AXG8120J4 Equivalent & Substitute Parts

Part Overview

The AXG8120J4 is a 14-position rectangular connector plug manufactured by Panasonic Electric Works, featuring outer shroud contacts with surface mount gold plating. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning.

The connector is designed for applications requiring reliable signal and power distribution across 12 signal positions plus 2 dedicated power positions. Due to its obsolete status, sourcing direct replacements requires evaluation of active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXG8120J4 is determined by the following critical parameters:

• Pitch (0.014" / 0.35mm): Contact spacing must match exactly to ensure mechanical and electrical compatibility with mating connectors
• Mounting Type (Surface Mount): PCB assembly process compatibility requires identical mounting methodology
• Contact Finish (Gold): Electrical performance and corrosion resistance specifications demand matching contact material
• Mated Stacking Height (0.6mm): Physical clearance and connector engagement depth must be preserved
• RoHS Compliance: Regulatory requirement for component selection in applicable markets
• Moisture Sensitivity Level (MSL 1): Storage and handling requirements must be equivalent or superior

The substitute part AXF6D1212 shares these core parameters with the main part. However, the connector type differs (Header vs. Plug) and the position count is reduced (12 vs. 14 positions). These differences require careful evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The AXF6D1212 maintains electrical and mechanical compatibility across all critical parameters: pitch, mounting type, contact finish, stacking height, and compliance certifications. The primary distinction is the connector type (Header vs. Plug configuration) and reduced position count (12 vs. 14).

Selection of AXF6D1212 as a substitute is supported by its active product status, which ensures ongoing availability and manufacturing consistency compared to the obsolete AXG8120J4. Both components meet identical RoHS and MSL requirements, eliminating regulatory or environmental concerns in the substitution.

The position count reduction from 14 to 12 requires verification that the application circuit design can accommodate the loss of 2 positions. The connector type change from Plug to Header necessitates corresponding changes to the mating connector configuration in the system design.

Frequently Asked Questions (FAQ)

Q: Can AXF6D1212 directly replace AXG8120J4 without PCB redesign?

A: Direct replacement without modification is not possible due to two factors: the connector type differs (Header vs. Plug), requiring a corresponding change to the mating connector, and the position count is reduced (12 vs. 14), which may affect circuit routing if all 14 positions are utilized.

Q: Are the electrical performance characteristics identical between these parts?

A: Both components share matching pitch (0.35mm), contact finish (Gold), and stacking height (0.6mm), which are the primary determinants of electrical performance in rectangular connector applications. These parameters ensure equivalent signal integrity and power distribution capability within the specified position count.

Q: What is the significance of the connector type difference?

A: The AXG8120J4 is a Plug configuration (male), while AXF6D1212 is a Header configuration (female). These are complementary connector types designed to mate with opposite gender connectors. System redesign must account for this polarity reversal.

Q: Does the active product status of AXF6D1212 affect long-term availability?

A: Active product status indicates current manufacturing and distribution support. This status provides greater assurance of consistent availability compared to obsolete components, which may have limited remaining inventory and no ongoing production.

Q: Are there packaging differences between these parts?

A: AXG8120J4 packaging is not specified in the provided data. AXF6D1212 is supplied in Tape & Reel (TR) format, which is standard for surface mount component automation and high-volume assembly processes.
