Key Parameters

Substitute Part Grouping Explanation

The substitute parts D09P91C4GV00LF and D09P91C6GV00LF are classified as equivalent alternatives based on the following critical parameters:

Matching Parameters:

• Connector style: D-Sub
• Position count: 9 positions, 2 rows
• Shell size and layout: 1 (DE, E)
• Mounting type: Through hole
• Termination: Press-fit
• Voltage rating: 300V
• Operating temperature: -55°C ~ 125°C
• Material flammability: UL94 V-0
• RoHS compliance: Yes
• Moisture sensitivity level: 1 (Unlimited)

Functional Difference: The substitute parts are plug connectors (male pins) rather than receptacle connectors (female sockets). This represents a complementary mating pair relationship within the D-Sub connector family. Both substitute parts share identical shell geometry, position count, and electrical ratings with the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L17TF0901111): Select this receptacle connector when the application requires female socket termination on the printed circuit board. The part maintains active product status with full RoHS compliance and unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

Substitute Part Selection (D09P91C4GV00LF or D09P91C6GV00LF): These plug connectors serve as mating partners to receptacle connectors in complete D-Sub assemblies. Selection between the two substitute parts depends on contact finish thickness requirements. D09P91C6GV00LF provides thicker gold plating (30.0µin) compared to D09P91C4GV00LF (flash thickness), offering enhanced contact durability in high-cycle mating applications. Both substitute parts support higher current ratings (5A per contact) relative to the main part (3A).

All three parts maintain identical electrical ratings (300V), temperature operating range (-55°C ~ 125°C), and compliance certifications (RoHS, UL94 V-0, MSL 1). Interchangeability is determined by connector gender (male versus female) and specific application requirements for current capacity and contact finish specifications.

Frequently Asked Questions (FAQ)

Q: Can D09P91C4GV00LF or D09P91C6GV00LF be used as direct replacements for L17TF0901111?

A: No. The substitute parts are plug connectors (male pins) while L17TF0901111 is a receptacle connector (female sockets). They are complementary mating components, not direct replacements. Use substitute parts when designing the mating connector assembly.

Q: What is the difference between D09P91C4GV00LF and D09P91C6GV00LF?

A: Both parts are identical plug connectors with the same electrical and mechanical specifications. The primary difference is contact finish thickness: D09P91C4GV00LF has flash gold plating, while D09P91C6GV00LF has 30.0µin (0.76µm) gold plating. Select D09P91C6GV00LF for applications requiring enhanced contact durability.

Q: Are all three parts RoHS compliant?

A: Yes. L17TF0901111, D09P91C4GV00LF, and D09P91C6GV00LF are all RoHS compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the current rating difference between the main part and substitute parts?

A: L17TF0901111 is rated for 3A total current. D09P91C4GV00LF and D09P91C6GV00LF are each rated for 5A per contact. Select substitute parts for applications requiring higher per-contact current capacity.

Q: Do all parts operate in the same temperature range?

A: Yes. All three parts operate across -55°C to 125°C, with identical UL94 V-0 flammability ratings.

Q: What shell size and position configuration do these connectors use?

A: All three parts use shell size 1 (DE, E) with 9 positions arranged in 2 rows, conforming to standard D-Sub geometry specifications.

Q: Are the dielectric materials the same across all parts?

A: No. L17TF0901111 uses thermoplastic glass-filled dielectric material, while D09P91C4GV00LF and D09P91C6GV00LF use polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements.
