Substitute Part Grouping Explanation
Substitution of the obsolete 788800-2 is determined by strict equivalence across the following critical parameters: connector style (D-Sub), connector type (receptacle with female sockets), number of positions (25), number of rows (2), shell size and layout (3/DB, B), mounting type (through-hole, right-angle), termination method (solder), and backset spacing (0.318"/8.08mm). These parameters ensure mechanical and electrical compatibility with mating D-Sub plugs and existing printed circuit board layouts.
Secondary parameters including shell material finish, contact finish, current rating, voltage rating, operating temperature range, and dielectric material are evaluated to determine functional equivalence. Parts meeting all critical parameters are classified as direct substitutes. Parts with variations in secondary parameters are classified as similar substitutes, with specific parameter differences noted for engineering evaluation.
The substitute parts identified fall into two categories:
Direct Substitute (Active Status): 5788800-2 from TE Connectivity AMP Connectors, which maintains identical specifications to the main part with the exception of RoHS compliance status (RoHS Compliant versus RoHS non-compliant).
Similar Substitutes (Active Status): Parts from NorComp Inc. (182 series), Mercury United Electronics, Inc. (622 series), and Amphenol ICC/FCI (Delta D series) that maintain all critical mechanical and electrical parameters while introducing variations in secondary specifications such as shell material finish, current rating, voltage rating, operating temperature range, and dielectric material composition.

Frequently Asked Questions (FAQ)
Q: Can the 5788800-2 be used as a direct replacement for the 788800-2 in existing designs?
A: Yes. The 5788800-2 maintains identical electrical and mechanical specifications to the 788800-2, including 25-position configuration, 2-row layout, shell size 3 (DB, B), through-hole right-angle mounting, solder termination, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The primary difference is RoHS compliance status. The 5788800-2 is currently active with 5,684 units in stock.
Q: What are the key differences between the TE Connectivity 5788800-2 and the Amphenol ICC D25S33E4GV00LF?
A: Both parts maintain identical mechanical compatibility with 25-position, 2-row, shell size 3 (DB, B) configuration and through-hole right-angle solder termination. The D25S33E4GV00LF features higher voltage rating (300V versus 125V), extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), and lower current rating (5A per contact versus 6A). The D25S33E4GV00LF uses polybutylene terephthalate (PBT) dielectric material versus polyamide (PA) in the 5788800-2. Both are RoHS compliant.
Q: Are the NorComp 182 series parts compatible with the same mating connectors as the 788800-2?
A: Yes. The NorComp 182-025-213R171 and 182-025-213R531 maintain identical shell size 3 (DB, B) configuration, 25-position, 2-row layout, and backset spacing (0.318"/8.08mm) as the 788800-2. These parts are mechanically compatible with standard D-Sub 25-position plugs. The NorComp parts offer additional panel mount capability in addition to through-hole mounting.
Q: What is the significance of the contact finish thickness specification in the D25S33E6GV00LF?
A: The D25S33E6GV00LF specifies contact finish thickness of 30.0µin (0.76µm), whereas the main part 788800-2 specifies flash thickness. Flash thickness is a thin, unspecified gold plating applied for corrosion protection. The 30.0µin specification provides a defined minimum gold thickness for enhanced durability and contact reliability in high-cycle mating applications.
Q: Why does the Mercury United Electronics 622-025-260-043 have a lower current rating than the main part?
A: The 622-025-260-043 specifies 3A per contact current rating versus 6A for the main part 788800-2. This difference reflects design variations in contact geometry, material composition, and thermal characteristics. The 622-025-260-043 is suitable for applications with lower current requirements. Applications requiring 6A current capacity should utilize the 5788800-2, D25S33E4GV00LF, or D25S33E4GX00LF.
Q: What mounting type variations exist among the substitute parts?
A: The main part 788800-2 and most substitutes feature through-hole, right-angle mounting. The NorComp 182 series (182-025-213R171 and 182-025-213R531) offer panel mount capability in addition to through-hole mounting. The Mercury United Electronics 622-025-260-043 features board edge mounting in addition to through-hole mounting. Selection of mounting type depends on specific printed circuit board layout requirements.
Q: Are all substitute parts RoHS compliant?
A: The 5788800-2, D25S33E4GV00LF, D25S33E4GX00LF, D25S33E6GV00LF from TE Connectivity and Amphenol ICC are RoHS Compliant. The NorComp 182-025-213R171 and 182-025-213R531 are ROHS3 Compliant. The Mercury United Electronics 622-025-260-043 is ROHS3 Compliant. The main part 788800-2 is RoHS non-compliant. For applications requiring RoHS compliance, all identified substitutes are suitable.
Q: What dielectric material variations exist among the substitute parts?
A: The main part 788800-2 uses polyamide (PA), nylon dielectric material. The NorComp 182 series uses polyamide (PA9T), nylon 9T. The Mercury United Electronics 622-025-260-043 uses polyester thermoplastic. The Amphenol ICC Delta D series (D25S33E4GV00LF, D25S33E4GX00LF, D25S33E6GV00LF) use polybutylene terephthalate (PBT). These material variations provide different thermal and mechanical properties suitable for different application environments.
Q: What is the operating temperature range difference between the main part and the Amphenol ICC substitutes?
A: The main part 788800-2 operates from -55°C to 105°C. The Amphenol ICC Delta D series (D25S33E4GV00LF, D25S33E4GX00LF, D25S33E6GV00LF) operate from -55°C to 125°C, providing an extended upper temperature limit of 20°C. This extended range is suitable for applications in higher-temperature environments. The Mercury United Electronics 622-025-260-043 operates from -55°C to 85°C, providing a reduced upper temperature limit.
