Key Parameters

Substitute Part Grouping Explanation

Substitution of the QSE214 is based on electrical and mechanical parameter equivalence. The QSE114 qualifies as a direct substitute because it maintains identical specifications across all critical parameters: 880nm wavelength, 50° viewing angle, 30V collector-emitter breakdown voltage, 100nA maximum dark current, 100mW maximum power dissipation, through-hole mounting, side view orientation, and -40°C to 100°C operating temperature range. Both components use identical radial, side view packaging. The primary distinction is product status: QSE214 is obsolete while QSE114 is active, with QSE114 offering continued availability and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The QSE114 is the direct equivalent for QSE214 applications. Selection should prioritize QSE114 for new designs and production continuity due to its active product status and RoHS3 compliance certification. Both components are REACH unaffected and share identical electrical performance and mechanical form factors. The QSE114 provides regulatory compliance assurance and ongoing manufacturer support, eliminating obsolescence risk associated with QSE214.

Frequently Asked Questions (FAQ)

Q: Can QSE114 replace QSE214 in existing designs? A: Yes. QSE114 is electrically and mechanically equivalent to QSE214 across all specified parameters, including wavelength, voltage ratings, dark current, power dissipation, mounting type, orientation, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the primary reason to switch from QSE214 to QSE114? A: QSE214 is classified as obsolete, while QSE114 is active. QSE114 ensures continued availability, manufacturer support, and regulatory compliance (RoHS3). Transitioning to QSE114 eliminates supply chain risk.

Q: Are there packaging differences between QSE214 and QSE114? A: No. Both components use identical radial, side view packaging suitable for through-hole mounting. Physical dimensions and pin configurations are equivalent.

Q: Do both parts meet the same regulatory requirements? A: Both QSE214 and QSE114 are REACH unaffected. QSE114 additionally carries RoHS3 compliance certification, providing enhanced regulatory assurance for applications subject to RoHS requirements.

Q: Is there an inventory advantage to selecting QSE114? A: Yes. QSE114 has 4945 units in stock compared to QSE214's 728 units, providing greater availability for production planning.
