OSTH413705D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH413705D is a 13-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within a temperature range of -30°C to 105°C and supports wire gauges from 12-26 AWG with a rated voltage of 300V UL.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH413705D is determined by strict alignment of the following critical parameters:

Position Count & Pitch: Substitute must maintain 13 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors
Connector Type: Female socket configuration required for direct replacement in existing harnesses
Termination Method: Screwless push-in spring termination ensures compatibility with wire insertion procedures
Mounting Configuration: Free hanging (in-line) orientation required for identical installation geometry
Wire Gauge Compatibility: Support for 12-26 AWG wire range maintains electrical performance across the specified conductor sizes
Voltage Rating: Minimum 300V UL rating required to meet or exceed original specification
Flammability & Compliance: UL94 V-0 material rating and RoHS compliance ensure regulatory equivalence

The Phoenix Contact 1910636 qualifies as a direct substitute based on these parameters. While the 1910636 features a 180° wire entry orientation (compared to the original 270°), this represents a geometric variation that does not affect electrical or mechanical compatibility when the connector is repositioned within the assembly. Both parts share identical position count, pitch, termination style, mounting type, wire gauge range, and compliance certifications.

Engineering Selection Recommendations

The Phoenix Contact 1910636 is the qualified substitute for the obsolete OSTH413705D based on the following engineering criteria:

Compliance & Regulatory Status: The 1910636 maintains RoHS compliance and UL94 V-0 flammability rating, ensuring equivalence to the original part's regulatory standing. As an active production component from a major connector manufacturer, the 1910636 provides long-term supply chain stability compared to the obsolete OSTH413705D.

Electrical & Mechanical Equivalence: Both parts share identical electrical specifications (300V UL, 12-26 AWG wire gauge support) and mechanical configuration (13 positions, 5.00mm pitch, push-in spring termination). The difference in wire entry angle (180° vs. 270°) is a geometric consideration that does not affect electrical performance or contact integrity.

Supply Chain Continuity: With 1032 units in stock and active manufacturing status, the 1910636 provides immediate availability and long-term procurement reliability for replacement and new design applications.

Frequently Asked Questions (FAQ)

Q: Can the 1910636 directly replace the OSTH413705D in existing assemblies?

A: Yes. Both connectors share identical electrical ratings, position count, pitch spacing, and termination method. The wire entry angle difference (180° vs. 270°) is a geometric variation that does not affect electrical compatibility. Physical installation may require connector repositioning within the assembly to accommodate the different wire entry orientation.

Q: Are there any voltage or current limitations when substituting to the 1910636?

A: No. The 1910636 meets or exceeds the original specification with a 300V UL rating and 10A UL current rating. Wire gauge compatibility remains identical at 12-26 AWG.

Q: Does the 1910636 support the same operating temperature range?

A: The OSTH413705D specifies -30°C to 105°C operation. The 1910636 operating temperature is not provided in the available data. Verify temperature requirements against your specific application before final selection.

Q: What is the significance of the wire entry angle difference?

A: The 270° orientation of the OSTH413705D and 180° orientation of the 1910636 describe the angle at which wires enter the connector housing. This is a physical/geometric characteristic that affects assembly orientation but does not impact electrical performance or contact function.

Q: Are both parts RoHS compliant?

A: Yes. The OSTH413705D is ROHS3 compliant, and the 1910636 is RoHS compliant. Both meet current environmental and regulatory requirements.

Q: What packaging is available for the 1910636?

A: The 1910636 is supplied in bulk packaging with 1032 units currently in stock.
