Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHP025052 is determined by the following critical parameters:

• Connector Type & Configuration: Must be a 2-position terminal block plug with female sockets
• Pitch Specification: Must maintain 0.200" (5.08mm) pitch spacing for mechanical and electrical compatibility
• Termination Method: Must utilize IDC (Insulation Displacement Contact) termination
• Mounting Configuration: Must support free hanging (in-line) mounting orientation
• Electrical Ratings: Must meet or exceed 300V UL voltage rating and support 18-22 AWG wire gauges
• Flammability & Safety: Must maintain UL94 V-0 material flammability rating
• Regulatory Compliance: Must comply with RoHS requirements

The substitute part 1883352 (Phoenix Contact COMBICON QC series) satisfies all critical substitution criteria while offering enhanced specifications including 10A current rating and improved contact mating finish.

Parameter Comparison

Engineering Selection Recommendations

The 1883352 (Phoenix Contact) terminal block plug is a direct functional substitute for the obsolete OSTHP025052. Both components share identical critical specifications: 2-position configuration, 5.08mm pitch, IDC termination, free hanging mounting, 300V UL rating, 18-22 AWG wire gauge support, and UL94 V-0 flammability compliance.

The substitute part offers additional advantages: active product status ensures ongoing availability and supply chain continuity, RoHS compliance meets current regulatory requirements, and enhanced specifications including 10A current rating and tin contact mating finish provide improved performance margins. The Phoenix Contact COMBICON QC series is widely used in industrial control and telecommunications applications, supporting long-term design reliability.

Frequently Asked Questions (FAQ)

Q: Can the 1883352 directly replace the OSTHP025052 in existing applications?

A: Yes. Both components maintain identical pitch spacing (5.08mm), connector type (2-position female socket plug), termination method (IDC), and electrical ratings (300V UL, 18-22 AWG). Mechanical and electrical compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The OSTHP025052 is classified as obsolete. The 1883352 is an active product with confirmed inventory availability, ensuring reliable procurement for maintenance and new designs.

Q: Are there compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements. The substitute part carries current RoHS compliance certification, while the original part is ROHS3 compliant. Both satisfy regulatory requirements for their respective product lifecycles.

Q: Does the substitute part support the same wire gauge range?

A: Yes. Both components support 18-22 AWG wire gauges. The substitute part additionally specifies 0.5-1mm² wire gauge range, providing equivalent cross-sectional area coverage.

Q: What is the difference in plug wire entry orientation?

A: The OSTHP025052 does not specify plug wire entry orientation. The 1883352 features 180° wire entry, which is a standard configuration for free hanging terminal block plugs and does not affect substitution compatibility.
