Substitute Part Grouping Explanation

The CSRN2512FK30L0 qualifies as a substitute for the CSRN2512JK30L0 based on the following criteria:

Identical Parameters:

• Resistance value: 30 mOhms
• Power rating: 2W
• Package / Case: 2512 (6432 Metric)
• Physical dimensions: 0.250" L x 0.124" W (6.35mm x 3.15mm)
• Height - Seated (Max): 0.028" (0.70mm)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Manufacturer: Stackpole Electronics Inc
• Series: CSRN

Differing Parameters:

• Tolerance: ±1% (substitute) vs. ±5% (main part) — tighter tolerance
• Packaging: Cut Tape (CT) & Digi-Reel® (substitute) vs. Tape & Reel (TR) (main part)

The substitute part offers improved tolerance specification while maintaining all critical electrical and mechanical characteristics required for automotive current sense applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512JK30L0 and CSRN2512FK30L0 are active production parts from Stackpole Electronics Inc with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application tolerance requirements and packaging logistics:

The CSRN2512JK30L0 with ±5% tolerance is suitable for applications where standard tolerance specifications are acceptable. The CSRN2512FK30L0 with ±1% tolerance provides tighter resistance accuracy for precision current sensing circuits where lower tolerance stack-up is required. Both parts maintain identical thermal characteristics, power ratings, and operating temperature ranges, ensuring functional equivalence in automotive current sense applications. Packaging format differences (Tape & Reel vs. Cut Tape & Digi-Reel) affect supply chain and assembly processes but do not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FK30L0 directly replace CSRN2512JK30L0 in existing designs?

A: Yes. The substitute part maintains identical resistance value, power rating, package dimensions, thermal characteristics, and automotive qualification. The tighter ±1% tolerance of the substitute part is a functional improvement over the ±5% specification of the original part.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs: CSRN2512JK30L0 has ±5% tolerance while CSRN2512FK30L0 has ±1% tolerance. Packaging format also differs (Tape & Reel vs. Cut Tape & Digi-Reel), but this affects supply and assembly only, not electrical performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive use across the -55°C to 155°C operating temperature range.

Q: Does the packaging difference affect circuit performance?

A: No. Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) is a supply and assembly consideration only. It does not affect electrical characteristics, thermal performance, or mechanical fit on the PCB.

Q: Which part should be selected for high-precision current sensing?

A: The CSRN2512FK30L0 with ±1% tolerance is preferred for applications requiring tighter resistance accuracy and lower tolerance stack-up in precision current sensing circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both CSRN2512JK30L0 and CSRN2512FK30L0 are ROHS3 compliant with MSL rating of 1 (Unlimited).
