Frequently Asked Questions (FAQ)

Q: Can ERJ-6GEYJ221V replace RMC1/10-221JTP in all applications?

A: ERJ-6GEYJ221V is a parametric equivalent with identical electrical specifications (220 Ω, ±5%, 0.125W, ±200ppm/°C, -55°C to 155°C). The primary difference is packaging format: ERJ-6GEYJ221V is supplied in Cut Tape (CT) & Digi-Reel® while RMC1/10-221JTP uses Tape & Reel (TR). Both formats are compatible with standard pick-and-place equipment. ERJ-6GEYJ221V includes AEC-Q200 automotive certification, providing enhanced reliability for automotive applications.

Q: What is the difference between the ±5% tolerance parts and ±1% tolerance parts?

A: The main electrical difference is tolerance: ±5% parts (RMC1/10-221JTP, ERJ-6GEYJ221V, KTR10EZPJ221, RMCF0805JT220R, RC0805JR-07220RL) allow resistance values between 209 Ω and 231 Ω, while ±1% parts (CRG0805F220R, ERJ-6ENF2200V, RC0805FR-07220RL, RMCF0805FT220R) allow values between 217.8 Ω and 222.2 Ω.

A: CRG0805F220R is mechanically and functionally compatible with identical package, power rating, and operating temperature range. Electrically, CRG0805F220R offers improved specifications: ±1% tolerance (versus ±5%) and ±100ppm/°C temperature coefficient (versus ±200ppm/°C). This represents an upgrade in performance characteristics. Circuits designed for ±5% tolerance will operate correctly with ±1% components.

Q: What packaging format differences exist among the substitute parts?

A: Substitute parts are supplied in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel®. Tape & Reel format is standard for high-volume automated assembly. Cut Tape & Digi-Reel® format provides flexibility for lower-volume or mixed-component orders.
