Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6191CS is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria (Must Match Exactly):

• Resistance Value: 6.19 kOhms
• Tolerance: ±1%
• Power Rating: 0.1W (1/10W)
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute Classification:

Direct Equivalents (Identical specifications across all parameters):

• CR0603-FX-6191ELF (Bourns Inc.)
• RC0603FR-076K19L (YAGEO)

Similar Parts with Enhanced Features (Meet all primary criteria; include automotive AEC-Q200 qualification):

• CRCW06036K19FKEA (Vishay Dale) – RoHS3 Compliant
• CRCW06036K19FKTA (Vishay Dale) – RoHS non-compliant, REACH Affected
• ERJ-3EKF6191V (Panasonic Electronic Components)
• RMCF0603FT6K19 (Stackpole Electronics Inc)

All substitute parts maintain identical electrical performance, thermal characteristics, and physical dimensions within specified tolerances. Automotive-qualified variants (AEC-Q200) provide additional qualification for automotive applications while maintaining full compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

For General Industrial and Consumer Applications: Select CR0603-FX-6191ELF (Bourns Inc.) or RC0603FR-076K19L (YAGEO) as primary alternatives. Both parts maintain identical specifications to the RC1608F6191CS with RoHS3 compliance and REACH unaffected status. These direct equivalents provide supply chain flexibility without design modification.

For Automotive Applications: Select ERJ-3EKF6191V (Panasonic Electronic Components) or RMCF0603FT6K19 (Stackpole Electronics Inc) for designs requiring AEC-Q200 automotive qualification. Both parts are RoHS3 compliant, REACH unaffected, and maintain full electrical and thermal equivalence. CRCW06036K19FKEA (Vishay Dale) is also automotive-qualified and RoHS3 compliant, available in Cut Tape and Digi-Reel packaging.

Packaging Considerations:

• Cut Tape (CT) packaging: RC1608F6191CS, CR0603-FX-6191ELF, RC0603FR-076K19L, CRCW06036K19FKEA
• Tape & Reel (TR) packaging: CRCW06036K19FKTA, ERJ-3EKF6191V, RMCF0603FT6K19

Compliance Status: All recommended substitutes maintain RoHS3 compliance except CRCW06036K19FKTA, which is RoHS non-compliant and REACH affected. Selection should align with end-product regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: Can I substitute RC1608F6191CS with any of the listed parts without design changes?

A: Yes. All listed substitute parts meet identical electrical specifications (6.19 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range). Physical dimensions and termination count are equivalent. No circuit design modifications are required.

Q2: What is the difference between direct equivalents and automotive-qualified substitutes?

A: Direct equivalents (CR0603-FX-6191ELF, RC0603FR-076K19L) provide identical general-purpose specifications. Automotive-qualified substitutes (ERJ-3EKF6191V, RMCF0603FT6K19, CRCW06036K19FKEA, CRCW06036K19FKTA) include AEC-Q200 certification, meeting additional automotive reliability and testing standards. Electrical performance remains identical; automotive variants are suitable for automotive applications requiring qualification documentation.

Q3: Does packaging type affect electrical performance?

A: No. Cut Tape (CT) and Tape & Reel (TR) packaging types do not affect electrical or thermal performance. Selection depends on assembly process requirements and volume handling. CT packaging is suitable for lower-volume or manual assembly; TR packaging is optimized for high-volume automated pick-and-place assembly.

Q4: Are there compliance differences between substitute parts?

A: Most substitutes are RoHS3 compliant and REACH unaffected, matching the original RC1608F6191CS. Exception: CRCW06036K19FKTA is RoHS non-compliant and REACH affected. Verify compliance requirements for your end application before selection.

Q5: What does MSL 1 (Unlimited) mean for handling?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts share this specification, allowing standard storage conditions without special humidity control or pre-reflow baking procedures.

Q6: Can I use CRCW06036K19FKTA as a substitute if my design is not automotive?

A: Electrically and thermally, yes. However, CRCW06036K19FKTA is RoHS non-compliant and REACH affected. Use only if your end-product regulatory requirements permit non-compliant components. For RoHS3-compliant designs, select alternative substitutes.

Q7: Which substitute offers the highest inventory availability?

A: RMCF0603FT6K19 (Stackpole Electronics Inc) has the highest reported inventory at 155,731 pieces. CRCW06036K19FKEA (Vishay Dale) has 38,873 pieces. Both provide reliable supply for high-volume production.
