Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 20J82R is determined by strict equivalence across the following parameters:

• Resistance value: 82 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety characteristics

The identified substitute, Ohmite 20J82RE, matches all electrical and mechanical parameters. The primary distinction is packaging format (Bulk versus standard packaging) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J82R and 20J82RE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The 20J82RE is RoHS Compliant, while the 20J82R is RoHS non-compliant. Applications subject to RoHS regulations require the 20J82RE.

Packaging Requirements: The 20J82R is supplied in standard packaging, while the 20J82RE is supplied in Bulk packaging. Procurement volume and handling requirements should determine the appropriate packaging format.

Inventory Availability: The 20J82RE has higher current inventory (1270 units) compared to the 20J82R (766 units), supporting faster fulfillment for high-volume orders.

Moisture Sensitivity: The 20J82RE specifies MSL 1 (Unlimited), indicating superior moisture resistance characteristics compared to the 20J82R.

Frequently Asked Questions (FAQ)

Q: Can the 20J82RE be used as a direct replacement for the 20J82R?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, tolerances, power ratings, physical dimensions, and temperature coefficients. The 20J82RE is suitable for direct substitution in all applications where the 20J82R is specified.

Q: What is the difference between the 20J82R and 20J82RE?

A: The primary differences are packaging format (standard versus Bulk), RoHS compliance status (non-compliant versus Compliant), and moisture sensitivity level classification. Electrical and mechanical performance are identical.

Q: Which part should be selected for RoHS-regulated applications?

A: The 20J82RE is RoHS Compliant and must be used for applications subject to RoHS directives. The 20J82R is not RoHS compliant and is unsuitable for such applications.

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

A: No. Both parts share identical temperature coefficients (±30ppm/°C), power ratings (10W), and thermal characteristics. Performance in thermal cycling and high-temperature environments is equivalent.

Q: What packaging considerations apply to these parts?

A: The 20J82R is supplied in standard packaging, while the 20J82RE is supplied in Bulk packaging. Bulk packaging is typically used for high-volume procurement and automated assembly processes. Standard packaging is suitable for lower-volume applications and manual assembly.
