Substitute Part Grouping Explanation

Substitution eligibility for the OSTH412705C is determined by the following critical parameters:

Position Count & Pitch: 12 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical and electrical compatibility)
Connector Type: Plug with female sockets (required for mating with corresponding receptacles)
Termination Method: Screwless push-in spring termination (ensures compatibility with existing wire termination practices)
Mounting Configuration: Free-hanging (in-line) orientation
Voltage Rating: Minimum 300 V UL rating (meets or exceeds original specification)
Wire Gauge Compatibility: 12-26 AWG range (accommodates existing wire specifications)
Flammability & Compliance: UL94 V-0 material rating and RoHS compliance (maintains safety and regulatory standards)

The substitute part 1910623 (Phoenix Contact COMBICON FKC series) satisfies all critical substitution criteria while offering enhanced electrical performance characteristics.

Engineering Selection Recommendations

The 1910623 (Phoenix Contact COMBICON FKC series) is a direct functional equivalent to the OSTH412705C. Selection of this substitute is supported by:

Identical mechanical interface: 12-position, 5.00mm pitch configuration ensures direct replacement in existing connector receptacles
Equivalent electrical performance: 300 V UL rating and 12-26 AWG wire gauge compatibility maintain system voltage and current specifications
Matching termination architecture: Screwless push-in spring design preserves existing wire termination procedures and tooling requirements
Regulatory compliance: Both UL94 V-0 flammability rating and RoHS compliance ensure continued adherence to safety and environmental standards
Active product status: The substitute part is currently in active production with confirmed inventory availability (1043 pcs), eliminating supply chain risk associated with the obsolete original part

The substitute part provides enhanced specifications in current rating (10 A UL vs. unspecified original) and voltage rating (630 V IEC), offering improved performance margins without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Will the 1910623 plug directly into existing receptacles designed for the OSTH412705C?

A: Yes. Both parts share identical 12-position, 5.00mm pitch spacing and female socket configuration. The mechanical interface is fully compatible.

Q: Are there differences in wire termination procedures between these parts?

A: No. Both parts use identical screwless push-in spring termination. Existing wire preparation and insertion procedures apply without modification.

Q: What is the significance of the different plug wire entry angles (90° vs. 180°)?

A: The OSTH412705C features 90-degree wire entry, while the 1910623 features 180-degree wire entry. This parameter describes the angle at which wires approach the connector. Selection between these orientations depends on physical space constraints and cable routing requirements in the specific application. Both configurations are mechanically and electrically compatible with standard receptacles.

Q: Does the substitute part meet the same safety certifications?

A: Yes. Both parts carry UL94 V-0 flammability rating and RoHS compliance. The substitute meets or exceeds the original part's regulatory requirements.

Q: Is there any difference in operating temperature range?

A: The original part specifies -30°C to 105°C operating temperature. The substitute part does not provide an explicit operating temperature specification in the available data. For applications requiring confirmed temperature performance, consult Phoenix Contact technical documentation.

Q: What is the inventory status of the substitute part?

A: The 1910623 is currently in active production with 1043 pcs available in stock, ensuring reliable supply for immediate and ongoing requirements.
