LM2695SDX Equivalent & Substitute Parts

Part Overview

The LM2695SDX is a buck switching regulator IC from Texas Instruments designed for step-down voltage conversion applications. It delivers positive adjustable output from 2.5V to 24V with a maximum output current of 1.25A, operating across an input voltage range of 8V to 30V. The device is housed in a 10-WDFN exposed pad surface mount package.

The LM2695SDX is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM2695SDX is determined by strict equivalence across the following critical parameters:

• Function and topology (step-down buck converter)
• Output configuration (positive adjustable)
• Input voltage range (8V to 30V minimum and maximum)
• Output voltage range (2.5V to 24V)
• Output current capability (1.25A)
• Number of outputs (single output)
• Synchronous rectifier configuration (non-synchronous)
• Operating temperature range (-40°C to 125°C)
• Package type (10-WDFN exposed pad / 10-WSON 4x4)
• Mounting technology (surface mount)

The LM2695SDX/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (tape and reel versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The LM2695SDX/NOPB is the direct functional equivalent of the LM2695SDX. Both devices share identical electrical characteristics and package specifications, ensuring pin-for-pin and functional compatibility.

The LM2695SDX/NOPB is preferred for new designs and ongoing production due to its active product status. Additionally, the LM2695SDX/NOPB meets ROHS3 compliance requirements, whereas the original LM2695SDX is RoHS non-compliant. This compliance difference is significant for applications subject to environmental and regulatory standards.

The packaging format difference (tape and reel versus bulk) affects procurement and assembly processes but does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the LM2695SDX/NOPB be used as a direct replacement for the LM2695SDX?

A: Yes. The LM2695SDX/NOPB is electrically and functionally identical to the LM2695SDX. Both devices feature the same input voltage range (8V to 30V), output voltage range (2.5V to 24V), output current (1.25A), operating temperature range (-40°C to 125°C), and 10-WSON package configuration. Pin-for-pin substitution is valid.

Q: What is the difference between LM2695SDX and LM2695SDX/NOPB?

A: The primary differences are product status, RoHS compliance, and packaging format. The LM2695SDX is obsolete and RoHS non-compliant, while the LM2695SDX/NOPB is active and ROHS3 compliant. The LM2695SDX/NOPB is supplied in tape and reel format, whereas the LM2695SDX is supplied in bulk packaging. Electrical specifications are identical.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both the LM2695SDX and LM2695SDX/NOPB use the 10-WDFN exposed pad package (10-WSON 4x4). PCB footprints, thermal characteristics, and mounting requirements are identical. No layout or assembly modifications are required.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance restricts the use of hazardous substances in electrical and electronic equipment. The LM2695SDX/NOPB meets ROHS3 standards, making it suitable for applications and markets with environmental regulations. The original LM2695SDX, being RoHS non-compliant, may face restrictions in certain jurisdictions or customer specifications.

Q: Can the LM2695SDX be used in new designs?

A: The LM2695SDX is classified as obsolete. For new designs, the LM2695SDX/NOPB is the recommended choice due to its active status, RoHS3 compliance, and assured long-term availability.
