Key Parameters

Substitute Part Grouping Explanation

The 90J1R8E qualifies as a parametric equivalent based on the following criteria:

• Identical resistance value: 1.8 Ohms
• Identical tolerance: ±5%
• Identical power rating: 11W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical physical dimensions: 0.343" Dia x 1.811" L (8.70mm x 46.00mm)
• Identical temperature coefficient: ±100ppm/°C
• Identical features: Flame Retardant Coating, Safety
• Identical number of terminations: 2

The primary difference between these parts is packaging format (Bulk for 90J1R8E versus standard for 90J1R8) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 90J1R8E serves as a direct parametric substitute for the 90J1R8 when electrical and mechanical specifications are the primary selection criteria. Selection between these parts should be based on:

• RoHS compliance requirements: The 90J1R8E is ROHS3 compliant, while the 90J1R8 is non-compliant. Applications subject to RoHS regulations require the 90J1R8E.
• Packaging format: The 90J1R8E is supplied in Bulk packaging, while the 90J1R8 uses standard packaging. Bulk packaging may be preferred for high-volume manufacturing operations.
• Inventory availability: Both parts maintain adequate stock levels (942 and 961 units respectively).

Both parts are classified as Active product status and share identical electrical performance characteristics, physical dimensions, and thermal properties.

Frequently Asked Questions (FAQ)

Q: Can the 90J1R8E replace the 90J1R8 in existing designs?

A: Yes. The 90J1R8E is electrically and mechanically equivalent to the 90J1R8. Both components have identical resistance values (1.8 Ohms), tolerance (±5%), power rating (11W), physical dimensions (0.343" Dia x 1.811" L), and thermal characteristics (±100ppm/°C). The axial package type and two-termination configuration are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Bulk for 90J1R8E versus standard for 90J1R8) and RoHS compliance status (ROHS3 Compliant for 90J1R8E versus non-compliant for 90J1R8). All electrical and mechanical specifications are identical.

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

A: The 90J1R8E is ROHS3 compliant and must be used for applications subject to RoHS regulations. The 90J1R8 is not RoHS compliant.

Q: Are the physical dimensions identical?

A: Yes. Both the 90J1R8 and 90J1R8E have identical dimensions of 0.343" Dia x 1.811" L (8.70mm x 46.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What packaging formats are available?

A: The 90J1R8 is supplied in standard packaging, while the 90J1R8E is supplied in Bulk packaging. Bulk packaging is typically used for high-volume manufacturing operations.
