Substitute Part Grouping Explanation

The 90J910E is classified as a parametric equivalent to the 90J910. Substitution eligibility is determined by the following critical parameters:

• Resistance Value: 910 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 11W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.343" Dia x 1.811" L (exact match required)
• Temperature Coefficient: ±30ppm/°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)

The 90J910E differs from the 90J910 in packaging format (Bulk versus standard) and RoHS compliance status. Both parts are manufactured by Ohmite and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 90J910 and 90J910E are electrically and mechanically identical components. Selection between these parts is determined by compliance and packaging requirements:

90J910: Select this part number for applications where RoHS non-compliant components are acceptable and standard packaging is required.

90J910E: Select this part number for applications requiring ROHS3 compliance or when bulk packaging is specified. This variant maintains all electrical and thermal characteristics of the 90J910 while meeting enhanced environmental compliance standards.

Both parts are active products with current inventory availability. The choice between them does not affect circuit performance, thermal behavior, or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 90J910E be used as a direct replacement for the 90J910?

A: Yes. The 90J910E is a direct parametric equivalent. All electrical specifications, power rating, resistance value, tolerance, temperature coefficient, and physical dimensions are identical. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the standard packaging and bulk packaging?

A: Packaging format refers to the quantity and presentation method for component delivery. Standard packaging and bulk packaging contain identical components; the difference is in order quantity and container type. Electrical and mechanical performance is unaffected by packaging format.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both the 90J910 and 90J910E deliver identical electrical characteristics and thermal performance.

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

A: Yes. Both the 90J910 and 90J910E measure 0.343" diameter by 1.811" length (8.70mm x 46.00mm). They are mechanically interchangeable in all PCB layouts and mechanical assemblies.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±30ppm/°C, indicating the resistance change per degree Celsius across the operating temperature range. This specification is identical for both part numbers.

Q: Can these parts be used in safety-critical applications?

A: Yes. Both the 90J910 and 90J910E feature flame retardant coating and safety-rated construction, making them suitable for safety-critical applications where these certifications are required.
