Electrical Compatibility Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 20
• Number of rows: 2
• Shell size and connector layout: 0.050 Pitch x 0.100 Row to Row
• Current rating: 1A
• Voltage rating: 30V
• Operating temperature range: -55°C ~ 105°C
• Contact material: Phosphor Bronze
• Contact finish: Gold

Mechanical Compatibility Parameters:

• Mounting type: Through Hole
• Termination method: Press-Fit
• Shell material and finish: Steel, Nickel Plated
• Dielectric material: Polyphthalamide (PPA)
• Flange feature: Housing/Shell (2-56); Latchblocks, Rails
• Shielded construction

Series and Category:

• Series: AMPLIMITE .050 III
• Category: D-Sub, D-Shaped Connectors

Parts meeting all these parameters are classified as direct equivalents and may be substituted without modification to the circuit design or mechanical assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the 786554-1 and 5786554-1 are functionally equivalent D-Type receptacle connectors with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

Compliance Requirements: The 5786554-1 carries RoHS Compliant status and REACH Unaffected designation, making it suitable for applications with regulatory compliance mandates. The 786554-1 is marked as Not applicable for RoHS status and REACH Affected, indicating it may be subject to regulatory restrictions in certain jurisdictions or end-use applications.

Product Status: Both parts maintain Active product status, confirming ongoing manufacturer support and availability.

Inventory Availability: The 5786554-1 offers higher inventory availability with 1684 units in stock compared to 693 units for the 786554-1. This may influence lead time and supply chain planning.

Application Suitability: For applications requiring RoHS compliance or REACH compliance documentation, the 5786554-1 is the appropriate selection. For applications without such regulatory requirements, either part is suitable based on availability and delivery schedule.

Frequently Asked Questions (FAQ)

Q: Are the 786554-1 and 5786554-1 directly interchangeable?

A: Yes. Both connectors are 20-position D-Type receptacles with identical electrical ratings (1A, 30V), mechanical specifications (through-hole, press-fit termination), and physical dimensions (0.050 Pitch x 0.100 Row to Row). They belong to the same AMPLIMITE .050 III series and feature identical contact materials, shell finishes, and dielectric properties.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications and inventory levels. The 5786554-1 is RoHS Compliant and REACH Unaffected, while the 786554-1 is marked as Not applicable for RoHS and REACH Affected. The 5786554-1 has higher stock availability (1684 units versus 693 units).

Q: Can I use the 5786554-1 as a replacement for the 786554-1 in an existing design?

A: Yes. The 5786554-1 is a direct functional equivalent with no design modifications required. The connector will mate with the same mating plugs and perform identically in the circuit.

Q: Which part should I specify for a new design?

A: If your application requires RoHS compliance or REACH compliance documentation, specify the 5786554-1. If no regulatory compliance is mandated, either part is suitable. Consider inventory availability and lead time requirements when making the final selection.

Q: Are the packaging specifications identical?

A: Yes. Both parts are supplied in tube packaging, consistent with standard handling and storage requirements for D-Type connectors.

Q: What is the operating temperature range for these connectors?

A: Both the 786554-1 and 5786554-1 operate across the temperature range of -55°C to 105°C, suitable for industrial and commercial applications.

Q: Do these connectors support shielded applications?

A: Yes. Both connectors feature shielded construction, providing electromagnetic interference protection for signal integrity in sensitive applications.
