Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1PMT5929C/TR13 are identified strictly based on matching or exceeding the primary electrical and mechanical criteria documented for Zener diodes in this category. These are: nominal Zener voltage, power rating, voltage tolerance, maximum impedance, reverse leakage current, forward voltage, surge and operating temperature, mounting type, and package. Additional compliance parameters such as RoHS, MSL, and REACH status are also considered for applications requiring environmental or regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

Selection between 1PMT5929C/TR13 and 1PMT5929BT1G should be based on product RoHS compliance requirements and environmental certifications, as both devices are actively available and meet matched electrical and mechanical characteristics within the allowed parameter tolerances. The 1PMT5929BT1G provides ROHS3 compliance and the same moisture sensitivity and REACH status.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when selecting a substitute for the 1PMT5929C/TR13 Zener diode?
A1: The critical parameters are nominal Zener voltage (15 V), tolerance (±2% or wider), maximum power dissipation (3 W or higher), maximum Zener impedance, reverse leakage current at specified voltage, forward voltage at specified current, operating temperature range, mounting type (surface mount), and package/case (DO-216AA). Regulatory and compliance fields such as RoHS and REACH status may also be required depending on the application.

Q2: Are the 1PMT5929C/TR13 and 1PMT5929BT1G fully interchangeable in terms of footprint and electrical properties?
A2: Both parts have a DO-216AA package and surface-mount configuration. They match in key electrical properties including Zener voltage, maximum power, leakage current, and operating temperature range, with variations in tolerance and forward voltage as per the provided parameters.

Q3: How do compliance parameters affect substitute selection?
A3: RoHS and REACH status directly impact selection for applications requiring compliance with environmental or market regulations. The 1PMT5929BT1G is ROHS3 compliant, while the 1PMT5929C/TR13 is RoHS non-compliant; both are REACH unaffected.

Q4: Is there any difference in moisture sensitivity between the 1PMT5929C/TR13 and recommended substitute?
A4: There is no difference in moisture sensitivity level; both are rated at MSL 1 (Unlimited).

Q5: How should package and mounting type be considered in substitutes for Zener diodes in this category?
A5: Only substitute Zener diodes using identical package/case and mounting types, such as DO-216AA and surface mount, to ensure mechanical and assembly compatibility without deviation from original design constraints.
