25CH-E-09 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The 25CH-E-09 is a 9-position rectangular connector housing manufactured by Adam Tech, designed for receptacle applications with a 2.50mm pitch. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design and procurement requirements. The housing accommodates female socket contacts with crimp termination and friction lock fastening, suitable for free-hanging in-line mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25CH-E-09 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 9 positions at 0.098" (2.50mm) pitch
• Mounting & Termination: Free hanging in-line mounting with crimp contact termination
• Fastening Mechanism: Friction lock fastening
• Material & Environmental Compliance: Polyamide (PA66) insulation, ROHS3 compliance, REACH unaffected status

The 25CH-C-09 qualifies as a substitute based on matching all critical electrical and mechanical parameters within the 25CH series. Both housings accommodate identical contact configurations, pitch spacing, and termination methods. Differences in color (natural vs. white) and operating temperature range do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The 25CH-C-09 is the designated substitute for the obsolete 25CH-E-09. Both components maintain identical electrical and mechanical specifications across all critical parameters: 9-position configuration, 2.50mm pitch, female socket contacts, crimp termination, and friction lock fastening.

The 25CH-C-09 offers the advantage of active product status with higher current inventory availability (4116 pcs vs. 1061 pcs), ensuring supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The operating temperature range of the 25CH-C-09 (-25°C ~ 85°C) is narrower than the 25CH-E-09 (-40°C ~ 105°C). Component selection should account for application-specific temperature requirements. The color difference (white vs. natural) is a cosmetic distinction without functional impact on electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 25CH-E-09 and 25CH-C-09 mechanically interchangeable?

A: Yes. Both housings share identical pitch (2.50mm), position count (9), mounting type (free hanging in-line), and contact termination method (crimp). They are mechanically interchangeable within the 25CH series.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 25CH-E-09 is classified as obsolete, indicating discontinued manufacturing. The 25CH-C-09 maintains active status with ongoing production and higher inventory levels, making it the preferred choice for new designs and replenishment.

Q: Does the color difference affect connector performance?

A: No. Color is a cosmetic attribute determined by insulation material pigmentation. Both natural and white variants use identical Polyamide (PA66) insulation and do not affect electrical or mechanical functionality.

Q: Are there temperature limitations when substituting the 25CH-C-09 for the 25CH-E-09?

A: The 25CH-C-09 operates within -25°C ~ 85°C, compared to the 25CH-E-09 range of -40°C ~ 105°C. Applications requiring operation below -25°C or above 85°C must evaluate alternative solutions or confirm the 25CH-C-09 meets specific thermal requirements.

Q: Do both parts comply with regulatory standards?

A: Yes. Both the 25CH-E-09 and 25CH-C-09 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the packaging difference between these parts?

A: The 25CH-E-09 is supplied without specified packaging notation, while the 25CH-C-09 is packaged in bulk. Packaging format does not affect component functionality or interchangeability.
