Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Filter technology: RC (Pi) topology
• Filter order: 2nd order low pass
• Number of channels: 2
• Resistance value: 100 Ohms per channel
• Package type: SOT-665
• Physical dimensions: 1.60 mm × 1.20 mm × 0.60 mm
• Mounting type: Surface mount
• Operating temperature range: -40°C to 85°C minimum
• ESD protection: Present

Allowable Variation Parameters:

• Capacitance value: ±10% tolerance acceptable (18.5 pF ±1.85 pF range)
• Attenuation characteristics: May vary based on frequency response specifications
• Manufacturer: Different qualified manufacturers permitted
• Product status: Active status preferred for ongoing availability

The IP4256CZ5-W,115 manufactured by Nexperia USA Inc. meets all mandatory matching parameters and falls within the allowable capacitance variation range (19 pF vs. 18.5 pF).

Parameter Comparison

Engineering Selection Recommendations

The IP4256CZ5-W,115 is a qualified substitute for the PEMI2STD/RP,115 based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications requiring environmental compliance documentation.

Electrical Parameter Equivalence: The substitute part maintains identical resistance (100 Ohms per channel) and operating temperature specifications (-40°C to 85°C). The capacitance variation of 0.5 pF (19 pF vs. 18.5 pF) represents a 2.7% deviation, which remains within standard component tolerance ranges for RC filter applications.

Availability & Product Lifecycle: The IP4256CZ5-W,115 carries active product status with documented inventory availability (946 units), providing supply chain continuity compared to the obsolete PEMI2STD/RP,115.

Physical & Mechanical Compatibility: Identical SOT-665 package dimensions and surface mount configuration ensure direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical filter topology (RC Pi, 2nd order), channel configuration (2 channels), resistance value (100 Ohms), package type (SOT-665), and physical dimensions. The 0.5 pF capacitance difference (19 pF vs. 18.5 pF) falls within acceptable tolerance for this component category.

Q: What is the significance of the capacitance difference between these parts?

A: The capacitance variation of 0.5 pF represents a 2.7% deviation from the original specification. For RC (Pi) EMI filters operating in the data line filtering application space, this variance remains within standard component tolerance ranges and does not alter the fundamental filtering characteristics.

Q: Are there any packaging or handling differences between these parts?

A: Both parts use SOT-665 surface mount packaging with identical physical dimensions (1.60 mm × 1.20 mm × 0.60 mm). Both maintain Moisture Sensitivity Level 1 (unlimited shelf life). The IP4256CZ5-W,115 is available in Cut Tape and Digi-Reel packaging options.

Q: What compliance certifications apply to both parts?

A: Both the PEMI2STD/RP,115 and IP4256CZ5-W,115 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component applications.

Q: Why is the substitute part listed as active status while the original is obsolete?

A: The PEMI2STD/RP,115 has reached end-of-life status with NXP Semiconductors. The IP4256CZ5-W,115 from Nexperia USA Inc. provides equivalent functionality with active manufacturing and supply chain support, ensuring long-term component availability for ongoing production needs.
