Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1-207908-3 with the active equivalent 1-5207908-3 is based on strict electrical and mechanical parameter alignment. Both components share identical specifications across all critical functional parameters: 50-position configuration, D-shell size compatibility, support for both 50pos and HD78pos D-Sub sizes, dual cable exit angles (90° and 180°), round cable type, unshielded design, black color, and identical mating hardware (4-40 screws with assembly hardware and strain relief).

The substitution is valid based on the following key parameters:

• Identical accessory type (hinged backshell)
• Identical position count (50)
• Identical shell size compatibility (D)
• Identical D-Sub size compatibility (50pos and HD78pos)
• Identical cable exit angle options (90°, 180°)
• Identical cable type (round)
• Identical shielding configuration (unshielded)
• Identical color (black)
• Identical hardware specifications (4-40 mating screws)

Engineering Selection Recommendations

The 1-5207908-3 is the direct active equivalent for the obsolete 1-207908-3. Selection of the 1-5207908-3 is supported by the following engineering considerations:

Product Status: The 1-5207908-3 maintains active product status with confirmed inventory availability (1491 pieces in stock), ensuring reliable supply for both new designs and field service applications. The original 1-207908-3 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The 1-5207908-3 achieves RoHS compliance, meeting current environmental and regulatory requirements for electronic components in regulated markets. The original part carries RoHS non-compliant status. Additionally, the 1-5207908-3 is designated as REACH Affected, providing documented regulatory status for supply chain transparency.

Functional Equivalence: All electrical and mechanical parameters remain identical between the two components, ensuring direct interchangeability in existing designs without circuit or mechanical modifications.

Material Specification: While both components are plastic-based, the 1-5207908-3 specifies polypropylene (PP) material composition, providing documented material traceability compared to the generic plastic designation of the obsolete part.

Frequently Asked Questions (FAQ)

Q: Can the 1-5207908-3 directly replace the 1-207908-3 in existing assemblies?

A: Yes. Both components share identical specifications for all functional parameters including position count, shell size, cable exit angles, cable type, shielding configuration, and hardware features. Direct substitution is supported without design modifications.

Q: What is the difference in packaging between these two parts?

A: The 1-207908-3 does not specify packaging format in available documentation. The 1-5207908-3 is supplied in bag packaging. This difference does not affect functional performance or compatibility.

Q: Are there any material differences between the two components?

A: The 1-207908-3 is designated as thermoplastic material. The 1-5207908-3 specifies polypropylene (PP) as the material composition. Both are plastic-based and functionally equivalent. The polypropylene specification in the active part provides greater material traceability.

Q: Why is the 1-207908-3 listed as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The active equivalent 1-5207908-3 provides continued access to the same functional capability within the AMPLIMITE HD-20 series.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance status reflects regulatory and environmental standards adherence. The 1-5207908-3 RoHS compliant status meets current regulatory requirements for many markets. Functional compatibility between the two components remains unchanged.

Q: Are both components suitable for the same D-Sub connector sizes?

A: Yes. Both the 1-207908-3 and 1-5207908-3 are compatible with 50-position and HD78-position D-Sub connectors with D-shell size configuration.

Q: What cable exit angle options are available?

A: Both components support 90° and 180° cable exit angles, providing flexibility for various installation orientations and space constraints.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
