Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: Select from KTR03EZPF2703, CRCW0603270KFKEA, ERJ-3EKF2703V, or RMCF0603FT270K. All four parts maintain full AEC-Q200 compliance and are currently in active production status. KTR03EZPF2703 offers the advantage of same-manufacturer continuity with Rohm Semiconductor and includes high voltage capability. ERJ-3EKF2703V and RMCF0603FT270K provide the highest inventory availability.

For Non-Automotive Applications with Moisture Resistance: CR0603-FX-2703ELF (Bourns Inc.) and RC0603FR-07270KL (YAGEO) are suitable alternatives. These parts do not carry AEC-Q200 certification but meet all core electrical and mechanical specifications with moisture-resistant composition. RC0603FR-07270KL offers significantly higher inventory availability.

For Immediate Availability: ERJ-3EKF2703V (67,363 pcs) and RC0603FR-07270KL (124,369 pcs) provide the largest stock quantities.

For Compliance Continuity: All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2703ELF or RC0603FR-07270KL as direct replacements for MCR03EZPFX2703 in automotive applications?

A: CR0603-FX-2703ELF and RC0603FR-07270KL meet all electrical and mechanical specifications (270 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C ~ 155°C). However, they do not carry AEC-Q200 automotive qualification. Use only if your application does not require AEC-Q200 certification.

Q: What is the difference between the MCR03EZPFX2703 and KTR03EZPF2703?

A: Both are Rohm Semiconductor 270 kOhms ±1% 0603 thick film resistors with identical electrical specifications and AEC-Q200 rating. The primary difference is product status: MCR03EZPFX2703 is discontinued, while KTR03EZPF2703 is active. KTR03EZPF2703 includes high voltage capability and higher inventory availability (4,378 pcs vs. 3,124 pcs).

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in 0603 (1608 Metric) package. Packaging options vary by supplier: KTR03EZPF2703 is supplied in Tape & Reel (TR); CRCW0603270KFKEA in Cut Tape (CT) & Digi-Reel®; ERJ-3EKF2703V, RMCF0603FT270K, CR0603-FX-2703ELF, and RC0603FR-07270KL in Tape & Reel (TR).

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original MCR03EZPFX2703 environmental compliance requirements.

Q: Which substitute offers the best long-term availability?

A: ERJ-3EKF2703V (Panasonic) and RMCF0603FT270K (Stackpole) are both active products with high inventory levels (67,363 pcs and 64,038 pcs respectively) and full AEC-Q200 compliance, making them suitable for long-term production planning.
