Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 41J2K2 is determined by strict equivalence across the following parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Termination count: 2

The identified substitute, 41J2K2E, maintains identical electrical and mechanical specifications while differing in packaging format (bulk versus standard) and RoHS compliance status. Both parts belong to the Ohmicone® 40 series and share active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between 41J2K2 and 41J2K2E depends on regulatory and compliance requirements:

The 41J2K2E is the appropriate selection for applications subject to RoHS3 compliance mandates, as it meets ROHS3 standards while maintaining identical electrical performance and mechanical compatibility. Both parts are REACH Unaffected and classified under ECCN EAR99.

The 41J2K2 remains suitable for applications without RoHS compliance requirements or for legacy system maintenance where non-compliant components are acceptable.

Both parts maintain active product status with adequate inventory availability, ensuring supply continuity for either selection.

Frequently Asked Questions (FAQ)

Q: Are 41J2K2 and 41J2K2E electrically interchangeable?

A: Yes. Both parts are identical in resistance value (2.2 kOhms), tolerance (±5%), power rating (1W), composition (wirewound), temperature coefficient (±20ppm/°C), and all other electrical parameters.

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

A: The primary differences are packaging format (41J2K2 uses standard packaging; 41J2K2E uses bulk packaging) and RoHS compliance status (41J2K2 is non-compliant; 41J2K2E is ROHS3 compliant).

Q: Can I use 41J2K2E as a direct replacement for 41J2K2 in my design?

A: Yes, provided your application accommodates bulk packaging format. The axial dimensions, termination configuration, and all electrical specifications are identical.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For RoHS3-regulated applications, use 41J2K2E. For applications without RoHS compliance mandates, either part is acceptable based on packaging and procurement preferences.

Q: Are there any mechanical compatibility concerns between these parts?

A: No. Both parts share identical physical dimensions (0.126" Dia x 0.437" L / 3.20mm x 11.10mm) and axial package configuration, ensuring mechanical interchangeability in PCB layouts and through-hole applications.

Q: What is the temperature coefficient significance for these parts?

A: The ±20ppm/°C temperature coefficient indicates the resistance value will change by approximately 20 parts per million for each degree Celsius change in operating temperature. This specification is identical for both parts.
