Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE074K32L is determined by the following critical parameters:

• Resistance Value: Must be 4.32 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Tolerance, power rating, temperature coefficient, and feature certifications (such as AEC-Q200) may vary between substitute parts while maintaining functional equivalence. The identified substitutes meet all critical parameters and are suitable for direct replacement in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

ERA-8AEB4321V (Panasonic): This substitute offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). It includes AEC-Q200 automotive qualification, making it suitable for applications requiring enhanced precision and automotive-grade reliability. Physical dimensions are slightly larger (3.20mm L × 1.60mm W versus 3.10mm L × 1.60mm W), which must be verified against PCB layout constraints.

RNCF1206BKC4K32 (Stackpole Electronics): This manufacturer-recommended substitute provides improved tolerance (±0.1%) and higher power rating (0.333W versus 0.25W). AEC-Q200 automotive qualification is included. Physical dimensions are comparable to the main part (3.05mm L × 1.55mm W). The increased power rating provides additional thermal margin in applications subject to sustained current flow.

Both substitutes maintain full compatibility with the 1206 package footprint and operating temperature range. Selection between substitutes depends on specific application requirements regarding tolerance precision, power dissipation, and automotive compliance certification.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4321V be used as a direct replacement for RT1206FRE074K32L?

A: Yes. Both components share identical resistance value (4.32 kOhms), package (1206), composition (thin film), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB4321V offers superior tolerance and temperature coefficient specifications. Physical dimensions differ slightly; verify PCB layout clearance before substitution.

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

A: ERA-8AEB4321V (Panasonic) features ±0.1% tolerance and ±25ppm/°C temperature coefficient with 0.25W power rating. RNCF1206BKC4K32 (Stackpole) features ±0.1% tolerance and ±50ppm/°C temperature coefficient with 0.333W power rating. Both include AEC-Q200 automotive qualification. Selection depends on precision requirements and thermal dissipation needs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part and both substitutes are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All components are suitable for lead-free soldering processes.

Q: Do the substitute parts fit the same PCB footprint?

A: All parts use the 1206 (3216 Metric) package. Physical dimensions vary slightly: RT1206FRE074K32L (3.10mm L × 1.60mm W), ERA-8AEB4321V (3.20mm L × 1.60mm W), RNCF1206BKC4K32 (3.05mm L × 1.55mm W). Verify PCB layout and clearance specifications before substitution.

Q: Which substitute is recommended for automotive applications?

A: Both ERA-8AEB4321V and RNCF1206BKC4K32 carry AEC-Q200 automotive qualification. The main part RT1206FRE074K32L does not include this certification. For automotive applications, either substitute is appropriate based on tolerance and power rating requirements.
