Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-1622821-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 470 mOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Features: Current Sense capability
• Number of Terminations: 2
• Moisture Sensitivity Level: MSL 1

Allowable Variations:

• Operating temperature range may extend beyond the original specification
• Temperature coefficient may improve (lower value)
• Product status may transition from obsolete to active
• Compliance certifications and RoHS status may be enhanced
• Physical dimensions may have minor variations within package tolerance

The substitute parts listed below satisfy all mandatory matching parameters and are therefore electrically and mechanically interchangeable with the original component.

Parameter Comparison

Engineering Selection Recommendations

Stackpole Electronics CSR0805FKR470: This component provides direct electrical equivalence to the TE Connectivity 3-1622821-3 with identical resistance, tolerance, power rating, and temperature coefficient specifications. The part maintains active product status and extends the operating temperature range to -55°C ~ 155°C. RoHS3 compliance is confirmed. This substitute is suitable for applications requiring standard current sense functionality without automotive qualification requirements.

Vishay Dale RCWE0805R470FKEA: This component exceeds the electrical requirements of the original part through improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and extended operating temperature range (-55°C ~ 155°C). The part carries AEC-Q200 automotive qualification and moisture-resistant thick film construction, providing enhanced reliability for demanding applications. RoHS3 compliance is confirmed. This substitute is designated as an upgrade option for applications requiring automotive-grade components or enhanced environmental performance.

Both substitute parts are active products with confirmed availability and are electrically and mechanically interchangeable with the obsolete TE Connectivity component across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the Stackpole CSR0805FKR470 be used as a direct replacement for the TE Connectivity 3-1622821-3?

A: Yes. Both components share identical resistance (470 mOhms), tolerance (±1%), power rating (0.25W), package (0805), composition (thick film), and current sense features. The Stackpole part is electrically and mechanically interchangeable.

Q: What is the difference between the Stackpole and Vishay Dale substitutes?

A: The Vishay Dale RCWE0805R470FKEA provides improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), extended operating temperature range to 155°C, and AEC-Q200 automotive qualification. The Stackpole CSR0805FKR470 maintains the original temperature coefficient specification and standard industrial qualification.

Q: Are there physical dimension differences between these parts?

A: The TE Connectivity and Stackpole parts share identical length and width (0.079" x 0.049"). The Vishay Dale part has a slightly wider dimension (0.051" W versus 0.049" W), remaining within 0805 package tolerance. The TE Connectivity part has a lower seated height (0.020" versus 0.026"), but all three parts fit the 0805 package footprint.

Q: Do all substitute parts meet RoHS requirements?

A: The Stackpole CSR0805FKR470 and Vishay Dale RCWE0805R470FKEA are both ROHS3 compliant. The original TE Connectivity part does not specify RoHS status.

Q: Which substitute should be selected for automotive applications?

A: The Vishay Dale RCWE0805R470FKEA carries AEC-Q200 automotive qualification and is the appropriate selection for automotive applications. The Stackpole part is suitable for industrial and consumer applications.

Q: Are these parts available in different packaging formats?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging. The original TE Connectivity part packaging format is not specified in the available data.

Q: What is the moisture sensitivity level for all three parts?

A: All three components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
