Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F2803CS are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Parameters (Must Match):

• Resistance value: 280 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Regulatory & Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all electrical, mechanical, and regulatory parameters with identical or equivalent packaging specifications.

Similar Substitutes: Parts meeting all core electrical and mechanical parameters with additional automotive-grade certifications (AEC-Q200) or minor dimensional variations within acceptable tolerances for PCB assembly.

Engineering Selection Recommendations

Direct Substitution (Preferred for General Applications):

CR0603-FX-2803ELF (Bourns Inc.) and RC0603FR-07280KL (YAGEO) are direct substitutes for RC1608F2803CS. Both parts match all electrical specifications, mechanical dimensions, and regulatory compliance requirements. These parts maintain identical moisture sensitivity levels and RoHS3 compliance status. Selection between these options depends on packaging format availability: CR0603-FX-2803ELF is supplied in Tape & Reel format, while RC0603FR-07280KL is available in Cut Tape and Digi-Reel formats.

Automotive-Grade Substitution (For AEC-Q200 Qualified Applications):

AC0603FR-07280KL (YAGEO), CRCW0603280KFKEA (Vishay Dale), ERJ-3EKF2803V (Panasonic Electronic Components), and RMCF0603FT280K (Stackpole Electronics Inc) are qualified substitutes with automotive AEC-Q200 certification. These parts maintain all core electrical and mechanical parameters while providing additional automotive-grade reliability qualification. These substitutes are suitable for applications requiring automotive-level component qualification or where AEC-Q200 compliance is specified in design requirements.

All substitute parts maintain Active product status and REACH Unaffected compliance status, ensuring continued availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2803ELF replace RC1608F2803CS in any application?

A: CR0603-FX-2803ELF is a direct substitute for RC1608F2803CS. Both parts share identical electrical specifications (280 kOhms ±1%, 0.1W), mechanical package dimensions (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). Direct substitution is valid without design modification.

Q: What is the difference between direct substitutes and automotive-grade substitutes?

A: Direct substitutes (CR0603-FX-2803ELF, RC0603FR-07280KL) match all electrical and mechanical parameters of the RC1608F2803CS without additional certifications. Automotive-grade substitutes (AC0603FR-07280KL, CRCW0603280KFKEA, ERJ-3EKF2803V, RMCF0603FT280K) include AEC-Q200 automotive qualification in addition to matching all core specifications. Automotive-grade parts are required only when design specifications explicitly require AEC-Q200 compliance.

Q: Are there dimensional differences between substitute parts?

A: All substitute parts conform to the 0603 (1608 Metric) package standard. Minor dimensional variations exist within manufacturing tolerances: most parts measure 0.063" L x 0.031" W (1.60mm x 0.80mm), while CRCW0603280KFKEA and RMCF0603FT280K measure 0.061" L x 0.031" W to 0.033" W (1.55mm x 0.80mm to 0.85mm). These variations remain within standard PCB assembly tolerances and do not affect interchangeability.

Q: Can I use an automotive-grade substitute in a non-automotive application?

A: Automotive-grade substitutes (AC0603FR-07280KL, CRCW0603280KFKEA, ERJ-3EKF2803V, RMCF0603FT280K) are fully compatible with non-automotive applications. These parts meet or exceed all specifications of the RC1608F2803CS and provide additional reliability qualification. Use of automotive-grade parts in non-automotive applications introduces no compatibility issues.

Q: What packaging formats are available for substitute parts?

A: CR0603-FX-2803ELF is supplied in Tape & Reel (TR) format. RC0603FR-07280KL is available in Cut Tape (CT) and Digi-Reel formats. All remaining substitutes (AC0603FR-07280KL, CRCW0603280KFKEA, ERJ-3EKF2803V, RMCF0603FT280K) are supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and volume specifications.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and REACH Unaffected, matching the regulatory compliance status of RC1608F2803CS. This ensures consistent compliance with environmental and hazardous substance regulations across all substitute options.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), identical to RC1608F2803CS. This classification indicates unlimited shelf life without moisture bake requirements prior to soldering, providing equivalent handling and storage characteristics.
