OSTKQ166200 Equivalent & Substitute Parts

Part Overview

The OSTKQ166200 is a 16-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal mounting with 0.400" (10.16mm) pitch spacing. This component features screw-based rising cage clamp termination and is rated for 57 A at 300 V, accommodating wire gauges from 6-22 AWG.

The OSTKQ166200 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure procurement availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTKQ166200 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (57 A), voltage rating (300 V), and wire gauge acceptance range must meet or exceed the original specification
• Mechanical Compatibility: 16 positions, 0.400" (10.16mm) pitch, horizontal board orientation, through-hole mounting, and screw-based termination method
• Environmental Compliance: Operating temperature range (-40°C ~ 115°C), RoHS3 compliance, and MSL rating (1 - Unlimited)
• Termination Method: Rising cage clamp screw termination is required for functional equivalence

The A-TB116-VP16 from Assmann WSW Components meets all critical substitution criteria. This part maintains identical position count, pitch spacing, mating orientation, current and voltage ratings, mounting method, and termination technology. The substitute part is classified as active product status, ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The A-TB116-VP16 is the qualified substitute for the OSTKQ166200. Both components maintain ROHS3 compliance and identical MSL ratings (1 - Unlimited), ensuring regulatory and environmental compatibility.

The primary design consideration is the wire gauge range difference: the OSTKQ166200 accepts 6-22 AWG, while the A-TB116-VP16 accepts 8-22 AWG. Applications utilizing wire gauges smaller than 8 AWG require design review to confirm compatibility with the substitute part.

The A-TB116-VP16 is actively manufactured and stocked, providing supply chain continuity for the obsolete OSTKQ166200.

Frequently Asked Questions (FAQ)

Q: Can the A-TB116-VP16 be used as a direct replacement for the OSTKQ166200?

A: Yes, for applications using wire gauges 8-22 AWG. The electrical ratings (57 A, 300 V), mechanical configuration (16 positions, 10.16mm pitch), mounting method (through-hole), and termination technology (screw rising cage clamp) are identical. Applications requiring 6-7 AWG wire gauge compatibility require alternative evaluation.

Q: What is the primary difference between these two parts?

A: The OSTKQ166200 is obsolete, while the A-TB116-VP16 is an active product. The A-TB116-VP16 has a narrower wire gauge acceptance range (8-22 AWG versus 6-22 AWG). All other electrical, mechanical, and environmental specifications are equivalent.

Q: Are there packaging differences between these parts?

A: The OSTKQ166200 packaging is not specified in the technical data. The A-TB116-VP16 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OSTKQ166200 and A-TB116-VP16 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What screw specifications apply to the A-TB116-VP16?

A: The A-TB116-VP16 uses M4.5 screw thread with a torque specification of 2.15 Nm (19 Lb-In). The original OSTKQ166200 specifies 1.18 Nm (10.4 Lb-In) torque. Verify torque application procedures with assembly documentation.
