Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FT10L0 is determined by the following critical parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 2512 (6432 Metric)
• Automotive qualification: AEC-Q200
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The PMR100HZPFU10L0 from Rohm Semiconductor meets all critical electrical and mechanical requirements. While composition differs (metal element versus thick film) and temperature coefficient is superior (±100ppm/°C versus ±200ppm/°C), both parts satisfy the specified parameter envelope for current sense applications in automotive environments.

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2512FT10L0 and PMR100HZPFU10L0 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

• Supply availability: Rohm PMR100HZPFU10L0 has higher inventory (5130 units) compared to Stackpole CSRN2512FT10L0 (689 units)
• Temperature stability: Rohm part offers superior temperature coefficient (±100ppm/°C) for applications requiring tighter performance across thermal extremes
• Physical dimensions: Rohm part is slightly larger in footprint but lower in profile, which may affect PCB layout and thermal management considerations
• Composition: Metal element construction in Rohm part provides different thermal and frequency response characteristics compared to thick film construction

Frequently Asked Questions (FAQ)

Q: Can PMR100HZPFU10L0 be used as a direct replacement for CSRN2512FT10L0?

A: Yes. Both parts share identical resistance (10 mOhms), tolerance (±1%), power rating (2W), package designation (2512), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. Physical dimensions differ slightly but remain within the 2512 package specification envelope.

Q: What is the difference in composition between these parts?

A: CSRN2512FT10L0 uses thick film construction, while PMR100HZPFU10L0 uses metal element construction. Both compositions are suitable for current sense applications and meet the specified electrical parameters.

Q: Does the temperature coefficient difference affect substitution?

A: The Rohm part exhibits a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C). This represents improved stability across the operating temperature range and does not prevent substitution; it may enhance performance in temperature-sensitive applications.

Q: Are there PCB layout considerations when switching between these parts?

A: The Rohm PMR100HZPFU10L0 is slightly larger in footprint (0.252" × 0.126" versus 0.250" × 0.124") but lower in profile (0.019" versus 0.028"). Verify PCB pad spacing and clearance requirements before implementation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry MSL 1 rating, and hold AEC-Q200 automotive qualification.
