Engineering Selection Recommendations
Primary Substitute (Direct Equivalent):
The TE Connectivity 2301826-1 is the direct equivalent from the same manufacturer and series (AMPLIMITE HD-20). This part maintains identical connector geometry, shell size, position count, and termination method. The 2301826-1 is currently in active production status with 2400 units in stock. The primary difference is a reduced current rating (1.5A versus 3A), which represents a derating and requires circuit-level evaluation. The 2301826-1 is ROHS3 compliant, addressing regulatory requirements that the obsolete 1-1634218-2 does not meet.
Secondary Substitutes (Mercury United Electronics 627 Series):
The Mercury United Electronics 627-009-220-042, 627-009-220-046, 627-009-220-047, and 627-009-220-048 connectors provide functional equivalence with maintained current rating (3A per contact) and operating temperature range (-55°C ~ 85°C). These parts are active production items with ROHS3 compliance. The 627 series differs in shell material finish (Nickel Plated) and includes shielding features in certain variants. The 627-009-220-042 and 627-009-220-047 include board lock features matching the main part specification.
Alternative Substitutes (NorComp Series):
The NorComp 171-009-113R001 and 172-009-112R911 connectors provide 9-position D-Sub plug functionality with panel mount capability. The 171-009-113R001 is active production with 5A current rating and gold contact finish. The 172-009-112R911 is obsolete but ROHS3 compliant with board lock features. Both NorComp parts support the required shell size and solder termination.
Alternative Substitute (HARTING 09641227235):
The HARTING 09641227235 provides the highest current rating (7.5A) and extended operating temperature range (-20°C ~ 125°C). This part is active production and ROHS3 compliant. The voltage rating (100V) is lower than the main part (250V), requiring circuit-level verification. The HARTING connector includes filter features and machined contacts.
Regulatory Compliance Consideration:
The main part 1-1634218-2 is RoHS non-compliant and REACH affected. All substitute parts listed are ROHS3 compliant, with most marked as REACH unaffected. Selection of substitute parts addresses regulatory requirements for new designs and ongoing production.
Frequently Asked Questions (FAQ)
Q: Can the 2301826-1 directly replace the 1-1634218-2 in existing applications?
A: The 2301826-1 maintains identical connector geometry, shell size, position count, and solder termination. The current rating is reduced from 3A to 1.5A. Direct replacement is possible only if circuit current requirements do not exceed 1.5A per contact. Electrical circuit analysis is required to confirm compatibility.
Q: What is the difference between the Mercury 627-009-220-042 and 627-009-220-046?
A: Both connectors are functionally equivalent with identical electrical ratings (3A per contact, -55°C ~ 85°C operating range) and shell configuration. The primary difference is packaging: 627-009-220-042 is supplied in trays, while 627-009-220-046 is supplied in tubes. The 627-009-220-046 includes board lock features; the 627-009-220-042 does not explicitly list board lock in its feature set.
Q: Why does the HARTING 09641227235 have a lower voltage rating than the main part?
A: The HARTING connector is rated for 100V, while the main part is rated for 250V. This represents a design difference between manufacturers. Circuit voltage requirements must be verified before substitution. If the application requires 250V rating, the HARTING part is not suitable.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant. The main part 1-1634218-2 is RoHS non-compliant. Substitution with any listed part addresses RoHS compliance requirements for new designs and manufacturing transitions.
Q: Can NorComp panel mount connectors replace through-hole only connectors?
A: The NorComp 171-009-113R001 and 172-009-112R911 support both panel mount and through-hole mounting. These parts can replace through-hole only connectors. The additional panel mount capability does not prevent through-hole installation.
Q: What is the significance of the contact finish thickness specification?
A: The main part specifies 15.0µin (0.38µm) gold contact finish thickness. The 2301826-1 maintains this specification. Mercury and NorComp parts specify flash gold finish, which is thinner. Flash finish provides adequate contact protection for signal-level applications but may have different wear characteristics in high-cycle mating applications.
Q: Which substitute part has the best inventory availability?
A: The NorComp 171-009-113R001 has the highest inventory level at 8772 units in stock. The TE Connectivity 2301826-1 has 2400 units available. Mercury United Electronics 627-009-220-048 has 2058 units in stock. Inventory levels support component selection based on delivery requirements.
Q: Are there temperature range limitations with any substitute parts?
A: The main part operates from -55°C to 105°C. The Mercury 627 series is limited to -55°C ~ 85°C, representing a 20°C reduction in maximum operating temperature. The HARTING part extends to 125°C maximum. Applications requiring operation above 85°C must use the main part, 2301826-1, or HARTING alternative.
Q: What mounting configuration differences exist between substitute parts?
A: The main part specifies through-hole mounting with housing/shell flange (4-40). Most substitutes use board-side flange (4-40) configuration. The NorComp parts support panel mount in addition to through-hole. Flange configuration affects PCB layout and mechanical mounting design.
