DB51213 D-Sub 25 Position Backshell Connector Equivalent & Substitute Parts

Part Overview

The DB51213 is a 25 position one-piece backshell connector manufactured by ITT Cannon, LLC, designed for D-Sub applications requiring 90° cable exit configuration. This unshielded thermoplastic backshell is classified as an active product and is RoHS compliant. Substitute parts are identified when inventory constraints, lead time requirements, or specific application needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility within the D-Sub connector ecosystem.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB51213 is determined by strict alignment of the following critical parameters:

• Position Count: Must be 25 positions
• Compatible Shell Size: Must be Shell Size B
• Compatible D-Sub Size: Must support 25pos and HD44pos configurations
• Shielding Type: Must be unshielded
• Primary Material: Must be thermoplastic plastic
• Color: Must be black
• Cable Exit Configuration: Must support 90° exit (additional cable exit angles do not disqualify a substitute)

The substitute part 207345-1 meets all mandatory substitution criteria. While it offers additional 180° cable exit capability and employs a hinged backshell design (versus one-piece), these differences represent functional enhancements rather than incompatibilities. Both parts are active products with current RoHS compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both DB51213 and 207345-1 are active products with current RoHS compliance certifications suitable for D-Sub 25 position backshell applications. Selection between these parts should be based on:

DB51213 (ITT Cannon, LLC): One-piece backshell design with fixed 90° cable exit. Appropriate for applications where cable routing is predetermined and one-piece construction is preferred.

207345-1 (TE Connectivity AMP Connectors): Hinged backshell design with dual cable exit capability (90° and 180°). Appropriate for applications requiring flexible cable exit angle configuration or where hinged assembly provides installation advantages. ROHS3 compliance provides alignment with current regulatory standards.

Both parts maintain identical electrical and mechanical compatibility within the D-Sub 25 position connector family, supporting Shell Size B and both 25pos and HD44pos D-Sub configurations.

Frequently Asked Questions (FAQ)

Q: Can 207345-1 be used as a direct replacement for DB51213?

A: Yes. Both parts are 25 position unshielded thermoplastic backshells with Shell Size B compatibility and support for 25pos and HD44pos D-Sub configurations. The hinged design and dual cable exit angles of 207345-1 represent functional enhancements that do not compromise compatibility.

Q: What is the difference between one-piece and hinged backshell designs?

A: One-piece backshells (DB51213) are molded as a single unit with fixed cable exit angles. Hinged backshells (207345-1) feature a movable hinge allowing adjustment of cable exit angle during assembly. Both designs achieve the same electrical and mechanical interface with D-Sub connectors.

Q: Are there compatibility differences between Shell Size B and other shell sizes?

A: Yes. Shell Size B is specific to 25 position and HD44 position D-Sub connectors. Parts specified for other shell sizes (A, C, D, E) are not compatible with DB51213 applications.

Q: Does the additional 180° cable exit option on 207345-1 affect its use in 90° applications?

A: No. The 207345-1 supports both 90° and 180° cable exit configurations. Applications requiring only 90° exit can utilize this part without modification.

Q: What packaging considerations apply to these parts?

A: DB51213 packaging is not specified in available documentation. 207345-1 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications before ordering.

Q: Are both parts RoHS compliant?

A: Yes. DB51213 is RoHS compliant. 207345-1 is ROHS3 compliant, representing current regulatory alignment.
