Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 42J35R is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 35 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Termination count: 2

The Ohmite 42J35RE meets all these requirements and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is packaging format and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both the 42J35R and 42J35RE are active products from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging needs.

The 42J35R is suitable for applications where RoHS non-compliant components are acceptable or where standard packaging is preferred. The 42J35RE provides ROHS3 compliance, making it the appropriate choice for designs subject to RoHS directives or customer specifications requiring RoHS-compliant components. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 42J35RE be used as a direct replacement for the 42J35R?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between the standard and bulk packaging options?

A: The 42J35R uses standard packaging, while the 42J35RE is supplied in bulk packaging. Both formats contain the same component with identical specifications. Packaging selection depends on procurement volume and handling requirements.

Q: Are there any compliance considerations when substituting between these parts?

A: Yes. The 42J35RE is ROHS3 compliant, while the 42J35R is RoHS non-compliant. If your design or customer requirements mandate RoHS compliance, the 42J35RE must be selected. Both parts are REACH Unaffected.

Q: Do these parts have identical physical dimensions?

A: Yes. Both the 42J35R and 42J35RE measure 0.220" Dia x 0.406" L (5.60mm x 10.30mm) and are suitable for identical PCB layouts and mechanical assemblies.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts have a temperature coefficient of ±20ppm/°C, ensuring stable resistance performance across the operating temperature range.
