Key Parameters

Substitute Part Grouping Explanation

The BCR430UXTSA1 has one parametric equivalent identified based on strict electrical and mechanical compatibility criteria. Substitution eligibility is determined by the following key parameters:

• Linear topology with constant current output
• Single output configuration
• 6V to 42V supply voltage range
• 100mA output current per channel
• PWM dimming capability
• SOT-23-6 package form factor
• Operating temperature range of -40°C to 150°C
• ROHS3 compliance and MSL Level 1 rating

The substitute part BCR430UXTSA2 matches all these critical parameters, differing only in product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The BCR430UXTSA2 is the direct parametric equivalent for the obsolete BCR430UXTSA1. Both parts are manufactured by Infineon Technologies and maintain identical electrical specifications, thermal ratings, and compliance certifications. The primary distinction is product status: BCR430UXTSA2 is actively produced and available in higher inventory quantities (9079 pcs vs. 1118 pcs), making it the appropriate selection for new designs and production continuity.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The MSL Level 1 rating indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can BCR430UXTSA2 be used as a direct replacement for BCR430UXTSA1?

A: Yes. Both parts are electrically and mechanically identical, with matching supply voltage ranges (6V–42V), output current (100mA), PWM dimming capability, and SOT-23-6 package specifications. The difference is packaging format and product lifecycle status.

Q: What is the difference between the two part numbers?

A: The BCR430UXTSA1 is supplied in standard packaging and is classified as obsolete. The BCR430UXTSA2 is the active production variant supplied in Tape & Reel format. Both share the same die and electrical performance.

Q: Are there any thermal or operating condition differences?

A: No. Both parts operate across -40°C to 150°C junction temperature and maintain identical thermal characteristics.

Q: What are the compliance and regulatory considerations?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. No additional compliance actions are required when substituting between these parts.

Q: Is the SOT-23-6 package identical between both parts?

A: Yes. Both parts use the SOT-23-6 package form factor with identical pinout and mechanical dimensions, ensuring direct PCB compatibility.
