Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PQ50SA-1822PCA is determined by the following critical parameters:

• Series designation (PQ50)
• Pin or Socket configuration (Pin)
• Contact Termination method (Crimp)
• Wire Gauge compatibility (18-22 AWG)
• Contact Finish type (Gold)
• Connector Category (Rectangular Connectors)

The substitute part PQ50SA2-1822PCA maintains all these core parameters, ensuring mechanical and electrical compatibility. The primary distinction is the product status transition from obsolete to active, with updated base product numbering (PQ50SA2 versus PQ50SA).

Parameter Comparison

Engineering Selection Recommendations

The PQ50SA2-1822PCA is the manufacturer-recommended substitute for the obsolete PQ50SA-1822PCA. Both parts share identical electrical and mechanical specifications across all critical parameters: wire gauge, contact termination, contact finish, and connector series. The substitute part carries active product status, ensuring continued availability and manufacturing support. Both parts maintain EAR99 export classification and identical HTSUS coding, confirming regulatory equivalence. Selection of the PQ50SA2-1822PCA eliminates obsolescence risk while preserving full functional compatibility with existing connector assemblies and system designs.

Frequently Asked Questions (FAQ)

Q: Are PQ50SA-1822PCA and PQ50SA2-1822PCA mechanically interchangeable?

A: Yes. Both parts are stamped pin contacts within the PQ50 series with identical wire gauge (18-22 AWG), crimp termination, and gold contact finish. They are designed for direct substitution in rectangular connector applications.

Q: What is the difference between the base product numbers PQ50SA and PQ50SA2?

A: The base product number change from PQ50SA to PQ50SA2 reflects a product line update by Hirose Electric. The PQ50SA2 variant represents the active, current production version, while PQ50SA is obsolete. Functional specifications remain equivalent.

Q: Does the substitute part maintain RoHS compliance?

A: The main part PQ50SA-1822PCA is confirmed RoHS Compliant. The substitute part PQ50SA2-1822PCA does not have RoHS status specified in the provided data. Verification with the manufacturer is recommended if RoHS certification is a system requirement.

Q: Are there packaging differences between these parts?

A: The main part packaging is listed as unspecified, while the substitute part is supplied in Bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Can I use PQ50SA2-1822PCA in new designs replacing the obsolete PQ50SA-1822PCA?

A: Yes. The substitute part is the manufacturer-recommended replacement and is suitable for both retrofit applications and new design implementations. Active product status ensures long-term availability.
