Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 5788797-1 be used as a direct replacement for 788797-1?
A: Yes. The 5788797-1 is electrically and mechanically identical to 788797-1, with the primary difference being ROHS3 compliance status. Both parts share the same AMPLIMITE HD-20 series designation, 9-position configuration, 6A current rating, 125V voltage rating, and 0.318" backset spacing. The 5788797-1 is suitable for direct substitution in all applications where the 788797-1 was originally specified.
Q: What are the key differences between TE Connectivity and Amphenol ICC substitute parts?
A: TE Connectivity 747844-6 maintains the AMPLIMITE HD-20 series and 6A current rating. Amphenol ICC Delta D series parts (D09S33E4GL00LF, D09S33E4GV00LF, D09S33E4GX00LF) offer 300V voltage rating and -55°C to 125°C operating temperature range, but feature 5A per contact current rating. Amphenol ICC parts are available with ROHS3 compliance. Flange feature configurations differ between manufacturers.
Q: Are NorComp Inc. parts suitable substitutes for the 788797-1?
A: NorComp Inc. parts provide functional equivalence with specific parameter variations. The 174-E series features 0.370" backset spacing and -50°C to 100°C operating temperature, which differ from the primary part. The 182 series maintains 0.318" backset spacing and -55°C to 105°C operating temperature, matching the primary part's geometry and thermal range. Current rating for all NorComp parts is 5A, which is lower than the primary part's 6A rating. NorComp parts are suitable when these parameter variations are acceptable for the application.
Q: What is the significance of backset spacing in connector substitution?
A: Backset spacing defines the distance from the connector mounting surface to the contact plane. The primary part 788797-1 specifies 0.318" (8.08mm) backset spacing. NorComp 174-E series parts feature 0.370" (9.40mm) spacing, which is not interchangeable without PCB redesign. NorComp 182 series and Amphenol ICC Delta D series maintain 0.318" spacing, ensuring mechanical compatibility with existing PCB layouts.
Q: How does current rating affect part selection?
A: The primary part 788797-1 is rated for 6A continuous current. Substitute parts from NorComp Inc. and Amphenol ICC are rated for 5A per contact. In applications where current density approaches or exceeds 5A per contact, the primary part or TE Connectivity 5788797-1 and 747844-6 are required. For applications operating below 5A per contact, lower-rated substitutes are functionally adequate.
Q: What compliance certifications should be considered for new designs?
A: The primary part 788797-1 is RoHS non-compliant. For new designs subject to RoHS regulations, the TE Connectivity 5788797-1 (ROHS3 compliant), Amphenol ICC Delta D series (ROHS3 compliant), and NorComp Inc. 174-E and 182 series (ROHS3 compliant) are appropriate selections. Compliance status is provided in the parameter comparison table.
Q: Can parts with different flange features be interchanged?
A: Flange features determine the mechanical interface and mounting method. The primary part 788797-1 features mating side female screwlock (4-40). Substitute parts offer variations including housing/shell unthreaded, housing/shell (4-40), housing/shell (M3), and mating side female screwlock (4-40). Parts with different flange features require different mounting hardware and may not be directly interchangeable without mechanical redesign.
Q: What is the impact of shell material and finish on connector performance?
A: The primary part features steel tin-plated shell. Substitute parts offer steel tin-nickel plated or steel nickel-plated finishes. Shell material and finish affect corrosion resistance, contact resistance, and environmental performance. Tin-plated shells provide lower contact resistance, while nickel-plated shells offer enhanced corrosion resistance in harsh environments. Selection depends on application environmental requirements.
Q: Are there inventory considerations when selecting substitute parts?
A: Yes. Inventory levels vary significantly among substitute parts. The primary part 788797-1 has 929 units in stock. The TE Connectivity 5788797-1 has 2290 units available. NorComp 182-009-213R531 has the highest inventory at 7246 units. Amphenol ICC D09S33E4GV00LF has 6905 units. Inventory availability may influence part selection for high-volume production requirements.
