Key Parameters

Substitute Part Grouping Explanation

Substitution for the SNZF220DFT1G is determined by strict equivalence across the following critical parameters:

• Filter technology and order: RC (Pi), 2nd order low-pass configuration
• Electrical specifications: 110 Ohms resistance and 22pF capacitance per channel
• Number of channels: 2-channel configuration
• Cutoff frequency: 220MHz
• Package type: 5-TSSOP, SC-70-5, SOT-353
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm), 0.043" height (1.09mm)
• ESD protection: Integrated protection required
• Compliance: RoHS3 and REACH standards

The NZF220DFT1G meets all these criteria and serves as a direct functional equivalent, with the primary difference being packaging format (Tape & Reel versus Cut Tape) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The NZF220DFT1G is the direct equivalent substitute for the obsolete SNZF220DFT1G. Both parts are manufactured by onsemi and share identical electrical and mechanical specifications. The NZF220DFT1G maintains active product status, ensuring long-term availability and supply chain continuity.

Selection between these parts is determined by packaging requirements: the SNZF220DFT1G is supplied in Cut Tape format, while the NZF220DFT1G is supplied in Tape & Reel format. Both comply with RoHS3 and REACH standards, making them suitable for regulated applications including automotive and mobile device data line filtering.

Frequently Asked Questions (FAQ)

Q: Can the NZF220DFT1G replace the SNZF220DFT1G in existing designs?

A: Yes. The NZF220DFT1G is electrically and mechanically identical to the SNZF220DFT1G. Both parts feature the same 110 Ohms resistance, 22pF capacitance, 2-channel configuration, 220MHz cutoff frequency, and 5-TSSOP package dimensions. The only difference is packaging format and product status.

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

A: Cut Tape (CT) packaging supplies individual components on tape segments, suitable for small-quantity orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly processes. Both formats contain identical components.

Q: Are there any compliance differences between these parts?

A: No. Both the SNZF220DFT1G and NZF220DFT1G are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements for automotive and mobile device applications.

Q: Why is the SNZF220DFT1G listed as obsolete?

A: The SNZF220DFT1G has been discontinued by onsemi. The NZF220DFT1G remains in active production and serves as the current equivalent part for new designs and ongoing production requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a height of 0.043" (1.09mm), ensuring identical PCB footprint and assembly compatibility.
