25CH-E-05 Rectangular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The 25CH-E-05 is a 5-position rectangular connector receptacle housing manufactured by Adam Tech with a 0.098" (2.50mm) pitch. This component is designed for free-hanging in-line applications using crimp termination with friction lock fastening. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25CH-E-05 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match for functional equivalence:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 5
• Pitch: 0.098" (2.50mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Friction Lock
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Series: 25CH

The substitute parts 25CH-E6-05 and 25CH-C-05 meet all these core compatibility requirements. Variations in color (Natural, White, Beige) and operating temperature ranges do not affect mechanical or electrical interchangeability for housing applications.

Parameter Comparison

Engineering Selection Recommendations

Both 25CH-E6-05 and 25CH-C-05 are active product alternatives to the obsolete 25CH-E-05. Selection between these substitutes should be based on the following factors:

25CH-E6-05 (Beige): This part maintains the extended operating temperature range of -25°C ~ 85°C and is available in high inventory (5599 pcs). It is suitable for applications where the wider temperature capability of the original part is not required.

25CH-C-05 (White): This part operates within the same temperature range as 25CH-E6-05 (-25°C ~ 85°C) and is available in substantial inventory (1462 pcs). Color differentiation may be relevant for system identification or assembly documentation purposes.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original part. The primary distinction between the main part and substitutes is the operating temperature range; applications requiring the full -40°C ~ 105°C range of the 25CH-E-05 should evaluate thermal requirements against the -25°C ~ 85°C capability of the active alternatives.

Frequently Asked Questions (FAQ)

Q: Can 25CH-E6-05 and 25CH-C-05 be used interchangeably with 25CH-E-05?

A: Yes, both parts are mechanically and electrically interchangeable with the 25CH-E-05 for housing applications. All three parts share identical connector type, contact configuration, pitch, mounting method, and termination specifications. The differences are limited to color and operating temperature range.

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

A: Color variation (Natural, Beige, White) is a cosmetic and identification feature only. It does not affect electrical or mechanical performance. Color selection may be driven by assembly documentation, system identification requirements, or inventory availability.

Q: Why does the 25CH-E-05 have a wider operating temperature range than the substitutes?

A: The 25CH-E-05 operates from -40°C ~ 105°C, while 25CH-E6-05 and 25CH-C-05 operate from -25°C ~ 85°C. This difference reflects the product specifications as provided. Applications requiring operation below -25°C or above 85°C must use the original 25CH-E-05 or identify alternative solutions outside this product family.

Q: Are there packaging differences between these parts?

A: The 25CH-E-05 is listed with no specified packaging, while 25CH-E6-05 and 25CH-C-05 are supplied in Bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.

Q: Do all three parts meet the same regulatory standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL Rating 1 (Unlimited). Regulatory compliance is equivalent across all three options.

Q: What is the inventory status of each part?

A: 25CH-E-05 (Obsolete): 723 pcs in stock; 25CH-E6-05 (Active): 5599 pcs in stock; 25CH-C-05 (Active): 1462 pcs in stock. The active alternatives offer significantly higher availability.
