EDZ300/2 Equivalent & Substitute Parts

Part Overview

The EDZ300/2 is a 2-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for through-hole PCB mounting with a 45° (135°) angle 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 currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and mounting specifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

The OSTTG025100B qualifies as a substitute for the EDZ300/2 based on the following critical parameters:

• Electrical Compatibility: Both parts maintain identical current (15A) and voltage (300V) ratings, ensuring equivalent power handling capacity
• Mechanical Compatibility: Both feature 2 positions per level with 0.200" (5.08mm) pitch spacing, enabling direct PCB footprint compatibility
• Termination Method: Both utilize screw-based rising cage clamp wire termination, maintaining identical connection methodology
• Mounting Configuration: Both are through-hole mounted components with identical installation requirements
• Wire Gauge Accommodation: OSTTG025100B supports 12-24 AWG, which encompasses the EDZ300/2 range of 12-22 AWG
• Environmental Compliance: Both are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1)
• Operating Temperature: Both operate across the identical -30°C ~ 105°C temperature range

The primary difference is mating orientation: EDZ300/2 features a 45° (135°) angle, while OSTTG025100B is specified as angled. This distinction does not preclude substitution when board layout and connector positioning accommodate the alternative angle geometry.

Parameter Comparison

Engineering Selection Recommendations

Both the EDZ300/2 and OSTTG025100B are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on:

EDZ300/2 is appropriate when the specific 45° (135°) angle orientation is required by board layout constraints or connector positioning specifications.

OSTTG025100B is appropriate when the angled orientation accommodates board design requirements and the extended wire gauge range (12-24 AWG) provides additional flexibility for wire selection. The lower screw torque specification (0.4 Nm versus 0.5 Nm) may be relevant in applications where reduced clamping force is preferred.

Both parts maintain identical electrical performance across the specified voltage and current ranges, identical operating temperature performance, and equivalent termination methodology. The choice between them is determined by mechanical fit requirements and specific board layout geometry rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can OSTTG025100B directly replace EDZ300/2 in existing designs?

A: Direct replacement is possible when board layout accommodates the angled orientation of OSTTG025100B. The electrical and mechanical specifications are equivalent, and the PCB footprint spacing (0.200" pitch, 2 positions) is identical. Physical orientation and connector positioning must be verified against specific board design requirements.

Q: What is the significance of the different wire gauge ranges?

A: EDZ300/2 accommodates 12-22 AWG wire, while OSTTG025100B accommodates 12-24 AWG. The OSTTG025100B range is broader and encompasses all wire sizes supported by EDZ300/2. Both parts function identically with wires in the 12-22 AWG overlap range.

Q: How do the different screw specifications affect performance?

A: EDZ300/2 uses M2.6 screws with 0.5 Nm torque specification, while OSTTG025100B uses M2.5 screws with 0.4 Nm torque specification. These differences reflect design variations between the two terminal block series but do not affect electrical performance or current/voltage ratings. Torque specifications must be followed during assembly to ensure proper clamp force.

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

A: Yes. Both EDZ300/2 and OSTTG025100B operate across -30°C ~ 105°C, providing identical thermal performance across the full specified range.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8536.90.4000.
