Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F4873CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 487 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W (1/16W) specification
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component procurement

The identified substitute parts are grouped as follows:

Direct Equivalent: RC0402FR-07487KL (YAGEO) matches all parameters including identical power rating and packaging format.

Upgrade Specification: ERJ-2RKF4873X (Panasonic Electronic Components) provides enhanced power rating of 0.1W (1/10W) with automotive AEC-Q200 qualification, suitable for applications requiring higher thermal margin.

Similar Specification: CRCW0402487KFKED (Vishay Dale) and RMCF0402FT487K (Stackpole Electronics Inc) maintain identical electrical and mechanical specifications with automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RC0402FR-07487KL (YAGEO) is the direct equivalent substitute with identical electrical specifications, power rating, and packaging. This part is suitable for direct replacement in non-automotive applications where the original Samsung part is unavailable. Active product status and ROHS3 compliance ensure continued supply and regulatory conformance.

ERJ-2RKF4873X (Panasonic Electronic Components) provides an upgrade path with enhanced power rating of 0.1W (1/10W) and automotive AEC-Q200 qualification. This part is appropriate for applications requiring automotive-grade reliability or thermal margin beyond the original 0.063W specification. The increased power rating does not compromise circuit performance in applications designed for the lower rating.

CRCW0402487KFKED (Vishay Dale) and RMCF0402FT487K (Stackpole Electronics Inc) maintain specification parity with the original part while offering automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade components or where supply diversification across multiple qualified manufacturers is required. Both parts maintain identical electrical and mechanical compatibility with the RC1005F4873CS.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and Active product status, ensuring regulatory conformance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07487KL replace RC1005F4873CS in all applications?

A: Yes. RC0402FR-07487KL is a direct equivalent with identical resistance, tolerance, power rating, package dimensions, and operating temperature range. The only difference is the packaging format (Cut Tape & Digi-Reel versus Tape & Reel), which does not affect component performance or circuit compatibility.

Q: What is the advantage of using ERJ-2RKF4873X over the original RC1005F4873CS?

A: ERJ-2RKF4873X provides a higher power rating of 0.1W (1/10W) compared to the original 0.063W (1/16W), offering increased thermal margin. Additionally, it carries automotive AEC-Q200 qualification, making it suitable for automotive applications or designs requiring enhanced reliability standards.

Q: Are CRCW0402487KFKED and RMCF0402FT487K interchangeable with RC1005F4873CS?

A: Yes. Both parts match the original specification across all critical parameters: 487 kOhms ±1%, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both carry automotive AEC-Q200 qualification, providing additional reliability assurance.

Q: Does the packaging format (Tape & Reel versus Cut Tape) affect component selection?

A: No. Packaging format differences (Tape & Reel or Cut Tape & Digi-Reel) do not affect electrical performance or circuit compatibility. Selection between formats is determined by manufacturing equipment compatibility and procurement requirements.

Q: Can I use an automotive AEC-Q200 qualified part in a non-automotive application?

A: Yes. Automotive-qualified parts (ERJ-2RKF4873X, CRCW0402487KFKED, RMCF0402FT487K) meet or exceed the specifications of non-automotive equivalents and are fully compatible with non-automotive designs. The automotive qualification represents an additional quality assurance level.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. This classification allows extended storage without desiccant packaging requirements and simplifies inventory management compared to higher MSL ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance, ensuring regulatory conformance for applications subject to RoHS directives and environmental regulations.
