Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F4872CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (48.7 kOhms), tolerance (±1%), and power rating (0.1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0603 / 1608 Metric) and number of terminations (2) are mandatory for PCB footprint compatibility. Physical dimensions (length, width, height) must accommodate standard 0603 land patterns.

Environmental & Compliance Requirements: All substitute parts must maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Composition (thick film) and moisture resistance features ensure functional equivalence.

Packaging Format: Tape & Reel (TR) packaging is standard across all listed substitutes, supporting automated assembly processes.

Substitute parts are categorized as Direct Manufacturer equivalents (functionally identical across all parameters) or Similar parts (functionally equivalent with additional certifications such as Automotive AEC-Q200 qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalents:

CR0603-FX-4872ELF (Bourns Inc.) and RC0603FR-0748K7L (YAGEO) are direct functional equivalents to the RC1608F4872CS. Both parts match all electrical and mechanical specifications without additional certifications. These options are suitable for general-purpose applications where automotive qualification is not required.

Automotive-Qualified Alternatives:

AC0603FR-0748K7L (YAGEO), CRCW060348K7FKEA (Vishay Dale), ERJ-3EKF4872V (Panasonic Electronic Components), and RMCF0603FT48K7 (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards. These parts maintain identical electrical and mechanical specifications while providing additional reliability assurance for automotive and high-reliability applications. Selection among these options depends on supply chain availability and preferred manufacturer relationships.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory compatibility across global markets.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-4872ELF replace RC1608F4872CS directly on a PCB?

A: Yes. CR0603-FX-4872ELF is a direct equivalent with identical resistance (48.7 kOhms), tolerance (±1%), power rating (0.1W), package (0603), and operating temperature range (-55°C to 155°C). No circuit redesign or PCB layout modification is required.

Q: What is the difference between direct equivalents and AEC-Q200 qualified parts?

A: Direct equivalents (CR0603-FX-4872ELF, RC0603FR-0748K7L) provide functional interchangeability for standard applications. AEC-Q200 qualified parts (AC0603FR-0748K7L, CRCW060348K7FKEA, ERJ-3EKF4872V, RMCF0603FT48K7) include automotive-grade reliability testing and qualification, suitable for automotive and mission-critical applications. Electrical and mechanical specifications remain identical.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly processes.

Q: Do substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use CRCW060348K7FKEA in place of RC1608F4872CS in a non-automotive application?

A: Yes. CRCW060348K7FKEA meets all electrical and mechanical requirements of RC1608F4872CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. The part is fully compatible.

Q: What is the temperature coefficient significance for these resistors?

A: All listed parts share a temperature coefficient of ±100ppm/°C, ensuring consistent resistance stability across the operating temperature range (-55°C to 155°C). This parameter is critical for precision analog circuits and must remain constant across substitutions.

Q: Are there physical dimension variations among substitute parts?

A: Minor variations exist within 0603 package tolerances. CRCW060348K7FKEA and RMCF0603FT48K7 have slightly different length and height specifications compared to the main part, but these differences remain within standard 0603 PCB footprint tolerances and do not affect interchangeability.
