RT0402FRE0784K5L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0784K5L is a 0402 (1005 Metric) thin film chip resistor manufactured by YAGEO with a resistance value of 84.5 kOhms and ±1% tolerance. This surface-mount device is rated for 0.063W (1/16W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while potentially offering improved tolerance specifications or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0784K5L is determined by the following criteria:

• Resistance Value: Must be 84.5 kOhms
• Package Type: Must be 0402 (1005 Metric)
• Power Rating: Must be 0.063W (1/16W) minimum
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Four substitute parts meet these criteria with variations in tolerance specification and automotive certifications. Tolerance improvements from ±1% to ±0.1% or ±0.5% represent functional upgrades. Automotive AEC-Q200 certification and anti-sulfur features are available in select alternatives for applications requiring enhanced reliability.

Parameter Comparison

Engineering Selection Recommendations

RT0402BRD0784K5L (YAGEO): Direct upgrade from the main part with improved ±0.1% tolerance and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C). Maintains YAGEO series continuity with identical package and power specifications. Suitable for applications requiring tighter tolerance control without automotive requirements.

CPF0402B84K5E1 (TE Connectivity): Offers ±0.1% tolerance with TE Connectivity manufacturing. Equivalent thermal performance and compliance profile. Appropriate for general industrial applications requiring precision resistor performance.

ERA-2AEB8452X (Panasonic): Provides ±0.1% tolerance with AEC-Q200 automotive certification. Includes automotive-grade reliability qualification. Recommended for automotive and harsh-environment applications where AEC-Q200 compliance is specified.

RG1005P-8452-D-T10 (Susumu): Combines ±0.5% tolerance with AEC-Q200 automotive certification and anti-sulfur protection. Designed for automotive applications in corrosive environments. Maintains all electrical and thermal specifications of the main part.

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

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0784K5L replace RT0402FRE0784K5L in any application?

A: Yes. RT0402BRD0784K5L is electrically and mechanically compatible. The improved ±0.1% tolerance provides tighter resistance control compared to the ±1% specification of the original part. Both parts share identical package dimensions, power ratings, and operating temperature ranges.

Q: What is the difference between the tolerance specifications?

A: The main part RT0402FRE0784K5L has ±1% tolerance, meaning the actual resistance value can vary by up to 1% from the nominal 84.5 kOhms. Substitute parts with ±0.1% tolerance (RT0402BRD0784K5L, CPF0402B84K5E1, ERA-2AEB8452X) provide tighter tolerance control, with actual values varying by only 0.1%. The RG1005P-8452-D-T10 offers ±0.5% tolerance as a middle specification.

Q: Are automotive-grade substitutes required for non-automotive applications?

A: No. ERA-2AEB8452X and RG1005P-8452-D-T10 include AEC-Q200 automotive certification, but this does not restrict their use in non-automotive applications. These parts are suitable for any application requiring the specified electrical and thermal characteristics. Automotive certification indicates additional qualification testing and reliability assurance.

Q: What does anti-sulfur protection mean in the RG1005P-8452-D-T10?

A: Anti-sulfur protection is a material treatment that prevents sulfur compounds in the environment from degrading the resistor's performance. This feature is beneficial in applications exposed to industrial atmospheres or corrosive environments. For standard indoor or controlled environments, this feature is not necessary.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All parts listed are supplied in Tape & Reel (TR) packaging with 0402 (1005 Metric) package dimensions. Physical dimensions are identical: 0.039" L x 0.020" W (1.00mm x 0.50mm). Height specifications are consistent across all parts, with ERA-2AEB8452X and RG1005P-8452-D-T10 having a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for the other parts.

Q: Can these parts be used interchangeably on existing PCBs?

A: Yes. All substitute parts are mechanically and electrically compatible with PCBs designed for the RT0402FRE0784K5L. The identical 0402 package footprint and lead configuration ensure direct substitution without PCB redesign.
