Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 34FL2-113 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 20k Ohm (exact match required)
• Tolerance: ±10% (matching specification)
• Taper characteristic: Linear (functional requirement)
• Number of gangs: 2 (dual-channel configuration)
• Number of turns: 1 (single-turn operation)

Mechanical Compatibility Requirements:

• Mounting type: Servo Mount (mechanical interface)
• Termination style: Solder Turret (connection method)
• Actuator type and dimensions: Slotted, 0.625" length, 0.1248" diameter
• Body size: Round, 0.750" diameter

Performance Characteristics:

• Power rating: 0.01W minimum
• Temperature coefficient: ±500ppm/°C or better

The Bourns PTD902-1015P-B203 shares the core electrical specifications (20k Ohm, ±10% tolerance, 2-gang linear configuration, 1-turn operation) but differs in mounting type (panel mount vs. servo mount), termination style (PC pins with board locks vs. solder turret), resistive material (carbon vs. conductive plastic), and rotation range (300° vs. continuous). These differences indicate the PTD902-1015P-B203 functions as an electrical equivalent for resistance and taper characteristics but requires mechanical interface redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Honeywell 34FL2-113 is classified as obsolete. The Bourns PTD902-1015P-B203 is active production status, ensuring long-term availability and supply chain continuity.

Compliance Status: Both components meet RoHS compliance requirements. The Honeywell 34FL2-113 is RoHS Compliant; the Bourns PTD902-1015P-B203 is ROHS3 Compliant. Both components carry ECCN EAR99 classification and identical HTSUS codes (8533.40.8070), indicating equivalent regulatory treatment.

Electrical Equivalence: The PTD902-1015P-B203 provides electrical equivalence for the core 20k Ohm, 2-gang linear potentiometer function. The power rating of 0.05W exceeds the 0.01W requirement, providing operational margin. Both components maintain ±10% tolerance and linear taper characteristics.

Mechanical Considerations: Direct mechanical substitution is not feasible without circuit board redesign. The servo mount interface of the 34FL2-113 differs from the panel mount configuration of the PTD902-1015P-B203. Solder turret termination differs from PC pin termination with board locks. Rotation characteristics differ (continuous vs. 300°). These differences require evaluation against specific application mechanical constraints.

Material Difference: The resistive material differs (conductive plastic vs. carbon). This distinction affects noise characteristics, frequency response, and environmental performance. Application-specific requirements must determine acceptability of this substitution.

Frequently Asked Questions (FAQ)

Q: Can the Bourns PTD902-1015P-B203 directly replace the Honeywell 34FL2-113 in existing designs?

A: Electrical substitution is feasible for the 20k Ohm, 2-gang linear potentiometer function. Mechanical substitution requires circuit board redesign due to differences in mounting type (servo mount vs. panel mount), termination style (solder turret vs. PC pins with board locks), and rotation range (continuous vs. 300°).

Q: What are the critical parameters that must match for substitution?

A: Resistance value (20k Ohm), tolerance (±10%), taper (linear), number of gangs (2), and number of turns (1) are the critical electrical parameters. Mounting type, termination style, and rotation characteristics are critical mechanical parameters that determine direct substitution feasibility.

Q: Does the higher power rating of the PTD902-1015P-B203 (0.05W vs. 0.01W) affect compatibility?

A: The higher power rating of the substitute part does not create incompatibility. The 0.05W rating provides operational margin and indicates the component can safely handle the 0.01W requirement of the original application.

Q: Are there compliance or regulatory differences between these components?

A: Both components are RoHS compliant and carry identical ECCN and HTSUS classifications. The Honeywell part is RoHS Compliant; the Bourns part is ROHS3 Compliant. Both meet current regulatory requirements for equivalent treatment.

Q: What is the significance of the resistive material difference (conductive plastic vs. carbon)?

A: Conductive plastic and carbon resistive materials exhibit different noise characteristics, frequency response, and environmental performance. The material difference must be evaluated against specific application requirements for noise, temperature stability, and frequency response performance.

Q: What packaging differences exist between these components?

A: The Honeywell 34FL2-113 is supplied in standard packaging (not specified in provided data). The Bourns PTD902-1015P-B203 is supplied in tray packaging. Packaging differences affect handling, storage, and integration into assembly processes.

Q: Is the 300° rotation limit of the PTD902-1015P-B203 compatible with applications requiring continuous rotation?

A: The rotation characteristic difference (continuous vs. 300°) represents a functional limitation. Applications requiring continuous rotation operation cannot use the PTD902-1015P-B203 without mechanical redesign or alternative component selection.
