Engineering Selection Recommendations
Direct Equivalent Selection: The TE Connectivity 5646373-1 is the recommended primary substitute for the obsolete 646373-1. This part maintains identical electrical and mechanical specifications, operates at the same voltage and current ratings, and supports the full operating temperature range. The 5646373-1 is currently in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment.
Amphenol ICC (FCI) Millipacs® Series Selection: The HM2P88PA8110AALF, HM2P88PC8110N9LF, and HM2P88PD8110N9LF connectors provide functionally equivalent substitution with identical 200-position, 2.00mm pitch, 8-row through-hole press-fit configuration. All three parts maintain 1.5A current rating and 750Vrms voltage rating across the -55°C to 125°C operating temperature range. These connectors are in active production with RoHS compliance. The HM2P88PD8110N9LF variant includes a board guide feature. All three parts are available in tray packaging.
Molex VHDM 74060 Series Consideration: The Molex VHDM 74060 series (0740602502, 0740602504, 0740602506, 0740602509, 0740608502) provides alternative substitution with enhanced current rating (3A) and shielded design. However, these connectors operate at reduced voltage (120V) and reduced maximum operating temperature (105°C). Selection of Molex alternatives requires verification that application requirements do not exceed 120V operation and 105°C maximum temperature. The 0740602504 and 0740608502 variants provide ROHS3 compliance. Packaging options include tube and bulk formats.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 5646373-1 be used as a direct replacement for the 646373-1?
A: Yes. The 5646373-1 is a direct equivalent with identical electrical and mechanical specifications. Both connectors feature 200 positions, 0.079" (2.00mm) pitch, 8-row configuration, through-hole press-fit termination, 1.5A current rating, and 750Vrms voltage rating across -55°C to 125°C operating temperature. The primary difference is product status (active versus obsolete) and packaging format (tube).
Q: What are the key differences between TE Connectivity and Amphenol ICC (FCI) substitutes?
A: Both manufacturers provide 200-position, 2.00mm pitch, 8-row through-hole press-fit connectors with identical electrical ratings (1.5A, 750Vrms, -55°C to 125°C). The primary distinction is connector series designation (Z-PACK versus Millipacs®) and packaging format (TE Connectivity in tube; Amphenol ICC in tray). All parts maintain gold contact finish and equivalent current/voltage performance.
Q: Are Molex VHDM 74060 connectors suitable substitutes?
A: Molex VHDM 74060 connectors provide mechanical compatibility (200 positions, 2.00mm pitch, 8-row through-hole press-fit) but operate at reduced voltage (120V versus 750Vrms) and reduced maximum temperature (105°C versus 125°C). Selection requires application-level verification that voltage and temperature requirements do not exceed Molex specifications. Molex connectors provide enhanced current rating (3A) and shielded design.
Q: What packaging formats are available for substitute parts?
A: TE Connectivity 5646373-1 is supplied in tube packaging. Amphenol ICC (FCI) Millipacs® series connectors are supplied in tray packaging. Molex VHDM 74060 series connectors are available in both tube and bulk packaging formats (0740602502, 0740602504, 0740602506 in tube; 0740602509, 0740608502 in bulk).
Q: Do all substitute parts meet RoHS compliance requirements?
A: TE Connectivity 5646373-1 and all Amphenol ICC (FCI) Millipacs® variants meet RoHS compliance (ROHS3 or RoHS Compliant). Molex VHDM 74060 series compliance varies: 0740602504 and 0740608502 are ROHS3 compliant; 0740602502 and 0740602509 are RoHS non-compliant. Regulatory requirements must be verified for specific applications.
Q: What is the significance of contact finish thickness variation?
A: Contact finish thickness is specified at 30.0µin (0.76µm) for the main part and most substitutes. Molex variants 0740602506 and 0740602509 feature increased thickness at 50.0µin (1.27µm). Both thicknesses provide gold plating for corrosion resistance and electrical performance. Thickness variation does not affect electrical compatibility but may influence connector durability in high-cycle mating applications.
Q: Are there position count variations among substitute parts?
A: The main part and all direct substitutes maintain 200 positions. One Amphenol ICC (FCI) variant, HM2P88PA8111AALF, features 250 positions (200 + 50 ground) with 8 + 2 row configuration and is not recommended as a direct substitute due to position count difference.
