Substitute Part Grouping Explanation

Substitute parts for the Ohmite 91J2K2 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for substitution eligibility:

• Resistance Value: 2.2 kOhms
• Tolerance: ±5%
• Power Rating: 1.5W
• Composition: Wirewound
• Package Type: Axial
• Size / Dimension: 0.142" Dia x 0.453" L (3.60mm x 11.50mm)
• Temperature Coefficient: ±30ppm/°C
• Features: Flame Retardant Coating, Safety
• Number of Terminations: 2

The Ohmite 91J2K2E meets all these criteria and is classified as a parametric equivalent. Packaging differences (Bulk vs. standard packaging) do not affect electrical or mechanical compatibility and represent procurement variants of the same component specification.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 91J2K2 and 91J2K2E are Active status components with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and application constraints:

The 91J2K2E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 91J2K2 is RoHS non-compliant and should be selected only for applications where RoHS compliance is not required.

Both components are suitable for through-hole PCB assembly in axial orientation. Inventory availability is comparable, with 91J2K2E showing slightly higher stock levels (1135 pcs vs. 1087 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 91J2K2E be used as a direct replacement for the 91J2K2?

A: Yes. The 91J2K2E is a parametric equivalent with identical resistance value (2.2 kOhms), tolerance (±5%), power rating (1.5W), composition (wirewound), package type (axial), physical dimensions (0.142" Dia x 0.453" L), temperature coefficient (±30ppm/°C), and safety features. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the 91J2K2 and 91J2K2E?

A: The primary differences are packaging format (standard vs. Bulk) and compliance certifications. The 91J2K2E is ROHS3 compliant with MSL rating of 1 (Unlimited), while the 91J2K2 is RoHS non-compliant with MSL listed as Not Applicable. All electrical and mechanical parameters are identical.

Q: Are there any PCB layout or assembly considerations when substituting these parts?

A: No. Both parts use identical axial package geometry (0.142" Dia x 0.453" L) and two-terminal configuration. PCB footprints, lead spacing, and assembly processes remain unchanged.

Q: Which part should be selected for RoHS-regulated applications?

A: The 91J2K2E is ROHS3 compliant and must be used for applications subject to RoHS directives. The 91J2K2 is not RoHS compliant and is restricted to non-regulated applications.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 91J2K2 and 91J2K2E are manufactured by Ohmite and belong to the Series 90 product line.
