Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1452987 qualifies as a direct substitute based on the following alignment of critical parameters:

• Accessory Type: Both are actuator boxes
• Shell Size - Insert: Both support M12 connectors
• Connector Openings: Both provide 4 connector openings
• Environmental Protection: Both feature dust tight and waterproof construction
• RoHS Compliance: Both meet RoHS requirements
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

The primary differences are material composition (Polyamide vs. Polybutylene Terephthalate) and product status (Obsolete vs. Active). The 1452987 is currently in active production with available inventory.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1452987 is the direct equivalent for the obsolete 1671221. Both components maintain identical functional specifications for M12 circular connector applications with four connector openings and equivalent environmental protection ratings.

The 1452987 is recommended for new procurement due to its active product status and current inventory availability. Both parts satisfy RoHS compliance requirements and carry identical export classification (EAR99).

Material substitution from Polyamide to Polybutylene Terephthalate does not affect the specified electrical or mechanical interface parameters for this accessory category.

Frequently Asked Questions (FAQ)

Q: Can the 1452987 directly replace the 1671221 in existing installations?

A: Yes. Both components share identical specifications for shell size (M12), connector opening count (4), and environmental protection features (dust tight, waterproof). The material difference does not affect functional compatibility.

Q: What is the significance of the material change from Polyamide to PBT?

A: Both materials meet the specified environmental protection and RoHS compliance requirements. The material change reflects manufacturing updates in the active product line and does not alter the component's electrical or mechanical interface characteristics.

Q: Why is the 1671221 listed as obsolete?

A: The 1671221 has been superseded by the 1452987 in Phoenix Contact's product portfolio. The 1452987 maintains functional equivalence while offering active production status and ongoing inventory support.

Q: Are there packaging differences between these parts?

A: The 1671221 is specified with standard packaging, while the 1452987 is supplied in bulk packaging. This does not affect component functionality or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1671221 and 1452987 are RoHS compliant, carry MSL 1 rating, and share identical ECCN classification (EAR99).
