Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXE526127 is based on the following critical electrical and mechanical parameters that must remain constant:

• Number of Positions: 26 (fixed requirement)
• Pitch: 0.016" (0.40mm) (fixed requirement)
• Number of Rows: 2 (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Contact Finish: Gold (fixed requirement)
• Connector Category: Rectangular Connectors (fixed requirement)

The AXT526124 qualifies as a substitute part because it maintains all critical parameters. The primary difference lies in the connector type (outer shroud contacts versus center strip contacts) and physical height dimensions, which represent acceptable design variations within the same connector family. Both parts share identical pitch, position count, row configuration, and mounting methodology, ensuring PCB footprint compatibility and electrical interface equivalence.

Parameter Comparison

Engineering Selection Recommendations

The AXT526124 is the qualified substitute for the obsolete AXE526127 based on the following criteria:

Compliance & Availability: The AXT526124 maintains active product status with 1700 units in stock, compared to the obsolete AXE526127. Both parts meet RoHS requirements, with AXT526124 achieving ROHS3 compliance, representing current regulatory standards.

Electrical Equivalence: Both connectors maintain identical electrical specifications: 26 positions, 0.016" (0.40mm) pitch, 2-row configuration, gold contact finish, and solder retention features. These parameters ensure direct electrical interface compatibility with mating connectors and PCB traces.

Mechanical Considerations: The AXT526124 exhibits a slightly increased height above board (0.038" versus 0.030") and standardized mated stacking height of 1mm. These dimensional differences must be evaluated within the context of available board clearance and assembly constraints in the target application.

Contact Architecture Difference: The transition from center strip contacts (AXE526127) to outer shroud contacts (AXT526124) represents a design evolution within the Panasonic rectangular connector family. Both architectures provide equivalent contact retention and signal integrity for the specified pitch and position count.

Frequently Asked Questions (FAQ)

Q: Can AXT526124 be used as a direct replacement for AXE526127 on existing PCBs?

A: The AXT526124 shares identical pitch (0.016"), position count (26), row configuration (2), and mounting type (surface mount) with the AXE526127. PCB footprints designed for the AXE526127 will accommodate the AXT526124. However, the increased height above board (0.038" versus 0.030") must be verified against available clearance in the assembly. Mating connector compatibility should be confirmed with the connector manufacturer.

Q: What is the difference between center strip contacts and outer shroud contacts?

A: Center strip contacts (AXE526127) position the contact elements along a central conductor strip, while outer shroud contacts (AXT526124) integrate contacts within an outer shroud structure. Both architectures maintain equivalent electrical performance for the specified pitch and position configuration. The outer shroud design may provide enhanced mechanical stability and contact retention.

Q: Are both parts RoHS compliant?

A: Yes. The AXE526127 is RoHS Compliant, and the AXT526124 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. ROHS3 represents the current regulatory standard and indicates the AXT526124 meets the latest compliance requirements.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or transport. This classification allows standard warehouse conditions without specialized desiccant packaging or environmental controls.

Q: Is the AXT526124 available in the same packaging as the AXE526127?

A: The AXT526124 is supplied in Tape & Reel (TR) packaging with 1700 units in stock. The AXE526127 packaging specification was not provided in the technical data. Tape & Reel packaging is standard for surface mount connectors and is compatible with automated assembly equipment.

Q: What is the base product number, and how does it relate to these parts?

A: The AXE526127 belongs to the AXE526 base product family (A4S series), while the AXT526124 belongs to the AXT526 base product family (F4S series). These designations indicate different connector series within the Panasonic rectangular connector portfolio, each with distinct contact architectures and mechanical features.
