Substitute Part Grouping Explanation

Substitute parts for the 45J82R are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

• Resistance value: 82 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial form factor (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Physical dimensions: 0.343" Dia x 0.937" L (exact match required)
• Number of terminations: 2 (exact match required)

The 45J82RE meets all electrical and mechanical parameters identical to the 45J82R, differing only in packaging configuration (Bulk vs. standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 45J82R and 45J82RE are active production components from Ohmite's Ohmicone® 40 series with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• The 45J82R is RoHS non-compliant and suitable for applications without RoHS restrictions.
• The 45J82RE is ROHS3 compliant and required for applications subject to RoHS3 regulations or customer specifications mandating RoHS compliance.

Both parts maintain REACH Unaffected status and carry the same ECCN (EAR99) and HTSUS (8533.21.0080) classifications. Inventory availability is comparable for both variants.

Frequently Asked Questions (FAQ)

Q: Can the 45J82RE be used as a direct replacement for the 45J82R?

A: Yes. The 45J82RE is electrically and mechanically identical to the 45J82R. The primary difference is RoHS3 compliance status. Direct substitution is possible provided regulatory requirements do not mandate RoHS compliance.

Q: What is the difference between the 45J82R and 45J82RE?

A: The parts are identical in all electrical parameters (82 Ohms, ±5%, 5W, ±20ppm/°C), composition (wirewound), package type (axial), and physical dimensions (0.343" Dia x 0.937" L). The 45J82RE is ROHS3 compliant, while the 45J82R is RoHS non-compliant. Packaging configuration also differs (Bulk vs. standard).

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

A: No. Both parts share identical physical dimensions (0.343" Dia x 0.937" L / 8.70mm x 23.80mm) and temperature coefficient (±20ppm/°C).

Q: Which part should I select for RoHS-regulated applications?

A: The 45J82RE is ROHS3 compliant and must be used for applications subject to RoHS3 regulations or customer specifications requiring RoHS compliance.

Q: Is the axial package compatible with standard through-hole PCB layouts?

A: Yes. Both parts feature standard axial form factor with 2 terminations, compatible with conventional through-hole PCB designs and breadboard applications.
