Substitute Part Grouping Explanation

Substitute parts for the 93J2K7 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance value: 2.7 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3.25W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Physical dimensions: 0.233" Dia x 0.579" L (exact match required)
• Features: Flame retardant coating and safety rating (exact match required)

The 93J2K7E meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 93J2K7 and 93J2K7E are Active product status components from Ohmite's Series 90 resistor line. The primary distinction between these parts is regulatory compliance: the 93J2K7E is ROHS3 compliant, while the 93J2K7 is RoHS non-compliant. For applications subject to RoHS3 regulatory requirements, the 93J2K7E is the appropriate selection. Both parts are electrically and mechanically identical across all specified parameters, including resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The choice between these parts should be determined by compliance requirements applicable to the end application and regional regulations.

Frequently Asked Questions (FAQ)

Q: Can the 93J2K7E be used as a direct replacement for the 93J2K7?

A: Yes. The 93J2K7E is electrically and mechanically equivalent to the 93J2K7 across all specified parameters: 2.7 kOhms resistance, ±5% tolerance, 3.25W power rating, wirewound composition, axial package, ±30ppm/°C temperature coefficient, and identical physical dimensions. Direct substitution is permissible from an electrical and mechanical standpoint.

Q: What is the difference between the 93J2K7 and 93J2K7E?

A: The primary differences are regulatory compliance and packaging. The 93J2K7E is ROHS3 compliant with MSL rating of 1 (Unlimited), while the 93J2K7 is RoHS non-compliant with MSL listed as Not Applicable. All electrical and mechanical specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, specify the 93J2K7E. If RoHS compliance is not a constraint, either part meets the electrical and mechanical requirements. Verify compliance obligations for your specific application and region.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 93J2K7 and 93J2K7E have identical dimensions of 0.233" Dia x 0.579" L (5.90mm x 14.70mm) and are packaged as axial through-hole components with 2 terminations.

Q: What does the "E" designation in 93J2K7E indicate?

A: The "E" suffix indicates a variant within the Ohmite Series 90 resistor line. In this case, the 93J2K7E represents the ROHS3 compliant version of the base 93J2K7 part number.
