Equivalent & Substitute Parts for 3314Z-1-102G

Part Overview

The Bourns 3314Z-1-102G is a 1 kOhm, 0.25W surface mount trimmer potentiometer with side adjustment, designed for precision circuit tuning applications. This component features a cermet resistive element, J lead termination, and is rated for 1.0 turn adjustment. The part is currently active in production and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3314Z-1-102G are qualified based on the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1.0 (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Surface Mount (exact match required)
• Termination style: J Lead (exact match required)
• Packaging: Tape & Reel (exact match required)

All identified substitutes meet these core electrical and mechanical criteria. Differences in adjustment type (side vs. top) and physical dimensions represent design variations that may affect PCB layout and assembly procedures but do not alter the functional electrical performance of the trimmer potentiometer.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet the core electrical specifications of the 3314Z-1-102G. Selection between these alternatives should be based on the following considerations:

23AR1KLFTR and ST-4ETA102 are functionally equivalent with identical face dimensions (5.00mm x 4.50mm) and top adjustment configuration. Both maintain MSL 1 rating, providing equivalent moisture handling characteristics to the original part. ST-4ETA102 carries ROHS3 certification matching the primary part.

TS53YJ102MR10 provides electrical equivalence with a square face dimension (5.00mm x 5.00mm) and top adjustment. This part carries MSL 4 rating, requiring controlled storage conditions (72-hour maximum exposure to ambient conditions above 30°C and 60% relative humidity) prior to soldering. This moisture sensitivity difference may impact supply chain handling and assembly scheduling.

The primary distinction between the 3314Z-1-102G and all substitutes is adjustment orientation: side adjustment versus top adjustment. This affects PCB layout accessibility and tuning procedure methodology but does not alter electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 3314Z-1-102G be directly replaced with 23AR1KLFTR on an existing PCB?

A: Electrical substitution is valid. However, the adjustment type differs (side vs. top), and the face dimensions are smaller (5.00mm x 4.50mm vs. 5.56mm x 5.01mm). PCB layout modification may be required to accommodate the different adjustment access point and physical footprint.

Q: What is the impact of MSL 4 rating on TS53YJ102MR10 compared to MSL 1 parts?

A: MSL 4 designation requires that the component be stored in controlled humidity conditions and soldered within 72 hours of exposure to ambient conditions exceeding 30°C and 60% relative humidity. MSL 1 parts have unlimited shelf life under standard conditions. This affects inventory management and assembly scheduling but does not impact electrical performance after soldering.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All identified substitutes are supplied in Tape & Reel (TR) packaging, matching the original part's packaging format for automated assembly compatibility.

Q: Do all substitutes meet RoHS compliance requirements?

A: All substitutes are RoHS compliant. The 3314Z-1-102G, ST-4ETA102, and TS53YJ102MR10 carry ROHS3 certification. The 23AR1KLFTR carries RoHS compliance designation. Both certifications satisfy RoHS Directive requirements.

Q: What are the inventory levels for each substitute?

A: Current stock levels are 855 pcs for 3314Z-1-102G, 10703 pcs for 23AR1KLFTR, 11333 pcs for ST-4ETA102, and 1762 pcs for TS53YJ102MR10.
