Substitute Part Grouping Explanation

Substitution eligibility for the DFNA1002DT1 is determined by the following critical parameters:

• Resistance Value: Must be 10kΩ
• Number of Resistors: Must be 4 elements
• Circuit Type: Must be Isolated
• Package / Case: Must be 8-VDFN Exposed Pad
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -55°C to 125°C
• Power Per Element: Must be 50mW minimum
• Tolerance: May be equal to or tighter than ±0.5%
• Temperature Coefficient: Must be ±25ppm/°C or better
• Product Status: Must be Active
• RoHS Compliance: Must be ROHS3 Compliant

The DFNA1002AT5 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters, with an improved tolerance specification of ±0.1%.

Engineering Selection Recommendations

The DFNA1002AT5 is a qualified substitute for the DFNA1002DT1 based on the following criteria:

• Both components maintain Active product status, ensuring continued manufacturer support and availability
• Both are ROHS3 compliant, meeting environmental and regulatory requirements
• Both carry identical ECCN (EAR99) and HTSUS classifications, maintaining export and tariff consistency
• The DFNA1002AT5 provides improved tolerance specification (±0.1% versus ±0.5%), which represents a performance enhancement without introducing incompatibility
• Mechanical compatibility is absolute: identical package dimensions, pin count, and mounting configuration ensure direct PCB-level substitution
• Electrical performance parameters are fully matched across resistance value, power rating, temperature coefficient, and operating range

Selection between these parts should be based on application tolerance requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can DFNA1002AT5 be used as a direct replacement for DFNA1002DT1 on existing PCBs?

A: Yes. Both components share identical package dimensions (4.00mm x 4.00mm), pin configuration (8-pin VDFN), and mounting type (surface mount). No PCB redesign is required.

Q: What is the primary difference between these two parts?

A: The DFNA1002AT5 features a tighter tolerance specification of ±0.1% compared to the DFNA1002DT1's ±0.5%. All other electrical and mechanical parameters are identical.

Q: Are there any thermal or operating condition differences?

A: No. Both components operate across the identical temperature range (-55°C to 125°C) with matching temperature coefficients (±25ppm/°C) and power ratings (50mW per element).

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant with MSL rating of 1 (Unlimited), identical ECCN classification (EAR99), and matching HTSUS codes (8533.21.0020).

Q: Which part should be selected for new designs?

A: Selection depends on application tolerance requirements. The DFNA1002AT5 is suitable when tighter tolerance specifications are beneficial. The DFNA1002DT1 remains appropriate for applications where ±0.5% tolerance is acceptable.
