1N4110-TP Zener Diode Equivalent & Substitute Parts

Part Overview

The 1N4110-TP is a 16 V, 500 mW Zener diode manufactured by Micro Commercial Co in a DO-35 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and production continuity. Substitute parts must maintain electrical compatibility across voltage regulation, power dissipation, and forward conduction characteristics while accommodating available packaging and supplier options.

Substitute Part Grouping Explanation

Substitution eligibility for the 1N4110-TP is determined by the following critical parameters:

Primary Electrical Criteria:

Zener voltage: 16 V nominal
Power dissipation capability: minimum 500 mW
Voltage tolerance: ±5% or tighter
Forward voltage drop: 1.1 V maximum @ 200 mA
Reverse leakage current: compatible with circuit requirements

Mechanical Criteria:

Through-hole mounting configuration
DO-35 / DO-204AH package compatibility
Axial lead orientation

Compliance Criteria:

RoHS3 compliance required for new designs
Moisture sensitivity level 1 (unlimited)

Parts meeting these criteria are classified as direct substitutes. Parts with reduced power ratings (250 mW) or relaxed voltage tolerance (±10%) are classified as similar substitutes with application-dependent suitability.

Engineering Selection Recommendations

Direct Substitutes (Preferred):

The 1N5246B-TAP and 1N5246B-TR are direct electrical and mechanical equivalents to the 1N4110-TP. Both parts are manufactured by Vishay General Semiconductor and maintain identical zener voltage (16 V), power rating (500 mW), voltage tolerance (±5%), and forward voltage characteristics. Both are RoHS3 compliant and available in active production status.

The 1N5246B-TAP is qualified to AEC-Q101 automotive standards and supplied in cut tape packaging. The 1N5246B-TR is supplied in cut tape packaging without automotive qualification. Selection between these two depends on application requirements and procurement specifications.

Similar Substitute (Application-Dependent):

The 1N719 manufactured by Microchip Technology maintains the 16 V zener voltage and through-hole DO-35 package configuration. However, this part has a reduced maximum power rating of 250 mW (compared to 500 mW) and a relaxed voltage tolerance of ±10% (compared to ±5%). The 1N719 is RoHS non-compliant, which restricts its use in applications subject to RoHS3 requirements.

The 1N719 is suitable only for applications where the 250 mW power dissipation is sufficient and ±10% voltage tolerance is acceptable. This part is not recommended for new designs requiring RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 1N5246B-TAP and 1N5246B-TR be used interchangeably with the 1N4110-TP?

A: Yes. Both Vishay parts are direct substitutes with identical electrical specifications (16 V, 500 mW, ±5% tolerance) and compatible DO-35 through-hole packaging. The primary difference is packaging format: 1N5246B-TAP is supplied in cut tape, while 1N5246B-TR is also supplied in cut tape. Selection depends on procurement and assembly requirements.

Q: What is the difference between the 1N5246B-TAP and 1N5246B-TR?

A: Both parts are electrically identical. The 1N5246B-TAP includes AEC-Q101 automotive qualification, while the 1N5246B-TR does not. For automotive applications, the 1N5246B-TAP is the appropriate selection. For non-automotive applications, either part is acceptable.

Q: Can the 1N719 replace the 1N4110-TP?

A: The 1N719 is a partial substitute with limitations. It maintains the 16 V zener voltage and DO-35 package but has a reduced power rating (250 mW versus 500 mW) and relaxed tolerance (±10% versus ±5%). The 1N719 is also RoHS non-compliant. Use the 1N719 only in applications where 250 mW power dissipation is sufficient, ±10% voltage tolerance is acceptable, and RoHS3 compliance is not required.

Q: Why is the 1N4110-TP obsolete?

A: The 1N4110-TP is classified as obsolete by the original manufacturer. Active equivalent parts from other manufacturers (Vishay and Microchip) are available to support ongoing production and design requirements.

Q: Are all substitute parts RoHS3 compliant?

A: The 1N5246B-TAP and 1N5246B-TR are RoHS3 compliant. The 1N719 is RoHS non-compliant. For applications requiring RoHS3 compliance, use only the Vishay parts.

Q: What is the impedance difference between the main part and substitutes?

A: The 1N4110-TP has a maximum impedance of 100 Ohms, while the 1N5246B-TAP, 1N5246B-TR, and 1N719 have lower impedance values (17, 17, and 15 Ohms respectively). Lower impedance provides improved voltage regulation characteristics and is generally favorable for circuit performance.

Q: Are the substitute parts available in the same packaging as the original?

A: All substitute parts are available in DO-35 through-hole axial packages compatible with the original 1N4110-TP. Packaging format options differ: the Vishay parts are supplied in cut tape, while the Microchip part is supplied in bulk.
