Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS2PH9HM3/84A are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 µA @ 90 V
• Capacitance @ Vr, F: 65 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-220AA (SMP)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C ~ 175°C

Compliance Parameters (Must Match Exactly):

• Technology: Schottky
• Series: eSMP®
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts identified below maintain identical electrical performance and mechanical compatibility. Packaging format variations (Cut Tape, Digi-Reel®, or Tape & Reel) do not affect functional equivalence and represent procurement format options only.

Parameter Comparison

Engineering Selection Recommendations

SS2PH9-M3/84A is the primary substitute for SS2PH9HM3/84A. This part maintains active product status with Vishay General Semiconductor - Diodes Division and is available in Cut Tape (CT) and Digi-Reel® packaging formats. All electrical parameters, mechanical specifications, and compliance certifications are identical to the main part. This substitute provides direct functional replacement with improved supply chain availability.

SS2PH9-M3/85A is an alternative substitute for SS2PH9HM3/84A. This part maintains active product status and is available in Tape & Reel (TR) packaging format. All electrical parameters, mechanical specifications, and compliance certifications are identical to the main part. This substitute is suitable for high-volume production environments requiring reel-based component delivery.

Both substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, matching the compliance profile of the obsolete main part. Selection between SS2PH9-M3/84A and SS2PH9-M3/85A depends on procurement packaging requirements and supply chain logistics rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can SS2PH9-M3/84A or SS2PH9-M3/85A be used as direct replacements for SS2PH9HM3/84A?

A: Yes. Both substitute parts are parametrically equivalent across all electrical and mechanical specifications. They share identical voltage ratings (90V), current ratings (2A), forward voltage characteristics (800mV @ 2A), switching speed (Fast Recovery ≤ 500ns), leakage current (1µA @ 90V), and package format (DO-220AA SMP). Direct substitution is supported without circuit modification.

Q: What is the difference between SS2PH9-M3/84A and SS2PH9-M3/85A?

A: The primary difference is packaging format. SS2PH9-M3/84A is supplied in Cut Tape (CT) and Digi-Reel® formats, while SS2PH9-M3/85A is supplied in Tape & Reel (TR) format. All electrical parameters and mechanical specifications are identical. Selection depends on production assembly equipment compatibility and procurement volume requirements.

Q: Are the substitute parts compatible with existing PCB designs for SS2PH9HM3/84A?

A: Yes. Both substitute parts use the identical DO-220AA (SMP) surface mount package with matching pin configuration, footprint, and thermal characteristics. PCB layout and assembly processes require no modification.

Q: What is the product status difference between the main part and substitutes?

A: SS2PH9HM3/84A is classified as obsolete, indicating discontinued production and limited availability. SS2PH9-M3/84A and SS2PH9-M3/85A are active products with ongoing production and established supply chains. Substitution is necessary to ensure component availability for new production runs and long-term supply security.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both SS2PH9-M3/84A and SS2PH9-M3/85A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) classification, matching the compliance profile of SS2PH9HM3/84A. No compliance-related design changes are required.

Q: Are there any thermal or electrical performance differences between the three parts?

A: No. All three parts share identical operating temperature range (-55°C to 175°C), forward voltage characteristics (800mV @ 2A), reverse leakage current (1µA @ 90V), junction capacitance (65pF @ 4V, 1MHz), and fast recovery switching speed (≤ 500ns). Thermal and electrical performance are equivalent.
