Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP2996LQX is determined by strict alignment across the following critical parameters:

• Functional Application: DDR Terminator
• Package Type: 16-WQFN (4x4) with exposed pad
• Mounting Technology: Surface Mount
• Electrical Specifications: Supply voltage range 2.2V ~ 5.5V, supply current 320µA
• Operating Temperature Range: 0°C ~ 125°C
• Manufacturer: Texas Instruments (same device family)
• Base Product Number: LP2996

The LP2996LQX/NOPB is a direct substitute manufactured by Texas Instruments under the same base product number (LP2996) with identical electrical and mechanical specifications. The primary distinction is packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The LP2996LQX/NOPB is a direct functional and mechanical equivalent to the LP2996LQX. Both components share identical electrical specifications, package geometry, and DDR termination application requirements.

Product Status Consideration: The LP2996LQX is classified as Obsolete, while the LP2996LQX/NOPB maintains Active product status. For new designs or long-term procurement strategies, the LP2996LQX/NOPB is the preferred selection due to ongoing manufacturer support and availability.

Compliance Consideration: The LP2996LQX/NOPB achieves ROHS3 compliance, whereas the original LP2996LQX is RoHS non-compliant. Organizations subject to RoHS regulatory requirements should prioritize the LP2996LQX/NOPB variant.

Packaging Format: The LP2996LQX/NOPB is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original LP2996LQX is available in bulk packaging. Component selection should align with production volume and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can LP2996LQX/NOPB be used as a direct replacement for LP2996LQX in existing designs?

A: Yes. Both components are electrically and mechanically identical. The LP2996LQX/NOPB operates across the same supply voltage range (2.2V ~ 5.5V), maintains identical supply current specifications (320µA), and functions within the same operating temperature range (0°C ~ 125°C). Pin configuration and package footprint are identical for the 16-WQFN (4x4) form factor.

Q: What is the primary difference between LP2996LQX and LP2996LQX/NOPB?

A: The primary differences are product status, RoHS compliance classification, and packaging format. The LP2996LQX is Obsolete and RoHS non-compliant, supplied in bulk. The LP2996LQX/NOPB is Active, ROHS3 compliant, and supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both components maintain identical supply current (320µA) and operate across the same voltage range (2.2V ~ 5.5V) and temperature range (0°C ~ 125°C). Thermal and electrical performance characteristics are equivalent.

Q: Which variant should be selected for new product designs?

A: The LP2996LQX/NOPB is recommended for new designs. It carries Active product status, ensuring ongoing manufacturer support and availability. Additionally, ROHS3 compliance aligns with current regulatory requirements in most markets.

Q: Is the 16-WQFN (4x4) package footprint identical between both parts?

A: Yes. Both LP2996LQX and LP2996LQX/NOPB use the identical 16-WFQFN Exposed Pad package with 16-WQFN (4x4) supplier device package designation. PCB layout and assembly tooling are directly compatible.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.
