25CH-B-10 Equivalent & Substitute Parts

Part Overview

The 25CH-B-10 is a 10-position rectangular connector receptacle housing manufactured by Adam Tech, designed for applications requiring 2.50mm pitch female socket connections with crimp termination. This part operates across a temperature range of -25°C to 85°C and features friction lock fastening with polyamide (PA66) insulation material.

The 25CH-B-10 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector housing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25CH-B-10 are identified based on strict parameter matching across electrical and mechanical specifications. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (10)
• Pitch (0.098" / 2.50mm)
• Number of rows (1)
• Mounting type (Free Hanging / In-Line)
• Contact termination (Crimp)
• Fastening type (Friction Lock)
• Color (White)

Compliance Parameters:

• RoHS3 compliance
• MSL rating (1 / Unlimited)
• REACH status (Unaffected)

Substitute parts meeting all primary parameters are classified as direct equivalents. Variations in insulation material, operating temperature range, or product status do not disqualify substitution when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

25CH-C-10 (Adam Tech) is the primary substitute for the 25CH-B-10. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting method, and termination type. The 25CH-C-10 maintains active product status, ensuring ongoing availability and supply chain support. Both parts are ROHS3 compliant with MSL rating 1 and REACH unaffected status. The 25CH-C-10 is available in bulk packaging with 2952 units in stock.

0511021000 (Molex) is a parametric equivalent meeting all primary electrical and mechanical matching criteria. This part is classified as obsolete but provides cross-manufacturer compatibility for applications where Adam Tech supply is constrained. The Molex part features an extended operating temperature range (-40°C to 105°C) compared to the 25CH-B-10 (-25°C to 85°C) and uses polybutylene terephthalate (PBTP) insulation material instead of polyamide. Both materials are suitable for the specified connector application. The 0511021000 is ROHS3 compliant with MSL rating 1 and REACH unaffected status, with 1460 units in stock.

For new designs or ongoing production, the 25CH-C-10 is recommended due to active product status. For legacy system support or supply chain alternatives, the 0511021000 provides equivalent functionality with extended thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the 25CH-C-10 be used as a direct replacement for the 25CH-B-10?

A: Yes. The 25CH-C-10 meets all electrical and mechanical parameters of the 25CH-B-10, including connector type, contact configuration, pitch, mounting method, fastening type, and termination method. Both parts are ROHS3 compliant with identical MSL ratings and REACH status. The primary difference is product status: 25CH-C-10 is active while 25CH-B-10 is obsolete.

Q: What are the key differences between the Adam Tech 25CH-B-10 and the Molex 0511021000?

A: Both parts share identical electrical and mechanical specifications for connector type, positions, pitch, mounting, and termination. Differences include: insulation material (polyamide vs. polybutylene terephthalate), operating temperature range (-25°C to 85°C vs. -40°C to 105°C), and manufacturer series designation (25CH vs. Mini-Lock 51102). Both are ROHS3 compliant with MSL 1 rating.

Q: Are there packaging considerations when selecting a substitute?

A: The 25CH-B-10 packaging specification is not provided. The 25CH-C-10 is available in bulk packaging with 2952 units in stock. The 0511021000 is available in bulk packaging with 1460 units in stock. Packaging requirements should be confirmed against application specifications and procurement procedures.

Q: Do all substitute parts support crimp termination?

A: Yes. The 25CH-B-10, 25CH-C-10, and 0511021000 all specify crimp contact termination. Contacts are not included with any of these housing parts and must be sourced separately according to the connector series specifications.

Q: Are there thermal performance differences between substitutes?

A: The 25CH-B-10 and 25CH-C-10 operate across -25°C to 85°C. The Molex 0511021000 operates across -40°C to 105°C, providing extended thermal range. For applications operating within the -25°C to 85°C window, all three parts are thermally equivalent. For applications requiring extended temperature performance, the 0511021000 provides additional margin.
