Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7-104430-7 with the 9-102974-0 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Identical pitch specification: 0.100" (2.54mm)
• Identical number of positions: 40
• Identical number of rows: 1
• Identical contact type: Male Pin
• Identical current rating: 3A
• Identical operating temperature range: -65°C ~ 105°C

Mechanical Compatibility Parameters:

• Identical connector type: Header, Breakaway
• Identical mounting type: Through Hole, Right Angle
• Identical contact shape: Square
• Identical insulation material: Thermoplastic
• Identical insulation height: 0.138" (3.50mm)
• Identical contact length - mating: 0.318" (8.08mm)
• Identical contact length - post: 0.110" (2.79mm)

Material & Finish Parameters:

• Identical contact material: Copper Alloy
• Identical contact finish - mating: Gold at 15.0µin (0.38µm)
• Identical contact finish - post: Tin at 100.0µin (2.54µm)
• Identical insulation color: Black

Compliance Parameters:

• Both RoHS Compliant (7-104430-7: RoHS Compliant; 9-102974-0: ROHS3 Compliant)
• Both UL94 V-0 rated
• Both MSL 1 (Unlimited)
• Both ECCN EAR99 classification

The substitute part 9-102974-0 differs only in product status (Active vs. Obsolete) and termination specification (Solder only vs. Press-Fit and Solder), with the latter representing a subset of the original part's termination options.

Parameter Comparison

Engineering Selection Recommendations

The 9-102974-0 serves as the direct functional equivalent to the obsolete 7-104430-7. Selection of the substitute part is supported by the following engineering criteria:

Compliance & Certification Alignment: The substitute part maintains identical UL94 V-0 flammability rating and achieves enhanced RoHS compliance status (ROHS3 vs. RoHS Compliant), ensuring compatibility with current regulatory requirements. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN/HTSUS designations.

Electrical & Mechanical Equivalence: All critical electrical parameters remain unchanged: 40-position, single-row configuration at 0.100" (2.54mm) pitch with 3A current rating and -65°C to 105°C operating temperature range. Mechanical dimensions, contact geometry, and mounting specifications are identical, ensuring direct board-level compatibility without design modification.

Termination Compatibility: The substitute part specifies Solder termination only, compared to the original part's Press-Fit and Solder options. For applications utilizing solder termination exclusively, this represents full functional equivalence. Applications requiring press-fit termination capability must retain the original part number or identify alternative solutions.

Product Status Advantage: The active product status of 9-102974-0 provides assured long-term availability and supply chain continuity, addressing the obsolescence constraint of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 9-102974-0 be used as a direct replacement for the 7-104430-7 in all applications?

A: The 9-102974-0 provides direct functional replacement for applications utilizing solder termination. The original part supports both press-fit and solder termination options. If your application requires press-fit termination capability, the substitute part does not support this option and alternative solutions must be evaluated.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications: 40 positions, 0.100" (2.54mm) pitch, 3A current rating, and -65°C to 105°C operating temperature range. Voltage rating is not specified for the substitute part; however, all other electrical parameters are equivalent.

Q: What is the significance of the RoHS compliance difference?

A: The substitute part carries ROHS3 compliance, representing current regulatory alignment. The original part carries RoHS Compliant status. Both designations indicate compliance with Restriction of Hazardous Substances requirements. ROHS3 represents the most current compliance standard and is preferred for new designs and long-term supply assurance.

Q: Are the physical dimensions and contact specifications identical?

A: Yes. Contact length (mating and post), insulation height, contact shape, contact finish specifications, and all mechanical dimensions are identical between both parts. Board-level compatibility is maintained without modification.

Q: What packaging differences exist between these parts?

A: The original part 7-104430-7 packaging specification is not provided. The substitute part 9-102974-0 is supplied in Bulk packaging. Confirm packaging requirements for your application before procurement.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 9-102974-0 maintains active status, ensuring continued availability and support. For new designs and ongoing production, the active substitute part is the recommended selection.

Q: Are there inventory considerations for these parts?

A: The original part 7-104430-7 shows 705 pieces in stock. The substitute part 9-102974-0 shows 1812 pieces in stock, providing greater availability. For long-term supply planning, the active substitute part offers superior supply chain assurance.

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

A: Yes, for applications utilizing solder termination. Both parts feature identical mounting type (through-hole, right-angle), contact configuration, and board interface specifications. No PCB design modification is required for substitution in solder-termination applications.
