RC3216F3400CS Equivalent & Substitute Parts

Part Overview

The RC3216F3400CS is a 340 Ohm ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant resistor operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3400CS is determined by strict alignment of the following parameters:

Electrical Specifications:

• Resistance value: 340 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Specifications:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance & Environmental:

• Composition: Thick Film
• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

All identified substitute parts meet these core parameters. Variations in seated height and specific feature sets (such as automotive AEC-Q200 qualification) do not preclude substitution when electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

RC3216F3400CS (Samsung Electro-Mechanics): Primary selection for new designs. Active production status with established supply chain. Moisture-resistant thick film construction suitable for general industrial applications.

CRCW1206340RFKEA (Vishay Dale): Direct electrical and mechanical equivalent with active production status. Includes automotive AEC-Q200 qualification, providing enhanced reliability for automotive and mission-critical applications. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB layouts.

ERJ-8ENF3400V (Panasonic Electronic Components): Electrical and mechanical equivalent with automotive AEC-Q200 qualification. Product status is "Not For New Designs," restricting use to legacy system maintenance and existing design support only. Seated height of 0.028" (0.70mm) remains compatible with standard 1206 package specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206340RFKEA replace RC3216F3400CS in existing designs?

A: Yes. Both parts share identical electrical specifications (340 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and mechanical dimensions (1206 package, 3.20mm x 1.60mm). Seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances.

Q: Why is ERJ-8ENF3400V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent, it is restricted to replacement and legacy support applications only. New designs should specify RC3216F3400CS or CRCW1206340RFKEA.

Q: Are there differences in moisture handling between these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels. No differential moisture protection exists between the substitutes.

Q: Does the automotive AEC-Q200 qualification on CRCW1206340RFKEA affect non-automotive applications?

A: No. AEC-Q200 qualification represents additional testing and reliability assurance. Parts meeting automotive standards are fully compatible with general industrial and consumer applications.

Q: What is the significance of the seated height variation?

A: Seated heights range from 0.024" to 0.028" across the three parts. This 0.004" variation is negligible for standard PCB assembly processes and does not affect electrical performance or mechanical fit in 1206 package footprints.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC3216F3400CS, CRCW1206340RFKEA, and ERJ-8ENF3400V are all ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.
