CSR0805FTR250 Equivalent & Substitute Parts

Part Overview

The CSR0805FTR250 is a 250 mOhms ±1% thick film chip resistor in 0805 (2012 Metric) package format, rated for 0.25W power dissipation. Designed for current sense applications, this component is actively manufactured by Stackpole Electronics Inc and maintains ROHS3 compliance. Substitute parts are identified to provide design flexibility and supply chain continuity when the primary part number becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FTR250 is determined by strict equivalence across the following critical parameters:

• Resistance value: 250 mOhms
• Tolerance: ±1%
• Power rating: 0.25W
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Application class: Current Sense
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Regulatory compliance: ROHS3 Compliant

Only parts matching all specified parameters are classified as direct substitutes. The CSR0805FKR250 meets these criteria and is listed as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both CSR0805FTR250 and CSR0805FKR250 are active products manufactured by Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts may be based on packaging format (Tape & Reel for both) and inventory availability. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The CSR0805FKR250 carries significantly higher inventory levels (308,959 pcs vs. 1,147 pcs), making it the preferred choice for supply chain continuity in high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can CSR0805FKR250 be used as a direct replacement for CSR0805FTR250?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc and share identical electrical specifications (250 mOhms ±1%, 0.25W), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and regulatory compliance (ROHS3, REACH Unaffected). No circuit redesign or board layout modification is required.

Q: Are there differences in packaging between these two part numbers?

A: Both parts are supplied in Tape & Reel (TR) format. No packaging differences exist between CSR0805FTR250 and CSR0805FKR250.

Q: What determines substitution eligibility for 0805 current sense resistors?

A: Substitution requires exact matching of resistance value (250 mOhms), tolerance (±1%), power rating (0.25W), package format (0805), composition (Thick Film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). Deviations in any parameter disqualify a part as a direct substitute.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both CSR0805FTR250 and CSR0805FKR250 operate across the -55°C ~ 155°C temperature range with a temperature coefficient of ±200ppm/°C, supporting applications requiring extended thermal performance.

Q: What is the moisture sensitivity classification for these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.
