Substitute Part Grouping Explanation

Substitute parts for the Ohmite 43J1R5 are qualified based on strict equivalence of the following parameters:

• Resistance value: 1.5 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.220" Dia x 0.594" L (5.60mm x 15.10mm)
• Termination count: 2

The substitute part 43J1R5E maintains identical electrical and mechanical specifications, differing only in packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 43J1R5 and 43J1R5E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and packaging needs:

The 43J1R5E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulations. The 43J1R5 is RoHS non-compliant and appropriate for applications without RoHS requirements. Both parts maintain REACH Unaffected status and are classified under ECCN EAR99 and HTSUS 8533.21.0080.

Packaging format differs between the two parts: the 43J1R5 uses standard packaging while the 43J1R5E is supplied in bulk format. This distinction may influence procurement decisions based on volume requirements and handling procedures.

Frequently Asked Questions (FAQ)

Q: Are the 43J1R5 and 43J1R5E electrically identical?

A: Yes. Both parts have identical resistance (1.5 Ohms), tolerance (±5%), power rating (3W), temperature coefficient (±50ppm/°C), and wirewound composition. They are functionally equivalent in circuit applications.

Q: What is the primary difference between these two parts?

A: The main differences are RoHS compliance status and packaging format. The 43J1R5E is ROHS3 compliant and supplied in bulk packaging, while the 43J1R5 is RoHS non-compliant with standard packaging.

Q: Can I use 43J1R5E as a direct replacement for 43J1R5?

A: Yes, from an electrical and mechanical standpoint. However, verify that your application or regulatory environment permits the use of ROHS3 compliant components, as the 43J1R5 is RoHS non-compliant.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.220" Dia x 0.594" L (5.60mm x 15.10mm) and use identical axial through-hole packaging with 2 terminations.

Q: Which part should I select for new designs?

A: For new designs, the 43J1R5E is recommended due to ROHS3 compliance, which aligns with current regulatory standards. Select the 43J1R5 only if your application specifically requires a non-compliant component or if legacy design constraints mandate it.
