Key Parameters

Substitute Part Grouping Explanation

Substitution of the X9313ZST2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1kΩ
• Number of taps: 32
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Package type: 8-SOIC
• Mounting configuration: Surface Mount
• Operating temperature range: 0°C ~ 70°C
• Tolerance: ±20%
• Temperature coefficient: ±300ppm/°C

The X9313ZSZT1 meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete X9313ZST2.

Parameter Comparison

Engineering Selection Recommendations

The X9313ZSZT1 is the direct equivalent for the obsolete X9313ZST2. Selection of the X9313ZSZT1 is based on:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance, providing regulatory advantage over the non-compliant X9313ZST2
• Availability in Cut Tape (CT) and Digi-Reel® packaging options, supporting both prototype and production workflows
• Identical interface protocol and pin configuration enabling direct PCB-level replacement without design modification

Frequently Asked Questions (FAQ)

Q: Can the X9313ZSZT1 be used as a direct replacement for the X9313ZST2 on existing PCBs?

A: Yes. The X9313ZSZT1 is electrically and mechanically identical to the X9313ZST2 across all functional parameters, including resistance value, tap count, interface protocol, supply voltage, and package dimensions. No PCB redesign is required.

Q: What is the primary reason for substituting the X9313ZST2?

A: The X9313ZST2 is classified as obsolete. The X9313ZSZT1 is an active product from the same manufacturer with identical specifications, ensuring continued component availability for new designs and production runs.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The X9313ZST2 is RoHS non-compliant, while the X9313ZSZT1 is ROHS3 compliant. For applications subject to RoHS regulations, the X9313ZSZT1 is the required choice.

Q: What packaging options are available for the X9313ZSZT1?

A: The X9313ZSZT1 is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both small-quantity prototype applications and high-volume production requirements.

Q: Are the pin configurations identical between X9313ZST2 and X9313ZSZT1?

A: Yes. Both parts use the 8-SOIC package with identical pin assignments and interface protocol (Up/Down, INC, CS), enabling direct functional substitution.

Q: Is there any difference in operating temperature range?

A: No. Both parts operate across the identical temperature range of 0°C to 70°C.
