Substitute Part Grouping Explanation

Substitution of the RT0805FRE0784R5L is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value: 84.5 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

Secondary Substitution Parameters (Allowable Variations):

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Power Rating: 0.125W or higher (0.25W acceptable as upgrade)
• Temperature Coefficient: ±50ppm/°C or better (±25ppm/°C acceptable as upgrade)
• Manufacturer: Different manufacturers acceptable if all primary parameters match

The identified substitute parts maintain identical resistance, package, and composition specifications while offering improved tolerance, power handling, or automotive certification.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0784R5L (YAGEO): Direct upgrade from the main part with improved tolerance specification (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C). Maintains identical power rating and package specifications. Suitable for applications requiring tighter tolerance control without changing board layout or thermal design.

1-2176091-7 (TE Connectivity): Provides higher power dissipation capability (0.25W versus 0.125W) while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient. Identical package footprint and mechanical dimensions. Appropriate for applications with increased thermal stress or power budget requirements.

ERA-6AEB84R5V (Panasonic): Offers AEC-Q200 automotive qualification with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains 0.125W power rating and 0805 package specifications. Required for automotive applications or systems demanding automotive-grade component reliability.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0784R5L replace RT0805FRE0784R5L in any application?

A: Yes. RT0805BRD0784R5L is a direct upgrade with improved tolerance (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). The identical 0805 package, 84.5 Ohm resistance, and 0.125W power rating ensure pin-for-pin compatibility and identical board layout requirements.

Q: When should 1-2176091-7 be selected instead of the main part?

A: Select 1-2176091-7 when the application requires higher power dissipation (0.25W versus 0.125W). The higher power rating provides thermal margin in high-current or high-ambient-temperature environments. The 0805 package footprint remains identical, requiring no PCB redesign.

Q: Is ERA-6AEB84R5V suitable for non-automotive applications?

A: Yes. ERA-6AEB84R5V meets all specifications of the main part and exceeds them with AEC-Q200 automotive qualification, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. It is a valid substitute for any application, with the added benefit of automotive-grade reliability.

Q: Do all substitute parts use the same 0805 package 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). No PCB layout modifications are required for substitution.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance specifies the maximum deviation from the nominal 84.5 Ohm value. ±1% allows deviation up to ±0.845 Ohms, while ±0.1% limits deviation to ±0.0845 Ohms. Tighter tolerance (±0.1%) is required for precision analog circuits, measurement equipment, and applications with strict impedance matching requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT0805BRD0784R5L, 1-2176091-7, and ERA-6AEB84R5V are all ROHS3 compliant with MSL 1 rating, meeting standard environmental and storage requirements.
