Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJ0805FRE073R3L is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.3 Ohms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±50ppm/°C
• Number of Terminations: 2
• Moisture Sensitivity Level: MSL 1 or better

Allowable Variations:

• Tolerance: May be equal or tighter (±1% or ±0.5%)
• Power Rating: May be equal or higher (0.1W or greater)
• Operating Temperature Range: May be equal or extended
• Product Status: Active preferred over obsolete

Two substitute parts meet these criteria and are identified below.

Parameter Comparison

Engineering Selection Recommendations

RT0805FRE073R3L (YAGEO Upgrade): This part provides direct substitution with improved specifications. It maintains identical resistance, tolerance, and temperature coefficient while offering higher power rating (0.125W vs 0.1W) and extended operating temperature range (-55°C to 155°C vs -55°C to 125°C). Active product status ensures long-term availability. ROHS3 compliance supports regulatory requirements.

RNCF0805DTC3R30 (Stackpole MFR Recommended): This part offers enhanced performance with tighter tolerance (±0.5% vs ±1%) and significantly higher power rating (0.25W vs 0.1W). Extended operating temperature range and AEC-Q200 automotive qualification provide additional design margin. ROHS3 compliance and active status support procurement continuity.

Selection between these substitutes depends on application requirements for power dissipation margin, tolerance precision, and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can RT0805FRE073R3L directly replace RJ0805FRE073R3L?

A: Yes. Both parts share identical resistance (3.3 Ohms), tolerance (±1%), package (0805), composition (thin film), and temperature coefficient (±50ppm/°C). The RT series offers higher power rating and extended temperature range, making it a direct upgrade with no circuit modifications required.

Q: What is the difference between the two substitute parts?

A: RT0805FRE073R3L is a YAGEO product with 0.125W power rating and standard thin film construction. RNCF0805DTC3R30 is a Stackpole product with 0.25W power rating, tighter ±0.5% tolerance, and AEC-Q200 automotive qualification. Both are electrically compatible; selection depends on power dissipation requirements and automotive application needs.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations are minimal (0.024" to 0.026"), presenting no PCB layout concerns.

Q: Can I use RNCF0805DTC3R30 in place of RJ0805FRE073R3L?

A: Yes. The RNCF part meets all mandatory substitution parameters with enhanced specifications. The tighter tolerance (±0.5%) and higher power rating (0.25W) provide improved performance margin. AEC-Q200 qualification is beneficial for automotive applications but does not restrict use in non-automotive designs.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements. All three parts carry this rating, ensuring consistent handling and storage procedures across substitutions.
