Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3401CS is determined by strict adherence to the following parameters:

Critical Electrical Parameters (Must Match Exactly):

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters (Must Match Exactly):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts listed (CRCW12063K40FKEA, ERJ-8ENF3401V, RC1206FR-073K4L, RMCF1206FT3K40) meet these criteria. Dimensional variations within the 1206 package specification are acceptable for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW12063K40FKEA (Vishay Dale) and RMCF1206FT3K40 (Stackpole Electronics) are recommended as primary substitutes. Both parts carry Active product status, ROHS3 compliance, and AEC-Q200 automotive qualification. These parts are suitable for new designs and ongoing production applications.

RC1206FR-073K4L (YAGEO) is an Active product with equivalent electrical and mechanical specifications. This part is suitable for applications where moisture resistance is a primary design requirement.

Secondary Substitute (Legacy Applications Only):

ERJ-8ENF3401V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part is electrically and mechanically equivalent but should be used only in legacy system maintenance, repair, or replacement scenarios where design continuity is required. New designs should not incorporate this part number.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage requirements. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063K40FKEA be used as a direct replacement for RCS3216F3401CS?

A: Yes. Both parts share identical electrical specifications (3.4 kOhms ±1%, 0.25W), operate across the same temperature range (-55°C ~ 155°C), and use the 1206 package. The maximum seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances. CRCW12063K40FKEA is Active status and suitable for new designs.

Q: What is the difference between the Samsung RCS3216F3401CS and the Panasonic ERJ-8ENF3401V?

A: Electrically and mechanically, these parts are equivalent. The primary difference is product status: RCS3216F3401CS is Active, while ERJ-8ENF3401V is designated "Not For New Designs." The Panasonic part should be reserved for legacy applications only.

Q: Are all substitute parts AEC-Q200 qualified?

A: CRCW12063K40FKEA (Vishay Dale) and RMCF1206FT3K40 (Stackpole) carry AEC-Q200 automotive qualification. RC1206FR-073K4L (YAGEO) does not list AEC-Q200 qualification. ERJ-8ENF3401V (Panasonic) carries AEC-Q200 qualification but is not recommended for new designs. Select based on automotive qualification requirements.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part RCS3216F3401CS, carry MSL 1 (Unlimited) rating. This indicates unlimited shelf life under standard storage conditions and compatibility with standard PCB assembly processes.

Q: What are the dimensional differences between substitute parts?

A: All parts use the 1206 (3216 Metric) package. Length dimensions range from 0.122" to 0.126" (3.10mm to 3.20mm). Maximum seated heights range from 0.024" to 0.028" (0.60mm to 0.70mm). These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Can I mix different substitute parts in the same production run?

A: Yes, provided your design specifications do not require a single manufacturer part number. All listed substitutes meet identical electrical and mechanical criteria. However, for traceability and quality control purposes, maintaining a single part number per production batch is recommended.

Q: Which substitute has the highest inventory availability?

A: ERJ-8ENF3401V (Panasonic) has 65,631 pieces in stock. However, this part carries "Not For New Designs" status. For new designs, CRCW12063K40FKEA (Vishay Dale) has 11,469 pieces available, and RC1206FR-073K4L (YAGEO) has 23,960 pieces available.
