Substitute Part Grouping Explanation

Substitute parts for the 5STP 1.6-R are classified based on the following substitution criteria:

Parametric Equivalents (5ETP 1.6-R, 5TTP 1.6-R): Parts from the same manufacturer (Bel Fuse Inc.) with identical current rating (1.6 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), and package dimensions (5mm x 20mm axial). These parts differ in breaking capacity and melting I²t values but maintain full electrical and mechanical compatibility.

Direct Manufacturer Equivalents (0034.3119.PT, 0034.3119.TR, BK/S506-V-1.6-R): Parts from alternative manufacturers (SCHURTER Inc., Eaton - Electronics Division) meeting identical electrical specifications (1.6 A, 250 V AC, slow blow, cartridge glass) and mechanical package requirements (5mm x 20mm through-hole). Packaging format varies (bulk vs. cut tape).

Similar Equivalents (021801.6MXEP): Part from Littelfuse Inc. with matching electrical ratings (1.6 A, 250 V AC, slow blow, cartridge glass) and compatible package dimensions within tolerance (5.80mm x 22.50mm vs. 5.50mm x 21.00mm nominal).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are ROHS3 compliant. Selection among equivalents should be based on the following criteria:

Bel Fuse Inc. Series (5ETP 1.6-R, 5TTP 1.6-R): Recommended when maintaining the same manufacturer is preferred. The 5ETP 1.6-R offers the highest breaking capacity (150 A) and melting I²t (62), suitable for applications requiring enhanced fault tolerance. The 5TTP 1.6-R provides intermediate performance (100 A breaking capacity, 19.7 melting I²t) with reduced certification scope (CE, CSA, cULus, PSE).

SCHURTER Inc. Series (0034.3119.PT, 0034.3119.TR): Direct equivalents with identical breaking capacity (35 A) and melting I²t (10.5) to the main part. The 0034.3119.TR is supplied in cut tape packaging; 0034.3119.PT is supplied in bulk. Certification limited to cURus.

Eaton - Electronics Division (BK/S506-V-1.6-R): Offers comprehensive certification coverage (BSI, CCC, CSA, CURUS, IMQ, PSE/JET, SEMKO, VDE) with melting I²t of 21.7. Suitable for applications requiring broad international compliance.

Littelfuse Inc. (021801.6MXEP): Provides the broadest certification scope including K-MARK and UL. Melting I²t of 23.35 and lowest DC cold resistance (0.0336 Ohms) support applications with stringent performance requirements.

Frequently Asked Questions (FAQ)

Q: Can 5ETP 1.6-R replace 5STP 1.6-R directly?

A: Yes. Both parts share identical current rating (1.6 A), voltage rating (250 V AC), response time (slow blow), and package dimensions (5mm x 20mm axial). The 5ETP 1.6-R has higher breaking capacity (150 A vs. 35 A) and melting I²t (62 vs. 6.9), which does not prevent substitution but indicates enhanced fault tolerance capability.

Q: What is the difference between 0034.3119.PT and 0034.3119.TR?

A: Both parts are electrically and mechanically identical. The difference is packaging format: 0034.3119.PT is supplied in bulk; 0034.3119.TR is supplied in cut tape (CT). Selection depends on procurement and assembly requirements.

Q: Are dimensional variations between substitute parts significant?

A: Nominal dimensions vary slightly (e.g., 021801.6MXEP at 5.80mm x 22.50mm vs. 5.50mm x 21.00mm for 5STP 1.6-R). All parts are specified for 5mm x 20mm package class and are mechanically compatible with standard through-hole fuse holders designed for this package.

Q: Which substitute part has the broadest certification coverage?

A: The 021801.6MXEP (Littelfuse Inc.) carries the most comprehensive approvals: CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE. The BK/S506-V-1.6-R (Eaton) also provides extensive coverage including BSI and IMQ.

Q: Does melting I²t variation affect substitution compatibility?

A: Melting I²t indicates thermal response characteristics. Variations among listed parts (6.9 to 62) reflect different thermal designs but do not prevent electrical substitution. Selection should consider circuit protection requirements; higher melting I²t values provide greater tolerance to transient overcurrents.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component applications.
