Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NKN2WSJR-73-0R2 is determined by strict equivalence in the following critical parameters: resistance value (200 mOhms), tolerance (±5%), power rating (2W), composition (wirewound), package type (axial), operating temperature range (-40°C ~ 200°C), and compliance certifications (ROHS3, REACH Unaffected). All identified substitutes maintain these core electrical and mechanical specifications. Packaging format differences (Tape & Reel versus Cut Tape) do not affect functional compatibility but may influence procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All three parts—NKN2WSJR-73-0R2, NKN2WSJT-73-0R2, and NKN200JT-73-0R2—are electrically and mechanically equivalent for applications requiring 200 mOhms ±5% 2W axial wirewound resistors. Selection between these parts should be based on packaging format requirements and inventory availability. The NKN2WSJR-73-0R2 is supplied in Tape & Reel format, suitable for automated assembly processes. The NKN2WSJT-73-0R2 and NKN200JT-73-0R2 are supplied in Cut Tape format, appropriate for manual or semi-automated assembly workflows. All parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and consumer applications. The NKN200JT-73-0R2 offers the highest inventory availability at 4789 units.

Frequently Asked Questions (FAQ)

Q: Can NKN2WSJT-73-0R2 and NKN200JT-73-0R2 be used interchangeably with NKN2WSJR-73-0R2?

A: Yes. All three parts share identical electrical specifications (200 mOhms, ±5% tolerance, 2W power rating) and mechanical compatibility (axial package, same operating temperature range). The primary difference is packaging format: Tape & Reel versus Cut Tape. This affects procurement and assembly handling but not functional performance.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape packaging supplies the same components on shorter tape segments, suitable for lower-volume or manual assembly operations. Both formats contain identical components.

Q: Are there dimensional differences between these substitute parts?

A: The NKN2WSJR-73-0R2 and NKN2WSJT-73-0R2 share identical dimensions (0.189" Dia x 0.453" L / 4.80mm x 11.50mm). The NKN200JT-73-0R2 has slightly larger dimensions (0.209" Dia x 0.610" L / 5.30mm x 15.50mm) due to different internal construction, but both are functionally equivalent for the specified resistance, tolerance, and power rating.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry identical certifications (EAR99, HTSUS 8533.21.0080). They are suitable for applications with equivalent regulatory requirements.

Q: Which part should I select for maximum inventory availability?

A: The NKN200JT-73-0R2 offers the highest current stock level at 4789 units, compared to 1150 units for NKN2WSJT-73-0R2 and 1098 units for NKN2WSJR-73-0R2.
