Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMP1302-011LF is determined by electrical and thermal parameter equivalence within the RF Diode PIN - Single category. The following criteria establish valid substitution:

Electrical Equivalence Requirements:

• Diode Type: PIN - Single (identical functional classification)
• Voltage - Peak Reverse (Max): 200V (exact match)
• Capacitance @ Vr, F: 0.3pF @ 30V, 1MHz (exact match)
• Resistance @ If, F: 1.5Ohm @ 100mA, 100MHz (exact match)
• Power Dissipation (Max): 250 mW (exact match)
• Operating Temperature Range: -65°C ~ 150°C (TA) (exact match)

Mechanical and Compliance Considerations:

• Moisture Sensitivity Level: MSL 1 (Unlimited) - no restrictions
• Manufacturer: Skyworks Solutions Inc. (same manufacturer ensures design consistency)
• Product Status: Active (ensures ongoing support and availability)

The SMP1302-079LF qualifies as a direct electrical substitute, with the primary distinction being packaging format (SC-79 versus SOD-323) and supply method (Cut Tape & Digi-Reel® versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both the SMP1302-011LF and SMP1302-079LF maintain Active product status from Skyworks Solutions Inc., ensuring continued manufacturing support and supply availability. The electrical parameters are identical across all critical RF performance specifications: peak reverse voltage, junction capacitance, forward resistance, and power dissipation ratings.

The SMP1302-079LF carries explicit ROHS3 Compliance and REACH Unaffected certifications, with ECCN classification as EAR99 and HTSUS code 8541.10.0070. These compliance attributes are documented for the substitute part.

Selection between these parts should be based on:

1. Packaging Format Requirements: SOD-323 (SMP1302-011LF) versus SC-79 (SMP1302-079LF) package compatibility with PCB layout and assembly equipment
2. Supply Chain Format: Tape & Reel (TR) versus Cut Tape (CT) & Digi-Reel® based on production volume and handling infrastructure
3. Inventory Availability: Current stock levels (20,100 Pcs for SMP1302-011LF; 29,400 Pcs for SMP1302-079LF)
4. Compliance Documentation: Explicit RoHS3 compliance certification for SMP1302-079LF

Both parts are electrically interchangeable when package and supply format constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can SMP1302-079LF be used as a direct replacement for SMP1302-011LF in existing designs?

A: Electrical substitution is valid. The SMP1302-079LF matches all electrical parameters: 200V peak reverse voltage, 0.3pF capacitance, 1.5Ohm resistance, and 250 mW power dissipation. However, the package format differs (SC-79 versus SOD-323), requiring PCB layout verification and assembly process compatibility assessment.

Q: What is the primary difference between these two parts?

A: The SMP1302-011LF uses SOD-323 packaging in Tape & Reel format, while the SMP1302-079LF uses SC-79 packaging in Cut Tape & Digi-Reel® format. All electrical and thermal specifications are identical.

Q: Are there any compliance differences between the parts?

A: The SMP1302-079LF explicitly documents ROHS3 Compliance, REACH Unaffected status, and EAR99 ECCN classification. Compliance documentation for the SMP1302-011LF is not specified in the provided data.

Q: Which part should be selected for new production designs?

A: Selection depends on packaging format compatibility with your PCB design and assembly equipment. Both parts are electrically equivalent and maintain Active product status. Verify package footprint requirements (SOD-323 versus SC-79) before design implementation.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures, simplifying supply chain management and reducing storage costs.

Q: Are there inventory considerations for part selection?

A: The SMP1302-079LF has higher current inventory (29,400 Pcs) compared to the SMP1302-011LF (20,100 Pcs). For high-volume production, the substitute part may offer better supply availability.
