FOD4216V Equivalent & Substitute Parts

Part Overview

The FOD4216V is an optoisolator with triac output manufactured by onsemi, designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This component features a single-channel triac output in a 6-DIP through-hole package and maintains active product status with full regulatory compliance. Substitute parts are identified when equivalent electrical and mechanical specifications align with the main part's functional requirements, enabling seamless integration in circuit designs where component availability or packaging preferences necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FOD4216V is determined by strict equivalence across the following critical parameters: output type (triac), isolation voltage rating (5000Vrms), off-state voltage (600V), static dV/dt rating (10kV/µs), number of channels (1), package type (6-DIP through-hole), operating temperature range (-55°C ~ 100°C), and regulatory compliance certifications. The FOD420 qualifies as a substitute part because it maintains identical specifications across all these core parameters. Variations in secondary parameters such as LED trigger current (Ift) and packaging format (bulk versus tube) do not disqualify substitution when the primary electrical and mechanical characteristics remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both FOD4216V and FOD420 maintain active product status and ROHS3 compliance. The FOD4216V carries additional VDE certification beyond the FOD420's cUL, FIMKO, and UL approvals. Selection between these parts should be based on specific regulatory requirements for the end application. The FOD420 presents a higher LED trigger current specification (2mA maximum versus 1.3mA), which may require circuit design consideration in applications with strict input current budgets. Packaging format differences (bulk versus tube) reflect supply chain and assembly process preferences rather than functional incompatibility. Both parts are electrically and mechanically interchangeable for applications requiring 5000Vrms triac-output optoisolation in 6-DIP through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can FOD420 replace FOD4216V in existing designs? A: Yes. Both parts share identical core electrical specifications including isolation voltage, off-state voltage, dV/dt rating, hold current, turn-on time, forward voltage, and forward current. The 6-DIP through-hole package and operating temperature range are equivalent. Pin-for-pin substitution is supported.

Q: What is the significance of the LED trigger current difference? A: FOD4216V specifies a maximum LED trigger current (Ift) of 1.3mA, while FOD420 specifies 2mA. This difference affects the input circuit design. Applications requiring lower input current should verify that the FOD420's higher trigger current remains within acceptable limits for the driving circuit.

Q: Does packaging format affect electrical performance? A: No. Bulk and tube packaging formats are supply and assembly logistics distinctions only. Electrical and mechanical performance remain identical. Selection depends on manufacturing process requirements and component handling procedures.

Q: Are regulatory certifications equivalent? A: FOD4216V holds cUL, FIMKO, UL, and VDE certifications. FOD420 holds cUL, FIMKO, and UL certifications. Applications requiring VDE compliance must use FOD4216V. For applications requiring only cUL, FIMKO, or UL compliance, both parts are acceptable.

Q: What determines substitution eligibility? A: Substitution is based on matching isolation voltage (5000Vrms), off-state voltage (600V), static dV/dt (10kV/µs), output type (triac), channel count (1), package type (6-DIP), mounting method (through-hole), and operating temperature range (-55°C ~ 100°C). All these parameters are identical between FOD4216V and FOD420.
