Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1776299-3 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Terminal Block Type: Eurostyle Terminal Strip
• Number of Circuits: 3
• Pitch: 0.394" (10.00mm)
• Number of Rows: 2
• Number of Wire Entries: 6
• Top Termination: Screws
• Bottom Termination: Closed
• Barrier Type: Enclosed
• Mounting Type: Chassis, Panel
• Material - Insulation: Polyamide (PA66), Nylon 6/6

Allowable Parameter Variations: Substitute parts may operate within reduced electrical ratings (current and voltage) and narrower wire gauge ranges, provided the application requirements do not exceed the substitute part specifications. Operating temperature ranges may differ within the specified limits of each component.

The On Shore Technology Inc. ES1000/03DSFB satisfies all mandatory matching parameters and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology Inc. ES1000/03DSFB terminal block serves as a direct substitute for the obsolete TE Connectivity 1776299-3 when application requirements align with the reduced electrical specifications. The substitute part maintains identical mechanical form factor, pitch, circuit count, and termination method.

Electrical Derating Considerations: The ES1000/03DSFB operates at 20A maximum current and 300V maximum voltage, compared to the original part's 30A and 600V ratings. Applications requiring the full 30A or 600V specifications of the original component cannot use this substitute without design modification.

Wire Gauge Compatibility: The substitute part accepts 12-20 AWG wire, whereas the original accepts 10-22 AWG. Applications utilizing 10 AWG or 22 AWG conductors require alternative solutions.

Compliance and Manufacturing Status: The ES1000/03DSFB is an active product with ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory alignment. The original 1776299-3 is obsolete with no continued manufacturing support.

Operating Temperature Range: The substitute part supports an extended operating temperature range of -33°C to 105°C, exceeding the original part's 100°C maximum rating and providing broader environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ES1000/03DSFB replace the 1776299-3 in all applications?

A: The ES1000/03DSFB is mechanically and functionally compatible with the 1776299-3 for applications operating at or below 20A and 300V. Applications requiring 30A, 600V, or wire gauges of 10 AWG or 22 AWG must evaluate alternative solutions.

Q: What is the primary difference between these two terminal blocks?

A: The primary differences are electrical ratings and wire gauge range. The original TE Connectivity part is rated 30A/600V with 10-22 AWG capability, while the On Shore Technology substitute is rated 20A/300V with 12-20 AWG capability. All mechanical and termination characteristics are identical.

Q: Is the ES1000/03DSFB RoHS compliant?

A: Yes, the ES1000/03DSFB is ROHS3 compliant. The original 1776299-3 has RoHS status listed as not applicable due to its obsolete classification.

Q: Do these parts have the same mounting footprint?

A: Yes. Both parts feature identical pitch (0.394" / 10.00mm), circuit count (3), row configuration (2), and mounting type (Chassis, Panel), ensuring direct mechanical compatibility.

Q: What wire gauges are compatible with each part?

A: The 1776299-3 accepts 10-22 AWG wire. The ES1000/03DSFB accepts 12-20 AWG wire. Applications using 10 AWG or 22 AWG conductors require verification against the substitute part's specifications.

Q: Are there any temperature operating differences?

A: The original part operates to 100°C maximum. The substitute part operates from -33°C to 105°C, providing a wider operating range suitable for extended environmental conditions.

Q: What is the packaging difference between these parts?

A: The 1776299-3 is supplied in standard packaging. The ES1000/03DSFB is supplied in bulk packaging, which may affect procurement and inventory management processes.
