Substitute Part Grouping Explanation

Substitution of the DDZX36-7 is permissible with the DDZX36-13 based on the following criteria:

Electrical Equivalence:

• Identical nominal Zener voltage: 36.9 V
• Identical voltage tolerance: ±3%
• Identical maximum power rating: 300 mW
• Identical maximum impedance: 85 Ohms
• Identical reverse leakage current: 50 nA @ 30 V
• Identical forward voltage: 900 mV @ 10 mA

Mechanical Compatibility:

• Identical package designation: SOT-23-3 (TO-236-3, SC-59)
• Identical mounting type: Surface Mount
• Identical supplier device package: SOT-23-3

Compliance Alignment:

• Both parts maintain RoHS3 compliance
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected
• Both parts carry identical ECCN and HTSUS classifications

The DDZX36-13 functions as a direct parametric equivalent within the DDZX36 base product family, differing only in internal manufacturing or date code designation.

Parameter Comparison

Engineering Selection Recommendations

Both DDZX36-7 and DDZX36-13 are active products manufactured by Diodes Incorporated with full RoHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by availability and supply chain requirements rather than functional differences.

The DDZX36-7 maintains current inventory of 3200 pieces. The DDZX36-13 maintains current inventory of 812 pieces. Both parts satisfy identical design requirements for 36.9 V Zener diode applications in SOT-23-3 surface mount configurations.

Compliance certifications (RoHS3, REACH Unaffected, MSL 1) are equivalent across both part numbers, ensuring regulatory alignment in manufacturing and deployment environments.

Frequently Asked Questions (FAQ)

Q: Can DDZX36-13 be used as a direct replacement for DDZX36-7 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical specifications (36.9 V nominal voltage, 300 mW power rating, ±3% tolerance, 85 Ohms impedance) and mechanical characteristics (SOT-23-3 package, surface mount). No circuit modifications are required.

Q: Are there differences in package dimensions between DDZX36-7 and DDZX36-13?

A: No. Both parts use the identical SOT-23-3 package designation (also referenced as TO-236-3 or SC-59). PCB footprints and assembly processes remain unchanged.

Q: What is the difference between DDZX36-7 and DDZX36-13 if all parameters are identical?

A: The parts share the same base product number (DDZX36) and differ only in manufacturing lot or date code designation. The suffix variation (-7 versus -13) does not reflect functional or electrical differences.

Q: Are both parts RoHS3 compliant?

A: Yes. Both DDZX36-7 and DDZX36-13 carry RoHS3 compliance certification and are REACH Unaffected, meeting identical regulatory requirements.

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

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

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain identical operating temperature range specifications of -65°C to 150°C, supporting equivalent thermal performance across the full rated range.
