Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE072K05L are qualified based on the following criteria:

Primary Matching Parameters:

• Resistance value: 2.05 kOhms (exact match required)
• Package: 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: May be tighter (±0.1%) than the original ±1%
• Power rating: May be equal or higher (0.125W or 0.25W)
• Temperature coefficient: May differ within specified range
• Automotive qualification (AEC-Q200): Acceptable enhancement
• Anti-sulfur properties: Acceptable enhancement

All substitute parts maintain identical physical dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm) and MSL Level 1 rating, ensuring direct PCB compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

YAGEO RT0805BRD072K05L and RT0805BRE072K05L: These parts offer tighter tolerance (±0.1%) compared to the original RT0805FRE072K05L while maintaining identical package and power rating. Both are active production items with substantial inventory availability. RT0805BRD072K05L features improved temperature coefficient (±25ppm/°C) and is preferred for applications requiring enhanced stability. RT0805BRE072K05L maintains the original ±50ppm/°C temperature coefficient.

TE Connectivity 4-2176092-4: This part provides doubled power rating (0.25W vs. 0.125W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Selection is appropriate for applications requiring thermal margin or higher dissipation capability within the same package footprint. REACH status is vendor undefined; verify compliance requirements before selection.

Panasonic ERA-6AEB2051V: This part carries AEC-Q200 automotive qualification with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Selection is mandatory for automotive applications or systems requiring automotive-grade component reliability. Highest inventory availability (8767 units).

Susumu RG2012P-2051-B-T5: This part combines AEC-Q200 automotive qualification with anti-sulfur properties, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. Selection is appropriate for harsh environment applications or automotive systems where sulfur contamination resistance is specified. Lowest seated height (0.020" vs. 0.024") may be relevant for space-constrained designs.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring direct compatibility with existing PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD072K05L directly replace RT0805FRE072K05L without circuit modification?

A: Yes. Both parts share identical resistance value (2.05 kOhms), package dimensions (0805 / 2012 Metric), power rating (0.125W), and operating temperature range (-55°C to 155°C). The tighter tolerance (±0.1% vs. ±1%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C) of the RT0805BRD072K05L represent performance enhancements with no compatibility issues.

Q: What is the difference between RT0805BRD072K05L and RT0805BRE072K05L?

A: Both parts are YAGEO 2.05 kOhms ±0.1% resistors in 0805 package with 0.125W power rating. The primary difference is temperature coefficient: RT0805BRD072K05L specifies ±25ppm/°C while RT0805BRE072K05L specifies ±50ppm/°C. Selection depends on circuit stability requirements across the operating temperature range.

Q: When should TE Connectivity 4-2176092-4 be selected instead of YAGEO alternatives?

A: The TE Connectivity part provides 0.25W power rating compared to 0.125W in YAGEO parts. Selection is appropriate when thermal analysis indicates higher power dissipation margin is required or when component reliability under sustained power stress is a design criterion. All other electrical parameters remain compatible.

Q: Are Panasonic ERA-6AEB2051V and Susumu RG2012P-2051-B-T5 suitable for non-automotive applications?

A: Yes. Both parts exceed the electrical and environmental specifications of the original RT0805FRE072K05L and are fully compatible with non-automotive designs. AEC-Q200 qualification represents additional quality assurance and is not detrimental to general-purpose applications. Selection may be driven by inventory availability or supply chain considerations.

Q: What is the significance of anti-sulfur properties in Susumu RG2012P-2051-B-T5?

A: Anti-sulfur coating protects the component from corrosion in environments with hydrogen sulfide exposure or high-sulfur industrial atmospheres. This feature is relevant for applications in petrochemical facilities, geothermal installations, or other sulfur-rich environments. For standard indoor or controlled environments, this feature provides no functional benefit.

Q: Can a higher power-rated part (0.25W) be used in place of a 0.125W part?

A: Yes. The TE Connectivity 4-2176092-4 (0.25W) is electrically and mechanically compatible with designs specified for 0.125W parts. Higher power rating provides thermal margin and does not introduce compatibility issues. PCB copper trace sizing and thermal management design remain unchanged.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original RT0805FRE072K05L is also ROHS3 compliant. All parts are suitable for applications with RoHS compliance requirements.
