Engineering Selection Recommendations
Primary Substitutes (Full Compatibility):
NorComp 171-025-113R051 and Amphenol L717SDB25POL2 are the preferred substitutes. Both maintain ROHS3 compliance, UL94 V-0 flammability rating, and gold-plated contacts. The Amphenol part matches the full operating temperature range (-55°C to 125°C) of the HARTING original. The NorComp 171-025-113R051 includes board lock and grounding indents features, with MSL 1 (Unlimited) moisture sensitivity rating matching the main part.
Secondary Substitutes (Temperature Derating Required):
NorComp 171-025-113R001, 171-025-113R011, 171-025-113R021, and 171-025-113R031 are suitable for applications where the upper operating temperature limit of 100°C is acceptable. All maintain ROHS3 compliance and UL94 V-0 rating. These parts differ in flange feature configuration (housing/shell unthreaded, board side, or mating side), allowing selection based on specific mounting requirements.
Limited Substitution (Current Derating Required):
Mercury 627-025-220-017 is suitable only for applications where the current requirement does not exceed 3A per contact. This part operates to 85°C maximum and includes shielding features. Current rating of 3A per contact is below the main part specification of 6.5A and restricts application scope.
Non-Substitutable Alternative:
TE Connectivity 1218124-3 is excluded from substitution due to RoHS non-compliance status, which conflicts with the ROHS3 compliant main part specification.
Frequently Asked Questions (FAQ)
Q: Can NorComp 171-025-113R051 directly replace HARTING 09653296702 in all applications?
A: Yes, for applications operating within -50°C to 100°C. The NorComp part maintains identical 25-position D-Sub configuration, gold-plated contacts, UL94 V-0 flammability, ROHS3 compliance, and includes board lock and grounding indents. If your application requires operation above 100°C or below -50°C, the Amphenol L717SDB25POL2 is the preferred choice due to its -55°C to 125°C operating range.
Q: What is the impact of current rating differences between the main part (6.5A) and substitute parts (3A to 5A)?
A: Current rating determines maximum allowable current per contact. The HARTING 09653296702 is rated 6.5A, while most NorComp substitutes are rated 5A and Mercury 627-025-220-017 is rated 3A per contact. If your circuit design requires current above 5A per contact, only the Amphenol L717SDB25POL2 (3A rating) or Mercury part would require design review. For applications at or below 5A, NorComp substitutes are fully compatible.
Q: Are panel mount variants (NorComp 171-025-113R011, 171-025-113R021, 171-025-113R031) compatible with through-hole PCB designs?
A: NorComp panel mount variants support both panel mount and through-hole termination. The flange feature differences (board side 4-40, mating side 4-40) indicate mounting hole locations but do not prevent through-hole solder termination. Verify your PCB layout accommodates the specific flange configuration before selection.
Q: Why is TE Connectivity 1218124-3 not listed as a substitute?
A: TE Connectivity 1218124-3 is RoHS non-compliant, while the HARTING 09653296702 is ROHS3 compliant. This regulatory status difference disqualifies it from substitution in applications requiring RoHS compliance. Additionally, the TE part is rated 5A versus the HARTING 6.5A specification.
Q: What is the difference between flash gold plating and unspecified gold finish?
A: Flash gold plating is a thin electroplated layer (typically 0.5 to 2 microinches) applied over nickel or copper base material. The HARTING main part does not specify gold finish thickness. Flash plating on substitute parts is standard for D-Sub connectors and provides equivalent contact performance and corrosion resistance for solder termination applications.
Q: Can Mercury 627-025-220-017 be used in high-current applications?
A: Mercury 627-025-220-017 is rated 3A per contact, which is below the HARTING 6.5A specification. This part is suitable only for applications requiring 3A or less per contact. Additionally, its maximum operating temperature is 85°C, limiting use in high-temperature environments. For applications exceeding these limits, select NorComp or Amphenol alternatives.
Q: What packaging format differences exist among substitutes?
A: HARTING 09653296702 is supplied in bulk packaging. Substitute parts are supplied in tray (NorComp, Amphenol) or tube (Mercury) packaging. Packaging format does not affect electrical or mechanical compatibility; it impacts only handling, storage, and procurement logistics.
