Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSRF2512FK5L00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 2512 (6432 Metric)
• Composition: Metal Foil
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive qualification: AEC-Q200
• Compliance: ROHS3, REACH Unaffected

The CSRF2512FT5L00 meets all electrical and mechanical specifications identical to the main part. The only difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CSRF2512FT5L00 is the direct equivalent for the obsolete CSRF2512FK5L00. Both parts are manufactured by Stackpole Electronics Inc within the same CSRF series and share identical electrical specifications, mechanical dimensions, and automotive qualifications.

The CSRF2512FT5L00 is currently in active production with substantial inventory availability (43,271 pcs), whereas the CSRF2512FK5L00 is obsolete. For new designs and ongoing procurement, the CSRF2512FT5L00 is the appropriate selection. The packaging difference (Tape & Reel format) does not impact electrical performance or circuit functionality.

Both parts maintain full compliance with ROHS3 and REACH requirements, with identical moisture sensitivity ratings and temperature operating ranges suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can CSRF2512FT5L00 be used as a direct replacement for CSRF2512FK5L00?

A: Yes. The CSRF2512FT5L00 is electrically and mechanically identical to the CSRF2512FK5L00. All critical parameters including resistance, tolerance, power rating, package dimensions, and automotive qualifications are equivalent.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. The CSRF2512FK5L00 uses bulk packaging, while the CSRF2512FT5L00 is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not alter electrical characteristics or performance.

Q: Is the CSRF2512FT5L00 suitable for automotive applications?

A: Yes. The CSRF2512FT5L00 carries AEC-Q200 qualification and is rated for automotive use across the operating temperature range of -55°C to 170°C, identical to the original part.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: Why is the CSRF2512FK5L00 listed as obsolete?

A: The CSRF2512FK5L00 has been discontinued by the manufacturer. The CSRF2512FT5L00 remains in active production and serves as the current equivalent for this resistance value and specification set.
