5STP 160-R Equivalent & Substitute Parts

Part Overview

The 5STP 160-R is a 160 mA, 250 V AC/DC slow-blow glass cartridge fuse in a 5mm x 20mm axial package manufactured by Bel Fuse Inc. This component is actively produced and widely used in electronic equipment requiring overcurrent protection. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling component interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5STP 160-R is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 160 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part 0034.3109.PT manufactured by SCHURTER Inc. meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 5STP 160-R and 0034.3109.PT are active products with ROHS3 compliance and REACH unaffected status. The 5STP 160-R carries approval from CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE agencies. The 0034.3109.PT carries cURus approval. Selection between these parts should be based on design certification requirements, supply chain availability, and approval agency alignment with the end application. Both components are suitable for through-hole PCB mounting in 5mm x 20mm fuse holder receptacles.

Frequently Asked Questions (FAQ)

Q: Can 0034.3109.PT be used as a direct replacement for 5STP 160-R?

A: Yes. Both parts share identical electrical ratings (160 mA, 250 V AC), fuse type (cartridge, glass), response time (slow blow), package dimensions (5mm x 20mm axial), and operating temperature range (-55°C ~ 125°C). Both are ROHS3 compliant and carry 35 A breaking capacity.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 5STP 160-R measures 0.217" diameter x 0.827" length (5.50mm x 21.00mm). The 0034.3109.PT measures 0.213" diameter x 0.886" length (5.40mm x 22.50mm). These variations remain within standard fuse holder tolerances for 5mm x 20mm axial packages.

Q: What approval agencies certify each part?

A: The 5STP 160-R is certified by CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE. The 0034.3109.PT is certified by cURus. Verify that the selected part's certifications align with your application's regulatory requirements.

Q: Are both parts currently in stock?

A: Yes. The 5STP 160-R has 1954 pieces in stock. The 0034.3109.PT has 4065 pieces in stock.

Q: What is the difference in melting I²t values?

A: The 5STP 160-R has a melting I²t of 0.08, while the 0034.3109.PT has a melting I²t of 0.23. Both values fall within acceptable ranges for 160 mA slow-blow fuses and do not affect interchangeability for standard overcurrent protection applications.
