Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-0741R2L is determined by strict equivalence across the following parameters:

• Resistance value: 41.2 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in operating temperature range, height dimensions, and manufacturer-specific features do not affect functional substitutability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and ROHS3 compliance. Selection between AC0201FR-0741R2L and its substitutes should be based on:

AC0201FR-0741R2L (YAGEO): Features AEC-Q200 automotive qualification and moisture-resistant construction. Supports full operating temperature range to 155°C. Recommended for automotive applications requiring explicit AEC-Q200 certification.

RC0201FR-0741R2L (YAGEO): Moisture-resistant variant without explicit AEC-Q200 rating. Operating temperature limited to 125°C. Suitable for general industrial applications where automotive qualification is not required.

RMCF0201FT41R2 (Stackpole Electronics): Includes AEC-Q200 qualification with full 155°C operating temperature support. Stackpole RMCF series provides alternative sourcing for automotive-grade applications.

ERJ-1GNF41R2C (Panasonic): Panasonic ERJ-1GN series offering without explicit AEC-Q200 rating. Operating temperature limited to 125°C. Provides alternative sourcing from established manufacturer.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0741R2L replace AC0201FR-0741R2L in automotive applications?

A: RC0201FR-0741R2L meets all core electrical and mechanical specifications but lacks explicit AEC-Q200 automotive qualification. Substitution is permissible only if your application does not mandate AEC-Q200 certification. Operating temperature is limited to 125°C versus 155°C for the AC variant.

Q: What is the difference between RMCF0201FT41R2 and AC0201FR-0741R2L?

A: Both parts are AEC-Q200 qualified and support -55°C to 155°C operating range. RMCF0201FT41R2 is manufactured by Stackpole Electronics and provides equivalent electrical performance. Maximum seated height differs slightly (0.011" vs 0.010"), which is negligible for 0201 package applications.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. AC0201FR-0741R2L, RC0201FR-0741R2L, RMCF0201FT41R2, and ERJ-1GNF41R2C are all supplied in Tape & Reel (TR) packaging format.

Q: Which substitute offers the highest inventory availability?

A: ERJ-1GNF41R2C (Panasonic) has 47,285 units in stock, followed by RC0201FR-0741R2L (YAGEO) with 10,952 units and RMCF0201FT41R2 (Stackpole) with 10,388 units.

Q: Can ERJ-1GNF41R2C be used in applications requiring 155°C operation?

A: No. ERJ-1GNF41R2C is rated for -55°C to 125°C maximum. For applications requiring 155°C operation, use AC0201FR-0741R2L or RMCF0201FT41R2.
