S4016RTP Equivalent & Substitute Parts

Part Overview

The S4016RTP is a 400V 16A Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. in TO-220-3 through-hole packaging. This thyristor operates as a standard recovery device with an off-state voltage rating of 400V and RMS on-state current capability of 16A. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating application requirements for voltage rating, current capacity, or packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S4016RTP is determined by the following critical parameters:

Primary Substitution Criteria:

• Off-state voltage rating must equal or exceed 400V
• RMS on-state current (It RMS) must equal or exceed 16A
• Gate trigger voltage (Vgt) and current (Igt) must remain within specified maximums
• SCR type must be Standard Recovery
• Operating temperature range must encompass -40°C to 125°C
• Mounting type must be Through Hole
• Package must be TO-220-3 compatible

Identified Substitute Parts:

Group 1 - Direct Voltage/Current Upgrade (Littelfuse 2N6507 Series):

• 2N6507G and 2N6507TG maintain 400V off-state voltage with increased RMS current capacity to 25A, exceeding the 16A requirement. Gate trigger parameters remain identical. Packaging is TO-220AB variant (compatible with TO-220-3 footprint). Both parts are active production status with ROHS3 compliance.

Group 2 - Voltage Upgrade (STMicroelectronics TYN616RG):

• TYN616RG provides 600V off-state voltage with matching 16A RMS current capacity. Gate trigger voltage remains at 1.5V maximum with slightly lower gate trigger current (25mA vs. 30mA). On-state voltage is equivalent at 1.6V maximum. Packaging is TO-220 variant (compatible with TO-220-3 footprint). Active production status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

2N6507G and 2N6507TG Selection: These Littelfuse parts are suitable substitutes when the application can accommodate increased on-state voltage (1.8V vs. 1.6V) and higher RMS current capacity (25A vs. 16A). Both parts maintain identical off-state voltage (400V) and gate trigger specifications. Selection between 2N6507G and 2N6507TG depends on packaging preference (Box vs. Tube) and inventory availability. Both are active production status with ROHS3 compliance and REACH unaffected designation.

TYN616RG Selection: This STMicroelectronics part is suitable when higher off-state voltage (600V) is required or beneficial for circuit margin. The part maintains identical RMS current capacity (16A) and on-state voltage (1.6V) as the S4016RTP. Gate trigger current is slightly lower (25mA vs. 30mA), which may improve gate drive efficiency. Active production status with ROHS3 compliance and REACH unaffected designation.

All substitute parts are active production components with equivalent compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN classification, and 8541.30.0080 HTSUS code).

Frequently Asked Questions (FAQ)

Q: Can 2N6507G or 2N6507TG be used as direct replacements for S4016RTP?

A: Yes, with circuit design consideration. Both parts meet or exceed all critical electrical parameters. The increased on-state voltage (1.8V vs. 1.6V) results in approximately 12.5% higher forward voltage drop. Verify that circuit design accommodates this voltage increase and the higher RMS current rating (25A vs. 16A) does not affect thermal management or component selection.

Q: What is the difference between 2N6507G and 2N6507TG?

A: Both parts are electrically identical with matching electrical specifications. The difference is packaging: 2N6507G is supplied in Box packaging while 2N6507TG is supplied in Tube packaging. Selection depends on assembly process requirements and inventory management preferences.

Q: Can TYN616RG replace S4016RTP in all applications?

A: TYN616RG is suitable for applications where the higher off-state voltage rating (600V vs. 400V) is acceptable or beneficial. The part maintains identical RMS current (16A) and on-state voltage (1.6V). Gate trigger current is slightly lower (25mA vs. 30mA). Verify that the higher voltage rating does not introduce unintended circuit behavior or cost implications.

Q: Are all substitute parts available in the same TO-220 package?

A: Yes. S4016RTP uses TO-220-3 Non-Isolated Tab packaging. 2N6507G and 2N6507TG use TO-220AB packaging, and TYN616RG uses TO-220 packaging. All three package variants are mechanically and electrically compatible with TO-220-3 footprints in standard through-hole PCB designs.

Q: Do all parts meet the same compliance requirements?

A: Yes. S4016RTP and all substitute parts (2N6507G, 2N6507TG, TYN616RG) are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and share the same HTSUS code (8541.30.0080). All parts have MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the primary reason to substitute S4016RTP?

A: Substitution is necessary when the original part is unavailable or when application requirements change. 2N6507 series parts provide higher current capacity (25A) for applications requiring increased thermal margin or higher load current. TYN616RG provides higher voltage rating (600V) for applications requiring increased voltage margin or operating in higher voltage circuits.
