Key Parameters

Substitute Part Grouping Explanation

The 3006P-1-102 from Bourns Inc. is identified as a substitute based on the following compatibility criteria:

Key Substitution Parameters:

• Resistance Value: 1 kOhms (matches the "1K" designation in 343P1K)
• Power Rating: 0.75W (3/4W) - suitable for potentiometer applications
• Mounting Type: Through Hole (standard for potentiometer replacement)
• Termination Style: PC Pins (compatible with legacy circuit board designs)
• Adjustment Type: Side Adjustment (standard potentiometer configuration)
• Resistive Material: Cermet (durable material for sensor applications)

The substitute maintains electrical performance characteristics within standard potentiometer operating ranges and provides mechanical compatibility for direct replacement in through-hole applications.

Engineering Selection Recommendations

The Bourns 3006P-1-102 is an active product with current manufacturing and supply availability, addressing the obsolescence of the Honeywell 343P1K. Selection of this substitute should account for the following:

• The substitute carries EAR99 ECCN classification, suitable for general commercial applications
• RoHS non-compliance status of the 3006P-1-102 should be evaluated against system-level compliance requirements
• REACH Affected status indicates regulatory applicability in EU markets
• Through-hole PC pin termination provides direct mechanical compatibility with legacy circuit board layouts
• The 15-turn configuration and side adjustment mechanism support precision potentiometer applications

Frequently Asked Questions (FAQ)

Q: Can the 3006P-1-102 directly replace the 343P1K in existing assemblies?

A: Direct mechanical and electrical replacement is supported for through-hole applications. Physical dimensions (0.250" x 0.190" face) and PC pin termination are compatible with standard potentiometer footprints. Functional verification is required for specific circuit implementations.

Q: What are the key electrical parameters for substitution compatibility?

A: The 1 kOhms resistance value, 0.75W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient define the electrical substitution basis. These parameters ensure functional equivalence in potentiometer sensor applications.

Q: Are there compliance considerations when substituting the 343P1K?

A: The 3006P-1-102 is RoHS non-compliant and REACH Affected. Systems requiring RoHS compliance or operating in REACH-regulated markets must evaluate regulatory impact before substitution.

Q: What is the packaging format for the substitute part?

A: The 3006P-1-102 is supplied in Tube packaging, standard for through-hole component distribution.

Q: How does the 15-turn adjustment specification affect application suitability?

A: The 15-turn configuration provides fine adjustment resolution typical for precision potentiometer applications. This specification should be cross-referenced with original circuit design requirements for adjustment range and resolution.
