RT0402FRE072K15L Equivalent & Substitute Parts

Part Overview

The RT0402FRE072K15L is a 2.15 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 is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package dimensions, and electrical ratings are required due to inventory constraints or design optimization needs.

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE072K15L are qualified based on the following criteria:

Identical resistance value: 2.15 kOhms
Identical package / case: 0402 (1005 Metric)
Identical power rating: 0.063W (1/16W)
Identical composition: Thin Film
Identical operating temperature range: -55°C ~ 155°C
Identical RoHS compliance: ROHS3 Compliant
Identical MSL rating: 1 (Unlimited)

Substitute parts may differ in tolerance specification (±0.1% vs ±1%) and temperature coefficient, provided all other electrical and mechanical parameters remain equivalent. All identified substitutes maintain the same footprint and thermal characteristics required for direct board-level replacement.

Engineering Selection Recommendations

All three substitute parts maintain active production status and ROHS3 compliance equivalent to the main part RT0402FRE072K15L. Selection between substitutes is determined by application-specific requirements:

RT0402BRD072K15L (YAGEO) provides tolerance upgrade to ±0.1% with reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package footprint and height specifications.

CPF0402B2K15E1 (TE Connectivity Passive Product, Neohm series) offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with identical dimensional specifications.

ERA-2AEB2151X (Panasonic Electronic Components, ERA-2A series) provides ±0.1% tolerance, ±25ppm/°C temperature coefficient, and automotive AEC-Q200 qualification. Maximum seated height is 0.016" (0.40mm), which is 0.002" greater than the main part and substitute alternatives.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD072K15L replace RT0402FRE072K15L in all applications?

A: Yes. Both parts share identical resistance value (2.15 kOhms), package (0402), power rating (0.063W), composition (thin film), and operating temperature range (-55°C ~ 155°C). The substitute offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for direct substitution.

Q: What is the difference between CPF0402B2K15E1 and RT0402BRD072K15L?

A: Both parts are electrically equivalent with 2.15 kOhms ±0.1% resistance, 0.063W power rating, and ±25ppm/°C temperature coefficient. The primary difference is manufacturer: CPF0402B2K15E1 is manufactured by TE Connectivity (Neohm series), while RT0402BRD072K15L is manufactured by YAGEO (RT series). Footprint and package specifications are identical.

Q: Is ERA-2AEB2151X suitable for standard consumer applications?

A: ERA-2AEB2151X is qualified to automotive AEC-Q200 standard and is suitable for both automotive and consumer applications. The maximum seated height of 0.016" (0.40mm) is 0.002" taller than other substitutes. Verify PCB clearance specifications before selection if height-constrained designs are present.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT0402BRD072K15L, CPF0402B2K15E1, and ERA-2AEB2151X are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the main part RT0402FRE072K15L.

Q: What is the significance of temperature coefficient differences?

A: The main part RT0402FRE072K15L has ±50ppm/°C temperature coefficient, while all substitutes have ±25ppm/°C. Lower temperature coefficient indicates reduced resistance variation across the operating temperature range (-55°C ~ 155°C). Applications requiring stable resistance values across temperature extremes benefit from substitute parts with ±25ppm/°C specification.
