Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL751L05CDG4 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution compatibility are:

• Output voltage specification (5V fixed)
• Maximum output current (150mA)
• Input voltage rating (26V maximum)
• Package type (8-SOIC surface mount)
• Dropout voltage performance (0.6V @ 150mA)
• Protection feature set (over-current, over-temperature, over-voltage, reverse polarity)
• Operating temperature range (0°C ~ 125°C)

Parts matching all these parameters across the same manufacturer series are classified as direct substitutes. The TL751L05CD meets all electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The TL751L05CD is the recommended substitute for the discontinued TL751L05CDG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications and package configurations. The TL751L05CD maintains active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with ROHS3 and REACH requirements, with MSL rating of 1 (Unlimited), making them suitable for standard manufacturing and storage conditions. The electrical performance characteristics, including dropout voltage, PSRR, and protection features, are equivalent across both parts.

The primary distinction is product status: the TL751L05CDG4 is discontinued, while the TL751L05CD remains in active production. For new designs and component procurement, the TL751L05CD is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the TL751L05CD directly replace the TL751L05CDG4 in existing designs?

A: Yes. The TL751L05CD is electrically and mechanically equivalent to the TL751L05CDG4. Both parts feature identical output voltage (5V), current rating (150mA), package type (8-SOIC), and protection features. No circuit modifications are required for substitution.

Q: What is the difference between TL751L05CDG4 and TL751L05CD?
