Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE073K4L is determined by the following core parameters:

• Resistance Value: Must be 3.4 kOhms
• Package Type: Must be 1206 (3216 Metric)
• Composition: Must be thin film
• Operating Temperature Range: Must support -55°C to 155°C minimum
• RoHS Compliance: Must meet ROHS3 standard
• MSL Rating: Must be MSL 1 or equivalent

Substitute parts may vary in tolerance (±0.1% to ±0.25%), power rating (0.25W to 0.333W), temperature coefficient, and automotive certifications without affecting functional compatibility in standard applications. Physical dimensions may have minor variations within the 1206 package specification.

Parameter Comparison

Engineering Selection Recommendations

ERA-8AEB3401V (Panasonic) is classified as an upgrade substitute. This part maintains identical resistance, power rating, and package specifications while offering improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). The component carries AEC-Q200 automotive qualification, making it suitable for applications requiring enhanced precision and automotive-grade reliability. Selection is appropriate when design specifications demand tighter tolerance control or automotive compliance.

RNCF1206CKC3K40 (Stackpole Electronics) is the manufacturer-recommended substitute. This part provides identical resistance and package with improved tolerance (±0.25%) and higher power rating (0.333W vs 0.25W). AEC-Q200 certification qualifies this component for automotive applications. The increased power dissipation capability offers design margin in thermal-constrained environments. Selection is appropriate for applications requiring higher power handling or automotive-grade components.

Both substitute parts maintain full compatibility with the original RT1206FRE073K4L in standard circuit applications while offering enhanced performance characteristics and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3401V replace RT1206FRE073K4L in any application?

A: Yes. ERA-8AEB3401V is electrically and mechanically compatible. The improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) provide enhanced performance. Physical dimensions remain within 1206 package specification. AEC-Q200 certification adds automotive-grade reliability.

Q: What is the primary difference between the two substitute parts?

A: ERA-8AEB3401V emphasizes precision with ±0.1% tolerance and ±25ppm/°C temperature coefficient. RNCF1206CKC3K40 emphasizes power handling with 0.333W rating and ±0.25% tolerance. Both carry AEC-Q200 certification. Selection depends on whether precision or power margin is the design priority.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within 1206 package specification. RT1206FRE073K4L: 3.10mm L × 1.60mm W × 0.65mm H. ERA-8AEB3401V: 3.20mm L × 1.60mm W × 0.70mm H. RNCF1206CKC3K40: 3.05mm L × 1.55mm W × 0.65mm H. All dimensions remain within standard 1206 footprint tolerances for PCB compatibility.

Q: Do substitute parts require design re-qualification?

A: Substitution within the specified parameters does not require design changes. All parts share identical resistance, package type, composition, operating temperature range, and compliance certifications. Component-level testing may be required per your quality assurance procedures.

Q: Which substitute is recommended for automotive applications?

A: Both ERA-8AEB3401V and RNCF1206CKC3K40 carry AEC-Q200 certification. ERA-8AEB3401V is preferred for precision-critical automotive circuits. RNCF1206CKC3K40 is preferred for power-constrained automotive applications.

Q: What is the moisture sensitivity level (MSL) for all parts?

A: All three parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection. No special storage or handling precautions are required beyond standard component handling practices.
