RT0402FRE071K43L Equivalent & Substitute Parts

Part Overview

The RT0402FRE071K43L is a 1.43 kOhms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design upgrades for improved tolerance, or application-specific certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE071K43L is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 1.43 kOhms
• Package / Case: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Packaging type: Tape & Reel (TR)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Tolerance: May be equal or tighter (±1% or better)
• Temperature coefficient: May be equal or lower
• Manufacturer: Different manufacturers permitted
• Series designation: Different series permitted
• Height seated (max): Variations within 0.001" to 0.002" acceptable for 0402 package class
• Certifications: Additional certifications (AEC-Q200, Anti-Sulfur) permitted

All four substitute parts meet these criteria with identical resistance, package, power rating, and composition specifications. Three substitutes offer improved tolerance (±0.1% versus ±1%), and two include automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original RT0402FRE071K43L.

RT0402BRD071K43L (YAGEO): Direct manufacturer upgrade offering improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package dimensions and height specifications. Highest inventory availability (16,788 pcs).

CPF0402B1K43E1 (TE Connectivity Passive Product): Equivalent tolerance and temperature coefficient performance to RT0402BRD071K43L with established supply chain through TE Connectivity. Suitable for applications requiring multi-source qualification.

ERA-2AEB1431X (Panasonic Electronic Components): Includes AEC-Q200 automotive qualification with identical electrical specifications. Height seated maximum increases to 0.016" (0.40mm). Appropriate for automotive and harsh environment applications.

RG1005P-1431-B-T5 (Susumu): Combines AEC-Q200 automotive qualification with Anti-Sulfur feature protection. Height seated maximum increases to 0.016" (0.40mm). Suitable for automotive applications in corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD071K43L replace RT0402FRE071K43L in any application?

A: Yes. Both parts share identical resistance (1.43 kOhms), package (0402), power rating (0.063W), composition (thin film), operating temperature range (-55°C to 155°C), and physical dimensions. RT0402BRD071K43L offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it functionally superior for precision applications.

Q: What is the difference between the standard and automotive-qualified substitutes?

A: ERA-2AEB1431X and RG1005P-1431-B-T5 include AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental testing standards. RG1005P-1431-B-T5 additionally features Anti-Sulfur protection. These certifications are required for automotive applications but are not necessary for general industrial or consumer electronics.

Q: Are there height differences between substitute parts?

A: RT0402FRE071K43L and RT0402BRD071K43L both specify 0.014" (0.35mm) maximum seated height. ERA-2AEB1431X and RG1005P-1431-B-T5 specify 0.016" (0.40mm) maximum seated height. This 0.002" difference is within standard 0402 package tolerance and does not affect PCB assembly compatibility for standard reflow processes.

Q: Which substitute offers the best tolerance performance?

A: RT0402BRD071K43L, CPF0402B1K43E1, ERA-2AEB1431X, and RG1005P-1431-B-T5 all offer ±0.1% tolerance, which is 10 times tighter than the original RT0402FRE071K43L (±1%). Selection between these four depends on manufacturer preference, supply chain requirements, and application-specific certifications.

Q: Can I use ERA-2AEB1431X or RG1005P-1431-B-T5 in non-automotive applications?

A: Yes. Automotive-qualified parts exceed the performance and reliability requirements of general industrial and consumer applications. Their use in non-automotive circuits provides additional margin and reliability assurance.

Q: What is the Tape & Reel (TR) packaging specification?

A: Tape & Reel packaging is the standard format for automated PCB assembly. All listed parts use this packaging, ensuring compatibility with standard pick-and-place equipment and reflow soldering processes.
