OSTTO050152 Equivalent & Substitute Parts

Part Overview

The OSTTO050152 is a 5-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 5.00mm pitch spacing. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different pitch tolerances and position configurations within the terminal block category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTO050152 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (10 A minimum), voltage rating (300 V minimum), and wire gauge acceptance range must accommodate the original specification
• Mechanical Compatibility: Through-hole mounting type, horizontal board orientation, and screw-based wire termination method must be maintained
• Pitch Tolerance: Pitch spacing of 5.00mm (0.197") to 5.08mm (0.200") falls within acceptable mechanical tolerance for PCB layout compatibility
• Regulatory Compliance: RoHS3 compliance and MSL rating of 1 (Unlimited) must be preserved
• Position Configuration: While position count may vary (5 to 6 positions), the per-level configuration and interlocking side-entry design must remain consistent

The substitute part 1989405 (Phoenix Contact COMBICON MKDSN series) meets these criteria with equivalent electrical ratings, compatible mounting methodology, and compliant regulatory status.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTO050152 and 1989405 maintain Active product status with full RoHS3 compliance and MSL rating of 1 (Unlimited), ensuring long-term availability and regulatory alignment. The electrical specifications are equivalent at 10 A current and 300 V voltage ratings. The primary design consideration is the pitch differential of 0.08mm (5.00mm versus 5.08mm) and position count increase from 5 to 6. PCB layout verification is required to confirm that the 5.08mm pitch spacing accommodates existing through-hole footprints. The 1989405 accepts a broader wire gauge range (12-30 AWG versus 16-26 AWG), providing additional flexibility for conductor sizing. Both components utilize identical screw-based rising cage clamp termination and side-entry interlocking design, ensuring functional compatibility in wire-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the 1989405 directly replace the OSTTO050152 on existing PCBs?

A: Direct replacement requires PCB footprint verification. The pitch difference of 0.08mm (5.00mm to 5.08mm) and increased position count (5 to 6) necessitate layout confirmation. If the PCB is designed with tolerance for 5.08mm pitch spacing and has available space for the additional position, substitution is mechanically feasible.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated for 10 A current and 300 V voltage. The 1989405 accepts a wider wire gauge range (12-30 AWG) compared to the OSTTO050152 (16-26 AWG), providing greater conductor compatibility.

Q: What is the significance of the pitch tolerance difference?

A: The 0.08mm pitch difference (0.197" versus 0.200") is within typical PCB manufacturing tolerances but requires verification against the specific board design. This difference may affect through-hole alignment and should be confirmed during component selection.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the OSTTO050152 and 1989405 are RoHS3 compliant with MSL rating 1 (Unlimited), meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the impact of the position count difference?

A: The 1989405 provides 6 positions per level versus 5 for the OSTTO050152. This additional position increases circuit connection capacity but requires PCB layout accommodation. The substitute is suitable only if the application can utilize or accommodate the extra position.

Q: Are the screw specifications compatible?

A: Both components use screw-based rising cage clamp termination. The OSTTO050152 specifies M2.5 screws with 0.4 Nm torque, while the 1989405 uses M3 screws with 0.5-0.6 Nm torque. Different torque specifications require tool adjustment during installation.
