Parameter Comparison

Engineering Selection Recommendations

RC1608F1R1CS (Samsung Electro-Mechanics): Primary selection for applications without automotive qualification requirements. Active product status with established supply (1117 pcs in stock). Suitable for consumer and industrial applications requiring moisture-resistant thick film construction.

KTR03EZPF1R10 (Rohm Semiconductor): Direct substitute with automotive AEC-Q200 qualification. Superior temperature coefficient performance (±200ppm/°C vs ±300ppm/°C). High voltage capability designation. Recommended for automotive applications or designs requiring enhanced temperature stability. Largest available inventory (14034 pcs).

RMCF0603FT1R10 (Stackpole Electronics Inc): Direct substitute with automotive AEC-Q200 qualification. Temperature coefficient performance equivalent to Rohm part (±200ppm/°C). Highest inventory availability (78976 pcs). Suitable for automotive applications and high-volume production requiring assured supply continuity.

All three parts maintain identical electrical performance within specified tolerance bands and operate across the full -55°C to 155°C temperature range. Selection between substitutes depends on supply availability, automotive qualification requirements, and inventory positioning.

Frequently Asked Questions (FAQ)

Q: Can KTR03EZPF1R10 and RMCF0603FT1R10 be used interchangeably with RC1608F1R1CS?

A: Yes. Both substitute parts meet all mandatory electrical specifications (1.1 Ohms ±1%, 0.1W power rating), mechanical requirements (0603 package, 2 terminations), and compliance standards (ROHS3, REACH Unaffected, MSL 1). Functional interchangeability is confirmed across the full operating temperature range.

Q: What is the difference in temperature coefficient between the main part and substitutes?

A: RC1608F1R1CS has a temperature coefficient of ±300ppm/°C. Both KTR03EZPF1R10 and RMCF0603FT1R10 have ±200ppm/°C. The substitute parts provide superior temperature stability. This difference does not affect interchangeability but indicates enhanced performance in temperature-sensitive applications.

Q: Are the automotive AEC-Q200 qualifications on substitute parts relevant for non-automotive applications?

A: AEC-Q200 qualification indicates enhanced reliability testing and quality standards. These qualifications do not restrict use in non-automotive applications. Parts qualified to automotive standards are suitable for any application requiring equivalent or higher reliability levels.

Q: Do the dimensional variations between parts affect PCB layout or assembly?

A: No. RMCF0603FT1R10 has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for the other parts. This 0.05mm difference falls within standard PCB design tolerances and does not affect placement, soldering, or functional performance. All parts maintain identical height (0.022" / 0.55mm maximum) and width (0.031" / 0.80mm).

Q: Which substitute part should be selected for maximum supply assurance?

A: RMCF0603FT1R10 (Stackpole Electronics Inc) offers the highest inventory level at 78976 pieces, providing maximum supply continuity. KTR03EZPF1R10 (Rohm Semiconductor) with 14034 pieces provides secondary supply assurance with automotive qualification.

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

A: Yes. RC1608F1R1CS, KTR03EZPF1R10, and RMCF0603FT1R10 are all supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
