Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 95J2K2E are qualified based on the following criteria:

• Identical resistance value: 2.2 kOhms
• Matching tolerance: ±5%
• Equivalent power rating: 5W
• Same composition type: Wirewound
• Identical package configuration: Axial through-hole
• Matching temperature coefficient: ±30ppm/°C
• Equivalent safety and flame retardant features
• RoHS compliance maintained
• MSL rating of 1 or better

The 25J2K2E meets all substitution criteria and is qualified as a direct equivalent for the 95J2K2E.

Parameter Comparison

Engineering Selection Recommendations

Both the 95J2K2E and 25J2K2E are Active product status components manufactured by Ohmite with full RoHS compliance and MSL 1 rating. The electrical specifications are identical across all critical parameters: resistance, tolerance, power rating, temperature coefficient, and composition. Both components feature flame retardant coating and safety characteristics.

The primary differences are series designation (90 versus 20), packaging format (Box versus Bulk), and physical dimensions. The 25J2K2E exhibits slightly larger physical dimensions (0.276" diameter versus 0.264", and 1.016" length versus 0.969"). These dimensional variations remain within acceptable tolerances for standard axial through-hole mounting applications and do not affect electrical performance or thermal characteristics.

Selection between these parts should be based on packaging availability, inventory requirements, and physical space constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 25J2K2E be used as a direct replacement for the 95J2K2E?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, temperature coefficient, and safety features. The primary consideration is the slight dimensional difference, which is acceptable for standard PCB layouts.

Q: What is the significance of the Series designation difference (90 versus 20)?

A: The Series designation indicates the product line within Ohmite's wirewound resistor portfolio. Both Series 90 and Series 20 meet the same electrical and safety specifications for this 2.2 kOhms 5W axial resistor configuration.

Q: Are there packaging considerations when substituting between these parts?

A: Yes. The 95J2K2E is supplied in Box packaging, while the 25J2K2E is supplied in Bulk packaging. Verify that your procurement and inventory management processes accommodate the packaging format of your selected substitute.

Q: Do the physical dimension differences affect circuit board design?

A: The 25J2K2E is slightly larger (0.276" diameter and 1.016" length) compared to the 95J2K2E (0.264" diameter and 0.969" length). For standard through-hole applications with typical component spacing, these differences are negligible. Verify clearance in space-constrained layouts.

Q: Are both parts RoHS compliant?

A: Yes. Both the 95J2K2E and 25J2K2E are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
