Substitute Part Grouping Explanation

Substitution of the PDB-C142F is determined by strict equivalence across the following critical parameters:

• Wavelength: 660nm (primary optical specification)
• Diode Type: PIN architecture
• Response Time: 50ns (temporal performance)
• Active Area: 4.12mm² (optical aperture)
• Viewing Angle: 40° (angular field of view)
• Package / Case: Radial, 5mm Dia (T 1 3/4) (mechanical compatibility)
• Mounting Type: Through Hole (PCB integration method)
• Operating Temperature Range: -40°C to 80°C (environmental specification)

The PDB-C142 qualifies as a direct substitute based on matching all critical parameters. The primary distinction is product status: PDB-C142 is active production, whereas PDB-C142F is obsolete.

Engineering Selection Recommendations

The PDB-C142 is the direct equivalent for PDB-C142F applications. Selection is based on the following engineering criteria:

Product Status: PDB-C142 is in active production, ensuring long-term availability and supply chain continuity, whereas PDB-C142F is obsolete and subject to inventory depletion.

Compliance: PDB-C142 carries RoHS Compliance certification, meeting regulatory requirements for new designs and manufacturing environments with restricted substance policies.

Electrical Performance: PDB-C142 provides a higher maximum reverse voltage rating (100V versus 50V), offering improved design margin in reverse-bias applications without compromising forward optical performance.

Optical and Mechanical Specifications: Both parts maintain identical wavelength, response time, active area, viewing angle, and package geometry, ensuring direct pin-for-pin and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can PDB-C142 replace PDB-C142F in existing designs?

A: Yes. The PDB-C142 is mechanically and electrically compatible with PDB-C142F. Both components share identical package geometry (Radial, 5mm Dia T 1 3/4), mounting type (Through Hole), and critical optical parameters (660nm wavelength, 50ns response time, 40° viewing angle, 4.12mm² active area). No PCB redesign is required.

Q: What is the difference in reverse voltage rating?

A: PDB-C142F is rated for 50V maximum DC reverse voltage, while PDB-C142 is rated for 100V. This difference does not affect forward-biased photodiode operation. If your circuit applies reverse bias below 50V, both parts are equivalent. If reverse bias exceeds 50V but remains below 100V, PDB-C142 provides additional design margin.

Q: Why is PDB-C142F obsolete?

A: Product obsolescence is determined by the manufacturer. PDB-C142 is the active production equivalent and is recommended for all new designs and legacy system support.

Q: Are there packaging differences?

A: PDB-C142F is specified with packaging designation "-" (not detailed), while PDB-C142 is supplied in Bulk packaging. Both use identical component packaging (Radial, 5mm Dia T 1 3/4). Bulk packaging refers to distribution format, not component form factor.

Q: Is PDB-C142 RoHS compliant?

A: Yes. PDB-C142 is RoHS Compliant. If your application or manufacturing process requires RoHS compliance, PDB-C142 meets this requirement. RoHS compliance status is not specified for PDB-C142F.

Q: What is the spectral range difference?

A: PDB-C142F spectral range is 700nm ~ 1100nm, while PDB-C142 spectral range is 400nm ~ 1100nm. Both are optimized for 660nm operation. The broader spectral range of PDB-C142 indicates enhanced sensitivity across a wider optical spectrum without affecting 660nm performance.
