TE Connectivity 4-1564546-1 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-1564546-1 is a 2-position rectangular connector plug housing from the Heavy Duty Sealed Connector Series, MCP 6.3. This component is a panel-mount plug housing with a 0.354" (9.00mm) pitch, designed for crimp contact termination with slide-on fastening. The housing features a sealed design with a mounting flange and is constructed from glass-filled polybutylene terephthalate (PBT) material. The part is currently active in production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when specific color variants are required for application-specific identification, inventory management, or when the primary part becomes unavailable while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4-1564546-1 are determined by strict adherence to the following critical parameters:

Electrical and Mechanical Compatibility Criteria:

• Connector Type: Plug
• Number of Positions: 2
• Pitch: 0.354" (9.00mm)
• Number of Rows: 1
• Contact Type: Tab
• Mounting Type: Panel Mount
• Contact Termination: Crimp
• Fastening Type: Slide-On
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -40°C to 140°C
• Features: Mounting Flange, Sealed
• Series: Heavy Duty Sealed Connector Series, MCP 6.3

The substitute parts 1-1564546-1 and 2-1564546-1 maintain identical electrical and mechanical specifications to the main part. The only variable parameter is the housing color (Blue, Black, or Gray), which does not affect functional compatibility or performance characteristics. All substitute parts share the same base product number (1564546) and are manufactured by TE Connectivity AMP Connectors within the same product series.

Parameter Comparison

Engineering Selection Recommendations

All three connector plug housing variants (4-1564546-1, 1-1564546-1, and 2-1564546-1) are functionally equivalent for applications requiring a 2-position rectangular connector plug housing with 9.00mm pitch within the Heavy Duty Sealed Connector Series, MCP 6.3.

Compliance Status:

• 4-1564546-1: RoHS Compliant
• 1-1564546-1: ROHS3 Compliant
• 2-1564546-1: ROHS3 Compliant

All parts maintain active production status and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Selection Basis: Component selection should be based on application-specific requirements for housing color identification or current inventory availability. The black variant (1-1564546-1) and gray variant (2-1564546-1) offer higher current stock levels compared to the blue variant (4-1564546-1). All parts are manufactured by TE Connectivity AMP Connectors and share identical electrical performance, mechanical dimensions, and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically and mechanically interchangeable with the 4-1564546-1?

A: Yes. The substitute parts 1-1564546-1 and 2-1564546-1 maintain identical electrical and mechanical specifications including connector type, position count, pitch, contact type, termination method, fastening type, insulation material, and operating temperature range. The only difference is the housing color.

Q: What is the significance of the color difference between the three variants?

A: The color variants (Blue, Black, Gray) serve application-specific identification purposes and do not affect functional performance or compatibility. Color selection is determined by system design requirements or industry standards for circuit identification.

Q: Can I substitute a black or gray housing for a blue housing in an existing assembly?

A: Substitution is permissible from an electrical and mechanical standpoint. However, application-specific requirements such as color-coded circuit identification or visual assembly standards must be evaluated before substitution.

Q: What does the base product number 1564546 represent?

A: The base product number identifies the core connector housing design within the Heavy Duty Sealed Connector Series, MCP 6.3. The prefix digits (1, 2, or 4) designate the specific color variant while maintaining the same fundamental design and specifications.

Q: Are there any differences in RoHS compliance between the variants?

A: The main part (4-1564546-1) carries RoHS Compliant status, while the substitute parts (1-1564546-1 and 2-1564546-1) carry ROHS3 Compliant status. Both certifications indicate compliance with RoHS directives; ROHS3 represents the current revision standard.

Q: Do all variants require the same contact components?

A: Yes. All three housing variants are designed for the same tab-type crimp contacts. The note "Contacts Not Included" applies uniformly across all variants, indicating that contacts must be sourced separately and are compatible across all color options.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These connectors do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to assembly, simplifying inventory management and logistics.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All three variants are supplied in bulk packaging format, consistent with the main part specification.
