• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package form factor: 0805 (2012 Metric)
• Composition: Thick Film
• Application feature: Current Sense
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Environmental compliance: RoHS3 Compliant, REACH Unaffected

The RLP73K2AR62FTDF manufactured by TE Connectivity Passive Product meets all specified parameters and qualifies as a direct substitute within the same electrical and mechanical classification.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR0805FTR620 and RLP73K2AR62FTDF maintain Active product status and carry identical environmental compliance certifications (RoHS3 Compliant, REACH Unaffected). Selection between these parts may be based on supply chain availability, lead time requirements, or procurement preferences, as electrical and mechanical specifications are fully equivalent. The RLP73K2AR62FTDF is available in higher inventory quantity (4654 Pcs) compared to the CSR0805FTR620 (1126 Pcs), which may influence sourcing decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the RLP73K2AR62FTDF replace the CSR0805FTR620 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package dimensions, and operating specifications. Direct substitution is supported without circuit redesign.

Q: Are there any differences in environmental compliance between these parts?

A: No. Both parts carry RoHS3 Compliant status, REACH Unaffected designation, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution eligibility for this resistor category?

A: Substitution requires exact matching of resistance value (620 mOhms), tolerance (±1%), power rating (0.25W), package form factor (0805), composition (Thick Film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and physical dimensions (0.079" L x 0.049" W).

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.026" (0.65mm), ensuring PCB layout compatibility.

Q: What is the significance of the Current Sense feature?

A: Current Sense designation indicates these resistors are optimized for precision current measurement applications where low resistance values and tight tolerance are critical for accurate signal conditioning.
