Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSRF2512JTR100 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 100 mOhms
• Power rating: 2W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 170°C
• Automotive qualification: AEC-Q200

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Packaging format: Tape & Reel (TR)

Allowable Variations:

• Tolerance: May be tighter (±1%) than the original ±5%
• Composition: Metal Foil or Metal Film acceptable
• Manufacturer: Different qualified manufacturers permitted

Two substitute parts meet these criteria: CSRF2512FTR100 (Stackpole, tolerance upgrade to ±1%) and PE2512FKE7W0R1L (YAGEO, tolerance upgrade to ±1% with metal film composition).

Parameter Comparison

Engineering Selection Recommendations

CSRF2512FTR100 (Stackpole Electronics Inc): This part is a direct upgrade from CSRF2512JTR100, maintaining identical composition (metal foil), manufacturer, and all electrical specifications while improving tolerance from ±5% to ±1%. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Selection is appropriate when tighter tolerance specifications are required without changing component sourcing or thermal characteristics.

PE2512FKE7W0R1L (YAGEO): This part provides equivalent electrical performance and automotive qualification with ±1% tolerance. The primary difference is metal film composition versus metal foil. Both parts maintain identical power rating, temperature coefficient, operating range, and package dimensions. Selection is appropriate when YAGEO sourcing is preferred or when metal film composition meets circuit requirements.

All three parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility in automotive current sense applications.

Frequently Asked Questions (FAQ)

Q: Can CSRF2512FTR100 directly replace CSRF2512JTR100? A: Yes. Both parts are identical in all electrical and mechanical parameters except tolerance. CSRF2512FTR100 provides ±1% tolerance versus ±5% in the original part, making it a direct upgrade suitable for any application using CSRF2512JTR100.

Q: What is the difference between metal foil and metal film composition in these resistors? A: Both compositions meet the specified electrical parameters for this application. Metal foil (CSRF series) and metal film (PE2512FKE7W0R1L) provide equivalent performance in 2W 100 mOhms current sense applications. Composition selection depends on circuit design requirements and supplier availability.

Q: Are all substitute parts automotive qualified? A: Yes. CSRF2512JTR100, CSRF2512FTR100, and PE2512FKE7W0R1L all carry AEC-Q200 automotive qualification, suitable for automotive current sense applications.

Q: Can I use PE2512FKE7W0R1L in place of CSRF2512JTR100? A: Yes. PE2512FKE7W0R1L meets all electrical and mechanical requirements. The part maintains 100 mOhms resistance, 2W power rating, ±50ppm/°C temperature coefficient, -55°C to 170°C operating range, and AEC-Q200 qualification. Physical dimensions are within acceptable tolerance (6.35mm x 3.18mm versus 6.45mm x 3.25mm).

Q: What is the significance of MSL 1 rating? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All three parts carry this rating, eliminating moisture-related storage constraints.

Q: Are these parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
