L17HTNBGSOL2RM81CALC Equivalent & Substitute Parts

Part Overview

The L17HTNBGSOL2RM81CALC is a 25-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features female sockets with a mating-side female screwlock (M3) and is designed for signal applications requiring robust electrical connectivity in industrial and commercial environments. The connector is currently in active production status with 802 units in stock. Identifying equivalent and substitute parts is necessary to ensure supply chain continuity, manage component availability across different procurement channels, and support design flexibility when the primary part becomes unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L17HTNBGSOL2RM81CALC is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Type: Signal
• Current Rating: 5A
• Contact Finish: Gold
• Color: Black

Allowable Variation Parameters:

• Shell Material and Finish (Steel, Nickel Plated vs. Steel, Cadmium Plated)
• Operating Temperature Range (within overlapping bounds)
• Flange Feature configuration (Mating Side Female Screwlock vs. Housing/Shell Unthreaded)
• Contact Finish Thickness specifications
• Voltage Rating (when substitute meets or exceeds primary specification)

The substitute part M24308/23-9F meets all mandatory matching criteria and operates within compatible electrical and mechanical parameters. Variations in shell finish material and flange feature design do not compromise functional interchangeability in applications where the primary connector specifications are met.

Engineering Selection Recommendations

L17HTNBGSOL2RM81CALC (Primary Part):

• Select when UL94 V-0 flammability certification is required
• Select when operating temperature must reach 150°C
• Select when 600V voltage rating specification is mandatory
• Select when nickel-plated shell finish is specified for corrosion resistance in specific environments
• Select when mating-side female screwlock (M3) flange feature is required for mechanical retention

M24308/23-9F (Substitute Part):

• Select when MIL-DTL-24308 military specification compliance is required
• Select when cadmium-plated shell finish meets environmental specifications
• Select when operating temperature maximum of 125°C is acceptable
• Select when housing/shell unthreaded flange feature is compatible with application design
• Select when AMPLIMITE 109 series designation aligns with system requirements
• Select when REACH-affected material status is acceptable for the application

Both parts are RoHS non-compliant and share identical electrical contact specifications (5A current rating, gold contact finish, signal contact type). Selection between these parts depends on specific compliance requirements, environmental conditions, and mechanical interface specifications rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can M24308/23-9F directly replace L17HTNBGSOL2RM81CALC in all applications?

A: M24308/23-9F is electrically and mechanically compatible for applications where the operating temperature does not exceed 125°C, UL94 V-0 flammability certification is not required, and the housing/shell unthreaded flange feature is acceptable. The 600V voltage rating of the primary part is not specified for the substitute; verify voltage requirements against application specifications.

Q: What is the significance of the shell material difference (Nickel Plated vs. Cadmium Plated)?

A: Shell material finish affects corrosion resistance and environmental durability. Nickel plating provides superior corrosion resistance in harsh environments. Cadmium plating is specified in military applications per MIL-DTL-24308. Selection depends on environmental exposure and compliance requirements.

Q: Are the flange features interchangeable?

A: The primary part features a mating-side female screwlock (M3) for mechanical retention. The substitute features an unthreaded housing/shell flange. These are mechanically different and may not be interchangeable depending on the mating connector design and mechanical retention requirements of the application.

Q: What is the impact of the 25°C temperature range difference?

A: The primary part operates to 150°C; the substitute to 125°C. Applications requiring operation above 125°C must use the primary part. Applications with maximum operating temperature of 125°C or below can use either part.

Q: Are both parts suitable for RoHS-compliant applications?

A: No. Both L17HTNBGSOL2RM81CALC and M24308/23-9F are RoHS non-compliant. Neither part is suitable for applications requiring RoHS compliance.

Q: What is the inventory status for each part?

A: L17HTNBGSOL2RM81CALC has 802 units in stock. M24308/23-9F has 1053 units in stock. Both are available as new original components.

Q: How do the contact materials differ?

A: L17HTNBGSOL2RM81CALC uses copper alloy contacts. M24308/23-9F uses brass contacts. Both materials with gold plating provide equivalent signal integrity and electrical performance for 5A signal applications.
