TE Connectivity AMP Connectors 1776148-2 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1776148-2 is a 2 Position Terminal Block Header with male pins, shrouded on 4 sides, featuring 0.197" (5.00mm) pitch and 90° right angle orientation for through-hole mounting. This component is classified as Active product status and is designed for solder termination applications requiring electrical connectivity in industrial and commercial equipment.

Substitute parts are identified when equivalent terminal block headers share identical or compatible electrical ratings, mechanical dimensions, pitch specifications, and mounting configurations. Alternative sources become necessary due to inventory availability, supply chain considerations, or design flexibility requirements across manufacturing environments.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity AMP Connectors 1776148-2 and Phoenix Contact 1757475 maintain Active product status, ensuring continued availability and manufacturer support. Both components satisfy UL94 V-0 flammability requirements and carry RoHS compliance certifications, with the Phoenix Contact part meeting the more recent ROHS3 standard.

Electrical performance is equivalent across both parts, with identical UL current ratings of 15 A and voltage ratings of 300 V. Mechanical compatibility is confirmed through matching pitch (0.197" / 5.00mm), orientation (90° right angle), and mounting configuration (through-hole solder termination).

The Phoenix Contact 1757475 additionally provides IEC electrical ratings of 12 A at 400 V, extending operational flexibility in international applications. Both components operate across the -40°C to 110°C temperature range and maintain MSL 1 (Unlimited) moisture sensitivity classification.

Selection between these parts should be based on supply chain availability, cost considerations, and existing design documentation requirements rather than electrical or mechanical limitations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1757475 be used as a direct replacement for the TE Connectivity 1776148-2 in existing designs?

A: Yes. Both components share identical pitch (0.197" / 5.00mm), position count (2), orientation (90° right angle), mounting type (through-hole), and termination style (solder). Electrical ratings are equivalent at 15 A UL and 300 V UL. Physical footprints and PCB hole patterns are compatible.

Q: Are there dimensional differences between these two terminal block headers?

A: Minor dimensional variations exist in contact tail length and insulation height. The TE Connectivity 1776148-2 has a contact tail length of 0.126" (3.20mm) and insulation height of 0.341" (8.66mm). The Phoenix Contact 1757475 has a contact tail length of 0.138" (3.50mm) and insulation height of 0.339" (8.61mm). These variations fall within acceptable tolerances for through-hole solder applications and do not affect functional compatibility.

Q: What is the significance of the color difference between these parts?

A: The TE Connectivity 1776148-2 is black, while the Phoenix Contact 1757475 is green. Color is a cosmetic identifier and does not affect electrical performance, mechanical function, or compatibility. Color selection is typically driven by manufacturer design standards and does not impact circuit operation.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant and carry UL94 V-0 flammability ratings. The Phoenix Contact 1757475 meets the more recent ROHS3 standard, while the TE Connectivity 1776148-2 meets RoHS compliance. Both are classified as EAR99 for export control purposes and share the same HTSUS tariff code (8536.69.4040).

Q: What is the difference between UL and IEC electrical ratings?

A: UL ratings apply to North American electrical standards and safety certifications. IEC ratings apply to international standards. The Phoenix Contact 1757475 provides both UL ratings (15 A / 300 V) and IEC ratings (12 A / 400 V), offering flexibility for applications requiring international compliance. The TE Connectivity 1776148-2 provides UL ratings only.

Q: Are these components suitable for high-temperature applications?

A: Both components operate across the -40°C to 110°C temperature range. This range is suitable for industrial and commercial applications but does not extend to specialized high-temperature environments requiring ratings above 110°C.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to soldering. Standard storage conditions are acceptable.
