Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP1302-001LF is determined by matching the following critical electrical and mechanical parameters:

• Diode Type: PIN - Single configuration
• Voltage - Peak Reverse (Max): 200V minimum rating
• Capacitance @ Vr, F: 0.3pF @ 30V, 1MHz
• Resistance @ If, F: 1.5Ohm @ 100mA, 100MHz
• Power Dissipation (Max): 250 mW
• Operating Temperature Range: -65°C ~ 150°C (TA)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SMP1302-040LF qualifies as a direct electrical substitute, sharing identical electrical specifications and compliance certifications. The primary difference is the package format: SOD-882 versus SOT-23-3, which affects board layout and assembly considerations but not electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The SMP1302-040LF is the active equivalent for the obsolete SMP1302-001LF. Both parts share identical electrical specifications, voltage ratings, capacitance, resistance characteristics, power dissipation, and operating temperature ranges. Both maintain ROHS3 compliance and MSL 1 rating.

Selection between these parts depends on package compatibility with existing board layouts. The SMP1302-001LF uses SOT-23-3 packaging, while the SMP1302-040LF uses SOD-882 packaging. PCB footprint and assembly process requirements will determine which package is appropriate for your application.

The SMP1302-040LF is recommended for new designs and ongoing procurement due to its active product status and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the SMP1302-040LF directly replace the SMP1302-001LF in existing designs?

A: Electrical substitution is direct. The SMP1302-040LF matches all electrical parameters, voltage ratings, and thermal specifications. However, the package change from SOT-23-3 to SOD-882 requires PCB layout modification and assembly process adjustment.

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

A: The SMP1302-001LF and SMP1302-040LF are electrically identical PIN diodes with matching 200V ratings, 250 mW power dissipation, and -65°C to 150°C operating range. The difference is packaging: SOT-23-3 versus SOD-882. The SMP1302-040LF is the active product.

Q: Are both parts RoHS compliant?

A: Yes. Both the SMP1302-001LF and SMP1302-040LF are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the SMP1302-001LF listed as obsolete?

A: The SMP1302-001LF has been discontinued by Skyworks Solutions Inc. The SMP1302-040LF in SOD-882 packaging is the active replacement, offering the same electrical performance in a different package format.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching Diode Type (PIN - Single), Voltage - Peak Reverse (200V), Capacitance (0.3pF @ 30V, 1MHz), Resistance (1.5Ohm @ 100mA, 100MHz), Power Dissipation (250 mW), Operating Temperature (-65°C ~ 150°C), and compliance certifications (ROHS3, MSL 1).
