Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBP25S464TLF is determined by strict alignment of core electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: D-Sub receptacle with female sockets
• Position count: 25 positions in 2-row configuration
• Shell size: 3 (DB, B) layout
• Termination: Wire wrap capability
• Current rating: Minimum 7.5A per contact
• Voltage rating: Minimum 300V
• Temperature range: -55°C to 125°C coverage
• Contact finish: Gold plating for signal integrity

The DBP25S465TLF qualifies as a direct substitute based on matching all critical parameters while offering enhanced specifications in voltage rating and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DBP25S465TLF is the qualified substitute for the obsolete DBP25S464TLF based on the following engineering criteria:

Electrical Compatibility: Both connectors maintain identical current rating (7.5A per contact) and operating temperature range (-55°C to 125°C). The DBP25S465TLF provides enhanced voltage rating (1000V versus 300V), ensuring compatibility with the original 300V specification while offering margin for higher-voltage applications.

Mechanical Compatibility: Both connectors share identical 25-position, 2-row D-Sub configuration with shell size 3 (DB, B) and wire wrap termination. The DBP25S465TLF adds panel mount capability as a supplementary feature without compromising through-hole mounting compatibility.

Compliance & Supply Status: The DBP25S465TLF is active in production with ROHS3 compliance and REACH compliance documentation, addressing regulatory requirements for modern applications. The original DBP25S464TLF is obsolete with no ongoing manufacturing support.

Material Specifications: Contact finish specifications are enhanced in the substitute (Gold, GXT™ with 30.0µin thickness versus unspecified gold plating), providing documented contact durability and signal integrity assurance.

Frequently Asked Questions (FAQ)

Q: Can the DBP25S465TLF directly replace the DBP25S464TLF in existing designs?

A: Yes. Both connectors share identical electrical ratings (7.5A, -55°C to 125°C operation), mechanical configuration (25-position, 2-row, shell size 3), and termination method (wire wrap). The substitute meets or exceeds all original specifications.

Q: What is the difference in mounting between these two connectors?

A: The DBP25S464TLF is through-hole mount only. The DBP25S465TLF supports both panel mount and through-hole mounting, providing design flexibility without compromising original through-hole applications.

Q: Why does the DBP25S465TLF have a higher voltage rating (1000V vs 300V)?

A: The higher voltage rating represents an enhanced specification in the active substitute part. This does not affect compatibility with 300V applications and provides additional safety margin for designs operating at lower voltages.

Q: Are there packaging differences between these parts?

A: The DBP25S464TLF packaging is not specified. The DBP25S465TLF is supplied in Tray packaging. Verify packaging requirements for your assembly process.

Q: What compliance certifications apply to the substitute part?

A: The DBP25S465TLF is ROHS3 compliant and REACH affected. These certifications ensure compliance with current environmental and hazardous substance regulations for new designs and legacy system updates.

Q: Is the dielectric material change from Polyester to Thermoplastic significant?

A: Both materials support the identical operating temperature range (-55°C to 125°C) and moisture sensitivity level (MSL 1). The thermoplastic material in the substitute provides equivalent electrical insulation performance for this connector category.
