Key Parameters

Substitute Part Grouping Explanation

Substitution of the KOM 2125-Z photodiode sensor is determined by compatibility across the following critical parameters:

Package and Mechanical Compatibility: Both the main part and substitute must utilize the 3-SMD Gull Wing surface mount package configuration to ensure PCB layout and assembly process compatibility.

Optical Characteristics: The substitute must operate within the near-infrared spectrum with a 120° viewing angle to maintain directional sensitivity and field-of-view requirements.

Diode Architecture: PIN photodiode construction is required to preserve the electrical and spectral response characteristics of the original design.

Electrical Performance: The substitute must support surface mount assembly and operate within compatible voltage and temperature ranges for the target application environment.

Regulatory Compliance: All substitute components must maintain ROHS3 compliance and REACH unaffected status to satisfy manufacturing and environmental standards.

The SFH 2400-Z qualifies as a substitute based on these parameters, despite operating at a different peak wavelength (900nm versus 850nm) within the overlapping spectral range of both components.

Parameter Comparison

Engineering Selection Recommendations

The SFH 2400-Z serves as the active equivalent for the obsolete KOM 2125-Z photodiode sensor. Both components share identical package geometry (3-SMD Gull Wing), viewing angle (120°), diode architecture (PIN), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The SFH 2400-Z is currently in active production status, ensuring long-term component availability and supply chain continuity. The substitute component maintains the same moisture sensitivity level (MSL 4) and surface mount assembly requirements as the original part.

Design integration of the SFH 2400-Z requires evaluation of the following parameter differences: peak wavelength shift from 850nm to 900nm, maximum reverse voltage reduction from 60V to 20V, active area reduction from 4mm²/10mm² to 1mm², and extended operating temperature range to 100°C. These differences must be assessed against specific application requirements to confirm functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SFH 2400-Z be used as a direct replacement for the KOM 2125-Z without PCB modifications?

A: Yes, the SFH 2400-Z utilizes the identical 3-SMD Gull Wing package configuration, permitting direct PCB footprint compatibility without layout changes. Pin assignments and mechanical dimensions are preserved.

Q: What is the primary difference between these two photodiode sensors?

A: The primary difference is the peak wavelength specification: KOM 2125-Z operates at 850nm while SFH 2400-Z operates at 900nm. Both components respond across overlapping spectral ranges (400nm-1100nm and 750nm-1100nm respectively), supporting near-infrared detection applications.

Q: Are there voltage rating considerations when substituting the SFH 2400-Z?

A: Yes. The SFH 2400-Z has a maximum reverse voltage rating of 20V compared to the KOM 2125-Z rating of 60V. Circuit designs must ensure reverse bias voltage does not exceed 20V when using the SFH 2400-Z.

Q: Does the active area difference affect sensor performance?

A: The SFH 2400-Z features a smaller active area (1mm²) compared to the KOM 2125-Z (4mm², 10mm²). This affects light collection efficiency and may impact signal amplitude in low-light applications. Application-specific testing is necessary to confirm performance adequacy.

Q: Are both components compliant with current environmental regulations?

A: Yes, both the KOM 2125-Z and SFH 2400-Z are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity level for these components?

A: Both components are classified as MSL 4 (Moisture Sensitivity Level 4), requiring storage and handling within 72-hour exposure windows to prevent moisture absorption that could compromise solder joint reliability during reflow assembly.
