Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5TT 160-R is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 160 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package Dimensions: 5mm x 20mm (exact match required)
• Mounting Configuration: Requires Holder (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The 0218.160HXP manufactured by Littelfuse Inc. meets all substitution criteria for the 5TT 160-R across these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The 0218.160HXP is a direct functional equivalent to the 5TT 160-R. Both components share identical electrical ratings, response characteristics, and mechanical form factors. The 0218.160HXP carries active product status from Littelfuse Inc., whereas the 5TT 160-R is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The 0218.160HXP is available in bulk packaging with higher inventory levels (1192 Pcs) compared to the 5TT 160-R (870 Pcs). The 0218.160HXP holds broader approval agency certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE, whereas the 5TT 160-R holds CE, CSA, and cULus certifications.

Frequently Asked Questions (FAQ)

Q: Can the 0218.160HXP replace the 5TT 160-R in existing applications?

A: Yes. Both components are 160 mA, 250 V AC/DC slow-blow glass cartridge fuses in 5mm x 20mm packages. Electrical and mechanical specifications are equivalent, and both require compatible fuse holders.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 5TT 160-R measures 0.201" diameter x 0.787" length (5.10mm x 20.00mm), while the 0218.160HXP measures 0.205" diameter x 0.787" length (5.20mm x 20.00mm). Both fit standard 5mm x 20mm fuse holders.

Q: What is the difference in breaking capacity between these parts?

A: The 5TT 160-R has a breaking capacity of 100A at rated voltage, while the 0218.160HXP has a breaking capacity of 35A at rated voltage. Breaking capacity differences do not affect substitution eligibility when both parts meet the application's circuit protection requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected. The 0218.160HXP holds additional certifications (CCC, K-MARK, SEMKO, UL, VDE) beyond those of the 5TT 160-R (CE, CSA, cULus).

Q: Why is the 5TT 160-R listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bel Fuse Inc. The 0218.160HXP from Littelfuse Inc. remains in active production and serves as the recommended equivalent for new designs and replacements.
