Engineering Selection Recommendations

Primary Part: BK/GMA-V-800-R (Eaton - Electronics Division)

The BK/GMA-V-800-R is the specified component with active product status and current manufacturing support. It carries CSA, PSE, and UL approvals. This part is suitable for applications requiring Eaton component qualification or existing supply chain integration.

Substitute Part: 0217.800MXEP (Littelfuse Inc.)

The 0217.800MXEP is a direct electrical and mechanical equivalent with active product status. It carries expanded regulatory approvals including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE certifications, plus REACH compliance documentation. The substitute part offers higher inventory availability (2900 units versus 705 units) and extended operating temperature range (-55°C ~ 125°C). Both parts are RoHS compliant and share identical critical electrical parameters.

Selection between these parts depends on supply availability, existing manufacturer qualification requirements, and regulatory certification scope for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 0217.800MXEP replace the BK/GMA-V-800-R in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical current rating (800 mA), voltage rating (250 V AC), fuse type (cartridge glass), package dimensions (5mm x 20mm axial), response time (fast blow), and breaking capacity (35 A). Both are active products with current manufacturing support.

Q: Are there differences in physical dimensions between these parts?

A: Minor dimensional variations exist. The BK/GMA-V-800-R measures 0.218" Dia x 0.831" L (5.54mm x 21.10mm). The 0217.800MXEP measures 0.228" Dia x 0.886" L (5.80mm x 22.50mm). Both fit the 5mm x 20mm axial package specification and are compatible with standard through-hole mounting.

Q: What are the differences in electrical characteristics?

A: The melting I²t value differs slightly (0.7 for Eaton versus 0.85 for Littelfuse) and DC cold resistance differs (0.17 Ohms versus 0.1203 Ohms). These variations remain within acceptable tolerance ranges for fast-blow fuse cartridges and do not affect functional equivalence at the specified 800 mA, 250 V rating.

Q: Which part has better regulatory coverage?

A: The 0217.800MXEP carries broader regulatory approvals (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) compared to the BK/GMA-V-800-R (CSA, PSE, UL). The Littelfuse part also includes REACH compliance documentation. Selection depends on target market and regulatory requirements.

Q: Is inventory availability a factor in part selection?

A: Yes. The 0217.800MXEP has 2900 units in stock compared to 705 units for the BK/GMA-V-800-R. For applications with high-volume requirements or extended lead time considerations, the Littelfuse substitute offers greater availability.

Q: Are both parts RoHS compliant?

A: Yes. The BK/GMA-V-800-R is RoHS Compliant. The 0217.800MXEP is ROHS3 Compliant. Both meet RoHS requirements for the specified application.
