Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSB2 is determined by the following electrical and mechanical parameters:

• Fuse Type: Cartridge, Glass construction
• Current Rating: 2 A
• Voltage Rating: 250 V AC
• Response Time: Fast Blow
• Package / Case: 5mm x 20mm
• Mounting Type: Requires Holder

All substitute parts listed below meet these core parameters and are therefore electrically and mechanically compatible with applications originally specified for the GSB2.

Selection among these substitutes should be based on inventory availability and packaging requirements:

• 0217002.MXP offers the highest inventory level at 30200 pieces, providing optimal supply chain continuity.
• 0217002.HXP provides 3823 pieces in stock with equivalent electrical specifications.
• 0217002.TXP is available with 775 pieces and maintains identical electrical and mechanical parameters.

All three parts are approved by BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE certification bodies, ensuring compliance with international safety and performance standards.

Frequently Asked Questions (FAQ)

Q: Are the Littelfuse 0217002 series parts direct replacements for the GSB2?

A: Yes. The 0217002.HXP, 0217002.MXP, and 0217002.TXP are electrically and mechanically equivalent to the GSB2. All parts share identical current rating (2 A), voltage rating (250 V AC), response time (Fast Blow), and physical dimensions (5mm x 20mm).

Q: What is the difference between 0217002.HXP, 0217002.MXP, and 0217002.TXP?

A: These three part numbers are functionally identical in electrical and mechanical specifications. The differences are limited to packaging format (all Bulk) and inventory availability. Selection should be based on procurement lead time and supply requirements.

Q: Do these substitute parts require the same holder as the GSB2?

A: All substitute parts require a holder for installation. Ensure that the existing holder is compatible with the 5mm x 20mm cartridge form factor.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three Littelfuse substitute parts (0217002.HXP, 0217002.MXP, 0217002.TXP) are ROHS3 compliant, matching the regulatory status of the GSB2.

Q: What certifications do the substitute parts carry?

A: All substitute parts are approved by BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE, providing comprehensive international safety and performance certification coverage.
