Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9511WSIT2 is determined by strict equivalence across the following critical parameters: resistance value (10kΩ), number of taps (32), circuit configuration (1 circuit), interface type (pushbutton), memory type (non-volatile), supply voltage (5V), taper characteristic (linear), package type (8-SOIC), and operating temperature range (-40°C ~ 85°C). All identified substitutes maintain identical electrical and mechanical specifications across these parameters, ensuring functional compatibility within the original design constraints.

The substitute parts are grouped as follows:

Direct Manufacturer Substitute: X9511WSIZ — Active product status with identical parametric specifications and ROHS3 compliance.

Parametric Equivalent: X9511WSIZT1 — Active product status with identical parametric specifications and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both X9511WSIZ and X9511WSIZT1 are functionally equivalent substitutes for the obsolete X9511WSIT2. The primary distinction between the substitutes and the original part is product status: both alternatives are active components with current manufacturing support from Renesas Electronics Corporation.

A secondary consideration is regulatory compliance. The X9511WSIT2 is RoHS non-compliant, while both substitute parts (X9511WSIZ and X9511WSIZT1) are ROHS3 compliant. This compliance improvement aligns with current environmental and regulatory requirements for electronic component procurement.

All three parts share identical electrical characteristics, mechanical specifications, and environmental ratings. Selection between X9511WSIZ and X9511WSIZT1 may be determined by packaging availability and inventory considerations, as both parts are functionally interchangeable within the original design.

Frequently Asked Questions (FAQ)

Q: Can X9511WSIZ and X9511WSIZT1 be used interchangeably with X9511WSIT2?

A: Yes. Both substitute parts maintain identical parametric specifications across all critical electrical and mechanical parameters, including resistance value, tap configuration, interface type, supply voltage, package type, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the primary reason for seeking substitutes for X9511WSIT2?

A: The X9511WSIT2 is classified as obsolete. Active alternatives ensure continued component availability for production, maintenance, and field replacement applications.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The X9511WSIT2 is RoHS non-compliant, while X9511WSIZ and X9511WSIZT1 are both ROHS3 compliant. This represents an improvement in regulatory alignment for new designs and procurement.

Q: Do the substitute parts require any PCB layout or schematic modifications?

A: No. Both substitute parts are housed in the same 8-SOIC package with identical pinout and electrical interface specifications. No design changes are required.

Q: What is the difference between X9511WSIZ and X9511WSIZT1?

A: Both parts are parametrically identical. The primary difference is packaging format: X9511WSIZ is supplied in tube packaging, while X9511WSIZT1 packaging is not specified in the provided data. Selection may depend on procurement requirements and inventory availability.

Q: Are the operating temperature ranges identical across all three parts?

A: Yes. All three parts operate across the -40°C ~ 85°C temperature range with identical temperature coefficient specifications (300ppm/°C).
