BA25BC0WFP-E2 Equivalent & Substitute Parts

Part Overview

The BA25BC0WFP-E2 is a linear voltage regulator IC manufactured by ROHM Semiconductor, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 2.5V at 1A maximum current in a surface-mount TO-252-5 package. The regulator features integrated protection against overcurrent, overtemperature, and short circuit conditions, with an enable control feature for power management applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

The part carries an ECCN classification of EAR99 and HTSUS code 8542.39.0001, confirming its status as a standard commercial electronic component without export restrictions. With MSL 1 rating, this device requires no special moisture control during storage or handling, supporting standard logistics and inventory management practices. Current inventory availability of 17,359 pieces in new original condition ensures supply continuity for immediate procurement requirements. Selection of this part is supported by its comprehensive protection feature set, including integrated overcurrent, overtemperature, and short circuit protection, which reduces external component requirements in power management circuit designs.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the BA25BC0WFP-E2?

A: A valid substitute must match all critical electrical parameters: 2.5V fixed positive output, 1A output current rating, 16V maximum input voltage, single regulator configuration, enable control feature, and integrated overcurrent/overtemperature/short circuit protection. The substitute must also use the TO-252-5 (DPAK) surface-mount package and operate across the -40°C to 105°C temperature range.

Q: Is the BA25BC0WFP-E2 compatible with other TO-252 package variants?

A: The BA25BC0WFP-E2 is specified for TO-252-5 (DPAK with 4 leads + tab), also designated as TO-252AD. Compatibility with other TO-252 variants depends on matching pin configuration and lead count. Mechanical fit alone does not ensure electrical compatibility; all electrical parameters must align with the application requirements.

Q: What is the significance of the MSL 1 rating for this component?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. This component does not require special dry-pack storage, desiccant handling, or bake-out procedures before soldering, simplifying procurement and manufacturing logistics.

Q: Does the BA25BC0WFP-E2 require external protection components?

A: The BA25BC0WFP-E2 integrates overcurrent, overtemperature, and short circuit protection internally. External protection components may still be required based on specific application circuit design, input source characteristics, and output load conditions, but the regulator itself provides comprehensive internal safeguards.

Q: What is the REACH compliance status of this part?

A: The BA25BC0WFP-E2 carries REACH Unaffected status, indicating it does not contain substances of very high concern (SVHC) listed under REACH regulations and requires no special compliance documentation for European Union supply chains.
