Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L17HTNBP4F4C are grouped based on strict adherence to the following critical parameters:

Primary Matching Criteria:

• Connector type: D-Sub plug with male pins
• Position count: 25 positions
• Shell size and layout: 3 (DB, B)
• Mounting configuration: Through hole, right angle orientation
• Termination method: Solder
• Flange feature: Mating side, female screwlock (4-40)

Secondary Compatibility Parameters:

• Current rating: 5A minimum
• Voltage rating: 300V minimum
• Operating temperature range: Must encompass -55°C to 125°C minimum
• Contact finish: Gold plating
• Shell material: Steel with plating
• Dielectric material: Glass-filled thermoplastic or polyamide
• Compliance: RoHS and UL94 V-0 certification

Parts meeting all primary criteria and maintaining compatibility across secondary parameters are classified as direct substitutes. Variations in contact finish thickness (flash vs. 30.0µin), shell plating composition (tin-nickel vs. nickel), or dielectric material formulation (PBT vs. PA9T) do not preclude substitution when electrical and mechanical specifications remain within acceptable ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The parts D25P33E4GV00LF, D25P33E6GV00LF, and 09683637813 provide the closest functional equivalence to L17HTNBP4F4C. These maintain identical connector geometry, position count, mounting orientation, and flange configuration. D25P33E4GV00LF and D25P33E6GV00LF are Amphenol ICC (FCI) Delta D series connectors with matching tin-nickel shell plating and gold contact finish. Part 09683637813 is a HARTING equivalent with mating-side female screwlock flange matching the original specification. All three are RoHS compliant and UL94 V-0 rated.

Secondary Substitutes (Conditional Compatibility):

Parts 182-025-113R181, 182-025-113R171, and 182-025-113R161 from NorComp Inc. are functionally compatible but feature panel mount capability in addition to through-hole mounting. These parts maintain 25 position configuration, right-angle orientation, and solder termination. Operating temperature range is reduced to -55°C to 105°C compared to the original 150°C maximum. Contact finish is gold flash rather than 30.0µin plating. These parts are suitable for applications where the reduced temperature range and flash plating are acceptable.

Alternative Substitutes (Limited Compatibility):

Parts 09683635812 and 09683637812 from HARTING feature housing/shell flange configuration rather than mating-side female screwlock. These are suitable only when flange mounting location flexibility exists. Current rating is elevated to 6.5A, providing margin above the 5A specification. Operating temperature is limited to -55°C to 125°C.

Compliance Considerations:

All substitute parts maintain RoHS compliance and UL94 V-0 flammability rating. Parts from NorComp Inc. (182 series) carry ROHS3 designation. Amphenol ICC (FCI) Delta D series parts carry either RoHS or ROHS3 compliance. HARTING parts are ROHS3 compliant with REACH unaffected status. Selection should account for specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can HARTING part 09683637813 directly replace L17HTNBP4F4C?

A: Yes. Part 09683637813 matches all primary substitution criteria: 25 positions, DB/B shell size, through-hole right-angle mounting, mating-side female screwlock flange (4-40), and solder termination. The 6.5A current rating exceeds the 5A requirement. Operating temperature range (-55°C to 125°C) covers the critical lower and mid-range of the original specification but does not extend to 150°C. This substitution is valid for applications operating within -55°C to 125°C.

Q: What is the difference between flash gold plating and 30.0µin gold plating?

A: Flash gold plating is a thin, minimal gold layer applied for corrosion protection and contact conductivity. The 30.0µin (0.76µm) specification indicates a thicker, more durable gold coating. Both provide adequate contact performance for signal applications. Flash plating is suitable for standard environmental conditions; thicker plating offers enhanced durability in high-cycle mating applications or harsh environments. Selection depends on application duty cycle and environmental exposure.

Q: Are NorComp 182 series connectors suitable replacements?

A: NorComp 182 series parts (182-025-113R161, 182-025-113R171, 182-025-113R181, 182-025-113R531) are mechanically and electrically compatible with L17HTNBP4F4C for applications within their operating temperature range (-55°C to 105°C). These parts feature panel mount capability in addition to through-hole mounting, providing design flexibility. Flange configurations vary: 182-025-113R181 matches the mating-side female screwlock feature; 182-025-113R171 and 182-025-113R531 feature housing/shell (4-40) flanges; 182-025-113R161 features unthreaded housing/shell flange. Contact material is brass rather than copper alloy. These substitutions are valid when temperature range and contact material differences are acceptable.

Q: What is the significance of the flange feature in connector selection?

A: The flange feature determines mechanical mounting and mating interface. Mating-side female screwlock (4-40) flanges, as specified in L17HTNBP4F4C, provide threaded fastening at the connector mating face for secure coupling. Housing/shell flanges provide board-level or panel-level mounting points. Unthreaded housing/shell flanges offer mounting flexibility without threaded fasteners. Flange type selection must match the mechanical interface requirements of the mating connector and mounting structure. Substitution is valid only when flange configuration is compatible with the application's mechanical design.

Q: Can Amphenol ICC (FCI) Delta D series parts replace the HTN series original?

A: Yes. Delta D series parts D25P33E4GV00LF, D25P33E4GX00LF, and D25P33E6GV00LF are direct functional equivalents. All maintain 25 position configuration, DB/B shell size, through-hole right-angle mounting, and solder termination. D25P33E4GV00LF and D25P33E6GV00LF feature mating-side female screwlock flanges matching the original. D25P33E4GX00LF features housing/shell (4-40) flange. Voltage rating is 300V compared to the original 600V, which is acceptable for signal-level applications. Operating temperature range is -55°C to 125°C. These parts are RoHS or ROHS3 compliant and UL94 V-0 rated.

Q: Does packaging type (tray vs. bulk) affect electrical or mechanical performance?

A: No. Packaging type (tray or bulk) is a logistics and handling specification that does not affect connector electrical performance, mechanical compatibility, or functional characteristics. Selection between tray and bulk packaging depends on inventory management, handling procedures, and supply chain requirements rather than application engineering criteria.
