Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• Resistance value: 6.98 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 to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compliance Criteria:

• RoHS3 compliance status
• REACH regulatory status
• Packaging format: Tape & Reel (TR)

Substitute parts are grouped into two categories based on feature alignment:

Direct Equivalents maintain identical moisture-resistant construction without automotive qualification.

Similar Parts include automotive AEC-Q200 rated variants, which provide enhanced reliability specifications suitable for automotive and industrial applications while maintaining all primary electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: Select CR0603-FX-6981ELF (Bourns Inc.) or RC0603FR-076K98L (YAGEO) as direct equivalents. Both maintain identical moisture-resistant specifications and RoHS3 compliance with the main part RC1608F6981CS. These options provide high inventory availability and functional interchangeability.

For Automotive and Enhanced Reliability Applications: Select ERJ-3EKF6981V (Panasonic Electronic Components) or RMCF0603FT6K98 (Stackpole Electronics Inc) for AEC-Q200 automotive qualification. Both parts maintain RoHS3 compliance and all primary electrical parameters while providing automotive-grade reliability certification.

Compliance Consideration: CRCW06036K98FKTA (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is suitable only for applications where RoHS3 compliance is not required.

Dimensional Compatibility: All substitute parts are packaged in 0603 (1608 Metric) format with minor dimensional variations within acceptable PCB assembly tolerances. Height-seated maximum values range from 0.020" to 0.022" (0.50mm to 0.55mm), compatible with standard surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-076K98L replace RC1608F6981CS directly? A: Yes. RC0603FR-076K98L (YAGEO) is a direct equivalent with identical resistance, tolerance, power rating, package, temperature coefficient, operating temperature range, and moisture sensitivity level. Both are RoHS3 compliant and packaged in Tape & Reel format.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants? A: Moisture-resistant variants (CR0603-FX-6981ELF, RC0603FR-076K98L) are designed for standard industrial environments. Automotive AEC-Q200 variants (ERJ-3EKF6981V, RMCF0603FT6K98, CRCW06036K98FKEA) include additional qualification testing and reliability standards required for automotive applications. Both categories maintain identical electrical specifications.

Q: Are there inventory differences between substitute parts? A: Yes. RC0603FR-076K98L (YAGEO) has the highest inventory at 335,004 pieces. ERJ-3EKF6981V (Panasonic) has 88,502 pieces, RMCF0603FT6K98 (Stackpole) has 87,656 pieces, and CRCW06036K98FKEA (Vishay Dale) has 41,835 pieces. CR0603-FX-6981ELF (Bourns) has 22,013 pieces.

Q: Is CRCW06036K98FKTA suitable for new designs? A: CRCW06036K98FKTA is RoHS non-compliant and REACH-affected. It is not recommended for new designs requiring RoHS3 compliance. Use CRCW06036K98FKEA (RoHS3 compliant variant) instead.

Q: Do all substitute parts have the same temperature coefficient? A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, identical to the main part RC1608F6981CS.

Q: What is Moisture Sensitivity Level 1? A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All parts in this reference maintain MSL 1 classification, ensuring no special storage or handling procedures are necessary.

Q: Can automotive-rated parts be used in non-automotive applications? A: Yes. Automotive AEC-Q200 rated parts (ERJ-3EKF6981V, RMCF0603FT6K98, CRCW06036K98FKEA) exceed standard industrial specifications and are fully compatible with non-automotive applications. They provide enhanced reliability at no functional disadvantage.
