D37P91C6PI9CLF Equivalent & Substitute Parts

Part Overview

The D37P91C6PI9CLF is a 37-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features male pins with press-fit termination and is designed for signal applications requiring robust mechanical and electrical performance. The connector is actively produced and RoHS compliant, making it suitable for industrial and commercial applications where D-Sub connectivity is required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints necessitate qualified alternatives.

Substitute Part Grouping Explanation

The D37P91C6PI9CLF has one qualified substitute: TE Connectivity AMP Connectors part number 5788458-1. Substitution eligibility is determined by the following critical parameters:

Connector Configuration: Both parts are 37-position D-Sub plugs with male pins in a 2-row arrangement
Shell Size and Layout: Both use shell size 4 (DC, C) configuration
Mounting and Termination: Both employ through-hole mounting with press-fit termination
Shell Material and Finish: Both feature steel shells with tin plating
Contact Finish: Both provide gold-plated contacts
Flammability Rating: Both meet UL94 V-0 material flammability requirements
RoHS Compliance: Both are RoHS compliant (main part: RoHS Compliant; substitute: ROHS3 Compliant)
Grounding Features: Both include grounding indents

The substitute part 5788458-1 from the AMPLIMITE HD-20 series maintains functional and mechanical compatibility with the original D37P91C6PI9CLF, enabling direct substitution in applications where these core parameters are required.

Engineering Selection Recommendations

Both the D37P91C6PI9CLF and 5788458-1 are active production parts with current inventory availability. The D37P91C6PI9CLF maintains RoHS compliance status, while the substitute 5788458-1 carries ROHS3 compliance, indicating adherence to the most current RoHS directive requirements. Both connectors meet UL94 V-0 flammability standards and share identical electrical and mechanical specifications for the critical parameters governing D-Sub plug functionality: 37-position configuration, shell size 4 layout, press-fit termination, and gold-plated contacts.

Selection between these parts should be based on inventory availability, lead time requirements, and supply chain considerations. The substitute part 5788458-1 from TE Connectivity's AMPLIMITE HD-20 series provides equivalent performance and compatibility for applications currently using the Amphenol ICC Delta D series connector.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5788458-1 be used as a direct replacement for the Amphenol ICC D37P91C6PI9CLF?

A: Yes. Both connectors share identical core specifications: 37-position D-Sub plug configuration, shell size 4 (DC, C) layout, through-hole mounting, press-fit termination, steel tin-plated shells, and gold-plated contacts. Mechanical and electrical compatibility is maintained across all critical parameters.

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

A: The primary differences are manufacturer identity and series designation. The D37P91C6PI9CLF is from Amphenol ICC's Delta D series, while 5788458-1 is from TE Connectivity's AMPLIMITE HD-20 series. The substitute carries ROHS3 compliance versus RoHS compliance on the original part. No functional or mechanical differences exist in the parameters provided.

Q: Are there any packaging differences between these connectors?

A: Yes. The D37P91C6PI9CLF is supplied in Tray packaging, while the 5788458-1 is supplied in Bulk packaging. This distinction affects handling and storage procedures but does not impact connector performance or compatibility.

Q: Do both connectors meet the same environmental and compliance standards?

A: Both connectors meet UL94 V-0 flammability requirements, carry MSL 1 (Unlimited) moisture sensitivity ratings, and are classified as EAR99 for export control purposes. Both share the same HTSUS tariff code (8536.69.4040). The substitute part carries updated ROHS3 compliance status.

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

A: The D37P91C6PI9CLF operates from -55°C to 125°C. Operating temperature data for the substitute part 5788458-1 was not provided in the specification parameters.

Q: Are these connectors suitable for high-current applications?

A: The D37P91C6PI9CLF is rated for 5A current and 300V voltage. Current and voltage ratings for the substitute part 5788458-1 were not provided in the specification parameters. Application requirements should be evaluated against the available electrical ratings.
