Key Parameters

Substitute Part Grouping Explanation

Substitution for the RL3264R-R820-F is based on matching the following electrical and mechanical parameters: resistance value (820 mOhms), tolerance (±1%), power rating (1W), package size (2512 / 6432 Metric), and current sense functionality. The identified substitute ERJ-1TRQFR82U from Panasonic Electronic Components matches these core parameters. The substitute uses thick film composition instead of thin film, which affects the temperature coefficient. The ERJ-1TRQFR82U offers ±200ppm/°C temperature coefficient compared to the original 0/+100ppm/°C. The substitute provides extended operating temperature range (-55°C ~ 155°C) and includes AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-1TRQFR82U presents an active production alternative to the obsolete RL3264R-R820-F. Both parts maintain ROHS3 compliance and REACH unaffected status. The ERJ-1TRQFR82U carries AEC-Q200 automotive qualification, extending its applicability to automotive environments. The substitute demonstrates significantly higher inventory availability (27609 pieces vs 954 pieces) and is supplied in tape and reel packaging. Both components share identical package dimensions (6.40mm x 3.20mm) with minimal height difference (0.65mm vs 0.70mm). Both maintain MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between RL3264R-R820-F and ERJ-1TRQFR82U?
A: The RL3264R-R820-F uses thin film composition with 0/+100ppm/°C temperature coefficient, while ERJ-1TRQFR82U uses thick film composition with ±200ppm/°C temperature coefficient. The ERJ-1TRQFR82U includes AEC-Q200 automotive qualification.

Q: Are the package dimensions identical?
A: Yes. Both parts use 2512 (6432 Metric) package with 0.252" L x 0.126" W dimensions. The ERJ-1TRQFR82U has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.65mm) for the RL3264R-R820-F.

Q: What determines substitution compatibility for current sense resistors?
A: Substitution is based on matching resistance value (820 mOhms), tolerance (±1%), power rating (1W), package size (2512), and current sense functionality. Temperature coefficient and operating temperature range are additional factors based on circuit requirements.

Q: Why is the RL3264R-R820-F obsolete?
A: The product status indicates obsolescence by the manufacturer Susumu. This status requires identification of active production alternatives for continued supply.

Q: Does the ERJ-1TRQFR82U meet the same compliance standards?
A: Yes. Both parts are ROHS3 compliant and REACH unaffected. The ERJ-1TRQFR82U additionally meets AEC-Q200 automotive standards.

Q: What is the temperature coefficient impact?
A: The RL3264R-R820-F specifies 0/+100ppm/°C while the ERJ-1TRQFR82U specifies ±200ppm/°C. The difference in temperature coefficient affects resistance value stability across the operating temperature range.
