Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603FRE07237KL is determined by the following critical parameters:

• Resistance Value: Must be 237 kOhms
• Package / Case: Must be 0603 (1608 Metric)
• Power Rating: Must be 0.1W (1/10W) minimum
• Composition: Thin film construction
• Operating Temperature Range: Must support -55°C ~ 155°C
• Termination Count: 2 terminations required

Tolerance, temperature coefficient, and automotive qualification are secondary parameters that define upgrade or downgrade relationships. Parts meeting all critical parameters are electrically and mechanically compatible for direct substitution in PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

RT0603DRE07237KL is a direct upgrade from the main part, offering improved tolerance (±0.5% vs ±1%) while maintaining identical package, power rating, and temperature range. Both parts are YAGEO products with active status and full ROHS3 compliance. Selection of this upgrade is appropriate when tighter resistance tolerance is required without introducing supplier or qualification changes.

ERA-3AEB2373V provides the highest tolerance specification (±0.1%) and lowest temperature coefficient (±25ppm/°C vs ±50ppm/°C). This Panasonic part carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring enhanced reliability and traceability. All three parts maintain identical mechanical compatibility and operating temperature range.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring equivalent environmental and moisture protection characteristics.

Frequently Asked Questions (FAQ)

Q: Can RT0603DRE07237KL replace RT0603FRE07237KL in existing designs?

A: Yes. Both parts share identical resistance value, package (0603), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). The RT0603DRE07237KL offers improved tolerance (±0.5%) with no mechanical or thermal differences. PCB layout and footprint compatibility is guaranteed.

Q: What is the primary difference between these three parts?

A: Tolerance and temperature coefficient vary across the three parts. RT0603FRE07237KL specifies ±1% tolerance with ±50ppm/°C coefficient. RT0603DRE07237KL improves to ±0.5% tolerance. ERA-3AEB2373V provides the tightest tolerance (±0.1%) and lowest temperature coefficient (±25ppm/°C), plus AEC-Q200 automotive qualification.

Q: Is ERA-3AEB2373V suitable for automotive applications?

A: Yes. ERA-3AEB2373V carries AEC-Q200 qualification, meeting automotive industry reliability and traceability requirements. The other two parts do not carry automotive qualification.

Q: Are all three parts available in the same packaging format?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging with 0603 (1608 Metric) case size, 0.063" L x 0.031" W (1.60mm x 0.80mm) dimensions, and 0.022" (0.55mm) maximum seated height.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts.
