Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 40F10RE is determined by matching the following critical parameters: resistance value (10 Ohms), tolerance (±1%), power rating (10W), composition (wirewound), package configuration (axial), and temperature coefficient (±20ppm/°C). Parts meeting these specifications are classified as parametric equivalents or similar alternatives based on dimensional alignment and compliance certifications.

The 40F10R (Ohmite) qualifies as a parametric equivalent, sharing identical electrical specifications and package geometry. The RS01010R00FE73 (Vishay Dale) qualifies as a similar alternative, maintaining all critical electrical parameters with minor dimensional variation and enhanced moisture resistance features.

Parameter Comparison

Engineering Selection Recommendations

The 40F10R serves as a direct parametric equivalent with identical electrical and mechanical specifications. Selection of this part is appropriate when packaging format (bulk versus box) aligns with procurement requirements. However, RoHS non-compliance status must be evaluated against application regulatory requirements.

The RS01010R00FE73 provides an alternative with full ROHS3 compliance and moisture-resistant construction. Dimensional variation (0.375" diameter versus 0.406", and 1.780" length versus 1.902") requires verification of PCB layout and mechanical clearance constraints. This part is suitable for applications requiring enhanced environmental protection and regulatory compliance.

The 40F10RE remains the primary specification when RoHS compliance and exact dimensional matching are mandatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 40F10R replace the 40F10RE in all applications? A: The 40F10R matches all critical electrical parameters and dimensions. However, RoHS non-compliance status requires evaluation against your application's regulatory requirements before substitution.

Q: What are the dimensional differences between 40F10RE and RS01010R00FE73? A: The RS01010R00FE73 has a smaller diameter (0.375" versus 0.406") and shorter length (1.780" versus 1.902"). PCB layout and mechanical clearance must be verified before substitution.

Q: Is the RS01010R00FE73 suitable for moisture-sensitive applications? A: The RS01010R00FE73 includes moisture-resistant construction. The 40F10RE and 40F10R do not specify this feature. Application environment requirements should guide selection.

Q: Are all three parts suitable for the same operating temperature range? A: The 40F10RE and RS01010R00FE73 specify operating ranges of -55°C to 275°C and -65°C to 250°C respectively. The 40F10R does not specify an operating temperature range in available data. Application temperature requirements must be confirmed.

Q: What packaging formats are available? A: The 40F10RE is supplied in box packaging. The 40F10R is supplied in bulk. The RS01010R00FE73 is supplied in cut tape format. Procurement and assembly processes should guide packaging selection.
