Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRL2512FT1L00 is determined by the following critical parameters: resistance value (1 mOhm), tolerance (±1%), package type (2512), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 170°C), and compliance certifications (ROHS3, REACH Unaffected).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical and Mechanical Specifications): CSNL2512FT1L00 maintains identical resistance, tolerance, power rating, temperature coefficient, and operating range. Both parts use metal element composition and are packaged in 2512 format with equivalent moisture resistance.

Cross-Manufacturer Equivalents (Electrical Compatibility with Composition Variation): TLR3A20DR001FTDG and TLR3A30DR001FTDG from TE Connectivity Passive Product meet the core electrical requirements (1 mOhm, ±1%, ±50ppm/°C, -55°C ~ 170°C, 2512 package). These parts use metal foil composition instead of metal element. TLR3A20DR001FTDG maintains 2W power rating, while TLR3A30DR001FTDG provides 3W power rating.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and full ROHS3 compliance with REACH Unaffected designation. Selection between CSRL2512FT1L00 and CSNL2512FT1L00 is based on manufacturer preference and inventory availability, as both are Stackpole Electronics Inc products with identical electrical and mechanical specifications.

Selection of TE Connectivity parts (TLR3A20DR001FTDG or TLR3A30DR001FTDG) is appropriate when cross-manufacturer sourcing is required. TLR3A20DR001FTDG provides direct 2W power rating equivalence. TLR3A30DR001FTDG offers increased power dissipation capability at 3W while maintaining all other electrical parameters. The metal foil composition of TE Connectivity parts differs from the metal element composition of Stackpole parts but does not affect compliance or core electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CSNL2512FT1L00 be used as a direct replacement for CSRL2512FT1L00?

A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical resistance (1 mOhm), tolerance (±1%), power rating (2W), package (2512), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 170°C). Mechanical dimensions are equivalent within standard tolerances.

Q: What is the difference between metal element and metal foil composition in these current sense resistors?

A: Both compositions meet the specified electrical parameters (1 mOhm ±1%, ±50ppm/°C). Metal element and metal foil are different manufacturing technologies that achieve equivalent performance within the defined tolerance and temperature coefficient specifications.

Q: Can TLR3A30DR001FTDG (3W) replace CSRL2512FT1L00 (2W)?

A: Yes. TLR3A30DR001FTDG meets all electrical specifications of CSRL2512FT1L00 and provides additional power dissipation capability. The 3W rating is a superset of the 2W requirement and does not create incompatibility.

Q: Are all substitute parts packaged identically?

A: All parts use the 2512 (6432 Metric) package. Physical dimensions vary slightly: CSRL2512FT1L00 and TLR3A20DR001FTDG/TLR3A30DR001FTDG measure 0.256" L × 0.126" W, while CSNL2512FT1L00 measures 0.250" L × 0.125" W. These variations are within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All four parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All are active products with equivalent regulatory status.
