Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE07442KL are qualified based on the following criteria:

• Identical resistance value: 442 kOhms
• Identical package: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The identified substitutes maintain all core electrical and mechanical parameters. Differences exist in tolerance specifications and additional certifications, which represent upgrades or enhanced feature sets rather than functional deviations.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8AEB4423V and RG3216P-4423-B-T5 are direct substitutes for RT1206FRE07442KL. Selection between these options depends on application requirements:

ERA-8AEB4423V (Panasonic) provides improved tolerance (±0.1% versus ±1%) and automotive AEC-Q200 qualification. This part is suitable for applications requiring higher precision and automotive-grade reliability.

RG3216P-4423-B-T5 (Susumu) offers the same tolerance improvement and AEC-Q200 qualification with the additional feature of anti-sulfur construction. This part is recommended for environments with potential sulfur exposure or applications requiring enhanced corrosion resistance.

All three parts maintain identical RoHS3 compliance, MSL ratings, and operating temperature specifications. The choice between substitutes should be based on specific application requirements for tolerance, automotive qualification, and environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4423V or RG3216P-4423-B-T5 be used as direct replacements for RT1206FRE07442KL?

A: Yes. Both substitute parts maintain identical resistance values, power ratings, package dimensions, and operating temperature ranges. They are electrically and mechanically compatible with the original part.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance specifies the maximum deviation from the nominal resistance value. The RT1206FRE07442KL allows ±1% deviation (±4.42 kOhms), while ERA-8AEB4423V and RG3216P-4423-B-T5 allow ±0.1% deviation (±0.442 kOhms). Tighter tolerance provides higher precision for applications sensitive to resistance variation.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies components for use in automotive applications. Both substitute parts meet this standard, making them suitable for automotive-grade designs.

Q: What is the advantage of anti-sulfur construction in RG3216P-4423-B-T5?

A: Anti-sulfur construction protects the component from corrosion caused by sulfur-containing environments. This feature is beneficial in industrial or harsh environmental applications where sulfur exposure is a concern.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE07442KL, ERA-8AEB4423V, and RG3216P-4423-B-T5 are all ROHS3 compliant and have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the temperature coefficient difference between the parts?

A: RT1206FRE07442KL has a temperature coefficient of ±50ppm/°C, while both substitute parts have ±25ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations, which is advantageous for precision applications.
