Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 43J800 are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Resistance value: 800 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)
• Termination count: 2

The substitute part 43J800E maintains all critical electrical specifications and mechanical form factor, differing only in packaging configuration (Bulk versus standard packaging) and RoHS compliance status. This substitution is valid for applications where these parameters are the determining factors for component selection.

Parameter Comparison

Engineering Selection Recommendations

Both the 43J800 and 43J800E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging needs:

The 43J800E offers ROHS3 compliance, making it suitable for applications subject to RoHS directives and regulations requiring lead-free construction. The 43J800 remains available for applications where RoHS compliance is not a requirement. Both parts are REACH Unaffected and classified under ECCN EAR99, with matching HTSUS codes (8533.21.0080). Packaging configuration differs between standard and bulk options; bulk packaging (43J800E) may be preferred for high-volume procurement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 43J800E directly replace the 43J800 in existing designs?

A: Yes. The 43J800E is electrically and mechanically equivalent to the 43J800. All critical parameters—resistance, tolerance, power rating, temperature coefficient, and physical dimensions—are identical. The substitute is suitable for direct replacement in circuit applications.

Q: What is the difference between the 43J800 and 43J800E?

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. The 43J800E is ROHS3 compliant, while the 43J800 is RoHS non-compliant. All electrical and mechanical specifications remain unchanged.

Q: Should I select the 43J800E for new designs?

A: Selection depends on regulatory and compliance requirements applicable to your application. If RoHS compliance is mandated, the 43J800E is the appropriate choice. Both parts are active in production and available in inventory.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical temperature coefficient (±20ppm/°C), power rating (3W), and all other electrical specifications. Performance in thermal and electrical operation is equivalent.

Q: What packaging options are available?

A: The 43J800 is supplied in standard packaging, while the 43J800E is available in bulk packaging. Bulk packaging is typically used for high-volume orders and may offer cost advantages for large-quantity procurement.
