Key Parameters

Substitute Part Grouping Explanation

Substitution for the ZMM5260B-13 Zener diode requires a candidate with exact or matching key parameters, specifically: zener voltage (43 V), tolerance (±5%), power rating (500 mW), impedance (93 Ohms), reverse leakage (100 nA @ 33 V), forward voltage (Vf) at 200 mA, operating temperature range (-65°C ~ 175°C), mounting type (Surface Mount), and package type (DO-213AA or Mini MELF). Additional considerations include RoHS compliance and identical supplier package where possible. Only substitute parts meeting all these parameters are included.

Parameter Comparison

No other certifications or compliance criteria are given in the provided data.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if 1N5260BUR-1/TR is an equivalent substitute for ZMM5260B-13?
A1: Only substitute parts with matching zener voltage, tolerance, power rating, impedance, reverse leakage, forward voltage at specified current, operating temperature range, mounting type, and package are considered equivalent.

Q2: Is the package for 1N5260BUR-1/TR fully compatible with designs intended for ZMM5260B-13?
A2: Both parts use the DO-213AA (Mini MELF) surface mount package, ensuring mechanical compatibility for PCB designs specified by the package.

Q3: Are there any differences in electrical performance between the two parts?
A3: All specified key parameters provided are equivalent, except for the forward voltage at 200 mA, which is 1.5 V (ZMM5260B-13) versus 1.1 V (1N5260BUR-1/TR).

Q4: What are the compliance and availability considerations?
A4: The 1N5260BUR-1/TR is listed as an active product status part, and both parts have similar MSL ratings. RoHS status is specified for ZMM5260B-13; no contradictory information is provided for the substitute.

Q5: Can these parts be interchanged in automated assembly processes?
A5: Both devices have the same mounting type and package specifications, supporting direct interchangeability in surface mount assembly where DO-213AA is specified.
