Parameter Comparison

Engineering Selection Recommendations

CSRF2512FT25L0 (Stackpole Electronics Inc): This substitute provides identical electrical and mechanical specifications to the CSRF2512JT25L0 with the advantage of tighter tolerance (±1% versus ±5%). Both parts are manufactured by Stackpole Electronics Inc and share identical composition (Metal Foil), temperature characteristics, and automotive qualification. Selection of this part is appropriate when improved tolerance performance is required without changing supplier or composition type. Inventory availability is comparable at 1003 units.

PE2512FKE7W0R025L (YAGEO): This substitute meets all electrical and mechanical requirements with ±1% tolerance and maintains AEC-Q200 automotive qualification. The primary difference is composition (Metal Film versus Metal Foil) and manufacturer (YAGEO versus Stackpole). Physical dimensions show minor variations within package tolerance (0.250" L x 0.125" W versus 0.254" L x 0.128" W; height 0.035" versus 0.037"). This part is suitable for applications where supplier diversification or metal film composition is acceptable. Significantly higher inventory availability (13447 units) may provide supply chain advantages.

Frequently Asked Questions (FAQ)

Q: Can CSRF2512FT25L0 be used as a direct replacement for CSRF2512JT25L0?

A: Yes. Both parts share identical resistance (25 mOhms), power rating (2W), package (2512), temperature range (-55°C ~ 170°C), and AEC-Q200 qualification. The CSRF2512FT25L0 provides tighter tolerance (±1% versus ±5%), making it a direct upgrade with no design modifications required.

Q: What is the difference between Metal Foil and Metal Film composition in the PE2512FKE7W0R025L?

A: Both compositions meet the specified electrical parameters for this application. Metal Foil (CSRF series) and Metal Film (PE series) differ in manufacturing process and internal structure but deliver identical resistance value, tolerance, temperature coefficient, and power rating. Selection between them depends on application-specific requirements not specified in the electrical parameters.

Q: Are the physical dimension differences between CSRF2512JT25L0 and PE2512FKE7W0R025L significant?

A: The dimensional variations (0.254" L x 0.128" W x 0.037" H versus 0.250" L x 0.125" W x 0.035" H) fall within standard 2512 package tolerance. Both parts are mechanically compatible with 2512 footprints. PCB layout and thermal management considerations should be evaluated for specific applications.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. CSRF2512FT25L0 and PE2512FKE7W0R025L both carry AEC-Q200 qualification, meeting automotive reliability and qualification standards identical to the CSRF2512JT25L0.

Q: Which substitute part should be selected for supply chain continuity?

A: PE2512FKE7W0R025L offers the highest inventory availability (13447 units) compared to CSRF2512JT25L0 (1013 units) and CSRF2512FT25L0 (1003 units). For applications requiring extended supply assurance, the YAGEO part provides greater stock depth.

Q: Are all parts RoHS3 compliant?

A: Yes. CSRF2512JT25L0, CSRF2512FT25L0, and PE2512FKE7W0R025L are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements.
