Equivalent & Substitute Parts for 0325020.MXF80P

Part Overview

The 0325020.MXF80P is a 20 A, 250 V AC ceramic cartridge fuse manufactured by Littelfuse Inc., designed for through-hole mounting in 3AB/3AG package format. This slow-blow fuse is rated for AC applications with a breaking capacity of 400 A at rated voltage and operates across a temperature range of -55°C to 125°C. The part maintains active product status and is ROHS3 compliant with full international approvals including CE, CSA, KC, METI, and UL certification.

Substitute parts are identified when they maintain electrical compatibility across core parameters: current rating, AC voltage rating, response time classification, package format, and mechanical dimensions. Alternative models may be required due to inventory availability, regional certification requirements, or DC voltage capability needs in dual-voltage applications.

Substitute Part Grouping Explanation

Substitute parts for the 0325020.MXF80P are qualified based on strict electrical and mechanical compatibility:

Primary Substitution Criteria:

• Current Rating: 20 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Through Hole (exact match required)
• Size / Dimension: 0.275" Dia x 1.288" L (6.99mm x 32.72mm) (exact match required)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Breaking Capacity: 400 A minimum at rated AC voltage
• Approval Agencies: CE, CSA, UL (baseline international certifications)

The substitute parts 0325020.MXDP and 0325020.MXP meet all primary substitution criteria. Both parts extend voltage capability to include 60 V DC rating, which does not compromise AC-only applications. Both maintain identical mechanical dimensions, response characteristics, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance. Selection between the main part and substitutes is determined by application voltage requirements and regional certification scope:

0325020.MXF80P is specified for AC-only applications where DC voltage rating is not required. This part carries approvals from CE, CSA, KC, METI, and UL, providing comprehensive international coverage including Japanese market certifications (KC, METI).

0325020.MXDP provides dual-voltage capability (250 V AC / 60 V DC) with approvals from CE, CSA, and UL. This part is suitable for applications requiring both AC and DC protection in a single component.

0325020.MXP also provides dual-voltage capability (250 V AC / 60 V DC) with expanded regional certifications including K-MARK and PSE approvals, extending coverage to Japanese and Korean markets. This part is optimal for applications requiring both AC and DC protection with broader regional compliance.

All three parts are manufactured by Littelfuse Inc. and share identical mechanical dimensions, thermal operating range, and response time characteristics. Selection should be based on specific application voltage requirements and required regional certifications.

Frequently Asked Questions (FAQ)

Q: Can 0325020.MXDP or 0325020.MXP be used as direct replacements for 0325020.MXF80P in AC-only circuits?

A: Yes. Both substitute parts maintain identical AC voltage rating (250 V), current rating (20 A), response time (Slow Blow), package format (3AB, 3AG), and mechanical dimensions (0.275" Dia x 1.288" L). The additional 60 V DC rating does not affect AC-only operation.

Q: What is the difference between 0325020.MXDP and 0325020.MXP?

A: Both parts share identical electrical specifications: 20 A, 250 V AC, 60 V DC, Slow Blow response, and 3AB/3AG package format. The primary difference is regional certification scope. 0325020.MXP includes K-MARK and PSE approvals in addition to CE, CSA, and UL, making it suitable for Japanese and Korean market applications. 0325020.MXDP carries CE, CSA, and UL approvals.

Q: Are the mechanical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions: 0.275" Dia x 1.288" L (6.99mm x 32.72mm). They are mechanically interchangeable in 3AB/3AG through-hole mounting applications.

Q: What is the operating temperature range for these fuses?

A: All three parts operate across -55°C to 125°C, providing identical thermal performance across the product family.

Q: Which part should be selected for applications requiring both AC and DC protection?

A: Both 0325020.MXDP and 0325020.MXP provide dual-voltage ratings (250 V AC / 60 V DC). Selection between these two should be based on required regional certifications. 0325020.MXP is recommended for applications requiring Japanese (PSE, K-MARK) or Korean market compliance.
