Substitute Part Grouping Explanation

Substitute parts for the 90J2K7 are identified based on strict parametric equivalence within Ohmite's product portfolio. The substitution criteria are:

• Resistance value: 2.7 kOhms
• Tolerance: ±5%
• Power rating: 11W
• Composition: Wirewound
• Package type: Axial through-hole configuration
• Electrical performance: Temperature coefficient and thermal characteristics suitable for equivalent applications

The 90J2K7E qualifies as a parametric equivalent based on matching resistance, tolerance, power rating, and through-hole axial construction. Both parts are manufactured by Ohmite and maintain the same electrical specifications required for direct functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the 90J2K7 and 90J2K7E maintain active product status from Ohmite and share identical electrical and mechanical specifications. Selection between these parts should be based on:

• Packaging format availability: 90J2K7 is supplied in standard packaging; 90J2K7E is available in bulk packaging
• Inventory requirements: 90J2K7 has 1040 units in stock; 90J2K7E has 842 units in stock
• Regulatory compliance: Both parts carry identical RoHS non-compliant and EAR99 classifications
• Supply chain considerations: Either part satisfies the same circuit requirements without performance differentiation

Frequently Asked Questions (FAQ)

Q: Can the 90J2K7E directly replace the 90J2K7 in existing designs?

A: Yes. Both parts are Ohmite wirewound axial resistors with identical electrical specifications: 2.7kΩ resistance, ±5% tolerance, 11W power rating, and ±30ppm/°C temperature coefficient. The primary difference is packaging format (standard vs. bulk).

Q: What are the critical parameters for substitution compatibility?

A: Resistance value (2.7kΩ), tolerance (±5%), power rating (11W), and axial through-hole package type must remain constant. Temperature coefficient and thermal performance characteristics are equivalent between the two parts.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS code (8533.21.0080). REACH status for the 90J2K7E is available upon request from the supplier.

Q: What is the physical dimension compatibility?

A: The 90J2K7 specifies dimensions of 0.343" diameter by 1.811" length (8.70mm x 46.00mm). The 90J2K7E maintains axial through-hole construction compatible with standard PCB layouts designed for this form factor.

Q: How should packaging format affect component selection?

A: The 90J2K7 is supplied in standard packaging suitable for individual component handling and kitting operations. The 90J2K7E is available in bulk packaging, appropriate for high-volume manufacturing or automated assembly processes. Electrical performance is identical; selection depends on procurement and assembly workflow requirements.
