Parameter Comparison

Engineering Selection Recommendations

CSRN2512FTR680 (Main Part): Select this part for applications requiring Stackpole Electronics manufacturing with AEC-Q200 automotive qualification. Suitable for current sense applications in automotive environments with standard temperature coefficient performance.

RLP73K3AR68FTDF (Direct Substitute): This TE Connectivity part provides direct electrical and mechanical equivalence with identical resistance, tolerance, power rating, and temperature coefficient. Inventory availability is higher (2925 units). Note that this part does not carry AEC-Q200 automotive qualification; use only in non-automotive applications or where automotive qualification is not required.

RCWE2512R680FKEA (Upgrade Substitute): This Vishay Dale part offers enhanced specifications with AEC-Q200 automotive qualification and moisture-resistant thick film composition. The temperature coefficient is improved to ±100ppm/°C compared to ±200ppm/°C in the main part. Height-seated dimension matches the main part at 0.028" (0.70mm). Select this part for applications requiring superior temperature stability and moisture resistance in automotive environments.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR68FTDF be used in automotive applications? A: RLP73K3AR68FTDF does not carry AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive qualification is not a requirement.

Q: What is the difference between the main part and RCWE2512R680FKEA? A: Both parts carry AEC-Q200 automotive qualification and are mechanically identical in the 2512 package. RCWE2512R680FKEA features a lower temperature coefficient (±100ppm/°C vs ±200ppm/°C) and moisture-resistant composition, providing enhanced performance in temperature-sensitive and high-humidity environments.

Q: Are all substitute parts in the same 2512 package? A: Yes, all parts listed are in the 2512 (6432 Metric) package with identical footprint and termination count. Height-seated dimensions are 0.028" (0.70mm) for CSRN2512FTR680 and RCWE2512R680FKEA, and 0.033" (0.84mm) for RLP73K3AR68FTDF. Verify clearance requirements in space-constrained designs.

Q: Do all parts meet RoHS3 compliance? A: Yes, all listed parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should I select for maximum inventory availability? A: RLP73K3AR68FTDF has the highest inventory at 2925 units. However, confirm that automotive qualification is not required before selecting this part.
