leakage current (100 nA @ 46 V), forward voltage (1.1 V @ 200 mA), and operating temperature range (-65°C ~ 175°C). Package designation is identical (DO-213AC, MINI-MELF, SOD-80). Both parts are ROHS3 Compliant and carry Active product status.

Q: What is the difference between TZM5264B-GS08 and TZM5264B-GS18?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format: TZM5264B-GS08 is supplied in Tape & Reel format with 22,456 pcs inventory availability, while TZM5264B-GS18 is also Tape & Reel with 683 pcs inventory availability. Selection between these variants depends on procurement volume requirements and lead time considerations.

Q: Is the MMSZ5264B-TP suitable for all applications requiring the DL5264B-TP?

A: The MMSZ5264B-TP is suitable only for applications where the operating temperature range of -55°C ~ 150°C is acceptable. The original DL5264B-TP specifies -65°C ~ 175°C. Additionally, the MMSZ5264B-TP uses SOD-123 package, which differs from the original Mini MELF package. PCB layout and thermal management characteristics may differ. Electrical parameters (60 V Zener voltage, 500 mW power, ±5% tolerance) are equivalent.

Q: What are the package compatibility considerations between DO-213AA, DO-213AB, and DO-213AC?

A: All three designations (DO-213AA, DO-213AB, DO-213AC) belong to the MELF family of Surface Mount packages and are mechanically compatible for PCB footprint purposes. DO-213AC is the original package for the DL5264B-TP (Mini MELF, SOD-80). DO-213AA and DO-213AB represent alternative MELF variants. Physical dimensions and lead configurations differ slightly; PCB layout verification is required when substituting between these package variants.

Q: Are there RoHS compliance differences between substitute options?

A: Yes. The TZM5264B-GS08 and TZM5264B-GS18 (Vishay) and MMSZ5264B-TP (Micro Commercial Co) are ROHS3 Compliant. The 1N5264BUR-1 and CDLL5264B (Microchip Technology) are RoHS non-compliant. Design requirements and regulatory obligations determine which compliance status is acceptable.

Q: Can the 1N5264BUR-1 or CDLL5264B be used if RoHS compliance is not required?

A: Yes. Both Microchip parts provide complete electrical equivalence with the DL5264B-TP: 60 V Zener voltage, 500 mW power rating, ±5% tolerance, 170 Ohms impedance, 100 nA @ 46 V reverse leakage, 1.1 V @ 200 mA forward voltage, and -65°C ~ 175°C operating temperature range. Package variants (DO-213AA and DO-213AB respectively) are MELF-family compatible. Product status is Active for both parts. RoHS non-compliance must be evaluated against design and regulatory requirements.

Q: What inventory considerations should guide part selection?

A: TZM5264B-GS08 offers the highest inventory availability at 22,456 pcs, providing optimal lead time and procurement flexibility. TZM5264B-GS18, 1N5264BUR-1, and CDLL5264B offer moderate availability (683, 998, and 833 pcs respectively). MMSZ5264B-TP provides 827 pcs. Selection should balance electrical equivalence, package compatibility, compliance requirements, and procurement volume needs.
