Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SQR322110-4 are qualified based on electrical and mechanical parameter alignment within the Amphenol PCD rectangular connector product line. The following parameters establish substitution eligibility:

Critical Parameters for Substitution:

• Connector Type: Plug (matching form factor)
• Contact Type: Female Socket (matching contact configuration)
• Number of Positions: 4 (matching circuit count)
• Number of Rows: 1 (matching layout topology)
• Mounting Type: Free Hanging (In-Line) (matching mechanical interface)
• Contact Termination: Crimp (matching termination method)
• Fastening Type: Latch Lock (matching mechanical lock mechanism)
• Insulation Material: Polyetherimide (PEI) (matching housing material)
• Operating Temperature Range: -65°C to 150°C (matching thermal envelope)
• Features: IP67 (matching environmental sealing)
• RoHS Status: RoHS Compliant (matching regulatory compliance)

SQR422150 qualifies as a direct functional equivalent based on full alignment across all critical parameters. The primary distinction is product status: SQR322110-4 is obsolete while SQR422150 is active, with availability documented in current inventory.

Parameter Comparison

Engineering Selection Recommendations

For new designs or system replacements, SQR422150 is the appropriate selection. This part maintains full functional and mechanical compatibility with the obsolete SQR322110-4 while offering the advantage of active product status and documented current inventory availability (835 pieces). Both parts maintain RoHS compliance, thermal performance across the identical -65°C to 150°C operating range, and equivalent sealing performance (IP67). The transition from SQR322110-4 to SQR422150 requires no design modifications and presents no compliance or performance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can SQR422150 directly replace SQR322110-4 in existing applications? A: Yes. SQR422150 is functionally and mechanically equivalent. All electrical and mechanical parameters are identical, including contact configuration, position count, termination method, fastening mechanism, thermal range, and sealing rating. No design revision is required.

Q: What is the primary reason to transition from SQR322110-4 to SQR422150? A: SQR322110-4 is obsolete with no future production or supply assurance. SQR422150 is an active product with confirmed inventory availability, ensuring reliable procurement for current and future production.

Q: Do both parts require the same contact types? A: Yes. Both housings accommodate female socket contacts with crimp termination. Contacts are not included with the housing and must be procured separately from the same manufacturer's contact portfolio.

Q: Are there any temperature or environmental limitations when substituting? A: No. Both parts operate identically across the -65°C to 150°C range and both provide IP67 environmental sealing. There are no thermal or environmental trade-offs associated with this substitution.

Q: What packaging differences exist between the two parts? A: SQR322110-4 packaging is not specified in the current data. SQR422150 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical functionality; it is a logistics consideration for procurement and inventory management.

Q: Are both parts RoHS compliant? A: Yes. Both SQR322110-4 and SQR422150 are RoHS compliant, maintaining equivalent regulatory status.
