Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCN10-90P-2.54DS is determined by strict equivalence across the following critical parameters:

• Connector type and pin configuration (Header, Male Pins, 90 positions)
• Pitch specification (0.100" / 2.54mm)
• Row configuration (2 rows)
• Mounting style (Through Hole, Right Angle)
• Contact material and finish (Gold)
• Electrical ratings (2A current, -55°C ~ 85°C operating range)
• Insulation material (PBT)
• Flammability compliance (UL94 V-0)

The substitute part PCN10-90P-2.54DS(72) maintains identical electrical and mechanical specifications while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

PCN10-90P-2.54DS(72) is the direct functional equivalent for PCN10-90P-2.54DS applications. The substitute part maintains identical electrical performance, mechanical fit, and thermal specifications. The primary distinction is product status: PCN10-90P-2.54DS(72) carries active product status with RoHS compliance certification, whereas the original part is obsolete and RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, PCN10-90P-2.54DS(72) is the appropriate selection. Both parts are manufactured by Hirose Electric Co Ltd within the same PCN10 series, ensuring design compatibility and interchangeability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Are PCN10-90P-2.54DS and PCN10-90P-2.54DS(72) mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pin count (90 positions), pitch (2.54mm), row configuration (2 rows), and mounting style (through-hole right-angle). They are mechanically and electrically interchangeable in PCB designs.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (bulk versus tray) and product lifecycle status. PCN10-90P-2.54DS(72) is the active production variant with RoHS compliance, while PCN10-90P-2.54DS is obsolete and RoHS non-compliant.

Q: Can I use PCN10-90P-2.54DS(72) as a direct replacement in existing designs?

A: Yes. The substitute part maintains all critical electrical and mechanical parameters. No design modifications are required for substitution.

Q: Does the packaging difference affect connector performance?

A: No. Packaging format (bulk or tray) does not affect electrical performance, thermal ratings, or mechanical fit. The difference is logistical only.

Q: What is the RoHS compliance difference, and does it matter for my application?

A: PCN10-90P-2.54DS(72) is RoHS compliant; the original part is not. RoHS compliance is mandatory for products sold into regulated markets (EU, China, and others). If your application or end market requires RoHS compliance, PCN10-90P-2.54DS(72) is the required selection.

Q: Are both parts still available for purchase?

A: PCN10-90P-2.54DS is obsolete. PCN10-90P-2.54DS(72) is active production status with current inventory availability.
