Key Parameters

Substitute Part Grouping Explanation

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

• Filter Configuration: 2nd order RC (Pi) topology with 2 channels
• Resistance Value: 100 Ohms per channel (fixed requirement)
• Package Type: SOT-665 surface mount package (physical and electrical compatibility)
• Operating Temperature: -40°C to 85°C range
• ESD Protection: Integrated protection required
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The IP4256CZ5-W,115 manufactured by Nexperia USA Inc. meets all substitution criteria. While the capacitance value differs (19 pF total versus 11 pF), both components maintain identical resistance, package, temperature range, and compliance specifications. The capacitance variance results in different frequency response characteristics but does not prevent functional substitution in applications where the filter's attenuation profile is compatible with system requirements.

Engineering Selection Recommendations

The IP4256CZ5-W,115 is the qualified substitute for the obsolete PEMI2STD/RG,115. Selection is based on the following engineering criteria:

• Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing and deployment environments.
• Active Product Status: The IP4256CZ5-W,115 is currently in active production with confirmed inventory availability (946 pieces), eliminating supply chain risk associated with the obsolete PEMI2STD/RG,115.
• Physical Compatibility: Identical SOT-665 package dimensions and surface mount configuration enable direct PCB layout compatibility without redesign.
• Electrical Compatibility: Matching 100 Ohm resistance per channel and identical operating temperature range (-40°C to 85°C) preserve circuit performance parameters.
• Functional Equivalence: Both components implement 2nd order RC (Pi) low pass filter topology with integrated ESD protection, maintaining the intended EMI filtering function for data line applications.

Frequently Asked Questions (FAQ)

Q: Can the IP4256CZ5-W,115 be used as a direct replacement for the PEMI2STD/RG,115?

A: Yes. Both components share identical package type (SOT-665), resistance value (100 Ohms per channel), operating temperature range (-40°C to 85°C), and filter topology (2nd order RC Pi). Physical and electrical compatibility is confirmed.

Q: What is the difference between the 11 pF and 19 pF capacitance values?

A: The capacitance difference affects the filter's frequency response and attenuation characteristics. The IP4256CZ5-W,115 with 19 pF provides 20 dB attenuation across the 800 MHz to 3 GHz frequency range. Application-specific frequency requirements determine whether this difference impacts system performance.

Q: Are both components available in the same packaging options?

A: The PEMI2STD/RG,115 is obsolete with no current production. The IP4256CZ5-W,115 is available in Cut Tape (CT) and Digi-Reel packaging formats with active inventory.

Q: Do both components meet the same compliance standards?

A: Yes. Both the PEMI2STD/RG,115 and IP4256CZ5-W,115 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and deployment.

Q: What applications are supported by the substitute part?

A: The IP4256CZ5-W,115 is specified for LAN and WAN applications. The original PEMI2STD/RG,115 was designed for data lines in mobile devices. Functional compatibility depends on application-specific frequency and attenuation requirements.
