Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0603FRE0754K9L is determined by the following critical parameters: resistance value (54.9 kOhms), package type (0603), power rating (0.1W minimum), and operating temperature range (-55°C ~ 155°C). All substitute parts maintain identical resistance, package, and temperature specifications. Substitutes are grouped by tolerance grade and manufacturer:

• Tolerance Grade Upgrades (±0.1%): RT0603BRD0754K9L (YAGEO), 6-2176089-6 (TE Connectivity), ERA-3AEB5492V (Panasonic)
• Tolerance Grade Intermediate (±0.5%): RT0603DRD0754K9L, RT0603DRE0754K9L (YAGEO)
• Specialized Application: ERA-3AEB5492V includes AEC-Q200 automotive qualification

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions. Selection between substitutes depends on application requirements:

• RT0603BRD0754K9L: Direct YAGEO upgrade offering ±0.1% tolerance and ±25ppm/°C temperature coefficient with highest inventory availability (14,649 pcs).
• RT0603DRD0754K9L and RT0603DRE0754K9L: Intermediate tolerance options (±0.5%) for cost-sensitive applications where ±1% tolerance is acceptable.
• 6-2176089-6: TE Connectivity alternative with higher power rating (0.167W) for applications requiring additional thermal margin.
• ERA-3AEB5492V: Panasonic AEC-Q200 qualified option for automotive and high-reliability applications requiring automotive-grade certification.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0754K9L replace RT0603FRE0754K9L directly? A: Yes. Both parts share identical resistance (54.9 kOhms), package (0603), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). RT0603BRD0754K9L offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0603DRD0754K9L and RT0603DRE0754K9L? A: Both parts have identical resistance, tolerance (±0.5%), and power rating. The primary difference is temperature coefficient: RT0603DRD0754K9L has ±25ppm/°C while RT0603DRE0754K9L has ±50ppm/°C. Selection depends on thermal stability requirements.

Q: Is 6-2176089-6 compatible with the original part? A: Yes, with consideration for power rating. The TE Connectivity part has a higher power rating (0.167W vs 0.1W) and ±0.1% tolerance. It is electrically and mechanically compatible in 0603 package applications.

Q: Can ERA-3AEB5492V be used in non-automotive applications? A: Yes. ERA-3AEB5492V meets all electrical and mechanical specifications of the original part and exceeds them with AEC-Q200 automotive qualification. It is suitable for any application requiring 54.9 kOhms ±0.1% in 0603 package.

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 automated assembly processes.
