Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 61800925311 is determined by the following critical parameters that must remain constant:

• Number of Positions: 9 (fixed requirement)
• Compatible Shell Size: E (fixed requirement)
• Compatible D-Sub Size: 9pos and HD15pos (fixed requirement)
• Cable Exit Angle: 180° (fixed requirement)
• Accessory Type: Two Piece Backshell (fixed requirement)
• Hardware Configuration: Assembly Hardware, Cable Clamp with Mating Screws 4-40 (fixed requirement)

Parameters that may vary between the main part and acceptable substitutes:

• Shielding: Shielded or Unshielded (application-dependent)
• Material Composition: ABS Metallized or Thermoplastic (performance-dependent)
• Color: May differ based on application requirements
• Plating: May vary based on environmental specifications

The substitute part 61800925322 maintains all fixed parameters while differing in shielding specification (Unshielded vs. Shielded) and material composition (Thermoplastic vs. ABS Metallized).

Parameter Comparison

Engineering Selection Recommendations

Both the 61800925311 and 61800925322 are active production parts manufactured by Würth Elektronik and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific electromagnetic interference (EMI) requirements:

• 61800925311 is specified for applications requiring shielded backshell construction with ABS metallized material composition.
• 61800925322 is specified for applications where unshielded construction is acceptable or preferred, utilizing thermoplastic material.

Both parts share identical mechanical compatibility with 9-position and HD15-position D-Sub connectors, identical cable exit geometry (180°), and identical hardware specifications (4-40 mating screws). The MSL rating of 1 (Unlimited) indicates both parts are suitable for unrestricted storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can 61800925322 be used as a direct replacement for 61800925311?

A: Direct replacement is possible only if the application does not require shielded backshell construction. The 61800925322 is unshielded, whereas the 61800925311 is shielded. All other mechanical and electrical parameters remain identical.

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

A: Shielding in D-Sub backshells provides electromagnetic interference (EMI) attenuation. The 61800925311 with shielding is specified for EMI-sensitive applications. The 61800925322 without shielding is suitable for applications where EMI protection is not required.

Q: Are both parts compatible with the same connector shells?

A: Yes. Both parts are compatible with shell size E and support 9-position and HD15-position D-Sub connectors. Cable exit angle (180°) and hardware specifications (4-40 mating screws) are identical.

Q: What material differences exist between these parts?

A: The 61800925311 uses ABS plastic with metallization, while the 61800925322 uses thermoplastic material. Material selection may affect mechanical durability and environmental resistance depending on application conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both 61800925311 and 61800925322 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What does MSL rating 1 mean for these parts?

A: MSL (Moisture Sensitivity Level) rating 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling.
