LXR7-SW65 Equivalent & Substitute Parts

Part Overview

The LXR7-SW65 is a LUXEON M series surface-mount LED from Lumileds, engineered for cool white lighting applications at 6500K color temperature. This Active product delivers 1060 lm typical output at 85°C under 700mA test current, with a forward voltage of 11.2V and 135 lm/W efficiency. The 2828 (7070 Metric) package provides a compact 7.00mm × 7.00mm footprint suitable for high-density lighting designs. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across the LUXEON M platform.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LXR7-SW65 are qualified based on the following criteria:

Electrical Compatibility: Forward voltage (11.2V), test current (700mA), maximum current (1.2A), and thermal resistance (1.25°C/W) must remain constant to ensure direct circuit compatibility without redesign.

Optical Performance: Flux output (1060 lm @ 85°C), lumens/watt efficiency (135 lm/W), CRI (70), and viewing angle (120°) must be maintained for functional equivalence.

Mechanical Compatibility: Package type (2828 / 7070 Metric), footprint (7.00mm × 7.00mm), and height (3.87mm max) must match for PCB assembly without modification.

Compliance & Status: Product must be Active status with ROHS3 compliance, MSL 1, and REACH Unaffected designation.

Allowed Variation: Color temperature (CCT) may differ within the cool white spectrum while all other parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The LXR7-SW57 qualifies as a direct parametric equivalent to the LXR7-SW65. Both parts maintain identical electrical specifications (11.2V forward voltage, 700mA test current, 1.2A maximum), optical performance (1060 lm, 135 lm/W, CRI 70, 120° viewing angle), and mechanical form factor (2828 package, 7.00mm × 7.00mm, 3.87mm height). Both are Active products with ROHS3 compliance and MSL 1 rating.

The sole difference is color temperature: LXR7-SW65 operates at 6500K while LXR7-SW57 operates at 5700K. Both fall within the cool white spectrum. Selection between these parts depends on application-specific color temperature requirements. No circuit redesign or thermal management modifications are required when substituting between these parts.

Both parts carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN, HTSUS 8541.41.0000), confirming regulatory equivalence for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can LXR7-SW57 replace LXR7-SW65 in existing designs?

A: Yes. The LXR7-SW57 is electrically and mechanically equivalent. No circuit modifications are required. The only difference is color temperature (5700K vs. 6500K). If the application tolerates this color temperature shift, direct substitution is valid.

Q: What is the difference between 6500K and 5700K color temperature?

A: Both are cool white LEDs. 6500K (LXR7-SW65) produces a slightly cooler, more daylight-like appearance. 5700K (LXR7-SW57) produces a marginally warmer cool white. The difference is perceptually subtle. Application requirements determine which is appropriate.

Q: Are the forward voltage and current ratings identical?

A: Yes. Both parts operate at 11.2V forward voltage (typical), 700mA test current, and 1.2A maximum current. Existing power supply and current-limiting circuits require no adjustment.

Q: Do both parts use the same package and footprint?

A: Yes. Both use the 2828 (7070 Metric) surface-mount package with 7.00mm × 7.00mm footprint and 3.87mm maximum height. PCB layouts and pick-and-place programming remain unchanged.

Q: Are thermal characteristics the same?

A: Yes. Both parts have 1.25°C/W thermal resistance. Thermal management design, heatsinking, and thermal simulation results remain valid when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both are ROHS3 compliant, MSL 1 (unlimited moisture sensitivity level), and REACH Unaffected. Both carry EAR99 ECCN and HTSUS 8541.41.0000 classification.

Q: Can I mix LXR7-SW65 and LXR7-SW57 in the same assembly?

A: Electrically and thermally, yes. Optically, mixing introduces two different color temperatures in the same fixture, which may produce visible color inconsistency depending on application. Homogeneous color temperature typically requires using a single part number across the assembly.
