Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0717K8L is determined by the following critical parameters:

• Resistance Value: Must be 17.8 kOhms
• Package Type: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Power Rating: Must be 0.063W (1/16W) minimum
• Operating Temperature Range: Must support -55°C to 155°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Tolerance, temperature coefficient, and manufacturer-specific features (such as automotive qualification) are secondary parameters that define upgrade or alternative paths rather than direct equivalency. Parts with tighter tolerance (±0.1% or ±0.5%) or automotive AEC-Q200 certification represent functional upgrades while maintaining full mechanical and electrical compatibility.

Engineering Selection Recommendations

Direct Substitution (Mechanical and Electrical Compatibility)

RT0402DRE0717K8L and RT0402BRD0717K8L are direct substitutes for RT0402FRE0717K8L. Both maintain identical package dimensions, power rating, operating temperature range, and compliance certifications. Selection between these YAGEO variants depends on tolerance and temperature coefficient requirements for the application.

Automotive-Qualified Alternative

ERA-2AEB1782X (Panasonic) is a functionally equivalent substitute with automotive AEC-Q200 certification. This part is suitable for applications requiring automotive-grade reliability and qualification traceability. The ±0.1% tolerance and ±25ppm/°C temperature coefficient represent performance improvements over the standard RT0402FRE0717K8L while maintaining full mechanical compatibility.

Compliance and Certification

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. No additional qualification or testing is required for direct substitution within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0717K8L replace RT0402FRE0717K8L in production?

A: Yes. RT0402BRD0717K8L is a direct mechanical and electrical substitute. The ±0.1% tolerance is tighter than the ±1% specification of the original part, making it suitable for applications where improved accuracy is beneficial or neutral. Identical package dimensions and operating temperature range ensure PCB compatibility without design modification.

Q: What is the difference between RT0402DRE0717K8L and RT0402BRD0717K8L?

A: Both are YAGEO 17.8 kOhms thin film resistors in 0402 package. RT0402DRE0717K8L offers ±0.5% tolerance with ±50ppm/°C temperature coefficient. RT0402BRD0717K8L provides tighter ±0.1% tolerance with improved ±25ppm/°C temperature coefficient. Selection depends on circuit precision requirements.

Q: Is ERA-2AEB1782X suitable for non-automotive applications?

A: Yes. ERA-2AEB1782X meets all electrical and mechanical requirements for standard applications. The automotive AEC-Q200 certification indicates enhanced reliability and process control but does not restrict use in non-automotive designs. This part is a valid substitute for any application using the original RT0402FRE0717K8L.

Q: Are there package or footprint differences between these parts?

A: No. All substitute parts use identical 0402 (1005 Metric) package with 0.039" L × 0.020" W dimensions. Maximum seated height varies slightly: RT0402 series parts are 0.014" (0.35mm) maximum; ERA-2AEB1782X is 0.016" (0.40mm) maximum. This 0.002" difference is within standard PCB assembly tolerances and does not affect component placement or functionality.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided circuit design tolerates the tolerance and temperature coefficient variations. For applications requiring uniform performance across all resistors, specify a single part number. For applications where tolerance stack-up is not critical, substitution between these parts is permissible.
