AXE240124D Equivalent & Substitute Parts

Part Overview

The AXE240124D is a 40-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, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production runs and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AXE240124D is determined by strict parametric matching across the following critical dimensions:

• Connector Configuration: 40 positions, 2 rows, 0.016" (0.40mm) pitch
• Mounting Technology: Surface mount with solder retention capability
• Physical Envelope: 0.8mm mated stacking height, 0.026" (0.65mm) height above board
• Electrical Properties: Gold contact finish for signal integrity
• Compliance: RoHS compliance and MSL 1 rating

Three parametric equivalents meet these criteria: AXE240124 (Panasonic Electric Works, A4US series, active status), AXE640124 (Panasonic Electric Works, A4S series, active status), and BM20B(0.8)-40DP-0.4V(53) (Hirose Electric Co Ltd, BM20 series, active status). All three maintain identical electrical and mechanical specifications while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full parametric equivalence to the AXE240124D across electrical, mechanical, and environmental specifications. Selection should prioritize active product status and supply continuity:

AXE240124 (Panasonic Electric Works, A4US series) provides direct series continuity with the obsolete AXE240124D, maintaining identical series designation while offering active product status and tape & reel packaging for automated assembly processes.

AXE640124 (Panasonic Electric Works, A4S series) represents the current generation within the Panasonic rectangular connector portfolio, offering the highest inventory availability (5020 units) and active long-term support status. The A4S series supersedes the A4US series while maintaining full parametric compatibility.

BM20B(0.8)-40DP-0.4V(53) (Hirose Electric Co Ltd, BM20 series) provides cross-manufacturer equivalence with active status and established supply chain presence. This option is suitable for applications requiring multi-source qualification or where Hirose connector ecosystem integration is preferred.

All three options carry RoHS compliance certification and MSL 1 rating, ensuring compatibility with modern manufacturing processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AXE240124D be directly replaced with AXE240124?

A: Yes. AXE240124 is a parametric equivalent within the same A4US series, maintaining identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and packaging format (tape & reel versus bulk).

Q: What is the difference between AXE240124 and AXE640124?

A: Both parts are manufactured by Panasonic Electric Works and maintain identical connector specifications (40 positions, 0.40mm pitch, surface mount, gold contacts, 0.8mm stacking height). The primary differences are series designation (A4US versus A4S) and inventory availability. AXE640124 represents the current-generation A4S series and offers significantly higher stock levels.

Q: Is the Hirose BM20B(0.8)-40DP-0.4V(53) fully compatible with the AXE240124D?

A: Yes. The Hirose part meets all parametric requirements: 40 positions, 0.40mm pitch, surface mount technology, gold plating, 0.8mm stacking height, solder retention, RoHS compliance, and MSL 1 rating. Cross-manufacturer substitution is valid for applications where connector ecosystem flexibility is acceptable.

Q: Why is packaging format (bulk versus tape & reel) relevant for substitution?

A: Packaging format affects assembly process compatibility. Bulk packaging (AXE240124D) requires manual handling, while tape & reel packaging (AXE240124, AXE640124, BM20B) integrates with automated pick-and-place assembly equipment. For new production, tape & reel packaging is standard; for legacy or low-volume applications, bulk packaging may be acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. AXE240124, AXE640124, and BM20B(0.8)-40DP-0.4V(53) all carry RoHS compliance certification, meeting environmental and regulatory requirements for modern electronics manufacturing.

Q: What does MSL 1 rating mean for these connectors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. These connectors can be stored at standard ambient conditions without desiccant packaging or controlled humidity environments, simplifying inventory management and reducing storage costs.
