Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN73C2A4K7BTDF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.7 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: Equal to or tighter than ±0.1%
• Power rating: Equal to or greater than 0.1W
• Temperature coefficient: Equal to or lower absolute value
• Manufacturer and series designation

All identified substitute parts meet the mandatory matching parameters. Variations in tolerance, power rating, and temperature coefficient represent either equivalent or upgraded specifications suitable for direct substitution in applications designed for the RN73C2A4K7BTDF.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARB472V be used as a direct replacement for RN73C2A4K7BTDF?

A: Yes. Both parts share identical resistance (4.7 kOhms), tolerance (±0.1%), package (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The ERA-6ARB472V has a higher power rating (0.125W versus 0.1W) and lower maximum height (0.024" versus 0.026"), making it a compatible substitute.

Q: What is the advantage of RG2012L-472-L-T05 over the original RN73C2A4K7BTDF?

A: The RG2012L-472-L-T05 provides superior tolerance (±0.01% versus ±0.1%) and significantly lower temperature coefficient (±2ppm/°C versus ±10ppm/°C). These specifications result in improved long-term stability and reduced drift across temperature variations. The part also includes Anti-Sulfur and AEC-Q200 automotive features.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the original RN73C2A4K7BTDF.

Q: Does the increased power rating of ERA-6ARW472V affect circuit performance?

A: No. Power rating represents the maximum power the component can safely dissipate. A higher power rating does not alter electrical performance in the circuit. The component will dissipate only the power required by the circuit design.

Q: What is the significance of AEC-Q200 qualification on substitute parts?

A: AEC-Q200 is an automotive qualification standard indicating the part meets reliability and performance requirements for automotive applications. Parts carrying this qualification (ERA-6ARB472V, ERA-6ARW472V, and RG2012L-472-L-T05) are suitable for automotive and high-reliability applications.

Q: Can RG2012L-472-L-T05 be used in applications where temperature stability is critical?

A: Yes. The RG2012L-472-L-T05 has a temperature coefficient of ±2ppm/°C, which is significantly lower than the original part's ±10ppm/°C. This lower coefficient results in reduced resistance drift across the operating temperature range, making it suitable for precision measurement and temperature-sensitive applications.

Q: Are there any height restrictions when substituting these parts?

A: The substitute parts have maximum seated heights ranging from 0.020" to 0.024", compared to the original part's 0.026". All substitute parts are lower in profile, which is beneficial for space-constrained PCB designs. Verify that your PCB assembly process and component placement equipment accommodate these dimensions.

Q: What is the MSL rating for all parts in this comparison?

A: All parts, including the original RN73C2A4K7BTDF and all substitutes, carry MSL 1 (Unlimited) rating. This indicates unlimited shelf life and no moisture sensitivity concerns during storage and handling.
