EDZ300/3 Equivalent & Substitute Parts

Part Overview

The EDZ300/3 is a 3-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for through-hole PCB mounting with a 45° angled orientation. This component operates at 300V with a 15A current rating and accommodates wire gauges from 12-22 AWG using screw-based rising cage clamp termination. The part is actively produced and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable wire-to-board connections. Equivalent parts may be required due to inventory constraints, design revisions, or supply chain considerations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The OSTTG035100B qualifies as a direct substitute for the EDZ300/3 based on the following critical parameters:

Matching Parameters:

• 3 positions per level
• 0.200" (5.08mm) pitch spacing
• 15A current rating
• 300V voltage rating
• Through-hole mounting configuration
• Screw-based rising cage clamp termination
• Identical operating temperature range (-30°C ~ 105°C)
• ROHS3 compliance and REACH unaffected status

Allowable Variations:

• Mating orientation: EDZ300/3 specifies 45° (135°) angle; OSTTG035100B specifies angled orientation (compatible for general angled applications)
• Wire gauge: EDZ300/3 accepts 12-22 AWG; OSTTG035100B accepts 12-24 AWG (broader range, backward compatible)
• Housing material: EDZ300/3 uses Polyamide (PA), Nylon; OSTTG035100B uses Thermoplastic (functionally equivalent)
• Screw specifications: EDZ300/3 uses M2.6 at 0.5 Nm; OSTTG035100B uses M2.5 at 0.4 Nm (minor variation within acceptable tolerance)

Parameter Comparison

Engineering Selection Recommendations

Both the EDZ300/3 and OSTTG035100B are active products from the same manufacturer with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

EDZ300/3 Selection Criteria:

• Applications requiring specific 45° (135°) angle orientation
• Wire gauge requirements limited to 12-22 AWG range
• Designs specifying M2.6 screw specifications

OSTTG035100B Selection Criteria:

• General angled terminal block applications
• Designs accommodating 12-24 AWG wire gauge range
• Applications where M2.5 screw specifications are acceptable
• Higher inventory availability (7347 pcs vs. 959 pcs)

Both parts maintain identical electrical performance (15A, 300V), thermal operating range, and regulatory compliance, ensuring functional interchangeability within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can OSTTG035100B replace EDZ300/3 in existing designs? A: Yes, provided the PCB layout accommodates the angled orientation and the design does not require the specific 45° (135°) angle specification. The electrical and mechanical parameters are compatible.

Q: What is the difference in wire gauge acceptance? A: EDZ300/3 accepts 12-22 AWG; OSTTG035100B accepts 12-24 AWG. The OSTTG035100B accommodates a broader range, making it suitable for applications using 23-24 AWG wire.

Q: Are the screw torque specifications interchangeable? A: EDZ300/3 specifies 0.5 Nm (M2.6); OSTTG035100B specifies 0.4 Nm (M2.5). Both are within acceptable tolerance for terminal block applications. Verify torque specifications against your assembly procedures.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited), ensuring equivalent regulatory compliance.

Q: What are the housing material differences? A: EDZ300/3 uses Polyamide (PA), Nylon; OSTTG035100B uses Thermoplastic. Both materials provide equivalent mechanical and thermal performance within the specified operating range.

Q: Which part should I select for new designs? A: Selection depends on specific orientation requirements and wire gauge needs. For general applications, OSTTG035100B offers broader wire gauge compatibility and higher inventory availability.
