Key Parameters

Substitute Part Grouping Explanation

The 5TTP 6-R qualifies as a direct substitute for the 5TTP 6 based on identical electrical and mechanical parameters. Both parts share the same current rating (6A), voltage rating (125VAC), fuse type (ceramic cartridge), response characteristic (slow blow), physical dimensions (5mm x 20mm), mounting configuration (through hole), breaking capacity (10kA), thermal operating range (-55°C to 125°C), and DC cold resistance (0.015 Ohms). The substitution is valid across all critical performance specifications that determine functional compatibility in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The 5TTP 6-R is the appropriate selection for applications currently using the obsolete 5TTP 6. Both parts maintain identical electrical performance and physical compatibility. The 5TTP 6-R offers the additional advantage of active product status, ensuring ongoing availability and supply chain reliability. The 5TTP 6-R also achieves ROHS3 compliance, whereas the original 5TTP 6 does not, making it suitable for applications subject to RoHS regulatory requirements. All regulatory certifications (CE, CSA, PSE) are maintained across both variants.

Frequently Asked Questions (FAQ)

Q: Can the 5TTP 6-R be used as a direct replacement for the 5TTP 6?

A: Yes. Both parts are identical in current rating (6A), voltage rating (125VAC), fuse type (ceramic cartridge), response time (slow blow), physical dimensions (5mm x 20mm), and all electrical performance parameters. Direct substitution is valid without circuit modification.

Q: What is the difference between the 5TTP 6 and 5TTP 6-R?

A: The primary differences are product status and RoHS compliance. The 5TTP 6 is obsolete and RoHS non-compliant, while the 5TTP 6-R is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 5TTP 6-R is supplied in bulk packaging, whereas the original 5TTP 6 packaging specification is not detailed. Both maintain the same 5mm x 20mm axial form factor and through-hole mounting configuration.

Q: Does the 5TTP 6-R maintain all regulatory certifications?

A: Yes. The 5TTP 6-R retains all approval agencies: CE, CSA, and PSE certifications identical to the original 5TTP 6.

Q: Is the 5TTP 6-R suitable for new designs?

A: Yes. The 5TTP 6-R is an active product with current manufacturing status, making it appropriate for both new designs and field replacements of obsolete 5TTP 6 units.
