RC6432F7151CS 7.15 kOhms ±1% 1W Chip Resistor 2512 Equivalent & Substitute Parts

Part Overview

The RC6432F7151CS is a 7.15 kOhms ±1% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with moisture resistant characteristics and unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, suitable for general industrial and commercial applications requiring precision resistive elements with moderate power dissipation.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package type, dimensions, termination count). Substitute components may differ in manufacturer-specific features such as automotive qualification levels or packaging formats while maintaining functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F7151CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 7.15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

Mechanical Equivalence Requirements:

• Package type: 2512 (6432 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: Compatible within standard package tolerances

Compliance Requirements:

• RoHS3 compliance (required for direct substitution)
• REACH unaffected status (required for direct substitution)
• Moisture sensitivity level: MSL 1 or equivalent (required)

Identified substitute parts meet all electrical and mechanical equivalence criteria. Differences in manufacturer-specific features (such as automotive AEC-Q200 qualification or packaging format) do not affect functional substitutability in applications where such certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

CRCW25127K15FKEG (Vishay Dale) is the primary substitute for RC6432F7151CS. This part maintains Active product status, meets all electrical and mechanical equivalence criteria, and includes automotive AEC-Q200 qualification. The Tape & Reel packaging format provides advantages for high-volume manufacturing environments. Physical dimensions remain within standard 2512 package tolerances. This substitute is suitable for direct replacement in new designs and production applications.

ERJ-1TNF7151U (Panasonic Electronic Components) is a secondary substitute that meets all electrical and mechanical equivalence requirements. However, this part carries "Not For New Designs" product status, indicating manufacturer discontinuation or transition planning. While functionally equivalent and currently in stock, this substitute should be reserved for legacy system maintenance, repair applications, or situations where existing design validation has been completed. New design implementations should prioritize the CRCW25127K15FKEG substitute or the original RC6432F7151CS component.

Both substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity level, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can CRCW25127K15FKEG replace RC6432F7151CS in existing circuit designs?

A: Yes. CRCW25127K15FKEG is electrically and mechanically equivalent to RC6432F7151CS. Both components share identical resistance (7.15 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 2512 package type. Physical dimensions are within standard package tolerances. The substitute maintains ROHS3 compliance and MSL 1 rating.

Q: What is the difference between the packaging formats listed for these parts?

A: RC6432F7151CS is supplied in bulk packaging format, while CRCW25127K15FKEG and ERJ-1TNF7151U are supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly processes and high-volume production. Bulk packaging is suitable for manual assembly or lower-volume applications. The electrical and mechanical properties of the components are identical regardless of packaging format.

Q: Why is ERJ-1TNF7151U marked as "Not For New Designs"?

A: "Not For New Designs" product status indicates that the manufacturer (Panasonic) is transitioning this component out of active production. While ERJ-1TNF7151U remains functionally equivalent and currently available in inventory, it should not be selected for new circuit designs. This status is a manufacturer lifecycle indicator and does not reflect component performance or reliability. Existing designs using this part may continue operation without modification.

Q: Are there dimensional differences between the substitute parts that affect PCB layout?

A: Minor dimensional variations exist within standard 2512 package tolerances. RC6432F7151CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" maximum seated height. CRCW25127K15FKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" maximum seated height. ERJ-1TNF7151U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.028" maximum seated height. These variations fall within standard 2512 package specifications and do not require PCB layout modifications for direct substitution.

Q: Do the substitute parts require different soldering or assembly procedures?

A: No. All substitute parts use identical 2-terminal configurations and standard thick film chip resistor construction. Soldering temperature profiles, reflow parameters, and assembly procedures remain unchanged. Tape & Reel packaged substitutes (CRCW25127K15FKEG and ERJ-1TNF7151U) are compatible with standard pick-and-place equipment used for bulk-packaged components.

Q: What compliance certifications apply to all listed parts?

A: All parts (RC6432F7151CS, CRCW25127K15FKEG, and ERJ-1TNF7151U) are ROHS3 compliant and REACH unaffected. All parts carry ECCN classification EAR99 and HTSUS code 8533.21.0030. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage or handling.
