ED300/3 Terminal Block Equivalent & Substitute Parts

Part Overview

The ED300/3 is a 3-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for PCB mounting with a 45° angled mating orientation and 5.00mm pitch. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer offerings or product series variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED300/3 is determined by the following critical parameters:

Mandatory Matching Criteria:

• 3 positions per level
• 0.197" (5.00mm) pitch spacing
• Through-hole PCB mounting
• Screw-based wire termination with rising cage clamp mechanism
• 300 V voltage rating
• RoHS3 compliance status

Allowable Variation Parameters:

• Mating orientation angle (45°, 35°, or angled configurations)
• Wire gauge acceptance range (12-22 AWG minimum, up to 12-30 AWG acceptable)
• Current rating (minimum 15 A; higher ratings acceptable)
• Housing material composition (polyamide, thermoplastic, nylon variants)
• Contact and clamp plating materials (brass, tin-plated, nickel-plated options)
• Screw specifications (M2.5, M2.6, M3 threads; torque variations 0.4-0.79 Nm)

Parameter Comparison

Engineering Selection Recommendations

OSTTG030160B (On Shore Technology Inc.): This substitute maintains identical electrical specifications (15 A, 300 V) and pitch geometry (5.00mm). Both components are manufactured by On Shore Technology Inc. and carry RoHS3 compliance. The OSTTG030160B accepts a broader wire gauge range (12-24 AWG vs. 12-22 AWG) and features thermoplastic housing. Mating orientation is specified as "Angled" rather than the specific 45° angle of the ED300/3. This part is suitable for applications where the exact angle specification is not critical to PCB layout constraints.

796690-3 (TE Connectivity AMP Connectors): This substitute provides higher current capacity (17.5 A vs. 15 A) and extended wire gauge acceptance (12-30 AWG). The 35° mating angle differs from the ED300/3's 45° specification. Contact and clamp materials feature tin plating, and screw specifications differ (M3 thread, 0.79 Nm torque vs. M2.6 thread, 0.5 Nm torque on the main part). RoHS compliance is confirmed; however, operating temperature range is not specified. This part is applicable where higher current capacity is beneficial and PCB layout accommodates the 35° angle orientation.

Frequently Asked Questions (FAQ)

Q: Can OSTTG030160B replace ED300/3 in all applications? A: OSTTG030160B meets the core electrical and mechanical requirements (3 positions, 5.00mm pitch, 15 A, 300 V, through-hole mounting, screw termination). The primary difference is mating orientation specification. If your PCB layout requires the specific 45° angle of the ED300/3, verify that the "Angled" specification of OSTTG030160B is compatible with your design constraints.

Q: What are the implications of using 796690-3 instead of ED300/3? A: The 796690-3 maintains pitch, position count, voltage, and termination method. Key differences include: (1) higher current rating (17.5 A vs. 15 A), which is acceptable for ED300/3 applications; (2) different mating angle (35° vs. 45°), requiring PCB layout verification; (3) different screw specifications (M3 vs. M2.6), which may affect installation torque procedures; (4) unspecified operating temperature range, whereas ED300/3 specifies -30°C ~ 105°C.

Q: Are all three parts interchangeable on the same PCB? A: Electrical interchangeability is confirmed across all three parts for standard 15 A applications. Mechanical interchangeability depends on PCB hole spacing (all use 5.00mm pitch) and mounting angle tolerance. The ED300/3 and 796690-3 have defined angle specifications (45° and 35° respectively), while OSTTG030160B is specified as "Angled." Verify your PCB layout accommodates the specific orientation of your selected substitute.

Q: What compliance certifications apply to all substitute options? A: All three parts carry RoHS compliance (ED300/3 and OSTTG030160B are RoHS3 Compliant; 796690-3 is RoHS Compliant). All parts have MSL rating of 1 (Unlimited moisture sensitivity). REACH status is either "REACH Unaffected" or "Vendor Undefined" across the options. ECCN classification is EAR99 for all parts.

Q: Does wire gauge acceptance affect substitution suitability? A: Wire gauge ranges are 12-22 AWG (ED300/3), 12-24 AWG (OSTTG030160B), and 12-30 AWG (796690-3). If your application uses wire gauges between 22-24 AWG, only OSTTG030160B and 796690-3 are suitable. If wire gauges exceed 24 AWG, only 796690-3 is rated. For standard 12-22 AWG applications, all three parts are acceptable.
