Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 40J200 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 200 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature Coefficient: ±20ppm/°C (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Physical Dimensions: 0.406" Dia x 1.902" L (exact match required)

The Ohmite 40J200E qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, physical dimensions, and axial package configuration. The primary distinction lies in packaging format (Bulk vs. standard) and compliance certifications, with 40J200E offering RoHS compliance and extended operating temperature range documentation.

Parameter Comparison

Engineering Selection Recommendations

Both the 40J200 and 40J200E are active products from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

40J200: Select this part when RoHS non-compliant components are acceptable for the application and when the standard packaging format is preferred.

40J200E: Select this part when RoHS compliance is required by design specifications or regulatory requirements. This variant also provides documented operating temperature range (-55°C ~ 275°C) and higher inventory availability (1198 units vs. 709 units). The Moisture Sensitivity Level rating of 1 (Unlimited) indicates no moisture-related handling restrictions.

Both parts are manufactured by Ohmite and carry the same ECCN (EAR99) and HTSUS (8533.21.0080) classifications, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 40J200E be used as a direct replacement for the 40J200?

A: Yes. The 40J200E is a parametric equivalent with identical resistance (200 Ohms), tolerance (±5%), power rating (10W), composition (wirewound), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). Both parts use axial through-hole packaging with 2 terminations. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the 40J200 and 40J200E?

A: The primary differences are packaging format (Bulk vs. standard), RoHS compliance status (non-compliant vs. compliant), and documented operating temperature range. The 40J200E provides explicit temperature range documentation (-55°C ~ 275°C) and RoHS compliance certification. Electrical performance and physical dimensions are identical.

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

A: If RoHS compliance is required, specify the 40J200E. If RoHS compliance is not a design requirement, either part is acceptable. The 40J200E also offers higher inventory availability and documented thermal operating limits.

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

A: No. Both parts are axial through-hole resistors with identical physical dimensions (0.406" Dia x 1.902" L / 10.30mm x 48.30mm). They share the same footprint and mounting requirements.

Q: What does the Moisture Sensitivity Level (MSL) rating mean?

A: The 40J200E carries an MSL rating of 1 (Unlimited), indicating that this component has no moisture sensitivity restrictions and requires no special moisture-control handling during storage or assembly.
