DBM25SP D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DBM25SP is a 25-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through-hole, right-angle solder termination applications. This connector features female sockets with a DB/B shell size (Size 3) and is rated for 7.5A continuous current operation across an operating temperature range of -55°C to 125°C. The part maintains active product status with 911 units currently in stock.

Alternative equivalent parts may be required due to supply chain considerations, specific compliance requirements, or application-specific performance parameters. Substitute parts must maintain compatibility across critical electrical and mechanical specifications including connector style, position count, mounting configuration, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBM25SP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Termination: Solder
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 7.5A requirement
• Operating Temperature: Substitute must support minimum -55°C to 125°C range
• Contact Finish: Gold plating acceptable; alternative finishes require application verification
• Shell Material/Finish: Steel construction with alternative plating acceptable
• Dielectric Material: Alternative materials acceptable if UL94 V-0 compliance maintained

The substitute part 1-106507-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) meets all mandatory matching parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

DBM25SP (ITT Cannon, LLC) remains the primary specification when:

• Operating temperature range of -55°C to 125°C is required
• Current load approaches or exceeds 6A
• Yellow chromate plating is specified for corrosion resistance in specific environments
• RoHS non-compliance is acceptable for the application
• Copper alloy contact material is required

1-106507-2 (TE Connectivity AMP Connectors) qualifies as a functional substitute when:

• Operating temperature maximum of 105°C is acceptable
• Current requirements do not exceed 6A continuous
• ROHS3 compliance is required or preferred
• Tin plating and phosphor bronze contacts are compatible with application requirements
• Board lock feature provides additional mechanical retention benefit
• Tray packaging meets procurement specifications

Both parts maintain UL94 V-0 flammability compliance and identical mechanical form factor (25-position, 2-row, DB/B shell, right-angle solder mount). Selection between these parts depends on specific application thermal, electrical, and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can 1-106507-2 replace DBM25SP in all applications?

A: No. The substitute part has two critical limitations: maximum operating temperature of 105°C (versus 125°C for DBM25SP) and current rating of 6A (versus 7.5A). Substitution is valid only when application requirements fall within these lower specifications.

Q: What is the difference between yellow chromate and tin plating on the shell?

A: Both are corrosion-resistant finishes on steel shells. Yellow chromate plating (DBM25SP) provides enhanced corrosion resistance in harsh environments. Tin plating (1-106507-2) offers adequate protection for standard industrial applications. Selection depends on environmental exposure requirements.

Q: Are the contact materials interchangeable?

A: Both copper alloy (DBM25SP) and phosphor bronze (1-106507-2) are acceptable contact materials for D-Sub connectors. Phosphor bronze offers slightly improved spring characteristics. Both materials are compatible with gold plating and standard signal applications.

Q: What does the Board Lock feature on 1-106507-2 provide?

A: Board lock is a mechanical retention feature that prevents accidental connector separation from the PCB during handling or vibration. This is an additional benefit not present on the DBM25SP.

Q: Does RoHS compliance affect electrical performance?

A: No. ROHS3 compliance (1-106507-2) versus non-compliance (DBM25SP) does not impact electrical performance. Compliance status is a regulatory and procurement consideration, not a functional specification.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes, from a mechanical and electrical interface perspective. Both parts have identical 25-position, 2-row DB/B shell configuration and right-angle solder termination. However, thermal and current design margins must be verified against application requirements before substitution.

Q: What is the significance of the 0.406" backset spacing on 1-106507-2?

A: Backset spacing defines the distance from the connector mounting face to the solder contact plane. This specification is provided for 1-106507-2 but not for DBM25SP in the available data. Both connectors use standard D-Sub right-angle geometry and are mechanically compatible.
