Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJ0805FRE073R9L is determined by the following mandatory parameters:

• Resistance value: 3.9 Ohms (exact match required)
• Package type: 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Temperature coefficient: ±50ppm/°C
• Moisture sensitivity: MSL 1 or better

Tolerance and power rating may be upgraded to higher specifications without functional degradation. Operating temperature range may be extended. All substitute parts must maintain compatibility with the 0805 package footprint and land pattern.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRE073R9L and RT0805FRE073R9L are direct YAGEO upgrades with active product status. Both maintain the same 0805 package footprint and thin film composition. RT0805DRE073R9L offers improved tolerance (±0.5%) and increased power rating (0.125W) with extended operating temperature to 155°C. RT0805FRE073R9L matches the original ±1% tolerance while providing the same power and temperature upgrades. Both are ROHS3 compliant.

RNCF0805DTC3R90 from Stackpole Electronics Inc is a manufacturer-recommended alternative with AEC-Q200 automotive qualification. This part provides the highest power rating (0.25W) and ±0.5% tolerance with identical package and thermal specifications. Selection of this part is appropriate for applications requiring automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE073R9L replace RJ0805FRE073R9L directly? A: Yes. Both parts share identical resistance (3.9 Ohms), package (0805), composition (thin film), and temperature coefficient (±50ppm/°C). RT0805DRE073R9L provides superior tolerance (±0.5% vs ±1%) and higher power rating (0.125W vs 0.1W) with extended operating temperature range.

Q: What is the difference between RT0805DRE073R9L and RT0805FRE073R9L? A: Both are YAGEO active products in 0805 package with identical resistance and temperature specifications. The primary difference is tolerance: RT0805DRE073R9L offers ±0.5% while RT0805FRE073R9L maintains ±1%. Both provide 0.125W power rating and -55°C to 155°C operating range.

Q: Is RNCF0805DTC3R90 suitable for non-automotive applications? A: Yes. RNCF0805DTC3R90 meets all functional requirements for the original RJ0805FRE073R9L. The AEC-Q200 automotive qualification indicates enhanced reliability and quality assurance. The 0.25W power rating and ±0.5% tolerance provide performance margin for general applications.

Q: Are all substitute parts MSL 1 rated? A: Yes. All substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's moisture handling capability.

Q: Will substitute parts fit the same PCB footprint? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical compatibility with existing PCB layouts is maintained.
