Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1412566

The Phoenix Contact 1412566 is the direct substitute for the obsolete 1421879. Selection is based on:

1. Product Status: The 1412566 maintains active product status, ensuring long-term availability and continued manufacturer support, whereas the 1421879 is obsolete.

2. Regulatory Compliance: Both parts maintain equivalent RoHS compliance levels (RoHS Compliant vs. ROHS3 Compliant), with the substitute meeting current regulatory standards.

3. Series Continuity: Both components belong to the HEAVYCON connector family with identical B6 size designation, ensuring mechanical and electrical compatibility within existing connector systems.

4. Environmental Classification: Identical MSL rating (1 - Unlimited) confirms equivalent moisture and environmental tolerance for storage and handling.

5. Trade Classification: Matching ECCN (EAR99) and HTSUS (8538.90.8180) codes confirm identical export control and tariff treatment.

The substitute part provides enhanced specifications including defined ingress protection (IP66/IP69K) and operating temperature range (-40°C ~ 125°C), offering improved performance characteristics for industrial applications.

Frequently Asked Questions (FAQ)

Q: Why is the 1421879 no longer available?

A: The Phoenix Contact 1421879 has reached end-of-life status and is classified as obsolete. The 1412566 represents the active equivalent within the HEAVYCON B series product line.

Q: Are the 1421879 and 1412566 mechanically compatible?

A: Both components share the same size designation (B6) and belong to the HEAVYCON connector series. Mechanical compatibility is maintained for connector assembly applications.

Q: What is the difference between the two parts?

A: The primary differences are product status (obsolete vs. active) and specification documentation. The 1412566 provides detailed specifications including IP66/IP69K ingress protection and operating temperature range (-40°C ~ 125°C), which were not specified for the 1421879.

Q: Do both parts meet RoHS requirements?

A: Yes. The 1421879 is RoHS Compliant, and the 1412566 is ROHS3 Compliant, confirming both parts meet current and historical RoHS standards.

Q: What is the packaging difference?

A: The 1412566 is supplied in Bulk packaging. Packaging specifications for the 1421879 were not provided in the original documentation.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating identical moisture sensitivity classification and equivalent handling requirements.

Q: Can the 1412566 be used as a direct replacement in existing systems?

A: The 1412566 maintains compatibility with HEAVYCON B6 connector systems. Verification of mechanical fit and electrical interface requirements within specific system designs is necessary during integration planning.
