Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ2.7B,135 are classified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Zener voltage nominal value: 2.7 V
• Package type: SOD-323 (SC-76)
• Mounting configuration: Surface Mount
• Reverse leakage current: 20 µA @ 1 V

Secondary Compatibility Criteria:

• Maximum power dissipation rating
• Zener voltage tolerance
• Forward voltage characteristics
• Operating temperature range
• RoHS and REACH compliance status

Substitutes are grouped into two categories: Parametric Equivalents (identical electrical specifications and packaging) and Similar Alternatives (matching core voltage and package with acceptable variations in power rating and tolerance).

Parameter Comparison

Engineering Selection Recommendations

PDZ2.7B,115 (Parametric Equivalent): This part is a direct parametric equivalent to PDZ2.7B,135. Both components share identical electrical specifications, including 2.7 V nominal Zener voltage, ±2% tolerance, 400 mW maximum power rating, and 100 Ohms maximum impedance. Both are manufactured by Nexperia USA Inc., packaged in SOD-323, and carry ROHS3 compliance with MSL 1 rating. Selection between PDZ2.7B,135 and PDZ2.7B,115 is based on inventory availability and supply chain logistics, as electrical performance is equivalent.

MM3Z2V7T1G (Similar Alternative): This onsemi component maintains the 2.7 V nominal Zener voltage and SOD-323 package compatibility. However, it differs in three key parameters: maximum power dissipation is reduced to 300 mW (versus 400 mW), Zener voltage tolerance is ±7% (versus ±2%), and forward voltage is specified at 900 mV @ 10 mA (versus 1.1 V @ 100 mA). The MM3Z2V7T1G is suitable for applications where the 300 mW power rating is sufficient and the wider tolerance is acceptable. This component also provides an extended operating temperature range of -65°C to 150°C. All three parts maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can PDZ2.7B,115 be used as a direct replacement for PDZ2.7B,135?

A: Yes. PDZ2.7B,115 is a parametric equivalent with identical electrical specifications and packaging. Both components are manufactured by Nexperia USA Inc. and share the same 2.7 V nominal voltage, ±2% tolerance, 400 mW power rating, and SOD-323 package configuration.

Q: What are the limitations of using MM3Z2V7T1G as a substitute?

A: The MM3Z2V7T1G has a reduced maximum power dissipation of 300 mW compared to 400 mW for the PDZ2.7B,135. Additionally, the Zener voltage tolerance is ±7% rather than ±2%, which may impact voltage regulation precision in sensitive applications. The MM3Z2V7T1G is suitable only for designs where these specifications are acceptable.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three components use the SOD-323 package (SC-76), which provides identical mechanical and electrical interface characteristics for surface mount assembly.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. PDZ2.7B,135, PDZ2.7B,115, and MM3Z2V7T1G are all ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for high-precision voltage regulation applications?

A: PDZ2.7B,115 maintains the ±2% tolerance specification identical to PDZ2.7B,135 and is the appropriate choice for applications requiring tight voltage regulation. MM3Z2V7T1G, with ±7% tolerance, is not suitable for precision voltage reference applications.

Q: Is the extended temperature range of MM3Z2V7T1G a significant advantage?

A: The MM3Z2V7T1G operating range of -65°C to 150°C provides broader low-temperature capability compared to the 150°C maximum junction temperature of PDZ2.7B,135. This is relevant only for applications requiring operation below ambient temperature conditions.
