Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE073K4L is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 3.4 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Composition: Thin Film (exact match required)

Secondary Compatibility Parameters:

• Tolerance: ±1% or better (tighter tolerance acceptable)
• Power rating: 0.125W minimum (higher power rating acceptable)
• Temperature coefficient: ±50ppm/°C or better (lower coefficient acceptable)
• RoHS compliance: ROHS3 Compliant (required)
• Moisture sensitivity: MSL 1 (required)

All identified substitute parts meet or exceed these criteria, ensuring functional and physical compatibility in the original circuit application.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD073K4L (YAGEO): Direct upgrade within the same manufacturer series. Offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. ROHS3 compliant and actively produced.

6-2176092-3 (TE Connectivity): Cross-manufacturer substitute with higher power rating (0.25W vs 0.125W), providing additional thermal margin. Tolerance and temperature coefficient match RT0805BRD073K4L. ROHS3 compliant and actively produced.

ERA-6AEB3401V (Panasonic): Automotive-grade substitute with AEC-Q200 certification. Tolerance and temperature coefficient equivalent to RT0805BRD073K4L. Suitable for applications requiring automotive qualification. ROHS3 compliant and actively produced.

RG2012P-3401-B-T5 (Susumi): Automotive-grade substitute with AEC-Q200 certification and anti-sulfur feature. Tolerance and temperature coefficient equivalent to other upgrades. Lowest seated height (0.020" vs 0.024"). ROHS3 compliant and actively produced.

All substitute parts are actively produced, ROHS3 compliant, and maintain MSL 1 rating. Selection should be based on application requirements for automotive qualification, power dissipation margin, and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD073K4L replace RT0805FRE073K4L in any application? A: Yes. RT0805BRD073K4L meets all primary matching parameters (3.4 kOhms, 0805 package, thin film composition, -55°C to 155°C operating range) and exceeds secondary parameters with tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C).

Q: What is the difference between the ±1% and ±0.1% tolerance versions? A: Tolerance specifies the maximum deviation from the nominal 3.4 kOhms value. ±1% allows ±34 ohms deviation; ±0.1% allows ±3.4 ohms deviation. Tighter tolerance (±0.1%) is suitable for precision circuits where resistance accuracy is critical.

Q: Why does 6-2176092-3 have a higher power rating (0.25W vs 0.125W)? A: Higher power rating indicates greater thermal dissipation capability. This provides additional safety margin in applications with higher current or power dissipation requirements, though the component remains physically compatible in 0805 package footprints.

Q: Are ERA-6AEB3401V and RG2012P-3401-B-T5 suitable for non-automotive applications? A: Yes. Automotive-grade components (AEC-Q200 certified) exceed standard industrial specifications and are fully compatible with non-automotive circuits. They offer enhanced reliability and environmental performance.

Q: What does anti-sulfur feature in RG2012P-3401-B-T5 mean? A: Anti-sulfur coating protects the component from sulfur-containing environmental contaminants, extending operational life in harsh industrial or marine environments. This feature is beneficial but not required for standard applications.

Q: Are all substitute parts available in Tape & Reel (TR) packaging? A: Yes. All identified substitute parts are supplied in Tape & Reel packaging, maintaining compatibility with automated assembly processes.

Q: Can I mix different substitute parts in the same circuit board design? A: Yes. All substitute parts are functionally and physically equivalent for the 0805 package footprint. Mixed usage is acceptable from an engineering standpoint, though procurement and inventory management may favor standardization on a single part number.
