Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RC3216F3403CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 340 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W minimum
• Temperature coefficient: ±100ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) form factor
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint
• Height seated maximum: 0.026" or less preferred

Compliance & Environmental Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH unaffected status

All identified substitute parts meet these criteria. Substitute parts are further categorized by product status (Active vs. Not For New Designs) and additional certifications (Automotive AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for New Designs): RC1206FR-07340KL (YAGEO) is the preferred substitute. This component maintains Active product status, identical electrical specifications, and equivalent mechanical dimensions. YAGEO RC_L series offers high inventory availability (56,945 pcs) and full ROHS3 compliance with unlimited moisture sensitivity rating.

Secondary Substitute (Automotive Applications): CRCW1206340KFKEA (Vishay Dale) is suitable for applications requiring AEC-Q200 automotive qualification. This component provides the lowest seated height (0.024" / 0.60mm), which may be advantageous in space-constrained designs. Active product status and full compliance certifications apply.

Legacy Substitute (Not Recommended for New Designs): ERJ-8ENF3403V (Panasonic) carries "Not For New Designs" product status. While electrically and mechanically equivalent with AEC-Q200 rating, this component should be used only for replacement or maintenance of existing assemblies. The seated height (0.028" / 0.70mm) is marginally higher than other options.

All three substitute parts are electrically interchangeable with the RC3216F3403CS and support direct PCB footprint replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07340KL replace RC3216F3403CS in production assemblies? A: Yes. Both components share identical electrical specifications (340 kOhms ±1%, 0.25W), operate across -55°C to 155°C, and use 1206 package format. Mechanical dimensions are equivalent within manufacturing tolerances. ROHS3 and MSL ratings match.

Q: What is the difference between the Samsung and YAGEO versions? A: The RC3216F3403CS (Samsung) and RC1206FR-07340KL (YAGEO) are functionally equivalent. Primary differences are manufacturer, series designation (RC vs. RC_L), and packaging format. YAGEO offers higher inventory availability. Both maintain Active product status.

Q: Is CRCW1206340KFKEA suitable for automotive applications? A: Yes. CRCW1206340KFKEA carries AEC-Q200 automotive qualification. If your application requires automotive-grade components, this Vishay Dale part meets that requirement. The RC3216F3403CS does not specify automotive rating.

Q: Why is ERJ-8ENF3403V marked "Not For New Designs"? A: ERJ-8ENF3403V carries obsolescence status indicating Panasonic has discontinued active development for new applications. This component remains available for existing assembly maintenance and replacement. New designs should use RC1206FR-07340KL or CRCW1206340KFKEA.

Q: Are there dimensional compatibility concerns between these parts? A: All four components use 1206 (3216 Metric) package with 2 terminations. Seated heights range from 0.024" to 0.028", all within standard PCB design tolerances. No dimensional incompatibility exists for standard 1206 footprints.

Q: Do all substitutes maintain the same moisture resistance? A: Yes. All parts carry MSL rating 1 (Unlimited), indicating identical moisture sensitivity performance. No additional moisture protection measures are required when substituting between these components.

Q: Which substitute offers the best long-term availability? A: RC1206FR-07340KL (YAGEO) demonstrates the highest inventory level (56,945 pcs) and Active product status, indicating sustained manufacturing commitment. This part is recommended for designs requiring long-term component availability.
