Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RUK6432JR010CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 10 mOhms (exact match required)
• Power Rating: 1W (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Tolerance: ±5% (main part) to ±1% (substitute parts acceptable; tighter tolerance is compatible)
• Features: Current Sense, Moisture Resistant (main part) to Automotive AEC-Q200, High Voltage, or Moisture Resistant (substitute parts with different feature sets are acceptable if core electrical specifications match)

All five substitute parts meet the mandatory matching criteria. Tolerance variations and feature differences do not prevent substitution when core electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are electrically and mechanically compatible with the RUK6432JR010CS based on matching core specifications. Selection among substitutes should be based on the following factors:

Tolerance Requirements:

• CRCW251210M0FKEG, RC2512FK-0710ML, and RMCF2512FT10M0 offer ±1% tolerance, providing tighter resistance accuracy compared to the ±5% specification of the main part and HVC2512T1005JET / RC2512JK-0710ML.

Compliance and Certifications:

• CRCW251210M0FKEG and RMCF2512FT10M0 carry Automotive AEC-Q200 qualification, suitable for automotive applications.
• HVC2512T1005JET is specified for high voltage applications.
• RC2512FK-0710ML and RC2512JK-0710ML are specified with moisture resistant characteristics matching the original part feature set.

Inventory Availability:

• CRCW251210M0FKEG: 51,662 pcs
• RMCF2512FT10M0: 15,685 pcs
• RC2512FK-0710ML: 10,771 pcs
• RC2512JK-0710ML: 8,837 pcs
• HVC2512T1005JET: 1,289 pcs

Product Status: All substitute parts are Active status, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can CRCW251210M0FKEG replace RUK6432JR010CS in a current sense application?

A: Yes. CRCW251210M0FKEG meets all mandatory electrical and mechanical specifications. The ±1% tolerance provides tighter accuracy than the ±5% specification of the original part. The Automotive AEC-Q200 qualification does not prevent use in non-automotive applications.

Q: What is the difference between RC2512FK-0710ML and RC2512JK-0710ML?

A: Both parts are manufactured by YAGEO in the RC_L series with identical mechanical dimensions and electrical specifications. The primary difference is tolerance: RC2512FK-0710ML is ±1% while RC2512JK-0710ML is ±5%. Both are moisture resistant and compatible with the original part.

Q: Is HVC2512T1005JET suitable for standard current sense applications?

A: Yes. HVC2512T1005JET meets all core electrical and mechanical requirements. The high voltage feature designation indicates additional capability but does not restrict use in standard applications. The ±5% tolerance matches the original part specification.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All five substitute parts are supplied in Tape & Reel (TR) packaging. The original RUK6432JR010CS is supplied in bulk packaging. Tape & Reel packaging is standard for automated assembly processes.

Q: Do substitute parts with AEC-Q200 qualification cost more?

A: Cost information is not provided in the technical specifications. CRCW251210M0FKEG and RMCF2512FT10M0 carry AEC-Q200 qualification. Procurement should contact suppliers for pricing.

Q: Can I use RMCF2512FT10M0 in place of RUK6432JR010CS?

A: Yes. RMCF2512FT10M0 is fully compatible. It offers ±1% tolerance and Automotive AEC-Q200 qualification. Mechanical dimensions are identical to the original part (0.248" L x 0.126" W).

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts, including the original and substitutes, carry this rating.
