Littelfuse 032601.6VXP Ceramic Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 032601.6VXP is a 1.6 A ceramic fuse cartridge rated for 250 V AC and 125 V DC operation. This slow-blow cartridge fuse requires a 3AB or 3AG holder and is designed for applications requiring reliable overcurrent protection in industrial and commercial equipment. The part maintains active product status with full compliance to CE, CSA, PSE, and UL approval agencies. Substitute parts are necessary when primary inventory is unavailable, when alternative manufacturers are preferred for supply chain diversification, or when specific performance characteristics of alternative designs better suit application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 032601.6VXP is determined by the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Fuse Type: Cartridge (ceramic or glass acceptable based on application)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

Secondary Consideration:

• Voltage Rating - DC: 125 V preferred; lower DC ratings acceptable only in applications where DC voltage does not exceed the substitute part's rating

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and direct manufacturer alternatives (same current and AC voltage with acceptable variations in secondary parameters).

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 032601.6HXP is the primary parametric equivalent to the 032601.6VXP. Both parts are manufactured by Littelfuse within the 326 series, share identical electrical ratings (1.6 A, 250 V AC, 125 V DC), mechanical dimensions, and response characteristics. Both maintain active product status with full CE, CSA, PSE, and UL certifications. This substitute provides direct interchangeability with no application modifications required.

SCHURTER 0001.2526 is a direct manufacturer alternative with matching current rating (1.6 A) and AC voltage rating (250 V). The primary distinction is the fuse element material: this part uses glass construction rather than ceramic. The DC voltage rating is reduced to 63 V, limiting applicability to systems where DC voltage does not exceed this threshold. Operating temperature range is narrower (-40°C to 85°C versus -55°C to 125°C). This substitute is suitable for AC-dominant applications or systems with DC voltage below 63 V. Approval agency coverage includes cURus certification.

Eaton BK/MDA-1-6/10-R is a manufacturer-recommended ceramic cartridge fuse with matching current (1.6 A) and AC voltage (250 V) ratings. DC voltage rating is not specified in available data. Mechanical dimensions and package compatibility are identical. Certifications include CE, CSA, and UL. This substitute is suitable for applications where DC voltage specification is not critical or where DC operation is not required.

Bel Fuse GSA 1.6-R is a manufacturer-recommended ceramic cartridge fuse with matching current (1.6 A) and AC voltage (250 V) ratings. DC voltage rating is not specified. Operating temperature range matches the primary part (-55°C to 125°C). Mechanical dimensions and package compatibility are identical. Certifications include CE, CSA, cULus, and PSE. This substitute provides broad approval agency coverage and is suitable for applications requiring extended temperature operation.

All substitute parts maintain ROHS3 compliance and are suitable for direct replacement in 3AB and 3AG holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0001.2526 be used as a direct replacement for the Littelfuse 032601.6VXP?

A: The SCHURTER 0001.2526 is mechanically and electrically compatible for AC applications. However, the DC voltage rating is reduced from 125 V to 63 V. Use this substitute only in applications where the DC voltage does not exceed 63 V. The glass fuse element provides different breaking characteristics compared to the ceramic design of the primary part.

Q: What is the difference between ceramic and glass fuse cartridges?

A: Both ceramic and glass cartridge fuses provide slow-blow protection at 1.6 A and 250 V AC. The primary differences are in breaking capacity, melting I²t characteristics, and DC voltage ratings. The SCHURTER 0001.2526 (glass) has a lower melting I²t (4.2 versus 45) and different breaking capacity specifications. Selection between ceramic and glass depends on specific application requirements for breaking capacity and thermal response.

Q: Are all substitute parts compatible with 3AB and 3AG holders?

A: Yes. All listed substitute parts are designed for 3AB and 3AG holder compatibility with identical mechanical dimensions of 0.250" diameter by 1.250" length (6.35mm x 31.75mm), with minor length variations of ±0.002" that do not affect holder compatibility.

Q: Which substitute part has the broadest approval agency coverage?

A: The Bel Fuse GSA 1.6-R includes CE, CSA, cULus, and PSE certifications. The Littelfuse 032601.6HXP also includes PSE certification in addition to CE, CSA, and UL. Both parts meet or exceed the certification requirements of the primary part.

Q: Can I use the Eaton BK/MDA-1-6/10-R in a DC application?

A: The Eaton BK/MDA-1-6/10-R does not specify a DC voltage rating in available technical data. For applications requiring confirmed DC voltage protection, use the Littelfuse 032601.6VXP or 032601.6HXP (both rated 125 V DC) or the SCHURTER 0001.2526 (rated 63 V DC).

Q: What is the significance of the melting I²t value?

A: The melting I²t value indicates the thermal energy required to melt the fuse element. Lower values indicate faster thermal response. The primary part and its Littelfuse equivalent (032601.6HXP) have melting I²t values of 45, while the Eaton and SCHURTER alternatives have lower values (4.6 and 4.2 respectively), indicating faster response to overcurrent conditions. Selection depends on application requirements for protection speed versus inrush current tolerance.
