SI-3010LLSL Equivalent & Substitute Parts

Part Overview

The SI-3010LLSL is a linear voltage regulator IC manufactured by Sanken Electric USA Inc., designed for positive adjustable output applications. This 8-SOP surface mount device delivers 1.5A output current with adjustable voltage regulation from 1V to 3.3V and a maximum dropout voltage of 0.3V at 1A. The device includes integrated over-current and over-temperature protection with enable control features.

The SI-3010LLSL is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance of systems utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI-3010LLSL are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Identical output configuration (positive adjustable)
• Matching voltage specifications (input max 3.6V, output range 1V to 3.3V)
• Equivalent current ratings (1.5A output)
• Identical dropout voltage performance (0.3V @ 1A)
• Matching package type (8-SOIC surface mount)
• Equivalent protection and control features (over-current, over-temperature, enable control)
• Identical operating temperature range (-20°C ~ 100°C)
• RoHS compliance status

The SI-3010LLSL-TL qualifies as a parametric equivalent substitute. Both parts share the same base product number (SI-3010), identical electrical specifications, and equivalent mechanical packaging. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. This distinction affects supply chain logistics but does not impact electrical or functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SI-3010LLSL and SI-3010LLSL-TL are classified as obsolete products. Selection between these parts should be based on supply chain availability and packaging requirements rather than electrical performance, as all functional parameters are identical.

The SI-3010LLSL-TL offers higher current inventory availability (3100 pcs vs. 801 pcs), making it the preferred choice for volume production or long-term supply assurance. The Cut Tape packaging format is suitable for automated pick-and-place assembly processes and reduces material waste compared to Tape & Reel format.

Both parts maintain RoHS compliance and identical moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols. The identical operating temperature range (-20°C ~ 100°C) and protection features support equivalent performance in target applications.

Frequently Asked Questions (FAQ)

Q: Are SI-3010LLSL and SI-3010LLSL-TL electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including voltage regulation range, current output, dropout voltage, quiescent current, PSRR, and protection features. They are direct functional substitutes.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume orders or mixed-component assembly. Both formats use identical component specifications and 8-SOIC package dimensions.

Q: Can I use SI-3010LLSL-TL as a direct replacement in existing designs?

A: Yes. The SI-3010LLSL-TL is a direct replacement with no design modifications required. PCB footprints, pin configurations, and electrical performance are identical. Only the supply format differs.

Q: Are both parts RoHS compliant?

A: Yes. Both SI-3010LLSL and SI-3010LLSL-TL are RoHS compliant with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: Why are both parts classified as obsolete?

A: Product status reflects manufacturer discontinuation. However, both parts remain available through authorized distributors with current inventory stock.

Q: Which part should I select for new production?

A: SI-3010LLSL-TL is recommended for new production due to higher inventory availability and Cut Tape packaging compatibility with standard automated assembly equipment.
