Mandatory Matching Parameters:

• Resistance value: 180 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• MSL rating: 1 (Unlimited)

Substitution Categories:

Direct Equivalents maintain identical electrical and mechanical specifications with no additional certifications or features beyond the base requirements.

Upgrade Substitutes include additional certifications (AEC-Q200 automotive qualification) or enhanced features (high voltage capability) while maintaining all base electrical parameters.

Similar Substitutes include automotive AEC-Q200 certification or enhanced moisture resistance while maintaining electrical equivalence. Minor dimensional variations within tolerance may exist.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0603-FX-1803ELF (Bourns Inc.) and RC0603FR-07180KL (YAGEO) are direct functional equivalents to RC1608F184CS. Both maintain identical electrical specifications, package format, and compliance ratings. Selection between these options is based on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability.

Upgrade Path for Automotive Applications: KTR03EZPF1803 (Rohm Semiconductor), AC0603FR-07180KL (YAGEO), CRCW0603180KFKEA (Vishay Dale), ERJ-3EKF1803V (Panasonic), and RMCF0603FT180K (Stackpole Electronics) all include AEC-Q200 automotive qualification. These parts are suitable for designs requiring automotive-grade reliability and traceability. KTR03EZPF1803 additionally features high voltage capability.

Compliance Verification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07180KL replace RC1608F184CS in my design?

A: Yes. RC0603FR-07180KL (YAGEO) is a direct equivalent with identical resistance (180 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The primary difference is packaging format: RC0603FR-07180KL is supplied in Cut Tape & Digi-Reel format, while RC1608F184CS is supplied in Tape & Reel format.

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

A: Direct equivalents (CR0603-FX-1803ELF, RC0603FR-07180KL) provide identical electrical performance for general industrial applications. AEC-Q200 qualified parts (KTR03EZPF1803, AC0603FR-07180KL, CRCW0603180KFKEA, ERJ-3EKF1803V, RMCF0603FT180K) include automotive-grade qualification, enhanced reliability testing, and traceability documentation required for automotive applications. Electrical specifications remain identical.

Q: Are there dimensional differences between substitute parts?

A: Most substitute parts maintain standard 0603 (1608 Metric) dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). CRCW0603180KFKEA has minor dimensional variation: 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum seated height. RMCF0603FT180K dimensions are 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations remain within standard 0603 package tolerance and do not affect PCB footprint compatibility.

Q: Which substitute part has the highest inventory availability?

A: CRCW0603180KFKEA (Vishay Dale) has the highest inventory level at 5,000,300 pieces. RC0603FR-07180KL (YAGEO) has 90,400 pieces. RMCF0603FT180K (Stackpole Electronics) has 56,186 pieces. CR0603-FX-1803ELF (Bourns Inc.) has 78,356 pieces.

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

A: Yes. AEC-Q200 qualified parts exceed standard industrial specifications and are fully compatible with non-automotive applications. Using automotive-qualified components in industrial designs provides enhanced reliability margin without design modification.

Q: What packaging options are available for 180 kOhms ±1% 0.1W 0603 resistors?
