Adam Tech 25CH-E-03 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Adam Tech 25CH-E-03 is a 3-position rectangular connector housing designed for receptacle applications with a 2.50mm pitch. This component features crimp contact termination and friction lock fastening, suitable for free-hanging in-line mounting configurations. The housing is constructed from polyamide (PA66) nylon material and operates across a temperature range of -40°C to 105°C.

The 25CH-E-03 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this connector housing specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25CH-E-03 are determined by equivalence in the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (3)
• Pitch specification (0.098" / 2.50mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Friction Lock)
• Insulation material (Polyamide PA66 Nylon 6/6)

The identified substitute parts maintain these core electrical and mechanical parameters. Variations in color and operating temperature range do not affect functional interchangeability within the specified connector housing category.

Engineering Selection Recommendations

Both 25CH-C-03 and 25CH-E6-03 are active product alternatives to the obsolete 25CH-E-03. Selection between these substitutes should be based on application requirements:

25CH-C-03 (White): This part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range is -25°C to 85°C, which is narrower than the original part. This substitute is suitable for applications within this thermal envelope.

25CH-E6-03 (Beige): This part also maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range matches 25CH-C-03 at -25°C to 85°C. This substitute is suitable for applications within this thermal envelope.

Both substitutes share identical electrical and mechanical specifications with the main part. The primary differentiators are color designation and operating temperature range. Applications requiring the extended -40°C lower temperature limit of the original 25CH-E-03 should evaluate thermal requirements against the -25°C minimum of available substitutes.

Frequently Asked Questions (FAQ)

Q: Can 25CH-C-03 and 25CH-E6-03 be used interchangeably with 25CH-E-03?

A: Yes, both parts are functionally equivalent. They share identical connector type, contact configuration, pitch, mounting method, termination type, and insulation material. Substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between the three parts?

A: The primary differences are product status, color, and operating temperature range. The 25CH-E-03 is obsolete with natural color and -40°C to 105°C operating range. The 25CH-C-03 (white) and 25CH-E6-03 (beige) are active products with -25°C to 85°C operating ranges.

Q: Does color affect connector performance?

A: Color is a cosmetic designation and does not affect electrical or mechanical performance. Selection between natural, white, or beige variants depends on application aesthetics or identification requirements.

Q: Are there temperature limitations when substituting?

A: The substitute parts operate at -25°C to 85°C, which is narrower than the original -40°C to 105°C range. Applications requiring operation below -25°C or above 85°C cannot use these substitutes.

Q: Are all three parts RoHS and REACH compliant?

A: Yes, all three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging is available?

A: The 25CH-E-03 is available in standard packaging. The 25CH-C-03 and 25CH-E6-03 are available in bulk packaging.
