Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9313US-3T2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ (exact match required)
• Number of taps: 32 (exact match required)
• Interface protocol: Up/Down (U/D, INC, CS) (exact match required)
• Memory type: Non-Volatile (exact match required)
• Supply voltage range: 3V ~ 5.5V (exact match required)
• Package type: 8-SOIC (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: ±300ppm/°C (exact match required)

The X9313USZ-3T1 meets all substitution criteria as a direct functional equivalent across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The X9313USZ-3T1 manufactured by Intersil is a direct functional substitute for the obsolete X9313US-3T2. Both devices are electrically and mechanically identical across all specified parameters. The primary distinction is product status: the X9313USZ-3T1 maintains active production status with confirmed inventory availability (5611 pcs), whereas the X9313US-3T2 is classified as obsolete with limited remaining stock (799 pcs).

For new designs and ongoing system support requiring 50kΩ digital potentiometer functionality with 32-tap resolution and Up/Down interface control, the X9313USZ-3T1 is the appropriate selection. Pin-to-pin compatibility and identical electrical characteristics ensure direct replacement capability in existing PCB layouts without design modification.

Frequently Asked Questions (FAQ)

Q: Can the X9313USZ-3T1 replace the X9313US-3T2 in existing designs?

A: Yes. The X9313USZ-3T1 is a direct pin-to-pin and functional equivalent. All electrical parameters, package dimensions, and interface specifications are identical. No PCB layout or firmware modifications are required.

Q: What are the key differences between these parts?

A: The primary difference is manufacturer (Renesas vs. Intersil) and product status (Obsolete vs. Active). All functional and electrical specifications are identical.

Q: Are there any compatibility concerns with the 8-SOIC package?

A: No. Both parts use the identical 8-SOIC package with 0.154" width and 3.90mm dimensions. Footprint compatibility is guaranteed.

Q: Does the X9313USZ-3T1 support the same supply voltage range?

A: Yes. Both parts operate across the identical 3V to 5.5V supply voltage range with the same temperature coefficient and tolerance specifications.

Q: Why is the X9313US-3T2 classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The X9313USZ-3T1 provides continued availability for this functionality.
