M12 A-CODE 8PIN FEMALE STRAIGHT Connector 21033112801

Part Overview

The HARTING 21033112801 is an 8-position circular connector receptacle with female sockets, designed for panel mount through-hole applications with screw termination. This component features M12-8 shell size, shielded construction, and IP67 ingress protection rating. The part is classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 21033112801 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 8
• Shell Size - Insert: M12-8
• Orientation: A
• Current Rating: 2A minimum
• Voltage Rating: 30V minimum
• Operating Temperature Range: -40°C ~ 85°C
• Contact Finish - Mating: Gold

Acceptable Variation Parameters:

• Termination: Screw or Solder (both support panel mount through-hole applications)
• Mounting Feature: Bulkhead - Front Side Nut (standard for M12 panel mount)
• Shielding: Shielded or Unshielded (depends on application requirements)
• Ingress Protection: IP67 or higher (IP68 exceeds IP67 requirements)

The identified substitutes maintain all mandatory compatibility parameters while offering active product status and modern manufacturing compliance.

Parameter Comparison

Engineering Selection Recommendations

HARTING 21033212818 (har-flex® Series Insert)

This substitute is an insert-only component requiring a separate shell assembly. It maintains shielded construction and all electrical parameters of the original part. Product status is active with ROHS3 compliance. Selection of this substitute requires verification that the application design accommodates insert-only configuration and shell procurement.

TE Connectivity 5-2271143-2 (M12 Series Receptacle)

This substitute provides a complete receptacle assembly with panel mount capability, eliminating the need for separate shell components. It exceeds voltage rating specifications (60VAC/DC versus 30V) and ingress protection (IP68 versus IP67). The unshielded construction differs from the original shielded design and must be evaluated against application electromagnetic compatibility requirements. Product status is active with RoHS compliance and REACH affected designation.

Frequently Asked Questions (FAQ)

Q: Can the 21033212818 insert substitute directly replace the 21033112801 receptacle?

A: The 21033212818 is an insert-only component and does not include the shell assembly. Direct replacement requires procurement of a compatible M12-8 shell. The insert maintains electrical compatibility (8 positions, A-code orientation, 2A/30V ratings, gold contacts, shielded construction).

Q: What is the primary difference between the two substitute options?

A: The 21033212818 is an insert requiring separate shell procurement, while the 5-2271143-2 is a complete receptacle assembly. The 21033212818 maintains shielded construction identical to the original part. The 5-2271143-2 is unshielded and provides higher voltage rating (60VAC/DC).

Q: Is the 5-2271143-2 unshielded construction compatible with the original application?

A: Unshielded construction is compatible only if the original application does not require electromagnetic shielding. Review application schematics and EMC requirements to determine if shielding is necessary.

Q: What termination differences exist between substitutes?

A: The original 21033112801 uses screw termination for cable connections. Both substitutes use solder termination, requiring PCB or backshell solder connection. Termination method selection depends on assembly process and application requirements.

Q: Are both substitutes panel mount compatible?

A: The 5-2271143-2 is panel mount through-hole with bulkhead front-side nut, matching the original configuration. The 21033212818 is through-hole only without panel mount features and requires shell procurement that may include panel mount capability.

Q: Do the substitutes meet current compliance standards?

A: The 21033212818 is ROHS3 compliant. The 5-2271143-2 is RoHS compliant with REACH affected status. Both are active products suitable for new designs and obsolescence mitigation.
