Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub 25-position receptacles is based on the following critical parameters that must remain constant:

Core Electrical Parameters (Non-negotiable):

• Connector type: Receptacle, Female Sockets
• Number of positions: 25
• Number of rows: 2
• Shell size/layout: 3 (DB, B)
• Mounting type: Through Hole
• Termination method: Solder

Acceptable Variation Parameters:

• Flange feature design (board-side mounting options include 4-40 threads, M3 threads, unthreaded housings, or mating-side configurations)
• Manufacturer (Amphenol ICC, TE Connectivity)
• Product series (D, AMPLIMITE HDP-20, Delta D)
• Shell material finish variants (Tin Plated, Tin-Nickel Plated)
• Contact material (Brass, Phosphor Bronze, Copper Alloy)
• Dielectric material composition (Thermoplastic, Glass-Filled Polyester, Polybutylene Terephthalate)
• Packaging format (Bulk, Tray)

Conditional Parameters (Application-dependent):

• Current rating may vary by contact material and design (5A to 7.5A per contact)
• Contact finish thickness specifications
• Operating temperature range (all listed substitutes operate within -55°C to 125°C)

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence: Parts D25S24A4GX00LF, D25S24A6GX00LF, and 6-338315-2 maintain the closest electrical performance profile with matching shell size, 25-position layout, and through-hole solder termination. These parts carry full RoHS compliance and active product status.

For Higher Current Capacity: L77DBH25SOL2 provides the highest current rating at 7.5A per contact. Substitute parts D25S24 series and 2-338315-2 operate at 5A to 6A per contact, making them suitable only for applications not exceeding these current levels.

For Temperature-Critical Applications: L77DBH25SOL2 maintains the full operating range of -55°C to 125°C. The TE Connectivity AMPLIMITE HDP-20 series (2-338315-2) operates to -55°C to 105°C, limiting its use in applications requiring higher temperature operation above 105°C.

For Packaging and Inventory Considerations: Delta D series parts (D25S24 variants) show the highest inventory levels across multiple flange configurations, ranging from 1102 to 1831 units. TE Connectivity parts offer alternative sourcing with the 6-338315-2 providing 1779 units in tray packaging.

Compliance Considerations: All listed substitutes carry RoHS certification. The L77DBH25SOL2, D25S24 series, and DB25S364TLF show REACH Unaffected status, while 2-338315-2 and D25S24B4PA00LF show REACH Affected or vendor-undefined status. Applications subject to REACH restrictions must use REACH Unaffected parts.

Frequently Asked Questions (FAQ)

Q: Can I use a TE Connectivity part as a direct drop-in replacement for the Amphenol ICC L77DBH25SOL2?

A: Yes, with board layout modifications. The 6-338315-2 and 2-338315-2 match the 25-position DB-3 shell specification and solder termination method. However, the M3 flange feature on 2-338315-2 differs from the 4-40 board-side mount on L77DBH25SOL2, requiring PCB redesign. The 6-338315-2 uses 4-40 threading, matching the original mounting requirement.

Q: What is the current rating difference between L77DBH25SOL2 (7.5A) and the Delta D series (5A)?

A: The L77DBH25SOL2 uses brass contacts with a higher current capacity specification. Delta D series connectors employ phosphor bronze contacts rated at 5A per contact. Applications exceeding 5A per signal line must use the original L77DBH25SOL2 or verify that current distribution across the 25 positions does not exceed the lower rating.

Q: Are there packaging differences I should know about?

A: Yes. L77DBH25SOL2 is supplied in tray packaging with 752 units. TE Connectivity 2-338315-2 is supplied in bulk packaging, while 6-338315-2 uses tray packaging. Delta D series parts are available in tray quantities ranging from 1102 to 1831 units. Verify your procurement workflow accepts the offered packaging format.

Q: Which substitute parts are suitable for -55°C to 125°C full temperature range applications?

A: L77DBH25SOL2, all Delta D series parts (D25S24A4GL00LF, D25S24A4GX00LF, D25S24A4PL00LF, D25S24A6GX00LF, D25S24B4GV00LF, D25S24B4PA00LF), and DB25S364TLF support the full -55°C to 125°C operating range. The TE Connectivity AMPLIMITE HDP-20 series (2-338315-2 and 6-338315-2) is limited to -55°C to 105°C.

Q: What is the significance of flange feature differences between 4-40, M3, and unthreaded designs?

A: Flange features determine PCB mounting and mechanical retention. 4-40 indicates standard inch-thread board mounts common in North American designs. M3 specifies metric-thread mounts used in international applications. Unthreaded housings rely on friction fit or adhesive retention. The specific choice depends on board design; switching between these requires PCB modification.

Q: Do all substitute parts maintain gold plating on contacts?

A: Yes. All listed substitutes feature gold contact finish. Contact finish thickness varies; L77DBH25SOL2 specifies 8.00µin (0.203µm), while Delta D series parts specify flash plating or 30.0µin (0.76µm) thickness on D25S24A6GX00LF. These thickness differences do not affect electrical compatibility in standard solder termination applications.

Q: What compliance certifications should I verify for my application?

A: All parts carry UL94 V-0 flammability rating and MSL Level 1 (Unlimited moisture sensitivity). RoHS compliance is universal. For REACH-regulated designs, use parts marked REACH Unaffected (L77DBH25SOL2, D25S24 series, DB25S364TLF) rather than REACH Affected variants.
