Substitute Part Grouping Explanation

Substitute parts for the RQ5RW20CA-TR-FE are identified based on strict parametric equivalence within the Rx5RW series. The substitution logic is based on the following critical parameters that must remain identical:

• Output Configuration: Positive
• Output Type: Fixed
• Voltage - Output (Min/Fixed): 2V
• Current - Output: 50mA
• Voltage - Input (Max): 8V
• Voltage Dropout (Max): 0.09V @ 1mA
• Current - Quiescent (Iq): 3 µA
• Control Features: Enable
• Protection Features: Over Current
• Operating Temperature: -40°C ~ 85°C
• Package / Case: SC-82A, SOT-343
• Supplier Device Package: SC-82AB
• Mounting Type: Surface Mount
• Packaging Format: Tape & Reel (TR)

Parts meeting all these criteria are considered direct parametric equivalents and can be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the RQ5RW20CA-TR-FE and RQ5RW20BA-TR-FE are active products from Nisshinbo Micro Devices Inc. with identical electrical and mechanical specifications. The RQ5RW20BA-TR-FE carries ROHS3 compliance certification, whereas the RQ5RW20CA-TR-FE carries standard RoHS compliance. The RQ5RW20BA-TR-FE additionally carries REACH Unaffected status. Both parts are manufactured in SC-82AB packaging (SOT-343) and supplied in Tape & Reel format. Selection between these parts should be based on specific regulatory requirements of the end application and supply chain availability. Both parts are suitable for applications requiring 2V fixed output linear regulation at 50mA with low quiescent current and over-current protection.

Frequently Asked Questions (FAQ)

Q: Can RQ5RW20BA-TR-FE be used as a direct replacement for RQ5RW20CA-TR-FE?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including output voltage, current rating, dropout voltage, operating temperature range, and package type. The primary difference is the RoHS certification level (ROHS3 vs. RoHS Compliant).

Q: Are there any package compatibility concerns when substituting between these parts?

A: No. Both parts use identical packaging: SC-82A case style with SOT-343 footprint, supplied in Tape & Reel format. PCB layout and assembly processes require no modification.

Q: What is the significance of the RoHS certification difference?

A: ROHS3 represents a more recent compliance standard. The RQ5RW20BA-TR-FE meets ROHS3 requirements, while the RQ5RW20CA-TR-FE meets standard RoHS requirements. Selection depends on the regulatory requirements of the target application and end market.

Q: Do both parts have identical quiescent current specifications?

A: Yes. Both parts specify 3 µA quiescent current, making them equivalent for low-power standby applications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C ~ 85°C) and maintain the same dropout voltage specification of 0.09V @ 1mA.

Q: What is the significance of the REACH Unaffected status on the RQ5RW20BA-TR-FE?

A: REACH Unaffected status indicates the part does not contain substances of very high concern (SVHC) listed under REACH regulations. This is relevant for applications subject to European Union regulatory requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. No circuit redesign, PCB layout modification, or assembly process changes are required when substituting between RQ5RW20CA-TR-FE and RQ5RW20BA-TR-FE.
