Substitute Part Grouping Explanation

Substitute parts for the 92J56R are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Resistance value: 56 Ohms
• Tolerance: ±5%
• Power rating: 2.25W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety characteristics

The 92J56RE meets all these criteria and is classified as a parametric equivalent. Differences exist only in packaging format (bulk versus standard) and compliance certifications, which do not affect electrical or mechanical performance in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 92J56R and 92J56RE are active production components from Ohmite's Series 90 wirewound resistor line. Selection between these parts should be based on the following factors:

92J56R is suitable for applications where standard packaging is preferred and RoHS non-compliance is acceptable for the end application.

92J56RE is the appropriate choice for applications requiring ROHS3 compliance or where bulk packaging format aligns with procurement and assembly workflows. The ROHS3 compliance and MSL rating of 1 (Unlimited) provide additional environmental and moisture handling flexibility.

Both parts are electrically and mechanically identical, with identical thermal characteristics and power dissipation capabilities. Selection does not impact circuit performance or reliability when used within specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 92J56RE be used as a direct replacement for the 92J56R?

A: Yes. The 92J56RE is a parametric equivalent with identical electrical specifications, power rating, physical dimensions, and thermal characteristics. The only differences are packaging format and RoHS compliance status.

Q: What is the difference between the standard and bulk packaging formats?

A: Packaging format refers to the quantity and presentation method for procurement. Both formats contain the same component with identical specifications. Selection depends on procurement volume requirements and assembly line handling preferences.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts deliver identical circuit performance.

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 are compatible with identical PCB layouts and through-hole mounting patterns.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component can be stored indefinitely without moisture-related degradation, providing maximum flexibility in inventory management and storage conditions.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Both parts are from the same manufacturer series with identical electrical and mechanical specifications, making them fully interchangeable for circuit design and assembly purposes.
