Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 749914-2 backshell connector is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 9
• Compatible Shell Size: E
• Compatible D-Sub Size: 9pos and HD15pos
• Cable Exit Angles: 120°, 180°
• Cable Type: Round
• Shielding: Unshielded
• Material: Polypropylene (PP)
• Color: Black
• Accessory Type: Hinged Backshell
• Series: AMPLIMITE Quik-Snap

All identified substitute parts maintain identical electrical and mechanical specifications across these parameters. Variations in product status, packaging format, and regulatory compliance certifications do not affect functional interchangeability within the connector assembly.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5749914-1

The 5749914-1 is the preferred substitute for the obsolete 749914-2. This part maintains complete functional and mechanical equivalence while offering superior regulatory compliance status. The 5749914-1 is classified as Active product status, ensuring continued availability and manufacturer support. This part achieves ROHS3 compliance and carries REACH Affected designation, meeting current environmental and regulatory requirements for new designs and procurement cycles. Packaging is provided in Box format, suitable for controlled inventory management.

Secondary Alternative: 5749914-2

The 5749914-2 provides functional equivalence identical to the main part and is available in higher inventory quantity (1209 pieces). This part achieves ROHS3 compliance. However, it retains Obsolete product status classification, limiting long-term availability assurance. Packaging is provided in Bulk format. This option is suitable for immediate replacement needs where inventory availability is prioritized.

Regulatory Compliance Consideration

The main part 749914-2 is RoHS non-compliant. Both substitute parts (5749914-1 and 5749914-2) achieve ROHS3 compliance, representing an improvement in environmental regulatory alignment. Selection between substitutes should account for system-level compliance requirements and procurement timelines.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 5749914-1 and 5749914-2 mechanically interchangeable with 749914-2?

A: Yes. Both substitute parts maintain identical mechanical specifications including shell size (E), position count (9), cable exit angles (120°, 180°), material composition (Polypropylene), and compatibility with 9-position and HD15-position D-Sub connectors. Direct substitution is supported without modification to connector assemblies or cable routing.

Q: What is the difference between 5749914-1 and 5749914-2?

A: The parts are functionally and mechanically identical. Primary differences are: (1) Product Status—5749914-1 is Active while 5749914-2 is Obsolete; (2) Packaging—5749914-1 is supplied in Box format while 5749914-2 is supplied in Bulk format; (3) REACH Status—5749914-1 is REACH Affected while 5749914-2 is Vendor Undefined. Both achieve ROHS3 compliance.

Q: Why is the original part 749914-2 classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued active production and support for this part number. Substitute parts with Active status provide assurance of continued availability and manufacturer technical support.

Q: Does the packaging format affect connector performance?

A: No. Packaging format (Box versus Bulk) does not affect electrical or mechanical performance. Packaging selection is determined by inventory management requirements, quantity needs, and procurement procedures.

Q: Are there any environmental or compliance advantages to selecting a substitute part?

A: Yes. The original part 749914-2 is RoHS non-compliant. Both substitute parts achieve ROHS3 compliance, meeting current environmental regulations. The 5749914-1 additionally carries REACH Affected designation, providing enhanced regulatory documentation for systems requiring compliance verification.

Q: Can 5749914-1 and 5749914-2 be used interchangeably in the same assembly?

A: Yes. Both parts are functionally and mechanically equivalent and can be used interchangeably within the same connector assembly without performance impact.

Q: What is the moisture sensitivity level for these backshell connectors?

A: All three parts (749914-2, 5749914-1, and 5749914-2) carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or installation.
