Substitute Part Grouping Explanation

Substitution of the Ohmite 27J33R is determined by matching the following critical electrical and mechanical parameters:

• Resistance Value: 33 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 7W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.394" Dia x 1.264" L (exact match required)
• Temperature Coefficient: ±30ppm/°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)

The substitute part 27J33RE meets all electrical and mechanical parameters of the main part. The primary difference is packaging configuration (Bulk versus standard packaging), which does not affect electrical performance or physical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 27J33R and 27J33RE are Active status components manufactured by Ohmite and are electrically and mechanically identical. The 27J33RE offers ROHS3 compliance, which may be required for applications subject to RoHS regulations. The 27J33R is classified as RoHS non-compliant. Selection between these parts should be based on regulatory compliance requirements for the end application. Both components carry identical ECCN and HTSUS classifications and are suitable for direct substitution in circuit designs where the specified electrical and mechanical parameters are required.

Frequently Asked Questions (FAQ)

Q: Can the 27J33RE be used as a direct replacement for the 27J33R?

A: Yes. The 27J33RE is electrically and mechanically identical to the 27J33R. All critical parameters including resistance value, tolerance, power rating, composition, package type, physical dimensions, and temperature coefficient are identical. The components are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between the 27J33R and 27J33RE?

A: The primary difference is RoHS compliance status. The 27J33RE is ROHS3 compliant, while the 27J33R is RoHS non-compliant. Packaging configuration also differs (standard versus Bulk). Electrical and mechanical specifications are identical.

Q: Does the packaging difference affect circuit performance?

A: No. Packaging configuration (standard versus Bulk) does not affect electrical performance, physical dimensions, or circuit compatibility. Both parts are supplied in Axial package type with identical physical dimensions of 0.394" Dia x 1.264" L.

Q: Which part should I select for RoHS-regulated applications?

A: The 27J33RE should be selected for applications requiring RoHS compliance. This part carries ROHS3 Compliant status, whereas the 27J33R is RoHS non-compliant.

Q: Are both parts currently available?

A: Both parts are classified as Active product status. Inventory availability should be confirmed with the supplier, as stock levels may vary.
