Substitute Part Grouping Explanation

The CW0103K300JE73 qualifies as a parametric equivalent to the CW0103K300JS67 based on the following criteria:

All electrical parameters are identical: 3.3 kOhms resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating temperature range.

All mechanical parameters are identical: axial package type, 0.375" diameter by 1.781" length (9.52mm x 45.24mm), two terminations, and moisture-resistant wirewound composition.

The only difference is packaging format: CW0103K300JS67 is supplied in Tape & Reel (TR) configuration, while CW0103K300JE73 is supplied in Cut Tape (CT) configuration. Both are standard distribution formats for the same component.

Engineering Selection Recommendations

Both CW0103K300JS67 and CW0103K300JE73 are active production parts with identical electrical and mechanical specifications. Selection between them depends on procurement and assembly requirements:

The CW0103K300JS67 in Tape & Reel format is suitable for automated pick-and-place assembly operations. The CW0103K300JE73 in Cut Tape format is suitable for manual assembly or lower-volume applications.

The CW0103K300JE73 offers improved regulatory compliance with ROHS3 certification and REACH unaffected status, compared to the CW0103K300JS67 which is RoHS non-compliant and REACH affected. Applications subject to environmental or regulatory restrictions should prioritize the CW0103K300JE73.

Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Can CW0103K300JE73 be used as a direct replacement for CW0103K300JS67?

A: Yes. Both parts have identical electrical specifications (3.3 kOhms, ±5%, 13W), identical mechanical dimensions (0.375" Dia x 1.781" L), and identical thermal characteristics (±30ppm/°C, -65°C to 350°C). The only difference is packaging format: Tape & Reel versus Cut Tape. Electrical and thermal performance are equivalent.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for automated assembly equipment. Cut Tape (CT) packaging supplies the same components on shorter tape segments, suitable for manual assembly or lower-volume production. Both formats contain identical components.

Q: Does the packaging format affect component performance?

A: No. Packaging format affects only handling, storage, and assembly method. The resistor itself—its resistance value, power rating, temperature coefficient, and operating range—remains identical regardless of whether it arrives in Tape & Reel or Cut Tape format.

Q: Why does CW0103K300JE73 have better RoHS and REACH compliance?

A: Compliance status reflects manufacturing process and material composition at the time of production. CW0103K300JE73 meets ROHS3 standards and is REACH unaffected, indicating it was manufactured under more recent environmental regulations. CW0103K300JS67 predates these requirements. Both parts function identically in circuit applications.

Q: Which part should I select for new designs?

A: For new designs, CW0103K300JE73 is the preferred choice due to active production status and improved regulatory compliance (ROHS3, REACH unaffected). Both parts are currently active, but CW0103K300JE73 offers better long-term availability and regulatory alignment.

Q: Are there inventory differences between these parts?

A: Yes. CW0103K300JS67 has 844 units in stock, while CW0103K300JE73 has 2021 units available. Higher inventory of the substitute part supports consistent supply for production requirements.
