SPMWH1229AD5SGPMSB LED Equivalent & Substitute Parts

Part Overview

The SPMWH1229AD5SGPMSB is a surface-mount LED from Samsung Semiconductor's LM283B series, designed for cool white lighting applications at 6500K color temperature. This component operates at 9.4V forward voltage with a 100mA test current, delivering 120 lumens at 25°C in a compact 2835 metric package (1113 case code).

The SPMWH1229AD5SGPMSB carries a "Not For New Designs" product status designation. This status indicates the component remains available for existing applications and maintenance purposes but is not recommended for new product development initiatives. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to components with active product status for ongoing or future implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1229AD5SGPMSB is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Color specification: White, Cool
• Correlated Color Temperature (CCT): 6500K
• Package / Case designation: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• Forward Voltage (Vf) Typical: 9.4V
• Test Current: 100mA
• Maximum Current: 110mA
• Viewing Angle: 120°
• CRI (Color Rendering Index): 80
• Physical dimensions: 3.50mm × 2.80mm
• Height - Seated (Max): 0.75mm
• Thermal Resistance: 15°C/W
• RoHS Compliance: Required
• MSL Rating: 2A (4 Weeks)

Allowable Variation Parameters:

• Flux @ 25°C: Range tolerance of ±5lm from 120lm nominal (115lm–125lm acceptable)
• Lumens/Watt efficiency: Minor variation acceptable within series performance envelope
• Series designation: LM283B family variants (LM283B, LM283B+)
• Product Status: Active status preferred for new applications; "Not For New Designs" acceptable for replacement scenarios

The SPMWH1229AQ5SGPMSA qualifies as a direct substitute based on full parameter alignment within these criteria.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (Maintenance & Replacement): The SPMWH1229AD5SGPMSB remains suitable for sustaining existing product lines and field replacements. Current inventory of 1092 pieces supports ongoing production requirements for established applications.

For New Product Development: The SPMWH1229AQ5SGPMSA is the recommended selection. This substitute carries Active product status, indicating Samsung's ongoing support and availability commitment. The LM283B+ series variant demonstrates equivalent electrical and mechanical performance with 735 pieces in current inventory. The marginal reduction in luminous flux (117lm versus 120lm nominal) and efficiency (125 lm/W versus 128 lm/W) remains within acceptable engineering tolerances for cool white 6500K LED applications in the 2835 package format.

Compliance & Certification: Both components maintain identical RoHS compliance and MSL ratings (2A, 4 Weeks), ensuring equivalent handling, storage, and assembly process compatibility. No additional qualification or testing is required when transitioning from the main part to the substitute part within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1229AQ5SGPMSA be used as a direct replacement for SPMWH1229AD5SGPMSB in existing assemblies?

A: Yes. Both components share identical electrical characteristics (9.4V forward voltage, 100mA test current, 110mA maximum), identical package dimensions (2835 metric, 3.50 × 2.80mm), and identical thermal properties (15°C/W). The luminous flux difference (117lm versus 120lm) falls within the specified tolerance band and does not affect circuit functionality or thermal management.

Q: What is the significance of the "Not For New Designs" status on SPMWH1229AD5SGPMSB?

A: This designation indicates the component is in mature or declining production phase. Samsung continues to supply existing inventory for maintenance and replacement purposes, but recommends new product designs adopt the SPMWH1229AQ5SGPMSA (LM283B+ series) for long-term availability assurance and design continuity.

Q: Are there any handling or storage differences between these two parts?

A: No. Both components carry identical MSL ratings (2A, 4 Weeks), requiring the same moisture control protocols, reflow temperature profiles, and storage conditions. No process modifications are necessary when substituting one part for the other.

Q: How do the luminous efficiency values compare?

A: The main part delivers 128 lm/W while the substitute provides 125 lm/W at the 100mA test current. This 3 lm/W difference represents approximately 2.3% variation and remains within normal manufacturing tolerance for LED components in this category. Both values support equivalent lighting performance in 6500K cool white applications.

Q: Is the color temperature specification identical between both parts?

A: Yes. Both components are specified at 6500K correlated color temperature with CRI 80. Color appearance and rendering characteristics are equivalent for cool white lighting applications.

Q: What inventory status should influence component selection?

A: The SPMWH1229AQ5SGPMSA (735 pieces) offers higher current availability than SPMWH1229AD5SGPMSB (1092 pieces). For high-volume production or long-term supply planning, the substitute part's Active status provides greater assurance of sustained availability beyond current inventory levels.
