3M 40049 Equivalent & Substitute Parts Reference

Part Overview

The 3M 40049 is a SCOTCHLOK aluminum one-hole lug terminal connector classified as a ring terminal connector. This component is currently active in the product portfolio and maintains an inventory of 3,693 pieces in new original stock. The part is RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit functional equivalents that meet the same electrical and mechanical specifications. The LAA250-12-5 from Panduit Corp serves as a documented manufacturer-recommended substitute for this application.

Engineering Selection Recommendations

3M 40049 Selection Criteria:

• Primary choice for new designs and applications requiring active product status
• Maintains current manufacturing support and availability
• Recommended for applications where long-term supply continuity is required

Panduit LAA250-12-5 Selection Criteria:

• Suitable as a substitute when 3M 40049 availability is constrained
• Meets equivalent regulatory compliance requirements (ROHS3 and REACH unaffected)
• Shares identical tariff classification and export control designation
• Note: Product status is discontinued at DiGi Electronics; verify current availability through alternative distribution channels before design implementation

Both parts maintain compliance with RoHS3 and REACH regulations, ensuring compatibility with current electronic component procurement standards. Selection between these parts should be based on availability, supply chain requirements, and application-specific lead time constraints.

Frequently Asked Questions (FAQ)

Q: What makes LAA250-12-5 a valid substitute for 3M 40049? A: Both parts are aluminum terminal connectors sharing identical regulatory compliance status (RoHS3 compliant, REACH unaffected), the same tariff classification (HTSUS 8536.90.4000), and equivalent export control designation (EAR99). The substitution is based on manufacturer documentation and material compatibility.

Q: Can I use LAA250-12-5 as a direct replacement in existing designs? A: The LAA250-12-5 is documented as a manufacturer-recommended substitute. However, verify that the specific mechanical dimensions, wire gauge ratings, and stud/tab sizes meet your application requirements before implementation. Consult detailed specification sheets for both parts to confirm dimensional compatibility.

Q: What is the current availability status of these parts? A: The 3M 40049 maintains active product status with 3,693 pieces in new original stock. The Panduit LAA250-12-5 is discontinued at DiGi Electronics; availability through other distribution channels should be verified independently.

Q: Are there any regulatory differences between these parts? A: Both parts are RoHS3 compliant and REACH unaffected. They share identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent regulatory treatment for procurement and export purposes.

Q: What packaging options are available? A: The 3M 40049 packaging specification is not provided in the available data. The Panduit LAA250-12-5 is supplied in bulk packaging. Contact manufacturers directly for specific packaging configurations and minimum order quantities.
