D50P91C6GL00 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The D50P91C6GL00 is a 50-position D-Sub plug connector with male pins, manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features press-fit termination, gold-plated contacts, and a tin-plated steel shell rated for 5A at 300V operation across -55°C to 125°C.

The D50P91C6GL00 is classified as obsolete. Locating active production alternatives is necessary to ensure supply chain continuity and support for new designs or replacement requirements in existing applications.

Substitute Part Grouping Explanation

The D50P91C6GL00 has one direct substitute within the same manufacturer series: D50P91C6GL00LF. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector type, style, and pin count (50-position D-Sub plug, male pins)
• Shell size and layout (Size 5, DD/D configuration)
• Mounting method (through-hole)
• Termination technology (press-fit)
• Electrical ratings (5A, 300V)
• Operating temperature range (-55°C ~ 125°C)
• Contact and shell materials and finishes (gold-plated contacts, tin-plated steel shell)
• Dielectric and contact material composition (PBT, phosphor bronze)
• Mechanical features (board lock, grounding indents, M3 flange)

The substitute part maintains identical electrical, mechanical, and material specifications while differing in product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The D50P91C6GL00LF is the direct functional equivalent of the D50P91C6GL00. Both parts are electrically and mechanically identical across all specified parameters. The primary distinctions are:

Product Status: The D50P91C6GL00 is obsolete, while D50P91C6GL00LF is active production. For new designs or long-term supply requirements, D50P91C6GL00LF is the appropriate selection.

RoHS Compliance: The D50P91C6GL00LF meets RoHS requirements, whereas the D50P91C6GL00 does not. Applications subject to RoHS regulations or environmental compliance mandates require the D50P91C6GL00LF variant.

Packaging: The D50P91C6GL00LF is supplied in tray packaging, which may differ from the bulk packaging of the original part. Verify packaging compatibility with assembly and handling processes.

Both parts share identical electrical performance, mechanical fit, and material composition, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can D50P91C6GL00LF replace D50P91C6GL00 in existing designs?

A: Yes. The parts are electrically and mechanically equivalent across all specified parameters, including pin count, shell size, current and voltage ratings, operating temperature range, contact materials, and mechanical features. Direct substitution is supported.

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

A: The D50P91C6GL00LF is the active production variant with RoHS compliance and tray packaging. The D50P91C6GL00 is obsolete and RoHS non-compliant. Functional performance is identical.

Q: Why is the original part marked obsolete?

A: The D50P91C6GL00 has been superseded by the D50P91C6GL00LF in the manufacturer's product line. The newer variant maintains full compatibility while offering RoHS compliance and active supply status.

Q: Does packaging affect electrical or mechanical performance?

A: No. Packaging differences (bulk versus tray) do not affect connector performance. Verify that tray packaging is compatible with your assembly and storage processes.

Q: Are there any certifications or compliance differences?

A: Both parts carry UL94 V-0 flammability certification. The D50P91C6GL00LF additionally meets RoHS compliance requirements. Applications requiring RoHS certification must use D50P91C6GL00LF.

Q: What is the contact finish thickness, and does it affect substitution?

A: Both parts feature gold contact plating at 30.0µin (0.76µm) thickness. This specification is identical and does not affect substitution eligibility.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operation from -55°C to 125°C. Applications within this range are fully supported by either part.
