Substitute Part Grouping Explanation

Substitution of the CFS1/2C473J is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CFS1/2CT52R473J qualifies as a parametric equivalent based on identical specifications in the following categories:

Electrical Parameters: Resistance value (47 kOhms), tolerance band (±5%), power dissipation rating (0.5W), temperature coefficient (-450/+350 ppm/°C), and operating temperature range (-55°C to 155°C) are identical.

Mechanical Parameters: Package configuration (Axial), physical dimensions (0.112" Dia × 0.248" L), number of terminations (2), and composition (Carbon Film) are identical.

Compliance & Regulatory: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications.

Series Designation: Both parts belong to the KOA Speer CF series base product family.

Substitution is valid only when all parameters listed above remain unchanged in the circuit application.

Parameter Comparison

Engineering Selection Recommendations

Both the CFS1/2C473J and CFS1/2CT52R473J are Active products with full regulatory compliance. Selection between these parts is based on inventory availability and supply chain requirements rather than functional differences.

The CFS1/2CT52R473J offers significantly higher inventory availability (8723 pieces in stock versus 992 pieces for the CFS1/2C473J), making it the preferred selection for high-volume production runs or applications requiring extended supply assurance.

Both parts maintain identical electrical performance, mechanical compatibility, and compliance certifications. PCB layout, footprint requirements, and thermal management considerations remain unchanged between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can CFS1/2CT52R473J be used as a direct replacement for CFS1/2C473J?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and compliance specifications. Direct substitution is valid without circuit redesign or re-qualification.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts share identical axial package dimensions of 0.112" diameter by 0.248" length (2.85mm × 6.30mm). PCB footprint and mounting requirements are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CFS1/2C473J and CFS1/2CT52R473J are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.10.0065) classifications.

Q: What is the difference between these two part numbers?

A: The part numbers reflect different manufacturing batches or tape reel configurations within the same product specification. All functional and physical parameters remain identical.

Q: Are temperature coefficient and operating temperature range the same?

A: Yes. Both parts operate across -55°C to 155°C with identical temperature coefficient of -450/+350 ppm/°C.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. No design changes, re-layout, or re-testing are required when substituting between these part numbers in active designs.
