Key Parameters

Substitute Part Grouping Explanation

Substitution of the BD50C0AHFP-CTR is determined by strict equivalence across the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (1A)
• Maximum input voltage (26.5V)
• Dropout voltage performance (0.5V @ 500mA)
• Package type (TO-263-6 / D2PAK)
• Automotive qualification (AEC-Q100)
• Compliance certifications (ROHS3, REACH Unaffected)
• Operating temperature range (-40°C ~ 125°C)

The BD50C0AWHFP-CTR meets all these criteria and is classified as a parametric equivalent within the BD50C0 base product family. Both parts share identical electrical specifications, thermal performance, and regulatory compliance, differing only in internal manufacturing process variants that do not affect functional performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both BD50C0AHFP-CTR and BD50C0AWHFP-CTR are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences. Both parts maintain full compliance with ROHS3 and REACH regulations, and both carry AEC-Q100 automotive qualification. The BD50C0AWHFP-CTR currently has higher inventory availability (2788 units) compared to the BD50C0AHFP-CTR (2018 units), making it a viable alternative for procurement planning. Pin-to-pin compatibility and thermal performance are identical, ensuring direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can BD50C0AWHFP-CTR be used as a direct replacement for BD50C0AHFP-CTR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (5V), output current (1A), dropout voltage (0.5V @ 500mA), package type (TO-263-6), and operating temperature range (-40°C ~ 125°C). Pin configuration and thermal characteristics are identical.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry AEC-Q100 qualification and are suitable for automotive applications. Compliance certifications (ROHS3, REACH Unaffected) are identical.

Q: What determines substitution eligibility for this regulator?

A: Substitution is determined by matching output voltage (5V fixed), output current (1A), maximum input voltage (26.5V), package type (TO-263-6 / D2PAK), dropout voltage performance, and automotive qualification status. All these parameters must remain constant.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use the same TO-263-6 package footprint and pin configuration. No PCB layout modifications are required for substitution.

Q: What is the difference between the part number suffixes (AHFP vs AWHFP)?

A: The suffix variation indicates different manufacturing process nodes within the BD50C0 base product family. These process variants do not affect electrical performance, thermal characteristics, or functional behavior. Both parts meet identical specifications.

Q: Are there any supply chain advantages to selecting one part over the other?

A: The BD50C0AWHFP-CTR has higher current inventory (2788 units) compared to BD50C0AHFP-CTR (2018 units). For high-volume procurement or time-sensitive projects, the higher-stock variant may offer supply chain advantages.
