Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTTO030152 is permissible with the Weidmüller part number 1810860000 based on the following alignment of critical parameters:

• Both components feature 3 positions per level, enabling equivalent circuit connectivity
• Both utilize M2.5 screw threads with comparable torque specifications (0.4 Nm for OSTTO030152; 0.4-0.5 Nm for 1810860000)
• Both are rated for 300 V operation
• Both support through-hole PCB mounting with horizontal board orientation
• Both are classified as active products with RoHS compliance and unlimited moisture sensitivity level (MSL 1)
• Pitch specifications are within acceptable tolerance (5.00mm vs. 5.08mm), representing a 0.08mm variance typical in terminal block standardization

The substitute part accommodates a broader wire gauge range (14-28 AWG vs. 16-26 AWG) and provides higher current capacity (15 A vs. 10 A), making it suitable for applications requiring the OSTTO030152 specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTO030152 and 1810860000 maintain active product status and satisfy regulatory compliance requirements including RoHS and REACH standards. The selection between these components should be based on application-specific requirements:

The OSTTO030152 is suitable for applications with current demands up to 10 A and wire gauges between 16-26 AWG. The 1810860000 provides enhanced current capacity (15 A) and accommodates a wider wire gauge range (14-28 AWG), offering greater flexibility for applications with variable wire specifications or higher current requirements. Both components operate within the 300 V voltage specification and maintain equivalent screw torque parameters for installation consistency.

Frequently Asked Questions (FAQ)

Q: Can the 1810860000 directly replace the OSTTO030152 in existing PCB designs?

A: Direct replacement is feasible with consideration of pitch tolerance. The OSTTO030152 specifies 5.00mm pitch while the 1810860000 specifies 5.08mm pitch, representing a 0.08mm variance. PCB footprints designed for 5.00mm pitch may require minor adjustment to accommodate the 5.08mm pitch of the substitute part. Mechanical fit verification is necessary before production implementation.

Q: Are there differences in wire termination methods between these parts?

A: Yes. The OSTTO030152 uses a rising cage clamp termination mechanism, while the 1810860000 employs a clamping yoke with tension sleeve design. Both methods provide secure screw-based wire retention with comparable torque specifications (0.4 Nm vs. 0.4-0.5 Nm). The functional outcome is equivalent wire retention and electrical continuity.

Q: What is the significance of the current rating difference?

A: The OSTTO030152 is rated for 10 A maximum current, while the 1810860000 is rated for 15 A. Applications operating at or near the 10 A limit of the OSTTO030152 can safely use the 1810860000 without current-related derating concerns. Applications exceeding 10 A require the 1810860000 or equivalent higher-rated alternatives.

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

A: The OSTTO030152 specifies an operating temperature range of -30°C to 105°C. The 1810860000 does not provide an explicit operating temperature specification in the available data. Thermal performance verification is recommended for applications operating at temperature extremes.

Q: Do both parts meet the same regulatory compliance standards?

A: Both components are RoHS compliant and REACH unaffected. The OSTTO030152 carries RoHS3 certification, while the 1810860000 carries RoHS certification. Both are classified under ECCN EAR99 and HTSUS 8536.90.4000. Compliance requirements for specific end-use applications should be verified independently.
