Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6812CS is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 68.1 kOhms (exact)
• Tolerance: ±1% (exact)
• Power rating: 0.1W / 1/10W (exact)
• Package / Case: 0603 (1608 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature coefficient: ±100ppm/°C (exact)
• Operating temperature range: -55°C ~ 155°C (exact)
• Number of terminations: 2 (exact)

Allowable Variations:

• Manufacturer identity (different suppliers acceptable)
• Packaging format (Cut Tape, Tape & Reel, Digi-Reel acceptable)
• Product series designation (RC, CR0603, RC_L, AC, AF, CRCW, ERJ-3EK, RMCF acceptable)
• Additional certifications (AEC-Q200 automotive qualification, anti-sulfur features acceptable as enhancements)
• Minor dimensional tolerances within 0603 package specification
• RoHS compliance status (ROHS3 compliant preferred; non-compliant variants noted)

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical and mechanical specifications) and Similar Parts (identical core specifications with additional certifications or features).

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications (Non-Automotive):

RC0603FR-0768K1L (YAGEO) and CR0603-FX-6812ELF (Bourns Inc.) are direct functional equivalents to RC1608F6812CS. Both maintain identical electrical specifications, ROHS3 compliance, and MSL 1 rating. Selection between these options depends on packaging format availability: Cut Tape for RC0603FR-0768K1L or Tape & Reel for CR0603-FX-6812ELF.

For Automotive Applications (AEC-Q200 Required):

AC0603FR-0768K1L, AF0603FR-0768K1L (YAGEO), CRCW060368K1FKEA, CRCW060368K1FKEB (Vishay Dale), ERJ-3EKF6812V (Panasonic), RMCF0603FG68K1, and RMCF0603FT68K1 (Stackpole) all carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability. RMCF0603FT68K1 offers the highest inventory availability (427,377 pcs) among AEC-Q200 qualified options.

Compliance Considerations:

CRCW060368K1FKTA (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is suitable only for applications where RoHS exemptions apply or legacy system maintenance is required.

Packaging Format Selection:

• Cut Tape (CT): RC0603FR-0768K1L, RMCF0603FG68K1, CRCW060368K1FKEA, CRCW060368K1FKTA
• Tape & Reel (TR): CR0603-FX-6812ELF, AC0603FR-0768K1L, AF0603FR-0768K1L, CRCW060368K1FKEB, ERJ-3EKF6812V, RMCF0603FT68K1
• Cut Tape & Digi-Reel: RC0603FR-0768K1L, CRCW060368K1FKEA, CRCW060368K1FKTA

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0768K1L replace RC1608F6812CS in any application?

A: Yes. RC0603FR-0768K1L is a direct electrical and mechanical equivalent. Both parts share identical resistance (68.1 kΩ), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The primary difference is packaging format: RC1608F6812CS is supplied in Cut Tape, while RC0603FR-0768K1L is available in Cut Tape & Digi-Reel formats.

Q: What is the difference between RMCF0603FT68K1 and RMCF0603FG68K1?

A: Both parts are manufactured by Stackpole Electronics and share identical electrical specifications. The difference is packaging format: RMCF0603FT68K1 is supplied in Tape & Reel (427,377 pcs inventory), while RMCF0603FG68K1 is supplied in Cut Tape (15,276 pcs inventory). Both carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: Are automotive-qualified parts (AEC-Q200) backward compatible with non-automotive applications?

A: Yes. AEC-Q200 qualified parts meet or exceed the electrical and reliability specifications of standard industrial-grade resistors. Parts such as ERJ-3EKF6812V, AC0603FR-0768K1L, and RMCF0603FT68K1 can be used in non-automotive applications without functional or performance degradation.

Q: Why is CRCW060368K1FKTA marked as RoHS non-compliant?

A: CRCW060368K1FKTA is RoHS non-compliant and REACH-affected according to the provided specifications. This part is restricted to applications where RoHS exemptions are applicable or where legacy component compatibility is required. For new designs, ROHS3-compliant alternatives such as CRCW060368K1FKEA or CRCW060368K1FKEB are recommended.

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

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without special moisture control requirements. All listed substitute parts carry MSL 1 rating, meaning they do not require baking or desiccant storage prior to assembly. This simplifies inventory management and reduces handling complexity.

Q: Can I substitute a Tape & Reel packaged part for a Cut Tape part in production?

A: Substitution depends on assembly equipment capability. Tape & Reel format is standard for automated pick-and-place systems, while Cut Tape is suitable for manual assembly or specialized feeders. Verify that your assembly equipment supports the packaging format of the substitute part before implementation.

Q: Which substitute part offers the best inventory availability?

A: RMCF0603FT68K1 (Stackpole Electronics) offers the highest inventory availability at 427,377 pcs. This part is AEC-Q200 qualified, ROHS3 compliant, and supplied in Tape & Reel format, making it suitable for high-volume production requiring automotive-grade reliability.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 0603 package specification. RMCF0603FG68K1 and RMCF0603FT68K1 have dimensions of 0.061" L x 0.031" W (1.55mm x 0.80mm), while most other parts are 0.063" L x 0.031" W (1.60mm x 0.80mm). Vishay Dale CRCW series parts have width variations (0.033" or 0.85mm). These variations remain within 0603 package tolerance and do not affect PCB footprint compatibility.
