DBML25S043 Equivalent & Substitute Parts

Part Overview

The DBML25S043 is a 25-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) with solder cup termination and cable-side mounting. This connector is designed for harsh environment applications with UL94 V-0 flammability rating and operates across -55°C to 125°C. The part is currently active in production. Substitute parts may be required due to supply chain considerations, obsolescence of alternative designs, or specific application requirements related to mounting configuration or compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBML25S043 is determined by the following critical parameters:

• Connector Style & Type: Must be D-Sub receptacle with female sockets
• Position Count & Row Configuration: Must maintain 25 positions in 2-row layout
• Shell Size: Must be Size 3 (DB, B)
• Termination Method: Must use solder cup termination
• Contact Finish: Must be gold-plated
• Flammability Rating: Must meet UL94 V-0
• Electrical Ratings: Current and voltage ratings must meet or exceed 7.5A and 300V respectively

The substitute parts identified (172-025-202R001 and 172-025-202R011, both from NorComp Inc.) share the core D-Sub receptacle architecture, 25-position configuration, and solder cup termination. However, these substitutes differ in mounting type (panel mount versus cable-side free hanging) and current rating (5A versus 7.5A), which may affect suitability depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

172-025-202R001 (NorComp Inc.): This substitute is electrically compatible for applications not requiring the full 7.5A current capacity of the DBML25S043. The 5A rating is suitable for lower-power signal applications. The part is ROHS3 compliant, providing regulatory advantage over the non-compliant DBML25S043. However, this part is obsolete and features panel mount configuration rather than cable-side free hanging, requiring mechanical redesign of the installation. Operating temperature range is reduced to -50°C ~ 100°C.

172-025-202R011 (NorComp Inc.): This substitute maintains cable-side mounting via 4-40 fasteners, closer to the DBML25S043 mounting approach. Like 172-025-202R001, it carries 5A current rating and ROHS3 compliance. This part is also obsolete with reduced operating temperature range (-50°C ~ 100°C). The 4-40 cable-side flange differs from the M3 specification on the DBML25S043.

Selection between substitutes depends on application current requirements and mechanical mounting constraints. Both NorComp substitutes are obsolete, indicating limited future availability.

Frequently Asked Questions (FAQ)

Q: Can 172-025-202R001 or 172-025-202R011 be used as direct replacements for DBML25S043?

A: Both parts share the core D-Sub 25-position receptacle architecture and solder cup termination. However, direct replacement requires evaluation of three factors: (1) Current capacity—substitutes are rated 5A versus DBML25S043 at 7.5A; (2) Mounting configuration—DBML25S043 uses cable-side M3 mounting while 172-025-202R001 is panel mount and 172-025-202R011 uses cable-side 4-40 fasteners; (3) Operating temperature—substitutes operate -50°C ~ 100°C versus DBML25S043 at -55°C ~ 125°C.

Q: What are the key electrical compatibility criteria?

A: All three parts maintain 25-position D-Sub receptacle configuration with gold-plated contacts and UL94 V-0 flammability rating. Voltage rating is specified as 300V for DBML25S043; voltage ratings are not specified for the NorComp substitutes. Current capacity differs: DBML25S043 at 7.5A versus NorComp parts at 5A.

Q: How do the mounting configurations differ?

A: DBML25S043 features cable-side free hanging (in-line) mounting with M3 flange. 172-025-202R001 is panel mount with unthreaded housing flange. 172-025-202R011 is panel mount with cable-side 4-40 fastener flange. Mounting type selection depends on PCB or chassis integration requirements.

Q: What is the significance of RoHS compliance differences?

A: DBML25S043 is RoHS non-compliant. Both NorComp substitutes (172-025-202R001 and 172-025-202R011) are ROHS3 compliant. For applications subject to RoHS regulations, the NorComp parts provide regulatory compliance advantage.

Q: Are these parts interchangeable from a packaging perspective?

A: All three parts are supplied in tray packaging. Mechanical interchangeability depends on mounting type and flange configuration as described above. Electrical interchangeability is limited by current rating differences.

Q: What is the product status significance?

A: DBML25S043 is active in production. Both NorComp substitutes are obsolete, indicating discontinued manufacturing and potential supply constraints for future procurement.
