Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCH7900VTT/C0L,112 is determined by the following critical parameters:

• Manufacturer: NXP USA Inc. (same manufacturer ensures design continuity)
• Base Product Number: PCH7900 (core functional platform)
• Package Type: 16-pin TSSOP surface mount (mechanical and electrical interface compatibility)
• Functional Description: IC FRACTIONAL NPLL (identical circuit function)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification (regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The substitute part PCH7900VTT/C0L,118 shares all these critical parameters, differing only in packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The PCH7900VTT/C0L,118 is a direct functional equivalent to the PCH7900VTT/C0L,112. Selection between these parts should be based on the following factors:

Product Status: The PCH7900VTT/C0L,118 maintains Active status with NXP USA Inc., ensuring ongoing availability and manufacturing support. The PCH7900VTT/C0L,112 is classified as Obsolete, limiting future procurement options.

Regulatory Compliance: Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99), ensuring no regulatory barriers to substitution.

Packaging Considerations: The PCH7900VTT/C0L,118 is supplied in Tape & Reel format, which is standard for high-volume production environments. The PCH7900VTT/C0L,112 uses standard packaging. Tape & Reel packaging is compatible with automated assembly equipment and does not affect component electrical or mechanical performance.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) rating, indicating identical handling and storage requirements.

For new designs and ongoing production, the PCH7900VTT/C0L,118 is the recommended selection due to active product status and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are PCH7900VTT/C0L,112 and PCH7900VTT/C0L,118 electrically identical?

A: Yes. Both parts are fractional NPLL integrated circuits with identical functional descriptions, base product numbers, and compliance certifications. The difference in part number suffix reflects packaging format and product lifecycle status, not electrical performance.

Q: What is the difference between standard packaging and Tape & Reel (TR) packaging?

A: Tape & Reel packaging is a continuous strip format designed for automated pick-and-place assembly equipment. Standard packaging typically refers to individual or bulk quantities. Both formats contain identical components with no electrical or mechanical differences. Tape & Reel is preferred for high-volume manufacturing.

Q: Can I use PCH7900VTT/C0L,118 as a direct replacement in existing assemblies?

A: Yes. The 16-pin TSSOP surface mount package, pin configuration, and electrical specifications are identical. No PCB layout or design modifications are required.

Q: Why is the PCH7900VTT/C0L,112 marked as Obsolete?

A: Obsolete status indicates that NXP USA Inc. has discontinued active manufacturing and support for this specific part number variant. The active equivalent PCH7900VTT/C0L,118 provides continued access to the same core functionality.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Moisture Sensitivity Level (MSL 1 - Unlimited) is also identical, ensuring equivalent handling and storage requirements.

Q: What inventory considerations should I account for when transitioning from PCH7900VTT/C0L,112 to PCH7900VTT/C0L,118?

A: The PCH7900VTT/C0L,118 has 1046 units in stock (Active status), while PCH7900VTT/C0L,112 has 935 units (Obsolete status). For ongoing production, the active part number ensures sustained availability.
