Substitute Part Grouping Explanation

Substitution eligibility for the AF0603DR-072K2L is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±0.5%
• Power rating: 0.1W (1/10W)
• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS and environmental compliance: ROHS3 Compliant, MSL 1

The RC0603DR-072K2L meets all electrical and mechanical equivalence criteria. The primary difference is the feature set: the AF series includes anti-sulfur and AEC-Q200 automotive qualification, while the RC series features moisture-resistant construction. Both maintain identical core electrical specifications and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both AF0603DR-072K2L and RC0603DR-072K2L are active production components with full ROHS3 compliance and MSL 1 rating. Selection between these parts depends on application-specific environmental requirements:

The AF0603DR-072K2L is specified for automotive applications requiring AEC-Q200 qualification and anti-sulfur protection. This part is appropriate for designs with explicit automotive grade requirements or sulfur-rich environments.

The RC0603DR-072K2L provides moisture-resistant construction and is suitable for applications prioritizing humidity protection. This part offers significantly higher inventory availability (3062 units versus 786 units), which may be relevant for supply chain considerations.

Both parts are electrically and mechanically interchangeable within the specified parameter ranges. Selection should be based on environmental exposure conditions and regulatory requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Are AF0603DR-072K2L and RC0603DR-072K2L electrically identical?

A: Yes. Both parts have identical resistance (2.2 kOhms), tolerance (±0.5%), power rating (0.1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). They are electrically equivalent.

Q: Can RC0603DR-072K2L replace AF0603DR-072K2L in automotive applications?

A: RC0603DR-072K2L meets all electrical and mechanical specifications. However, it lacks AEC-Q200 automotive qualification and anti-sulfur features present in the AF series. Application requirements determine suitability.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0603 (1608 Metric) package with identical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm).

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection addresses corrosion from sulfur-containing environments, typically in automotive applications. Moisture-resistant construction protects against humidity and condensation. These address different environmental stressors.

Q: Are both parts RoHS compliant?

A: Yes. Both AF0603DR-072K2L and RC0603DR-072K2L are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
