Key Parameters

Substitute Part Grouping Explanation

The substitute part 745132-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) is classified as an equivalent alternative based on the following critical parameters that determine substitution compatibility:

Matching Parameters:

• Connector style: D-Sub receptacle, female sockets
• Number of positions: 25
• Number of rows: 2
• Shell size, connector layout: 3 (DB, B)
• Mounting type: Through hole, right angle
• Termination method: Solder
• Contact finish: Gold (30.0µin / 0.76µm thickness)
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.69.4040

Differing Parameters:

• Current rating: 7.5A (main part) vs. 6A (substitute)
• Voltage rating: 1000V (main part) vs. 125V (substitute)
• Backset spacing: 0.406" / 10.30mm (main part) vs. 0.318" / 8.08mm (substitute)
• Operating temperature range: -55°C to 125°C (main part) vs. -55°C to 105°C (substitute)
• Flange feature: Mating side, female screwlock 4-40 (main part) vs. housing/shell unthreaded (substitute)
• Contact material: Copper alloy (main part) vs. phosphor bronze (substitute)
• RoHS status: RoHS compliant (main part) vs. not applicable (substitute)

Parameter Comparison

Engineering Selection Recommendations

Both the DBPV25S565GTLF and 745132-2 maintain active product status and share identical UL94 V-0 flammability certification and moisture sensitivity classification. Both parts are classified under the same ECCN and HTSUS codes, indicating regulatory equivalence for export and tariff purposes.

The DBPV25S565GTLF is RoHS compliant, while the 745132-2 status is listed as not applicable. The main part supports higher electrical specifications: 7.5A current rating versus 6A, and 1000V voltage rating versus 125V. The main part also accommodates a higher maximum operating temperature of 125°C compared to 105°C for the substitute.

Backset spacing differs between the two parts (0.406" versus 0.318"), which affects PCB layout and mechanical fit. The main part features a mating-side female screwlock (4-40), while the substitute uses an unthreaded housing/shell flange design.

Selection between these parts must be based on specific application requirements regarding electrical load, voltage environment, temperature exposure, and mechanical mounting constraints. The differing electrical ratings and physical dimensions require verification against circuit design specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Can 745132-2 be used as a direct replacement for DBPV25S565GTLF in all applications?

A: No. While both connectors share the same 25-position D-Sub configuration and basic form factor, they differ in critical electrical and mechanical parameters. The substitute part has lower current (6A vs. 7.5A) and voltage (125V vs. 1000V) ratings, a different backset spacing (0.318" vs. 0.406"), and different flange mounting features. Substitution is only valid for applications where the lower electrical specifications and different mechanical dimensions are acceptable.

Q: What is the significance of the backset spacing difference?

A: Backset spacing determines the distance from the connector mounting surface to the contact plane. The 0.088" difference (0.406" vs. 0.318") affects PCB layout, component clearance, and mechanical assembly. Connectors with different backset spacing are not interchangeable on the same PCB without redesign.

Q: Are both parts suitable for high-voltage applications?

A: The DBPV25S565GTLF is rated for 1000V, making it suitable for high-voltage applications. The 745132-2 is rated for 125V only and is not appropriate for high-voltage environments. Application voltage requirements must be verified before selecting either part.

Q: What is the difference between the flange features?

A: The DBPV25S565GTLF features a mating-side female screwlock (4-40), which provides threaded fastening for secure mechanical connection. The 745132-2 uses an unthreaded housing/shell flange, which may require different mounting hardware or techniques. The mounting method must be compatible with the application's mechanical design.

Q: Do both parts meet the same compliance standards?

A: Both parts are classified as UL94 V-0 for material flammability and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The DBPV25S565GTLF is RoHS compliant; the 745132-2 status is not applicable. Compliance requirements for your specific application must be verified.

Q: What is the maximum operating temperature for each part?

A: The DBPV25S565GTLF operates from -55°C to 125°C. The 745132-2 operates from -55°C to 105°C. Applications requiring operation above 105°C require the main part.

Q: Are the contact materials interchangeable?

A: The DBPV25S565GTLF uses copper alloy contacts, while the 745132-2 uses phosphor bronze contacts. Both are plated with gold to 30.0µin thickness. Contact material differences may affect electrical performance characteristics and corrosion resistance in specific environments.
