D25P90C6GL00 D-Sub 25 Position Plug Connector Equivalent & Substitute Parts

Part Overview

The D25P90C6GL00 is a 25 position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the Delta D series. This connector features male pins, through-hole mounting, and press-fit termination with a steel tin-plated shell and gold-plated contacts. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the D25P90C6GL00 is determined by the following critical parameters:

Connector Type: Must be Plug with Male Pins
Position Count: Must be 25 positions
Shell Size: Must be 3 (DB, B)
Mounting Type: Must be Through Hole
Termination Method: Must be Press-Fit
Electrical Ratings: Current and voltage ratings must meet or exceed 5A and 300V respectively
Operating Temperature Range: Must support -55°C to 125°C minimum
Flammability: Must maintain UL94 V-0 rating

Substitute parts are grouped into two categories: direct functional equivalents from Amphenol ICC with improved compliance status, and cross-manufacturer alternatives from NorComp Inc. and TE Connectivity that maintain core electrical and mechanical compatibility while offering different shell finish and contact material specifications.

Engineering Selection Recommendations

D25P90C6GL00LF (Amphenol ICC FCI) is the primary direct substitute. It maintains identical electrical specifications, operating temperature range, and mechanical compatibility while offering RoHS compliance and improved shell finish (tin-nickel plating). This part is recommended for applications requiring regulatory compliance and long-term supply chain stability.

5748146-6 (TE Connectivity AMPLIMITE HD-20) provides functional equivalence with through-hole mounting and press-fit termination. The operating temperature range is reduced to -55°C to 105°C, making it suitable for standard industrial applications but not for extended temperature environments. RoHS3 compliance is available.

L17TF2511101 (Amphenol ICC Commercial Products TF series) offers RoHS compliance and maintains the full -55°C to 125°C operating range. Current rating is specified at 3A, which is lower than the original 5A specification. This part is suitable for lower-current signal applications.

191-025-123R001 (NorComp Inc.) is a panel-mount variant with different flange configuration (unthreaded housing). This part is not recommended as a direct substitute due to mounting type incompatibility with through-hole PCB designs.

5748146-4 (TE Connectivity AMPLIMITE HD-20) provides similar electrical and mechanical characteristics to 5748146-6 with identical temperature limitations and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can D25P90C6GL00LF be used as a direct replacement for D25P90C6GL00?

A: Yes. D25P90C6GL00LF maintains identical connector type, position count, shell size, mounting type, termination method, current rating (5A per contact), voltage rating (300V), and operating temperature range (-55°C to 125°C). The primary differences are shell finish (tin-nickel vs. tin plating) and RoHS compliance status (compliant vs. non-compliant).

Q: What is the current rating limitation when using L17TF2511101?

A: L17TF2511101 is rated at 3A per contact, compared to the original 5A specification. Applications requiring the full 5A current capacity should use D25P90C6GL00LF, 5748146-4, or 5748146-6 instead.

Q: Are TE Connectivity parts suitable for high-temperature applications?

A: TE Connectivity parts 5748146-4 and 5748146-6 operate from -55°C to 105°C, which is 20°C lower than the original specification of -55°C to 125°C. For applications requiring the full temperature range, use D25P90C6GL00LF or L17TF2511101.

Q: Why is 191-025-123R001 listed as a substitute if it has panel mount?

A: 191-025-123R001 is listed in the manufacturer's cross-reference data but has panel mount configuration versus through-hole mounting of the original part. It is not recommended for direct PCB mounting applications.

Q: What packaging options are available?

A: D25P90C6GL00LF is supplied in tray packaging. L17TF2511101 is supplied in tray packaging. TE Connectivity parts (5748146-4 and 5748146-6) are supplied in bulk packaging. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: D25P90C6GL00LF, 5748146-4, 5748146-6, and L17TF2511101 are all RoHS compliant (either RoHS or ROHS3). The original D25P90C6GL00 is RoHS non-compliant. 191-025-123R001 is ROHS3 compliant.
