AC0201FR-0723K2L Equivalent & Substitute Parts

Part Overview

The AC0201FR-0723K2L is a 23.2 kOhms ±1% thick film chip resistor in 0201 package (0.60mm x 0.30mm) rated at 0.05W (1/20W) power dissipation. This YAGEO component is designed for automotive applications with AEC-Q200 qualification and moisture resistance. The part is currently in active production status with 1104 units in stock inventory.

Substitute parts are necessary when the primary manufacturer cannot fulfill supply requirements, when inventory constraints occur, or when design flexibility allows for equivalent alternatives from qualified manufacturers. All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original AC0201FR-0723K2L.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-0723K2L is determined by strict equivalence across the following critical parameters:

• Resistance value: 23.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

All four substitute parts listed below meet these criteria. Variations in operating temperature range, product status, or automotive certifications do not disqualify substitution but are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the AC0201FR-0723K2L and are suitable for direct replacement in applications where the original part is specified.

For new designs or long-term production programs, select from parts with Active product status: CRCW020123K2FNED (Vishay Dale), RMCF0201FT23K2 (Stackpole Electronics), or ERJ-1GNF2322C (Panasonic). The RK73H1HTTC2322F (KOA Speer) carries a "Not For New Designs" status and should be reserved for legacy design support or existing production continuity only.

For automotive applications requiring AEC-Q200 certification, the AC0201FR-0723K2L, RK73H1HTTC2322F, and RMCF0201FT23K2 are explicitly rated. The CRCW020123K2FNED and ERJ-1GNF2322C do not specify AEC-Q200 certification in their datasheets.

For applications operating at the upper temperature limit of 155°C, note that ERJ-1GNF2322C is rated only to 125°C maximum operating temperature. All other parts support the full -55°C to 155°C range.

Inventory availability varies significantly. ERJ-1GNF2322C offers the highest stock level (146136 units), while AC0201FR-0723K2L has the lowest (1104 units).

Frequently Asked Questions (FAQ)

Q: Can CRCW020123K2FNED replace AC0201FR-0723K2L in automotive applications?

A: CRCW020123K2FNED is electrically and mechanically equivalent and meets all core substitution criteria. However, it does not carry explicit AEC-Q200 automotive certification in the provided specifications. For designs requiring AEC-Q200 compliance, use AC0201FR-0723K2L, RK73H1HTTC2322F, or RMCF0201FT23K2 instead.

Q: Why is RK73H1HTTC2322F marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. It remains available for existing production continuity and legacy design support but should not be selected for new product development. Use CRCW020123K2FNED, RMCF0201FT23K2, or ERJ-1GNF2322C for new designs.

Q: Are all substitute parts identical in physical dimensions?

A: All parts share the same 0201 package footprint (0.024" L x 0.012" W). Maximum seated height varies slightly: AC0201FR-0723K2L, CRCW020123K2FNED, RK73H1HTTC2322F, and ERJ-1GNF2322C are rated at 0.010" maximum, while RMCF0201FT23K2 is rated at 0.011" maximum. This 0.001" difference is within typical PCB assembly tolerances and does not affect interchangeability.

Q: What is the difference between the substitute parts in terms of temperature performance?

A: All parts share the same temperature coefficient of ±200ppm/°C. Operating temperature ranges are -55°C to 155°C for AC0201FR-0723K2L, CRCW020123K2FNED, RK73H1HTTC2322F, and RMCF0201FT23K2. ERJ-1GNF2322C has a reduced upper limit of -55°C to 125°C. For applications requiring operation above 125°C, do not use ERJ-1GNF2322C.

Q: Are all parts RoHS3 compliant?

A: Yes. All five parts (AC0201FR-0723K2L, CRCW020123K2FNED, RK73H1HTTC2322F, RMCF0201FT23K2, and ERJ-1GNF2322C) are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best inventory availability?

A: ERJ-1GNF2322C (Panasonic) has the highest stock level at 146136 units. CRCW020123K2FNED (Vishay Dale) offers 29458 units, RMCF0201FT23K2 (Stackpole) has 16904 units, and RK73H1HTTC2322F (KOA Speer) has 11068 units.
