Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6191CS is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

• Resistance value: 6.19 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C

Core Mechanical Parameters (Non-Negotiable):

• Package / Case: 0402 (1005 Metric)
• Physical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm)
• Number of terminations: 2
• Composition: Thick Film

Compliance & Environmental Parameters:

• RoHS Status: ROHS3 Compliant (preferred)
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected (preferred)

Power Rating Consideration: Substitute parts are grouped into two categories based on power dissipation:

• Direct Equivalents: 0.063W (1/16W) rating
• Upgrade Options: 0.1W (1/10W) rating (higher power capability, backward compatible)

All identified substitutes maintain identical electrical specifications, package geometry, and environmental ratings unless explicitly noted as upgrades or automotive-qualified variants.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Standard Applications):

CR0402-FX-6191GLF (Bourns Inc.) and RC0402FR-076K19L (YAGEO) are direct functional equivalents to the RC1005F6191CS. Both maintain identical electrical and mechanical specifications with ROHS3 compliance and MSL 1 rating. RC0402FR-076K19L includes moisture resistant construction matching the original part specification.

Automotive-Qualified Alternatives:

AC0402FR-076K19L (YAGEO), CRCW04026K19FKED (Vishay Dale), and RMCF0402FT6K19 (Stackpole Electronics Inc) are AEC-Q200 automotive-qualified variants. These parts are suitable for applications requiring automotive-grade reliability and traceability. All three maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. AC0402FR-076K19L additionally includes moisture resistant construction.

Upgrade Option (Higher Power Capability):

ERJ-2RKF6191X (Panasonic Electronic Components) provides increased power dissipation at 0.1W (1/10W) versus the standard 0.063W rating. This part is AEC-Q200 qualified and ROHS3 compliant. The higher power rating enables use in applications with greater thermal stress while maintaining all other electrical and mechanical compatibility.

Compliance Consideration:

CRCW04026K19FKTD (Vishay Dale) is RoHS non-compliant and REACH affected. This part is suitable only for applications where RoHS exemptions apply or legacy system support is required.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1005F6191CS with any of the listed parts without circuit redesign?

A: Yes, all direct equivalent parts (CR0402-FX-6191GLF, RC0402FR-076K19L, AC0402FR-076K19L, CRCW04026K19FKED, RMCF0402FT6K19) are electrically and mechanically interchangeable. The upgrade option ERJ-2RKF6191X is also compatible due to backward compatibility of higher power ratings. CRCW04026K19FKTD is compatible but requires RoHS compliance verification for your application.

Q: What is the difference between direct equivalents and automotive-qualified parts?

A: Direct equivalents (CR0402-FX-6191GLF, RC0402FR-076K19L) meet standard industrial specifications. Automotive-qualified parts (AC0402FR-076K19L, CRCW04026K19FKED, RMCF0402FT6K19, ERJ-2RKF6191X) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. Automotive-qualified parts are required for automotive applications but are suitable for any application.

Q: Does moisture resistance matter for my application?

A: The original RC1005F6191CS includes moisture resistant construction. RC0402FR-076K19L and AC0402FR-076K19L also provide this feature. Other substitutes do not explicitly specify moisture resistance. For applications in high-humidity or corrosive environments, moisture-resistant variants are recommended.

Q: Can I use ERJ-2RKF6191X as a drop-in replacement?

A: Yes. ERJ-2RKF6191X has higher power rating (0.1W vs. 0.063W) but is fully backward compatible. The higher power capability does not negatively affect circuit operation in applications designed for 0.063W parts. This upgrade is beneficial for applications operating near thermal limits.

Q: What is MSL 1 rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed substitutes carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are all substitutes ROHS3 compliant?

A: Seven of eight substitutes are ROHS3 compliant. CRCW04026K19FKTD is RoHS non-compliant. Verify RoHS compliance requirements for your application before selecting this part.

Q: What is the physical height difference between parts?

A: AC0402FR-076K19L has maximum seated height of 0.015" (0.37mm), while all other parts specify 0.016" (0.40mm). This 0.001" difference is negligible for standard PCB assembly and does not affect interchangeability.
