DBM25SA208 Equivalent & Substitute Parts Reference

Part Overview

The DBM25SA208 is a 25-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount applications with female socket contacts. This connector is actively produced and maintains a stock inventory of 658 pieces. The part features solder cup termination, steel shell with yellow chromate plated zinc finish, and gold-plated contacts rated for 7.5A operation across a temperature range of -55°C to 125°C.

Identifying equivalent and substitute parts becomes necessary when panel mount configurations require alternative mounting approaches, when supply chain considerations necessitate sourcing from different manufacturers, or when specific compliance requirements must be met for new applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBM25SA208 is determined by the following core parameters that must remain constant across all equivalent parts:

• 25-position D-Sub receptacle configuration with female socket contacts
• Shell size 3 (DB, B) layout maintaining mechanical compatibility
• 2-row contact arrangement
• Signal contact type
• 7.5A current rating capability
• Operating temperature range of -55°C to 125°C
• Copper alloy contact material with machined contact form
• UL94 V-0 flammability rating

The substitute parts identified (164A16589X and 164A16689X) maintain these core electrical and mechanical parameters. The primary differences between the main part and substitutes involve mounting methodology (panel mount versus through-hole), termination approach (solder cup versus solder), shell material finish (yellow chromate plated zinc versus tin plated), and regulatory compliance status (RoHS non-compliant versus ROHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

The DBM25SA208 and its identified substitutes (164A16589X and 164A16689X) are all active products from established manufacturers with equivalent electrical performance characteristics. Selection between these parts depends on application-specific requirements:

For applications requiring panel mount configuration with solder cup termination and yellow chromate plated zinc shell finish, the DBM25SA208 remains the specified choice. This part is RoHS non-compliant and suitable for legacy systems or applications where RoHS compliance is not mandated.

For applications transitioning to through-hole PCB mounting with solder termination, the 164A16589X and 164A16689X from Amphenol CONEC provide ROHS3-compliant alternatives. Both parts feature tin-plated steel shells, board lock features, and IP20 ingress protection. The 164A16589X includes board-side flange mounting (4-40), while the 164A16689X features mating-side flange mounting (4-40).

Applications subject to RoHS3 compliance requirements should utilize either 164A16589X or 164A16689X. Applications requiring panel mount configuration must retain the DBM25SA208 or source equivalent panel mount alternatives from other manufacturers.

Frequently Asked Questions (FAQ)

Q: Can 164A16589X or 164A16689X be used as direct replacements for DBM25SA208 in existing panel mount applications?

A: No. The DBM25SA208 is designed for panel mount installation with solder cup termination. The 164A16589X and 164A16689X are through-hole connectors with solder termination and board-side or mating-side flange mounting. These require different PCB layout and mounting hole configurations. Direct substitution would require redesign of the mounting interface.

Q: What is the difference between 164A16589X and 164A16689X?

A: Both parts are 25-position D-Sub receptacles from Amphenol CONEC with identical electrical specifications. The primary difference is flange location: 164A16589X features board-side flange mounting (4-40), while 164A16689X features mating-side flange mounting (4-40). Contact finish thickness also differs, with 164A16589X specified at 8.00µin (0.203µm) and 164A16689X specified as flash.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 164A16589X and 164A16689X are ROHS3 compliant. The DBM25SA208 is RoHS non-compliant. For applications requiring RoHS3 compliance, substitutes must be selected from the Amphenol CONEC alternatives.

Q: Do the substitute parts maintain the same current rating and temperature range?

A: Yes. All three parts (DBM25SA208, 164A16589X, and 164A16689X) are rated for 7.5A current and operate across the -55°C to 125°C temperature range. Electrical performance characteristics remain equivalent across all options.

Q: What packaging is available for each part?

A: The DBM25SA208 packaging is not specified in available documentation. The 164A16589X and 164A16689X are supplied in tray packaging. Confirm packaging requirements with your procurement department before finalizing part selection.
