Littelfuse 38215000000 Board Mount Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 38215000000 is a 5 A, 250 V AC/DC board mount fuse with radial, can-style vertical packaging. This through-hole component is part of the TR5® 382 series and is actively produced. The fuse features slow-blow response characteristics and is designed for applications requiring reliable overcurrent protection in industrial and commercial equipment. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements where alternative certifications or performance characteristics are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Littelfuse 38215000000 is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Response Time: Slow Blow (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Physical Dimensions: 0.335" Dia x 0.315" H / 8.50mm x 8.00mm (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in breaking capacity, melting I²t, DC cold resistance, and approval agencies do not preclude substitution when the above parameters are identical. The substitute parts are grouped as parametric equivalents (Littelfuse 37215000001 and 37415000000) and direct manufacturer alternatives (SCHURTER 0034.6982).

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and meet the core electrical and mechanical substitution criteria. Selection among these parts should be based on the following considerations:

Littelfuse 38215000000 (TR5® 382): Primary specification with 100 A breaking capacity and 121.25 melting I²t. Approved by CQC, cURus, KC, PSE/JET, SEMKO, and VDE. Recommended for applications requiring the broadest certification coverage.

Littelfuse 37215000001 (TR5® 372): Parametric equivalent with 50 A breaking capacity and 115 melting I²t. Approved by CCC, cURus, PSE, SEMKO, and VDE. Suitable for applications where lower breaking capacity is acceptable and CQC or KC certification is not required.

Littelfuse 37415000000 (TR5® 374): Parametric equivalent with 50 A breaking capacity and 59 melting I²t. Approved by CSA and cULus only. Suitable for North American applications where CSA/cULus certification is the primary requirement.

SCHURTER 0034.6982 (MXT 250): Direct manufacturer alternative with 100 A breaking capacity and 155 melting I²t. Approved by cURus and PSE/JET. Height dimension is 0.335" (8.50mm) versus 0.315" (8.00mm) for Littelfuse parts. Suitable for applications where SCHURTER certification is acceptable and physical height tolerance permits the 0.020" (0.50mm) difference.

Frequently Asked Questions (FAQ)

Q: Can I use Littelfuse 37215000001 or 37415000000 as a direct replacement for 38215000000?

A: Yes, both parts are parametric equivalents meeting all core electrical and mechanical specifications. However, verify that your application's certification requirements accept the alternative approval agencies listed for each part. The 37215000001 has lower breaking capacity (50 A vs. 100 A) and different certifications (no CQC or KC). The 37415000000 has significantly lower melting I²t (59 vs. 121.25) and is certified only by CSA and cULus.

Q: What is the difference between the SCHURTER 0034.6982 and the Littelfuse options?

A: The SCHURTER part meets all electrical specifications but has a physical height of 0.335" (8.50mm) compared to 0.315" (8.00mm) for Littelfuse parts. This 0.020" (0.50mm) difference may affect board layout or clearance in space-constrained applications. The SCHURTER part also has higher melting I²t (155) and different certifications (cURus and PSE/JET only).

Q: Are all these parts RoHS compliant?

A: Yes, all four parts are ROHS3 compliant and REACH unaffected.

Q: Which part should I choose for international applications?

A: The Littelfuse 38215000000 offers the broadest certification coverage (CQC, cURus, KC, PSE/JET, SEMKO, VDE) and is recommended for applications requiring multi-region compliance. For specific regions, verify that the required certification is present in the approval agency list for your selected part.

Q: Can I substitute based on breaking capacity alone?

A: No. Breaking capacity is a secondary parameter. Substitution requires exact matching of current rating, voltage rating, mounting type, package style, response time, operating temperature range, and physical dimensions. Breaking capacity and melting I²t variations are acceptable when all primary parameters match.
