RC6432J150CS Chip Resistor 15Ω ±5% 1W 2512

Part Overview

The RC6432J150CS is a thick film chip resistor manufactured by Samsung Electro-Mechanics with a resistance of 15 Ohms at ±5% tolerance and 1W power rating in the 2512 (6432 Metric) package. This component is moisture resistant and maintains active product status with unlimited moisture sensitivity level (MSL 1), making it suitable for general industrial and consumer electronics applications. Alternative equivalent and substitute parts are necessary when Samsung Electro-Mechanics inventory is unavailable, when design specifications allow for improved tolerance or power ratings, or when automotive-qualified components are required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432J150CS are classified based on strict electrical and mechanical compatibility criteria. All substitute candidates maintain the following core requirements: identical 15 Ohms resistance value, 2512 (6432 Metric) package, thick film composition, -55°C to 155°C operating temperature range, ±100ppm/°C temperature coefficient, ROHS3 compliance, and MSL 1 moisture sensitivity.

Substitutes are differentiated by three primary variables: tolerance grade (±5% vs ±1%), power rating (1W vs 1.5W vs 2W), and special qualifications (standard industrial vs automotive AEC-Q200 rated). These parameters determine electrical performance and application suitability without affecting mechanical fit or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance & Power Rating): RC2512JK-0715RL from YAGEO is a direct functional equivalent to the RC6432J150CS with identical electrical specifications (15Ω ±5% 1W) and active product status. This part is suitable for applications where the ±5% tolerance and 1W power rating meet circuit requirements.

Tolerance Upgrade (±1% Grade): RC2512FK-0715RL (YAGEO), CRCW251215R0FKEG (Vishay Dale), and ERJ-1TNF15R0U (Panasonic) provide ±1% tolerance while maintaining 1W power rating and 2512 package compatibility. These parts are suitable for circuits where improved tolerance precision is required. CRCW251215R0FKEG includes AEC-Q200 automotive qualification, making it appropriate for automotive applications. ERJ-1TNF15R0U carries "Not For New Designs" status and should be avoided in new development efforts.

Power Rating Upgrade: RHC2512FT15R0 (Stackpole Electronics Inc) increases power rating to 2W while providing ±1% tolerance. This part accommodates higher dissipation applications within the same footprint and is suitable for designs with elevated thermal requirements.

Automotive Applications: CRCW251215R0FKEG and CRCW251215R0FKEGHP (both Vishay Dale) carry AEC-Q200 automotive qualifications. CRCW251215R0FKEGHP additionally provides pulse withstanding capability and 1.5W power rating for demanding automotive environments.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-0715RL directly replace RC6432J150CS in existing designs? A: Yes. RC2512JK-0715RL is electrically and mechanically identical with matching ±5% tolerance, 1W power rating, and 2512 package dimensions. No circuit modifications are required.

Q: What is the advantage of selecting a ±1% tolerance part? A: Parts with ±1% tolerance provide tighter resistance values compared to ±5% tolerance. This improves circuit accuracy in applications sensitive to component value variation, such as precision current limiting, timing circuits, or impedance matching networks.

Q: Can I use a 2W rated resistor in place of the 1W rated RC6432J150CS? A: Yes, if the circuit design allows. The RHC2512FT15R0 provides 2W capability within the same 2512 package footprint. Higher power rating creates thermal margin for applications approaching the 1W dissipation limit. No electrical modification is required.

Q: Are the physical dimensions between these 2512 parts interchangeable? A: Dimensions are equivalent for board layout purposes. All listed parts conform to 2512 (6432 Metric) specifications with length approximately 6.30-6.35mm, width approximately 3.10-3.20mm, and height approximately 0.65-0.70mm. Minor dimensional variations do not affect mechanical fit.

Q: Which substitute part is recommended for automotive applications? A: CRCW251215R0FKEG (Vishay Dale) is the primary choice for automotive applications requiring AEC-Q200 qualification with ±1% tolerance and 1W power rating. CRCW251215R0FKEGHP extends this qualification with pulse withstanding capability and 1.5W rating for enhanced automotive robustness.

Q: Why is ERJ-1TNF15R0U marked "Not For New Designs"? A: Parts with this status designation are in mature/declining phases of their lifecycle. While existing inventory supports field service and legacy platform maintenance, new product development should select alternatives with active product status to ensure long-term supply availability.

Q: Do all substitute parts meet ROHS3 compliance and MSL 1 requirements? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level) matching the primary RC6432J150CS specification. Compliance certifications and moisture handling requirements are equivalent across all candidates.
