Parameter Comparison

Engineering Selection Recommendations

Primary Selection: L717DFBH25P

The L717DFBH25P remains the preferred selection for new designs and applications requiring panel mount configuration. This part maintains active production status, ensuring long-term availability and supply chain stability. RoHS compliance and UL94 V-0 flammability rating satisfy modern regulatory requirements. The specified operating temperature range of -55°C ~ 125°C and 7.5A current rating support demanding industrial applications.

Secondary Selection: DBP25P065TXLF

The DBP25P065TXLF serves as the primary equivalent substitute when supply constraints affect the L717DFBH25P. This part is manufactured by Amphenol ICC (FCI), maintaining consistency within the Amphenol product ecosystem. Active production status ensures continued availability. The DBP25P065TXLF exceeds the voltage rating specification (1000V versus 300V) and matches the current rating (7.5A per contact). Operating temperature range (-55°C ~ 125°C) and flammability rating (UL94 V-0) are identical to the main part.

The primary distinction is mounting type: DBP25P065TXLF is configured for free hanging (in-line) installation rather than panel mount. This difference requires mechanical redesign of the connector interface but does not affect electrical performance or signal integrity. ROHS3 compliance and enhanced contact finish thickness (30.0µin) provide additional reliability margins.

Tertiary Selection: 172-025-102R001

The 172-025-102R001 is classified as obsolete and should be selected only when existing inventory must be maintained or legacy system repairs require exact part matching. This NorComp Inc. part maintains panel mount configuration matching the L717DFBH25P. However, the current rating (5A) is reduced compared to the main part specification (7.5A), limiting applicability to lower-power signal transmission scenarios.

The operating temperature range (-50°C ~ 100°C) does not fully encompass the L717DFBH25P specification (-55°C ~ 125°C), restricting use in extreme temperature environments. Obsolete product status indicates discontinued manufacturing, creating long-term supply uncertainty. Selection of this part should be limited to applications where these constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can DBP25P065TXLF replace L717DFBH25P in a panel mount application?

A: DBP25P065TXLF is configured for free hanging (in-line) mounting rather than panel mount. Mechanical redesign of the connector interface is required. Electrical performance and signal integrity are not affected by this substitution. The mounting type difference must be evaluated against specific application requirements and available space constraints.

Q: What is the significance of the current rating difference between L717DFBH25P (7.5A) and 172-025-102R001 (5A)?

A: The current rating specifies the maximum continuous current each contact can safely carry without exceeding temperature limits. The 172-025-102R001 at 5A per contact is suitable only for applications where total current draw remains within this limit. Applications requiring the full 7.5A capability must use L717DFBH25P or DBP25P065TXLF.

Q: Why is 172-025-102R001 listed as obsolete?

A: Obsolete status indicates the manufacturer (NorComp Inc.) has discontinued production of this part. While inventory may remain available through distributors, long-term supply cannot be guaranteed. New designs should not incorporate obsolete parts. Existing systems using this part should transition to active alternatives during planned maintenance cycles.

Q: Are there differences in contact finish quality between the three parts?

A: Contact finish thickness varies: L717DFBH25P (20.0µin), 172-025-102R001 (Flash), and DBP25P065TXLF (30.0µin). All three use gold plating for corrosion resistance and electrical conductivity. DBP25P065TXLF includes GXT™ enhanced plating technology, providing additional durability in high-cycle mating applications. These differences do not affect basic electrical performance in standard signal transmission applications.

Q: What is the impact of operating temperature range differences?

A: L717DFBH25P and DBP25P065TXLF both support -55°C ~ 125°C operation. The 172-025-102R001 is limited to -50°C ~ 100°C. Applications requiring operation below -50°C or above 100°C must use L717DFBH25P or DBP25P065TXLF. Temperature range specifications define the connector's material stability and electrical performance boundaries.

Q: Can these connectors be used interchangeably in existing equipment?

A: Mechanical and electrical interchangeability depends on the specific application. All three parts share identical shell size (3/DB/B), position count (25), and row configuration (2). Panel mount versus free hanging mounting type differences require mechanical evaluation. Existing equipment designed for panel mount installation (L717DFBH25P or 172-025-102R001) cannot directly accept free hanging connectors (DBP25P065TXLF) without mechanical modification.

Q: What does RoHS compliance mean for these connectors?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the connector does not contain lead, cadmium, mercury, hexavalent chromium, or specified brominated flame retardants above regulatory thresholds. L717DFBH25P is RoHS Compliant. Both 172-025-102R001 and DBP25P065TXLF are ROHS3 Compliant, representing the current regulatory standard. All three parts satisfy environmental and safety requirements for commercial and industrial applications.

Q: How does voltage rating affect connector selection?

A: L717DFBH25P is rated for 300V, while DBP25P065TXLF is rated for 1000V. The 172-025-102R001 voltage rating is not specified. Voltage rating defines the maximum potential difference the connector can safely withstand without electrical breakdown. Applications operating at voltages exceeding 300V require DBP25P065TXLF. Standard signal transmission applications at voltages below 300V can use any of the three parts.

Q: What packaging formats are available?

A: L717DFBH25P is supplied in Bag packaging (913 pieces available). The 172-025-102R001 is supplied in Tray packaging (1365 pieces available). DBP25P065TXLF is supplied in Bulk packaging (732 pieces available). Packaging format does not affect connector functionality. Selection should be based on inventory management requirements and procurement quantities.
