Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F6981V are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 6.98 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0603 (1608 Metric)
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Acceptable Variations):

• RoHS Status: ROHS3 Compliant or equivalent
• Packaging: Tape & Reel (TR)
• Composition: Thick Film

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within the 0603 package specification and differences in specific features (anti-sulfur vs. moisture resistant) do not affect functional interchangeability in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

ERJ-3EKF6981V (Panasonic) and RMCF0603FT6K98 (Stackpole Electronics Inc) are preferred substitutes. Both parts maintain ROHS3 compliance, AEC-Q200 automotive rating, and highest inventory availability (88502 and 87656 units respectively). These parts are functionally identical to the main part across all critical electrical and mechanical parameters.

RC0603FR-076K98L (YAGEO) offers the highest inventory level (335004 units) with ROHS3 compliance and moisture-resistant composition. This part is suitable for applications where supply chain continuity is prioritized.

CRCW06036K98FKEA (Vishay Dale) provides AEC-Q200 automotive rating with ROHS3 compliance and 41835 units in stock, supporting automotive-grade applications.

Secondary Substitute (Compliance Consideration):

CRCW06036K98FKTA (Vishay Dale) is functionally equivalent but carries RoHS non-compliant status and REACH Affected designation. This part should be selected only when legacy design requirements or specific supply constraints mandate its use.

Alternative Substitute (Feature Variation):

CR0603-FX-6981ELF (Bourns Inc.) features moisture-resistant composition instead of anti-sulfur properties. This part is suitable for applications requiring enhanced moisture protection in humid or corrosive environments while maintaining ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF6981V replace ERJ-S03F6981V directly?

A: Yes. Both parts share identical electrical specifications (6.98 kΩ ±1%, 0.1W, ±100ppm/°C), operate across -55°C to 155°C, use 0603 package format, and maintain ROHS3 compliance. The primary difference is the series designation (ERJ-3EK vs. ERJ-S03), which reflects manufacturing line variation within Panasonic's product portfolio. Direct substitution is functionally equivalent.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur composition (ERJ-S03F6981V) protects against sulfur-containing atmospheric contaminants common in industrial environments. Moisture-resistant composition (CR0603-FX-6981ELF, RC0603FR-076K98L) provides enhanced protection in high-humidity or wet environments. Both are thick film resistors with identical electrical performance. Feature selection depends on application environment rather than circuit function.

Q: Is CRCW06036K98FKTA suitable for new production designs?

A: CRCW06036K98FKTA is functionally equivalent but carries RoHS non-compliant and REACH Affected status. This part is not recommended for new designs targeting RoHS3 compliance or EU market distribution. Use only when legacy design requirements or specific supply constraints mandate its selection.

Q: Do all substitute parts fit the same PCB footprint?

A: All substitute parts use 0603 (1608 Metric) package format with 2 terminations. Physical dimensions vary slightly within package specification (length 0.061" to 0.063", width 0.031" to 0.033", height 0.020" to 0.022"). These variations are within standard 0603 tolerance and do not affect PCB footprint compatibility. Standard 0603 land patterns accommodate all listed parts.

Q: Which substitute offers the best supply availability?

A: RC0603FR-076K98L (YAGEO) provides the highest inventory level at 335004 units. For automotive-grade applications, ERJ-3EKF6981V (Panasonic) and RMCF0603FT6K98 (Stackpole) offer 88502 and 87656 units respectively with AEC-Q200 certification.

Q: Are all substitutes AEC-Q200 rated?

A: ERJ-3EKF6981V, CRCW06036K98FKEA, CRCW06036K98FKTA, and RMCF0603FT6K98 carry AEC-Q200 automotive rating. CR0603FR-076K98L and CR0603-FX-6981ELF do not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, select from the certified parts.
