Amphenol ICC 91618-307 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91618-307 is a 14-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This surface mount connector features gold-plated mating contacts, push-pull fastening, and board lock functionality. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance posture.

Key Parameters

Substitute Part Grouping Explanation

The 91618-307LF qualifies as a direct substitute based on strict equivalence across all critical electrical and mechanical parameters. Substitution is determined by the following criteria:

• Identical connector type, position count, and pitch specifications
• Matching row configuration and spacing
• Equivalent contact material, finish type, and thickness specifications
• Identical mounting method and termination approach
• Same fastening mechanism and board lock features
• Matching insulation material and flammability rating
• Equivalent mated stacking height

The primary distinction between the main part and substitute is product status and RoHS compliance. The 91618-307 is obsolete and RoHS non-compliant, while the 91618-307LF is active and RoHS compliant. Both parts share the same base product number (91618) and are manufactured by Amphenol ICC within the Dubox™ series.

Parameter Comparison

Engineering Selection Recommendations

The 91618-307LF is the direct substitute for the obsolete 91618-307. Selection of the substitute is based on the following engineering factors:

Product Status: The 91618-307 is obsolete, creating supply chain risk and limiting availability for new production. The 91618-307LF maintains active product status with documented inventory availability.

Regulatory Compliance: The 91618-307LF is RoHS compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The original part is RoHS non-compliant, which may restrict its use in regulated applications.

Electrical and Mechanical Equivalence: All functional parameters are identical between the two parts. The connector maintains the same 14-position configuration, 0.100" pitch spacing, gold-plated mating contacts, and push-pull fastening mechanism. Surface mount termination and board lock features are preserved.

Packaging Consideration: The 91618-307LF is supplied in tube packaging, which is standard for production environments and does not affect functional compatibility.

For applications currently using the 91618-307, direct substitution with the 91618-307LF is appropriate without design modification or re-qualification, provided that RoHS compliance requirements are met or do not apply to the end application.

Frequently Asked Questions (FAQ)

Q: Are the 91618-307 and 91618-307LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch, row spacing, mating height, contact geometry, and mounting footprint. No PCB redesign is required for substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 91618-307 is obsolete and RoHS non-compliant. The 91618-307LF is an active product that meets RoHS requirements. All electrical and mechanical specifications are identical.

Q: Can I use the 91618-307LF as a replacement in existing designs?

A: Yes. The 91618-307LF is a direct functional equivalent. No design changes are necessary. Verify that RoHS compliance is acceptable for your application requirements.

Q: What does the "LF" suffix in 91618-307LF indicate?

A: The "LF" suffix typically indicates lead-free or RoHS-compliant processing. In this case, it denotes the RoHS-compliant version of the base connector.

Q: Are there any performance differences between the two parts?

A: No. Both parts are manufactured to identical specifications for electrical performance, contact resistance, and mechanical durability. The contact material, finish type, and thickness are equivalent.

Q: What is the packaging difference?

A: The 91618-307 packaging is not specified in the available data. The 91618-307LF is supplied in tube packaging, which is standard for production quantities and does not affect connector performance or compatibility.

Q: Is the 91618-307 still available for purchase?

A: The 91618-307 is listed as obsolete. Inventory may be available from legacy stock, but long-term availability is not assured. The 91618-307LF is the recommended active alternative with documented inventory.

Q: Do both connectors have the same moisture sensitivity level?

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