Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter compatibility:

Upgrade Substitutes (Direct Electrical Equivalents): Parts CPF0402B82R5E1, ERA-2AEB82R5X, RG1005P-82R5-B-T5, and RN73C1E82R5BTDF maintain the same 82.5 Ohm resistance value and 0402 package. These parts feature improved tolerance (±0.1% versus ±1%) and lower temperature coefficients (±10ppm/°C to ±25ppm/°C versus ±50ppm/°C). All operate within the same temperature range (-55°C to 155°C) and meet ROHS3 compliance.

Manufacturer Recommended Substitute (Functional Equivalent): Part ERJ-2RKF82R5X maintains 82.5 Ohm resistance and 0402 package but differs in composition (thick film versus thin film), power rating (0.1W versus 0.063W), and temperature coefficient (±100ppm/°C). This part is recommended by the manufacturer for applications where higher power dissipation is acceptable.

All substitutes share identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), two terminations, and MSL rating of 1.

Engineering Selection Recommendations

For Direct Replacement: CPF0402B82R5E1, ERA-2AEB82R5X, RG1005P-82R5-B-T5, and RN73C1E82R5BTDF are electrically superior to the RT0402FRE0782R5L due to tighter tolerance (±0.1%) and lower temperature coefficients. These parts are suitable for precision applications requiring improved stability. All four maintain thin film composition and identical power rating. Selection among these four depends on specific application requirements: ERA-2AEB82R5X and RG1005P-82R5-B-T5 include AEC-Q200 automotive qualification; RN73C1E82R5BTDF offers the lowest temperature coefficient (±10ppm/°C).

For Applications Requiring Higher Power Dissipation: ERJ-2RKF82R5X provides 0.1W power rating versus 0.063W of the original part. This part uses thick film composition and carries AEC-Q200 automotive qualification. Temperature coefficient is ±100ppm/°C, which is higher than the original specification.

All substitute parts maintain ROHS3 compliance, MSL rating of 1, and identical package footprint for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use ERA-2AEB82R5X as a direct replacement for RT0402FRE0782R5L? A: Yes. Both parts have 82.5 Ohm resistance, ±0.1% tolerance (tighter than the original ±1%), identical 0402 package dimensions, and matching operating temperature range. ERA-2AEB82R5X offers improved stability with ±25ppm/°C temperature coefficient.

Q: What is the difference between thin film and thick film composition in these resistors? A: Thin film resistors (RT0402FRE0782R5L, CPF0402B82R5E1, ERA-2AEB82R5X, RG1005P-82R5-B-T5, RN73C1E82R5BTDF) provide tighter tolerance and lower temperature coefficients. Thick film resistors (ERJ-2RKF82R5X) typically offer higher power ratings and lower cost. Composition affects stability and thermal performance but not package compatibility.

Q: Is RN73C1E82R5BTDF compatible with my existing PCB design? A: Yes. RN73C1E82R5BTDF has identical package dimensions (0.039" L x 0.020" W), two terminations, and footprint to RT0402FRE0782R5L. It is a direct mechanical and electrical substitute with superior temperature coefficient performance (±10ppm/°C).

Q: Can I use ERJ-2RKF82R5X in place of RT0402FRE0782R5L? A: ERJ-2RKF82R5X is mechanically compatible (same 0402 package) but differs electrically: it has 0.1W power rating (versus 0.063W), thick film composition (versus thin film), and ±100ppm/°C temperature coefficient (versus ±50ppm/°C). Use this part only if your circuit can tolerate these electrical differences and requires higher power dissipation capability.

Q: Which substitute offers the best temperature stability? A: RN73C1E82R5BTDF provides the lowest temperature coefficient at ±10ppm/°C, followed by CPF0402B82R5E1, ERA-2AEB82R5X, and RG1005P-82R5-B-T5 at ±25ppm/°C. The original RT0402FRE0782R5L has ±50ppm/°C.

Q: Are all these parts automotive qualified? A: ERA-2AEB82R5X and RG1005P-82R5-B-T5 carry AEC-Q200 automotive qualification. ERJ-2RKF82R5X also carries AEC-Q200. CPF0402B82R5E1 and RN73C1E82R5BTDF do not list automotive qualification in their specifications.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts share this rating.
