Substitute Part Grouping Explanation

Substitution eligibility for the PCN10-20P-2.54DSA is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 20 positions, 2 rows, 0.100" (2.54mm) pitch, Style B
• Electrical Characteristics: 2A current rating, gold contact finish at 8.00µin thickness
• Mechanical Interface: Through-hole solder termination, male pin orientation
• Environmental Specifications: Operating temperature range -55°C ~ 85°C, UL94 V-0 flammability rating
• Material Composition: PBT insulation material, MSL 1 classification

The substitute part PCN10-20P-2.54DSA(72) maintains identical electrical, mechanical, and environmental specifications while differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The PCN10-20P-2.54DSA(72) is the direct functional equivalent of the obsolete PCN10-20P-2.54DSA. Both parts share identical electrical, mechanical, and environmental specifications. The primary distinctions are:

Product Status: The substitute part is active, ensuring long-term availability and manufacturing support, whereas the main part is obsolete and subject to discontinuation.

Compliance: The substitute part achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets. The original part is RoHS non-compliant.

Packaging: The substitute is supplied in tray packaging, which may affect handling, storage, and assembly processes compared to bulk packaging.

For new designs or production continuity, the PCN10-20P-2.54DSA(72) is the appropriate selection. Existing designs using the obsolete part number can transition to this substitute without modification to PCB layouts, assembly procedures, or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are the PCN10-20P-2.54DSA and PCN10-20P-2.54DSA(72) mechanically interchangeable?

A: Yes. Both parts are identical in connector configuration, pin pitch (0.100" / 2.54mm), mounting type (through-hole), and physical dimensions. They are direct mechanical substitutes.

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

A: The primary differences are packaging format (bulk versus tray) and product status (obsolete versus active). The electrical and mechanical specifications are identical.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. RoHS3 compliance indicates improved environmental and regulatory alignment. The substitute part maintains all electrical and mechanical characteristics of the original part.

Q: Can I use the PCN10-20P-2.54DSA(72) in existing assemblies designed for the PCN10-20P-2.54DSA?

A: Yes. The substitute part is fully compatible with existing PCB designs and assembly processes. No design modifications are required.

Q: What is the significance of the "(72)" designation in the part number?

A: The "(72)" suffix indicates the packaging configuration (tray packaging with 72 units per tray). This is a packaging variant of the base part number PCN10-20P-2.54DSA.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate within the same temperature range (-55°C ~ 85°C) and carry the same current rating (2A). Performance is equivalent.
