LED LM301B SPMWHD32AMD7XATSS0 Equivalent & Substitute Parts

Part Overview

The SPMWHD32AMD7XATSS0 is an LED lighting component manufactured by Samsung Semiconductor, Inc., classified as an LM301B series neutral white LED with 4000K color temperature. This surface mount device operates at 2.75V forward voltage with a 65mA test current and delivers 31 lumens at 25°C. The component is housed in a 1212 (3030 Metric) package and is currently in active product status with 898 pieces available in stock.

Equivalent and substitute parts are identified when components share identical electrical performance parameters, mechanical dimensions, and thermal characteristics. Substitution becomes necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design flexibility permits component interchange within the same performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHD32AMD7XATSS0 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Color specification: White, Neutral
• Correlated Color Temperature (CCT): 4000K
• Forward Voltage (Vf): 2.75V typical
• Test Current: 65mA
• Luminous Flux @ 25°C: 31 lm (28–34 lm range)
• Color Rendering Index (CRI): 90
• Lumens per Watt efficiency: 173 lm/W
• Maximum Current rating: 180mA
• Viewing Angle: 120°

Mechanical Parameters:

• Package designation: 1212 (3030 Metric)
• Physical dimensions: 3.00mm × 3.00mm
• Maximum seated height: 0.85mm
• Mounting type: Surface Mount

Thermal Parameters:

• Thermal Resistance: 7.5°C/W

Compliance Parameters:

• Moisture Sensitivity Level: 2A (4 Weeks)
• Product Status: Active

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The SPMWHD32 base product number identifies the component family, with suffix variations indicating packaging or tape configuration differences only.

Engineering Selection Recommendations

Primary Part: SPMWHD32AMD7XATSS0

The SPMWHD32AMD7XATSS0 is an active product with full Samsung Semiconductor manufacturing support. This part number is suitable for new designs and production applications requiring the LM301B neutral white 4000K LED in 3030 package format. Current inventory of 898 pieces supports immediate procurement for standard production volumes.

Substitute Part: SPMWHD32AMD7XAT0S0

The SPMWHD32AMD7XAT0S0 is a direct parametric equivalent with identical electrical, mechanical, and thermal specifications. Both parts share the same base product number (SPMWHD32) and differ only in packaging tape configuration suffix. This substitute part is active and carries significantly higher inventory availability (28755 pieces), making it suitable for high-volume production or when extended supply assurance is required.

Both parts comply with identical regulatory classifications (ECCN: EAR99; HTSUS: 8541.41.0000) and carry the same moisture sensitivity rating (MSL 2A, 4 Weeks). Selection between these two part numbers should be based on procurement lead time requirements and inventory availability rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can SPMWHD32AMD7XAT0S0 be used as a direct replacement for SPMWHD32AMD7XATSS0 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical performance (2.75V, 65mA, 31 lm @ 4000K), mechanical dimensions (3.00mm × 3.00mm, 0.85mm height), and thermal characteristics (7.5°C/W). The suffix difference indicates packaging tape configuration only and does not affect component functionality or PCB assembly compatibility.

Q: What is the difference between the two part numbers?

A: The SPMWHD32AMD7XATSS0 and SPMWHD32AMD7XAT0S0 differ only in their packaging tape suffix designation. Both are manufactured by Samsung Semiconductor, Inc., carry the same LM301B series specification, and deliver identical performance across all electrical, optical, and thermal parameters. The difference is administrative and relates to tape reel configuration for automated assembly equipment.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate at 2.75V forward voltage, 65mA test current, and deliver 31 lumens at 25°C with 173 lm/W efficiency. Thermal resistance is 7.5°C/W for both. Maximum current rating is 180mA for both. Color temperature (4000K), CRI (90), and viewing angle (120°) are identical.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical specifications, they can be used interchangeably within the same circuit design and PCB layout. However, tape configuration differences may require separate handling during automated pick-and-place assembly if equipment is configured for specific tape formats.

Q: What is the moisture sensitivity requirement for storage?

A: Both parts carry MSL 2A rating, requiring storage in controlled humidity conditions for up to 4 weeks before reflow soldering. Standard moisture barrier packaging and desiccant storage are required to maintain component reliability.

Q: Are both parts currently in active production status?

A: Yes. Both SPMWHD32AMD7XATSS0 and SPMWHD32AMD7XAT0S0 are active products with full Samsung Semiconductor support. The SPMWHD32AMD7XAT0S0 carries significantly higher inventory (28755 pieces versus 898 pieces), providing better supply availability for high-volume applications.
