Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4870CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W (1/16W) rating of the main part. Higher power ratings provide equivalent or superior performance in the same package footprint.
• Packaging Format: Tape & Reel (TR) is the primary format; Cut Tape (CT) variants are functionally equivalent for component selection.
• Features: Additional certifications (Automotive AEC-Q200) or enhanced features (Moisture Resistant) do not disqualify substitution.

All identified substitute parts meet these criteria and are classified as direct equivalents or upgrades based on power rating and feature enhancements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are functionally equivalent to the RC1005F4870CS based on electrical specifications, mechanical dimensions, and regulatory compliance. Selection among these alternatives is determined by the following factors:

Direct Equivalents (Identical Specifications): CR0402-FX-4870GLF (Bourns Inc.), RC0402FR-07487RL (YAGEO), CRCW0402487RFKED (Vishay Dale), and RMCF0402FT487R (Stackpole Electronics Inc.) provide direct substitution with matching 0.063W power ratings and identical electrical parameters.

Upgrade Option (Enhanced Power Rating): ERJ-2RKF4870X (Panasonic Electronic Components) provides a 0.1W (1/10W) power rating in the same 0402 package footprint. This higher power rating supports applications requiring greater thermal margin without any compromise to electrical performance or physical compatibility.

Automotive Qualification: CRCW0402487RFKED, RMCF0402FT487R, and ERJ-2RKF4870X carry Automotive AEC-Q200 certification. These parts are suitable for automotive and high-reliability applications where this qualification is specified.

Inventory and Availability: All substitute parts maintain active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Selection may be based on procurement lead times, inventory availability, or preferred supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-4870GLF replace RC1005F4870CS in all applications?

A: Yes. CR0402-FX-4870GLF is a direct equivalent with identical resistance (487 Ohms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and ERJ-2RKF4870X?

A: ERJ-2RKF4870X has a higher power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) rating of RC1005F4870CS. All other electrical and mechanical parameters are identical. The higher power rating provides additional thermal capacity in the same physical package.

Q: Are the Automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 qualification indicates enhanced reliability testing and quality standards. These parts (CRCW0402487RFKED, RMCF0402FT487R, ERJ-2RKF4870X) are suitable for any application requiring the specified electrical and mechanical parameters, including non-automotive designs.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. CRCW0402487RFKED is available in Cut Tape (CT) & Digi-Reel® format while other substitutes use standard Tape & Reel (TR). Electrical and mechanical specifications remain identical.

Q: Can I use a substitute part with higher power rating in a design specified for 0.063W?

A: Yes. ERJ-2RKF4870X (0.1W rating) is a direct substitute for applications specified at 0.063W. The higher power rating provides equivalent or superior performance with no adverse effects on circuit operation or reliability.

Q: Are all substitute parts moisture resistant?

A: RC1005F4870CS and RC0402FR-07487RL explicitly feature moisture resistant construction. CR0402-FX-4870GLF, ERJ-2RKF4870X, CRCW0402487RFKED, and RMCF0402FT487R do not list moisture resistant as a specified feature. However, all parts maintain MSL 1 (Unlimited) rating, indicating compatibility with standard PCB assembly processes.

Q: What is the temperature coefficient specification and why does it matter?

A: All parts specify ±100ppm/°C temperature coefficient, meaning resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification ensures predictable performance across the -55°C to 155°C operating range and is critical for precision analog circuits.

Q: Can these 0402 package resistors be hand-soldered?

A: The 0402 (1.00mm x 0.50mm) package is classified as a micro-component. While technically hand-solderable, it requires specialized equipment and expertise. Standard assembly practice uses automated pick-and-place and reflow soldering processes.
