Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 43J2R0 are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is parametric matching across resistance value, tolerance, power rating, composition type, and physical dimensions. The Ohmite 43J2R0E qualifies as a parametric equivalent because it maintains identical electrical specifications (2 Ohms ±5%, 3W wirewound) and mechanical form factor (0.220" Dia x 0.594" L axial package). The key differentiator is packaging configuration: the 43J2R0E is supplied in Bulk packaging, whereas the 43J2R0 uses standard packaging. Both parts belong to the Ohmicone® 40 series and share Active product status.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 43J2R0E serves as a direct parametric equivalent to the 43J2R0 for applications requiring identical electrical and mechanical performance. Selection between these parts depends on specific project requirements:

The 43J2R0 is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. Current inventory of 1141 pieces supports immediate availability.

The 43J2R0E is the appropriate choice for designs requiring ROHS3 compliance. With 970 pieces in stock, this substitute provides regulatory alignment while maintaining full electrical and mechanical compatibility. Both parts share identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 43J2R0E replace the 43J2R0 in existing designs?

A: Yes. The 43J2R0E is a parametric equivalent with identical resistance (2 Ohms), tolerance (±5%), power rating (3W), composition (wirewound), and physical dimensions (0.220" Dia x 0.594" L). Both are axial through-hole components with 2 terminations. The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between standard and Bulk packaging?

A: Packaging format affects order quantity and handling. Standard packaging is the default configuration for the 43J2R0. Bulk packaging for the 43J2R0E accommodates larger quantity orders. Both deliver identical component specifications and performance characteristics.

Q: Are there compliance differences between these parts?

A: Yes. The 43J2R0 is RoHS non-compliant, while the 43J2R0E is ROHS3 compliant. Both maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS (8533.21.0080) classifications. Select the 43J2R0E for applications requiring RoHS3 certification.

Q: Do these parts have identical temperature performance?

A: Yes. Both the 43J2R0 and 43J2R0E specify a temperature coefficient of ±50ppm/°C, ensuring equivalent thermal stability across the operating range.

Q: Are both parts currently available?

A: Yes. The 43J2R0 has 1141 pieces in stock, and the 43J2R0E has 970 pieces in stock. Both are classified as Active product status.
