RC6432J111CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432J111CS is a 110 Ohms ±5% 1W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The part is suitable for general-purpose applications requiring moisture-resistant thick film construction across the -55°C to 155°C operating temperature range.

Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, performance upgrades, or when primary sourcing becomes constrained. Substitute selection is determined by matching critical electrical parameters: resistance value, power rating, package dimensions, and operating temperature range.

Substitute Part Grouping Explanation

Substitute parts for the RC6432J111CS are classified into two categories based on allowed parameter variations:

Direct Equivalent (Tolerance Match): RC2512JK-07110RL (YAGEO) maintains identical electrical specifications: 110 Ohms ±5% tolerance, 1W power rating, and 2512 package. This part is a direct functional replacement with no performance trade-offs.

Upgraded Substitutes (Tighter Tolerance): RC2512FK-07110RL (YAGEO), CRCW2512110RFKEG (Vishay Dale), ERJ-1TNF1100U (Panasonic), and RMCF2512FT110R (Stackpole) all feature ±1% tolerance instead of ±5%. These parts maintain identical resistance value, power rating, package, and temperature range. The tolerance upgrade represents improved precision without changing functional compatibility. CRCW2512110RFKEG, ERJ-1TNF1100U, and RMCF2512FT110R additionally carry AEC-Q200 automotive qualification.

All substitute parts share the following critical parameters with the main part:

• Resistance: 110 Ohms
• Power Rating: 1W
• Package: 2512 (6432 Metric)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C to 155°C
• Composition: Thick Film
• RoHS3 Compliance
• MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes): RC2512JK-07110RL is the primary equivalent substitute. It maintains the ±5% tolerance specification of the original RC6432J111CS while offering active product status and full availability. This part is selected when tolerance requirements remain unchanged and sourcing of the Samsung part becomes unavailable.

For Tolerance-Relaxed Applications: RC2512FK-07110RL, CRCW2512110RFKEG, and RMCF2512FT110R are suitable when circuit design permits ±1% tolerance. These parts provide improved precision over the original ±5% specification. CRCW2512110RFKEG and RMCF2512FT110R carry AEC-Q200 automotive qualification and maintain Active product status, making them preferred for automotive or high-reliability applications.

For Legacy System Maintenance: ERJ-1TNF1100U is available with AEC-Q200 qualification but carries "Not For New Designs" status. This part is restricted to replacement applications in existing systems and should not be selected for new designs.

Compliance Verification: All substitute parts maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status identical to the original part. No additional compliance documentation is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-07110RL replace RC6432J111CS without circuit redesign?

A: Yes. RC2512JK-07110RL is a direct equivalent with identical electrical specifications: 110 Ohms ±5% tolerance, 1W power rating, 2512 package, and -55°C to 155°C operating range. No circuit modifications are required.

Q: What is the difference between the ±5% and ±1% tolerance substitutes?

A: The ±1% tolerance substitutes (RC2512FK-07110RL, CRCW2512110RFKEG, ERJ-1TNF1100U, RMCF2512FT110R) provide tighter resistance tolerance compared to the original ±5% specification. This represents improved precision. All other electrical parameters remain identical. Selection depends on circuit tolerance requirements.

Q: Are the 2512 package dimensions identical across all substitute parts?

A: The 2512 (6432 Metric) package is standardized across all parts listed. Dimensional variations are minor and within standard PCB footprint tolerances. All parts are mechanically compatible with the same PCB layout.

Q: Which substitute part is recommended for automotive applications?

A: CRCW2512110RFKEG (Vishay Dale) and RMCF2512FT110R (Stackpole Electronics) both carry AEC-Q200 automotive qualification with Active product status. Either part is suitable for automotive circuit requirements.

Q: Why is ERJ-1TNF1100U marked "Not For New Designs"?

A: ERJ-1TNF1100U carries "Not For New Designs" status, indicating the manufacturer has discontinued active development for this part. It remains available for replacement in existing systems but should not be selected for new product designs. Use CRCW2512110RFKEG or RMCF2512FT110R as alternatives.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating identical to the original RC6432J111CS. No additional environmental qualification is required.

Q: Can I use a ±1% tolerance part in a circuit designed for ±5% tolerance?

A: Yes. A ±1% tolerance part is a performance upgrade and is compatible with any circuit designed for ±5% tolerance. The tighter tolerance provides improved accuracy without introducing incompatibility.
