Littelfuse 0325030.HXP Ceramic Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0325030.HXP is a 30 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This slow-blow fuse is designed for through-hole mounting in 3AB/3AG form factor (1/4" x 1-1/4" axial) and is currently active in production. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative manufacturers meeting identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0325030.HXP is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Current Rating: 30 A
• Voltage Rating - AC: 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole

Secondary Compatibility Parameters (Allowable Variation):

• Voltage Rating - DC: 125 V minimum
• Breaking Capacity: 400 A AC minimum
• Melting I²t: 1690 nominal
• Operating Temperature: -55°C ~ 125°C preferred
• RoHS Compliance: ROHS3 Compliant

The 0325030.MXP (Littelfuse) is a parametric equivalent with identical specifications across all critical parameters. The 8020.0607.PT (SCHURTER) is a manufacturer-recommended substitute meeting all primary criteria with compatible secondary parameters. The 0001.2527 (SCHURTER) does not qualify as a direct substitute due to mismatched current rating (2 A vs. 30 A) and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

0325030.MXP (Littelfuse) is the primary equivalent substitute. It maintains identical electrical and mechanical specifications to the 0325030.HXP, including current rating, voltage ratings, response time, package form factor, and operating temperature range. Both parts carry the same approval agencies (CE, CSA, K-MARK, PSE, UL) and RoHS3 compliance status. This part is suitable for direct replacement in all applications.

8020.0607.PT (SCHURTER) is a manufacturer-recommended alternative. It matches all primary substitution criteria: 30 A current rating, 250 V AC, ceramic cartridge type, slow-blow response, 3AB/3AG package, and through-hole mounting. The melting I²t value (2050) is slightly elevated compared to the primary part (1690), and the operating temperature range is narrower (-40°C ~ 85°C vs. -55°C ~ 125°C). Approval is limited to cURus certification. This part is suitable for applications where the narrower temperature range and alternative certification profile are acceptable.

0001.2527 (SCHURTER) is not recommended as a substitute. The current rating (2 A) and DC voltage rating (63 V) are incompatible with the 0325030.HXP specifications. This part is listed in the original substitute field but does not meet the electrical requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can 0325030.MXP be used as a direct replacement for 0325030.HXP?

A: Yes. The 0325030.MXP is a parametric equivalent with identical current rating (30 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (slow blow), package form factor (3AB/3AG, 1/4" x 1-1/4"), and mounting type (through hole). Both parts carry identical approval agencies and RoHS compliance status.

Q: What are the key differences between 8020.0607.PT and 0325030.HXP?

A: The 8020.0607.PT matches the primary electrical and mechanical specifications (30 A, 250 V AC, ceramic cartridge, slow blow, 3AB/3AG package, through hole). Differences include: melting I²t (2050 vs. 1690), operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C), and approval agencies (cURus vs. CE, CSA, K-MARK, PSE, UL). The 8020.0607.PT does not specify a DC voltage rating.

Q: Is 0001.2527 compatible with applications designed for 0325030.HXP?

A: No. The 0001.2527 has a current rating of 2 A and DC voltage rating of 63 V, which are incompatible with the 30 A / 125 V DC specifications of the 0325030.HXP. Additionally, it is a glass cartridge fuse requiring a holder, not a ceramic through-hole fuse. This part is not suitable for substitution.

Q: What mounting considerations apply to these substitute parts?

A: All three parts use the 3AB/3AG form factor (1/4" x 1-1/4" axial). The 0325030.HXP and 0325030.MXP are through-hole ceramic cartridges with identical dimensions (0.275" Dia x 1.288" L). The 8020.0607.PT is also through-hole ceramic with similar dimensions (0.270" Dia x 1.291" L). The 0001.2527 is a glass cartridge requiring a separate holder and is not mechanically compatible.

Q: Are there temperature range limitations when selecting a substitute?

A: The 0325030.HXP and 0325030.MXP operate across -55°C ~ 125°C. The 8020.0607.PT operates across -40°C ~ 85°C. If the application requires operation below -40°C or above 85°C, the 8020.0607.PT is not suitable. The 0325030.MXP maintains the full temperature range of the original part.

Q: Do all substitute parts meet the same regulatory certifications?

A: No. The 0325030.HXP and 0325030.MXP carry CE, CSA, K-MARK, PSE, and UL approvals. The 8020.0607.PT carries cURus certification. Applications requiring specific regulatory approvals (such as UL or PSE) should use the 0325030.MXP to maintain certification consistency.
