Key Parameters

Substitute Part Grouping Explanation

Substitution of the 207908-7 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Accessory type (hinged backshell)
• Number of positions (25)
• Compatible shell size (B)
• Compatible D-Sub sizes (25pos and HD44pos)
• Cable exit angles (90°, 180°)
• Cable type (round)

Physical & Material Parameters:

• Shielding configuration (unshielded)
• Color (black)
• Hardware specification (mating screws 4-40)

Environmental Parameters:

• Moisture sensitivity level (1 - unlimited)

The substitute part 5207908-7 maintains identical specifications across all mechanical, physical, and environmental parameters. The primary differences between the main part and substitute are product status (obsolete versus active), material composition (thermoplastic versus polypropylene), packaging format (standard versus bulk), and regulatory compliance status (RoHS non-compliant versus RoHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production:

The 5207908-7 is the recommended selection for all new applications and ongoing production requirements. This part maintains full mechanical and electrical compatibility with the 207908-7 while offering the following advantages:

• Active product status ensures continued availability and supply chain support
• RoHS3 compliance satisfies current regulatory requirements for electronic components
• REACH unaffected status provides enhanced environmental and safety compliance documentation
• Polypropylene material composition provides equivalent functional performance to thermoplastic construction

For Legacy System Maintenance:

The 207908-7 remains functionally equivalent to the 5207908-7 for existing installations where regulatory compliance updates are not mandated. Both parts share identical mechanical interfaces, electrical characteristics, and environmental ratings.

Compliance Considerations:

Organizations subject to RoHS3 or REACH regulations must transition to the 5207908-7. The non-compliant status of the 207908-7 may restrict its use in new designs or regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 5207908-7 directly replace the 207908-7 in existing assemblies?

A: Yes. The 5207908-7 maintains identical mechanical compatibility, electrical specifications, and environmental ratings. No design modifications are required for direct substitution.

Q: What is the difference between thermoplastic and polypropylene materials in this application?

A: Both materials provide equivalent functional performance for hinged backshell applications. Polypropylene is a specific thermoplastic polymer that offers the same mechanical strength, temperature stability, and chemical resistance required for D-Sub backshell connectors.

Q: Why is the 207908-7 listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of production. The 5207908-7 serves as the active replacement, offering improved regulatory compliance and continued supply availability.

Q: Are there packaging differences between the two parts?

A: Yes. The 207908-7 is supplied in standard packaging, while the 5207908-7 is available in bulk packaging. Both contain identical components; packaging format differs only for order quantity and logistics purposes.

Q: Does the RoHS3 compliance of the 5207908-7 affect performance in non-regulated applications?

A: No. RoHS3 compliance indicates adherence to hazardous substance restrictions but does not alter electrical or mechanical performance. The 5207908-7 functions identically to the 207908-7 in all applications.

Q: What is the significance of REACH unaffected status?

A: REACH unaffected status confirms that the component does not contain substances of very high concern (SVHC) requiring special documentation or authorization. This simplifies compliance documentation for regulated markets.

Q: Can both parts be used interchangeably in the same production batch?

A: Yes. Mechanical and electrical equivalence permits interchangeable use. However, organizations maintaining RoHS compliance documentation should standardize on the 5207908-7 for consistency.

Q: Is the 4-40 mating screw specification identical on both parts?

A: Yes. Both the 207908-7 and 5207908-7 feature identical 4-40 mating screw hardware, ensuring consistent assembly procedures and tooling requirements.
