FS2M-TP Equivalent & Substitute Parts

Part Overview

The FS2M-TP is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (HSMA) package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The FS2M-TP remains functionally available through active equivalent models that maintain identical electrical specifications and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the FS2M-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage Rating: 1000 V DC reverse voltage (Vr)
Current Rating: 2 A average rectified current (Io)
Recovery Characteristics: Fast recovery classification with 500 ns reverse recovery time (trr)
Reverse Leakage: 5 µA @ 1000 V
Capacitance: 50 pF @ 4V, 1MHz
Package Type: DO-214AC surface mount configuration
Temperature Range: -50°C to 150°C junction operating temperature
Compliance: ROHS3 compliance and MSL 1 rating

The FS2M-TP and its substitute maintain identical base product designation (FS2M) and share all critical electrical parameters. The primary distinction lies in product status and packaging configuration, not in functional performance.

Engineering Selection Recommendations

FS2M-LTP is the direct substitute for FS2M-TP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications, thermal characteristics, and compliance certifications.

The FS2M-TP is classified as obsolete, while the FS2M-LTP maintains active product status. For new designs and ongoing procurement, the FS2M-LTP is the appropriate selection. Both parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) classification, indicating equivalent handling and storage requirements.

The functional difference between these parts is limited to packaging configuration: FS2M-TP is supplied in bulk form, while FS2M-LTP is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can FS2M-LTP be used as a direct replacement for FS2M-TP in existing designs?

A: Yes. The FS2M-LTP is electrically and mechanically equivalent to the FS2M-TP. All electrical parameters, thermal ratings, and compliance certifications are identical. The components are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between FS2M-TP and FS2M-LTP?

A: The primary difference is product status and packaging. The FS2M-TP is obsolete and supplied in bulk packaging, while the FS2M-LTP is an active product supplied in Tape & Reel (TR) format. Electrical specifications and performance characteristics are identical.

Q: Are there any compatibility concerns when substituting FS2M-LTP for FS2M-TP?

A: No compatibility concerns exist for circuit operation. Both components are surface mount diodes in the DO-214AC package with identical pinouts and electrical ratings. Tape & Reel packaging (FS2M-LTP) may require different handling in assembly processes compared to bulk packaging (FS2M-TP), but this is a procurement and manufacturing consideration, not a circuit compatibility issue.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage rating (1000 V), current rating (2 A), reverse recovery time (500 ns), reverse leakage current (5 µA @ 1000 V), and capacitance (50 pF @ 4V, 1MHz). Both FS2M-TP and FS2M-LTP meet all these criteria.

Q: Is the FS2M-LTP available in the same package as the FS2M-TP?

A: Yes. Both components use the DO-214AC (SMA) surface mount package. The package type and pinout are identical. The difference is in the supply format: bulk versus Tape & Reel.

Q: What compliance certifications apply to both parts?

A: Both FS2M-TP and FS2M-LTP are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity level classification. These certifications are equivalent across both parts.
