Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MJS 4.6 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution compatibility are:

• Current Rating: 4.6 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Package / Case: 2AG, 5mm x 15mm (Axial)
• Response Time: Slow Blow
• Breaking Capacity @ Rated Voltage: 200 A
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 125°C

The MJS 4.6-R meets all these electrical and mechanical requirements and is classified as an active product with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The MJS 4.6-R is the direct substitute for the obsolete MJS 4.6. Both components share identical electrical ratings, mechanical dimensions, and thermal characteristics. The MJS 4.6-R carries active product status with current manufacturing availability. The MJS 4.6-R holds ROHS3 compliance, whereas the original MJS 4.6 is non-compliant. Both components maintain equivalent approval certifications (CE, CSA, PSE) with the MJS 4.6-R additionally certified as cULus. For new designs or component replacement in existing applications, the MJS 4.6-R is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MJS 4.6-R be used as a direct replacement for the MJS 4.6?

A: Yes. The MJS 4.6-R is electrically and mechanically equivalent to the MJS 4.6. Both components have identical current ratings (4.6 A), voltage ratings (250 V AC), fuse type (Cartridge, Glass), package dimensions (2AG, 5mm x 15mm), response time (Slow Blow), and breaking capacity (200 A).
