Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6493CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 649 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Power Rating Consideration: Substitute parts are classified into two categories based on power rating:

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

All identified substitutes maintain identical electrical specifications, physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), and maximum seated height (0.016" / 0.40mm), ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (Identical Specifications):

CR0402-FX-6493GLF (Bourns Inc.) and RC0402FR-07649KL (YAGEO) are direct functional equivalents to the RC1005F6493CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and operating parameters. Selection between these options is based on inventory availability and supply chain logistics.

Upgrade Option (Higher Power Rating):

ERJ-2RKF6493X (Panasonic Electronic Components) provides an upgrade path with increased power rating of 0.1W (1/10W) versus the standard 0.063W. This component carries Automotive AEC-Q200 certification and is backward compatible for applications where the original 1/16W specification is not a limiting constraint.

Automotive-Qualified Alternatives:

CRCW0402649KFKED (Vishay Dale) and RMCF0402FT649K (Stackpole Electronics Inc) are functionally equivalent to the main part with the addition of Automotive AEC-Q200 qualification. These components are suitable for applications requiring automotive-grade reliability standards while maintaining identical electrical and mechanical specifications.

All substitute parts are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and maintain Active product status.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6493GLF be used as a direct replacement for RC1005F6493CS?

A: Yes. CR0402-FX-6493GLF is a direct equivalent substitute. Both components share identical resistance (649 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Q: What is the difference between the main part and ERJ-2RKF6493X?

A: ERJ-2RKF6493X differs in power rating (0.1W versus 0.063W) and includes Automotive AEC-Q200 certification. All other electrical parameters and package dimensions remain identical. The higher power rating makes this component suitable for applications with greater thermal dissipation requirements.

Q: Are CRCW0402649KFKED and RMCF0402FT649K suitable for non-automotive applications?

A: Yes. Both components are functionally equivalent to RC1005F6493CS and can be used in non-automotive applications. The Automotive AEC-Q200 certification indicates enhanced reliability qualification but does not restrict use in general industrial or consumer applications.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All listed substitute parts conform to the 0402 (1005 Metric) package standard with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable in PCB layouts designed for the RC1005F6493CS.

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

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored indefinitely without requiring special moisture-controlled packaging or baking procedures prior to soldering, simplifying inventory management and assembly processes.

Q: Can RC0402FR-07649KL replace RC1005F6493CS in moisture-sensitive applications?

A: Yes. RC0402FR-07649KL includes moisture-resistant construction identical to the main part and carries the same MSL rating of 1 (Unlimited). Both components are suitable for applications requiring moisture resistance.
