RC6432F1333CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1333CS is a 133 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1333CS are identified based on strict alignment of the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 133 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Compatibility Requirements:

• Package format: 2512 (6432 Metric)
• Physical dimensions within acceptable tolerance
• Two terminations (standard for chip resistors)

Compliance & Environmental Requirements:

• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status
• Thick film composition

The CRCW2512133KFKEG manufactured by Vishay Dale meets all these criteria and qualifies as a direct substitute. This part maintains identical electrical specifications, operates within the same temperature range, and shares the same package designation. The primary distinction is the inclusion of AEC-Q200 automotive qualification in the Vishay part, which represents an additional certification level beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

The CRCW2512133KFKEG from Vishay Dale is a qualified substitute for the RC6432F1333CS. Both components are in active production status and maintain ROHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Selection Basis:

The substitution is valid based on:

• Complete electrical parameter equivalence (resistance, tolerance, power rating, temperature coefficient)
• Identical operating temperature range (-55°C to 155°C)
• Mechanical compatibility within the 2512 (6432 Metric) package format
• Dimensional variations (width and height) fall within acceptable manufacturing tolerances for chip resistor applications
• Equivalent compliance certifications (ROHS3, REACH unaffected)

The Vishay part includes AEC-Q200 automotive qualification, which represents an enhanced reliability standard. This additional certification does not create incompatibility; rather, it indicates the Vishay component meets a higher qualification threshold suitable for automotive applications while remaining fully compatible with general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512133KFKEG directly replace the RC6432F1333CS in existing designs?

A: Yes. Both components share identical electrical specifications (133 kOhms ±1%, 1W, ±100ppm/°C) and operate across the same temperature range (-55°C to 155°C). The 2512 package format is identical, and dimensional variations are within standard manufacturing tolerances for chip resistors.

Q: What is the significance of the AEC-Q200 certification on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. This certification does not restrict the part to automotive use; it indicates the component meets enhanced reliability requirements and is suitable for both automotive and general-purpose applications.

Q: Are there packaging differences between these two parts?

A: The RC6432F1333CS is supplied in standard packaging, while the CRCW2512133KFKEG is supplied in Tape & Reel (TR) format. Both use the identical 2512 (6432 Metric) package case. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating unlimited shelf life under normal storage conditions without moisture bake-out requirements.

Q: Are the physical dimensions identical?

A: The length is identical at 0.248" (6.30mm). Width and height show minor variations: the Vishay part is 0.002" (0.05mm) narrower and 0.002" (0.04mm) taller. These variations are within standard manufacturing tolerances for thick film chip resistors and do not affect PCB layout or assembly compatibility.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected. Both carry unlimited moisture sensitivity level (MSL 1) ratings.
