Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF2535CT-E3/45 is determined by compatibility across the following critical parameters:

Configuration & Package Compatibility:

• Diode configuration must remain 1 Pair Common Cathode
• Package type must be TO-220-3 Full Pack with isolated tab
• Mounting type must be Through Hole

Electrical Performance Criteria:

• Technology must be Schottky
• Forward voltage (Vf) must be equivalent or lower
• Reverse leakage current characteristics must be compatible
• Speed classification must maintain Fast Recovery characteristics

Voltage & Current Ratings:

• Reverse voltage rating may be equal to or greater than 35 V
• Average rectified current per diode may be equal to or greater than 15 A

Compliance & Environmental:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• Operating temperature range must encompass -65°C ~ 150°C

The MBRF2545CT-E3/45 qualifies as a substitute based on these parameters. It maintains identical configuration, package, and compliance specifications while providing higher voltage rating (45 V) and compatible electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MBRF2545CT-E3/45

The MBRF2545CT-E3/45 is the manufacturer-recommended substitute for the obsolete MBRF2535CT-E3/45. This part maintains full mechanical and electrical compatibility while offering enhanced specifications.

Compliance & Availability: The MBRF2545CT-E3/45 carries Active product status with 1427 units in stock, ensuring supply chain continuity. Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings of 1 (Unlimited).

Electrical Compatibility: The substitute part provides a higher DC reverse voltage rating of 45 V compared to the original 35 V specification. This represents a design margin improvement for applications operating at or near the original voltage limits. Forward voltage characteristics remain identical at 820 mV @ 30 A, and reverse leakage current specifications are maintained at 200 µA at the respective voltage ratings.

Current Rating Consideration: The MBRF2545CT-E3/45 is rated for 12.5 A average rectified current per diode, compared to 15 A for the original part. Applications requiring the full 15 A rating must evaluate whether the 12.5 A specification meets circuit requirements. For applications operating below 12.5 A, this specification difference is not a limiting factor.

Package & Mounting: Both parts utilize identical TO-220-3 Full Pack with isolated tab packaging and through-hole mounting, ensuring direct mechanical compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the MBRF2545CT-E3/45 directly replace the MBRF2535CT-E3/45 without PCB modifications?

A: Yes. Both parts share identical TO-220-3 Full Pack with isolated tab packaging and through-hole mounting specifications. No PCB layout changes are required for mechanical compatibility.

Q: What is the significance of the higher 45 V rating on the substitute part?

A: The MBRF2545CT-E3/45 provides a higher DC reverse voltage rating of 45 V versus 35 V on the original part. This allows operation in circuits with higher voltage transients or margins. Applications designed for 35 V operation remain fully compatible with the 45 V rated substitute.

Q: Does the 12.5 A current rating on the substitute affect my application?

A: The MBRF2545CT-E3/45 is rated for 12.5 A average rectified current per diode, compared to 15 A on the original part. Substitution is appropriate for applications operating at or below 12.5 A. Applications requiring the full 15 A rating must confirm that circuit current demands do not exceed the substitute part's specification.

Q: Are the forward voltage characteristics identical between the two parts?

A: Yes. Both the MBRF2535CT-E3/45 and MBRF2545CT-E3/45 specify a maximum forward voltage of 820 mV @ 30 A. Forward voltage performance is equivalent between the two parts.

Q: What is the difference in reverse leakage current between the parts?

A: The MBRF2535CT-E3/45 specifies 200 µA @ 35 V, while the MBRF2545CT-E3/45 specifies 200 µA @ 45 V. The leakage current magnitude is identical; the difference reflects measurement at the respective voltage ratings of each part.

Q: Is the MBRF2545CT-E3/45 available in the same packaging as the original part?

A: Yes. The substitute part is supplied in Tube packaging and maintains the identical TO-220-3 Full Pack with isolated tab configuration. The supplier device package designation ITO-220AB is identical for both parts.

Q: What is the product status difference between these parts?

A: The MBRF2535CT-E3/45 is classified as Obsolete, while the MBRF2545CT-E3/45 carries Active product status. The active status of the substitute ensures ongoing availability and manufacturing support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MBRF2535CT-E3/45 and MBRF2545CT-E3/45 are ROHS3 compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). Compliance specifications are identical between the two parts.
