Engineering Selection Recommendations

Primary Selection (Active Status, Full Temperature Range): RC0201FR-07604RL (YAGEO) and CRCW0201604RFNED (Vishay Dale) are recommended as primary substitutes. Both parts are in active production, ROHS3 compliant, and support the full -55°C to 155°C operating temperature range of the original AC0201FR-07604RL. RC0201FR-07604RL offers the highest inventory availability (77,492 units).

Automotive Applications: For designs requiring automotive AEC-Q200 qualification, AC0201FR-07604RL (original) and RK73H1HTTC6040F (KOA Speer) are qualified alternatives. Note that RK73H1HTTC6040F carries "Not For New Designs" status; use only when existing designs require continuation or when new design qualification is not required.

Temperature-Constrained Applications: RC0201FR-07604RL and ERJ-1GNF6040C operate to -55°C ~ 125°C. These parts are suitable for applications where the upper temperature limit does not exceed 125°C. ERJ-1GNF6040C (Panasonic) provides the highest inventory level (85,645 units) among all listed parts.

General Industrial Applications: RMCF0201FT604R (Stackpole Electronics) is an active production alternative with full -55°C to 155°C temperature range and AEC-Q200 rating, supporting general industrial and automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-07604RL replace AC0201FR-07604RL in all applications? A: RC0201FR-07604RL is electrically and mechanically equivalent and suitable for applications operating within -55°C to 125°C. Applications requiring operation above 125°C must use parts rated to 155°C (AC0201FR-07604RL, CRCW0201604RFNED, RK73H1HTTC6040F, or RMCF0201FT604R).

Q: What is the difference between parts marked "Active" and "Not For New Designs"? A: Parts with "Active" status are in current production and recommended for new designs. RK73H1HTTC6040F is marked "Not For New Designs," indicating the manufacturer is phasing out this product line. Use only for design continuation or legacy applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts (AC0201FR-07604RL, RC0201FR-07604RL, CRCW0201604RFNED, RK73H1HTTC6040F, RMCF0201FT604R, and ERJ-1GNF6040C) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best availability? A: ERJ-1GNF6040C (Panasonic) has the highest inventory at 85,645 units. RC0201FR-07604RL (YAGEO) is the second option with 77,492 units available.

Q: Can I use CRCW0201604RFNED in automotive applications? A: CRCW0201604RFNED does not carry AEC-Q200 automotive qualification. For automotive applications, use AC0201FR-07604RL, RK73H1HTTC6040F, or RMCF0201FT604R.

Q: Are there any physical dimension differences between substitutes? A: All parts use the 0201 package (0.60mm × 0.30mm). Maximum seated height is 0.010" (0.26mm) for most parts, with RMCF0201FT604R at 0.011" (0.28mm). This minor variation does not affect PCB layout compatibility.
