Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEMI2STD/LP,115 is determined by the following critical parameters:

• Filter Architecture: 2nd order RC (Pi) topology with 2 channels
• Package Compatibility: SOT-665 surface mount package with identical footprint dimensions (1.60mm × 1.20mm × 0.60mm)
• Electrical Characteristics: Resistance and capacitance values within acceptable tolerance for EMI filtering applications
• Environmental Compliance: RoHS3 compliance, MSL 1 rating, and operating temperature range -40°C to +85°C
• ESD Protection: Integrated ESD protection capability

The IP4256CZ5-W,115 manufactured by Nexperia USA Inc. qualifies as a substitute based on matching filter topology, package type, physical dimensions, environmental specifications, and compliance certifications. Variations in resistance (100 Ohms vs. 65 Ohms) and capacitance (19 pF vs. 18.5 pF) reflect design optimization for different frequency response characteristics while maintaining the same functional filter class.

Engineering Selection Recommendations

The IP4256CZ5-W,115 is the designated substitute for the obsolete PEMI2STD/LP,115 based on the following engineering criteria:

• Package Compatibility: Both components use the SOT-665 package with identical physical dimensions, ensuring direct PCB footprint compatibility without layout modifications.
• Functional Equivalence: Both filters implement 2nd order RC (Pi) topology with 2 channels, maintaining the same filtering architecture and ESD protection capability.
• Compliance Alignment: Both parts meet ROHS3 compliance requirements, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring equivalent environmental and regulatory performance.
• Active Product Status: The IP4256CZ5-W,115 is currently in active production with confirmed inventory availability (946 pcs), providing long-term supply continuity compared to the obsolete PEMI2STD/LP,115.
• Temperature Performance: Identical operating temperature range (-40°C to +85°C) ensures equivalent thermal performance across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the IP4256CZ5-W,115 be used as a direct replacement for the PEMI2STD/LP,115 without PCB modifications?

A: Yes. Both components use the SOT-665 package with identical dimensions (1.60mm × 1.20mm × 0.60mm), enabling direct footprint compatibility without PCB layout changes.

Q: What is the difference between the 65 Ohm and 100 Ohm resistance values?

A: The resistance value affects the filter's cutoff frequency and attenuation characteristics. The PEMI2STD/LP,115 uses 65 Ohms while the IP4256CZ5-W,115 uses 100 Ohms. These values are optimized for different application requirements within the RC (Pi) filter topology.

Q: Are both parts RoHS compliant?

A: Yes. Both the PEMI2STD/LP,115 and IP4256CZ5-W,115 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the MSL rating for these components?

A: Both components have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the IP4256CZ5-W,115 available in the same packaging format?

A: The IP4256CZ5-W,115 is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing standard component distribution options for production environments.

Q: Do both filters provide ESD protection?

A: Yes. Both the PEMI2STD/LP,115 and IP4256CZ5-W,115 include integrated ESD protection, ensuring equivalent electrostatic discharge performance.
