Key Parameters

Substitute Part Grouping Explanation

Substitute part grouping for Zener diodes is determined by matching the following key parameters: Zener voltage (Vz), power rating, impedance (Zzt), reverse leakage current, tolerance, operating temperature range, mounting type, package/case, RoHS status, MSL, and REACH status. Compliance with these parameters ensures functional equivalence and compatibility within the same application category.

Parameter Comparison

Engineering Selection Recommendations

The LZ52C27W Zener diode is designated as Obsolete. Substitute part BZT52C27-7-F from Diodes Incorporated is active and matches all relevant compliance standards, including ROHS3 and REACH unaffected status, and features the same power rating and Zener voltage. Adjustments to tolerance and package type must be noted. Both devices maintain MSL 1 rating, supporting unlimited shelf life.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the LZ52C27W Zener diode?
A1: The critical parameters for substitution are Zener voltage (Vz), power rating, maximum impedance (Zzt), reverse leakage current, tolerance, mounting type, package or case specification, operating temperature, and regulatory compliance.

Q2: Does the substitute part BZT52C27-7-F offer the same Zener voltage and power rating?
A2: Yes, BZT52C27-7-F provides a nominal Zener voltage of 27 V and a maximum power rating of 500 mW, matching those of LZ52C27W.

Q3: Is there a difference in package type between the main part and the substitute?
A3: The LZ52C27W is specified in a 1206 (3216 Metric) package, while BZT52C27-7-F uses the SOD-123 package. Both are surface mount configurations but have different footprint dimensions.

Q4: How do tolerance variations affect substitution?
A4: LZ52C27W features a ±2% tolerance and BZT52C27-7-F features ±7%. Tolerance must be considered for precision applications where voltage deviation limits are critical.

Q5: Are both parts compliant with ROHS3 and REACH standards?
A5: Both LZ52C27W and BZT52C27-7-F are ROHS3 Compliant and REACH Unaffected, supporting environmental and regulatory requirements.

Q6: What is the Moisture Sensitivity Level (MSL) for these parts?
A6: Both parts meet MSL 1 (Unlimited), indicating suitability for unprotected storage and standard assembly environments without special handling requirements.
