CSRF2010JK3L00 Equivalent & Substitute Parts

Part Overview

The CSRF2010JK3L00 is a 3 mOhms ±5% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This current sense resistor features metal foil composition with moisture resistance and operates across -55°C to 125°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRF2010JK3L00 is determined by the following critical parameters: resistance value (3 mOhms), package type (2010 / 5025 Metric), composition category (metal foil or metal element), and functional features (current sense, moisture resistant). All substitute parts maintain the same resistance value, package dimensions, and core functionality.

The substitute parts are grouped into two categories:

Direct Equivalent: CSRF2010JT3L00 maintains identical electrical and mechanical specifications with the exception of product status (Active vs. Obsolete).

Upgraded Alternatives: CSRF2010FT3L00 and CSNL2010FT3L00 offer improved tolerance and/or power ratings while maintaining package compatibility and core current sense functionality.

Parameter Comparison

Engineering Selection Recommendations

CSRF2010JT3L00 serves as the direct replacement for CSRF2010JK3L00. Both parts are electrically and mechanically identical with matching tolerance (±5%), power rating (1W), and operating temperature range (-55°C ~ 125°C). The primary distinction is product status: CSRF2010JT3L00 is Active, ensuring long-term availability and supply chain continuity.

CSRF2010FT3L00 provides an upgraded alternative with improved tolerance (±1% vs. ±5%) while maintaining identical power rating, package, and operating temperature specifications. This part is suitable for applications requiring tighter resistance tolerance.

CSNL2010FT3L00 offers the highest specification upgrade with ±1% tolerance and 1.5W power rating, along with extended operating temperature range (-55°C ~ 170°C). This part uses metal element composition instead of metal foil. Selection of this part is appropriate for applications requiring enhanced thermal performance or higher power dissipation capability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and current sense functionality required by the original design.

Frequently Asked Questions (FAQ)

Q: Can CSRF2010JT3L00 be used as a direct drop-in replacement for CSRF2010JK3L00?

A: Yes. CSRF2010JT3L00 is electrically and mechanically identical to CSRF2010JK3L00, with matching resistance (3 mOhms), tolerance (±5%), power rating (1W), package dimensions (2010 / 5025 Metric), and operating temperature range (-55°C ~ 125°C). The only difference is product status (Active vs. Obsolete).

Q: What are the differences between CSRF2010FT3L00 and CSRF2010JK3L00?

A: CSRF2010FT3L00 maintains the same resistance value, power rating, package, and operating temperature as CSRF2010JK3L00, but offers improved tolerance of ±1% compared to ±5%. Both use metal foil composition.

Q: When should CSNL2010FT3L00 be selected over other substitutes?

A: CSNL2010FT3L00 should be selected when the application requires higher power dissipation (1.5W vs. 1W), tighter tolerance (±1%), or extended operating temperature range (-55°C ~ 170°C). This part uses metal element composition and includes temperature coefficient specification (±50ppm/°C).

Q: Are all substitute parts compatible with the original 2010 package footprint?

A: All substitute parts use the 2010 (5025 Metric) package. Physical dimensions are nominally equivalent, though CSNL2010FT3L00 has slightly larger dimensions (0.200" L x 0.100" W vs. 0.197" L x 0.098" W) and greater seated height (0.041" vs. 0.037"). Verify PCB layout compatibility for CSNL2010FT3L00 in space-constrained applications.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original CSRF2010JK3L00 specifications.
