CSR2512FT10L0 Equivalent & Substitute Parts

Part Overview

The CSR2512FT10L0 is a 10 mOhms ±1% 2W chip resistor in 2512 (6432 Metric) package manufactured by Stackpole Electronics Inc. This thick film current sense resistor is designed for precision current measurement applications requiring low resistance values with tight tolerance specifications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and operational specifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR2512FT10L0 are qualified based on the following critical parameters:

Electrical equivalence requires matching resistance value (10 mOhms), tolerance (±1%), and power rating (2W). Mechanical compatibility is ensured through identical package designation (2512 / 6432 Metric). Operating temperature range (-55°C ~ 155°C) and moisture sensitivity level (MSL 1) must be maintained. RoHS3 compliance is mandatory for all substitutes.

The CSR2512FT10L0 is classified as a standard thick film current sense resistor without automotive qualification. Substitute parts may include enhanced versions with automotive AEC-Q200 certification or alternative compositions (metal element) provided all core electrical and mechanical parameters remain equivalent.

Engineering Selection Recommendations

CSRN2512FK10L0 serves as a direct substitute for applications requiring automotive-grade qualification. This part maintains identical electrical specifications and thick film composition while adding AEC-Q200 certification. Selection is appropriate for automotive current sensing circuits where enhanced reliability standards are mandated.

PMR100HZPFU10L0 represents an alternative from Rohm Semiconductor with improved temperature coefficient performance (±100ppm/°C versus ±200ppm/°C). The metal element composition provides superior thermal stability. This part carries AEC-Q200 certification and is suitable for precision current measurement applications in automotive environments where tighter temperature coefficient tolerance is beneficial.

For non-automotive applications without specific AEC-Q200 requirements, the original CSR2512FT10L0 remains the baseline selection. Substitution to automotive-qualified variants is permissible when design specifications do not restrict manufacturer selection or composition type.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FK10L0 replace CSR2512FT10L0 in non-automotive applications?

A: Yes. CSRN2512FK10L0 maintains identical electrical parameters (10 mOhms ±1%, 2W) and mechanical compatibility (2512 package). The addition of AEC-Q200 certification does not restrict use in standard industrial applications. Both parts are thick film composition with matching temperature coefficients and operating ranges.

Q: What is the primary difference between PMR100HZPFU10L0 and the Stackpole alternatives?

A: PMR100HZPFU10L0 uses metal element composition instead of thick film, resulting in a superior temperature coefficient of ±100ppm/°C compared to ±200ppm/°C. This provides improved stability across the -55°C to 155°C operating range. The metal element construction also yields a lower seated height (0.019" versus 0.026-0.028"). Electrical resistance and tolerance remain equivalent.

Q: Are all three parts mechanically interchangeable?

A: All three parts use the 2512 (6432 Metric) package with identical footprints. Seated heights vary slightly (0.026" for CSR2512FT10L0, 0.028" for CSRN2512FK10L0, 0.019" for PMR100HZPFU10L0), which is within standard PCB assembly tolerances and does not affect mechanical interchangeability.

Q: Which substitute is recommended for high-precision current measurement?

A: PMR100HZPFU10L0 is preferred for applications requiring maximum accuracy over temperature due to its ±100ppm/°C temperature coefficient and metal element construction. This composition provides superior long-term stability compared to thick film alternatives.

Q: Do all substitutes maintain RoHS3 and MSL 1 compliance?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are maintained across all substitutes.
