Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IP4253CZ8-4-TTL,13 is determined by the following critical parameters:

• Package / Case: Must be 8-UFDFN Exposed Pad to ensure PCB footprint compatibility
• Physical Dimensions: Must match 0.067" L x 0.053" W (1.70 mm x 1.35 mm) and 0.022" (0.55 mm) height
• Number of Channels: Must be 4 channels
• Filter Technology: Must be RC (Pi) topology, 2nd order low-pass
• Operating Temperature Range: Must support -40°C ~ 85°C
• ESD Protection: Must include ESD protection capability
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The IP4254CZ8-4-TTL,13 qualifies as a substitute based on matching all physical, electrical topology, and compliance parameters. The primary difference is the resistance value (100 Ohms versus 200 Ohms), which results in different attenuation characteristics but maintains functional compatibility within the same product family and package specification.

Parameter Comparison

Engineering Selection Recommendations

The IP4254CZ8-4-TTL,13 is the active equivalent for the obsolete IP4253CZ8-4-TTL,13. Both components share identical package specifications, physical dimensions, channel configuration, and compliance certifications (ROHS3, MSL 1). The substitute maintains full PCB compatibility and thermal operating range.

The primary electrical difference is the channel resistance value: 100 Ohms (IP4254) versus 200 Ohms (IP4253), resulting in 5 dB lower attenuation at the specified frequency range (28 dB versus 33 dB @ 800 MHz ~ 3 GHz). This difference must be evaluated against system EMI filtering requirements. The IP4254CZ8-4-TTL,13 is currently in active production with established supply chain availability, making it the recommended replacement for discontinued designs.

Frequently Asked Questions (FAQ)

Q: Can the IP4254CZ8-4-TTL,13 be used as a direct drop-in replacement for the IP4253CZ8-4-TTL,13?

A: Yes, from a physical and mechanical standpoint. Both components use the identical 8-UFDFN exposed pad package with matching dimensions (0.067" L x 0.053" W, 0.022" height) and PCB footprint. Electrical performance differs due to the 100 Ohm versus 200 Ohm channel resistance specification.

Q: What is the impact of the resistance difference on filter performance?

A: The lower resistance value (100 Ohms) in the IP4254 results in reduced attenuation of 5 dB across the 800 MHz to 3 GHz frequency range compared to the IP4253. System-level EMI filtering requirements must be evaluated to determine if this performance difference is acceptable for your application.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the IP4253CZ8-4-TTL,13 and IP4254CZ8-4-TTL,13 are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) ratings. Both support the full -40°C to 85°C operating temperature range.

Q: What is the supply status difference between these parts?

A: The IP4253CZ8-4-TTL,13 is obsolete and no longer manufactured. The IP4254CZ8-4-TTL,13 is in active production status with current inventory availability, ensuring long-term supply chain continuity.

Q: Are there packaging format differences?

A: The IP4254CZ8-4-TTL,13 is supplied in Tape & Reel (TR) format. Confirm packaging requirements for your manufacturing process, as this may differ from the original part's packaging specification.
