Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PEMI2STD/HT,115 is determined by the following critical parameters:

• Filter technology and order (2nd order RC (Pi) topology)
• Number of channels (2-channel configuration)
• Package type (SOT-665 surface mount)
• Physical dimensions (1.60 mm × 1.20 mm × 0.60 mm)
• ESD protection capability
• Operating temperature range (-40°C to 85°C)
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

The IP4256CZ5-W,115 qualifies as a substitute based on matching filter topology, channel count, package type, physical dimensions, ESD protection, operating temperature range, and regulatory compliance. Variations in resistance and capacitance values represent design trade-offs for different application requirements while maintaining functional compatibility within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The IP4256CZ5-W,115 is available as an active product from the same manufacturer, providing supply chain continuity for applications currently using the obsolete PEMI2STD/HT,115. Both components maintain identical compliance certifications (RoHS3, REACH Unaffected, EAR99) and share the same physical footprint and package type.

Selection between these components should be based on application-specific filtering requirements. The PEMI2STD/HT,115 configuration (45 Ohms, 23 pF) and the IP4256CZ5-W,115 configuration (100 Ohms, 19 pF) produce different frequency response characteristics. The IP4256CZ5-W,115 provides 20 dB attenuation across the 800 MHz to 3 GHz frequency band and is specified for LAN and WAN applications.

Frequently Asked Questions (FAQ)

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

A: Both components share identical package type (SOT-665), physical dimensions, channel count (2), filter topology (2nd order RC Pi), ESD protection, operating temperature range, and regulatory compliance. The primary difference is the resistance and capacitance values, which affect filtering characteristics. Substitution is mechanically and electrically compatible at the package level; however, circuit performance will differ due to the different RC values.

Q: What are the key differences between these two filters?

A: The PEMI2STD/HT,115 uses 45 Ohm resistance with 23 pF total capacitance, while the IP4256CZ5-W,115 uses 100 Ohm resistance with 19 pF total capacitance. These differences result in different cutoff frequencies and attenuation profiles. The IP4256CZ5-W,115 is specified for LAN and WAN applications with 20 dB attenuation in the 800 MHz to 3 GHz range.

Q: Are both components RoHS compliant?

A: Yes, both the PEMI2STD/HT,115 and IP4256CZ5-W,115 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both components have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these components available in different packaging options?

A: The PEMI2STD/HT,115 is specified with standard packaging. The IP4256CZ5-W,115 is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement and assembly workflows.
