DBMM25PLF225 D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The DBMM25PLF225 is a 25-position D-Sub plug connector manufactured by ITT Cannon, LLC, featuring right-angle solder termination and panel mount through-hole installation. This connector is classified as an active product with full RoHS compliance and is designed for signal applications requiring reliable interconnection in industrial and electronic equipment.

Substitute parts are identified when equivalent connectors share the same core functional parameters: 25-position D-Sub plug configuration, male pin contact type, right-angle mounting orientation, solder termination method, and shell size 3 (DB, B) layout. Alternative sources become necessary for inventory availability, lead time optimization, or supply chain redundancy.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBMM25PLF225 is determined by strict alignment with the following mandatory parameters:

• Connector style: D-Sub configuration
• Connector type: Plug with male pins
• Position count: 25 positions
• Row configuration: 2 rows
• Shell size and layout: Size 3 (DB, B)
• Mounting method: Panel mount, through-hole, right-angle orientation
• Termination method: Solder
• Contact classification: Signal contacts
• Flange type: Unthreaded housing/shell
• Contact form: Machined contacts

The substitute part 174-E25-113R001 (NorComp Inc.) meets all mandatory substitution criteria. Both connectors share identical functional architecture, mechanical footprint compatibility, and electrical signal-handling classification. Differences in shell material finish, contact finish thickness specification, current rating, operating temperature range, and dielectric material do not preclude substitution when the primary requirement is mechanical and electrical connectivity within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the DBMM25PLF225 and 174-E25-113R001 are active products with current manufacturing status and full regulatory compliance. The DBMM25PLF225 offers a wider operating temperature range (-55°C to 150°C) and higher current rating (7.5A), making it suitable for applications requiring extended thermal performance. The 174-E25-113R001 operates within -50°C to 100°C with a 5A current rating and is packaged in trays for volume distribution.

Selection between these parts depends on application-specific requirements: choose the DBMM25PLF225 for high-temperature or high-current signal applications; select the 174-E25-113R001 when inventory availability or cost optimization is prioritized and operating conditions remain within its specified range. Both connectors satisfy UL94 V-0 flammability requirements and maintain gold-plated contact finishes for signal integrity.

Frequently Asked Questions (FAQ)

Q: Can the 174-E25-113R001 be used as a direct replacement for the DBMM25PLF225?

A: Yes, within the constraints of your application's operating temperature and current requirements. Both connectors share identical mechanical footprint, pin configuration (25 positions, 2 rows, size 3 DB shell), mounting method (right-angle panel mount through-hole), and termination approach (solder). Verify that your application operates within the 174-E25-113R001's temperature range (-50°C to 100°C) and current limit (5A).

Q: What are the differences in shell material between these two connectors?

A: The DBMM25PLF225 uses stainless steel shell material, while the 174-E25-113R001 uses nickel-plated steel. Both materials provide adequate shielding and mechanical protection for signal applications. Stainless steel offers superior corrosion resistance in harsh environments; nickel-plated steel is suitable for standard industrial conditions.

Q: How do the operating temperature ranges affect substitution?

A: The DBMM25PLF225 operates from -55°C to 150°C, while the 174-E25-113R001 operates from -50°C to 100°C. If your application requires operation below -50°C or above 100°C, the DBMM25PLF225 is the appropriate choice. For applications within -50°C to 100°C, both connectors are functionally equivalent.

Q: Are there current rating implications for substitution?

A: The DBMM25PLF225 is rated for 7.5A, while the 174-E25-113R001 is rated for 5A. If your application requires current handling above 5A per contact, use the DBMM25PLF225. For applications at or below 5A, both connectors are suitable.

Q: What is the significance of contact finish thickness differences?

A: The DBMM25PLF225 specifies 50.0µin (1.27µm) gold plating, while the 174-E25-113R001 specifies flash gold plating. Both provide adequate contact resistance and signal integrity for D-Sub connector applications. Thicker plating on the DBMM25PLF225 may offer extended contact life in high-cycle mating applications.

Q: Do packaging differences affect technical compatibility?

A: No. The 174-E25-113R001 is supplied in trays, while the DBMM25PLF225 packaging is not specified. Packaging affects logistics and handling only; it does not alter electrical or mechanical compatibility.

Q: Are both connectors RoHS compliant?

A: Yes. The DBMM25PLF225 is RoHS Compliant, and the 174-E25-113R001 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions for electronic components.
