Phoenix Contact 1680940 Sensor Actuator Box - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1680940 is a sensor actuator box designed for M12 circular connector applications with 4 connector openings and 4 positions. This component provides dust-tight and waterproof protection for sensor and transducer installations. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new installations where this specific model is no longer available from the manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1680940 is determined by the following critical parameters:

• Shell Size - Insert: M12 (must match for mechanical compatibility)
• Connector Openings: 4 (functional requirement)
• Positions: 4 (functional requirement)
• Features: Dust Tight, Waterproof (environmental protection requirements)
• Accessory Type: Actuator Box (functional classification)
• For Use With/Related Products: Circular Connectors (application compatibility)

Both substitute parts meet these core requirements. The primary differences lie in material composition, color, product status, and RoHS certification level, which do not affect the core substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products from Phoenix Contact and provide functional equivalence to the obsolete 1680940 model.

Part 1516962 is the primary substitute. It maintains identical series designation (PLUSCON), color (green), and RoHS compliance level to the original part. The material change from polyamide to PBT does not affect the core substitution criteria, as both materials meet the dust-tight and waterproof requirements specified for M12 circular connector applications.

Part 1452398 is an alternative substitute with active product status and ROHS3 compliance. The material composition (PBT) and color (black) differ from the original, but all functional parameters for M12 actuator box applications remain equivalent. This part is suitable where color differentiation is not a system requirement.

Both parts carry identical REACH and ECCN classifications, confirming regulatory equivalence for the intended application.

Frequently Asked Questions (FAQ)

Q: Can part 1452398 be used in place of 1680940 despite the color difference?

A: Yes. Color is not a substitution criterion for this component category. The functional parameters—M12 shell size, 4 connector openings, 4 positions, dust-tight and waterproof features—are identical across all three parts.

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

A: Both polyamide and polybutylene terephthalate (PBT) are engineering polymers suitable for M12 actuator box applications with dust-tight and waterproof protection. The material change does not affect the core substitution criteria for this product category.

Q: Why is 1516962 preferred over 1452398?

A: Part 1516962 maintains the PLUSCON series designation and green color of the original 1680940, providing closer visual and series alignment. However, both parts are functionally equivalent for M12 circular connector applications.

Q: Are there any compliance differences between the substitutes?

A: Both substitutes are REACH Unaffected and carry EAR99 ECCN classification, matching the original part. Part 1516962 maintains RoHS compliance; part 1452398 carries ROHS3 compliance. Both certifications are acceptable for this component category.

Q: What is the MSL rating and why does it matter?

A: Both the original and substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This specification is consistent across all three parts.
