RT0402FRE073K74L Equivalent & Substitute Parts

Part Overview

The RT0402FRE073K74L is a 3.74 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 with an operating temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while tolerance, temperature coefficient, or manufacturer specifications may vary within acceptable parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE073K74L are qualified based on the following criteria:

• Identical resistance value: 3.74 kOhms
• Identical package: 0402 (1005 Metric)
• Identical power rating: 0.063W (1/16W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS and MSL compliance

Substitutes are grouped by tolerance specification, which represents the primary electrical parameter variation. Temperature coefficient and manufacturer-specific features are secondary differentiators. All substitute parts maintain mechanical and thermal compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions. Selection among substitutes depends on tolerance and temperature coefficient requirements:

RT0402BRD073K74L and RT0402BRE073K74L offer improved tolerance (±0.1%) compared to the original ±1% specification, with RT0402BRD073K74L providing tighter temperature coefficient (±25ppm/°C). RT0402DRE073K74L maintains the original ±50ppm/°C temperature coefficient while offering ±0.5% tolerance.

CPF0402B3K74E1 (TE Connectivity) and ERA-2AEB3741X (Panasonic) both provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. ERA-2AEB3741X carries AEC-Q200 automotive qualification, suitable for automotive applications. RR0510P-3741-D (Susumu) offers ±0.5% tolerance with ±25ppm/°C temperature coefficient but specifies a reduced upper operating temperature limit of 125°C.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD073K74L replace RT0402FRE073K74L directly?

A: Yes. Both parts share identical resistance (3.74 kOhms), package (0402), power rating (0.063W), and operating temperature range (-55°C ~ 155°C). RT0402BRD073K74L provides tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for applications requiring higher precision.

Q: What is the difference between RT0402BRD073K74L and RT0402BRE073K74L?

A: Both parts have ±0.1% tolerance. The primary difference is temperature coefficient: RT0402BRD073K74L specifies ±25ppm/°C while RT0402BRE073K74L specifies ±50ppm/°C. Selection depends on temperature stability requirements in the application.

Q: Is ERA-2AEB3741X suitable for automotive applications?

A: Yes. ERA-2AEB3741X carries AEC-Q200 automotive qualification and meets all electrical and mechanical specifications of the original part. It is suitable for automotive-grade applications.

Q: Why does RR0510P-3741-D have a lower maximum operating temperature?

A: RR0510P-3741-D specifies -55°C ~ 125°C operating range compared to -55°C ~ 155°C for other substitutes. This part is suitable only for applications where the upper temperature limit does not exceed 125°C.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with standard SMD assembly equipment and processes.

Q: What is the height difference between ERA-2AEB3741X and other substitutes?

A: ERA-2AEB3741X specifies maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for YAGEO RT series parts. This 0.01mm difference is within typical PCB assembly tolerances and does not affect mechanical compatibility in standard 0402 footprints.
