Substitute Part Grouping Explanation

Substitution of the obsolete SS2P2-E3/85A is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 20 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 550 mV @ 2 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 150 µA @ 20 V
Package / Case: DO-220AA (SMP)
Operating Temperature - Junction: -55°C ~ 150°C
RoHS Status: ROHS3 Compliant

All identified substitute parts maintain identical electrical performance specifications and package configuration. Differences exist only in product status (active vs. obsolete), packaging format (Tape & Reel vs. Cut Tape), and optional automotive qualification grades.

Engineering Selection Recommendations

For Standard Industrial Applications: Select SS2P2-M3/85A or SS2P2-M3/84A. Both parts are active products with identical electrical specifications to the obsolete SS2P2-E3/85A. SS2P2-M3/85A is supplied in Tape & Reel packaging; SS2P2-M3/84A is available in Cut Tape format. Selection between these two depends on production volume and assembly line requirements.

For Automotive Applications: Select SS2P2HM3/85A or SS2P2HM3/84A. These parts carry automotive-grade designation with AEC-Q101 qualification, meeting automotive industry reliability standards. Both maintain identical electrical performance and operating temperature range as the standard-grade alternatives. SS2P2HM3/85A is supplied in Tape & Reel; SS2P2HM3/84A is available in Cut Tape format.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing processes and long-term storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SS2P2-M3/85A directly replace SS2P2-E3/85A in existing designs?

A: Yes. Both parts share identical electrical specifications: 20V reverse voltage, 2A average rectified current, 550mV forward voltage at 2A, and fast recovery characteristics. The DO-220AA surface mount package is identical. The primary difference is product status: SS2P2-E3/85A is obsolete while SS2P2-M3/85A is active.

Q: What is the difference between SS2P2-M3/85A and SS2P2-M3/84A?

A: Electrical specifications are identical. The difference is packaging format: SS2P2-M3/85A is supplied in Tape & Reel (TR); SS2P2-M3/84A is supplied in Cut Tape (CT). Selection depends on assembly equipment and production volume requirements.

Q: Should I use automotive-grade parts (SS2P2HM3/85A or SS2P2HM3/84A) for non-automotive applications?

A: Automotive-grade parts are not required for standard industrial applications. However, they may be selected if enhanced reliability documentation or AEC-Q101 qualification is mandated by customer specifications or quality standards. Electrical performance is identical to standard-grade alternatives.

Q: Are there any differences in capacitance specifications between substitute parts?

A: SS2P2-M3/85A, SS2P2HM3/84A, and SS2P2HM3/85A specify capacitance at 110pF @ 4V, 1MHz. SS2P2-E3/85A and SS2P2-M3/84A do not provide capacitance specifications. This difference does not affect substitution eligibility for applications where capacitance is not a critical design parameter.

Q: What is the inventory status of these substitute parts?

A: SS2P2HM3/84A has the highest inventory (9300 pcs). SS2P2-M3/84A has 1548 pcs. SS2P2-M3/85A has 892 pcs. SS2P2HM3/85A has 1189 pcs. Inventory levels should be verified with the supplier for current availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts and the main part carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.
