Equivalent & Substitute Parts for 0977005.MXP

Part Overview

The 0977005.MXP is a 5A ceramic cartridge fuse manufactured by Littelfuse Inc., rated for 500V AC and 450V DC operation. This slow-blow fuse is designed for 5mm x 20mm holder-based applications and is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit higher voltage ratings or improved breaking capacity specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0977005.MXP is determined by the following critical parameters:

• Current Rating: Must be 5 A (exact match required)
• Package / Case: Must be 5mm x 20mm (physical compatibility with existing holders)
• Fuse Type: Must be Cartridge, Ceramic (functional equivalence)
• Response Time: Must be Slow Blow (application-specific requirement)
• Mounting Type: Must require holder-based installation (system compatibility)

The substitute part 0ADKC5000-BE meets all mandatory substitution criteria. While this part features higher voltage ratings (600V AC / 500V DC) and improved breaking capacity (200A AC / 300A DC), these represent enhanced specifications that do not prevent substitution in applications designed for the original 0977005.MXP ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the 0977005.MXP and 0ADKC5000-BE are active production components with full regulatory compliance. The 0977005.MXP carries CE, PSE, and SEMKO approvals, while the 0ADKC5000-BE carries cURus certification. Both components meet RoHS3 and REACH compliance requirements.

Selection between these parts should be based on:

• Certification Requirements: Verify that the required approval agency (CE, PSE, SEMKO, or cURus) aligns with your application's regulatory framework
• Voltage System Design: The 0ADKC5000-BE provides higher voltage margins (600V AC / 500V DC) suitable for systems operating near the upper limits of the 0977005.MXP ratings
• Breaking Capacity Requirements: Applications requiring higher fault current interruption capability should specify the 0ADKC5000-BE (200A AC / 300A DC versus 100A AC / 200A DC)
• Inventory Availability: Current stock levels are 1694 pcs for 0977005.MXP and 2845 pcs for 0ADKC5000-BE

Frequently Asked Questions (FAQ)

Q: Can the 0ADKC5000-BE directly replace the 0977005.MXP in existing designs?

A: Yes. Both components share identical current ratings (5A), package dimensions (5mm x 20mm), response characteristics (Slow Blow), and operating temperature ranges (-55°C ~ 125°C). Physical installation in existing holders is compatible.

Q: What are the differences in voltage ratings between these parts?

A: The 0977005.MXP is rated 500V AC / 450V DC. The 0ADKC5000-BE is rated 600V AC / 500V DC. The substitute part provides higher voltage capability, which does not restrict its use in applications designed for the original part's lower ratings.

Q: Are there differences in breaking capacity?

A: Yes. The 0977005.MXP has a breaking capacity of 100A AC and 200A DC at rated voltage. The 0ADKC5000-BE provides 200A AC and 300A DC. Higher breaking capacity does not prevent substitution in applications designed for the original part.

Q: Which certifications apply to each part?

A: The 0977005.MXP carries CE, PSE, and SEMKO approvals. The 0ADKC5000-BE carries cURus certification. Verify that the required certification for your application is present on the selected part.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 0977005.MXP and 0ADKC5000-BE are ROHS3 compliant and REACH unaffected.

Q: What is the melting I²t specification, and does it differ between parts?

A: The 0977005.MXP has a melting I²t of 91. The 0ADKC5000-BE has a melting I²t of 50. This parameter reflects thermal energy dissipation characteristics and should be considered in applications with specific thermal response requirements.
