Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• Resistance value: 210 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
• MSL rating: 1 (Unlimited)
• RoHS3 compliance

Substitution Categories:

Direct Equivalents meet all primary criteria with identical packaging specifications and no additional certifications:

• CR0603-FX-2103ELF (Bourns Inc.)
• RC0603FR-07210KL (YAGEO)

Functionally Compatible Substitutes meet all primary criteria with automotive AEC-Q200 qualification, which represents enhanced reliability and does not restrict use in non-automotive applications:

• AC0603FR-07210KL (YAGEO)
• CRCW0603210KFKEA (Vishay Dale)
• ERJ-3EKF2103V (Panasonic Electronic Components)
• RMCF0603FT210K (Stackpole Electronics Inc)

All substitute parts maintain identical electrical performance, thermal characteristics, and environmental compliance as the primary part RC1608F2103CS.

Parameter Comparison

Engineering Selection Recommendations

These components are suitable for applications requiring automotive-grade reliability without functional or electrical compromise.

Inventory Availability Consideration: All substitute parts maintain Active product status. ERJ-3EKF2103V (Panasonic) offers highest inventory availability at 110,324 pieces. RC0603FR-07210KL (YAGEO) provides 64,206 pieces. RMCF0603FT210K (Stackpole) maintains 80,013 pieces.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F2103CS with CR0603-FX-2103ELF on my circuit board?

A: Yes. CR0603-FX-2103ELF meets all electrical specifications (210 kΩ ±1%, 0.1W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (0603). Both components are RoHS3 compliant with MSL 1 rating. Direct board-level substitution is supported.

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

A: Direct equivalents (CR0603-FX-2103ELF, RC0603FR-07210KL) match all electrical and mechanical specifications without automotive certification. AEC-Q200 qualified parts (AC0603FR-07210KL, CRCW0603210KFKEA, ERJ-3EKF2103V, RMCF0603FT210K) include additional automotive reliability testing and qualification. Both categories are functionally interchangeable; AEC-Q200 parts provide enhanced qualification documentation for automotive applications.

Q: Are there dimensional differences between substitute parts?

A: Nominal package dimensions are 0603 (1608 Metric) for all parts. Minor variations exist in seated height: RC1608F2103CS, CR0603-FX-2103ELF, RC0603FR-07210KL, AC0603FR-07210KL, and ERJ-3EKF2103V specify 0.022" (0.55mm) maximum seated height. CRCW0603210KFKEA specifies 0.020" (0.50mm) and RMCF0603FT210K specifies 0.022" (0.55mm). These variations remain within standard 0603 package tolerance and do not affect PCB assembly compatibility.

Q: Which substitute part should I select for cost optimization?

A: Selection depends on application requirements and supply chain factors. Direct equivalents (CR0603-FX-2103ELF, RC0603FR-07210KL) typically offer cost parity with RC1608F2103CS. AEC-Q200 qualified parts may carry cost premiums proportional to automotive qualification documentation. Consult current inventory pricing and lead time data for final procurement decisions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance identical to RC1608F2103CS. All components are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: Can I use these parts interchangeably in production?

A: Yes, within the constraints of your design specifications. All substitute parts maintain identical electrical performance (210 kΩ ±1%, 0.1W), thermal stability (±100ppm/°C, -55°C to 155°C), and environmental ratings (MSL 1, RoHS3). Verify packaging format (Cut Tape vs. Tape & Reel) matches your assembly process requirements.
