Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The D09P24B6GV00LF, D09P24B4GV00LF, D09P24A6GV00LF, and D09P24A4GV00LF parts from Amphenol ICC (FCI) Delta D series maintain solder termination, 5A per contact current rating, and UL94 V-0 flammability compliance. These parts are RoHS Compliant, addressing regulatory requirements not met by the primary part. The D09P24B6GV00LF offers the highest inventory availability (20199 pieces) and maintains the same flange configuration (Mating Side, Female Screwlock 4-40) as the primary part.

Secondary Substitutes (Functional Equivalence with Operational Constraints):

The 5786830-1 from TE Connectivity AMP Connectors (AMPLIMITE HD-20 series) provides a through-hole D-Sub 9-position configuration with RoHS Compliance. However, this part uses press-fit termination rather than solder, operates at a reduced maximum temperature of -55°C ~ 105°C, and does not specify current or voltage ratings. This part is suitable only when press-fit termination is acceptable and operating temperature does not exceed 105°C.

The 09651616713 from HARTING provides a solder-terminated D-Sub 9-position connector with ROHS3 Compliance and higher current rating (6.5A). However, it operates at a reduced maximum temperature of -55°C ~ 125°C and does not specify voltage rating or contact finish. This part is suitable for applications requiring higher current capacity within the reduced temperature range.

Voltage Rating Consideration:

The primary part L17HTNEGPOL2RM81C is rated for 600V. All Amphenol ICC (FCI) Delta D series substitutes are rated for 300V. Applications requiring 600V operation must retain the primary part or select alternatives with equivalent voltage specifications. The TE Connectivity and HARTING alternatives do not specify voltage ratings.

Temperature Range Consideration:

The primary part operates from -55°C to 150°C. Amphenol ICC (FCI) Delta D series substitutes operate from -55°C to 125°C. The TE Connectivity 5786830-1 operates from -55°C to 105°C. Applications requiring operation above 125°C must retain the primary part.

RoHS Compliance:

The primary part is RoHS non-compliant. All listed substitutes are RoHS Compliant or ROHS3 Compliant. Selection of substitute parts addresses RoHS regulatory requirements for new designs or applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can D09P24B6GV00LF directly replace L17HTNEGPOL2RM81C in all applications?

A: D09P24B6GV00LF is functionally compatible for applications operating within -55°C to 125°C and 300V maximum. The primary part operates to 150°C and 600V. Applications requiring these higher specifications must retain the primary part. Both parts use solder termination, maintain 9-position D-Sub configuration, and support 5A per contact current.

Q: What is the difference between the flange configurations in the substitute parts?

A: Flange configuration determines mounting method. "Mating Side, Female Screwlock (4-40)" parts (D09P24A4GV00LF, D09P24A6GV00LF, D09P24B4GV00LF, D09P24B6GV00LF) mount with threaded fasteners on the mating connector side. "Housing/Shell (4-40)" parts (D09P24A4GX00LF, D09P24B4GX00LF) mount with fasteners on the housing. "Housing/Shell (M3)" part (D09P24A4PL00LF) uses M3 metric fasteners. "Housing/Shell (Unthreaded)" part (D09P24A4PA00LF) has no threaded mounting. Selection depends on PCB layout and mechanical mounting requirements.

Q: Why do substitute parts show lower voltage ratings (300V vs. 600V)?

A: Voltage rating is determined by dielectric material properties and contact spacing. The primary part uses glass-filled thermoplastic dielectric rated for 600V. Amphenol ICC (FCI) Delta D series substitutes use polybutylene terephthalate (PBT) dielectric rated for 300V. Applications requiring 600V operation must use the primary part or equivalent 600V-rated alternatives.

Q: Is the TE Connectivity 5786830-1 suitable for new designs?

A: The 5786830-1 is suitable for new designs requiring press-fit termination, RoHS Compliance, and operation within -55°C to 105°C. Press-fit termination eliminates solder processing and provides automated assembly advantages. However, the reduced temperature range and unspecified current/voltage ratings limit applicability. Verify application requirements before selection.

Q: What is the significance of contact material differences (Copper Alloy vs. Phosphor Bronze)?

A: Contact material affects electrical conductivity, wear resistance, and spring characteristics. Copper Alloy provides baseline conductivity. Phosphor Bronze offers enhanced wear resistance and spring properties, improving contact reliability over extended mating cycles. Both materials are acceptable for signal applications; selection depends on expected mating cycle count and contact force requirements.

Q: Are all substitute parts available in the same packaging?

A: No. The primary part L17HTNEGPOL2RM81C is packaged in Tray. Most Amphenol ICC (FCI) substitutes are also Tray packaged. The TE Connectivity 5786830-1 is packaged in Bulk. Packaging affects handling, storage, and assembly processes. Verify packaging compatibility with receiving and assembly procedures.

Q: What does "RoHS non-compliant" mean for the primary part?

A: RoHS non-compliance indicates the primary part may contain restricted substances (lead, cadmium, hexavalent chromium, etc.) above specified thresholds. RoHS Compliant substitutes meet EU Directive 2011/65/EU restrictions. New designs and applications subject to RoHS regulations must use compliant alternatives. Existing designs using the primary part may continue if not subject to regulatory requirements.

Q: Can I use D09P24A4PA00LF with REACH Affected status in regulated applications?

A: D09P24A4PA00LF is marked as REACH Affected, indicating it contains substances of very high concern (SVHC) requiring declaration. Applications subject to REACH regulations must evaluate substance declarations and supply chain documentation. Alternative parts with REACH Unaffected status (D09P24A4GV00LF, D09P24A4GX00LF, D09P24A4PL00LF, D09P24A6GV00LF, D09P24B4GV00LF, D09P24B4GX00LF, D09P24B6GV00LF) may be preferred for REACH-regulated applications.

Q: What is the difference between "Flash" and "30.0µin (0.76µm)" contact finish thickness specifications?

A: "Flash" indicates a thin gold plating applied for corrosion protection without specifying exact thickness. "30.0µin (0.76µm)" specifies exact gold plating thickness of 30 microinches or 0.76 micrometers. Specified thickness provides controlled contact resistance and wear characteristics. Flash plating is suitable for general signal applications; specified thickness is preferred for high-reliability or high-cycle applications.
