Substitute Part Grouping Explanation

Substitution for the CW02B4K700JS70 is determined by electrical equivalence and mechanical compatibility. The primary substitute, CW02B4K700JE70, maintains identical electrical characteristics: 4.7 kOhms resistance, ±5% tolerance, 3.75W power rating, wirewound composition, and axial package configuration. Both parts share the same physical dimensions (0.188" Dia x 0.562" L), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C).

The key differentiator between these parts is packaging format. The main part (CW02B4K700JS70) is supplied in Tape & Reel (TR) format, while the substitute (CW02B4K700JE70) is supplied in Cut Tape (CT) format. This distinction affects procurement and assembly processes but does not alter component performance or compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B4K700JS70 and CW02B4K700JE70 are electrically and mechanically equivalent and suitable for identical circuit applications. Selection between these parts depends on procurement and assembly requirements rather than performance characteristics.

The CW02B4K700JS70 (Tape & Reel format) is appropriate for high-volume automated assembly operations where tape-fed component handling is standard. The CW02B4K700JE70 (Cut Tape format) is suitable for lower-volume applications, manual assembly, or situations where individual component handling is preferred.

Compliance considerations differ between the two parts. The CW02B4K700JE70 offers ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to these regulatory requirements. The CW02B4K700JS70 is RoHS non-compliant and REACH affected, limiting its use in regulated markets.

Frequently Asked Questions (FAQ)

Q: Are CW02B4K700JS70 and CW02B4K700JE70 electrically identical?

A: Yes. Both parts have identical resistance (4.7 kOhms), tolerance (±5%), power rating (3.75W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°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 continuous tape wound on a reel, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual handling or lower-volume assembly processes. Both formats contain the same component.

Q: Can I use CW02B4K700JE70 as a direct replacement for CW02B4K700JS70?

A: Yes, for circuit functionality. Both parts are mechanically and electrically identical. However, assembly process compatibility depends on your equipment. Automated systems designed for Tape & Reel format may require adjustment for Cut Tape format.

Q: Which part should I select for RoHS-compliant applications?

A: The CW02B4K700JE70 is ROHS3 compliant and REACH unaffected, making it suitable for regulated markets. The CW02B4K700JS70 is RoHS non-compliant and REACH affected.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts measure 0.188" Dia x 0.562" L (4.78mm x 14.27mm) and are housed in identical axial packages. They are mechanically interchangeable in PCB layouts and mechanical assemblies.
