L17HTNAGPOL2RM81C D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The L17HTNAGPOL2RM81C is a 15-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features male pins with a mating-side female screwlock (M3) and is designed for signal applications requiring robust mechanical and electrical performance. The connector is currently active in production with 1090 pieces in stock. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L17HTNAGPOL2RM81C is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 15
• Number of rows: 2
• Shell size and layout: 2 (DA, A)
• Mounting type: Through Hole
• Termination method: Solder
• Contact type: Signal
• Material flammability rating: UL94 V-0
• Current rating: 5A minimum
• Operating temperature range: Must encompass or exceed -55°C ~ 150°C
• Features: Board Lock, Grounding Indents

Allowable Variations:

• Shell material finish: Steel with different plating (Nickel, Tin-Nickel)
• Contact material: Copper Alloy or Phosphor Bronze
• Dielectric material: Thermoplastic Glass Filled or Polybutylene Terephthalate (PBT)
• Voltage rating: Equal to or greater than 600V
• Flange screwlock specification: M3 or 4-40 (mechanical equivalence)
• RoHS compliance status: May differ based on application requirements
• Manufacturer: Different divisions or manufacturers within Amphenol ICC family

The substitute part D15P24A4GV00LF meets all mandatory matching parameters and allowable variations, qualifying it as a direct functional equivalent.

Engineering Selection Recommendations

Primary Part: L17HTNAGPOL2RM81C

Select this part when:

• Application voltage requirement is 600V
• Operating temperature must reach 150°C
• RoHS non-compliance is acceptable or required by design specification
• Copper alloy contact material is specified
• Nickel-plated shell finish is required

Substitute Part: D15P24A4GV00LF

Select this part when:

• Application voltage requirement is 300V or lower
• Operating temperature maximum is 125°C or lower
• RoHS compliance is required
• Phosphor bronze contact material is acceptable
• Tin-nickel plated shell finish is acceptable
• 4-40 screwlock specification is compatible with mating hardware
• Supply of primary part is unavailable

Both parts share identical mechanical footprint, pin configuration, and core electrical characteristics within their respective rated parameters. Selection between them depends on voltage, temperature, and compliance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q1: Can D15P24A4GV00LF be used as a direct replacement for L17HTNAGPOL2RM81C in all applications?

A: No. The substitute part has lower voltage (300V vs. 600V) and temperature (125°C vs. 150°C) ratings. Verify that your application operates within these reduced limits before substitution.

Q2: What is the difference between M3 and 4-40 screwlock specifications?

A: M3 refers to metric thread (3mm diameter), while 4-40 refers to UNC (Unified National Coarse) thread specification. Both provide mechanical locking function. Ensure your mating connector or hardware accommodates the screwlock type of your selected part.

Q3: Are the contact materials interchangeable?

A: Copper alloy and phosphor bronze contacts are functionally equivalent for signal applications at the specified current and voltage ratings. Both materials provide adequate conductivity and mechanical durability. Selection depends on application-specific requirements and availability.

Q4: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition restrictions (lead, cadmium, mercury, etc.), not electrical performance. The RoHS-compliant substitute (D15P24A4GV00LF) performs identically to the non-compliant primary part within its rated parameters.

Q5: Can I use the substitute part in a 600V application?

A: No. The substitute part is rated for 300V maximum. Using it in a 600V application exceeds its electrical rating and creates safety and reliability risks.

Q6: What is the difference between nickel plating and tin-nickel plating?

A: Both finishes provide corrosion resistance on the steel shell. Tin-nickel plating offers enhanced corrosion resistance in certain environments. For standard applications, both are functionally equivalent.

Q7: Are the dielectric materials (thermoplastic glass-filled vs. PBT) interchangeable?

A: Yes. Both materials meet UL94 V-0 flammability requirements and provide adequate electrical insulation at the specified voltage and temperature ratings. PBT offers slightly different mechanical properties but is functionally equivalent for this connector application.

Q8: What inventory considerations should I account for?

A: Primary part L17HTNAGPOL2RM81C has 1090 pieces in stock. Substitute part D15P24A4GV00LF has 1867 pieces in stock. If supply constraints exist for the primary part, the substitute offers greater availability.

Q9: Are there any packaging differences between these parts?

A: Both parts are supplied in tray packaging. No special handling or storage differences apply between them.

Q10: How do I verify compatibility with my existing PCB design?

A: Confirm that your design accommodates the following: 15-position D-Sub plug configuration, through-hole solder termination, 2-row layout (DA, A shell size), and the specific screwlock type (M3 or 4-40) of your selected connector. Mechanical footprint and pin assignment are identical between both parts.
