AXE220124D Equivalent & Substitute Parts

Part Overview

The AXE220124D is a 20-position rectangular connector header manufactured by Panasonic Electric Works, designed for surface mount applications with outer shroud contacts and gold plating. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part belongs to the A4US series and maintains full RoHS compliance with MSL Level 1 rating.

Substitute Part Grouping Explanation

Substitution for the AXE220124D is determined by strict equivalence across the following critical parameters: connector type (header with outer shroud contacts), position count (20), pitch specification (0.40mm), row configuration (2 rows), mounting method (surface mount), contact material (gold), and physical dimensions (0.8mm stacking height, 0.65mm height above board). All substitute parts maintain identical electrical and mechanical specifications, RoHS compliance, and MSL Level 1 rating.

The substitutes are grouped into two categories:

Panasonic Electric Works Series Variants: AXE220124 (Active, Tape & Reel packaging) and AXE620124 (Active, Cut Tape & Digi-Reel packaging) represent direct parametric equivalents from the same manufacturer with identical connector specifications but different series designations and packaging formats.

Cross-Manufacturer Equivalent: BM20B(0.8)-20DP-0.4V(53) from Hirose Electric Co Ltd provides parametric equivalence across all critical dimensions and electrical characteristics, representing an alternative source for the same connector function.

Engineering Selection Recommendations

All three substitute parts are active products with full RoHS compliance and MSL Level 1 certification, making them suitable replacements for the obsolete AXE220124D in new designs and production continuity scenarios.

AXE220124 maintains identical series designation (A4US) and represents the direct active equivalent with Tape & Reel packaging. This part is recommended for applications requiring continuity within the Panasonic A4US series family.

AXE620124 provides parametric equivalence within the Panasonic product line but operates under the A4S series designation with Cut Tape & Digi-Reel packaging. This part offers the highest inventory availability (111,468 pieces) and represents an alternative within the Panasonic rectangular connector portfolio.

BM20B(0.8)-20DP-0.4V(53) from Hirose Electric Co Ltd delivers complete parametric equivalence from an alternative manufacturer. This option is applicable for applications where multi-source qualification is required or where Hirose connector ecosystem integration is preferred.

Frequently Asked Questions (FAQ)

Q: Can AXE220124 directly replace AXE220124D in existing designs?

A: Yes. AXE220124 maintains identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, contact finish, and physical dimensions. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel versus unspecified).

Q: What is the difference between AXE220124 and AXE620124?

A: Both parts are parametrically equivalent 20-position surface mount headers with 0.40mm pitch and gold contacts. The primary differences are series designation (A4US versus A4S), base product number (AXE220 versus AXE620), packaging format (Tape & Reel versus Cut Tape & Digi-Reel), and inventory availability. All electrical and mechanical parameters remain identical.

Q: Is the Hirose BM20B(0.8)-20DP-0.4V(53) a true equivalent?

A: Yes. The Hirose part matches all critical parameters: 20 positions, 0.40mm pitch, 2-row configuration, surface mount mounting, gold contact finish, 0.8mm stacking height, and 0.65mm height above board. It is a cross-manufacturer equivalent suitable for applications requiring alternative sourcing.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. AXE220124 is supplied in Tape & Reel format, while AXE620124 uses Cut Tape & Digi-Reel packaging. BM20B(0.8)-20DP-0.4V(53) is supplied in Tape & Reel format. Packaging selection should align with assembly line requirements and component handling procedures.

Q: Do all substitutes maintain RoHS compliance?

A: Yes. All three substitute parts are RoHS Compliant with MSL Level 1 (Unlimited) rating, matching the compliance profile of the original AXE220124D.

Q: Which substitute offers the best inventory availability?

A: AXE620124 provides the highest inventory level at 111,468 pieces in stock, followed by AXE220124 at 780 pieces and BM20B(0.8)-20DP-0.4V(53) at 1,669 pieces.
