Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA3X704D0L is determined by the following critical parameters:

Primary Compatibility Criteria:

• Diode Configuration: 1 Pair Common Anode (mandatory)
• Technology: Schottky (mandatory)
• Voltage - DC Reverse (Vr) (Max): 30 V minimum (equal or higher acceptable)
• Package / Case: TO-236-3, SC-59, SOT-23-3 (mandatory for direct PCB compatibility)
• Mounting Type: Surface Mount (mandatory)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory)

Secondary Compatibility Criteria:

• Current - Average Rectified (Io) (per Diode): 30 mA minimum (equal or higher acceptable)
• Voltage - Forward (Vf) (Max) @ If: Electrical performance parameter
• Operating Temperature - Junction (Max): 125°C minimum (equal or higher acceptable)

Substitute parts meeting all primary criteria and equal or superior secondary criteria are electrically and mechanically compatible with the MA3X704D0L. Parts with higher current ratings, lower forward voltage, or higher temperature ratings represent functional upgrades within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Identical Package, Common Anode Configuration):

BAT54A,235 (Nexperia USA Inc.), BAT54A-TP (Micro Commercial Co), and BAT5406E6327HTSA1 (Infineon Technologies) are direct substitutes for the MA3X704D0L. All three components maintain the 1 Pair Common Anode configuration, TO-236-3 package footprint, 30 V reverse voltage rating, and MSL 1 classification. These parts feature 200 mA current ratings, exceeding the original 30 mA specification, and are classified as Active products with ROHS3 compliance.

BAT54A,235 and BAT754A,215 (both Nexperia) include automotive-grade qualifications (AEC-Q101 and AEC-Q100 respectively), suitable for applications requiring automotive component standards.

BAR43AFILM (STMicroelectronics) is a direct substitute with 100 mA current rating and Active product status. This component provides a mid-range current capacity between the original 30 mA and the 200 mA alternatives.

Tier 2 - Package Incompatible Substitute:

RB451FT106 (Rohm Semiconductor) is a single diode (not a diode array pair) housed in SC-70, SOT-323 package. This component is not a direct substitute due to different package footprint and diode configuration. Selection of this part requires PCB redesign and is not recommended for direct replacement applications.

Compliance and Availability:

All Tier 1 substitute parts are ROHS3 compliant and REACH unaffected. All maintain MSL 1 (Unlimited) moisture sensitivity classification. Inventory availability ranges from 2,138 to 197,400 units across substitute options, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can BAT54A,235 directly replace MA3X704D0L on the same PCB?

A: Yes. BAT54A,235 maintains identical package geometry (TO-236-3, SC-59, SOT-23-3), diode configuration (1 Pair Common Anode), and reverse voltage rating (30 V). The component is pin-compatible and requires no PCB modifications.

Q: What is the difference between BAT54A,235 and BAT754A,215?

A: Both are Nexperia Schottky diode arrays in TO-236-3 packages with 1 Pair Common Anode configuration and 30 V reverse voltage. BAT754A,215 features lower forward voltage (600 mV @ 100 mA versus 800 mV @ 100 mA) and carries AEC-Q100 automotive qualification. BAT54A,235 carries AEC-Q101 qualification. Forward voltage difference may impact power dissipation in high-current applications.

Q: Why is RB451FT106 listed as a substitute if it has a different package?

A: RB451FT106 is listed based on the provided input parameters but is not a direct substitute. The component features a different package (SC-70, SOT-323 versus TO-236-3), different diode configuration (single diode versus 1 Pair Common Anode), and different package footprint. Selection of this part requires PCB redesign and is not recommended for direct replacement.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Tier 1 substitute parts (BAR43AFILM, BAT5406E6327HTSA1, BAT54A,235, BAT54A-TP, BAT754A,215) are ROHS3 compliant. The original MA3X704D0L RoHS status is not specified in available documentation.

Q: What is the current rating difference between MA3X704D0L and substitute parts?

A: The MA3X704D0L is rated for 30 mA average rectified current per diode. Substitute parts offer higher current ratings: BAR43AFILM (100 mA), BAT5406E6327HTSA1 (200 mA), BAT54A,235 (200 mA), BAT54A-TP (200 mA), and BAT754A,215 (200 mA). Higher current ratings provide design margin and are electrically compatible with applications designed for 30 mA operation.

Q: Do substitute parts require different soldering or assembly procedures?

A: No. All Tier 1 substitute parts maintain identical Surface Mount package classification (TO-236-3, SC-59, SOT-23-3) and MSL 1 (Unlimited) moisture sensitivity level. Standard surface mount assembly procedures apply without modification.

Q: Which substitute part offers the lowest forward voltage?

A: BAT754A,215 (Nexperia) features the lowest forward voltage at 600 mV @ 100 mA, followed by BAT5406E6327HTSA1 (Infineon) at 800 mV @ 100 mA. Lower forward voltage reduces power dissipation in rectification applications.

Q: Are automotive-qualified alternatives available?

A: Yes. BAT54A,235 (AEC-Q101 qualified) and BAT754A,215 (AEC-Q100 qualified) are automotive-grade Schottky diode arrays suitable for automotive applications requiring component qualification standards.
