Substitute Part Grouping Explanation

Substitution eligibility for the DFNA1002FT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Power per element: 50mW (exact match required)
• Package / Case: 8-VDFN Exposed Pad (exact match required)
• Supplier device package: 8-DFN (4x4) (exact match required)
• Physical dimensions: 4.00mm x 4.00mm, 0.95mm max height (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The DFNA1002AT5 qualifies as a substitute because it maintains all critical electrical and mechanical parameters. The tolerance specification differs (±0.1% versus ±1%), representing an upgrade in precision that does not compromise compatibility or functionality in applications designed for the DFNA1002FT1.

Parameter Comparison

Engineering Selection Recommendations

Both the DFNA1002FT1 and DFNA1002AT5 are active production components with ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions. The DFNA1002AT5 provides improved tolerance specification (±0.1% versus ±1%) while maintaining identical electrical performance across all other parameters. Selection between these parts depends on application tolerance requirements: the DFNA1002FT1 is appropriate for general-purpose applications, while the DFNA1002AT5 is suitable for applications requiring tighter resistor value control. Both parts are pin-compatible and footprint-compatible for direct substitution on PCB assemblies.

Frequently Asked Questions (FAQ)

Q: Can the DFNA1002AT5 be used as a direct replacement for the DFNA1002FT1?

A: Yes. Both parts share identical package specifications (8-VDFN Exposed Pad, 8-DFN 4x4), physical dimensions (4.00mm x 4.00mm, 0.95mm height), pin count (8), and electrical performance parameters including resistance value, power rating, temperature coefficient, and operating temperature range. The DFNA1002AT5 features improved tolerance (±0.1% versus ±1%), which does not prevent substitution.

Q: What are the key differences between DFNA1002FT1 and DFNA1002AT5?

A: The primary difference is tolerance specification. The DFNA1002FT1 has ±1% tolerance, while the DFNA1002AT5 has ±0.1% tolerance. All other electrical and mechanical parameters are identical.

Q: Are there any PCB layout or assembly considerations when substituting these parts?

A: No. Both parts use the same 8-VDFN Exposed Pad package with identical footprint dimensions and pin assignments. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DFNA1002FT1 and DFNA1002AT5 are ROHS3 compliant with MSL Level 1 rating, confirming equivalent environmental and regulatory compliance.

Q: Which part should be selected for precision-critical applications?

A: The DFNA1002AT5 is appropriate for applications requiring tighter resistor value control due to its ±0.1% tolerance specification. The DFNA1002FT1 is suitable for applications where ±1% tolerance is acceptable.
