Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 41F330 are qualified based on the following critical parameters:

• Resistance value: 330 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)

The identified substitutes maintain these core electrical and mechanical specifications. Variations in temperature coefficient, physical dimensions, and compliance certifications are noted but do not disqualify substitution eligibility within the defined parameter scope.

Parameter Comparison

Engineering Selection Recommendations

41F330E (Ohmite): Direct manufacturer equivalent with identical electrical specifications and physical dimensions. Achieves ROHS3 compliance, addressing regulatory requirements absent in the main part. Maintains the same temperature coefficient (±20ppm/°C) and series designation (Ohmicone® 40). Recommended for applications requiring RoHS compliance without dimensional constraints.

ALSR01330R0FE12 (Vishay Dale): Functionally equivalent with identical resistance, tolerance, and power rating. Provides ROHS3 compliance and moisture-resistant construction. Temperature coefficient is ±30ppm/°C (versus ±20ppm/°C for the main part). Physical dimensions are slightly smaller (0.110" Dia x 0.406" L). Suitable for applications where compact form factor and moisture resistance are beneficial, with acceptance of the higher temperature coefficient specification.

Frequently Asked Questions (FAQ)

Q: Can the 41F330E be used as a direct replacement for the 41F330?

A: Yes. The 41F330E maintains identical electrical specifications (330 Ohms ±1%, 1W wirewound) and physical dimensions (0.126" Dia x 0.437" L). The primary distinction is RoHS3 compliance in the 41F330E versus non-compliance in the 41F330.

Q: What is the significance of the temperature coefficient difference between the main part and ALSR01330R0FE12?

A: The ALSR01330R0FE12 has a temperature coefficient of ±30ppm/°C compared to ±20ppm/°C for the 41F330. This indicates slightly greater resistance variation across temperature ranges. Selection depends on application temperature stability requirements.

Q: Are there physical space constraints when substituting with ALSR01330R0FE12?

A: The ALSR01330R0FE12 has smaller dimensions (0.110" Dia x 0.406" L) compared to the 41F330 (0.126" Dia x 0.437" L). This may be advantageous in space-constrained designs but requires verification of PCB layout compatibility.

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

A: Both 41F330E and ALSR01330R0FE12 are ROHS3 compliant. The 41F330E is recommended for applications requiring identical temperature coefficient performance. The ALSR01330R0FE12 is suitable when moisture resistance and compact dimensions are additional requirements.

Q: Are all substitute parts currently in stock?

A: Yes. The 41F330E has 1211 pieces in stock, and the ALSR01330R0FE12 has 1010 pieces in stock, both classified as new original inventory.
