Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAVGS4 are classified into two categories based on electrical and mechanical compatibility:

Category 1: Direct Series Equivalent The SPMWHT541MP5WAVMS4 is a direct equivalent within the same LM561B Plus series. This substitute maintains identical electrical characteristics (2.95V Vf, 65mA test current, 3000K CCT, 80 CRI) and mechanical specifications (5630 package, 4-SMD flat leads, 120° viewing angle, 0.80mm height). The primary distinction is product status: SPMWHT541MP5WAVMS4 is Active, whereas the main part is Not For New Designs. This substitute is selected when maintaining the exact LM561B Plus performance profile is required.

Category 2: Parametric Equivalents (LM281B+ Series) The parts SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, and SPMWH1228FD5W2VMSJ represent parametric equivalents from the LM281B+ series. These substitutes share the following allowed parameters: 3000K CCT, 80 CRI, white warm color, 120° viewing angle, 5630 package, 4-SMD flat leads, 0.80mm height, and surface mount configuration. These parts differ in test current (150mA vs. 65mA), forward voltage (2.9V vs. 2.95V), and thermal resistance (25°C/W vs. 20°C/W). All LM281B+ variants are Active products with ROHS3 compliance.

Substitution logic is based strictly on: color temperature matching (3000K), color rendering index (80), package form factor (5630 4-SMD), mechanical dimensions, viewing angle, and compliance certifications. No performance assumptions or testing recommendations are applied.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series Performance): Select SPMWHT541MP5WAVMS4 when the LM561B Plus series characteristics are required and the design can accommodate an Active product status. This part maintains identical electrical specifications (2.95V, 65mA test current) and thermal resistance (16°C/W, improved from 20°C/W). SPMWHT541MP5WAVMS4 carries ROHS3 compliance, exceeding the RoHS Compliant status of the original part. Inventory availability is significantly higher (50,200 pcs vs. 722 pcs).

For Parametric Substitution (LM281B+ Series): Select from SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, or SPMWH1228FD5W2VMSJ when design flexibility permits operation at higher test current (150mA vs. 65mA) and slightly lower forward voltage (2.9V vs. 2.95V). These LM281B+ variants maintain color temperature (3000K), CRI (80), package form factor (5630), and mechanical dimensions. All three LM281B+ options are Active products with ROHS3 compliance and REACH Unaffected status. Selection among the three LM281B+ variants is based on inventory availability and supply chain requirements.

Compliance Considerations: All substitute parts meet or exceed the RoHS compliance requirement of the original part. SPMWHT541MP5WAVMS4 and all LM281B+ variants carry ROHS3 certification. The LM281B+ series additionally carries REACH Unaffected status, providing enhanced regulatory coverage.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct drop-in replacement for SPMWHT541MP5WAVGS4?

A: Yes. SPMWHT541MP5WAVMS4 is a direct equivalent within the LM561B Plus series. Both parts share identical electrical specifications (2.95V Vf, 65mA test current, 3000K CCT, 80 CRI) and mechanical dimensions (5630 package, 4-SMD flat leads, 0.80mm height, 120° viewing angle). The primary difference is product status: SPMWHT541MP5WAVMS4 is Active, whereas SPMWHT541MP5WAVGS4 is Not For New Designs. SPMWHT541MP5WAVMS4 also features improved thermal resistance (16°C/W vs. 20°C/W) and ROHS3 compliance.

Q: What are the key differences between the LM561B Plus and LM281B+ series substitutes?

A: The LM281B+ series (SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, SPMWH1228FD5W2VMSJ) differs from LM561B Plus in three electrical parameters: test current (150mA vs. 65mA), forward voltage (2.9V vs. 2.95V), and thermal resistance (25°C/W vs. 20°C/W). Color temperature (3000K), CRI (80), package form factor (5630), mechanical dimensions, and viewing angle (120°) remain identical. All LM281B+ variants are Active products with ROHS3 and REACH Unaffected status.

Q: Are the 5630 package dimensions identical across all substitute parts?

A: Yes. All substitute parts maintain the 5630 package specification with dimensions of 5.00mm length x 3.00mm width and maximum seated height of 0.80mm. The 4-SMD flat leads configuration is consistent across all parts. Surface mount mounting type is identical for all variants.

Q: Which substitute part should be selected for new design implementations?

A: For new designs, select either SPMWHT541MP5WAVMS4 (if LM561B Plus series performance is required) or any of the LM281B+ variants (SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, SPMWH1228FD5W2VMSJ). All four substitute parts carry Active product status. The original SPMWHT541MP5WAVGS4 is designated "Not For New Designs" and should not be used in new implementations.

Q: What is the significance of ROHS3 compliance versus RoHS Compliant status?

A: ROHS3 represents the current regulatory standard for restriction of hazardous substances, superseding earlier RoHS compliance designations. All substitute parts carry ROHS3 certification, providing compliance with current environmental and safety regulations. The original part carries RoHS Compliant status, which is acceptable but represents an earlier compliance framework.

Q: Can the LM281B+ series parts be used in applications designed for 65mA operation?

A: The LM281B+ series parts are rated for 150mA test current and 200mA maximum current, compared to 65mA test current and 180mA maximum for LM561B Plus. While LM281B+ parts can operate at lower currents, they are specified for higher current operation. Circuit design and thermal management must account for the different electrical characteristics (2.9V vs. 2.95V forward voltage, 25°C/W vs. 20°C/W thermal resistance).

Q: Are there inventory differences among the three LM281B+ variants?

A: Yes. SPMWH1228FD5W2VKSJ has 1,134 pcs in stock, SPMWH1228FD5W2VMSJ has 950 pcs, and SPMWH1228FD5W2V0SJ has 954 pcs. All three variants are electrically and mechanically identical. Selection among them should be based on supply chain availability and procurement requirements.
