Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0312035.VXP is determined by the following critical parameters:

• Current Rating: 35 A (exact match required)
• Voltage Rating (AC): 32 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. The Littelfuse variants (0312035.HXP and 0312035.MXP) are parametrically identical to the main part number 0312035.VXP across all specified electrical and mechanical parameters.

The Eaton BK/AGC-35-R part meets all critical substitution criteria for current rating, voltage rating, fuse type, response time, package configuration, and physical dimensions. This part carries CSA and UL approval certifications and maintains the required operating temperature range. Minor variations in breaking capacity (70A versus 300A) and melting I²t (7350 versus 7531) do not affect functional interchangeability for standard circuit protection applications within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can 0312035.HXP and 0312035.MXP be used interchangeably with 0312035.VXP?

A: Yes. These Littelfuse variants are parametrically equivalent across all critical electrical and mechanical specifications, including current rating, voltage rating, fuse type, response time, package configuration, and physical dimensions.

Q: Is the Eaton BK/AGC-35-R a direct substitute for the Littelfuse 0312035.VXP?

A: Yes. The BK/AGC-35-R meets all required substitution criteria for current rating (35 A), voltage rating (32 V AC), fuse type (Cartridge, Glass), response time (Fast Blow), package configuration (3AB, 3AG), and physical dimensions (0.250" Dia x 1.250" L). The part is Active status and ROHS3 compliant.

Q: What holder types are compatible with these fuse cartridges?

A: All listed parts require 3AB or 3AG holder configurations. Physical dimensions of 0.250" diameter by 1.250" length ensure compatibility with standard holders designed for these package types.

Q: Are there differences in performance characteristics between the Littelfuse and Eaton options?

A: The Littelfuse variants (0312035.VXP, 0312035.HXP, 0312035.MXP) are identical in all specified parameters. The Eaton BK/AGC-35-R exhibits a lower breaking capacity (70A versus 300A) and slightly different melting I²t (7350 versus 7531) and DC cold resistance (0.0021 Ohms versus 0.0013 Ohms). These differences do not affect interchangeability for applications within the specified 35 A, 32 V rating.

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

A: All listed parts operate across the temperature range of -55°C to 125°C, ensuring functionality across standard industrial and commercial application environments.
