ED705/3 Equivalent & Substitute Parts

Part Overview

The ED705/3 is a 3-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 5mm pitch spacing. This component is classified as Active and is in full production. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter ranges.

Substitute Part Grouping Explanation

The ED705/3 accepts substitute part 282862-3 based on the following substitution criteria:

Critical Matching Parameters:

• Positions Per Level: 3 (exact match)
• Pitch: 0.197" (5.00mm) (exact match)
• Mating Orientation: Vertical with Board (exact match)
• Mounting Type: Through Hole (exact match)
• Wire Termination: Screw - Rising Cage Clamp (exact match)
• Screw Thread: M3 (exact match)
• Voltage Rating: 300 V (exact match)

Allowable Parameter Variations:

• Current Rating: ED705/3 rated at 15 A; 282862-3 rated at 24 A (higher rating acceptable for substitution)
• Wire Gauge: ED705/3 accepts 14-22 AWG; 282862-3 accepts 12-30 AWG (wider range acceptable for substitution)
• Housing Material: ED705/3 uses Polyamide (PA), Nylon; 282862-3 uses Polyamide (PA66), Nylon 6/6 (both polyamide-based, functionally equivalent)

Parameter Comparison

Engineering Selection Recommendations

ED705/3 (On Shore Technology Inc.): Select when ROHS3 compliance is explicitly required and REACH Unaffected status is a design constraint. Product Status is Active with established supply.

282862-3 (TE Connectivity AMP Connectors): Select when higher current capacity (24 A vs. 15 A) provides design margin or when wider wire gauge acceptance (12-30 AWG vs. 14-22 AWG) accommodates broader assembly tolerances. RoHS Compliant status meets standard environmental requirements. REACH Affected status requires verification against project-specific regulatory requirements.

Both parts maintain identical mechanical footprint, pitch, and termination method, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can 282862-3 be used as a direct replacement for ED705/3 in existing designs?

A: Yes, provided that REACH Affected status does not conflict with project requirements. Mechanical and electrical compatibility is confirmed across all critical parameters. PCB footprint and mounting hole spacing are identical.

Q: What is the significance of the higher current rating in 282862-3?

A: The 282862-3 is rated for 24 A compared to ED705/3 at 15 A. This higher rating does not create incompatibility; it provides additional thermal margin and is acceptable for circuits designed for 15 A operation.

Q: Are the wire gauge ranges interchangeable?

A: The ED705/3 accepts 14-22 AWG; the 282862-3 accepts 12-30 AWG. The 282862-3 range encompasses the ED705/3 range, making it compatible with all wire gauges specified for the original part.

Q: What is the difference between Polyamide (PA) and Polyamide (PA66)?

A: Both are polyamide-based thermoplastic materials. PA66 (Nylon 6/6) is a specific polyamide variant with enhanced thermal and mechanical properties. Both materials are functionally equivalent for this terminal block application and maintain the same operating temperature range.

Q: Does RoHS compliance differ between these parts?

A: ED705/3 is ROHS3 Compliant; 282862-3 is RoHS Compliant. Both meet RoHS requirements. ROHS3 represents a more recent compliance standard. Verify project-specific regulatory requirements before selection.

Q: What does REACH Affected vs. REACH Unaffected mean?

A: REACH Unaffected indicates the part contains no substances of concern under REACH regulations. REACH Affected indicates the part may contain regulated substances but complies with REACH requirements. Project-specific regulatory documentation should be consulted for final selection.
