Substitute Part Grouping Explanation

Substitute parts for the 0325030.VXP are identified based on strict parametric equivalence within the Littelfuse 325 series ceramic fuse family. All substitute parts maintain identical electrical specifications: 30 A current rating, 250 V AC / 125 V DC voltage ratings, slow-blow response time, and 1690 melting I²t value. All substitute parts share the same mechanical form factor (3AB, 3AG, 1/4" x 1-1/4" axial package), identical breaking capacity (400 A AC, 600 A DC), and matching operating temperature range (-55°C ~ 125°C).

The substitution logic is based on the following key parameters that determine functional interchangeability:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 250 V AC / 125 V DC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 400 A AC, 600 A DC (exact match required)
• Melting I²t: 1690 (exact match required)

All substitute parts are manufactured by Littelfuse Inc. and maintain ROHS3 compliance and active product status.

Parameter Comparison

Engineering Selection Recommendations

All three parts (0325030.VXP, 0325030.HXP, and 0325030.MXP) are functionally equivalent and maintain active product status. Selection between these parts should be based on the following factors:

Certification Requirements: The 0325030.VXP carries CE, CSA, PSE, and UL approvals. The 0325030.HXP and 0325030.MXP include an additional K-MARK certification. If K-MARK certification is required for your application, select 0325030.HXP or 0325030.MXP. If K-MARK is not required, all three parts are suitable.

Inventory Availability: The 0325030.MXP has the highest inventory level at 16,311 units, followed by 0325030.HXP at 945 units, and 0325030.VXP at 900 units. For applications requiring immediate procurement or high-volume orders, 0325030.MXP provides superior supply chain availability.

Compliance Status: All parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory compliance for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0325030.HXP or 0325030.MXP for 0325030.VXP in my circuit?

A: Yes. All three parts are parametrically equivalent with identical current ratings (30 A), voltage ratings (250 V AC / 125 V DC), response time (slow blow), breaking capacity (400 A AC / 600 A DC), and mechanical form factor (3AB, 3AG, 1/4" x 1-1/4" axial). Direct substitution is supported without circuit modification.

Q: What is the difference between these three part numbers?

A: The electrical and mechanical specifications are identical. The primary differences are: (1) approval agency certifications, where 0325030.HXP and 0325030.MXP include K-MARK certification in addition to CE, CSA, PSE, and UL; and (2) inventory levels, with 0325030.MXP having significantly higher stock availability.

Q: Are these parts interchangeable in terms of physical mounting?

A: Yes. All three parts share the identical 3AB, 3AG package designation with dimensions of 0.275" diameter by 1.288" length (6.99 mm x 32.72 mm). They are all through-hole mounted components and are mechanically interchangeable in any circuit designed for this form factor.

Q: Which part should I select for new designs?

A: For new designs, 0325030.MXP is recommended due to superior inventory availability and extended supply chain security. If K-MARK certification is not required, 0325030.VXP is also suitable. All three parts maintain active product status and ROHS3 compliance.

Q: Do these parts have different thermal or electrical performance characteristics?

A: No. All three parts maintain identical operating temperature range (-55°C ~ 125°C), DC cold resistance (0.0019 Ohms), and melting I²t value (1690). Thermal and electrical performance is equivalent across all three part numbers.
