Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 440247-3 are qualified based on strict equivalence across the following core parameters:

• Connector Type: USB - mini B (5-position receptacle)
• Mounting Configuration: Surface mount, right-angle, horizontal orientation
• Termination Method: Solder attachment
• Functional Features: Board guide and solder retention
• Material Compliance: UL94 V-0 flammability rating
• Contact Material: Gold finish
• Moisture Sensitivity: MSL 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in operating temperature range, current rating, mating cycles, shielding configuration, and shell material are documented but do not disqualify substitution where the primary functional requirements are met.

Engineering Selection Recommendations

Direct Replacement - TE Connectivity 1734035-3

The TE Connectivity 1734035-3 is the primary direct substitute for the obsolete 440247-3. Both parts are manufactured by TE Connectivity AMP Connectors and share identical connector type, contact count, mounting configuration, and termination method. The 1734035-3 carries active product status and is ROHS3 compliant, addressing regulatory requirements that the original part does not meet. This part is available in Tape & Reel packaging with 34,046 units in stock. The 1734035-3 provides specified operating temperature range (-40°C ~ 85°C), current rating (1A), voltage rating (30VAC), and mating cycle specification (5000 cycles), offering enhanced reliability documentation compared to the original part.

Alternative Substitute - Harwin Inc. M701-340542

The Harwin M701-340542 provides functional equivalence across all core parameters with extended operating temperature range (-55°C ~ 105°C). This part is ROHS3 compliant and available in bulk packaging with 1,081 units in stock. The M701-340542 features an unshielded configuration with brass shell material, differing from the original phosphor bronze specification. This alternative is suitable for applications where extended temperature performance is required and shielding is not a design constraint.

Parametric Equivalent - Samtec Inc. MUSB-05-S-B-SM-A-R-TR

The Samtec MUSB-05-S-B-SM-A-R-TR meets all core functional parameters with ROHS3 compliance and active product status. This part is supplied in Tape & Reel packaging with 725 units in stock. The MUSB-05-S-B-SM-A-R-TR operates across -50°C ~ 85°C temperature range with 1500 mating cycles and 30V voltage rating. The unshielded configuration with copper alloy shell material differs from the original specification. This option is appropriate for applications where Samtec connector ecosystem integration is preferred.

Compliance Consideration

All three substitute parts are ROHS3 compliant, addressing regulatory requirements not met by the obsolete 440247-3. Selection should prioritize the TE Connectivity 1734035-3 for direct manufacturer continuity and highest inventory availability (34,046 units). Alternative selections should be based on specific application requirements regarding temperature range, shielding configuration, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1734035-3 be used as a direct replacement for the 440247-3?

A: Yes. Both parts share identical connector type (USB mini B), contact count (5), gender (receptacle), mounting configuration (surface mount, right angle, horizontal), termination method (solder), and core features (board guide, solder retention). The 1734035-3 is the active product equivalent with enhanced specifications and ROHS3 compliance.

Q: What is the primary difference between the 1734035-3 and the M701-340542?

A: The 1734035-3 features a shielded configuration with steel shell material and operates across -40°C ~ 85°C. The M701-340542 is unshielded with brass shell material and operates across -55°C ~ 105°C. Both maintain identical connector type, contact count, and mounting configuration. Selection depends on shielding requirements and operating temperature specifications.

Q: Does the Samtec MUSB-05-S-B-SM-A-R-TR provide equivalent functionality?

A: Yes. The MUSB-05-S-B-SM-A-R-TR maintains all core functional parameters: USB mini B receptacle, 5 contacts, surface mount right-angle configuration, solder termination, and board guide/solder retention features. The unshielded design and copper alloy shell differ from the original specification but do not affect core USB 2.0 functionality.

Q: What packaging options are available for these substitutes?

A: The TE Connectivity 1734035-3 and Samtec MUSB-05-S-B-SM-A-R-TR are supplied in Tape & Reel (TR) packaging. The Harwin M701-340542 is supplied in bulk packaging. Packaging selection should align with manufacturing process requirements and volume specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (1734035-3, M701-340542, and MUSB-05-S-B-SM-A-R-TR) are ROHS3 compliant. The original 440247-3 is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulatory requirements.

Q: What are the mating cycle specifications for each substitute?

A: The TE Connectivity 1734035-3 specifies 5000 mating cycles. The Samtec MUSB-05-S-B-SM-A-R-TR specifies 1500 mating cycles. The Harwin M701-340542 does not provide a mating cycle specification. Selection should consider application duty cycle requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, provided the PCB footprint accommodates the specific connector dimensions. All substitute parts maintain identical mounting type (surface mount, right angle, horizontal) and 5-position contact configuration. Physical dimensions should be verified against PCB design specifications before implementation.

Q: What is the current rating for each substitute part?

A: The TE Connectivity 1734035-3 and Harwin M701-340542 both specify 1A current rating. The Samtec MUSB-05-S-B-SM-A-R-TR does not provide a current rating specification. Applications requiring specified current capacity should prioritize the 1734035-3 or M701-340542.
