DB3J316N0L Equivalent & Substitute Parts

Part Overview

The DB3J316N0L is a Schottky diode array manufactured by Panasonic Electronic Components, configured as a 1 Pair Common Cathode device rated for 30 V DC reverse voltage and 100 mA average rectified current per diode. The device is packaged in SC-85 surface mount configuration and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

This part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the SC-85 package footprint and preserve the 1 Pair Common Cathode diode configuration while meeting or exceeding the electrical performance requirements of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB3J316N0L is determined by strict adherence to the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Diode Configuration: Must be 1 Pair Common Cathode
• Technology: Must be Schottky
• Package / Case: Must be SC-85 surface mount
• Mounting Type: Must be Surface Mount
• Operating Temperature - Junction: Must support 125°C maximum

Electrical Performance Parameters:

• Voltage - DC Reverse (Vr) (Max): Substitute must equal or exceed 30 V
• Current - Average Rectified (Io) (per Diode): Substitute must equal or exceed 100 mA
• Speed Classification: Must be Small Signal ≤ 200mA (Io), Any Speed

The substitute parts RB715UMFHTL and RB715UMTL are Rohm Semiconductor Schottky diode arrays with 1 Pair Common Cathode configuration in SC-85 package. Both devices meet the mechanical compatibility requirements and support the required operating temperature range. However, both substitute parts are rated for 40 V DC reverse voltage and 30 mA average rectified current per diode, which represents a reduction in current-handling capability compared to the original DB3J316N0L specification.

Engineering Selection Recommendations

RB715UMTL (Rohm Semiconductor) - Preferred Substitute

The RB715UMTL is the recommended substitute for the DB3J316N0L. This device maintains full mechanical compatibility with SC-85 surface mount packaging and preserves the 1 Pair Common Cathode Schottky diode configuration. The RB715UMTL carries Active product status, ensuring continued availability and supply chain stability. The device is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Inventory availability is confirmed at 4603 pieces in stock.

The RB715UMTL exhibits superior reverse voltage rating (40 V versus 30 V) and lower forward voltage characteristics (370 mV @ 1 mA versus 550 mV @ 100 mA). The primary electrical difference is the reduced average rectified current rating of 30 mA per diode compared to the original 100 mA specification. Circuit designs operating at or below 30 mA per diode will experience no functional degradation. Designs requiring current levels exceeding 30 mA per diode require circuit modification or alternative component selection.

RB715UMFHTL (Rohm Semiconductor) - Secondary Substitute

The RB715UMFHTL provides identical electrical specifications to the RB715UMTL but carries Not For New Designs product status. This designation indicates the manufacturer does not recommend this part for new circuit designs. The RB715UMFHTL is suitable only for maintenance and repair of existing equipment where component replacement is necessary. Inventory availability is limited at 1600 pieces in stock. New designs should utilize the RB715UMTL.

Frequently Asked Questions (FAQ)

Q: Can the RB715UMTL directly replace the DB3J316N0L without circuit modification?

A: The RB715UMTL is mechanically and functionally compatible with the DB3J316N0L in SC-85 surface mount applications. However, the reduced current rating (30 mA per diode versus 100 mA) requires verification that circuit operating currents do not exceed 30 mA per diode. If circuit design operates within this current limit, direct substitution is valid. If circuit design requires current levels exceeding 30 mA per diode, circuit modification is necessary.

Q: What is the significance of the SC-85 package designation?

A: SC-85 is the surface mount package classification for both the original DB3J316N0L and substitute parts RB715UMFHTL and RB715UMTL. This package designation ensures mechanical and electrical compatibility at the PCB footprint level. All three devices are interchangeable from a physical mounting perspective.

Q: Why does the RB715UMTL have a higher reverse voltage rating (40 V) than the DB3J316N0L (30 V)?

A: The RB715UMTL is rated for 40 V maximum DC reverse voltage, which exceeds the 30 V specification of the DB3J316N0L. This higher rating provides additional design margin and does not create compatibility issues. Circuits designed for 30 V operation will function correctly with a 40 V rated component.

Q: What is the difference between RB715UMFHTL and RB715UMTL?

A: Both devices are electrically and mechanically identical Rohm Semiconductor Schottky diode arrays with 1 Pair Common Cathode configuration in SC-85 package. The primary difference is product status: RB715UMFHTL is designated Not For New Designs, while RB715UMTL is Active. For new designs and ongoing production, RB715UMTL is the appropriate selection.

Q: Are the substitute parts RoHS compliant?

A: Both RB715UMFHTL and RB715UMTL are ROHS3 Compliant, meeting current RoHS requirements. The original DB3J316N0L is RoHS Compliant. All three devices satisfy RoHS compliance requirements for electronic component applications.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: Both RB715UMFHTL and RB715UMTL carry MSL 1 (Unlimited) rating, identical to the original DB3J316N0L. This classification indicates unlimited shelf life under normal storage conditions without moisture bake requirements prior to soldering.
