Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE073K92L is determined by the following critical parameters: resistance value (3.92 kOhms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). All substitute parts maintain these core specifications.

Substitute parts are grouped into three categories based on tolerance and power rating enhancements:

Tolerance Upgrade (±1% to ±0.1%): RT0805BRD073K92L, ERA-6AEB3921V, RG2012P-3921-B-T5, and 6-2176092-9 provide improved tolerance specifications while maintaining the same resistance and package.

Tolerance Intermediate (±1% to ±0.5%): RT0805DRE073K92L offers mid-range tolerance improvement.

Power Rating Upgrade (1/8W to 1/4W): 6-2176092-9 provides increased power dissipation capability (0.25W) while maintaining tolerance and package compatibility.

Automotive Certification: ERA-6AEB3921V and RG2012P-3921-B-T5 include AEC-Q200 automotive qualification and anti-sulfur features for demanding environments.

Engineering Selection Recommendations

For Standard Industrial Applications: RT0805BRD073K92L provides tolerance improvement (±0.1%) and reduced temperature coefficient (±25ppm/°C) over the original specification while maintaining identical power rating and package footprint. This part is suitable for precision analog circuits requiring tighter tolerance control.

For Intermediate Tolerance Requirements: RT0805DRE073K92L offers ±0.5% tolerance as a middle-ground option between the original ±1% and premium ±0.1% specifications.

For Increased Power Dissipation: 6-2176092-9 from TE Connectivity provides doubled power rating (0.25W vs. 0.125W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part accommodates higher current applications within the same package footprint.

For Automotive Applications: ERA-6AEB3921V (Panasonic) and RG2012P-3921-B-T5 (Susumu) both carry AEC-Q200 automotive qualification. RG2012P-3921-B-T5 additionally includes anti-sulfur coating for enhanced reliability in corrosive environments. Both maintain ±0.1% tolerance and ±25ppm/°C temperature coefficient.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range, ensuring direct compatibility with the original design requirements.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD073K92L directly replace RT0805FRE073K92L?

A: Yes. Both parts share identical resistance (3.92 kOhms), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). RT0805BRD073K92L provides improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it a direct upgrade with no circuit modifications required.

Q: What is the difference between the YAGEO RT series substitutes?

A: RT0805FRE073K92L (±1%), RT0805DRE073K92L (±0.5%), and RT0805BRD073K92L (±0.1%) differ only in tolerance specification and temperature coefficient. All three are YAGEO thin film resistors in 0805 package with identical power rating and operating temperature range. Selection depends on circuit tolerance requirements.

Q: Why does 6-2176092-9 have a higher power rating?

A: 6-2176092-9 is rated for 0.25W (1/4W) compared to 0.125W (1/8W) for other parts. This higher power dissipation capability accommodates applications with greater current flow through the resistor. The part maintains the same 0805 package footprint and all other electrical specifications.

Q: Are ERA-6AEB3921V and RG2012P-3921-B-T5 suitable for non-automotive applications?

A: Yes. Both parts exceed standard industrial requirements with AEC-Q200 automotive qualification. They can be used in any application requiring ±0.1% tolerance, ±25ppm/°C temperature coefficient, and ROHS3 compliance. RG2012P-3921-B-T5 anti-sulfur coating provides additional protection in harsh environments regardless of application type.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated heights vary slightly (0.024" to 0.026"), but all remain within standard 0805 assembly tolerances and present no placement or clearance issues.

Q: What is the inventory status for substitute parts?

A: RT0805BRD073K92L: 4632 units; RT0805DRE073K92L: 983 units; 6-2176092-9: 1080 units; ERA-6AEB3921V: 15283 units; RG2012P-3921-B-T5: 9660 units. All parts are active products with new original stock available.
