Key Parameters

Substitute Part Grouping Explanation

The X9315WMIZ qualifies as a parametric equivalent to the X9313WMIZ based on the following critical substitution criteria:

Matching Parameters (Substitution Basis):

• Resistance value: 10kΩ
• Number of taps: 32
• Number of circuits: 1
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Mounting type: Surface Mount
• Package designation: 8-MSOP
• Operating temperature range: -40°C ~ 85°C
• Tolerance: ±20%
• Temperature coefficient: ±300ppm/°C
• Compliance certifications: ROHS3, REACH Unaffected

Differing Parameter:

• Resistance - Wiper (Ohms): X9313WMIZ = 40Ω (typical); X9315WMIZ = 200Ω (typical)

The wiper resistance difference does not preclude substitution in applications where wiper impedance is not a critical design constraint. Both parts share identical functional architecture, control interface, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the X9313WMIZ and X9315WMIZ maintain active production status with full ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for current and future applications. The X9315WMIZ offers significantly higher inventory availability (5800 pcs versus 803 pcs), providing supply chain advantages for high-volume production scenarios.

Selection between these parts depends on wiper resistance tolerance requirements. The X9313WMIZ with 40Ω typical wiper resistance is suitable for applications requiring lower output impedance or minimal loading effects on external circuits. The X9315WMIZ with 200Ω typical wiper resistance is appropriate for applications where higher wiper impedance is acceptable or beneficial for noise reduction.

Both parts share identical electrical specifications for potentiometer function, control interface, memory retention, and environmental performance across the -40°C to 85°C operating range. Pinout compatibility and package footprint are identical, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can X9315WMIZ directly replace X9313WMIZ on existing PCBs?

A: Yes. Both parts use identical 8-MSOP package geometry and pinout configuration. No PCB layout changes are required for physical substitution.

Q: What is the significance of the wiper resistance difference?

A: Wiper resistance affects the output impedance when the potentiometer is used as a voltage divider or signal source. The X9313WMIZ (40Ω) presents lower impedance to external circuits, while the X9315WMIZ (200Ω) presents higher impedance. Selection depends on whether your circuit design accounts for this loading effect.

Q: Are both parts suitable for 5V supply applications?

A: Yes. Both the X9313WMIZ and X9315WMIZ are rated for 5V supply voltage operation across the full -40°C to 85°C temperature range.

Q: Do both parts support non-volatile memory?

A: Yes. Both parts feature non-volatile memory, preserving the last programmed resistance setting across power cycles.

Q: What is the control interface for both parts?

A: Both parts use identical Up/Down (U/D, INC, CS) interface protocol for resistance adjustment and tap selection.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 2, 1 Year) ratings.

Q: Which part should I select for new designs?

A: Selection is based on wiper resistance requirements and supply availability. For new designs, either part is acceptable provided your circuit design accounts for the respective wiper impedance characteristics.
