Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6493CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 649 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitution. Product status and specific feature certifications (such as AEC-Q200 automotive qualification) are noted for application-specific selection but do not prevent substitution in non-restricted applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW1206649KFKEA (Vishay Dale) and RC1206FR-07649KL (YAGEO) are recommended as primary substitutes. Both components maintain Active product status, ensuring continued availability and manufacturing support. CRCW1206649KFKEA includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07649KL provides moisture-resistant characteristics aligned with the original component specification.

Secondary Substitute (Legacy Status):

ERJ-8ENF6493V (Panasonic Electronic Components) is classified as Not For New Designs. This component meets all electrical and mechanical substitution criteria and carries AEC-Q200 automotive qualification. Selection of this part is appropriate for replacement in existing designs or maintenance applications where new design constraints do not apply.

Compliance Considerations:

All substitute parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), matching the original component's environmental and regulatory compliance profile. REACH status is Unaffected for all parts, and ECCN classification is EAR99 across all options.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206649KFKEA replace RCS3216F6493CS in any application?

A: Yes. Both components share identical electrical specifications (649 kOhms ±1%, 0.25W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in 1206 (3216 Metric) format. Physical height variation (0.024" versus 0.026") is within standard PCB assembly tolerances and does not affect functionality.

Q: What is the difference between the Samsung and Vishay parts?

A: The primary difference is feature certification. CRCW1206649KFKEA includes AEC-Q200 automotive qualification, while RCS3216F6493CS emphasizes anti-sulfur and moisture-resistant characteristics. Both are ROHS3 compliant and functionally equivalent for standard applications.

Q: Why is ERJ-8ENF6493V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has classified this part as legacy. The component remains functionally equivalent and suitable for replacement in existing designs or maintenance scenarios. New product development should prioritize parts with Active status (CRCW1206649KFKEA or RC1206FR-07649KL).

Q: Are there packaging format differences between these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format. The original RCS3216F6493CS packaging format is not specified in the provided data. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), have REACH Unaffected status, and are classified as EAR99 under ECCN. Compliance profiles are identical across all options.

Q: Can I use ERJ-8ENF6493V in a new design?

A: While ERJ-8ENF6493V is electrically and mechanically equivalent, its "Not For New Designs" status indicates manufacturer recommendation against new design implementation. CRCW1206649KFKEA or RC1206FR-07649KL are preferred for new product development.
