Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC4212BMLTRC is determined by the following critical parameters:

• Manufacturer & Base Product Number: Same manufacturer (Semtech Corporation) and base product number (SC4212) ensures design compatibility and functional equivalence
• Output Configuration & Type: Positive adjustable (fixed) output with identical voltage range (0.5V to 5V)
• Current Rating: 1A output current capacity
• Package & Pinout: 8-VDFN Exposed Pad (8-MLPD 3x3) ensures mechanical and electrical compatibility
• Protection Features: Over-current, over-temperature, and reverse polarity protection
• Operating Temperature Range: -40°C ~ 125°C
• Compliance: RoHS compliant status

The SC4212MLTRT meets all substitution criteria. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and minor variations in quiescent current and dropout voltage specifications, which do not affect functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The SC4212MLTRT is a direct functional equivalent to the SC4212BMLTRC. Both parts share identical electrical specifications for output voltage range, output current capacity, protection features, and operating temperature range. Both are RoHS compliant with MSL Level 1 rating, ensuring equivalent environmental and regulatory compliance.

The SC4212MLTRC is designated "Not For New Designs," which necessitates the use of SC4212MLTRT for ongoing production and support applications. The substitute part is available in higher inventory (5920 pcs versus 2309 pcs) and offers improved quiescent current performance (15 µA versus 50 µA), making it suitable for applications requiring extended battery life or low-power standby operation.

The primary distinction between the two parts is packaging format: SC4212BMLTRC is supplied in Tape & Reel format, while SC4212MLTRT is available in Cut Tape and Digi-Reel format. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SC4212MLTRT be used as a direct replacement for SC4212BMLTRC in existing designs?

A: Yes. Both parts are identical in electrical function, output voltage range (0.5V to 5V), output current (1A), package type (8-VDFN Exposed Pad), and protection features. The pinout and footprint are identical, enabling direct substitution without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) supplies components on continuous carrier tape wound on a reel for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel supplies the same components on cut tape segments or alternative reel formats. Both formats contain identical components; the difference is in packaging and handling for assembly operations.

Q: Are there any performance differences between SC4212BMLTRC and SC4212MLTRT?

A: The substitute part exhibits lower quiescent current (15 µA versus 50 µA) and higher dropout voltage (0.5V versus 0.15V @ 1A). The lower quiescent current is beneficial for low-power applications. The higher dropout voltage may require consideration in applications with tight input-to-output voltage margins, though both remain within acceptable operating parameters for standard 1A linear regulator applications.

Q: Are both parts RoHS compliant?

A: Yes. Both SC4212BMLTRC and SC4212MLTRT are RoHS compliant with MSL Level 1 rating, meeting equivalent environmental and regulatory requirements.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that Semtech Corporation is not recommending the SC4212BMLTRC for new product development. For ongoing support of existing designs or new applications, SC4212MLTRT should be selected as the current equivalent part.
