• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Current rating (3A)
• Voltage rating (30VAC)
• Operating temperature range (-65°C ~ 105°C)

Mechanical Parameters:

• Connector type (Header, Breakaway)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Insulation height (0.238" / 6.05mm)
• Contact length specifications (Mating: 0.318" / 8.08mm; Post: 0.110" / 2.79mm)

Compliance Parameters:

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

The substitute part 7-104437-0 maintains full equivalence across all critical electrical and mechanical parameters. Differences in product status, contact finish composition, and packaging format do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The 7-104437-0 serves as a direct functional equivalent to the obsolete 2-104437-0 across all critical electrical and mechanical parameters. Both connectors maintain identical specifications for position count, pitch spacing, current and voltage ratings, operating temperature range, and physical dimensions.

The primary distinction between these parts is product status: the 2-104437-0 is obsolete, while the 7-104437-0 maintains active production status. This status difference ensures ongoing availability and supply chain continuity for the 7-104437-0.

An additional advantage of the 7-104437-0 is its RoHS compliance status. The substitute part meets RoHS requirements, whereas the main part does not. This compliance improvement may be beneficial for applications subject to RoHS regulations or environmental standards.

Contact finish composition differs between the two parts: the main part features Tin-Lead plating, while the substitute uses Tin plating. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and provide functionally equivalent electrical and mechanical performance within the specified operating parameters.

Packaging format differs, with the 7-104437-0 supplied in Tray format. This packaging difference does not affect connector functionality or interchangeability.
