Substitute Part Grouping Explanation

The ERA-6AEB8453V from Panasonic Electronic Components qualifies as a direct substitute for the RT0805FRE07845KL based on the following critical parameters:

• Resistance Value: Both parts specify 845 kOhms, ensuring identical electrical function
• Package Format: Both use 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.024", 0.60mm)
• Power Rating: Both rated at 0.125W (1/8W)
• Composition: Both are thin film resistors
• Operating Temperature Range: Both operate from -55°C to 155°C
• Termination Count: Both have 2 terminations
• Compliance: Both are ROHS3 compliant with MSL 1 rating

The ERA-6AEB8453V represents an upgrade option with improved tolerance (±0.1% versus ±1%) and enhanced temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), along with automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE07845KL and ERA-6AEB8453V are active products with ROHS3 compliance and MSL 1 ratings, confirming their suitability for current production environments. The ERA-6AEB8453V provides enhanced performance characteristics through tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it suitable for applications requiring higher precision. The inclusion of AEC-Q200 automotive qualification on the ERA-6AEB8453V designates it for automotive-grade applications. Selection between these parts depends on application-specific precision requirements and automotive compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB8453V directly replace the RT0805FRE07845KL in existing designs?

A: Yes. Both parts share identical resistance value (845 kOhms), power rating (0.125W), package format (0805), and operating temperature range (-55°C to 155°C). Physical dimensions and termination configuration are identical, enabling direct PCB-level substitution without layout modifications.

Q: What are the tolerance differences between these parts?

A: The RT0805FRE07845KL specifies ±1% tolerance, while the ERA-6AEB8453V specifies ±0.1% tolerance. The ERA-6AEB8453V provides tighter tolerance control, reducing resistance value variation across the production batch.

Q: How do temperature coefficients affect part selection?

A: The RT0805FRE07845KL has a temperature coefficient of ±50ppm/°C, while the ERA-6AEB8453V has ±25ppm/°C. Lower temperature coefficient values indicate reduced resistance drift across the operating temperature range, beneficial for precision analog circuits and temperature-sensitive applications.

Q: Is the ERA-6AEB8453V suitable for automotive applications?

A: The ERA-6AEB8453V carries AEC-Q200 automotive qualification, designating it for automotive-grade use. The RT0805FRE07845KL does not specify automotive qualification.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) format with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.024", 0.60mm).

Q: Do both parts meet current compliance requirements?

A: Yes. Both the RT0805FRE07845KL and ERA-6AEB8453V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
