Substitute Part Grouping Explanation

Substitution eligibility for the AF0805DR-072K2L is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±0.5%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RC0805DR-072K2L meets all these criteria and qualifies as a direct substitute. Both parts maintain identical electrical performance specifications and physical dimensions, with differences limited to feature sets (anti-sulfur versus moisture resistant) that do not affect core functionality within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the AF0805DR-072K2L and RC0805DR-072K2L are active production components from YAGEO with ROHS3 compliance and MSL 1 rating. The primary distinction lies in feature differentiation: the AF series incorporates anti-sulfur properties with AEC-Q200 automotive qualification, while the RC series emphasizes moisture-resistant characteristics. Selection between these parts should be based on application environment requirements. For automotive applications requiring AEC-Q200 certification, the AF0805DR-072K2L is the specified choice. For general industrial or consumer applications where moisture resistance is prioritized, the RC0805DR-072K2L provides equivalent electrical performance. Both parts are suitable for PCB assembly in standard reflow processes and maintain identical thermal and electrical behavior across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RC0805DR-072K2L be used as a direct replacement for AF0805DR-072K2L?

A: Yes. Both parts share identical electrical specifications (2.2 kOhms ±0.5%, 0.125W), physical dimensions (0805 package), and operating parameters (-55°C ~ 155°C). The functional difference is limited to environmental feature sets (anti-sulfur versus moisture resistant), which do not affect core resistive performance.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W, 0.024" max height) and two terminations. PCB footprints and assembly processes are fully compatible.

Q: What is the significance of AEC-Q200 qualification on the AF0805DR-072K2L?

A: AEC-Q200 is an automotive electronics qualification standard. The AF0805DR-072K2L meets this certification, making it suitable for automotive applications. The RC0805DR-072K2L does not carry this designation and should not be used in applications requiring explicit AEC-Q200 compliance.

Q: Do these parts have different moisture sensitivity requirements?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling. Moisture sensitivity level is equivalent between the two parts.

Q: Are there compliance or regulatory differences between these substitutes?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications. No regulatory barriers exist for substitution.
