Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH416705A is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 16 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical fit)
• Connector Type: Plug configuration with female sockets
• Mounting Configuration: Free-hanging in-line orientation
• Termination Method: Screwless push-in spring technology
• Electrical Ratings: Minimum 300V UL compliance and support for 12-26 AWG wire gauges
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1974876 qualifies as a direct substitute based on these parameters. While the 1974876 exhibits enhanced electrical specifications (630V IEC, 12A IEC current rating) and additional certifications, it maintains full backward compatibility with the OSTH416705A across all critical mechanical and electrical interfaces.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1974876 serves as the primary equivalent for the obsolete OSTH416705A. Selection should be based on the following engineering criteria:

Product Status Consideration: The OSTH416705A is classified as obsolete, whereas the 1974876 maintains active product status with current manufacturing support and documented availability (897 pcs in stock).

Compliance & Certification: Both components satisfy UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The 1974876 carries full RoHS compliance, meeting modern regulatory requirements for new designs and system upgrades.

Electrical Performance: The 1974876 provides enhanced electrical specifications (630V IEC, 12A IEC) while maintaining full compatibility with the 300V UL requirement of the original design. This represents a performance upgrade without introducing incompatibility.

Mechanical Compatibility: Wire entry orientation differs (90° vs. 180°). This distinction requires physical space assessment during installation but does not affect electrical or functional compatibility. Both configurations support identical wire gauge ranges (12-26 AWG) and utilize identical push-in spring termination methodology.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1974876 directly replace the OSTH416705A in existing installations?

A: Yes, the 1974876 is mechanically and electrically compatible. The primary consideration is wire entry orientation: the OSTH416705A features 90° entry while the 1974876 provides 180° entry. Physical space constraints in the installation must be evaluated to confirm the 180° configuration is acceptable.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution requires matching: 16-position count, 0.197" (5.00mm) pitch spacing, plug configuration with female sockets, free-hanging in-line mounting, screwless push-in spring termination, and minimum 300V UL electrical rating with 12-26 AWG wire support.

Q: Does the 1974876 offer any performance advantages over the OSTH416705A?

A: The 1974876 provides enhanced IEC electrical ratings (630V, 12A) and explicit current specifications (10A UL) not documented for the original part. Both components meet identical flammability and moisture sensitivity requirements.

Q: Are there packaging differences between these components?

A: The OSTH416705A packaging is not specified in available documentation. The 1974876 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: What is the significance of the different wire entry angles?

A: The 90° entry on the OSTH416705A and 180° entry on the 1974876 affect physical installation orientation but not electrical function. Evaluate available space in your application to confirm the 180° configuration accommodates your wiring layout.
