Substitute Part Grouping Explanation

The NDNFD1-WH has one identified equivalent substitute: NDNLFD1-WH. This substitution is valid based on the following critical parameters that must remain constant for functional equivalence:

• Voltage rating: 600V
• Current rating: 15 A
• Fuse type: Cartridge
• Fuse size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Number of circuits: 1
• Mounting type: DIN Rail
• Fuseholder type: Block
• Compatible fuse standard: 3AG, 1/4" x 1-1/4" (SFE-20)

The NDNLFD1-WH maintains identical electrical and mechanical specifications, ensuring direct compatibility in applications currently using the NDNFD1-WH.

Parameter Comparison

Engineering Selection Recommendations

The NDNLFD1-WH is the direct equivalent substitute for the obsolete NDNFD1-WH. Selection of the NDNLFD1-WH is supported by:

• Identical electrical specifications (600V, 15A, single-circuit cartridge configuration)
• Identical mechanical specifications (fuse size, DIN rail mounting, block fuseholder type)
• Identical fuse compatibility standard (3AG, 1/4" x 1-1/4")
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance certification on the substitute part
• Matching export classification (EAR99) and tariff codes (8536.69.8000)

The NDNLFD1-WH provides a direct replacement path for legacy NDNFD1-WH installations without requiring circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can NDNLFD1-WH be used as a direct replacement for NDNFD1-WH?

A: Yes. Both parts share identical voltage rating (600V), current rating (15A), fuse size (0.25" Dia x 1.26" L), mounting type (DIN Rail), and compatible fuse standard (3AG, 1/4" x 1-1/4"). No circuit or mechanical modifications are required.

Q: What is the primary difference between these two parts?

A: The NDNFD1-WH is obsolete, while the NDNLFD1-WH is active. The NDNLFD1-WH also carries RoHS compliance certification. All functional and mechanical parameters remain identical.

Q: Are there any compatibility concerns when substituting NDNLFD1-WH for NDNFD1-WH?

A: No compatibility concerns exist. Both parts are manufactured by Eaton - Bussmann Electrical Division within the Magnum® series and maintain identical specifications for electrical performance, mechanical fit, and fuse accommodation.

Q: What fuse types are compatible with these fuse blocks?

A: Both the NDNFD1-WH and NDNLFD1-WH accept 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20 standard).

Q: Is the NDNLFD1-WH available in stock?

A: Availability varies by distributor. The NDNLFD1-WH maintains active product status, ensuring it remains in the manufacturer's production line and is generally available through authorized distributors.
