Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 917780-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Number of positions (2)
• Pitch specification (0.098" / 2.50mm)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Current rating (3A)
• Voltage rating (50V)
• Operating temperature range (-30°C ~ 105°C)
• Flammability rating (UL94 V-0)
• Series designation (Signal Double Lock)

The 917780-1 satisfies all mandatory matching parameters and qualifies as a direct functional equivalent. Both parts share identical electrical and mechanical specifications within the Signal Double Lock series. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 917780-1 serves as the direct functional equivalent for the obsolete 917780-9. Both components are manufactured by TE Connectivity within the Signal Double Lock series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 917780-9 carries obsolete status, while the 917780-1 maintains active product status. This distinction reflects ongoing manufacturing availability and long-term supply chain viability.

Compliance Status: The 917780-1 is ROHS3 compliant, whereas the 917780-9 lists RoHS status as not applicable. For applications subject to RoHS directives, the 917780-1 provides documented compliance certification.

Inventory Availability: The 917780-1 demonstrates significantly higher inventory levels (11,361 pieces) compared to the 917780-9 (908 pieces), indicating superior procurement accessibility for new designs and production requirements.

Packaging Configuration: The 917780-1 is supplied in bulk packaging, whereas the 917780-9 packaging specification is not provided. Bulk packaging typically accommodates high-volume manufacturing operations and automated assembly processes.

For new designs, production continuity, or component replacement scenarios, the 917780-1 is the appropriate selection based on active product status, regulatory compliance, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Are the 917780-9 and 917780-1 electrically interchangeable?

A: Yes. Both components share identical electrical specifications: 3A current rating, 50V voltage rating, and -30°C to 105°C operating temperature range. They are electrically interchangeable within all general-purpose applications.

Q: Are the 917780-9 and 917780-1 mechanically interchangeable?

A: Yes. Both components feature identical mechanical specifications: 2-position configuration, 2.5mm pitch, through-hole mounting, shrouded 4-wall design, and 13.7mm mated stacking height. They are mechanically interchangeable in board-level applications.

Q: What is the significance of the product status difference between these parts?

A: The 917780-9 is classified as obsolete, indicating TE Connectivity no longer manufactures this variant. The 917780-1 maintains active status, ensuring continued manufacturing support and supply chain availability. For ongoing production and new designs, the active 917780-1 is the appropriate selection.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: The 917780-1 is ROHS3 compliant, while the 917780-9 lists RoHS status as not applicable. For applications subject to RoHS directives or regulatory requirements, the 917780-1 provides documented compliance. Both parts are functionally equivalent; compliance requirements determine which variant is appropriate for specific applications.

Q: What packaging differences exist between these parts?

A: The 917780-1 is supplied in bulk packaging, while the 917780-9 packaging specification is not provided. Bulk packaging is standard for high-volume manufacturing and automated assembly operations. Packaging selection depends on production volume and assembly methodology.

Q: Can the 917780-1 replace the 917780-9 in existing designs?

A: Yes. The 917780-1 is a direct functional equivalent with identical electrical and mechanical specifications. Existing designs using the 917780-9 can transition to the 917780-1 without circuit or layout modifications.

Q: Why is inventory availability different between these parts?

A: The 917780-1 (11,361 pieces) maintains significantly higher inventory than the 917780-9 (908 pieces) due to its active product status. Active products receive continuous manufacturing and distribution support, resulting in higher stock levels across distribution channels.

Q: Are there any performance differences between the 917780-9 and 917780-1?

A: No performance differences exist. Both components are manufactured to identical specifications within the Signal Double Lock series. Performance characteristics, including current handling, voltage rating, temperature range, and contact reliability, are equivalent.
