A4B-10S-2C Equivalent & Substitute Parts

Part Overview

The A4B-10S-2C is a 10-position rectangular connector housing manufactured by Hirose Electric Co Ltd. This receptacle housing is designed for crimp contact termination with a 2.00mm pitch and operates across a temperature range of -55°C to 85°C. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same connector category, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-179228-0 (TE Connectivity AMP Connectors) is classified as a parametric equivalent based on the following critical parameters that determine substitution eligibility:

• Connector Type & Contact Configuration: Both parts are receptacle housings with female socket contacts
• Position Count & Pitch: Both maintain 10 positions at 0.079" (2.00mm) pitch
• Row Configuration: Both are single-row designs
• Mounting & Termination: Both use free hanging in-line mounting with crimp contact termination
• Compliance & Environmental Rating: Both are RoHS compliant with MSL 1 (unlimited moisture sensitivity)

Variations between the main part and substitute include insulation material (PBT versus PA66 Nylon 6/6) and operating temperature range (-55°C to 85°C versus -30°C to 105°C). These differences do not preclude substitution when the application requirements fall within the overlapping operational envelope (-30°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

Both A4B-10S-2C and 1-179228-0 are active production parts with RoHS compliance and equivalent MSL ratings. Selection between these parts should be based on application-specific operating temperature requirements. The A4B-10S-2C supports operation down to -55°C, while the 1-179228-0 supports extended high-temperature operation to 105°C. For applications operating within the overlapping range of -30°C to 85°C, either part provides equivalent functionality. Insulation material differences (PBT versus PA66) and color variations (Black versus Natural) are secondary considerations that do not affect electrical or mechanical interchangeability when pitch, position count, and contact configuration remain constant.

Frequently Asked Questions (FAQ)

Q: What makes 1-179228-0 a valid substitute for A4B-10S-2C?

A: Both parts share identical electrical and mechanical specifications: 10-position receptacle housings with female socket contacts, 2.00mm pitch, single-row configuration, free hanging in-line mounting, and crimp termination. Both are RoHS compliant with MSL 1 rating and active production status.

Q: Are there differences in operating temperature between these parts?

A: Yes. The A4B-10S-2C operates from -55°C to 85°C, while the 1-179228-0 operates from -30°C to 105°C. For applications within the overlapping range (-30°C to 85°C), both parts are functionally equivalent. Applications requiring operation below -30°C must use the A4B-10S-2C.

Q: Does the insulation material difference affect substitution?

A: The A4B-10S-2C uses PBT insulation while the 1-179228-0 uses PA66 Nylon 6/6. Both materials are suitable for the specified pitch and position configuration. Material selection should be evaluated based on application-specific chemical resistance and mechanical requirements.

Q: Can color differences impact connector compatibility?

A: Color (Black for A4B-10S-2C versus Natural for 1-179228-0) is a cosmetic attribute and does not affect electrical or mechanical compatibility. Selection based on color is a design or identification preference only.

Q: Are contacts included with these housings?

A: No. Both the A4B-10S-2C and 1-179228-0 are housings only. Contacts must be sourced separately and are not included with these parts.
