Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RGEF600-2 is determined by the following critical parameters:

• Voltage - Max: 16V (exact match required)
• Current - Hold (Ih) (Max): 6 A (exact match required)
• Current - Trip (It): 10.2 A (exact match required)
• Type: Polymeric (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Disc (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

The identified substitute part 0ZRA0600FF2D from Bel Fuse Inc. meets all critical electrical and mechanical parameters. Differences in packaging format (Tape & Reel versus Cut Tape) and minor variations in physical dimensions and resistance characteristics do not affect functional equivalence for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the RGEF600-2 and 0ZRA0600FF2D are active production components with ROHS3 compliance. The RGEF600-2 carries CSA, TUV, and UL approvals, while the 0ZRA0600FF2D carries cURus and TUV approvals with AEC-Q200 automotive qualification. Selection between these parts should be based on specific application compliance requirements and packaging format availability. The RGEF600-2 is suitable for general industrial applications requiring UL certification. The 0ZRA0600FF2D is appropriate for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can the 0ZRA0600FF2D replace the RGEF600-2 in my circuit?

A: Yes, the 0ZRA0600FF2D meets all critical electrical parameters: 16V maximum voltage, 6A hold current, and 10.2A trip current. Both components are polymeric PTC resettable fuses with identical mounting type and package configuration. Verify that your application's compliance requirements align with the available certifications for each part.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer, packaging format (Cut Tape versus Tape & Reel), physical dimensions (minor variations), resistance characteristics, trip time (3.3s versus 5.8s), and approval agencies. All critical electrical ratings are identical.

Q: Does the difference in trip time affect substitution?

A: Both parts have identical trip current (10.2A) and hold current (6A) specifications. The difference in time to trip (3.3s versus 5.8s) reflects different thermal response characteristics but does not affect functional equivalence for standard overcurrent protection applications.

Q: Which part should I use for automotive applications?

A: The 0ZRA0600FF2D includes AEC-Q200 automotive qualification and cURus certification, making it suitable for automotive applications. The RGEF600-2 is qualified for general industrial use with UL, CSA, and TUV approvals.

Q: Are there packaging considerations for these parts?

A: The RGEF600-2 is supplied in Cut Tape (CT) packaging, while the 0ZRA0600FF2D is supplied in Tape & Reel (TR) packaging. Select based on your assembly process requirements and volume needs.
