MA2S11100L Equivalent & Substitute Parts

Part Overview

The MA2S11100L is a general-purpose rectifier diode manufactured by Panasonic Electronic Components, rated for 80V DC reverse voltage and 100mA average rectified current in a surface mount SSMini2-F1 package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and production continuity. Substitute parts must maintain electrical performance within the specified voltage and current parameters while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MA2S11100L is determined by the following critical parameters:

Primary Electrical Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 80V
• Current - Average Rectified (Io): Must equal or exceed 100mA
• Voltage - Forward (Vf) (Max): Must not exceed 1.2V at rated current
• Technology: Standard rectifier diode classification

Secondary Electrical Criteria:

• Reverse Recovery Time (trr): Acceptable range 3–4ns for small signal applications
• Current - Reverse Leakage @ Vr: Must not exceed 100nA at specified voltage
• Capacitance @ Vr, F: Acceptable range 2–3pF at specified conditions

Mechanical & Environmental Criteria:

• Mounting Type: Surface Mount required
• Operating Temperature - Junction (Max): Must equal or exceed 125°C
• Moisture Sensitivity Level (MSL): Level 1 (Unlimited) preferred for compatibility

Identified Substitutes:

1. BAS16E6327HTSA1 (Infineon Technologies): Meets primary electrical criteria with 80V reverse voltage and 250mA current rating. Exceeds minimum current requirement. Fast recovery classification acceptable for general-purpose applications. Last Time Buy status indicates limited availability.

2. CDSP400-G (Comchip Technology): Meets all primary electrical criteria with 80V reverse voltage and 100mA current rating. Matches forward voltage specification at 1.2V @ 100mA. Active product status ensures ongoing availability. SOD-723 package provides alternative form factor.

Parameter Comparison

Engineering Selection Recommendations

CDSP400-G (Comchip Technology) is the primary substitute for the MA2S11100L. This part maintains identical electrical specifications for voltage, current, and forward voltage characteristics. The CDSP400-G holds Active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance and REACH Unaffected status satisfy regulatory requirements. The SOD-723 package provides a compact alternative to the original SSMini2-F1 form factor, suitable for space-constrained applications. Operating temperature maximum of 125°C is acceptable for standard industrial applications, though 25°C lower than the original specification.

BAS16E6327HTSA1 (Infineon Technologies) serves as a secondary substitute when higher current capacity is required. This part exceeds the 100mA specification with a 250mA rating, providing design margin for applications with variable load conditions. The 80V reverse voltage rating matches the original specification. However, Last Time Buy status indicates this component approaches end-of-life, limiting its suitability for new long-term production programs. The SOT-23-3 package differs from the original form factor and requires PCB layout modification.

Selection Criteria:

• For direct replacement with assured availability: CDSP400-G
• For applications requiring higher current margin: BAS16E6327HTSA1 (subject to supply constraints)
• Package compatibility must be evaluated against existing PCB designs

Frequently Asked Questions (FAQ)

Q: Can the CDSP400-G directly replace the MA2S11100L without circuit modification?

A: The CDSP400-G maintains all critical electrical parameters (80V reverse voltage, 100mA current, 1.2V forward voltage) required for functional equivalence. However, the SOD-723 package differs from the original SSMini2-F1 package, requiring PCB footprint modification. Electrical performance remains unchanged.

Q: What is the significance of the BAS16E6327HTSA1 having a 250mA current rating versus the 100mA specification?

A: The higher current rating provides additional design margin and thermal headroom in applications where load current approaches the 100mA limit. This does not affect compatibility; the part operates safely at 100mA or lower. The higher rating indicates greater thermal capacity and lower junction temperature rise under identical load conditions.

Q: Why does the BAS16E6327HTSA1 show "Last Time Buy" status?

A: Last Time Buy status indicates the manufacturer has announced end-of-production for this component. Existing inventory remains available, but no new production is scheduled. This status makes the part unsuitable for new designs requiring long-term component availability.

Q: Are there package compatibility concerns between the three parts?

A: Yes. The MA2S11100L uses SSMini2-F1 (SC-79, SOD-523) packaging. The CDSP400-G uses SOD-723, and the BAS16E6327HTSA1 uses SOT-23-3 (TO-236-3, SC-59). Each package has different footprint dimensions and pin configurations. PCB design must accommodate the selected substitute package.

Q: What is the impact of the CDSP400-G's 125°C maximum junction temperature versus the original 150°C?

A: The 25°C difference represents reduced thermal margin. For applications operating near maximum ambient temperature or with high power dissipation, this may require thermal analysis. For standard industrial applications with typical thermal management, this difference is acceptable.

Q: Do all three parts meet RoHS and REACH compliance requirements?

A: The CDSP400-G and BAS16E6327HTSA1 explicitly state RoHS3 compliance and REACH Unaffected status. The MA2S11100L specifications provided do not include explicit RoHS status declaration. Both substitutes satisfy modern regulatory requirements for new designs.

Q: Which substitute is recommended for new product designs?

A: The CDSP400-G is recommended for new designs. It maintains identical electrical specifications, holds Active product status ensuring long-term availability, and meets current regulatory compliance standards. Package change requires PCB modification but presents no electrical compatibility issues.
