Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts are classified as Active products, ensuring long-term availability and manufacturing support. The original part SPMWHT541MH7WAWKSB is obsolete and should be replaced in new designs and production runs.

Recommended Substitutes by Inventory Availability:

SPMWHT541MP5WASMS5 - 25,826 Pcs in stock. Highest inventory level ensures supply chain continuity.
SPMWHT541MP5WASMS4 - 25,748 Pcs in stock. Second highest inventory availability.
SPMWHT541MP5WAS0S4 - 25,612 Pcs in stock. Third highest inventory availability.
SPMWHT541MP5WAS0S5 - 25,100 Pcs in stock. Substantial inventory for production requirements.

Compliance Verification:

All substitute parts maintain RoHS Compliant status and identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000). Moisture Sensitivity Level (MSL) 2A (4 Weeks) is consistent across all active alternatives, ensuring equivalent handling and storage requirements.

Packaging Consideration:

Substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly operations. This packaging format is compatible with standard pick-and-place equipment used in surface mount technology (SMT) manufacturing.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 directly replace SPMWHT541MH7WAWKSB in existing designs?

A: Yes. Both parts share identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), mechanical dimensions (5.00mm x 3.00mm, 0.80mm height), and thermal characteristics (15°C/W). The 4-SMD flat lead package and 5630 form factor are equivalent. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between the various substitute part numbers?

A: The substitute part numbers differ in their suffix codes (S4, S5, MS4, MS5, NS4, NS5, SK4, SK5), which indicate manufacturing lot codes or packaging variants within the same electrical and mechanical specification. All variants maintain identical performance parameters and are interchangeable from an engineering standpoint.

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

A: No. All substitute parts are specified with identical forward voltage (2.95V typical), test current (65mA), maximum current (180mA), viewing angle (120°), CRI (80), and thermal resistance (15°C/W). Performance is equivalent across all variants.

Q: What is the significance of the Tape & Reel packaging for substitute parts?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly. It is compatible with standard pick-and-place equipment and reflow soldering processes. This packaging format is preferred for production environments and does not affect component functionality or performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS Compliant status, identical to the original part. Regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) are consistent across all alternatives.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: All substitute parts are rated MSL 2A (4 Weeks), indicating they must be stored in controlled humidity environments and used within four weeks of opening the moisture barrier bag. This specification is identical to the original part and requires standard handling procedures for surface mount components.

Q: Which substitute part should be selected for new production?

A: SPMWHT541MP5WASMS5 or SPMWHT541MP5WASMS4 are recommended due to highest inventory availability (25,826 Pcs and 25,748 Pcs respectively), ensuring supply chain stability for ongoing production requirements. All active substitutes are functionally equivalent and suitable for new designs.
