Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF2CT631R100K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Temperature coefficient: -600 / -1500 ppm/°C
• Operating temperature range: -40°C ~ 200°C

Mechanical Parameters:

• Package type: Axial
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Number of terminations: 2

Compliance & Certification:

• Series: PCF
• Automotive qualification: AEC-Q200
• RoHS status: ROHS3 Compliant
• REACH status: REACH Unaffected

The substitute part PCF2C100K maintains identical electrical and mechanical specifications. The only difference is the packaging format: the main part is supplied in Cut Tape (CT) format, while the substitute is supplied in Tape & Reel (TR) format. Both parts are from the same PCF series and share all functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both PCF2CT631R100K and PCF2C100K are active production components from KOA Speer Electronics, Inc. with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is determined by procurement and assembly requirements rather than electrical or mechanical performance differences.

PCF2CT631R100K (Cut Tape packaging) is suitable for applications requiring smaller order quantities or manual component handling during assembly.

PCF2C100K (Tape & Reel packaging) is suitable for high-volume automated assembly operations where tape-and-reel format provides efficiency in pick-and-place equipment integration.

Both parts deliver identical circuit performance, reliability, and compliance certifications for automotive applications operating within the -40°C to 200°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can PCF2C100K replace PCF2CT631R100K in circuit design?

A: Yes. Both parts are electrically and mechanically identical with 10 Ohms resistance, ±10% tolerance, 2W power rating, and identical physical dimensions. The only difference is the packaging format (Cut Tape versus Tape & Reel).

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

A: Cut Tape (CT) format provides individual component strips suitable for manual handling and smaller quantities. Tape & Reel (TR) format supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both formats contain the same component.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both PCF2CT631R100K and PCF2C100K carry full AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your assembly process accommodates the packaging format. If your production line uses automated pick-and-place equipment, Tape & Reel format is recommended. For manual assembly or prototyping, Cut Tape format may be more practical.

Q: What is the operating temperature range for both parts?

A: Both parts operate reliably from -40°C to 200°C, with a temperature coefficient of -600 / -1500 ppm/°C.
