Equivalent & Substitute Parts for DB3X316J0L

Part Overview

The DB3X316J0L is a Schottky diode array manufactured by Panasonic Electronic Components, configured as a 1 Pair Common Anode device rated for 30 V DC reverse voltage and 100 mA average rectified current per diode. The component is housed in a TO-236-3 (SC-59, SOT-23-3) surface mount package and is classified as discontinued at DiGi Electronics. Identification of equivalent and substitute parts is necessary due to product discontinuation and the need for continued design support and procurement alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB3X316J0L is determined by the following critical parameters: diode configuration (1 Pair Common Anode), mounting type (Surface Mount), package compatibility (TO-236-3 / SOT-23-3), voltage rating (minimum 30 V DC reverse), and current rating (minimum 100 mA per diode).

Substitute parts are grouped into two categories based on technology type:

Category 1: Schottky Technology Substitutes maintain the same Schottky diode technology as the original part. These substitutes include RB717UMTL and RB717UMFHTL from Rohm Semiconductor. While these parts exceed the voltage rating (40 V) and have reduced current ratings (30 mA), they preserve the Schottky technology characteristics and are suitable for applications where lower current requirements are acceptable.

Category 2: Standard Diode Technology Substitutes use standard diode technology instead of Schottky. These substitutes include MMBD2835LT1G and SMMBD2835LT1G from onsemi. These parts maintain the same package format (TO-236-3 / SOT-23-3), exceed the voltage rating (35 V), and match the current rating (100 mA per diode). Standard diodes exhibit different forward voltage characteristics and reverse recovery behavior compared to Schottky devices.

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Compatibility (TO-236-3 / SOT-23-3):

MMBD2835LT1G and SMMBD2835LT1G from onsemi are the primary substitutes when package footprint compatibility is required. Both parts are Active products with ROHS3 compliance and maintain the identical TO-236-3 (SOT-23-3) package format. These standard diode array devices provide 35 V reverse voltage rating and 100 mA current rating, exceeding the original specifications. The extended operating temperature range (-55°C to 150°C) provides broader thermal performance compared to the DB3X316J0L. MMBD2835LT1G is available in Tape & Reel packaging, while SMMBD2835LT1G is available in alternative packaging configurations.

For Schottky Technology Preservation:

RB717UMTL from Rohm Semiconductor is an Active product that maintains Schottky diode technology with ROHS3 compliance and AEC-Q101 automotive qualification. This part operates at 40 V reverse voltage and 30 mA current rating. The SC-85 package differs from the original TO-236-3 format and requires PCB layout modification. RB717UMFHTL is an equivalent Schottky option with "Not For New Designs" status and should not be selected for new applications.

Compliance and Availability:

All substitute parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. MMBD2835LT1G and SMMBD2835LT1G demonstrate the highest inventory availability and Active product status, making them the preferred choices for procurement continuity. RB717UMTL provides an alternative for applications requiring Schottky technology characteristics and automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can MMBD2835LT1G or SMMBD2835LT1G directly replace DB3X316J0L without circuit modification?

A: Both onsemi parts maintain identical package format (TO-236-3 / SOT-23-3) and pinout compatibility as 1 Pair Common Anode diode arrays. Direct PCB substitution is possible. However, the forward voltage characteristic differs (1.2 V versus 550 mV at 100 mA), which may affect circuit performance in applications sensitive to voltage drop. Circuit validation is required to confirm functional compatibility.

Q: Why do RB717UMTL and RB717UMFHTL have lower current ratings (30 mA versus 100 mA)?

A: The RB717 series from Rohm Semiconductor is designed for lower current applications. These Schottky devices are not suitable as direct substitutes for circuits requiring the full 100 mA per diode rating. Selection of RB717 parts is appropriate only when application current requirements do not exceed 30 mA per diode.

Q: What is the package difference between TO-236-3 and SC-85?

A: TO-236-3 (also designated SC-59 or SOT-23-3) is a 3-lead surface mount package with 1.9 mm pitch. SC-85 (UMD3F) is a different surface mount package format used by Rohm Semiconductor. PCB layout and footprint modifications are required when substituting between these package types.

Q: Are there differences in reverse recovery time between the substitute options?

A: MMBD2835LT1G and SMMBD2835LT1G (standard diodes) exhibit 4 ns reverse recovery time, compared to 800 ps for the original DB3X316J0L Schottky device. This represents a significant difference in switching speed. Applications requiring fast switching characteristics should retain Schottky technology using RB717UMTL, accepting the reduced current rating.

Q: What is the significance of "Not For New Designs" status for RB717UMFHTL?

A: RB717UMFHTL carries a "Not For New Designs" product status, indicating that Rohm Semiconductor does not recommend this part for new circuit designs. RB717UMTL is the Active equivalent and should be selected for new applications requiring Schottky technology in the RB717 series.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. MMBD2835LT1G, SMMBD2835LT1G, RB717UMTL, and RB717UMFHTL all carry ROHS3 compliance status. The original DB3X316J0L is RoHS Compliant. All parts meet environmental regulatory requirements for lead-free manufacturing.
