Substitute Part Grouping Explanation

Substitution eligibility for the Harwin M701-250442 is determined by strict alignment with the following core parameters:

Connector Type: USB-A (USB TYPE-A)
Specifications: USB 2.0
Number of Contacts: 4
Gender: Receptacle
Mounting Type: Through Hole, Right Angle
Mounting Feature: Vertical, Flag
Termination: Solder
Features: Board Lock
Operating Temperature Range: -55°C ~ 85°C
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant or equivalent
Moisture Sensitivity Level: 1 (Unlimited)

Both identified substitute parts meet these core substitution criteria. Variations in current rating, shielding configuration, contact finish options, and mating cycle specifications do not preclude substitution when the primary functional and mechanical parameters align.

Engineering Selection Recommendations

Both CNC Tech 1002-014-01000 and Amphenol ICC 73725-0110BLF are active, in-stock alternatives to the obsolete Harwin M701-250442. Selection between these substitutes should be based on the following factors:

CNC Tech 1002-014-01000 provides the closest electrical match with a 1.5A current rating, maintaining compatibility with applications designed for the original 1A specification. This part carries ROHS3 compliance and unlimited moisture sensitivity rating, matching the original part's environmental certifications.

Amphenol ICC 73725-0110BLF offers enhanced current handling capability at 2.5A and includes shielded construction with GXT™ contact finish. This part is rated for 1500 mating cycles and carries RoHS compliance. The shielded design provides additional electromagnetic interference protection not present in the original part.

Both parts maintain identical mechanical compatibility, operating temperature range, flammability rating, and moisture sensitivity classification. Selection should prioritize application current requirements and electromagnetic environment considerations.

Frequently Asked Questions (FAQ)

Q: Can the CNC Tech 1002-014-01000 directly replace the Harwin M701-250442 in existing designs?

A: Yes. The CNC Tech part maintains identical connector type, USB 2.0 specification, contact count, mounting configuration, and board lock feature. The increased current rating of 1.5A versus 1A provides additional margin for applications originally designed for the Harwin part.

Q: What is the primary difference between the two substitute parts?

A: The Amphenol ICC 73725-0110BLF includes shielded construction and higher current rating (2.5A) compared to the unshielded CNC Tech 1002-014-01000 (1.5A). Both maintain identical mechanical and thermal specifications.

Q: Are both substitute parts RoHS compliant?

A: Yes. The CNC Tech 1002-014-01000 carries ROHS3 compliance, and the Amphenol ICC 73725-0110BLF carries RoHS compliance. Both meet regulatory requirements for restricted substance elimination.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. The CNC Tech part is supplied in Tray packaging, while the Amphenol ICC part is supplied in Tube packaging. Packaging format does not affect connector performance or board-level compatibility.

Q: Which substitute part should be selected for high-noise electromagnetic environments?

A: The Amphenol ICC 73725-0110BLF is the appropriate selection for applications requiring electromagnetic shielding. The shielded design provides noise rejection not available in the unshielded CNC Tech alternative.

Q: Are the operating temperature ranges identical across all three parts?

A: Yes. The Harwin M701-250442, CNC Tech 1002-014-01000, and Amphenol ICC 73725-0110BLF all operate across the -55°C to 85°C temperature range.
