Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0662.200HXSL are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

Acceptable Variation Parameters:

• Breaking Capacity @ Rated Voltage: 35 A or higher
• Melting I²t: 0.024 or higher
• Physical dimensions: Minor variations acceptable within radial can form factor
• Approval Agencies: Equivalent certifications acceptable (CSA, SEMKO, UL, VDE, CCC, cURus)

All identified substitutes meet or exceed the electrical performance requirements of the original part while maintaining mechanical compatibility with existing PCB layouts designed for radial through-hole fuses.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Littelfuse TR5® 370 Series):

Parts 37002000410 and 37002000000 are active production components from Littelfuse Inc. that provide direct electrical equivalence to the obsolete 0662.200HXSL. Both parts feature improved breaking capacity (50 A versus 35 A) and higher melting I²t values (0.03 versus 0.024), offering enhanced performance margins. The TR5® 370 series carries expanded approval certifications (CCC, cURus, SEMKO, VDE) and operates across the temperature range -40°C to 85°C. Physical dimensions show minor height reduction (8.00 mm versus 8.45 mm), which remains compatible with standard radial fuse footprints. The primary distinction between these two parts is packaging: 37002000410 is supplied in bulk packaging, while 37002000000 is supplied in cut tape format.

Secondary Substitute (SCHURTER MSF 250 Series):

Part 0034.6007 from SCHURTER Inc. provides electrical equivalence with identical current, voltage, and response characteristics. This part maintains the original breaking capacity (35 A) and melting I²t value (0.024), matching the performance envelope of the 0662.200HXSL. Physical dimensions are nearly identical (8.50 mm x 8.50 mm), ensuring direct mechanical compatibility. The MSF 250 series carries CCC, cURus, and VDE certifications with operating temperature range -40°C to 85°C. This option is suitable for applications where performance parity with the original specification is required.

Frequently Asked Questions (FAQ)

Q: Can 37002000410 or 37002000000 be used as direct replacements for 0662.200HXSL?

A: Yes. Both parts meet all critical electrical parameters: 200 mA current rating, 250 V AC voltage rating, fast-blow response, through-hole radial mounting, and board mount fuse type. The improved breaking capacity (50 A) and melting I²t (0.03) provide enhanced performance margins. Minor height reduction (0.315" versus 0.333") is compatible with standard radial fuse PCB layouts.

Q: What is the difference between 37002000410 and 37002000000?

A: Both parts are electrically and mechanically identical TR5® 370 series fuses. The sole difference is packaging: 37002000410 is supplied in bulk packaging, while 37002000000 is supplied in cut tape format. Selection depends on procurement and assembly requirements.

Q: Is the SCHURTER 0034.6007 equivalent to the Littelfuse options?

A: Yes, 0034.6007 provides full electrical equivalence with identical current, voltage, response time, and breaking capacity specifications. Physical dimensions are compatible with radial fuse footprints. Selection between Littelfuse and SCHURTER options depends on supply chain availability, certification requirements, and established vendor relationships.

Q: Are there any physical compatibility concerns with these substitutes?

A: All substitute parts maintain the 0.335" diameter radial can form factor. Height variations (0.315" to 0.335") are within acceptable tolerances for standard radial fuse footprints. Verify PCB layout clearances if height-constrained applications are present.

Q: Do all substitute parts carry the same certifications as the original?

A: Substitute parts carry equivalent or expanded certifications. The original 0662.200HXSL carries CSA, SEMKO, UL, and VDE approvals. Littelfuse TR5® 370 parts add CCC and cURus certifications. SCHURTER 0034.6007 carries CCC, cURus, and VDE certifications. All parts are ROHS3 compliant.

Q: What is the inventory status for these substitute parts?

A: All substitute parts are in active production with current stock availability: 37002000410 (1134 pcs), 37002000000 (866 pcs), and 0034.6007 (1235 pcs).
