Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHP075052 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 7 positions at 0.200" (5.08mm) spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Connector Type & Termination: Female socket plugs with IDC termination are required to maintain interface compatibility.
• Mounting Configuration: Free hanging (in-line) orientation must be preserved for installation compatibility.
• Electrical Ratings: Voltage rating of 300V UL and wire gauge accommodation of 18-22 AWG establish the electrical operating envelope.
• Material & Compliance: UL94 V-0 flammability rating and RoHS compliance ensure regulatory and safety requirements are met.

The Phoenix Contact 1883404 satisfies all substitution criteria through matching position count, pitch, connector type, termination method, mounting style, and electrical specifications.

Engineering Selection Recommendations

The Phoenix Contact 1883404 (COMBICON QC series) is the qualified substitute for the obsolete OSTHP075052. Selection is based on the following engineering factors:

• Product Status Alignment: The 1883404 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete OSTHP075052.
• Regulatory Compliance: Both components meet UL94 V-0 flammability requirements and RoHS compliance standards, maintaining regulatory conformance in replacement applications.
• Electrical & Mechanical Specifications: Complete parameter alignment across voltage rating (300V UL), current capacity (10A), wire gauge range (18-22 AWG), and connector geometry ensures direct functional equivalence.
• Certification Alignment: Both components carry EAR99 ECCN classification and identical HTSUS codes (8536.90.4000), supporting procurement and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1883404 directly replace the OSTHP075052 in existing installations?

A: Yes. The 1883404 matches all critical substitution parameters: 7-position configuration, 0.200" (5.08mm) pitch, female socket plug type, IDC termination, free hanging mounting, 300V UL rating, and 18-22 AWG wire gauge compatibility. Mechanical and electrical interfaces are equivalent.

Q: What is the primary difference between these two parts?

A: The OSTHP075052 is obsolete with thermoplastic housing, while the 1883404 is an active product featuring polyamide (PA) nylon housing with enhanced mechanical properties. The 1883404 also includes a mating flange and tin contact finish for improved durability and contact reliability.

Q: Are there any packaging or inventory considerations?

A: The OSTHP075052 is available in limited quantities (701 pcs) as new original stock. The 1883404 is supplied in bulk packaging with higher inventory availability (1127 pcs), supporting larger procurement volumes and reducing lead times.

Q: Does the 1883404 support the same wire gauge range?

A: Yes. Both components accommodate 18-22 AWG wire gauges. The 1883404 additionally specifies 0.5-1mm² metric equivalency, providing expanded documentation for international applications.

Q: Are compliance certifications equivalent between the two parts?

A: Yes. Both components are UL94 V-0 rated, RoHS compliant, MSL 1 (unlimited moisture sensitivity), and carry identical ECCN and HTSUS classifications, ensuring regulatory equivalence in procurement and deployment.
