Key Parameters

Substitute Part Grouping Explanation

Substitution of the 25CH-B-09 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle housing
• Contact type: Female socket
• Number of positions: 9
• Pitch specification: 0.098" (2.50mm)
• Number of rows: 1
• Mounting configuration: Free hanging (in-line)
• Contact termination method: Crimp
• Fastening mechanism: Friction lock
• Insulation material: Polyamide (PA66), Nylon 6/6
• Operating temperature range: -25°C to 85°C
• Color: White

The 25CH-C-09 meets all these parameters and is classified as an active product, making it a direct functional equivalent for the obsolete 25CH-B-09.

Parameter Comparison

Engineering Selection Recommendations

The 25CH-C-09 is the direct substitute for the obsolete 25CH-B-09. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 25CH-C-09 carries active product status with current inventory availability, ensuring supply chain continuity. Both parts maintain equivalent regulatory compliance, including ROHS3 certification and REACH unaffected status. The transition from 25CH-B-09 to 25CH-C-09 requires no design modifications or re-qualification of existing assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 25CH-C-09 be used as a direct replacement for the 25CH-B-09?

A: Yes. The 25CH-C-09 is electrically and mechanically equivalent to the 25CH-B-09 across all specified parameters, including connector type, position count, pitch, mounting configuration, and operating temperature range.

Q: What is the primary difference between these two parts?

A: The 25CH-B-09 is classified as obsolete, while the 25CH-C-09 is an active product with current manufacturing and inventory support. The base product numbers differ (25CH-B versus 25CH-C), but functional specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (unlimited).

Q: Does packaging differ between these parts?

A: The 25CH-B-09 was supplied in standard packaging, while the 25CH-C-09 is available in bulk packaging. This difference does not affect component functionality or compatibility.

Q: Are contacts included with these connector housings?

A: No. Both the 25CH-B-09 and 25CH-C-09 are housings only. Contacts must be sourced separately and are not included with either part.
