OSTVD203152 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTVD203152 is a 20-position terminal block plug manufactured by On-Shore Technology, featuring female sockets with 0.150" (3.81mm) pitch spacing and 180° free-hanging in-line mounting. This component is designed for screw-terminated electrical connections in industrial and control applications. The part is currently active in production with 1073 units in stock.

Substitute parts are identified when equivalent terminal block plugs meet the same electrical specifications, mechanical dimensions, and compliance requirements, enabling direct replacement in applications where the original part becomes unavailable or when inventory optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVD203152 is determined by strict alignment of the following critical parameters:

Electrical Compatibility: Current rating of 8 A (UL), voltage rating of 300 V (UL), and wire gauge range of 16-28 AWG establish the electrical load capacity. Substitute parts must meet or exceed these specifications.

Mechanical Compatibility: 20-position configuration, 0.150" (3.81mm) pitch spacing, 180° wire entry orientation, and free-hanging in-line mounting ensure physical and functional interchangeability. The M2 screw size and torque specification (0.2 Nm) define the termination interface.

Compliance & Safety: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status are mandatory for equivalent substitution in regulated applications.

Dimensional Tolerance: Insulation height of 0.433" (11.00mm) and wire strip length of 6-7mm must be maintained for proper mating with corresponding receptacle connectors.

The Phoenix Contact 1840353 qualifies as a substitute based on matching all critical parameters within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTVD203152 and 1840353 are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for regulated industrial applications. The Phoenix Contact 1840353 offers a wider wire gauge acceptance range (14-30 AWG versus 16-28 AWG), providing greater flexibility for applications with smaller or larger conductor sizes. The rising cage clamp termination mechanism in the 1840353 represents a design variation that maintains electrical and mechanical compatibility while offering alternative clamping characteristics. Both parts maintain equivalent insulation height and screw interface specifications within standard engineering tolerances. Selection between these parts should be based on application-specific requirements, inventory availability, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1840353 directly replace the OSTVD203152 in existing installations?

A: Yes. Both parts share identical 20-position configuration, 0.150" (3.81mm) pitch, 180° wire entry, and free-hanging mounting. Electrical ratings (8 A, 300 V UL) and safety certifications (UL94 V-0, ROHS3) are equivalent. The rising cage clamp termination in the 1840353 is functionally compatible with standard screw termination applications.

Q: What is the significance of the wire gauge range difference?

A: The OSTVD203152 accepts 16-28 AWG wire, while the 1840353 accepts 14-30 AWG. The 1840353 provides broader compatibility with both smaller (14 AWG) and larger (30 AWG) conductors. For applications using wire within the 16-28 AWG range, both parts are interchangeable.

Q: Are there dimensional differences that affect mating with receptacle connectors?

A: Insulation height differs by 0.004" (0.10mm): OSTVD203152 at 0.433" (11.00mm) and 1840353 at 0.437" (11.10mm). This variation is within standard mechanical tolerances and does not prevent proper mating with standard COMBICON or equivalent receptacle connectors designed for 3.81mm pitch terminal blocks.

Q: Do the screw torque specifications differ significantly?

A: The OSTVD203152 specifies 0.2 Nm (1.7 Lb-In), while the 1840353 specifies 0.22-0.25 Nm (1.9-2.2 Lb-In). Both values are within acceptable engineering tolerance for M2 screw termination. The 1840353 torque range provides a slightly higher clamping force, which is compatible with standard installation practices.

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

A: The OSTVD203152 specifies -30°C to 105°C operating temperature. The 1840353 does not provide an explicit operating temperature specification in the available data. For applications requiring confirmed temperature performance, the OSTVD203152 specification should be referenced.

Q: What compliance certifications apply to both parts?

A: Both the OSTVD203152 and 1840353 are ROHS3 compliant and REACH unaffected. Both carry UL94 V-0 flammability ratings. These certifications ensure suitability for regulated industrial, control, and safety-critical applications.
