Key Parameters

Substitute Part Grouping Explanation

The 92J1R2E qualifies as a parametric equivalent substitute based on the following criteria:

• Identical resistance value: 1.2 Ohms
• Identical tolerance: ±5%
• Identical power rating: 2.25W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Identical temperature coefficient: ±100ppm/°C
• Identical features: Flame Retardant Coating, Safety
• Identical number of terminations: 2
• Same manufacturer: Ohmite
• Same series: 90

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

Parameter Comparison

Engineering Selection Recommendations

Both the 92J1R2 and 92J1R2E are active production components from Ohmite's Series 90 wirewound resistor line. Selection between these parts should be based on regulatory and compliance requirements:

• 92J1R2: Select when RoHS non-compliant components are acceptable or required by design specifications.
• 92J1R2E: Select when ROHS3 compliance is mandated by end-use application or supply chain requirements.

Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. Inventory availability is comparable between both options.

Frequently Asked Questions (FAQ)

Q: Can 92J1R2E be used as a direct replacement for 92J1R2?

A: Yes. The 92J1R2E is electrically and mechanically identical to the 92J1R2. All critical parameters—resistance, tolerance, power rating, composition, package type, and physical dimensions—are identical. The primary difference is RoHS compliance status.

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

A: The 92J1R2 is RoHS non-compliant, while the 92J1R2E is ROHS3 compliant. Packaging configuration differs (standard vs. Bulk), but this does not affect circuit performance or PCB assembly compatibility.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.220" Dia x 0.406" L (5.60mm x 10.30mm) and use identical axial through-hole terminations. PCB footprints and mounting requirements are identical.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter the electrical specifications, tolerance, power rating, or temperature coefficient of the resistor.

Q: Which part should I specify for new designs?

A: Specify based on your application's regulatory requirements. If ROHS3 compliance is required, use 92J1R2E. If RoHS compliance is not a constraint, either part is suitable based on availability and cost considerations.
