RT0805FRE078K45L Equivalent & Substitute Parts

Part Overview

The RT0805FRE078K45L is an 8.45 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate enhanced performance characteristics such as improved tolerance or higher power ratings.

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE078K45L are qualified based on the following criteria:

• Resistance Value: All substitutes maintain 8.45 kOhms nominal resistance
• Package Compatibility: All substitutes use 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W)
• Composition: All substitutes are thin film resistors
• Operating Temperature Range: All substitutes support -55°C to 155°C operation
• Termination Count: All substitutes feature 2 terminations
• Tolerance Enhancement: Substitute parts offer ±0.1% tolerance (improved from ±1%)
• Temperature Coefficient: Substitute parts feature ±25ppm/°C (improved from ±50ppm/°C)

Substitutes are grouped into two categories: direct equivalents with identical power ratings and upgraded alternatives with enhanced power ratings or automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD078K45L (YAGEO): This upgrade substitute offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. ROHS3 compliance is retained. This part is suitable for applications requiring enhanced precision without increased power dissipation requirements.

9-2176092-7 (TE Connectivity): This direct substitute provides higher power rating (0.25W vs 0.125W) with improved tolerance and temperature coefficient. The part is RoHS non-compliant, which may restrict use in regulated applications. Height-seated maximum is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the main part. This substitute is applicable for designs requiring increased power handling capability in non-regulated environments.

ERA-6AEB8451V (Panasonic): This upgrade substitute combines improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) with AEC-Q200 automotive qualification. ROHS3 compliance is maintained. This part is designated for automotive applications or designs requiring automotive-grade reliability standards.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD078K45L be used as a direct replacement for RT0805FRE078K45L?

A: Yes. Both parts share identical resistance value (8.45 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C to 155°C). The RT0805BRD078K45L offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a compatible upgrade with enhanced performance characteristics.

Q: Is 9-2176092-7 footprint-compatible with the main part?

A: Yes. The 9-2176092-7 uses the same 0805 (2012 Metric) package with identical length and width dimensions (0.079" L x 0.049" W). The seated height maximum differs slightly (0.026" vs 0.024"), which does not affect PCB footprint compatibility for standard 0805 designs.

Q: What is the primary difference between RT0805BRD078K45L and ERA-6AEB8451V?

A: Both parts offer identical electrical specifications (8.45 kOhms, ±0.1% tolerance, 0.125W power rating, ±25ppm/°C temperature coefficient). The ERA-6AEB8451V includes AEC-Q200 automotive qualification, making it suitable for automotive applications. Both are ROHS3 compliant.

Q: Why is 9-2176092-7 marked as RoHS non-compliant?

A: The 9-2176092-7 does not meet ROHS3 compliance requirements. This restriction applies to applications subject to RoHS regulations. For RoHS-compliant designs, use RT0805BRD078K45L or ERA-6AEB8451V.

Q: Can 9-2176092-7 be used in applications requiring only 0.125W power dissipation?

A: Yes. The 9-2176092-7 is rated for 0.25W (1/4W) power dissipation, which exceeds the 0.125W requirement of the main part. Operating the part below its rated power specification does not create functional or reliability issues.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, consistent with the main part packaging format.
