Key Parameters

Substitute Part Grouping Explanation

Substitution of the Ohmite 90J2K2 is based on strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (2.2 kOhms), tolerance (±5%), and power rating (11W) must be identical
• Physical Form Factor: Axial package configuration with matching dimensions (0.343" Dia x 1.811" L)
• Composition & Features: Wirewound construction with flame retardant coating and safety features
• Temperature Performance: Temperature coefficient of ±30ppm/°C
• Termination Count: Two-terminal configuration

The identified substitute part maintains all electrical and mechanical parameters while differing only in packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J2K2 and 90J2K2E are active production components from Ohmite's Series 90 resistor line. Selection between these parts should be based on the following criteria:

90J2K2: Select this part number when standard packaging is required and RoHS non-compliant components are acceptable for the application.

90J2K2E: Select this part number when ROHS3 compliance is mandated by design requirements or regulatory standards. This variant is supplied in bulk packaging format and offers unlimited moisture sensitivity rating.

Both parts are electrically and mechanically identical, ensuring direct substitution without circuit redesign or performance impact.

Frequently Asked Questions (FAQ)

Q: Can 90J2K2E be used as a direct replacement for 90J2K2?

A: Yes. The 90J2K2E is a direct electrical and mechanical equivalent. All critical parameters including resistance, tolerance, power rating, temperature coefficient, and physical dimensions are identical. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the packaging formats?

A: The 90J2K2 is supplied in standard packaging, while the 90J2K2E is supplied in bulk packaging. Both contain the same component with identical electrical and mechanical specifications.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter the electrical performance or reliability of the component. Selection should be based on application regulatory requirements.

Q: Are the physical dimensions identical between both part numbers?

A: Yes. Both parts measure 0.343" Dia x 1.811" L (8.70mm x 46.00mm) and use identical axial package configuration, ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the moisture sensitivity rating difference?

A: The 90J2K2 has no applicable moisture sensitivity rating, while the 90J2K2E is rated MSL 1 (Unlimited). This indicates the 90J2K2E can be stored indefinitely without moisture control measures.
