Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALFT-04-7 are identified based on strict alignment of the following critical parameters:

• Series membership (ALFT-04 family)
• Filter type (Signal Line)
• Number of lines (2-line configuration)
• Mounting type (Through Hole)
• Package configuration (Vertical, 4 PC Pin)
• Physical dimensions (34.00mm L x 18.00mm W x 31.80mm H)
• Operating temperature range (-25°C ~ 85°C)
• RoHS compliance status (ROHS3 Compliant)
• Product status (Active)

The ALFT-04-6 qualifies as a parametric equivalent within this product category. While inductance and DC resistance values differ from the main part, both components share identical mechanical, thermal, and compliance specifications, allowing substitution based on circuit requirements that accommodate the specified inductance and resistance parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ALFT-04-7 and ALFT-04-6 maintain Active product status and are ROHS3 compliant, ensuring long-term availability and regulatory compliance for new designs. Selection between these parts depends on circuit-specific inductance and DC resistance requirements. The ALFT-04-7 provides 4.5 mH inductance with 20mOhm DCR, while the ALFT-04-6 provides 3 mH inductance with 16mOhm DCR. Both components share identical mechanical footprints, thermal ratings, and package configurations, enabling direct substitution when electrical parameters align with design specifications.

Frequently Asked Questions (FAQ)

Q: Can ALFT-04-6 be used as a direct replacement for ALFT-04-7?
