CSR1206FKR470 Equivalent & Substitute Parts

Part Overview

The CSR1206FKR470 is a 470 mOhms ±1% 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This current sense resistor is designed for precision measurement applications requiring stable resistance values across operating temperatures from -55°C to 155°C. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for this resistor category.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FKR470 is determined by strict equivalence across the following parameters:

• Resistance value: 470 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Current sense application capability
• RoHS3 compliance
• MSL rating: 1 or better

Two substitute parts meet these criteria: the CRM1206-FX-R470ELF from Bourns Inc. and the RCWE1206R470FKEA from Vishay Dale. Both maintain identical electrical specifications and package compatibility while offering alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with full ROHS3 compliance and identical core electrical specifications. Selection between these options depends on application-specific requirements:

The CSR1206FKR470 from Stackpole Electronics Inc. serves as the primary reference part with 687 units in current inventory.

The CRM1206-FX-R470ELF from Bourns Inc. provides direct electrical and mechanical equivalence with higher inventory availability (12,678 units), making it suitable for high-volume applications requiring consistent supply.

The RCWE1206R470FKEA from Vishay Dale includes AEC-Q200 automotive qualification and moisture-resistant construction, qualifying it for automotive and harsh environment applications. This part carries the highest inventory level (18,243 units) and is recommended when automotive-grade reliability or enhanced moisture resistance is specified.

Frequently Asked Questions (FAQ)

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. All three parts share identical resistance (470 mOhms), tolerance (±1%), power rating (0.5W), package (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). They are electrically and mechanically interchangeable for standard current sense applications.

Q: What is the difference between the Stackpole, Bourns, and Vishay Dale versions?

A: The electrical specifications are identical. The Vishay Dale RCWE1206R470FKEA includes AEC-Q200 automotive qualification and moisture-resistant construction, making it suitable for automotive and demanding environmental conditions. The Stackpole and Bourns versions are functionally equivalent for general industrial applications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1206 package specification. Stackpole specifies 0.120" L x 0.061" W (3.05mm x 1.55mm) with 0.026" max height. Bourns and Vishay Dale specify 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" and 0.028" max heights respectively. These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which part should I select for new designs?

A: For standard applications, any of the three parts is acceptable. For automotive applications or environments requiring enhanced moisture resistance, specify the RCWE1206R470FKEA. For maximum supply availability, the Vishay Dale part offers the highest inventory level.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and are REACH unaffected, meeting current environmental and regulatory requirements.
