Substitute Part Grouping Explanation

Substitute parts for the XC9502B095DR-G are identified based on strict parametric equivalence within the XC9502 series. The substitution criteria are defined by the following key parameters that must remain constant:

• Series and Base Product Number: XC9502
• Topology: Buck, Boost (dual-channel step-up/step-down)
• Number of Outputs: 2 channels
• Output Phases: 2
• Output Configuration: Positive
• Output Type: PWM Signal
• Supply Voltage Range: 2V ~ 10V
• Duty Cycle (Max): 80%
• Package / Case: 10-UFDFN Exposed Pad
• Supplier Device Package: 10-USP (2.7x2.5)
• Operating Temperature: -40°C ~ 85°C
• Control Features: Enable
• Synchronous Rectifier: No
• Clock Sync: No
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variations in switching frequency and packaging format (Tape & Reel versus Cut Tape & Digi-Reel) do not affect functional equivalence when all core electrical and mechanical parameters remain aligned.

Parameter Comparison

Engineering Selection Recommendations

The XC9502B092DR-G is a parametrically equivalent substitute for the XC9502B095DR-G. Both devices are manufactured by Torex Semiconductor Ltd within the active XC9502 series and share identical electrical specifications, package geometry, and compliance certifications.

Functional Equivalence: Both parts deliver identical 2-channel buck-boost DC-DC controller functionality with PWM output, 2V to 10V supply voltage operation, and 80% maximum duty cycle across the full -40°C to 85°C operating temperature range.

Mechanical Compatibility: Both parts use the 10-UFDFN exposed pad package with 10-USP (2.7x2.5) dimensions, ensuring direct PCB footprint compatibility and identical mounting procedures.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating, meeting identical environmental and regulatory requirements.

Differentiation: The primary difference is switching frequency (500kHz versus 180kHz) and packaging delivery format (Tape & Reel versus Cut Tape & Digi-Reel). The frequency difference does not affect functional equivalence but may influence external component selection (inductor and capacitor values) in the power stage design.

Supply Chain Consideration: The XC9502B092DR-G maintains higher inventory availability (799 pcs) compared to the main part (789 pcs), supporting procurement flexibility and lead-time optimization.

Frequently Asked Questions (FAQ)

Q1: Can XC9502B092DR-G replace XC9502B095DR-G in existing designs without PCB modification?

A: Yes. Both parts share identical 10-UFDFN exposed pad package geometry (10-USP 2.7x2.5 dimensions), ensuring direct footprint compatibility. No PCB layout changes are required for mechanical or electrical integration.

Q2: What is the impact of the 500kHz versus 180kHz switching frequency difference?

A: Switching frequency affects external component selection in the power stage. The 500kHz main part requires smaller inductors and capacitors compared to the 180kHz substitute. Designs must be re-evaluated for the substitute's lower frequency to ensure proper filtering and transient response. This is a design consideration, not a compatibility issue.

Q3: Are both parts suitable for the same operating temperature range?

A: Yes. Both XC9502B095DR-G and XC9502B092DR-G operate across -40°C to 85°C, meeting identical thermal specifications for industrial and consumer applications.

Q4: Do packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) affect component performance?

A: No. Packaging format differences relate only to supply and handling logistics. The actual component performance, electrical characteristics, and physical package dimensions remain identical. Format selection depends on assembly process requirements and procurement preferences.

Q5: Are both parts RoHS3 compliant?

A: Yes. Both XC9502B095DR-G and XC9502B092DR-G are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating and REACH unaffected status, meeting identical environmental compliance requirements.

Q6: What is the basis for substitution equivalence between these two parts?

A: Substitution equivalence is based on identical series designation (XC9502), matching topology (2-channel buck-boost), identical supply voltage range (2V ~ 10V), matching output configuration (positive PWM), identical package type (10-UFDFN), and aligned regulatory certifications. The parts are functionally interchangeable within the XC9502 controller family.

Q7: Can I use XC9502B092DR-G if my design specifies XC9502B095DR-G?

A: Functional substitution is possible with design review. The lower switching frequency (180kHz) requires re-evaluation of external inductor and capacitor values to maintain proper filtering and transient response. Electrical performance remains equivalent; external component optimization is necessary.
