Substitute Part Grouping Explanation

Substitution of the PCF2C3R3K is based on strict equivalence of all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is the packaging format used for supply and distribution.

Key Parameters Determining Substitutability:

• Resistance value: 3.3 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package case: Axial
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C ~ 200°C
• Temperature coefficient: -500/-1300ppm/°C
• Automotive qualification: AEC-Q200
• Features: Flame Proof, Safety, Non-Inductive, Pulse Withstanding
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part PCF2CT631R3R3K maintains identical electrical performance and physical specifications. The only difference is the supply packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats contain the same component with no functional differences.

Parameter Comparison

Engineering Selection Recommendations

Both the PCF2C3R3K and PCF2CT631R3R3K are active production components from KOA Speer Electronics, Inc., with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on procurement and assembly requirements rather than electrical performance, as all functional parameters are identical.

PCF2C3R3K (Tape & Reel format) is appropriate for high-volume automated assembly operations where tape-and-reel packaging integrates directly with pick-and-place equipment.

PCF2CT631R3R3K (Cut Tape format) is appropriate for lower-volume applications, manual assembly processes, or situations where smaller quantity increments are required. This substitute currently has higher inventory availability at 1390 pieces compared to 744 pieces for the main part.

Both parts maintain identical electrical characteristics across the full operating temperature range of -40°C to 200°C and deliver the same pulse-withstanding performance required in automotive circuits.

Frequently Asked Questions (FAQ)

Q: Are PCF2C3R3K and PCF2CT631R3R3K electrically identical?

A: Yes. Both parts have identical resistance (3.3 Ohms), tolerance (±10%), power rating (2W), temperature coefficient (-500/-1300ppm/°C), and operating range (-40°C ~ 200°C). They are functionally equivalent in all circuit applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly or lower-volume production. The physical component itself is identical.

Q: Can I use PCF2CT631R3R3K as a direct replacement for PCF2C3R3K?

A: Yes, for circuit functionality. The substitute part is electrically and mechanically identical. However, packaging format compatibility with your assembly process must be confirmed. If your assembly line requires Tape & Reel format, Cut Tape packaging will require process modification.

Q: Do both parts meet automotive standards?

A: Yes. Both PCF2C3R3K and PCF2CT631R3R3K carry AEC-Q200 qualification and are ROHS3 compliant, meeting automotive industry requirements.

Q: Which part should I select if both are available?

A: Selection depends on your assembly process and packaging requirements. For automated assembly with pick-and-place equipment, use the Tape & Reel format (PCF2C3R3K). For manual assembly or lower-volume applications, the Cut Tape format (PCF2CT631R3R3K) may be more practical. Both deliver identical electrical performance.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate identically across the -40°C to 200°C range and share identical temperature coefficient specifications. Environmental compliance (REACH Unaffected) is also identical.
