Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CE83A0350 is determined by the following critical parameters:

• Design Type: Hinged (Snap On) configuration for free-hanging installation
• Inner Diameter: Nominal range 0.213" to 0.228" (5.41mm to 5.80mm) to accommodate cable core sizes
• Mounting Method: Free Hanging installation without additional fixtures
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Impedance Range: Ferrite cores with impedance values suitable for EMI suppression applications

The substitute parts listed below maintain the core functional characteristics of hinged ferrite design and free-hanging mounting while offering variations in impedance, outer dimensions, and material composition to address different application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original CE83A0350 component.

SS28B2031 is an active product from Leader Tech Inc. with a 200Ohm impedance rating. The inner diameter of 0.228" (5.80mm) is compatible with the original specification tolerance range. The outer dimensions are larger at 1.256" W x 1.256" L (31.90mm x 31.90mm), and the length extends to 1.256" (31.90mm). This substitute is suitable for applications where the increased impedance and larger form factor are acceptable within the design envelope.

28A0434-0A2 is an active product from Laird-Signal Integrity Products with a 277Ohm impedance rating. The inner diameter of 0.214" (5.44mm) closely matches the original specification. The outer diameter of 0.579" (14.71mm) is smaller than the original, and the length extends to 1.694" (43.03mm). This substitute is suitable for applications where higher impedance and extended length are compatible with the installation space.

Frequently Asked Questions (FAQ)

Q: What determines if a ferrite core can substitute for the CE83A0350?

A: The primary substitution criteria are: hinged (snap-on) design for free-hanging installation, inner diameter within the 0.213" to 0.228" range to accommodate standard cable cores, ROHS3 compliance, and REACH unaffected status. Impedance values, outer dimensions, and length may vary based on application requirements.

Q: How do impedance differences affect substitution?

A: The CE83A0350 provides 110Ohm @ 100MHz. Substitute parts offer higher impedance values (200Ohm and 277Ohm @ 100MHz). Higher impedance ferrite cores provide greater EMI suppression but may alter the frequency response characteristics of the circuit. Selection depends on the specific EMI suppression requirements of the application.

Q: Are there packaging differences between the substitute parts?

A: Yes. The CE83A0350 is listed with dash packaging. SS28B2031 is supplied in bulk packaging, while 28A0434-0A2 is supplied in tray packaging. Packaging selection may affect procurement quantities and handling procedures.

Q: Can the substitute parts be used interchangeably in existing designs?

A: Mechanical compatibility must be verified. The inner diameter tolerance range (0.213" to 0.228") accommodates standard cable core sizes. However, outer dimension and length variations must be confirmed against the available installation space. The impedance change will alter EMI suppression characteristics and must be evaluated for the specific application.

Q: What is the inventory status of these parts?

A: CE83A0350 has 1040 pieces in stock but is obsolete. SS28B2031 has 795 pieces in stock and is active. 28A0434-0A2 has 34902 pieces in stock and is active. Active products are recommended for new designs and long-term availability.
