Engineering Selection Recommendations

For applications requiring the full operational temperature range (-55°C to 150°C):

The L17HTNBHPOL2RM84C is the only part in this equivalency group rated to 150°C. Amphenol ICC (FCI) Delta D series parts (D25P24A4GV00LF, D25P24A4GX00LF, D25P24A4PL00LF, D25P24A6GV00LF, D25P24B4GV00LF, D25P24B6GV00LF, and DB25P364TXLF) are rated to 125°C maximum. HARTING parts are rated to 125°C. TE Connectivity 2-338311-2 is rated to 105°C. Selection must accommodate design operating temperature requirements.

For 600V applications:

Only L17HTNBHPOL2RM84C is rated for 600V operation. Amphenol ICC (FCI) Delta D parts are rated to 300V. TE Connectivity 2-338311-2 is rated to 125V. HARTING parts list voltage rating as unspecified. Voltage rating requirements dictate part selection.

For RoHS compliance scope:

The original L17HTNBHPOL2RM84C is RoHS non-compliant. All Amphenol ICC (FCI) Delta D series parts (D25P24A4GV00LF, D25P24A4GX00LF, D25P24A4PL00LF, D25P24A6GV00LF, D25P24B4GV00LF, D25P24B6GV00LF) and DB25P364TXLF are RoHS compliant. HARTING 09653216703 and 09653616713 are ROHS3 compliant. TE Connectivity 2-338311-2 is ROHS3 compliant. Regulatory requirements determine compliance necessity.

For packaging format:

L17HTNBHPOL2RM84C is supplied in tray format. HARTING 09653216703 and TE Connectivity 2-338311-2 are supplied in bulk. All Amphenol ICC (FCI) Delta D variants and DB25P364TXLF are supplied in tray format, supporting standard inventory management.

For full functional substitution (no operational envelope reduction):

No complete functional equivalent exists. Any substitution involves acceptance of reduced voltage rating (300V vs. 600V) and/or reduced upper temperature limit (125°C or 105°C vs. 150°C). Amphenol ICC (FCI) Delta D series provides RoHS compliance option with interface compatibility but operational envelope constraints.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 2-338311-2 substitute for L17HTNBHPOL2RM84C in all applications?

A: No. The 2-338311-2 has a maximum voltage rating of 125V, compared to 600V for the L17HTNBHPOL2RM84C, and a maximum operating temperature of 105°C versus 150°C. It is suitable only for applications with voltage requirements below 125V and operating temperatures below 105°C. The flange feature differs mechanically (board side M3 versus mating side female screwlock 4-40).

Q: What is the difference between the HARTING 09653216703 and 09653616713?

A: Both are 25-position D-Sub solder plugs with identical electrical parameters (6.5A current rating, -55°C to 125°C operating temperature). The primary difference is packaging: 09653216703 is supplied in bulk format, while 09653616713 is supplied in tray format. The 09653616713 includes a board lock feature, while 09653216703 does not.

Q: Are all Amphenol ICC (FCI) Delta D parts interchangeable with the L17HTNBHPOL2RM84C?

A: They share the same 25-position, 2-row, Size 3 (DB, B) D-Sub plug configuration and solder termination method, making them mechanically and electrically interchangeable from a pin interface perspective. However, they all operate at maximum 125°C (versus 150°C for the L17HTNBHPOL2RM84C) and 300V (versus 600V). The flange features vary: some have mating-side female screwlock (4-40), others have housing/shell mounting (M3 or unthreaded). Contact finish thickness also varies (flash versus 30.0µin plating).

Q: Which substitute parts are RoHS compliant?

A: Amphenol ICC (FCI) Delta D series (D25P24A4GV00LF, D25P24A4GX00LF, D25P24A4PL00LF, D25P24A6GV00LF, D25P24B4GV00LF, D25P24B6GV00LF) are RoHS compliant. DB25P364TXLF is RoHS compliant. HARTING 09653216703 and 09653616713 are ROHS3 compliant. TE Connectivity 2-338311-2 is ROHS3 compliant. The original L17HTNBHPOL2RM84C is RoHS non-compliant.

Q: How do contact finish differences affect connector performance?

A: All parts in this equivalency group have gold or tin-based contact finishes meeting solder joint reliability requirements. Flash thickness gold plating and 30.0µin (0.76µm) thickness gold plating both provide adequate contact resistance and corrosion protection. Tin and tin-nickel plated shell materials provide mechanical durability. Material selection is application-dependent based on environmental exposure and current-carrying requirements.

Q: What flange feature differences exist, and do they affect substitutability?

A: L17HTNBHPOL2RM84C features a mating-side female screwlock (4-40) for threaded coupling. D25P24A4GX00LF and D25P24A4PL00LF have housing/shell mounting (4-40 and M3 respectively). DB25P364TXLF has housing/shell unthreaded mounting. HARTING and TE Connectivity parts have different mechanical interfaces. Flange feature selection is determined by the mating connector or enclosure mounting requirements. Mechanical interface compatibility must be verified independently.

Q: Can the L17HTNBHPOL2RM84C be replaced in legacy designs without performance degradation?

A: Substitution is application-specific. If the design operates within 300V and below 125°C, multiple Amphenol ICC (FCI) Delta D variants provide suitable replacements with RoHS compliance advantage. If the design requires 600V operation or 150°C temperature performance, no suitable substitute exists within this equivalency group, and the original part or a custom solution is required.
