OSTOQ247150 Equivalent & Substitute Parts

Part Overview

The OSTOQ247150 is a 24-position terminal block header manufactured by On Shore Technology Inc. This component features male pins with 4-side shrouding, a 5.00mm pitch, and vertical solder mounting configuration. The part is currently active in production with 635 units in stock. Terminal block headers of this specification are essential interconnection components in industrial control systems, power distribution modules, and signal routing applications where reliable multi-position connections are required. Equivalent and substitute parts may be necessary due to supply chain considerations, lead time requirements, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOQ247150 is determined by the following critical parameters:

Position Count & Pitch Compatibility: The substitute part must maintain 24 positions with a pitch specification within the allowed tolerance range. The OSTOQ247150 operates at 5.00mm pitch; the substitute part 1755956 operates at 5.08mm pitch, representing a 0.08mm variance that falls within standard mechanical tolerance for terminal block interconnection systems.

Connector Type & Shrouding: Both parts must be header-type connectors with male pins and 4-side shrouding to ensure mechanical and electrical compatibility with mating receptacles.

Orientation & Mounting: Vertical orientation is maintained in the substitute part. The OSTOQ247150 uses solder mounting, while the substitute uses through-hole mounting; both are PCB-level termination methods suitable for equivalent circuit board integration.

Electrical Ratings: The substitute part meets or exceeds the UL voltage rating of 300V specified for the main part. The substitute provides additional current rating (12A IEC) not specified in the main part documentation.

Compliance & Environmental: Both parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTOQ247150 and 1755956 maintain active product status with full ROHS3 compliance and unlimited moisture sensitivity ratings, confirming regulatory and environmental equivalence.

The primary distinction between these parts is the mounting method: the OSTOQ247150 uses solder termination while the 1755956 uses through-hole termination. Both methods provide equivalent PCB-level integration for 24-position interconnection applications.

The pitch variance of 0.08mm (5.00mm versus 5.08mm) represents a standard tolerance range within terminal block connector specifications. This minor dimensional difference does not affect electrical performance or mating compatibility with standard 5mm-pitch receptacle systems.

The substitute part 1755956 provides additional electrical specifications including 12A current rating (IEC) and 630V voltage rating (IEC), which exceed the UL 300V specification of the main part. These enhanced ratings do not create incompatibility; they indicate broader application suitability.

Selection between these parts should be based on mounting method requirements: solder mounting for the OSTOQ247150 or through-hole mounting for the 1755956, depending on PCB design and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1755956 directly replace the OSTOQ247150 in existing designs?

A: Direct replacement depends on mounting method compatibility. The OSTOQ247150 requires solder termination pads, while the 1755956 requires through-hole vias. PCB layout modifications are necessary if switching between these mounting types. The 0.08mm pitch variance is within standard tolerance for terminal block systems.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm difference represents a standard tolerance range in terminal block connector specifications. Both pitches are compatible with 5mm-class receptacle systems and do not affect electrical performance or signal integrity.

Q: Are the electrical ratings of the 1755956 compatible with OSTOQ247150 applications?

A: Yes. The 1755956 meets the UL 300V specification of the OSTOQ247150 and provides additional IEC ratings (12A, 630V) that do not create incompatibility. Enhanced ratings indicate broader application capability.

Q: What are the housing material differences and their implications?

A: The OSTOQ247150 uses thermoplastic housing while the 1755956 uses polyamide (PA) nylon. Both materials provide equivalent electrical insulation and mechanical protection for terminal block applications. Material selection does not affect functional compatibility.

Q: How do the contact tail lengths differ between these parts?

A: The OSTOQ247150 has a 4.00mm contact tail length while the 1755956 has a 3.90mm contact tail length. This 0.10mm difference is within standard manufacturing tolerance and does not affect solder joint quality or electrical connection reliability.

Q: What is the significance of the insulation height difference?

A: The OSTOQ247150 has 4.00mm insulation height while the 1755956 has 12.00mm insulation height. The increased insulation height in the 1755956 provides additional creepage distance and clearance, which is beneficial for high-voltage applications but does not create incompatibility with standard 5mm-pitch receptacles.

Q: Are both parts suitable for the same operating temperature range?

A: The OSTOQ247150 specifies -30°C to 105°C operating temperature. The 1755956 does not provide explicit operating temperature specification in the available documentation. For applications requiring confirmed temperature range compatibility, the OSTOQ247150 specification should be referenced.

Q: Do both parts maintain equivalent compliance certifications?

A: Yes. Both parts are ROHS3 compliant, maintain MSL 1 (unlimited) moisture sensitivity rating, and are REACH unaffected, confirming regulatory and environmental equivalence for industrial applications.
