Substitute Part Grouping Explanation

Substitution of the obsolete 5748394-5 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub, High Density
• Connector type: Receptacle, Female Sockets
• Number of positions: 62
• Number of rows: 3
• Shell size and layout: 4 (DC, C) High Density
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Shell material and finish: Steel, Nickel Plated
• Contact finish: Gold
• Operating temperature range: -55°C to 105°C
• Series: AMPLIMITE HD-22
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The substitute part TE Connectivity 2311771-1 satisfies all mandatory matching parameters. Differences in current rating (3A versus 2A) and material flammability rating (UL94 V-0 versus unspecified) represent enhancements that do not preclude substitution. The active product status of 2311771-1 ensures ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2311771-1 is the direct functional equivalent for the obsolete 5748394-5. Selection of 2311771-1 is supported by the following engineering criteria:

Product Status: The substitute part maintains active product status, ensuring continued manufacturing support, documented supply chain availability, and technical documentation access. The main part's obsolete classification creates supply risk for new production and field service requirements.

Electrical and Mechanical Compatibility: All critical electrical parameters (voltage rating, contact finish, operating temperature range) and mechanical parameters (connector geometry, mounting configuration, shell size) are identical between the two parts. The substitute's higher current rating (3A versus 2A) provides enhanced performance margin without introducing incompatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage requirements. The substitute's UL94 V-0 material flammability rating represents an enhanced specification that does not restrict application scope.

Physical Interchangeability: Both connectors share identical shell size (4 DC, C), pin count (62), row configuration (3), and right-angle through-hole mounting, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 2311771-1 substitute directly replace the 5748394-5 without PCB redesign?

A: Yes. Both connectors share identical shell size (4 DC, C), mounting type (through-hole right angle), and pin configuration (62 positions, 3 rows). No PCB layout modifications are required.

Q: What is the significance of the higher 3A current rating on the 2311771-1?

A: The substitute's 3A rating exceeds the original 2A specification. This represents an enhanced capability that maintains backward compatibility with applications designed for 2A operation while providing additional performance margin for higher-current applications.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity. The substitute includes a UL94 V-0 material flammability rating, which is an enhancement. No compliance restrictions exist for substitution.

Q: Why is the 5748394-5 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2311771-1 remains in active production, ensuring supply availability and ongoing technical support.

Q: What is the difference between the packaging specifications?

A: The main part lists packaging as unspecified, while the substitute is packaged in bulk. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and handling procedures.

Q: Are the contact materials compatible between the two parts?

A: Both parts feature gold-plated contacts with identical 30.0µin (0.76µm) finish thickness. The substitute specifies brass contact material, which is standard for this connector class and maintains full compatibility with mating components.

Q: Can the 2311771-1 operate across the same temperature range as the 5748394-5?

A: Yes. Both connectors are rated for -55°C to 105°C operation, ensuring identical thermal performance across all application environments.
