Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF1C274K are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match Exactly):

• Resistance value: 270 kOhms
• Tolerance: ±10%
• Power rating: 1W
• Temperature coefficient: -900/-2200ppm/°C
• Operating temperature range: -40°C ~ 200°C

Mechanical Parameters (Must Match Exactly):

• Composition: Ceramic
• Package case: Axial
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Number of terminations: 2

Compliance & Certification (Must Match):

• Automotive AEC-Q200 qualification
• Flame proof construction
• Non-inductive design
• Pulse withstanding capability
• ROHS3 compliance

Packaging Format (May Differ): The primary distinction between the main part and its substitute relates to packaging format. The PCF1C274K is supplied in Tape & Reel (TR) format, while equivalent parts may be available in Cut Tape (CT) format. Both packaging formats contain identical components with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PCF1CT631R274K is a direct functional equivalent to the PCF1C274K. Both parts are manufactured by KOA Speer Electronics, Inc., maintain active production status, and carry identical electrical specifications, mechanical dimensions, and automotive certifications.

The sole difference between these parts is the packaging format: PCF1C274K is supplied in Tape & Reel (TR) format, while PCF1CT631R274K is supplied in Cut Tape (CT) format. This distinction affects procurement and handling procedures but does not impact component performance, reliability, or circuit functionality.

Selection between these parts should be based on:

1. Packaging Requirements: Choose Tape & Reel format for high-volume automated assembly operations. Choose Cut Tape format for lower-volume applications or when tape-based handling equipment is unavailable.

2. Supply Availability: PCF1CT631R274K currently has higher inventory availability (1661 pieces) compared to PCF1C274K (879 pieces).

3. Compliance Continuity: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and automotive AEC-Q200 qualification, ensuring regulatory requirements are met regardless of which part is selected.

4. Cost Considerations: Packaging format may influence unit pricing and minimum order quantities. Procurement should evaluate total cost of ownership including packaging, handling, and logistics.

Frequently Asked Questions (FAQ)

Q: Can PCF1CT631R274K be used as a direct replacement for PCF1C274K in automotive applications?

A: Yes. Both parts are identical in electrical performance, mechanical dimensions, and automotive qualification. The only difference is packaging format (Cut Tape versus Tape & Reel). The component itself is functionally equivalent.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on tape segments, typically used for lower-volume applications or manual assembly. The resistor component itself is identical in both formats.

Q: Do both parts meet the same automotive standards?

A: Yes. Both PCF1C274K and PCF1CT631R274K carry AEC-Q200 automotive qualification, flame-proof construction, non-inductive design, and pulse-withstanding capability. Both are ROHS3 compliant and REACH unaffected.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.217" diameter by 0.650" length (5.50mm x 16.50mm). They are mechanically interchangeable in circuit board layouts and through-hole designs.

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

A: Both parts operate across the identical temperature range of -40°C to 200°C with a temperature coefficient of -900/-2200ppm/°C.

Q: Can I mix packaging formats in the same production run?

A: Yes, from a component performance perspective. However, mixing packaging formats may require different handling procedures and assembly equipment configurations. Procurement and manufacturing should coordinate to optimize assembly efficiency.

Q: Which part should I specify for new designs?

A: Either part is acceptable for new designs. Selection should be based on your manufacturing capabilities, assembly equipment, and supply chain preferences. Both parts are active production items with equivalent long-term availability.
