RT0402FRE075K49L Equivalent & Substitute Parts

Part Overview

The RT0402FRE075K49L is a 5.49 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 ROHS3 compliant with MSL 1 rating and maintains active product status. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while offering improved tolerance, temperature coefficient performance, or enhanced reliability features.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three critical parameters: resistance value (5.49 kOhms), package type (0402 / 1005 Metric), and power rating (0.063W / 1/16W). All identified substitutes maintain these core specifications. Secondary parameters including tolerance, temperature coefficient, and operating temperature range define performance tier classifications. Substitutes are grouped by tolerance grade (±0.1%, ±0.5%) and feature set (standard thin film, automotive-grade with anti-sulfur properties).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. RT0402BRD075K49L and CPF0402B5K49E1 offer improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C), suitable for precision analog circuits. RG1005P-5491-B-T5 includes automotive AEC-Q200 qualification and anti-sulfur properties, appropriate for automotive and harsh environment applications. RR0510P-5491-D operates to 125°C maximum, limiting use to applications not exceeding this temperature threshold. Selection depends on application tolerance requirements, environmental conditions, and temperature operating range constraints.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD075K49L directly replace RT0402FRE075K49L? A: Yes. Both parts share identical resistance (5.49 kOhms), power rating (0.063W), and 0402 package. RT0402BRD075K49L provides tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Q: What is the difference between CPF0402B5K49E1 and RT0402BRD075K49L? A: Both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. CPF0402B5K49E1 is manufactured by TE Connectivity Passive Product (Neohm series), while RT0402BRD075K49L is YAGEO. Electrical performance is equivalent; selection depends on supply chain and manufacturer preference.

Q: When should RG1005P-5491-B-T5 be selected? A: RG1005P-5491-B-T5 includes AEC-Q200 automotive qualification and anti-sulfur coating. Select this part for automotive applications, high-reliability systems, or environments with sulfur exposure risk.

Q: Is RR0510P-5491-D suitable for all applications? A: RR0510P-5491-D operates to 125°C maximum, compared to 155°C for other substitutes. Use only in applications where maximum operating temperature does not exceed 125°C.

Q: Are all substitutes available in Tape & Reel packaging? A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging, maintaining manufacturing compatibility with automated assembly processes.

Q: What tolerance should be selected for precision applications? A: For precision analog circuits, select ±0.1% tolerance parts: RT0402BRD075K49L, CPF0402B5K49E1, or RG1005P-5491-B-T5. The original RT0402FRE075K49L with ±1% tolerance is suitable for general-purpose applications with relaxed tolerance requirements.
