Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0751KL are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same 51 kOhms resistance value and 0.25W power rating. Operating temperature range (-55°C ~ 155°C) is identical across all candidates.

Mechanical Compatibility: All substitute parts use the 1206 (3216 Metric) package format with 2 terminations, ensuring PCB footprint compatibility.

Tolerance Variations: Substitute parts offer tighter tolerance specifications (±0.1% or ±0.5%) compared to the main part (±1%), representing performance upgrades rather than functional changes.

Temperature Coefficient: Substitute parts maintain temperature coefficients of ±25ppm/°C or ±50ppm/°C, both acceptable within the operating range.

Packaging Format: The main part is supplied in Cut Tape (CT) & Digi-Reel format, while substitute parts are available in Tape & Reel (TR) format, affecting procurement and assembly workflows.

Compliance & Certifications: All parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. ERA-8AEB513V includes AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0751KL replace RT1206FRE0751KL in my circuit? A: Yes. Both parts share identical resistance (51 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). The RT1206BRD0751KL offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct electrical and mechanical substitute.

Q: What is the difference between RT1206DRD0751KL and RT1206DRE0751KL? A: Both parts share ±0.5% tolerance and 0.25W power rating in 1206 package. The primary difference is temperature coefficient: RT1206DRD0751KL operates at ±25ppm/°C while RT1206DRE0751KL operates at ±50ppm/°C. Select based on temperature stability requirements for your application.

Q: Why would I choose ERA-8AEB513V over YAGEO alternatives? A: ERA-8AEB513V is qualified to AEC-Q200 automotive standards and manufactured by Panasonic. Select this part for automotive applications, safety-critical systems, or where automotive-grade component reliability is specified. It offers ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are there packaging format differences I should consider? A: The main part (RT1206FRE0751KL) is supplied in Cut Tape (CT) & Digi-Reel format, while all substitute parts are supplied in Tape & Reel (TR) format. This affects procurement, storage, and automated assembly processes. Verify your assembly equipment compatibility with Tape & Reel format before substitution.

Q: Do all substitute parts maintain the same moisture sensitivity level? A: Yes. All parts, including the main part and all substitutes, maintain MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use ERA-8AEB513V in non-automotive applications? A: Yes. ERA-8AEB513V meets all electrical and mechanical requirements for general-purpose applications. Its AEC-Q200 qualification represents an additional quality assurance level, making it suitable for any application requiring the specified 51 kOhms ±0.1% 0.25W 1206 resistor.
