Engineering Selection Recommendations

Substitution Feasibility Assessment:

All listed CreeLED substitute parts are compatible with the QBHP684UE-PCAV footprint and mounting process. However, circuit-level design changes are required due to electrical parameter differences.

Critical Design Considerations:

Forward Voltage Difference: The QBHP684UE-PCAV operates at 3.8V typical forward voltage, while all CreeLED substitutes operate at 2.1V to 2.2V. This 1.6V to 1.7V reduction requires recalculation of series resistor values and power supply voltage compatibility. Existing current-limiting circuits designed for 3.8V will overdrive substitute parts at the same supply voltage.
Current Rating Mismatch: The original part is rated for 700mA maximum current. XP-C series substitutes (XPCAMB-L1-0000-00201, XPCAMB-L1-0000-00301, XPCAMB-L1-0000-00403) are rated for 350mA maximum. XP-E series substitutes support 500mA maximum. XP-E2 substitute (XPEBAM-L1-0000-00601) supports 1000mA maximum. Circuit current must be adjusted to match the selected substitute's maximum rating.
Thermal Management: The original part has superior thermal resistance (4°C/W) compared to XP-C substitutes (15°C/W). XP-E series offers intermediate thermal performance (10°C/W). XP-E2 provides the best thermal performance (7°C/W). Thermal design review is required for high-power applications.
Product Status & Supply Chain: All CreeLED substitutes carry Active product status, ensuring long-term availability and manufacturing continuity. The original QBHP684UE-PCAV is obsolete, making substitution necessary for new designs and long-term production support.
Regulatory Compliance: All substitute parts are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Original part compliance status is not specified.

Recommended Substitution Path:

For applications requiring maximum current capability and thermal performance, select XPEBAM-L1-0000-00601 (XP-E2 series, 1000mA maximum, 7°C/W thermal resistance). For cost-optimized designs with moderate current requirements, select XPEAMB-L1-0000-00901 (XP-E series, 500mA maximum, 10°C/W thermal resistance, highest efficiency at 114 lm/W). For lowest-cost substitution with minimal circuit modification, select XPCAMB-L1-0000-00301 (XP-C series, 350mA maximum, 15°C/W thermal resistance).

Frequently Asked Questions (FAQ)

Q1: Can I directly replace QBHP684UE-PCAV with a CreeLED substitute without circuit modification?

No. The forward voltage difference (3.8V original vs. 2.1V–2.2V substitutes) requires recalculation of series resistor values and verification of power supply voltage compatibility. Direct substitution without circuit redesign will result in excessive current and component failure.

Q2: Which substitute part has the closest electrical performance to the original QBHP684UE-PCAV?

XPEAMB-L1-0000-00901 (XLamp® XP-E series) provides the highest luminous flux output (84 lm at 350mA test current) and efficiency (114 lm/W), closest matching the original part's high-power characteristics. However, the lower forward voltage (2.1V vs. 3.8V) still requires circuit redesign.

Q3: Are all substitute parts compatible with the same PCB footprint as QBHP684UE-PCAV?

All substitute parts use the 1414 (3535 metric) surface-mount package. However, substitute parts have slightly smaller body dimensions (3.45mm x 3.45mm vs. 3.60mm x 3.60mm original) and different maximum seated heights (2.13mm or 2.39mm vs. 1.90mm original). PCB footprints designed for the original part will accommodate substitutes, but clearance verification is recommended for high-density layouts.

Q4: What is the maximum current I can operate a substitute part at?

Current limits vary by series: XP-C series (XPCAMB models) = 350mA maximum; XP-E series (XPEAMB models) = 500mA maximum; XP-E2 series (XPEBAM-L1-0000-00601) = 1000mA maximum. Circuit design must not exceed the selected substitute's maximum current rating.

Q5: Do the substitute parts have better thermal performance than the original?

The original QBHP684UE-PCAV has superior thermal resistance (4°C/W). XP-C substitutes have thermal resistance of 15°C/W (worse). XP-E substitutes have 10°C/W (intermediate). XP-E2 substitute has 7°C/W (better than XP-E but still higher than original). For thermally constrained applications, XP-E2 is recommended.

Q6: Are the substitute parts RoHS and REACH compliant?

Yes. All CreeLED substitute parts listed are RoHS Compliant and REACH Unaffected. Original part compliance status is not specified in available documentation.

Q7: What is the viewing angle difference between the original and substitutes?

Original QBHP684UE-PCAV: 130° viewing angle. XP-C substitutes: 125° viewing angle. XP-E and XP-E2 substitutes: 130° viewing angle. The 5° difference in XP-C series is negligible for most applications but should be verified for optical design requirements.

Q8: Which substitute offers the best efficiency (lumens per watt)?

XPEAMB-L1-0000-00901 (XLamp® XP-E series) provides the highest efficiency at 114 lm/W at 350mA test current. This represents a 192% efficiency improvement over the original part (39 lm/W).

Q9: Can I use a substitute part rated for lower maximum current in a circuit designed for 700mA operation?

No. Operating a component above its maximum current rating causes permanent damage. If the original circuit requires 700mA operation, only XPEBAM-L1-0000-00601 (1000mA maximum) is suitable without circuit redesign. Lower-rated substitutes require circuit modification to reduce operating current.

Q10: What is the lead time and inventory status for substitute parts?

Inventory levels vary: XPEAMB-L1-0000-00901 has the highest stock (10,926 pcs), followed by XPCAMB-L1-0000-00301 (1,778 pcs). All substitute parts are manufactured by CreeLED with Active product status, ensuring ongoing availability. Original QBHP684UE-PCAV is obsolete with limited remaining inventory (957 pcs).
