Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P8-12S-C(02) is determined by the following critical parameters:

• Series compatibility: Both parts must belong to the QR/P8 series
• Connector type: Housing for female sockets configuration
• Number of positions: 12-position requirement
• Number of rows: 2-row configuration
• Mounting type: Panel mount orientation
• Connector usage: Receptacle function
• RoHS compliance: Maintained across substitutes

The identified substitute QR/P8-12S-C(22) maintains all core functional parameters within the QR/P8 series architecture. However, this substitute introduces a pitch variation (0.177" / 4.50mm versus 0.079" / 2.00mm) and color differentiation (blue versus black housing), which represent design-level changes that must be evaluated within the context of specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The QR/P8-12S-C(22) is the designated substitute for the obsolete QR/P8-12S-C(02). Both components maintain RoHS compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The substitute part carries active product status, providing assured long-term availability and supply chain stability compared to the obsolete original.

Selection of the QR/P8-12S-C(22) requires verification that the pitch modification (2.00mm to 4.50mm) and housing color change (black to blue) align with the mechanical and visual requirements of the target application. These parameters directly affect PCB layout, mating interface geometry, and system identification protocols.

Frequently Asked Questions (FAQ)

Q: Can QR/P8-12S-C(22) directly replace QR/P8-12S-C(02) in existing assemblies?

A: Direct mechanical replacement is not guaranteed. The pitch change from 0.079" (2.00mm) to 0.177" (4.50mm) alters the contact spacing and overall connector footprint. PCB layout and mating connector compatibility must be verified before substitution.

Q: What is the significance of the pitch difference between these two parts?

A: Pitch defines the center-to-center distance between connector positions. The QR/P8-12S-C(02) uses 2.00mm pitch, while the QR/P8-12S-C(22) uses 4.50mm pitch. This difference affects the physical dimensions of the connector housing and requires corresponding changes to mating components and PCB design.

Q: Does the color change from black to blue affect electrical performance?

A: Color is a cosmetic and identification parameter that does not affect electrical function. The blue housing of the QR/P8-12S-C(22) provides visual differentiation but maintains identical electrical characteristics and performance specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both QR/P8-12S-C(02) and QR/P8-12S-C(22) are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), ensuring compatibility with modern manufacturing and environmental standards.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates that the QR/P8-12S-C(02) is no longer in active production. The QR/P8-12S-C(22) represents the active product line continuation within the QR/P8 series, ensuring ongoing availability and support.

Q: What packaging is available for the substitute part?

A: The QR/P8-12S-C(22) is supplied in bulk packaging, differing from the original part's packaging specification. Confirm packaging requirements with procurement specifications before ordering.
