CNC Tech 54025-16 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The CNC Tech 54025-16 is a 16-position rectangular connector housing designed for receptacle applications with a 2.50mm pitch. This component functions as the insulating body that holds female socket contacts in a free-hanging, in-line configuration. The part is actively manufactured and maintained in production status. Substitute parts may be required due to inventory availability, color specification requirements, or thermal operating range constraints specific to application demands.

Key Parameters

Substitute Part Grouping Explanation

The CNC Tech 53025-16 is classified as a parametric equivalent to the 54025-16 based on the following matching electrical and mechanical parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Position count: 16
• Pitch specification: 0.098" (2.50mm)
• Row configuration: 2 rows at 0.098" (2.50mm) spacing
• Mounting method: Free hanging (in-line)
• Termination method: Crimp
• Fastening mechanism: Latch lock
• Compliance certifications: ROHS3 compliant, REACH unaffected
• Moisture sensitivity: MSL 1 (unlimited)

Differences between these parts are limited to color specification (black versus white) and insulation material composition, which do not affect electrical or mechanical interchangeability within the defined connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both the 54025-16 and 53025-16 maintain active production status and satisfy ROHS3 compliance and REACH regulatory requirements. Selection between these parts depends on application-specific constraints:

The 54025-16 (black, PA4T insulation) operates across a wider temperature range of -40°C to 105°C and is suitable for applications requiring extended thermal performance.

The 53025-16 (white, PA66 insulation) operates within -25°C to 85°C and is suitable for standard industrial temperature environments. The white color specification may be required for visual identification or assembly traceability purposes.

Both parts are electrically and mechanically interchangeable within their respective operating temperature ranges. Selection should be based on thermal requirements, color specification needs, and material composition compatibility with the application environment.

Frequently Asked Questions (FAQ)

Q: Are the 54025-16 and 53025-16 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including connector type (receptacle), contact type (female socket), position count (16), pitch (2.50mm), row configuration, termination method (crimp), and fastening mechanism (latch lock).

Q: What is the primary difference between these two connector housings?

A: The primary differences are color (black versus white), insulation material composition (PA4T nylon 4T versus PA66 nylon 6/6), and operating temperature range (54025-16: -40°C to 105°C; 53025-16: -25°C to 85°C).

Q: Can I use the 53025-16 in an application requiring -40°C operation?

A: No. The 53025-16 has a minimum operating temperature of -25°C. For applications requiring -40°C operation, the 54025-16 must be used.

Q: Do these connector housings include contacts?

A: No. Both the 54025-16 and 53025-16 are housings only. Female socket contacts must be sourced separately and installed via crimp termination.

Q: Are both parts RoHS compliant?

A: Yes. Both the 54025-16 and 53025-16 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry an MSL rating of 1 (unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can color be used as a substitution criterion?

A: Color is a visual specification only and does not affect electrical or mechanical function. Substitution based on color depends on application requirements for identification or traceability purposes.
