Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP2996MR is determined by strict alignment across the following critical parameters:

• Identical package and pinout: 8-PowerSOIC (0.154", 3.90mm Width)
• Matching voltage supply range: 2.2V ~ 5.5V
• Equivalent current supply specification: 320µA
• Identical operating temperature range: 0°C ~ 125°C
• Surface mount mounting type
• Equivalent or superior RoHS and MSL compliance

The LP2996MR/NOPB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction is product status: LP2996MR/NOPB maintains Active status, providing ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The LP2996MR/NOPB is the qualified substitute for the obsolete LP2996MR. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. The LP2996MR/NOPB maintains Active product status with documented inventory availability, supporting long-term supply chain requirements.

Selection between these parts is determined by availability and procurement timeline. For new designs or production requiring sustained component supply, the LP2996MR/NOPB is the appropriate choice. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can LP2996MR/NOPB be used as a direct replacement for LP2996MR?

A: Yes. Both components are identical in electrical performance, package configuration, and thermal characteristics. The "/NOPB" designation indicates lead-free plating and does not affect functional compatibility.

Q: What does the Obsolete status mean for LP2996MR?

A: Obsolete status indicates Texas Instruments has discontinued active production and support. The LP2996MR/NOPB, with Active status, represents the current equivalent available through authorized distribution channels.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the 8-PowerSOIC package with identical pinout and thermal pad configuration. PCB layouts and assembly processes require no modification.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" suffix denotes "No Plumbum" (lead-free) termination. This reflects RoHS3 compliance and does not alter electrical or mechanical performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both LP2996MR and LP2996MR/NOPB operate across 0°C to 125°C, supporting identical thermal specifications for DDR termination applications.
