EDZ951/3 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The EDZ951/3 is a 3-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with female sockets and 0.200" (5.08mm) pitch spacing. This component is classified as an active product with full RoHS3 compliance and operates across a temperature range of -30°C to 105°C. Alternative equivalent parts may be required due to inventory availability, specific wire gauge requirements, or application-specific performance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the EDZ951/3 is determined by the following critical parameters:

Electrical Compatibility: Voltage rating (300 V UL), pitch spacing (0.200"/5.08mm), and number of positions (3) must remain constant
Mechanical Compatibility: Mounting type (free hanging in-line), termination style (screw), and connector orientation (female sockets) must match
Material & Safety: UL94 V-0 flammability rating and RoHS3 compliance must be maintained
Wire Gauge Acceptance: Substitute parts must accept the specified wire gauge range or a compatible superset range

The OSTTJ035152 qualifies as a direct substitute based on these parameters, with allowable variations in contact material composition and wire strip length specifications.

Engineering Selection Recommendations

Both the EDZ951/3 and OSTTJ035152 are active products with full RoHS3 compliance and identical electrical and mechanical specifications for core connector functionality. Selection between these parts should be based on:

Wire Gauge Requirements: The OSTTJ035152 accepts a wider wire gauge range (12-24 AWG / 0.34-2.5mm²) compared to the EDZ951/3 (12-22 AWG / 2.5mm²). Applications requiring 24 AWG or smaller gauge wires must use OSTTJ035152
Inventory Availability: EDZ951/3 has 727 units in stock; OSTTJ035152 has 3836 units in stock
Torque Specification: OSTTJ035152 specifies slightly higher screw torque (0.56 Nm vs. 0.5 Nm). Both values remain within acceptable assembly parameters for this connector class

Both parts maintain identical voltage ratings, temperature operating ranges, flammability classifications, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can OSTTJ035152 be used as a direct replacement for EDZ951/3?

A: Yes. Both parts share identical pitch spacing (5.08mm), position count (3), mounting type (free hanging in-line), termination style (screw), voltage rating (300 V), operating temperature range (-30°C to 105°C), and flammability rating (UL94 V-0). The OSTTJ035152 accepts a superset wire gauge range, making it compatible with all applications designed for EDZ951/3.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Wire gauge acceptance range—OSTTJ035152 supports 12-24 AWG versus EDZ951/3's 12-22 AWG; (2) Contact material—EDZ951/3 uses copper contacts while OSTTJ035152 uses brass; (3) Housing material—EDZ951/3 uses polyamide (PA) nylon while OSTTJ035152 uses brass; (4) Screw torque specification—0.56 Nm for OSTTJ035152 versus 0.5 Nm for EDZ951/3; (5) Wire strip length—6mm for EDZ951/3 versus 7-8mm for OSTTJ035152.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry identical UL94 V-0 flammability ratings. Both are classified as active products with unlimited moisture sensitivity level (MSL 1).

Q: Which part should I select for new designs?

A: Selection depends on wire gauge requirements. For applications using 24 AWG wire, OSTTJ035152 is required. For applications using 12-22 AWG wire, either part is acceptable. Consider inventory availability and lead time requirements when making final selections.

Q: Is the screw torque difference significant?

A: The torque difference (0.5 Nm vs. 0.56 Nm) is minor and both values fall within standard assembly parameters for this connector class. No special handling is required when switching between parts.
