CSR2010FTR200 Equivalent & Substitute Parts

Part Overview

The CSR2010FTR200 is a 200 mOhms ±1% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This current sense thick film resistor operates across -55°C to 155°C and is designed for applications requiring precision low-resistance measurements. The part is active and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this product category.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FTR200 is determined by the following criteria:

Resistance value: 200 mOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 1W (exact match required)
Package: 2010 (5025 Metric) (exact match required)
Composition: Thick Film (exact match required)
Features: Current Sense capability (required)
Operating temperature range: -55°C ~ 155°C (minimum requirement)
RoHS compliance: ROHS3 Compliant (required)
Moisture sensitivity: MSL 1 (required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in temperature coefficient and physical dimensions within supplier tolerances do not affect functional substitutability.

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between the CSR2010FTR200 and its substitutes depends on application-specific requirements:

CSRN2010FKR200 (Stackpole Electronics Inc) provides direct manufacturer continuity within the Stackpole product line. Temperature coefficient specification is ±250ppm/°C, which is wider than the primary part. Physical dimensions remain within 2010 package tolerance.

CRM2010-FX-R200ELF (Bourns Inc.) offers equivalent electrical performance with ±100ppm/°C temperature coefficient matching the primary part. Dimensional specifications align with standard 2010 package tolerances.

RCWE2010R200FKEA (Vishay Dale) includes automotive AEC-Q200 qualification and moisture-resistant features. Temperature coefficient is ±100ppm/°C. This part is designated as manufacturer recommended and is suitable for applications requiring automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FKR200 be used as a direct replacement for CSR2010FTR200?

A: Yes. Both parts share identical resistance (200 mOhms), tolerance (±1%), power rating (1W), package (2010), and composition (thick film). The temperature coefficient difference (±250ppm/°C vs ±100ppm/°C) does not affect substitutability for standard current sense applications. Physical dimensions remain within 2010 package specifications.

Q: What is the difference between CRM2010-FX-R200ELF and the primary part?

A: Electrical specifications are equivalent: 200 mOhms ±1% 1W with ±100ppm/°C temperature coefficient. The manufacturer is Bourns Inc. instead of Stackpole Electronics Inc. Package and composition are identical. Physical dimensions vary slightly within 2010 package tolerance.

Q: Is RCWE2010R200FKEA suitable for automotive applications?

A: Yes. RCWE2010R200FKEA carries AEC-Q200 automotive qualification and includes moisture-resistant features. Electrical specifications match the primary part (200 mOhms ±1% 1W). This part is designated as manufacturer recommended.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All parts are supplied in Tape & Reel (TR) packaging, matching the primary part's packaging specification.

Q: Do physical dimension variations affect PCB layout compatibility?

A: Physical dimensions vary within 2010 (5025 Metric) package tolerance specifications. Length is consistent at 0.197" (5.00mm) across all parts. Width ranges from 0.097" to 0.100" (2.45mm to 2.54mm). Height ranges from 0.026" to 0.030" (0.65mm to 0.75mm). These variations are within standard 2010 package tolerances and do not affect PCB footprint compatibility.
