AXT420124 Equivalent & Substitute Parts Reference

Part Overview

The AXT420124 is a 20-position rectangular connector header manufactured by Panasonic Electric Works, designed for surface mount applications with center strip contacts and gold plating. This component is classified as an active product with full RoHS compliance and MSL Level 1 rating, indicating unlimited moisture exposure tolerance during storage and handling.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector position count, pitch spacing, mounting technology, contact finish, and physical stacking heights. Alternative packaging configurations may be necessary due to inventory availability or supply chain requirements while preserving functional compatibility in circuit board assembly.

Substitute Part Grouping Explanation

Substitution eligibility for the AXT420124 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 20 positions (non-negotiable)
• Pitch Spacing: 0.016" (0.40mm) center-to-center (non-negotiable)
• Row Configuration: 2 rows (non-negotiable)
• Connector Type: Header with center strip contacts (non-negotiable)
• Mounting Technology: Surface mount (non-negotiable)
• Contact Finish: Gold plating (non-negotiable)
• Physical Dimensions: Height above board 0.049" (1.25mm); mated stacking heights 1.5mm and 2.5mm (non-negotiable)
• Compliance: RoHS compliant; MSL Level 1 (non-negotiable)

The identified substitute part AXT420124A maintains all electrical and mechanical parameters identical to the main part. The only variance is packaging configuration: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Strip format. Both originate from the same manufacturer series (P4S) and share the same base product number (AXT420).

Parameter Comparison

Engineering Selection Recommendations

Both AXT420124 and AXT420124A are active products from Panasonic Electric Works with identical RoHS compliance and MSL Level 1 certification. Selection between these parts is determined by assembly process requirements and packaging handling capabilities.

The AXT420124 in Tape & Reel packaging is optimized for automated pick-and-place assembly operations, providing controlled component feeding and reduced manual handling. The AXT420124A in Strip packaging accommodates manual assembly workflows or lower-volume production runs where automated reel handling is not required.

Both parts satisfy identical electrical and mechanical interface requirements. Substitution between these variants does not affect circuit board layout, PCB footprint design, or mating connector compatibility. The choice between packaging formats is a manufacturing logistics decision rather than a functional compatibility issue.

Frequently Asked Questions (FAQ)

Q: Can AXT420124A be used as a direct replacement for AXT420124 in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. AXT420124A can be substituted if your assembly process accommodates Strip packaging instead of Tape & Reel format.

Q: Does packaging format affect the connector's performance or reliability?

A: No. Packaging format is a supply chain and assembly process variable only. Once soldered to the PCB, both parts perform identically. The connector's electrical characteristics, contact resistance, and mechanical durability are unaffected by whether it arrived in Tape & Reel or Strip packaging.

Q: Are there any PCB footprint differences between AXT420124 and AXT420124A?

A: No. Both parts share identical physical dimensions, pitch spacing (0.016" / 0.40mm), height above board (0.049" / 1.25mm), and mated stacking heights (1.5mm, 2.5mm). PCB footprint design and layout remain unchanged.

Q: What does MSL Level 1 mean for storage and handling?

A: MSL Level 1 indicates unlimited moisture sensitivity. These connectors can be stored and handled without time-based moisture exposure restrictions. Standard dry storage practices are recommended, but no special desiccant packaging or bake-out procedures are required before assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both AXT420124 and AXT420124A are RoHS compliant and meet the same regulatory requirements for restricted substance elimination.

Q: What is the significance of the P4S series designation?

A: P4S is the Panasonic Electric Works connector series identifier. Both the main part and substitute belong to this same series, confirming design compatibility and interchangeability within the product line.
