Engineering Selection Recommendations

RT0805BRD074K64L (YAGEO): Direct upgrade offering ±0.1% tolerance and ±25ppm/°C temperature coefficient with ROHS3 compliance. Suitable for applications requiring tighter tolerance control than the original specification.

RT0805DRE074K64L (YAGEO): Mid-tolerance option at ±0.5% with ROHS3 compliance. Maintains original temperature coefficient specification while providing improved tolerance performance.

7-2176092-6 (TE Connectivity): Offers ±0.1% tolerance and increased power rating (0.25W). Note: RoHS non-compliant status restricts use in regulated applications. Higher seated height (0.026" vs 0.024") may affect PCB layout compatibility.

ERA-6AEB4641V (Panasonic): ±0.1% tolerance with Automotive AEC-Q200 qualification and ROHS3 compliance. Suitable for automotive and high-reliability applications requiring certified component status.

RG2012P-4641-B-T5 (Susumu): ±0.1% tolerance with Anti-Sulfur coating and Automotive AEC-Q200 qualification. ROHS3 compliant. Lowest seated height (0.020") provides optimal PCB space efficiency for dense layouts.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD074K64L replace RT0805FRE074K64L directly?

A: Yes. Both components share identical resistance value (4.64 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RT0805BRD074K64L provides superior tolerance (±0.1% vs ±1%) and tighter temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between tolerance and temperature coefficient in these resistors?

A: Tolerance specifies the initial accuracy of the resistance value at 25°C (±1% means the actual value can vary by 1% from the nominal 4.64 kOhms). Temperature coefficient (ppm/°C) specifies how much the resistance changes per degree Celsius deviation from 25°C. Tighter specifications in both parameters improve circuit stability and predictability.

Q: Why does 7-2176092-6 have a higher power rating (0.25W vs 0.125W)?

A: Higher power rating indicates the component can dissipate more heat without exceeding temperature limits. This does not affect substitution compatibility if the circuit requires only 0.125W dissipation. However, the RoHS non-compliant status may restrict use in regulated markets.

Q: Are automotive-qualified parts (ERA-6AEB4641V, RG2012P-4641-B-T5) interchangeable with standard industrial parts?

A: Yes, automotive-qualified parts meet or exceed industrial specifications and are electrically and mechanically compatible. AEC-Q200 certification indicates additional qualification testing for automotive environments. Use automotive-qualified parts when application requirements or customer specifications mandate such certification.

Q: Does seated height variation affect PCB assembly?

A: Seated height differences (0.020" to 0.026") are within typical PCB assembly tolerances for 0805 components. However, in high-density layouts or applications with height constraints, verify PCB design clearances. RG2012P-4641-B-T5 (0.020" height) offers maximum clearance; 7-2176092-6 (0.026" height) requires verification.

Q: What packaging options are available?

A: RT0805FRE074K64L, RT0805BRD074K64L, RT0805DRE074K64L, 7-2176092-6, and RG2012P-4641-B-T5 are supplied in Tape & Reel (TR) format. ERA-6AEB4641V is supplied in Cut Tape (CT) & Digi-Reel® format. Confirm packaging compatibility with assembly equipment specifications.
