Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7181.5001 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Fuse size: 0.197" Dia (5mm)
• Mounting type: Through Hole
• Fuse type: Cartridge
• Number of circuits: 1
• Orientation: Horizontal
• Termination style: PC Pin

Substitution Categories:

Direct Equivalent (Identical Specifications): Part 52000001009 (Littelfuse Inc.) matches all primary parameters including current rating (6.3A) and voltage rating (250V), providing a direct functional replacement.

Partial Equivalent (Compatible with Parameter Variance): Part 0751.0062 (SCHURTER Inc.) maintains fuse size, mounting type, and termination compatibility but differs in current rating (10A vs. 6.3A) and lacks specified voltage rating. Part 0031.8201 (SCHURTER Inc.) is a fuse block variant with higher voltage rating (500V) and increased current capacity (10A), compatible in fuse size and mounting but differs in fuseholder type (block vs. clip).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Part 52000001009 (Littelfuse Inc., Series 520) is the primary substitute. This part maintains identical electrical specifications (6.3A, 250V) and mechanical compatibility (5mm fuse size, through-hole clip configuration). Both the main part and this substitute are ROHS3 compliant and REACH unaffected. The substitute is currently in active production status with substantial inventory availability (20,300 pcs).

For Higher Current Applications: Part 0751.0062 (SCHURTER Inc., Series OG) accommodates 10A current rating while maintaining 5mm fuse size and clip-type fuseholder configuration. This part is suitable where circuit protection requirements exceed 6.3A. Voltage rating is not specified for this part; circuit design must confirm 250V minimum adequacy. This part is active production status with high inventory (92,336 pcs).

For Higher Voltage Applications: Part 0031.8201 (SCHURTER Inc., Series OGN) provides 500V voltage rating with 10A current capacity. This part transitions from clip to block fuseholder type and accommodates 5mm x 20mm fuse dimensions. Selection of this part requires PCB layout modification to accommodate the block configuration. This part is active production status with high inventory (144,048 pcs).

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity with the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can 52000001009 be used as a direct replacement for 7181.5001? A: Yes. Part 52000001009 matches all critical electrical and mechanical parameters: 6.3A current rating, 250V voltage rating, 5mm fuse size, through-hole mounting, clip-type fuseholder, and PC pin termination. Both parts are ROHS3 compliant.

Q: What is the difference between the clip and block fuseholder types? A: Clip-type fuseholders (7181.5001, 52000001009, 0751.0062) use spring-loaded contacts to retain the fuse cartridge. Block-type fuseholders (0031.8201) use a different mechanical retention method. These are not interchangeable without PCB layout modification.

Q: Can 0751.0062 be used in place of 7181.5001? A: Part 0751.0062 is mechanically compatible (5mm fuse size, through-hole clip configuration) but has a higher current rating (10A vs. 6.3A). The voltage rating for 0751.0062 is not specified. Use this part only if circuit design confirms voltage adequacy and the higher current rating does not compromise protection requirements.

Q: Why is 0031.8201 listed as a substitute if it uses a block instead of a clip? A: Part 0031.8201 is listed as a similar alternative for applications where higher voltage (500V) and current (10A) ratings are required. The block configuration requires PCB layout modification and is not a direct mechanical replacement.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts (52000001009, 0751.0062, 0031.8201) are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part 7181.5001.

Q: What is the inventory status of substitute parts? A: Part 52000001009 has 20,300 pcs in stock. Part 0751.0062 has 92,336 pcs in stock. Part 0031.8201 has 144,048 pcs in stock. All substitutes are in active production.
