Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT5113LI-01-G is determined by the following critical parameters:

• Resistance value: 1k Ohm (exact match required)
• Number of taps: 100 (exact match required)
• Interface type: Up/Down (U/D, INC, CS) (exact match required)
• Memory type: Non-Volatile (exact match required)
• Supply voltage range: 2.5V ~ 6V (must be compatible)
• Operating temperature range: -40°C ~ 85°C (must be compatible)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: 300ppm/°C (exact match required)

The primary substitute identified is CAT5113VI-01-GT3, which maintains identical electrical specifications while differing only in mounting technology (Surface Mount vs. Through Hole) and packaging format (Cut Tape vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both the CAT5113LI-01-G and CAT5113VI-01-GT3 are obsolete products from onsemi. Selection between these parts depends on circuit board design requirements:

The CAT5113LI-01-G is suitable for through-hole PCB designs utilizing 8-DIP footprints. The CAT5113VI-01-GT3 is suitable for surface-mount PCB designs utilizing 8-SOIC footprints. Both parts maintain identical electrical performance across all specified parameters, including supply voltage, operating temperature range, resistance value, tap count, and interface protocol.

The CAT5113VI-01-GT3 carries RoHS3 compliance certification, whereas compliance status for the CAT5113LI-01-G is not specified in available documentation. Both parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can CAT5113VI-01-GT3 replace CAT5113LI-01-G in an existing design?

A: Electrical substitution is possible only if the PCB design accommodates surface-mount 8-SOIC packaging. Through-hole 8-DIP designs cannot directly accept the surface-mount variant without PCB redesign.

Q: What are the key differences between these parts?

A: The parts are electrically identical. The primary differences are mounting technology (through-hole vs. surface-mount) and package footprint (8-DIP vs. 8-SOIC). Packaging format is Cut Tape (CT) for CAT5113VI-01-GT3.

Q: Are there compatibility concerns with the interface protocol?

A: No. Both parts implement identical Up/Down (U/D, INC, CS) interface protocols and non-volatile memory architecture, ensuring direct functional compatibility at the circuit level when package constraints are satisfied.

Q: What is the significance of the obsolete product status?

A: Both parts are obsolete, indicating onsemi has discontinued production. Procurement should prioritize available inventory. The CAT5113VI-01-GT3 shows higher inventory availability (5087 Pcs) compared to CAT5113LI-01-G (930 Pcs).

Q: Are there compliance differences between the two parts?

A: The CAT5113VI-01-GT3 is certified RoHS3 Compliant. Compliance certification for CAT5113LI-01-G is not documented. Both parts are REACH Unaffected and classified as EAR99.
