AXT770124 Equivalent & Substitute Parts

Part Overview

The AXT770124 is a 70-position rectangular connector socket manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing production and maintenance applications. The connector features solder retention and operates with a 0.35mm pitch across 2 rows, making it suitable for high-density interconnect requirements.

Key Parameters

Substitute Part Grouping Explanation

The AXT170114 qualifies as a functional equivalent to the AXT770124 based on the following critical parameters that determine substitutability:

• Connector Type: Both are socket connectors with center strip contacts
• Number of Positions: Both feature 70 positions
• Pitch: Both maintain 0.014" (0.35mm) pitch spacing
• Number of Rows: Both are configured as 2-row connectors
• Mounting Type: Both are surface mount designs
• Contact Finish: Both utilize gold plating
• Features: Both include solder retention capability
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)

The primary distinction is that AXT170114 is an active product from the P35S series with improved availability, whereas AXT770124 is obsolete from the F35S series. Physical dimensions differ slightly (mated stacking height and height above board), which must be evaluated within specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

The AXT170114 is the designated substitute for the obsolete AXT770124. Selection of AXT170114 is supported by:

• Active Product Status: AXT170114 maintains active manufacturing status with confirmed inventory availability (1079 pcs), ensuring supply chain continuity
• Compliance Certification: AXT170114 is RoHS Compliant, meeting current regulatory requirements for electronic components
• Electrical Compatibility: Identical electrical specifications across all critical parameters (positions, pitch, rows, contact finish, and features) ensure functional interchangeability
• Physical Accommodation: The increased mated stacking height (1.5mm vs. 1mm) and height above board (0.057" vs. 0.038") must be evaluated against PCB layout constraints and mating component clearances

Design validation should confirm that the dimensional differences do not conflict with existing mechanical constraints or mating interface requirements.

Frequently Asked Questions (FAQ)

Q: Can AXT170114 be used as a direct replacement for AXT770124?

A: AXT170114 is electrically and functionally equivalent to AXT770124 across all critical connector specifications. However, the increased physical dimensions (mated stacking height and height above board) require verification that PCB layout and mating component clearances accommodate these differences.

Q: What is the primary reason for substitution?

A: AXT770124 is classified as obsolete. AXT170114 is an active product from Panasonic Electric Works that maintains identical electrical and functional characteristics, ensuring continued availability for production and maintenance applications.

Q: Are there packaging differences between these parts?

A: AXT770124 packaging information is not specified in available data. AXT170114 is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production environments.

Q: Does AXT170114 meet current compliance standards?

A: Yes, AXT170114 is RoHS Compliant. Both parts are classified as EAR99 for export control purposes and share identical HTSUS classification (8536.69.4040).

Q: What are the key dimensional differences?

A: Mated stacking height increases from 1mm to 1.5mm, and height above board increases from 0.038" (0.97mm) to 0.057" (1.45mm). These differences must be evaluated within specific application PCB and enclosure constraints.

Q: Are the moisture sensitivity levels equivalent?

A: Yes, both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
