91601-407ALF Equivalent & Substitute Parts

Part Overview

The 91601-407ALF is a 7-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) from the Dubox™ series. This surface mount, board-to-board connector features a 0.100" (2.54mm) pitch and tin contact finish. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91601-407ALF is determined by strict adherence to the following critical parameters:

• Connector Type & Position Count: Must be a 7-position receptacle, bottom or top entry configuration
• Pitch Specification: Mating pitch must be 0.100" (2.54mm)
• Mounting & Termination: Surface mount with solder termination required
• Board-to-Board Style: Connector style must remain board-to-board
• Fastening Mechanism: Push-pull fastening type must be maintained
• Mechanical Dimensions: Mated stacking height of 10.81mm and insulation height of 0.275" (6.99mm) must be preserved
• Material & Compliance: Thermoplastic, glass-filled insulation with UL94 V-0 flammability rating required

The 91601-307ALF qualifies as a direct substitute based on these parameters. Variations in contact finish material (tin versus gold) and contact finish thickness do not affect mechanical or electrical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 91601-307ALF is the qualified substitute for the obsolete 91601-407ALF. Selection should be based on the following factors:

Product Status: The 91601-407ALF is obsolete, while the 91601-307ALF maintains active product status with current manufacturing support and availability.

Compliance & Certifications: Both parts meet UL94 V-0 flammability requirements and share identical ECCN (EAR99) and HTSUS classifications. The 91601-307ALF carries RoHS Compliant certification, providing additional regulatory alignment for modern applications.

Mechanical & Electrical Compatibility: All critical parameters—connector type, position count, pitch, mounting method, fastening mechanism, and stacking height—are identical between the two parts, ensuring direct mechanical and electrical interchangeability.

Contact Finish Consideration: The primary difference is the mating contact finish. The 91601-407ALF uses tin (78.7µin / 2.00µm), while the 91601-307ALF uses gold (30.0µin / 0.76µm). Both finishes are suitable for the specified applications (Automotive, General Purpose, Industrial, Telecommunications) and do not affect connector functionality within the defined parameter set.

Availability: The 91601-307ALF is currently in stock with 848 pieces available, compared to the obsolete status of the main part.

Frequently Asked Questions (FAQ)

Q: Can the 91601-307ALF be used as a direct replacement for the 91601-407ALF?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, mounting method, termination, fastening type, insulation material, flammability rating, and mechanical dimensions. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the tin and gold contact finishes?

A: The 91601-407ALF features tin contact finish at 78.7µin (2.00µm) thickness, while the 91601-307ALF features gold contact finish at 30.0µin (0.76µm) thickness. Both finishes are suitable for the specified applications and do not affect connector performance within the defined parameter set.

Q: Why is the 91601-407ALF classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The 91601-307ALF, as an active product from the same Dubox™ series with identical mechanical and electrical specifications, provides continuity for designs requiring this connector type.

Q: Are there packaging differences between these parts?

A: The 91601-407ALF packaging is not specified in the available data. The 91601-307ALF is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components and supports automated assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: The 91601-307ALF is explicitly RoHS Compliant. RoHS status for the 91601-407ALF is not specified in the available data. For applications requiring RoHS compliance, the 91601-307ALF is the appropriate selection.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
