BA00ASFP-E2 Equivalent & Substitute Parts

Part Overview

The BA00ASFP-E2 is a linear voltage regulator IC from Rohm Semiconductor designed for positive adjustable output applications. It delivers 1A output current in a surface-mount TO-252-5 package and includes integrated protection features for over-current, over-temperature, and over-voltage conditions. The device is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA00ASFP-E2 is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive Adjustable)
• Output current rating (1A)
• Input voltage maximum (25V)
• Output voltage range (1.225V to 25V)
• Package type (TO-252-5)
• Protection features (Over Current, Over Temperature, Over Voltage)
• Control features (Enable function)
• Quiescent current (2.5 mA)
• PSRR specification (55dB at 120Hz)

The BA00CC0WFP-E2 meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The BA00CC0WFP-E2 is the direct substitute for the BA00ASFP-E2. Both devices are manufactured by Rohm Semiconductor and share identical electrical and mechanical specifications across all critical parameters. The BA00CC0WFP-E2 offers two distinct advantages: it maintains active product status, ensuring long-term availability and supply chain stability, and it extends the maximum operating temperature range to 125°C compared to the 85°C limit of the BA00ASFP-E2. Both parts maintain ROHS3 compliance and identical RoHS/REACH certifications. Selection of the BA00CC0WFP-E2 is appropriate for applications requiring component continuity and compliance with current manufacturing standards.
