Substitute Part Grouping Explanation

The substitute part 87606-413LF is identified as a direct equivalent based on the following substitution criteria:

Shared Functional Parameters:

• Manufacturer: Amphenol ICC (FCI) — maintains design consistency and quality standards
• Socket/Receptacle Function: Both components serve as female contact receptacles for mating applications
• Contact Material & Finish: Both utilize phosphor bronze with metallic finish for reliable electrical conductivity
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited), indicating equivalent environmental stability
• Termination Compatibility: Crimp termination (76785-301) and solder termination (87606-413LF) both provide secure mechanical attachment

Substitution Logic: The 87606-413LF represents a connector receptacle solution within the Dubox™ series, offering active product status and RoHS compliance. While the original part operates in flat flexible connector applications, the substitute accommodates board-to-board connectivity with standardized 0.100" (2.54mm) pitch spacing, suitable for applications requiring receptacle socket functionality.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The 76785-301 is classified as obsolete and no longer in active production. The 87606-413LF is the designated substitute, offering active product status and current manufacturing support from Amphenol ICC (FCI).

Compliance Considerations: The 87606-413LF provides RoHS compliance, addressing regulatory requirements for new designs and systems subject to RoHS directives. The original 76785-301 is RoHS non-compliant and unsuitable for applications with RoHS mandates.

Environmental & Reliability: Both components maintain MSL 1 rating, indicating unlimited moisture sensitivity tolerance. The substitute's UL94 V-0 flammability rating provides documented fire safety performance for industrial and telecommunications applications.

Termination Method Transition: The original part utilizes crimp termination, while the substitute employs solder termination. System redesign may be required to accommodate this termination method change. The substitute's through-hole mounting type and push-pull fastening provide mechanical stability for board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the 87606-413LF directly replace the 76785-301 without circuit modification?

A: The 87606-413LF serves as a functional equivalent for receptacle socket applications. However, termination method differs (solder vs. crimp), requiring assembly process adjustment. Mechanical mounting and electrical interface compatibility must be verified for your specific application.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status ensures ongoing manufacturing, quality control, and technical support from Amphenol ICC (FCI). The 87606-413LF guarantees long-term availability and supply chain reliability, critical for production systems and future design iterations.

Q: How do the contact finish specifications compare?

A: The 76785-301 features gold plating at 29.5µin (0.75µm), while the 87606-413LF uses tin plating at 78.7µin (2.00µm). Gold provides superior corrosion resistance and lower contact resistance; tin offers cost efficiency and RoHS compliance. Selection depends on application requirements for signal integrity and environmental exposure.

Q: Is the 87606-413LF suitable for flat flexible connector applications?

A: The 87606-413LF is designed for board-to-board rectangular connector applications with 0.100" (2.54mm) pitch spacing. Applications originally using flat flexible connectors may require mechanical redesign to accommodate the substitute's form factor and mounting type.

Q: What certifications and standards apply to the substitute part?

A: The 87606-413LF meets RoHS compliance, UL94 V-0 flammability rating, and is classified under ECCN EAR99 with HTSUS code 8536.69.4040. These certifications support automotive, industrial, and telecommunications applications.
