Key Parameters

Substitute Part Grouping Explanation

The Ohmite 40J2R2E is identified as a parametric equivalent to the 40J2R2. Substitution is valid based on the following criteria:

• Identical resistance value: 2.2 Ohms
• Identical tolerance: ±5%
• Identical power rating: 10W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±50ppm/°C
• Identical physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Identical number of terminations: 2
• Same series: Ohmicone® 40
• Same product status: Active

The primary distinction between these parts is packaging configuration and RoHS compliance status. The 40J2R2E is supplied in Bulk packaging and is ROHS3 compliant, whereas the 40J2R2 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J2R2 and 40J2R2E are Active status components suitable for direct substitution in applications where electrical and mechanical specifications are the primary selection criteria. The 40J2R2E offers ROHS3 compliance, making it the appropriate choice for applications subject to RoHS3 regulatory requirements. The 40J2R2E is available in higher inventory quantity (1137 units versus 694 units), providing greater availability for high-volume procurement. Selection between these parts should be based on compliance requirements and packaging preferences, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the 40J2R2E replace the 40J2R2 in all applications?

A: Yes. The 40J2R2E is electrically and mechanically identical to the 40J2R2. Both components have the same resistance value (2.2 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±50ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). Selection should be based on compliance requirements and packaging needs.

Q: What is the difference between the 40J2R2 and 40J2R2E?

A: The primary differences are packaging configuration and RoHS compliance status. The 40J2R2E is supplied in Bulk packaging and is ROHS3 compliant, while the 40J2R2 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 40J2R2 and 40J2R2E are manufactured by Ohmite and belong to the Ohmicone® 40 series.

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

A: The 40J2R2E is ROHS3 compliant and is the appropriate selection for applications subject to RoHS3 regulatory requirements.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts have identical dimensions of 0.406" Dia x 1.902" L (10.30mm x 48.30mm) and are supplied in axial package configuration with 2 terminations.
