Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F6342CS are qualified based on the following criteria:

Primary Substitution Criteria:

• Resistance value: 63.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Considerations:

• Power rating (0.25W minimum required; higher ratings acceptable for derating applications)
• Manufacturer certifications (AEC-Q200 automotive qualification where applicable)
• Product status (Active preferred; Not For New Designs noted where applicable)
• Physical dimensions (minor variations within tolerance acceptable)

All substitute parts listed maintain electrical and mechanical compatibility with the RCS3216F6342CS within standard PCB assembly and soldering processes.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for New Designs):

CRCW120663K4FKEA (Vishay Dale) and RC1206FR-0763K4L (YAGEO) are direct functional equivalents to the RCS3216F6342CS. Both parts maintain identical electrical specifications, package dimensions, and compliance certifications. CRCW120663K4FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications requiring enhanced reliability. RC1206FR-0763K4L provides moisture-resistant thick film construction matching the original part's environmental protection features.

Higher Power Rating Alternative:

CRCW120663K4FKEAHP (Vishay Dale) provides the same electrical specifications as the RCS3216F6342CS but with increased power rating of 0.75W (3/4W) instead of 0.25W (1/4W). This part is suitable for applications requiring additional thermal margin or pulse withstanding capability. The higher power rating does not affect circuit functionality but provides enhanced reliability in high-stress environments. AEC-Q200 automotive certification is included.

Legacy Part (Not Recommended for New Designs):

ERJ-8ENF6342V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part should be used only for replacement or repair of existing assemblies where design continuity is required. For new circuit designs, select from Active status alternatives listed above.

Selection Criteria by Application:

• Standard applications: CRCW120663K4FKEA or RC1206FR-0763K4L
• Automotive/industrial with enhanced reliability: CRCW120663K4FKEA (AEC-Q200 certified)
• High-stress or pulse applications: CRCW120663K4FKEAHP (0.75W rating with pulse withstanding)
• Existing design maintenance: ERJ-8ENF6342V (legacy compatibility only)

Frequently Asked Questions (FAQ)

Q: Can CRCW120663K4FKEAHP (0.75W) be used as a direct replacement for RCS3216F6342CS (0.25W)?

A: Yes. The higher power rating of CRCW120663K4FKEAHP is fully compatible with circuits designed for 0.25W resistors. The increased power rating provides additional thermal capacity and does not affect electrical performance. All other specifications (resistance, tolerance, package, temperature coefficient, operating range) are identical.

Q: What is the difference between CRCW120663K4FKEA and CRCW120663K4FKEAHP?

A: The primary difference is power rating: CRCW120663K4FKEA is rated 0.25W (1/4W), while CRCW120663K4FKEAHP is rated 0.75W (3/4W) with pulse withstanding capability. Both share identical resistance, tolerance, package, and temperature specifications. Selection depends on circuit power dissipation requirements.

Q: Why is ERJ-8ENF6342V marked "Not For New Designs"?

A: This designation indicates the part is in legacy status and Panasonic does not recommend it for new circuit designs. However, it remains electrically and mechanically equivalent for replacement applications in existing assemblies. For new designs, select from Active status alternatives.

Q: Are all substitute parts 1206 package compatible with the original RCS3216F6342CS?

A: Yes. All listed substitute parts use the 1206 (3216 Metric) package with identical footprint and soldering requirements. Physical dimensions vary slightly (height range 0.024" to 0.028"), but these variations are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: Does the RCS3216F6342CS require AEC-Q200 certification for automotive applications?

A: The RCS3216F6342CS does not specify AEC-Q200 certification. For automotive applications requiring AEC-Q200 qualification, use CRCW120663K4FKEA or CRCW120663K4FKEAHP (both Vishay Dale) or ERJ-8ENF6342V (Panasonic), all of which carry AEC-Q200 automotive certification.

Q: What is MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts share this MSL 1 rating, ensuring equivalent moisture resistance and storage stability.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts maintain identical 1206 package footprints, electrical specifications (63.4 kOhms ±1%, ±100ppm/°C, -55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). Direct PCB layout changes are not required for substitution.
