MF-RHT050-2-17 Equivalent & Substitute Parts

Part Overview

The Bourns MF-RHT050-2-17 is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. This through-hole radial component operates at a maximum voltage of 30V with a hold current of 500 mA and a trip current of 920 mA. The device is part of the Multifuse® MF-RHT series and maintains active product status. Substitute parts are identified to address packaging availability and supply chain requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF-RHT050-2-17 are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is the match of all critical electrical parameters: maximum voltage rating (30V), hold current (500 mA), trip current (920 mA), maximum current (40 A), time to trip (2.5 s), initial resistance (480 mOhms minimum), and post-trip resistance (1.1 Ohms maximum). Mechanical compatibility is ensured through identical package type (Radial, Disc), mounting method (Through Hole), physical dimensions (0.291" Dia x 0.118" T), and lead spacing (0.201"). Operating temperature range (-40°C ~ 125°C), product type (Polymeric), and series designation (Multifuse® MF-RHT) must also align. The substitute part MF-RHT050-2 differs only in packaging format (Cut Tape versus Tape & Reel), which does not affect electrical or mechanical performance in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The MF-RHT050-2 serves as a direct parametric equivalent to the MF-RHT050-2-17. Both components maintain active product status from Bourns Inc. and carry identical electrical specifications, mechanical dimensions, and compliance certifications. The MF-RHT050-2-17 is supplied in Tape & Reel packaging, while the MF-RHT050-2 is supplied in Cut Tape format. This packaging difference does not affect circuit performance, electrical characteristics, or mechanical fit. Both parts are AEC-Q200 rated, ROHS3 compliant, and carry identical approval agency certifications where applicable. Selection between these parts should be based on assembly process requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can MF-RHT050-2 replace MF-RHT050-2-17 in my circuit?

A: Yes. The MF-RHT050-2 is a parametric equivalent with identical electrical and mechanical specifications. The only difference is the packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance or component functionality.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths. Both formats contain the same component with identical specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the MF-RHT050-2-17 and MF-RHT050-2 have identical physical dimensions of 0.291" Dia x 0.118" T (7.40mm x 3.00mm) with a lead spacing of 0.201" (5.10mm). They are mechanically interchangeable in through-hole applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, carry AEC-Q200 ratings, and have identical moisture sensitivity levels (MSL 1 - Unlimited). The MF-RHT050-2-17 lists specific approval agencies (cUL, cURus, TUV), while the MF-RHT050-2 does not specify approval agencies in the provided data.

Q: What electrical parameters must match for substitution?

A: Critical matching parameters include maximum voltage (30V), hold current (500 mA), trip current (920 mA), maximum current (40 A), time to trip (2.5 s), initial resistance (480 mOhms minimum), and post-trip resistance (1.1 Ohms maximum). Both parts match all these specifications.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your assembly process can accommodate the packaging format. If your equipment requires Tape & Reel format, use MF-RHT050-2-17. If your process uses Cut Tape format, use MF-RHT050-2. The electrical and mechanical performance in the circuit is identical.
