DSS3XPRAA15X Equivalent & Substitute Parts

Part Overview

The DSS3XPRAA15X is a 25-position D-Sub plug connector manufactured by Amphenol CONEC, featuring male pins with vertical solder termination and board-side flange mounting. This connector is designed for through-hole PCB applications requiring signal transmission in industrial and commercial electronics. The part maintains Active product status with 748 units in current inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where connector form factor, pin count, termination method, and mounting compatibility are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DSS3XPRAA15X is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Termination: Solder
• Flange Feature: Board Side (4-40)
• Contact Type: Signal
• Contact Finish: Gold
• Contact Material: Copper Alloy
• Material Flammability Rating: UL94 V-0

The substitute part DBMV25PNK87 (ITT Cannon, LLC) satisfies all critical matching parameters. Variations in shell material finish (Tin-Nickel versus Tin Plated), dielectric material composition (PCT versus PBT Glass Filled), and additional features (Grounding Indents present in both; Board Lock present only in main part) do not preclude substitution when the core electrical and mechanical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

DSS3XPRAA15X (Amphenol CONEC) is the primary specification when:

• Original equipment manufacturer (OEM) part traceability is required
• Board Lock feature integration is specified in the design
• PBT Glass Filled dielectric material is explicitly required
• ROHS3 Compliant certification is mandated

DBMV25PNK87 (ITT Cannon, LLC) is an acceptable substitute when:

• Functional equivalence in 25-position D-Sub plug configuration is the primary requirement
• RoHS Compliant status satisfies regulatory requirements
• Panel Mount capability provides additional mounting flexibility
• Operating temperature range (-55°C ~ 125°C) and current rating (7.5A) meet application demands
• PCT dielectric material is compatible with application environment
• Tin-Nickel plated steel shell provides equivalent corrosion resistance to Tin Plated finish

Both parts maintain Active product status, UL94 V-0 flammability rating, gold contact finish, and identical D-Sub 25-position shell geometry (Size 3, DB/B layout).

Frequently Asked Questions (FAQ)

Q: Can DBMV25PNK87 directly replace DSS3XPRAA15X in existing PCB designs?

A: Yes. Both connectors share identical 25-position D-Sub plug configuration, solder termination, board-side 4-40 flange mounting, and gold-plated copper alloy contacts. PCB footprints and mounting hole patterns are compatible.

Q: What is the difference between PBT Glass Filled and PCT dielectric materials?

A: PBT (Polybutylene Terephthalate) Glass Filled and PCT (Polycyclohexylenedimethylene Terephthalate) are distinct thermoplastic materials with different thermal and mechanical properties. Selection depends on specific application environmental requirements. Both materials are UL94 V-0 rated.

Q: Does the Board Lock feature on DSS3XPRAA15X affect substitution compatibility?

A: The Board Lock feature is a mechanical retention element on the DSS3XPRAA15X not present on DBMV25PNK87. If Board Lock functionality is required for the application, DBMV25PNK87 is not suitable. If mechanical retention is not specified, the absence of this feature does not prevent substitution.

Q: Are there compliance differences between ROHS3 and RoHS?

A: ROHS3 Compliant (DSS3XPRAA15X) indicates compliance with the most current RoHS 3 directive. RoHS Compliant (DBMV25PNK87) indicates compliance with RoHS standards. Both parts meet RoHS regulatory requirements; ROHS3 represents the newer standard revision.

Q: What does Moisture Sensitivity Level (MSL) 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. The DSS3XPRAA15X lists MSL as Not Applicable, indicating similar non-sensitive classification.

Q: Can DBMV25PNK87 be used in applications requiring the full operating temperature range?

A: DBMV25PNK87 is rated for -55°C ~ 125°C operation. DSS3XPRAA15X does not specify an operating temperature range. If the application requires operation within the -55°C ~ 125°C range, DBMV25PNK87 provides documented temperature performance. If the application requires temperatures outside this range, verification against DSS3XPRAA15X specifications is necessary.

Q: What is the significance of the 7.5A current rating on DBMV25PNK87?

A: The 7.5A current rating specifies the maximum continuous current per contact that DBMV25PNK87 can safely carry. DSS3XPRAA15X does not specify a current rating. If the application requires current-carrying capacity documentation, DBMV25PNK87 provides this specification.

Q: Are both parts available in equivalent quantities?

A: DSS3XPRAA15X has 748 units in current inventory. DBMV25PNK87 has 969 units in current inventory. Both parts are available in bulk packaging and Active product status.
