Ohmite 42J220 220 Ohm 2W Axial Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 42J220 is a 220 Ohm, 2W axial wirewound through-hole resistor with ±5% tolerance, part of the Ohmicone® 40 series. This component is actively manufactured and maintained in production inventory. Substitute parts are identified based on identical electrical specifications and mechanical compatibility to support procurement flexibility, inventory management, and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 42J220 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must remain constant for a part to qualify as a direct substitute:

• Resistance value: 220 Ohms (exact match)
• Power rating: 2W (exact match)
• Tolerance: ±5% (exact match)
• Composition: Wirewound (exact match)
• Package type: Axial (exact match)
• Temperature coefficient: ±20ppm/°C (exact match)
• Physical dimensions: 0.220" Dia x 0.406" L (exact match)

The 42J220E meets all these criteria and is classified as a parametric equivalent. Differences in packaging format (Bulk vs. standard), RoHS compliance status, and operating temperature range do not affect electrical or mechanical interchangeability in the circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the 42J220 and 42J220E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

• RoHS Compliance Requirements: If the application or end-market requires RoHS compliance, the 42J220E is the appropriate selection. The 42J220 is RoHS non-compliant and should be used only in applications where RoHS exemptions apply.

• Operating Temperature Documentation: The 42J220E provides an explicit operating temperature range of -55°C to 275°C. If circuit design documentation requires a defined temperature specification, the 42J220E offers this clarity.

• Inventory and Packaging: The 42J220E maintains higher inventory levels (2661 Pcs vs. 986 Pcs) and is available in Bulk packaging, supporting larger production runs and supply chain flexibility.

• Circuit Interchangeability: For applications where RoHS status and temperature documentation are not constraints, both parts are electrically and mechanically interchangeable without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 42J220E be used as a direct replacement for the 42J220 in existing designs?

A: Yes, the 42J220E is electrically and mechanically identical to the 42J220. Both parts have the same resistance value (220 Ohms), power rating (2W), tolerance (±5%), composition (Wirewound), package type (Axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.220" Dia x 0.406" L). No circuit modifications are required for substitution.

Q: What is the difference between the 42J220 and 42J220E?

A: The primary differences are RoHS compliance status and operating temperature documentation. The 42J220E is RoHS Compliant with a defined operating temperature range of -55°C to 275°C, while the 42J220 is RoHS non-compliant with no specified operating temperature range. Electrically and mechanically, both parts are identical.

Q: Which part should I specify for a new design?

A: If your application or end-market requires RoHS compliance, specify the 42J220E. If RoHS compliance is not a requirement and the design does not mandate a defined operating temperature range, either part is acceptable. The 42J220E is recommended for new designs due to its RoHS compliance status and higher inventory availability.

Q: Are there any package or form factor differences between these parts?

A: No. Both the 42J220 and 42J220E are supplied in Axial package type with identical physical dimensions of 0.220" Dia x 0.406" L (5.60mm x 10.30mm). They are mechanically interchangeable on PCBs designed for axial through-hole resistors of this size.

Q: Can I mix 42J220 and 42J220E parts in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same circuit and production batch. However, if RoHS compliance documentation is required for the final product, ensure that all resistors in the assembly meet the applicable RoHS requirements.

Q: What certifications and compliance standards apply to these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS 8533.21.0080. The 42J220E is RoHS Compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited). The 42J220 is RoHS non-compliant and REACH Unaffected. Compliance requirements should be verified against your specific application and regional regulations.
