Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F84R5CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 84.5 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W specification. Higher power ratings provide enhanced thermal performance without affecting electrical compatibility.
• Features: Substitute parts may include additional certifications (such as AEC-Q200 automotive qualification) beyond the base moisture resistance specification.

All identified substitute parts meet these criteria and are packaged in Tape & Reel (TR) format consistent with the original component.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (RC0402FR-0784R5L by YAGEO): This part matches all electrical and mechanical specifications of the RC1005F84R5CS. Both components share identical resistance, tolerance, power rating, package dimensions, and operating characteristics. Selection of this substitute is appropriate for applications requiring direct functional equivalence without additional certifications.

Upgraded Option (ERJ-2RKF84R5X by Panasonic): This part exceeds the power rating specification (0.1W versus 0.063W) and includes AEC-Q200 automotive qualification. The higher power rating provides additional thermal margin. This substitute is suitable for applications requiring automotive-grade reliability or where thermal performance enhancement is beneficial.

Automotive-Qualified Alternatives (CRCW040284R5FKED by Vishay Dale and RMCF0402FT84R5 by Stackpole): Both parts maintain the original 0.063W power rating while adding AEC-Q200 automotive certification. These substitutes are appropriate for designs requiring automotive qualification without power rating changes. CRCW040284R5FKED offers higher inventory availability (39,470 units), while RMCF0402FT84R5 provides an alternative from Stackpole Electronics.

All substitute parts are ROHS3 compliant, MSL 1 rated, and maintain the -55°C to 155°C operating temperature range of the original component.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0784R5L replace RC1005F84R5CS in any application? A: Yes. RC0402FR-0784R5L is a direct equivalent with identical electrical specifications, tolerance, power rating, and package dimensions. No design modifications are required.

Q: What is the difference between the 0.063W and 0.1W power ratings? A: The 0.1W rating (ERJ-2RKF84R5X) provides higher power dissipation capability than the 0.063W specification. In applications operating at or below 0.063W, both ratings are functionally equivalent. The higher rating offers additional thermal margin and is suitable for designs with elevated power dissipation requirements.

Q: Are the automotive-qualified parts (AEC-Q200) compatible with non-automotive applications? A: Yes. AEC-Q200 certification indicates enhanced reliability testing and qualification. These parts meet or exceed the specifications of non-automotive equivalents and are fully compatible with general industrial and consumer applications.

Q: Does package size differ between these substitute parts? A: No. All substitute parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints and assembly processes are identical.

Q: What is MSL 1 rating and why does it matter? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1, meaning they can be stored and handled without special moisture control procedures.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant, matching the environmental compliance status of the RC1005F84R5CS.

Q: Which substitute offers the best inventory availability? A: RC0402FR-0784R5L (YAGEO) provides the highest inventory with 103,351 units in stock, followed by ERJ-2RKF84R5X (Panasonic) with 110,095 units. CRCW040284R5FKED (Vishay Dale) has 39,470 units available.
