Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5TT 700-R is determined by strict equivalence across the following critical parameters: current rating (700 mA), voltage rating (250 V AC), response time (slow blow), package dimensions (5mm x 20mm), fuse type (cartridge glass), and mounting requirement (holder-based installation). All identified substitute parts meet these core electrical and mechanical criteria, ensuring functional interchangeability within the specified application envelope. Operating temperature range (-55°C ~ 125°C) and RoHS3 compliance are maintained across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three fuse options maintain active product status and ROHS3 compliance. The 5TT 700-R from Bel Fuse Inc. carries cULus certification, while the Littelfuse alternatives (0239.700MXP and 0239.700HXP) carry UL and KC certifications in addition to CE and CSA. Selection between these parts should be based on certification requirements specific to the target application and regional regulatory requirements. The Littelfuse 0239.700MXP and 0239.700HXP are electrically and mechanically equivalent alternatives with identical electrical characteristics within the slow-blow fuse category.

Frequently Asked Questions (FAQ)

Q: Can 0239.700MXP and 0239.700HXP be used interchangeably with 5TT 700-R?

A: Yes. All three parts share identical current rating (700 mA), voltage rating (250 V AC), response time (slow blow), and package dimensions (5mm x 20mm). They are functionally equivalent for circuit protection applications requiring these specifications.

Q: What is the difference between the Littelfuse 0239.700MXP and 0239.700HXP?

A: Both parts are electrically and mechanically identical. They share the same current rating, voltage rating, response time, package dimensions, breaking capacity, melting I²t, DC cold resistance, and approval certifications. Selection between them is based on inventory availability.

Q: Are there differences in breaking capacity between the main part and substitutes?

A: Yes. The 5TT 700-R has a breaking capacity of 100A at rated voltage, while both Littelfuse alternatives have a breaking capacity of 35A. This difference should be evaluated against application requirements.

Q: Do all parts require a holder for installation?

A: Yes. All three fuse options are cartridge-type glass fuses in 5mm x 20mm format and require a compatible holder for installation.

Q: What certifications apply to each part?

A: The 5TT 700-R carries CE, CSA, and cULus approvals. The Littelfuse 0239.700MXP and 0239.700HXP carry CE, CSA, KC, and UL approvals. Application requirements should determine which certification set is necessary.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.
