CD78P91C6GL00LF Equivalent & Substitute Parts

Part Overview

The CD78P91C6GL00LF is a 78-position D-Sub high-density plug connector manufactured by Amphenol ICC (FCI) with male pins and through-hole mounting. This connector is classified as obsolete, necessitating identification of active alternative components that maintain functional and electrical compatibility for applications requiring D-Sub high-density interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD78P91C6GL00LF is determined by the following critical parameters:

• Connector Style & Type: Must be D-Sub, high-density plug with male pins
• Position Count & Row Configuration: Must maintain 78 positions in 4-row arrangement
• Shell Size & Layout: Must conform to shell size 5 (DD, D) high-density specification
• Mounting Method: Must support through-hole mounting
• Contact Type: Must be signal-type contacts
• Mechanical Compatibility: Shell material and flange features must permit mating with corresponding receptacles

The substitute part 09565617713 (HARTING) satisfies these core substitution criteria. Variations in termination method (solder vs. press-fit), shell finish (nickel vs. tin), and contact finish specifications represent acceptable engineering trade-offs within the D-Sub high-density connector category, provided the mechanical and electrical envelope remains compatible.

Engineering Selection Recommendations

The HARTING 09565617713 connector is an active substitute for the obsolete CD78P91C6GL00LF. Selection of this alternative is supported by:

• Product Status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The HARTING part carries ROHS3 compliance and UL94 V-0 flammability certification, meeting modern regulatory requirements
• Mechanical Compatibility: Both connectors share identical shell size, position count, row configuration, and through-hole mounting, ensuring physical interchangeability with mating receptacles
• Electrical Performance: The substitute maintains signal-type contact configuration and operates within the voltage and current envelope of the original part, with the exception of a reduced current rating (2A vs. 2.5A) and narrower operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C)

Selection of the HARTING substitute is appropriate for applications where the narrower temperature range and reduced current rating do not conflict with system requirements, and where solder termination is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09565617713 directly replace the Amphenol ICC CD78P91C6GL00LF in existing designs?

A: Mechanical and electrical compatibility is confirmed for the core connector interface. The substitute maintains 78-position, 4-row, high-density D-Sub plug configuration with through-hole mounting. Verification is required for termination method compatibility (solder vs. press-fit) and operating temperature range applicability.

Q: What are the key differences between these two connectors?

A: Primary differences include termination method (solder vs. press-fit), shell finish (nickel vs. tin), current rating (2A vs. 2.5A), operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C), and regulatory certifications (ROHS3 and UL94 V-0 for the substitute).

Q: Is the reduced current rating of the HARTING connector a limitation?

A: The 2A rating of the HARTING connector is lower than the 2.5A rating of the original. Applications requiring current levels between 2A and 2.5A per contact must be evaluated against the substitute's specifications.

Q: Does the narrower operating temperature range of the substitute affect compatibility?

A: The HARTING connector operates from -40°C to 85°C, compared to -55°C to 125°C for the original. Applications requiring operation outside this range are not suitable for this substitute.

Q: What is the significance of the ROHS3 and UL94 V-0 certifications on the substitute?

A: ROHS3 compliance indicates restriction of hazardous substances per current EU regulations. UL94 V-0 flammability rating indicates the dielectric material meets stringent flame-retardant requirements. These certifications reflect current manufacturing and regulatory standards.

Q: Are there packaging differences between the original and substitute?

A: The original part packaging is not specified. The substitute is supplied in tray packaging. Packaging compatibility with assembly processes should be confirmed.
