TE Connectivity 3-1564526-1 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-1564526-1 is an 18-position rectangular connector plug housing from the Heavy Duty Sealed Connector Series (MCP 1.5K). This component serves as the housing assembly for sealed rectangular connectors in panel-mount applications requiring crimp termination. The part is actively manufactured and maintained in production status. Substitute parts are identified to provide alternative options based on parametric equivalence, particularly when specific color variants or inventory availability require component selection from equivalent housing designs within the same connector series.

Substitute Part Grouping Explanation

Substitute parts for the 3-1564526-1 are identified based on strict parametric equivalence within the Heavy Duty Sealed Connector Series (MCP 1.5K). The substitution logic is based on the following critical parameters that must remain constant:

• Connector Type: Plug housing configuration
• Number of Positions: 18-position layout
• Pitch and Row Spacing: 0.157" (4.00mm) pitch with 0.236" (6.00mm) row spacing
• Mounting Type: Panel mount with mounting flange
• Contact Termination: Crimp-style termination
• Fastening Type: Slide-on fastening mechanism
• Insulation Material: PBT, glass-filled construction
• Operating Temperature Range: -40°C to 140°C
• Sealed Features: Sealed connector design
• Compliance: RoHS compliant, MSL 1

The identified substitute part differs only in color designation (Black versus Green), which does not affect electrical or mechanical compatibility. Both parts share the same base product number (1564526) and series classification, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the 3-1564526-1 and 1-1564526-1 are active production parts manufactured by TE Connectivity and maintain full RoHS compliance with MSL 1 rating. Selection between these parts is determined by application-specific color requirements and inventory availability.

The 3-1564526-1 (Green) is suitable for applications where color coding or visual identification requires green housing designation. The 1-1564526-1 (Black) provides equivalent functionality with black housing for applications requiring alternative color identification.

Both parts are certified for identical electrical and mechanical performance across the full operating temperature range of -40°C to 140°C. The sealed connector design and crimp termination method are consistent across both variants. Selection should be based on documented color requirements in the application schematic or assembly specification.

Frequently Asked Questions (FAQ)

Q: Are the 3-1564526-1 and 1-1564526-1 electrically interchangeable?

A: Yes. Both parts are 18-position plug housings with identical electrical specifications, including pitch (0.157"/4.00mm), row spacing (0.236"/6.00mm), contact termination method (crimp), and operating temperature range (-40°C to 140°C). The only difference is the color designation.

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

A: Color serves as a visual identifier for connector type or circuit function in system design. The 3-1564526-1 uses green housing, while the 1-1564526-1 uses black housing. Selection depends on the color-coding requirements specified in the application documentation.

Q: Can I use the 1-1564526-1 (Black) as a direct replacement for the 3-1564526-1 (Green)?

A: Direct replacement is possible only if the application does not require specific color identification. If color coding is a functional requirement for system assembly or maintenance procedures, the specified color variant must be used.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3-1564526-1 and 1-1564526-1 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the mounting configuration for these connector housings?

A: Both parts are panel-mount rectangular connectors with mounting flanges and slide-on fastening mechanisms. They are designed for crimp-style contact termination.

Q: Do these housings include contacts?

A: No. Both the 3-1564526-1 and 1-1564526-1 are housing assemblies only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What is the base product number for these parts?

A: Both parts share the base product number 1564526, confirming they are variants within the same product family within the Heavy Duty Sealed Connector Series (MCP 1.5K).
