SPMWH1221FD7GBTKSA LED Equivalent & Substitute Parts

Part Overview

The SPMWH1221FD7GBTKSA is a surface-mount LED lighting component manufactured by Samsung Semiconductor, Inc., classified within the LM282B series. This neutral white LED operates at 4000K color temperature and delivers 110 lumens at 25°C under 150mA test current. The component is housed in a 2835 metric package (1113 case designation) with a 120° viewing angle.

This part carries a "Not For New Designs" product status designation. Identifying equivalent and substitute parts is necessary for ongoing production support, inventory management, and design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1221FD7GBTKSA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Series: LM282B
• Color: White, Neutral
• CCT: 4000K
• Package / Case: 1113 (2835 Metric)
• Flux @ 25°C, 150mA: 110 lm (105–115 lm range)
• Forward Voltage (Vf): 6.3V
• Test Current: 150mA
• Maximum Current: 160mA
• Viewing Angle: 120°
• Thermal Resistance: 15°C/W
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Variable Parameter (Allows Substitution):

• CRI (Color Rendering Index): The main part specifies CRI 90. Substitute parts with CRI 80 are functionally equivalent within the LM282B series specification, as both values fall within the neutral white LED performance envelope for this product category.

All four substitute parts listed below meet these criteria and are direct parametric equivalents of SPMWH1221FD7GBTKSA.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are direct parametric equivalents of SPMWH1221FD7GBTKSA within the LM282B series specification. Selection among these parts should be based on the following engineering criteria:

CRI Consideration:

• SPMWH1221FD7GBTKSA, SPMWH1221FD7GBT0SA, and SPMWH1221FD7GBTMSA feature CRI 90, matching the original part specification.
• SPMWH1221FD5GBT0SA and SPMWH1221FD5GBTMSA feature CRI 80, which is acceptable for applications where color rendering requirements are less stringent.

Compliance & Certification: All substitute parts carry identical RoHS compliance status and MSL ratings (2A, 4 Weeks), ensuring equivalent environmental and handling requirements.

Product Status: All parts, including the main part and substitutes, carry "Not For New Designs" designation. This status applies uniformly across the LM282B series and does not differentiate substitution eligibility.

Inventory Availability: Substitute parts demonstrate significantly higher inventory levels than the main part, ranging from 16,508 to 49,017 pieces, compared to 758 pieces for SPMWH1221FD7GBTKSA. This availability differential supports substitution for production continuity.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1221FD5GBT0SA or SPMWH1221FD5GBTMSA be used as direct replacements for SPMWH1221FD7GBTKSA?

A: Yes. Both parts are parametric equivalents. The difference is CRI: the FD5 variants have CRI 80, while the main part has CRI 90. All other electrical, optical, and mechanical parameters are identical. Selection depends on application color rendering requirements.

Q: What is the difference between the FD7 and FD5 designations in the part number?

A: The FD7 and FD5 designations indicate different CRI specifications within the same LM282B series. FD7 parts specify CRI 90; FD5 parts specify CRI 80. Both are valid for neutral white 4000K LED applications.

Q: Are the packaging and mounting characteristics identical across all substitute parts?

A: Yes. All parts use identical 1113 (2835 metric) surface-mount packages with 3.50 × 2.80 mm footprints and 0.75 mm maximum seated height. All are supplied in Tape & Reel packaging. PCB layout and reflow profiles are interchangeable.

Q: Do the substitute parts have the same thermal and electrical performance?

A: Yes. Forward voltage (6.3V typical), test current (150mA), maximum current (160mA), thermal resistance (15°C/W), and luminous flux (110 lm at 25°C, 150mA) are identical across all parts. Lumens per watt efficiency is 116 lm/W for all variants.

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

A: This designation indicates that Samsung Semiconductor, Inc. does not recommend these parts for new product development. However, all parts remain functionally equivalent and suitable for production support, maintenance, and existing design continuity. The status applies uniformly to the main part and all substitutes.

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

A: No. All parts carry identical MSL 2A (4 Weeks) moisture sensitivity ratings and RoHS compliance status. Handling, storage, and reflow procedures are identical.
