Key Parameters

Substitute Part Grouping Explanation

The R5J3R0E is classified as a parametric equivalent to the R5J3R0. Substitution is valid based on the following criteria:

• Identical resistance value: 3 Ohms
• Identical tolerance: ±5%
• Identical power rating: 5W
• Identical composition: Wirewound
• Identical package type: Radial Lead
• Identical temperature coefficient: ±260ppm/°C
• Identical physical dimensions: 0.625" L x 0.344" W (15.88mm x 8.74mm)
• Identical height: 0.516" (13.11mm)
• Identical number of terminations: 2
• Identical series: PC-58
• Identical ECCN and HTSUS classifications

The primary distinction between these parts is compliance status and moisture sensitivity rating, which do not affect electrical or mechanical interchangeability in standard applications.

Engineering Selection Recommendations

Both R5J3R0 and R5J3R0E are electrically and mechanically identical 3 Ohm, 5W wirewound resistors from the Ohmite PC-58 series. Selection between these parts should be based on regulatory and compliance requirements:

• Select R5J3R0E for applications requiring ROHS3 compliance or REACH compliance verification
• Select R5J3R0 where RoHS non-compliant components are acceptable and inventory availability is prioritized
• Both parts are suitable for identical circuit applications due to matching electrical parameters, physical dimensions, and thermal characteristics
• Inventory levels should be considered for supply chain planning, with R5J3R0 currently offering higher stock availability

Frequently Asked Questions (FAQ)

Q: Can R5J3R0E be used as a direct replacement for R5J3R0?

A: Yes. The R5J3R0E is a direct parametric equivalent with identical resistance, tolerance, power rating, composition, package type, dimensions, and thermal characteristics. No circuit modifications are required.

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

A: The primary differences are RoHS compliance status and moisture sensitivity rating. R5J3R0E is ROHS3 compliant with MSL 1 (Unlimited), while R5J3R0 is RoHS non-compliant with MSL not applicable. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.625" L x 0.344" W (15.88mm x 8.74mm) and maximum seated height of 0.516" (13.11mm), ensuring identical PCB footprint compatibility.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For designs requiring RoHS3 compliance, select R5J3R0E. For applications without compliance mandates, either part is suitable based on availability and cost considerations.

Q: Are there any thermal or frequency limitations that differ between these parts?

A: No. Both parts share identical temperature coefficient (±260ppm/°C) and all other thermal specifications. No differences exist in frequency response or thermal performance.
