Key Parameters

Substitute Part Grouping Explanation

Substitution of the 747904-8 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (9)
• Shell size and layout (1 / DE, E)
• Current rating (3A)
• Voltage rating (250V)
• Contact finish (Gold)
• Dielectric material (Polybutylene Terephthalate, Glass Filled)

Mechanical Compatibility Parameters:

• Termination method (Solder Cup)
• Mounting type (Free Hanging, In-Line)
• Flange feature (Cable Side, 4-40)
• Shell material and finish (Steel, Tin Plated)
• Operating temperature range (-55°C to 105°C)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

The substitute part 5-747904-8 maintains identical electrical and mechanical specifications across all parameters listed above. The primary distinction is product status (Active versus Obsolete) and packaging configuration (Bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-747904-8 is functionally and mechanically equivalent to the obsolete 747904-8 across all electrical and mechanical parameters. Selection between these parts is determined by application requirements and regulatory compliance:

For applications requiring RoHS3 compliance: The 5-747904-8 is the appropriate selection, as it carries ROHS3 Compliant certification. The original 747904-8 is RoHS non-compliant and unsuitable for regulated environments.

For applications without RoHS compliance requirements: Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. The 5-747904-8 remains the preferred choice due to active product status and superior inventory availability (6806 units versus 686 units).

For procurement planning: The 5-747904-8 is available in bulk packaging, which accommodates high-volume manufacturing and assembly operations. The original part number is classified as obsolete and subject to discontinuation.

Both parts operate within the identical temperature range (-55°C to 105°C), maintain the same current and voltage ratings (3A, 250V), and employ identical contact materials and finishes. No performance degradation or functional limitation occurs when substituting 5-747904-8 for 747904-8 in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 5-747904-8 be used as a direct replacement for the 747904-8 in existing assemblies?

A: Yes. The 5-747904-8 maintains identical electrical and mechanical specifications across all parameters including connector type, pin count, shell size, termination method, current rating, voltage rating, and operating temperature range. No design modification is required.

Q: What is the difference between the 747904-8 and 5-747904-8?

A: The primary differences are product status (Obsolete versus Active), RoHS compliance (non-compliant versus ROHS3 Compliant), and packaging configuration (standard versus bulk). All electrical and mechanical parameters are identical.

Q: Why is the 747904-8 classified as obsolete?

A: The 747904-8 is listed as obsolete by the manufacturer. The active equivalent 5-747904-8 is available for new designs and ongoing procurement.

Q: Does the RoHS3 compliance of the 5-747904-8 affect its electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics.

Q: Are there any temperature or current rating differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 105°C) and carry the same current rating (3A) and voltage rating (250V).

Q: What is the inventory status of each part?

A: The 747904-8 has 686 units in stock. The 5-747904-8 has 6806 units in stock, providing significantly greater availability for procurement.

Q: Can these connectors be used interchangeably in mating applications?

A: Yes. Both parts employ identical shell size (1 / DE, E), pin configuration (9 positions, 2 rows), and flange specifications (Cable Side, 4-40). They mate with the same receptacle connectors.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold contact finish with 8.00µin (0.203µm) thickness, ensuring consistent electrical performance and corrosion resistance.
