Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATM-30LP are grouped into two primary categories based on electrical and mechanical compatibility:

Category 1: Direct Electrical & Mechanical Equivalents (Miniature Blade, 30 A, 32 V DC)

Parts in this category maintain identical current rating (30 A), DC voltage rating (32 V), fast-blow response time, miniature blade form factor, and 1 kA breaking capacity. These parts are fully interchangeable with the ATM-30LP in applications requiring these exact specifications. Substitutes include Littelfuse MINI® 297 series parts: 0297030.L, 0297030.U, 0297030.WXNV, and 0297030.WXT.

Category 2: Functional Equivalents with Form Factor Variation (Micro Blade, 30 A, 32 V DC)

The Littelfuse MICRO2™ 327 series part 0327030.YX2S maintains identical electrical ratings (30 A, 32 V DC, fast-blow operation, 1 kA breaking capacity) but uses a micro blade form factor instead of miniature. This part is functionally equivalent but requires verification of holder compatibility due to the smaller physical dimensions (0.358" L x 0.150" W x 0.311" H versus 0.430" L x 0.150" W x 0.347" H).

Category 3: Voltage-Rated Variants (Miniature Blade, 30 A, Higher DC Voltage)

The Littelfuse MINI® 997 series part 0997030.WXN maintains the miniature blade form factor and 30 A current rating but is rated for 58 V DC instead of 32 V DC. This part is suitable only for applications where the higher voltage rating is required or acceptable.

Category 4: AC/DC Dual-Rated Variants (Miniature Blade, 30 A, 32 V AC/DC)

Littelfuse MINI® series parts 0MIN030.HXGLO, 0MIN030.MXGLO, 0MIN030.V, and 0MIN030.VP are rated for both 32 V AC and 32 V DC at 30 A with fast-blow response and miniature blade form factor. These parts are suitable for applications requiring AC voltage capability in addition to DC operation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Interchangeability)

The Littelfuse MINI® 297 series parts 0297030.L, 0297030.U, 0297030.WXNV, and 0297030.WXT are the preferred direct substitutes for the ATM-30LP. All four parts maintain identical electrical specifications (30 A, 32 V DC, fast-blow operation, 1 kA breaking capacity), miniature blade form factor, and physical dimensions within 0.01 inches. All substitute parts are ROHS3 compliant and carry active product status. Parts 0297030.L and 0297030.U include UL and SAE approvals respectively, providing additional certification coverage.

Secondary Substitutes (Form Factor Variation)

The Littelfuse MICRO2™ 327 part 0327030.YX2S maintains full electrical equivalence (30 A, 32 V DC, 1 kA breaking capacity) but uses a micro blade form factor with reduced physical dimensions. This part is suitable only when the smaller form factor is compatible with the fuse holder assembly. Verification of holder compatibility is required before selection.

Voltage-Rated Alternative

The Littelfuse MINI® 997 part 0997030.WXN is suitable for applications where 58 V DC rating is required or where the higher voltage rating provides system margin. This part maintains the miniature blade form factor and 30 A current rating but is not a direct substitute for 32 V DC-only applications.

AC/DC Dual-Rated Options

The Littelfuse MINI® series parts 0MIN030.HXGLO, 0MIN030.MXGLO, 0MIN030.V, and 0MIN030.VP are suitable for applications requiring both AC and DC voltage capability at 32 V. These parts maintain the miniature blade form factor, 30 A current rating, and fast-blow response. Part 0MIN030.VP is supplied in a 5-pack card configuration, while the others are supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse MINI® 297 series parts directly replace the ATM-30LP?

A: Yes. Parts 0297030.L, 0297030.U, 0297030.WXNV, and 0297030.WXT are direct electrical and mechanical equivalents. All maintain 30 A current rating, 32 V DC voltage rating, fast-blow response, miniature blade form factor, and 1 kA breaking capacity. Physical dimensions are identical within manufacturing tolerance (10.90mm vs 10.92mm length, 3.80mm vs 3.81mm width, 8.80mm vs 8.81mm height).

Q: What is the difference between the Littelfuse MINI® 297 and MICRO2™ 327 series?

A: Both series maintain identical electrical ratings (30 A, 32 V DC, fast-blow, 1 kA breaking capacity). The primary difference is physical form factor: MINI® 297 uses a miniature blade measuring 10.90 x 3.80 x 8.80mm, while MICRO2™ 327 uses a micro blade measuring 9.10 x 3.80 x 7.90mm. The micro blade is smaller and requires verification of holder compatibility before substitution.

Q: When should the Littelfuse MINI® 997 series part 0997030.WXN be selected?

A: The 0997030.WXN is rated for 58 V DC instead of 32 V DC. Select this part only when the application requires or benefits from the higher voltage rating. It is not a direct substitute for 32 V DC-only applications.

Q: What is the difference between bulk and card packaging for the MINI® series?

A: Part 0MIN030.VP is supplied in a 5-pack card configuration, while parts 0MIN030.HXGLO, 0MIN030.MXGLO, and 0MIN030.V are supplied in bulk packaging. Electrical and mechanical specifications are identical; packaging differs only in quantity and presentation format.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ATM-30LP is RoHS Compliant, and all listed substitute parts are ROHS3 Compliant, meeting current environmental and material restriction requirements.

Q: What certifications should be considered when selecting a substitute?

A: The ATM-30LP carries no specified approval agency. Among substitutes, parts 0297030.L and 0297030.U include UL and SAE approvals. Parts 0MIN030.HXGLO, 0MIN030.MXGLO, and 0MIN030.V include SAE and UL approvals. Part 0297030.WXT includes UR approval. Select based on application certification requirements.

Q: Can AC-rated fuses be used in DC-only applications?

A: The AC/DC dual-rated parts (0MIN030.HXGLO, 0MIN030.MXGLO, 0MIN030.V, 0MIN030.VP) are rated for both 32 V AC and 32 V DC operation. These parts are suitable for DC-only applications and provide additional flexibility for systems that may require AC capability.
