Key Parameters

Substitute Part Grouping Explanation

The Ohmite 92J4R7E qualifies as a parametric equivalent substitute based on the following criteria:

Electrical Parameters Match:

• Resistance value: 4.7 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 2.25W (identical)
• Temperature coefficient: ±100ppm/°C (identical)

Mechanical Parameters Match:

• Package type: Axial (identical)
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm) (identical)
• Number of terminations: 2 (identical)

Composition & Features Match:

• Wirewound construction (identical)
• Flame retardant coating and safety features (identical)
• Series 90 (identical)

The primary difference is packaging format (Bulk vs. standard) and RoHS compliance status, which do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 92J4R7 and 92J4R7E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on:

Compliance Requirements: The 92J4R7E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 92J4R7 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging and Inventory: The 92J4R7E is available in bulk packaging with significantly higher inventory levels (4670 Pcs vs. 869 Pcs), making it preferable for high-volume production runs or when bulk procurement is advantageous.

Functional Interchangeability: Both parts are functionally identical in circuit applications. PCB layout, thermal management, and electrical performance will be equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 92J4R7E be used as a direct replacement for the 92J4R7 in existing designs?

A: Yes. The 92J4R7E is electrically and mechanically identical to the 92J4R7. Both parts have the same resistance value (4.7 Ohms), tolerance (±5%), power rating (2.25W), axial package dimensions, and wirewound construction. Direct substitution in PCB layouts and circuit designs is valid.

Q: What is the difference between the 92J4R7 and 92J4R7E?

A: The primary differences are packaging format (standard vs. bulk), RoHS compliance status (non-compliant vs. ROHS3 compliant), and inventory availability. Electrical and mechanical specifications are identical.

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

A: The 92J4R7E is ROHS3 compliant and must be used for applications requiring RoHS certification. The 92J4R7 is not RoHS compliant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.220" Dia x 0.406" L (5.60mm x 10.30mm) and use the same axial package type. They are mechanically interchangeable on PCBs.

Q: What is the temperature coefficient for these resistors?

A: Both parts have a temperature coefficient of ±100ppm/°C, indicating stable resistance performance across the operating temperature range.

Q: Can these parts be used in high-temperature applications?

A: The operating temperature range is not specified in the provided data. Consult the manufacturer's datasheet for specific temperature operating limits and thermal performance characteristics.
