RC6432F2870CS 287 Ohm 1% 1W Chip Resistor 2512 Equivalent & Substitute Parts

Part Overview

The RC6432F2870CS is a 287 Ohm ±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 construction suitable for general industrial and commercial applications. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and termination count), and environmental operating parameters. Alternative sources become necessary when primary inventory is unavailable, supply chain constraints occur, or design requirements mandate specific manufacturer certifications such as AEC-Q200 automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2870CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 287 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Compatibility Requirements:

• Package type: 2512 (6432 metric) (exact match)
• Number of terminations: 2 (exact match)
• Composition: Thick film (exact match)

Compliance & Environmental Requirements:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH unaffected status (required)

All identified substitute parts meet these criteria. Additional qualifications such as AEC-Q200 automotive certification and product status (Active vs. Not For New Designs) are noted for design consideration but do not disqualify substitution based on core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC2512FK-07287RL (YAGEO), CRCW2512287RFKEG (Vishay Dale), and RMCF2512FT287R (Stackpole Electronics Inc) are recommended as primary alternatives. All three maintain Active product status, ensuring long-term availability and manufacturer support. These parts carry AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components. Dimensional variations are minimal and within standard PCB assembly tolerances for 2512 package components.

Secondary Substitute (Legacy Status):

ERJ-1TNF2870U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This designation indicates the manufacturer is phasing out this part number. Use this substitute only when existing inventory must be maintained or when design revisions are not feasible. New designs should transition to Active-status alternatives.

Compliance Verification:

All substitute parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited shelf life). No additional environmental or regulatory constraints apply to substitution decisions.

Frequently Asked Questions (FAQ)

Q: Can RC6432F2870CS be replaced with AC2512FK-07287RL in existing designs?

A: Yes. Both parts share identical electrical specifications (287 Ω ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (2512 package, 2 terminations). Dimensional differences (6.35 x 3.10mm vs. 6.30 x 3.20mm) are within standard PCB assembly tolerances. AC2512FK-07287RL adds AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications.

Q: What is the difference between CRCW2512287RFKEG and RMCF2512FT287R?

A: Both parts are electrically identical (287 Ω ±1%, 1W, ±100ppm/°C) and mechanically compatible (2512 package). Primary differences are manufacturer (Vishay Dale vs. Stackpole Electronics Inc) and minor dimensional variations in seated height (0.70mm vs. 0.70mm). Both carry AEC-Q200 certification and Active product status. Selection between these parts depends on supplier availability and established procurement relationships.

Q: Why is ERJ-1TNF2870U marked "Not For New Designs"?

A: "Not For New Designs" indicates Panasonic is discontinuing this part number. While electrically and mechanically equivalent to RC6432F2870CS, this status means the manufacturer will not guarantee long-term availability or support. Existing designs using this part may continue, but new designs should specify Active-status alternatives such as AC2512FK-07287RL, CRCW2512287RFKEG, or RMCF2512FT287R.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RC6432F2870CS and all identified substitutes (AC2512FK-07287RL, CRCW2512287RFKEG, ERJ-1TNF2870U, RMCF2512FT287R) are ROHS3 compliant with Moisture Sensitivity Level 1. No additional environmental qualification is required for substitution.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry standard for passive components. AC2512FK-07287RL, CRCW2512287RFKEG, ERJ-1TNF2870U, and RMCF2512FT287R all carry this certification, indicating enhanced reliability testing and quality assurance. RC6432F2870CS does not carry AEC-Q200 certification. For automotive applications, AEC-Q200 certified substitutes provide documented reliability performance.

Q: Can dimensional variations between substitute parts affect PCB assembly?

A: Dimensional variations among substitute parts are minimal. Length ranges from 6.30mm to 6.40mm, width from 3.10mm to 3.20mm, and height from 0.65mm to 0.70mm. These variations fall within standard PCB assembly tolerances for 2512 package components and do not require PCB redesign. Verify with your assembly partner if tight mechanical constraints exist in your specific application.
