Key Parameters

Substitute Part Grouping Explanation

The substitution logic for diode arrays in the TO-244AB package prioritizes matching diode configuration, technology type, chassis mount format, reverse voltage rating, average rectified current rating, recovery speed, operating junction temperature range, and supplier device package. This ensures electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MBRF20045 and 201CNQ045 are classified as obsolete. 201CNQ045 maintains compliance documentation, including ROHS3 and REACH, with MSL 1 (Unlimited). When selecting a diode array replacement, assess the product status and compliance documentation for regulatory or qualification requirements in the end application. Both reference parts meet ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting the MBRF20045 Schottky diode array?
A1: Key parameters include technology type (Schottky), diode configuration (1 Pair Common Cathode), reverse voltage rating (45 V), average rectified current (per diode), forward voltage at specified current, reverse leakage current, recovery speed, junction operating temperature range, mounting type (Chassis Mount), and package/case (TO-244AB).

Q2: Are alternate diode arrays in different packages compatible with MBRF20045?
A2: Compatibility is limited to parts in a TO-244AB package with chassis mount to ensure identical mechanical fit and mounting.

Q3: Do compliance certifications affect substitution for obsolete rectifier diodes?
A3: Compliance documentation such as ROHS and REACH, and MSL ratings, must be verified as per inventory and procurement requirements within the specified standards.

Q4: Is it necessary to match both electrical and mechanical parameters for substitute selection?
A4: Yes, matching both sets of parameters is required for electrical performance and physical compatibility. Only the listed fields should be considered for substitution.

Q5: Does obsolete status affect the selection of 201CNQ045 as a substitute?
A5: Both main and substitute parts are obsolete. Selection for legacy designs will depend on inventory availability and compliance status as provided.
