Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0743KL are qualified based on the following criteria:

• Identical resistance value: 43 kOhms
• Compatible package: 1206 (3216 Metric)
• Equal or greater power rating: 0.25W minimum
• Matching or superior tolerance: ±1% or better
• Thin film composition
• Operating temperature range: -55°C to 155°C minimum
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

The identified substitutes meet or exceed these parameters, enabling direct replacement in applications where the RT1206FRE0743KL is specified.

Parameter Comparison

Engineering Selection Recommendations

Both ERA-8AEB433V and RG3216P-4302-B-T5 are direct substitutes for RT1206FRE0743KL. The ERA-8AEB433V from Panasonic Electronic Components carries AEC-Q200 automotive qualification and offers improved tolerance (±0.1% versus ±1%) with a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The RG3216P-4302-B-T5 from Susumu provides identical electrical advantages with additional anti-sulfur protection and AEC-Q200 rating, making it suitable for automotive and harsh environment applications. All three parts maintain ROHS3 compliance and MSL 1 rating. Selection between substitutes depends on application-specific requirements for automotive qualification and environmental protection.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB433V replace RT1206FRE0743KL directly? A: Yes. Both parts share identical resistance (43 kOhms), power rating (0.25W), package (1206), and operating temperature range (-55°C to 155°C). ERA-8AEB433V offers superior tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it a compatible upgrade.

Q: What is the difference between the two substitute parts? A: ERA-8AEB433V and RG3216P-4302-B-T5 both provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. RG3216P-4302-B-T5 includes anti-sulfur protection and has a lower maximum seated height (0.020" versus 0.028"), which may be relevant for space-constrained applications.

Q: Are the substitute parts suitable for automotive applications? A: Both ERA-8AEB433V and RG3216P-4302-B-T5 carry AEC-Q200 automotive qualification. The original RT1206FRE0743KL does not have this rating. If automotive qualification is required, either substitute is appropriate.

Q: Do package dimensions differ between these parts? A: Length and width are slightly different. RT1206FRE0743KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm), while both substitutes measure 0.126" L × 0.063" W (3.20mm × 1.60mm). Height varies: RT1206FRE0743KL is 0.026" (0.65mm), ERA-8AEB433V is 0.028" (0.70mm), and RG3216P-4302-B-T5 is 0.020" (0.50mm). These differences are within standard 1206 package tolerances.

Q: Are all parts ROHS3 compliant? A: Yes. RT1206FRE0743KL, ERA-8AEB433V, and RG3216P-4302-B-T5 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
