Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1894972 is determined by the following critical parameters:

Position Configuration: Both the main part and substitute maintain 16 positions arranged in 2 levels of 8 positions each, ensuring mechanical and electrical compatibility at the connector interface level.

Connector Type & Shrouding: Both parts feature male pin headers with 4-side shrouding, maintaining identical mechanical envelope and polarization characteristics.

Termination Method: Solder termination is preserved across all parts, ensuring compatibility with existing PCB footprints and assembly processes.

Mounting Style: Vertical through-hole mounting is maintained, allowing direct replacement in existing circuit board designs.

Electrical Ratings: While pitch differs between parts (2.50mm vs. 2.54mm), the substitute part (1844934) provides equal or superior electrical performance with higher current capacity (6A vs. 4A) and maintains compliance certifications.

Compliance & Material: Both parts are RoHS compliant with polyamide housing and UL94 V-0 flammability rating, meeting regulatory requirements for industrial applications.

Engineering Selection Recommendations

The Phoenix Contact 1844934 serves as the active substitute for the obsolete 1894972. Selection of the 1844934 is supported by the following factors:

Product Status: The 1844934 maintains active product status with current manufacturing and supply chain availability, whereas the 1894972 is obsolete. For new designs and ongoing procurement, the 1844934 is the appropriate selection.

Compliance Certifications: Both parts maintain RoHS compliance and UL94 V-0 flammability rating, meeting industrial regulatory requirements. The 1844934 carries current certification status aligned with active product support.

Electrical Performance: The 1844934 provides enhanced current capacity (6A vs. 4A) across both IEC and UL standards, offering improved performance margin for applications within the original design envelope.

Mechanical Compatibility: Identical connector type, shrouding configuration, position count, and through-hole mounting ensure direct PCB footprint compatibility. The pitch difference (2.54mm vs. 2.50mm) represents a 0.04mm variance, which falls within standard PCB manufacturing tolerances for through-hole applications.

Contact Finish: The gold mating finish on the 1844934 provides enhanced corrosion resistance compared to the tin finish of the 1894972, extending component reliability in industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844934 directly replace the 1894972 in existing designs?

A: The 1844934 is mechanically and electrically compatible for direct replacement. Both parts feature identical 16-position configuration, male pin headers with 4-side shrouding, vertical through-hole mounting, and solder termination. The 0.04mm pitch difference (2.54mm vs. 2.50mm) is within standard PCB manufacturing tolerances for through-hole applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—1844934 is active while 1894972 is obsolete; (2) Pitch—1844934 uses 2.54mm standard spacing versus 1894972's 2.50mm; (3) Current rating—1844934 provides 6A versus 1894972's 4A; (4) Contact finish—1844934 features gold plating versus 1894972's tin; (5) Series designation—1844934 is COMBICON DMCV versus 1894972's MICRO-COMBICON MCDV.

Q: Are there voltage rating differences between these parts?

A: Yes. The 1894972 operates at 320V (IEC) / 125V (UL), while the 1844934 operates at 160V (IEC) / 150V (UL). For applications requiring the full 320V IEC rating, the voltage difference must be evaluated against actual system requirements.

Q: What is the significance of the contact finish difference?

A: The 1844934's gold mating finish provides superior corrosion resistance and contact reliability compared to the 1894972's tin finish. This is particularly beneficial in industrial environments with exposure to moisture or corrosive atmospheres.

Q: Is the 1844934 available in the same packaging as the 1894972?

A: The 1844934 is supplied in Cut Tape (CT) packaging, whereas the 1894972 packaging specification was not provided. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes, both the 1894972 and 1844934 are RoHS compliant with UL94 V-0 flammability rating, meeting industrial regulatory standards.
