Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH409705B is determined by the following critical parameters:

Position and Pitch Compatibility: The substitute must maintain 9 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Termination Technology: Push-in spring termination (screwless) is required to match the original connection method and installation procedure.

Electrical Ratings: The substitute must meet or exceed the 300V UL voltage specification and support 12-26 AWG wire gauges to maintain system safety margins and wire compatibility.

Mounting Configuration: Free-hanging in-line mounting is mandatory to preserve the original form factor and installation orientation.

Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating ensure regulatory alignment and material safety requirements.

The Phoenix Contact 1910429 satisfies all substitution criteria through identical position count, pitch spacing, termination method, voltage rating, wire gauge range, mounting type, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910429 is the qualified substitute for the obsolete OSTH409705B. Both components maintain identical electrical and mechanical specifications across all critical parameters: 9-position configuration, 5.00mm pitch, push-in spring termination, 300V UL rating, and 12-26 AWG wire compatibility.

The primary distinction is product status: the OSTH409705B is obsolete, while the 1910429 maintains active production status, ensuring long-term availability and supply chain continuity. Both components satisfy RoHS3 compliance and UL94 V-0 flammability requirements, confirming regulatory alignment for new designs and legacy system replacements.

The 1910429 provides enhanced specifications in areas not limiting substitution: higher IEC current rating (12A versus unspecified), higher IEC voltage rating (630V versus unspecified), expanded wire gauge range in metric units (0.2-2.5mm²), defined wire strip length (10mm), and specified insulation height (15.00mm). These enhancements do not restrict compatibility and provide additional design margin.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910429 directly replace the OSTH409705B in existing installations?

A: Yes. Both components share identical position count (9), pitch spacing (5.00mm), termination method (push-in spring), mounting type (free-hanging in-line), voltage rating (300V UL), and wire gauge range (12-26 AWG). Mechanical and electrical compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The OSTH409705B is classified as obsolete. The Phoenix Contact 1910429 is an active production component, ensuring availability for replacement stock and new system designs.

Q: Are there compliance or safety differences between these parts?

A: No. Both components are RoHS3 compliant and carry UL94 V-0 flammability ratings. Regulatory and safety requirements are equivalent.

Q: Does the 1910429 support the same wire gauges?

A: Yes. Both components accept 12-26 AWG wire. The 1910429 additionally specifies metric equivalents (0.2-2.5mm²) for international applications.

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

A: The OSTH409705B specifies 270° orientation, while the 1910429 specifies 180° orientation. This difference reflects the physical wire entry angle but does not affect electrical or mechanical compatibility with standard mating connectors, as both are free-hanging in-line configurations.

Q: Are there inventory considerations?

A: The OSTH409705B has 787 pieces in stock (obsolete status). The 1910429 has 1033 pieces in stock with active production status, providing superior long-term supply assurance.
