DB25S565MT Equivalent & Substitute Parts

Part Overview

The DB25S565MT is a 25 Position D-Sub Receptacle connector with female sockets, manufactured by Amphenol ICC (FCI). This connector is designed for right-angle, through-hole solder termination applications. The part is currently in active production status with 847 pieces available in new original inventory. D-Sub connectors of this configuration are essential for legacy and industrial applications requiring standardized 25-position signal distribution. Substitute parts are identified when electrical and mechanical parameters remain within the allowed specifications for this connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DB25S565MT are identified based on strict equivalence of the following critical parameters:

• Connector type classification (D-Sub Receptacle, Female Sockets)
• Position count and row configuration (25 positions, 2 rows)
• Shell size designation (3 / DB, B)
• Mounting orientation and method (Through Hole, Right Angle)
• Termination technology (Solder)
• Electrical ratings (5A per contact, 300V)
• Operating temperature range (-55°C to 125°C)
• Material and finish specifications (Steel shell with tin plating; Phosphor Bronze contacts with gold finish)
• Compliance certifications (RoHS Compliant)

The DB25S565MTLF meets all these criteria and is therefore classified as a direct substitute. The primary distinction is packaging format (Tray for the substitute versus unspecified for the main part) and the inclusion of mounting brackets as a standard feature on the substitute variant.

Parameter Comparison

Engineering Selection Recommendations

Both the DB25S565MT and DB25S565MTLF are manufactured by Amphenol ICC (FCI) and share identical electrical and mechanical specifications for the core connector function. The DB25S565MTLF is documented with explicit RoHS Compliance certification and includes integrated mounting brackets as a standard feature. Selection between these parts should be based on:

• Packaging requirements: The DB25S565MTLF is supplied in Tray packaging, which may be preferred for automated assembly or bulk handling operations.
• Mounting bracket necessity: The DB25S565MTLF includes mounting brackets as a standard feature, eliminating the need for separate bracket procurement if mechanical mounting is required.
• Compliance documentation: The DB25S565MTLF provides explicit RoHS Compliance status, which may be required for specific regulatory or customer qualification requirements.
• Inventory availability: Both parts maintain adequate stock levels (847 and 868 pieces respectively) for production planning.

Frequently Asked Questions (FAQ)

Q: Can DB25S565MTLF be used as a direct replacement for DB25S565MT?

A: Yes. Both connectors are electrically and mechanically equivalent. They share identical position count (25), shell size (3/DB), mounting type (through-hole right angle), termination method (solder), current rating (5A per contact), voltage rating (300V), and operating temperature range (-55°C to 125°C). The primary differences are packaging format and the inclusion of mounting brackets on the MTLF variant.

Q: What is the significance of the mounting brackets on the DB25S565MTLF?

A: The mounting brackets are integrated mechanical features that facilitate panel or chassis mounting. If your application requires mechanical mounting support, the DB25S565MTLF eliminates the need to source and install separate bracket components.

Q: Are there any electrical performance differences between these two parts?

A: No. Both connectors maintain identical electrical specifications: 5A per contact current rating, 300V voltage rating, phosphor bronze contacts with gold finish, and -55°C to 125°C operating temperature range.

Q: What does the packaging difference mean for my procurement?

A: The DB25S565MTLF is supplied in Tray packaging, which is optimized for automated assembly equipment and bulk handling. If your manufacturing process uses automated pick-and-place systems, Tray packaging may provide operational advantages. The DB25S565MT packaging format is not specified in available documentation.

Q: Is RoHS Compliance a factor in selecting between these parts?

A: The DB25S565MTLF is explicitly documented as RoHS Compliant. If your application or customer requirements mandate RoHS Compliance certification, the DB25S565MTLF provides documented compliance status. The DB25S565MT compliance status is not specified in available documentation.

Q: Can I use these connectors in high-temperature applications?

A: Both connectors are rated for operating temperatures from -55°C to 125°C. This range is suitable for industrial and commercial applications but may not be adequate for specialized high-temperature environments requiring extended temperature ranges.
