Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F7680CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (768 Ohms), tolerance (±1%), and power rating (0.1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0603 / 1608 Metric) and number of terminations (2) ensure physical fit and solderability on printed circuit boards. Dimensional variations within supplier device package specifications are permissible provided they do not exceed standard 0603 envelope limits.

Compliance & Environmental: RoHS3 compliance and MSL Level 1 classification are baseline requirements. REACH Unaffected status applies uniformly across all listed parts.

Composition & Construction: Thick film construction is the specified technology. Moisture resistance is a required feature for all substitutes.

Substitute parts are categorized as Direct Equivalent (RC0603FR-07768RL) when all parameters match without additional certifications, and Similar Equivalents when automotive AEC-Q200 qualification is added (AC0603FR-07768RL, CRCW0603768RFKEA, ERJ-3EKF7680V, RMCF0603FT768R).

Compliance Consistency: All substitute parts are ROHS3 compliant and REACH Unaffected, maintaining regulatory alignment with the original component across global markets.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07768RL replace RC1608F7680CS in any application?

A: RC0603FR-07768RL is a direct electrical and mechanical equivalent. Substitution is valid for all applications where the original component is specified, provided no additional automotive or military qualification requirements exist.

Q: What is the difference between the YAGEO RC0603FR-07768RL and AC0603FR-07768RL?

A: Both parts are manufactured by YAGEO with identical electrical specifications (768 Ohms ±1%, 0.1W, 0603 package). The AC0603FR-07768RL includes AEC-Q200 automotive qualification, making it suitable for automotive applications requiring enhanced reliability documentation. The RC0603FR-07768RL is intended for general-purpose applications.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations exist within supplier specifications. CRCW0603768RFKEA (Vishay Dale) and RMCF0603FT768R (Stackpole) have slightly different length and height specifications compared to the original RC1608F7680CS, but all remain within standard 0603 package envelope limits and are compatible with standard PCB footprints.

Q: Which substitute part offers the highest inventory availability?

A: RC0603FR-07768RL (YAGEO) has the highest documented inventory at 124,839 pieces. ERJ-3EKF7680V (Panasonic) follows with 78,934 pieces. Inventory levels are subject to change and should be verified with suppliers.

Q: Can automotive-qualified parts be used in non-automotive applications?

A: Yes. Automotive-qualified parts (AC0603FR-07768RL, CRCW0603768RFKEA, ERJ-3EKF7680V, RMCF0603FT768R) exceed the performance and reliability requirements of general-purpose applications and are fully compatible with non-automotive designs.

Q: Is moisture resistance a critical feature for all substitutes?

A: Yes. Moisture resistance is a required feature specified for the original RC1608F7680CS and all listed substitute parts. All parts are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of ±100ppm/°C temperature coefficient?

A: The ±100ppm/°C temperature coefficient defines the maximum resistance change per degree Celsius across the operating temperature range (-55°C ~ 155°C). All substitute parts maintain this specification, ensuring consistent performance across thermal extremes.
