AF0201FR-071K2L Equivalent & Substitute Parts

Part Overview

The AF0201FR-071K2L is a 1.2 kOhms ±1% thick film chip resistor in 0201 package (0.60mm x 0.30mm) rated at 0.05W (1/20W) power dissipation. Manufactured by YAGEO under the AF series, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for harsh automotive environments with operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance ratings are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the AF0201FR-071K2L is determined by strict equivalence across the following parameters:

• Resistance value: 1.2 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package type: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height - Seated (Max): 0.010" (0.26mm)
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts maintain these core electrical and mechanical specifications. Operating temperature range and specific feature sets (anti-sulfur, moisture resistant, automotive ratings) are noted as secondary differentiators but do not disqualify substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—AC0201FR-071K2L, CRCW02011K20FNED, and ERJ-1GNF1201C—meet the core electrical and mechanical requirements for direct substitution with the AF0201FR-071K2L. Selection among these alternatives should be based on:

Product Status & Availability: All parts are active in production with substantial inventory levels. AC0201FR-071K2L (YAGEO) offers 103,173 units in stock; ERJ-1GNF1201C (Panasonic) provides 181,377 units; CRCW02011K20FNED (Vishay Dale) has 52,077 units available.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. AC0201FR-071K2L and the original AF0201FR-071K2L both carry automotive AEC-Q200 qualification. CRCW02011K20FNED and ERJ-1GNF1201C do not list AEC-Q200 ratings in provided specifications.

Operating Temperature Range: AC0201FR-071K2L and CRCW02011K20FNED extend to -55°C ~ 155°C, providing 30°C additional upper temperature margin compared to AF0201FR-071K2L and ERJ-1GNF1201C (-55°C ~ 125°C). This difference is relevant only for applications requiring operation above 125°C.

Feature Differentiation: AF0201FR-071K2L includes anti-sulfur coating; AC0201FR-071K2L adds moisture resistant properties. CRCW02011K20FNED and ERJ-1GNF1201C list no special features in provided data.

Frequently Asked Questions (FAQ)

Q: Can AC0201FR-071K2L replace AF0201FR-071K2L in all applications?

A: Yes, for applications operating within -55°C to 125°C. AC0201FR-071K2L maintains identical electrical specifications (1.2 kOhms ±1%, 0.05W, ±200ppm/°C) and physical dimensions (0201 package, 0.60mm x 0.30mm). Both carry ROHS3 compliance and MSL 1 rating. AC0201FR-071K2L extends upper operating temperature to 155°C and adds moisture resistant properties, making it suitable for the same applications and additional high-temperature environments.

Q: What is the difference between YAGEO AF and AC series resistors?

A: Both AF0201FR-071K2L and AC0201FR-071K2L are YAGEO 0201 thick film resistors with identical electrical specifications. The AF series includes anti-sulfur coating; the AC series adds moisture resistant properties. Both are automotive AEC-Q200 qualified. Selection depends on environmental exposure requirements.

Q: Are Vishay Dale CRCW02011K20FNED and Panasonic ERJ-1GNF1201C suitable for automotive applications?

A: CRCW02011K20FNED and ERJ-1GNF1201C meet all core electrical and mechanical specifications for 0201 1.2 kOhms ±1% resistors. However, provided specifications do not list automotive AEC-Q200 qualification for these parts. If AEC-Q200 certification is a design requirement, AC0201FR-071K2L or AF0201FR-071K2L are the appropriate selections.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes. All four parts share identical 0201 package dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm), maximum seated height (0.010" / 0.26mm), and Tape & Reel (TR) packaging format. PCB footprints, pick-and-place machine settings, and reflow profiles remain unchanged across all substitutes.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All four parts carry this rating, eliminating moisture sensitivity as a selection constraint. Parts can be stored and handled under standard conditions without special desiccant packaging or pre-reflow baking procedures.

Q: How do temperature coefficients affect circuit performance?

A: All four parts specify ±200ppm/°C temperature coefficient. This means resistance value changes by approximately 0.02% per degree Celsius across the operating temperature range. For precision analog circuits, this specification is identical across all substitutes and does not differentiate selection.
