RT0805FRE07154KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07154KL is a 154 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by YAGEO, this component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently active in production with 670 pieces in stock.

Substitute parts are identified when they maintain identical resistance value, package form factor, power rating, and operating temperature range while offering improved tolerance, temperature coefficient, or automotive qualification. Substitution becomes necessary when enhanced precision, reliability certifications, or specific environmental performance is required for application requirements.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07154KL (YAGEO): Direct upgrade from RT0805FRE07154KL with improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). Maintains YAGEO series continuity and ROHS3 compliance. Suitable for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-6AEB1543V (Panasonic): Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with automotive AEC-Q200 qualification. Recommended for automotive and high-reliability applications where component traceability and qualification documentation are mandatory. Higher inventory availability (15583 units).

ERA-6AED1543V (Panasonic): Automotive AEC-Q200 qualified with ±0.5% tolerance and ±25ppm/°C temperature coefficient. Suitable for automotive applications where tolerance requirements are less stringent than ±0.1%. Highest inventory availability (30323 units) among all substitutes.

RG2012P-1543-B-T5 (Susumu): Combines ±0.1% tolerance, ±25ppm/°C temperature coefficient, and automotive AEC-Q200 qualification with anti-sulfur feature. Recommended for harsh automotive environments or applications requiring sulfur resistance. Lowest maximum seated height (0.020" vs 0.024") may be relevant for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07154KL be used as a direct replacement for RT0805FRE07154KL?

A: Yes. Both parts share identical resistance, power rating, package, and operating temperature range. RT0805BRD07154KL provides improved tolerance and temperature coefficient specifications, making it a direct upgrade with no design modifications required.

Q: What is the difference between YAGEO and Panasonic substitutes?

A: YAGEO substitutes (RT0805BRD07154KL) maintain the same series without automotive qualification. Panasonic substitutes (ERA-6AEB1543V, ERA-6AED1543V) include automotive AEC-Q200 certification, required for automotive applications. Panasonic parts also use Cut Tape & Digi-Reel packaging versus Tape & Reel.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status identical to the main part.

Q: Does the anti-sulfur feature of RG2012P-1543-B-T5 affect electrical performance?

A: No. Anti-sulfur treatment is a material property that enhances reliability in sulfur-containing environments without altering electrical characteristics. Resistance, tolerance, and temperature coefficient remain unchanged.

Q: Can parts with different tolerances be mixed in the same circuit?

A: Tolerance selection depends on circuit requirements. Parts with ±0.1% tolerance (RT0805BRD07154KL, ERA-6AEB1543V, RG2012P-1543-B-T5) are suitable for precision applications. ERA-6AED1543V with ±0.5% tolerance is acceptable for general-purpose applications where the original ±1% specification is adequate.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance change over operating temperature range. Lower values (±25ppm/°C) provide better stability across temperature extremes. For -55°C to 155°C operation, ±25ppm/°C results in approximately ±0.325% maximum drift versus ±0.5% for ±50ppm/°C.

Q: Are there packaging compatibility concerns when substituting?

A: All substitute parts use identical 0805 (2012 Metric) package with 2.00mm x 1.25mm footprint. Seated height varies slightly (0.020" to 0.024" maximum), which is negligible for standard PCB assembly. Packaging format (Tape & Reel vs Cut Tape) affects supply chain handling but not component compatibility.
