Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 747916-4 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain identical specifications in the following categories:

Electrical Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (37)
• Number of rows (2)
• Shell size and layout (4, DC, C)
• Current rating (3A)
• Voltage rating (250V)
• Contact finish (Gold) and thickness (8.00µin)

Mechanical Parameters:

• Connector style (D-Sub)
• Termination method (Solder Cup)
• Mounting type (Free Hanging, In-Line)
• Dielectric material (PBT, Glass Filled)
• Flammability rating (UL94 V-0)

Environmental Parameters:

• Operating temperature range (-55°C to 105°C)

Parts meeting these criteria are classified as direct substitutes. Variations in shell finish material, packaging format, or product status do not affect functional interchangeability when all electrical and mechanical parameters remain constant.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-747916-2

The 5-747916-2 is the recommended direct substitute for the obsolete 747916-4. Both parts are manufactured by TE Connectivity within the AMPLIMITE HD-20 series and maintain identical electrical and mechanical specifications across all critical parameters. The 5-747916-2 is classified as an active product with current production status, ensuring ongoing availability and supply chain support.

The 5-747916-2 carries RoHS Compliant certification, whereas the 747916-4 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. The shell finish differs (tin plated versus blue zinc plated), but this variation does not affect electrical performance or mechanical interchangeability.

Secondary Substitute: JAE Electronics DC-37PF-N

The DC-37PF-N from JAE Electronics is a similar substitute offering the same 37-position D-Sub plug configuration with solder cup termination. This part provides an alternative sourcing option from a different manufacturer. However, complete parameter specifications for the DC-37PF-N are not fully documented in available data. Selection of this part requires confirmation that all unspecified parameters align with the 747916-4 requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 5-747916-2 be used as a direct replacement for the 747916-4 in existing designs?

A: Yes. The 5-747916-2 maintains identical electrical and mechanical specifications with the 747916-4 across all critical parameters including connector type, position count, termination method, current and voltage ratings, operating temperature range, and dielectric properties. The difference in shell finish material (tin plated versus blue zinc plated) does not affect functional interchangeability.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 747916-4 is RoHS non-compliant while the 5-747916-2 is RoHS Compliant. RoHS compliance is a regulatory requirement in many jurisdictions for electrical and electronic equipment. Applications subject to RoHS regulations must use the 5-747916-2 or equivalent RoHS-compliant alternatives. Non-regulated applications may use either part based on availability and supply chain considerations.

Q: Are there packaging differences between the 747916-4 and 5-747916-2?

A: The 5-747916-2 is supplied in tray packaging, while packaging information for the 747916-4 is not specified. Packaging format does not affect connector performance or interchangeability. Selection between these parts should consider procurement requirements, inventory management practices, and handling procedures specific to your manufacturing environment.

Q: What parameters must remain constant for a part to be considered a substitute for the 747916-4?

A: Substitute parts must maintain equivalence in connector type (Plug, Male Pins), position count (37), row configuration (2), shell size (4, DC, C), termination method (Solder Cup), current rating (3A), voltage rating (250V), contact finish (Gold, 8.00µin thickness), dielectric material (PBT, Glass Filled), flammability rating (UL94 V-0), and operating temperature range (-55°C to 105°C). Variations in shell finish material or packaging do not affect substitutability.

Q: Is the DC-37PF-N from JAE Electronics a suitable substitute?

A: The DC-37PF-N provides the same 37-position D-Sub plug configuration with solder cup termination. However, complete technical specifications for this part are not fully documented. Before selecting the DC-37PF-N, confirm that all unspecified parameters including shell size layout, mounting type, contact finish thickness, current rating, voltage rating, operating temperature range, dielectric material, and flammability rating match the 747916-4 requirements.

Q: Why is the 747916-4 classified as obsolete?

A: The 747916-4 is no longer in active production. The 5-747916-2 represents the current active product offering from TE Connectivity for this connector configuration. Transitioning to the 5-747916-2 ensures access to current manufacturing, quality assurance, and supply chain support.
