Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 440247-4 are qualified based on strict equivalence across the following parameters: connector type (USB mini B), contact count (5 positions), gender (receptacle), USB specification (2.0), mounting configuration (surface mount, right angle, horizontal), termination method (solder), and material compliance (UL94 V-0 flammability rating). All substitute parts maintain gold contact finish, black insulation, and MSL 1 rating. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions based on availability and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1734035-4 is the primary direct substitute for the obsolete 440247-4. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical mechanical and electrical interface specifications. The 1734035-4 is active product status with ROHS3 compliance, addressing the RoHS non-compliance limitation of the original part. This substitute provides specified operating temperature range (-40°C to 85°C), current rating (1A), voltage rating (30VAC), and mating cycle specification (5000 cycles). The shielded configuration with steel shell material offers enhanced electromagnetic interference protection. Packaging is available in Cut Tape format.

Harwin Inc. M701-340542 qualifies as an active substitute with ROHS3 compliance and extended operating temperature range (-55°C to 105°C). This part is unshielded with brass shell material and is available in bulk packaging. The M701-340542 supports 1A current rating and maintains all core mechanical interface parameters.

Samtec Inc. MUSB-05-S-B-SM-A-R-TR is an active parametric equivalent with ROHS3 compliance, operating temperature range (-50°C to 85°C), and 30V voltage rating. This part is unshielded with copper alloy shell material and is supplied in Tape & Reel packaging. Mating cycle specification is 1500 cycles.

All three substitute parts maintain functional equivalence for USB 2.0 mini B receptacle applications requiring surface mount, right-angle, horizontal mounting with solder termination and board guide features.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1734035-4 directly replace the obsolete 440247-4 in existing designs?

A: Yes. The 1734035-4 maintains identical connector type, contact count, gender, USB specification, mounting configuration, and termination method. Both parts feature board guide and solder retention. The primary design advantage of the 1734035-4 is active product status, ROHS3 compliance, and specified electrical performance parameters (1A current, 30VAC, 5000 mating cycles).

Q: What is the difference between shielded and unshielded configurations?

A: The TE Connectivity 1734035-4 is shielded with steel shell material, providing electromagnetic interference protection. The Harwin M701-340542 and Samtec MUSB-05-S-B-SM-A-R-TR are unshielded with brass and copper alloy shell materials respectively. Shielding selection depends on application electromagnetic environment requirements.

Q: How do operating temperature ranges differ among substitutes?

A: The TE Connectivity 1734035-4 operates from -40°C to 85°C. The Harwin M701-340542 supports extended range -55°C to 105°C. The Samtec MUSB-05-S-B-SM-A-R-TR operates from -50°C to 85°C. Selection depends on target application thermal environment specifications.

Q: What packaging options are available?

A: The TE Connectivity 1734035-4 is supplied in Cut Tape (CT) packaging. The Harwin M701-340542 is available in bulk packaging. The Samtec MUSB-05-S-B-SM-A-R-TR is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (1734035-4, M701-340542, MUSB-05-S-B-SM-A-R-TR) are ROHS3 compliant. The original 440247-4 is RoHS non-compliant, making substitution necessary for applications requiring RoHS compliance.

Q: What is the mating cycle specification difference?

A: The TE Connectivity 1734035-4 supports 5000 mating cycles. The Samtec MUSB-05-S-B-SM-A-R-TR supports 1500 mating cycles. The Harwin M701-340542 does not specify mating cycles. Selection depends on connector insertion/removal frequency requirements over product lifetime.

Q: Do all substitutes maintain the same contact finish?

A: Yes. All parts, including the original 440247-4 and all three substitutes, feature gold contact finish and black insulation color. All maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level.
