A4B-5S-2C Equivalent & Substitute Parts

Part Overview

The A4B-5S-2C is a 5-position rectangular connector housing manufactured by Hirose Electric Co Ltd. This receptacle connector operates at a 2.00mm pitch and is designed for free-hanging in-line mounting with crimp contact termination. The part is currently active in production with 895 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A4B-5S-2C is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 5
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts 440129-5 and 69305-005LF meet all mandatory electrical and mechanical parameters. Variations in insulation material, color, operating temperature range, and manufacturer series do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three parts—A4B-5S-2C, 440129-5, and 69305-005LF—are active products with RoHS compliance and MSL 1 rating. Selection between these parts should be based on:

• Availability: 440129-5 has the highest inventory (137,217 units), followed by A4B-5S-2C (895 units) and 69305-005LF (1,314 units).
• Operating Temperature Requirements: If the application requires operation below -25°C, the A4B-5S-2C (-55°C minimum) is the appropriate choice. For applications within -25°C to 105°C, 440129-5 and 69305-005LF are suitable.
• Regulatory Status: 69305-005LF is REACH Affected; A4B-5S-2C is REACH Unaffected; 440129-5 is Vendor Undefined for REACH status.
• Material Compatibility: Insulation material differences (PBT, Thermoplastic, PA66) may influence selection based on chemical exposure or mechanical stress requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 440129-5 be used as a direct replacement for A4B-5S-2C?

A: Yes. Both parts share identical connector type, contact type, position count, pitch, row configuration, mounting type, contact termination, and MSL rating. The operating temperature range of 440129-5 (-25°C ~ 105°C) is wider than A4B-5S-2C (-55°C ~ 85°C) at the upper end but narrower at the lower end. Verify application temperature requirements before substitution.

Q: What are the key differences between A4B-5S-2C and 69305-005LF?

A: Both parts are functionally equivalent based on electrical and mechanical parameters. The primary differences are insulation material (PBT versus PA66 glass-filled nylon), operating temperature range (-55°C ~ 85°C versus -40°C ~ 105°C), and REACH compliance status (Unaffected versus Affected). Color is also different (Black for both, but from different material compositions).

Q: Are contacts included with these connector housings?

A: No. All three parts are connector housings only. Contacts must be procured separately and are not included in the package.

Q: What is the significance of the pitch specification?

A: Pitch (0.079" or 2.00mm) defines the center-to-center distance between adjacent contact positions. All three parts share this specification, ensuring mechanical and electrical compatibility within the 5-position configuration.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability is confirmed for the connector housing function. However, verify that mating connectors, PCB footprints, and assembly processes are compatible with the selected substitute part, particularly regarding insulation material and color variations.
