Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F4873CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (487 kOhms), tolerance (±1%), and power rating (0.1W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package designation (0603 / 1608 Metric) and number of terminations (2) ensure physical and electrical interface compatibility on printed circuit boards.

Environmental & Compliance Parameters: RoHS3 compliance, MSL 1 rating, and REACH unaffected status maintain regulatory and manufacturing process alignment.

All identified substitute parts meet these criteria without exception. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the RC1608F4873CS. Selection among these alternatives is based on:

Product Status: All parts carry Active status, confirming current manufacturing availability and supply chain viability.

Compliance Certification: All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements identical to the primary part.

Automotive Qualification: Parts AC0603FR-07487KL, CRCW0603487KFKEA, ERJ-3EKF4873V, and RMCF0603FT487K carry AEC-Q200 automotive qualification. The primary part RC1608F4873CS and YAGEO RC0603FR-07487KL do not specify this rating. AEC-Q200 qualification is an additional feature that does not preclude use in non-automotive applications.

Packaging Considerations: Tape & Reel packaging is standard for high-volume automated assembly. AC0603FR-07487KL is supplied in Cut Tape & Digi-Reel format, suitable for lower-volume or mixed-component procurement workflows.

Inventory Availability: Substitute parts demonstrate substantial stock levels across multiple manufacturers, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0603FR-07487KL for RC1608F4873CS in my circuit design?

A: Yes. RC0603FR-07487KL is a direct electrical and mechanical equivalent. Both parts share identical resistance (487 kΩ), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance status (ROHS3, MSL 1). No circuit redesign or validation is required.

Q: What is the difference between AC0603FR-07487KL and RC0603FR-07487KL?

A: Both are YAGEO 487 kΩ ±1% 0.1W 0603 resistors with identical electrical specifications. AC0603FR-07487KL includes AEC-Q200 automotive qualification and is supplied in Cut Tape & Digi-Reel packaging. RC0603FR-07487KL is supplied in Tape & Reel format without automotive qualification. For non-automotive applications, either part is functionally equivalent.

Q: Are the dimensional variations between CRCW0603487KFKEA (1.55mm x 0.85mm) and RC1608F4873CS (1.60mm x 0.80mm) significant?

A: No. Both parts conform to the 0603 (1608 Metric) package standard. The minor dimensional differences fall within standard manufacturing tolerances for this package class and do not affect circuit board layout, footprint compatibility, or electrical performance.

Q: Can I use ERJ-3EKF4873V in a non-automotive application?

A: Yes. ERJ-3EKF4873V meets all electrical and environmental specifications required for the RC1608F4873CS. AEC-Q200 automotive qualification is an additional certification that does not restrict use in general-purpose applications. The part is fully compatible.

Q: Does packaging type (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging type affects procurement, handling, and assembly logistics only. Electrical and mechanical properties are identical. AC0603FR-07487KL (Cut Tape & Digi-Reel) and RC0603FR-07487KL (Tape & Reel) are electrically interchangeable.

Q: Which substitute part should I select for maximum supply availability?

A: ERJ-3EKF4873V (Panasonic) shows the highest inventory level at 69,652 pieces. CRCW0603487KFKEA (Vishay Dale) follows at 35,200 pieces. Both represent substantial stock positions suitable for production requirements.
