Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0215010.MRET2P is determined by strict alignment of the following parameters:

  • Current Rating: 10 A (exact match required)
  • Voltage Rating (AC): 250 V (exact match required)
  • Fuse Type: Cartridge, Ceramic (exact match required)
  • Response Time: Slow Blow (exact match required)
  • Package / Case: 5mm x 20mm (Axial) (exact match required)
  • Mounting Type: Through Hole (exact match required)
  • Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)
  • Operating Temperature Range: -55°C ~ 125°C (exact match required)

The Conquer TUC UDA-P 10A 250V (PF) meets all substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

Both the Littelfuse 0215010.MRET2P and Conquer TUC UDA-P 10A 250V (PF) are Active products with full RoHS3 compliance and REACH Unaffected status. The Littelfuse part carries approvals from BSI, CE, CSA, KC, METI, SEMKO, UL, and VDE. The Conquer substitute carries approvals from CCC, cURus, KC, PSE, and TUV. Selection between these parts should be based on certification requirements specific to the end application and regional regulatory compliance needs. Both parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the Conquer TUC UDA-P 10A 250V (PF) be used as a direct replacement for the Littelfuse 0215010.MRET2P?

A: Yes. Both parts share identical electrical ratings (10A, 250VAC), fuse type (Cartridge, Ceramic), response time (Slow Blow), mechanical dimensions (5mm x 20mm), and operating temperature range (-55°C ~ 125°C). Both are ROHS3 compliant and REACH Unaffected.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity, packaging format (Littelfuse supplied in Tape & Reel; Conquer supplied in Bulk), and regional safety certifications. DC Cold Resistance and Melting I²t values show minor variations within acceptable engineering tolerances.

Q: Are the safety certifications equivalent?

A: Both parts hold active safety certifications appropriate to their respective manufacturers and markets. The Littelfuse part includes UL and VDE certifications; the Conquer part includes CCC and PSE certifications. Application-specific certification requirements should determine final selection.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Bulk packaging formats do not affect the electrical or mechanical performance of the fuse itself. Packaging selection is based on production handling and assembly requirements.

Q: Are these parts suitable for both AC and DC applications?

A: The voltage rating specified (250VAC) applies to AC applications. DC application suitability must be determined by the end-use circuit design and is not addressed by the AC voltage rating alone.
