Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432J110CS is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 11 Ohms
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3

Tolerance Consideration: Substitute parts with tolerance of ±1% meet or exceed the ±5% specification of the main part and are classified as direct substitutes. Parts with ±5% tolerance are classified as direct equivalents.

Dimensional Tolerance: Physical dimensions (length, width, height) may vary within manufacturing tolerances while maintaining 2512 package classification and PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance): RC2512JK-0711RL (YAGEO) is a direct equivalent to RC6432J110CS. Both parts share identical electrical specifications (11 Ohms ±5%, 1W) and environmental ratings. YAGEO RC2512JK-0711RL is in active production status with higher inventory availability (3565 pieces). Selection of this substitute is appropriate for applications where the ±5% tolerance specification is the design requirement.

Direct Substitute (Enhanced Tolerance): CRCW251211R0FKEG (Vishay Dale) and ERJ-1TNF11R0U (Panasonic) are direct substitutes with improved tolerance specification (±1% versus ±5%). Both parts meet all electrical and environmental parameters of the main part. CRCW251211R0FKEG is in active production status. ERJ-1TNF11R0U carries a "Not For New Designs" status, indicating this part is in mature phase and should not be selected for new circuit designs.

Compliance and Certifications: All four parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating. CRCW251211R0FKEG and ERJ-1TNF11R0U include AEC-Q200 automotive qualification, providing additional reliability assurance for automotive applications.

Production Status Consideration: For new designs, select from parts with "Active" status: RC6432J110CS (Samsung), RC2512JK-0711RL (YAGEO), or CRCW251211R0FKEG (Vishay Dale). Avoid ERJ-1TNF11R0U due to "Not For New Designs" designation.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-0711RL replace RC6432J110CS directly on the PCB? A: Yes. Both parts are 2512 (6432 Metric) package with identical footprint dimensions within manufacturing tolerance. Electrical specifications (11 Ohms ±5%, 1W) are identical. Direct PCB substitution is supported.

Q: What is the difference between the ±5% and ±1% tolerance parts? A: The RC6432J110CS and RC2512JK-0711RL specify ±5% tolerance, meaning the actual resistance value can vary by up to 5% from the nominal 11 Ohms. CRCW251211R0FKEG and ERJ-1TNF11R0U specify ±1% tolerance, providing tighter resistance accuracy. Parts with ±1% tolerance meet the ±5% specification and can substitute for ±5% parts in any application.

Q: Are there packaging differences between these parts? A: RC6432J110CS is supplied in bulk packaging. RC2512JK-0711RL, CRCW251211R0FKEG, and ERJ-1TNF11R0U are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. Bulk packaging may require manual handling or reeling for automated placement.

Q: Why is ERJ-1TNF11R0U marked "Not For New Designs"? A: This designation indicates the part is in mature production phase and the manufacturer recommends against selecting it for new circuit designs. Existing designs using this part may continue to source it, but new designs should select from actively promoted alternatives such as CRCW251211R0FKEG or RC2512JK-0711RL.

Q: Do all substitute parts have the same operating temperature range? A: Yes. All four parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient. Operating temperature range and thermal characteristics are identical across all listed parts.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the lowest moisture sensitivity level. Parts with MSL 1 have unlimited shelf life and do not require special moisture-controlled storage or handling. All listed parts carry MSL 1 rating.

Q: Are all parts ROHS3 compliant? A: Yes. RC6432J110CS, RC2512JK-0711RL, CRCW251211R0FKEG, and ERJ-1TNF11R0U are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
