LP2995MRX Equivalent & Substitute Parts

Part Overview

The LP2995MRX is a DDR Terminator PMIC in 8-SO PowerPad packaging manufactured by Texas Instruments. This integrated circuit regulates termination voltage for DDR memory applications, operating across a 2.2V to 5.5V supply range with 250µA supply current. The LP2995MRX is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the LP2995MRX is determined by strict equivalence across the following parameters:

• Identical functional application (DDR Terminator)
• Matching voltage supply range (2.2V ~ 5.5V)
• Equivalent current supply specification (250µA)
• Identical operating temperature range (0°C ~ 125°C)
• Same package and pinout (8-PowerSOIC, 0.154", 3.90mm Width)
• Surface mount compatibility
• Equivalent moisture sensitivity rating (MSL 3)

The LP2995MRX/NOPB qualifies as a direct substitute based on full alignment with all electrical and mechanical parameters. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The LP2995MRX/NOPB is the direct functional equivalent for the obsolete LP2995MRX. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility in DDR terminator applications.

Selection between these parts should be based on:

• Product availability: LP2995MRX is obsolete; LP2995MRX/NOPB maintains active status with current manufacturing support
• Regulatory compliance: LP2995MRX/NOPB meets ROHS3 compliance requirements, while the original LP2995MRX does not
• Environmental standards: Both parts maintain REACH Unaffected status
• Supply chain continuity: LP2995MRX/NOPB offers packaging flexibility through Cut Tape and Digi-Reel options

For new designs or system refreshes, LP2995MRX/NOPB is the appropriate selection. For legacy system maintenance where original part specifications are mandated, LP2995MRX remains available in limited inventory.

Frequently Asked Questions (FAQ)

Q: Can LP2995MRX/NOPB replace LP2995MRX in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The LP2995MRX/NOPB operates within the same voltage range (2.2V ~ 5.5V), current specification (250µA), temperature range (0°C ~ 125°C), and uses the identical 8-PowerSOIC package. Pin-for-pin substitution is direct.

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

A: The /NOPB designation indicates lead-free (no-lead) and RoHS3 compliant manufacturing. This reflects modern environmental and regulatory standards. The electrical and functional performance remains identical to the base LP2995MRX.

Q: Are there packaging differences between these parts?

A: The LP2995MRX/NOPB offers expanded packaging options including Cut Tape (CT) and Digi-Reel formats, providing supply chain flexibility. Both parts use the same 8-PowerSOIC physical package for PCB mounting.

Q: Why is the original LP2995MRX classified as obsolete?

A: Product obsolescence reflects Texas Instruments' transition to RoHS3 compliant manufacturing. The LP2995MRX/NOPB represents the current production equivalent with identical functionality and improved regulatory compliance.

Q: Are there any thermal or performance differences?

A: No. Both parts maintain identical operating temperature specifications (0°C ~ 125°C) and current supply characteristics (250µA). Thermal performance and electrical behavior are equivalent.

Q: What is the moisture sensitivity implication for storage and handling?

A: Both parts carry MSL 3 rating (168 Hours), indicating identical moisture sensitivity requirements. Standard ESD and moisture control procedures apply equally to both variants.
