Substitute Part Grouping Explanation

Substitution of the 75853-411 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 21-position receptacle with 3-row arrangement
• Contact Pitch: 0.100" (2.54mm) spacing
• Mounting Style: Free-hanging (in-line) orientation
• Termination Method: IDC (Insulation Displacement Contact)
• Contact Material: Gold plating
• Current Capacity: 1.5A per contact minimum
• Flammability Compliance: UL94 V-0 rating
• Temperature Operating Range: Minimum -40°C to 125°C (note: original part specifies -55°C to 125°C)

The substitute part BPS8B21FLD200L9LF meets all critical electrical and mechanical parameters required for direct substitution in backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

The BPS8B21FLD200L9LF is the manufacturer-recommended substitute for the obsolete 75853-411. Both connectors are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active Product Status: The BPS8B21FLD200L9LF is currently in active production, ensuring long-term availability and supply chain stability.
• RoHS Compliance: The substitute meets RoHS requirements, supporting compliance with current environmental regulations.
• Equivalent Performance: All functional parameters—connector configuration, pitch, termination method, contact rating, and flammability rating—are identical to the original part.

The operating temperature range of the substitute (-40°C to 125°C) covers the upper operating limit of the original part. Applications requiring the full -55°C lower temperature specification should be evaluated against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the BPS8B21FLD200L9LF be used as a direct replacement for the 75853-411?

A: Yes. Both connectors share identical electrical and mechanical specifications: 21-position receptacle, 0.100" pitch, 3-row configuration, free-hanging mounting, IDC termination, gold contacts, 1.5A current rating, and UL94 V-0 flammability rating. The substitute is the manufacturer-recommended equivalent.

Q: What is the difference in operating temperature range?

A: The original 75853-411 operates from -55°C to 125°C. The substitute BPS8B21FLD200L9LF operates from -40°C to 125°C. The substitute covers the upper temperature limit. Applications requiring operation below -40°C should be evaluated against specific system requirements.

Q: Does the substitute part have different packaging?

A: The 75853-411 packaging is not specified in the original documentation. The BPS8B21FLD200L9LF is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the RoHS compliance difference?

A: The 75853-411 is RoHS non-compliant. The BPS8B21FLD200L9LF is RoHS compliant. If your application or regulatory environment requires RoHS compliance, the substitute part satisfies this requirement.

Q: Are there any compatibility concerns with existing designs?

A: No compatibility concerns exist. The substitute maintains identical connector geometry, contact pitch, mounting style, and electrical characteristics. Existing PCB layouts, mating connectors, and cable assemblies designed for the 75853-411 are compatible with the BPS8B21FLD200L9LF.

Q: What is the current inventory status?

A: The 75853-411 has 728 pieces in stock (obsolete status). The BPS8B21FLD200L9LF has 693 pieces in stock (active status). For new designs or long-term production, the active substitute part is recommended.
