PW602J2 Equivalent & Substitute Parts

Part Overview

The PW602J2 is an NTC thermistor manufactured by Littelfuse Inc., designed as a 6kΩ bead-type temperature sensor with epoxy packaging. This component is classified as obsolete, making equivalent substitutes necessary for ongoing applications and new designs. The part operates at a maximum temperature of 120°C with a power rating of 30 mW and features free-hanging mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PW602J2 is based on the following critical parameters:

• Resistance Value: 6kΩ at 25°C (primary electrical characteristic)
• Thermistor Type: NTC (Negative Temperature Coefficient)
• Package Type: Bead configuration
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status
• Operating Temperature Range: Must accommodate the original 120°C maximum
• Power Dissipation: Substitute must support thermal management requirements

The substitute part 01C6001JF meets these criteria as an active NTC thermistor with matching 6kΩ resistance, bead package type, and superior operating temperature range (−40°C to 125°C), ensuring compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 01C6001JF serves as a direct functional equivalent to the obsolete PW602J2. Both components share identical 6kΩ resistance specifications and NTC thermistor classification, meeting the core electrical requirements for temperature sensing applications.

The substitute part offers enhanced specifications: an extended operating temperature range (−40°C to 125°C versus 120°C), increased power dissipation capability (100 mW versus 30 mW), and active product status ensuring long-term availability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The transition from free-hanging to through-hole mounting requires mechanical design consideration but does not affect electrical performance. The substitute's superior thermal characteristics provide additional design margin for temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the 01C6001JF directly replace the PW602J2 in existing designs?

A: Electrical substitution is valid based on matching 6kΩ resistance and NTC thermistor type. Mechanical integration requires evaluation of the mounting transition from free-hanging to through-hole configuration.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), operating temperature range (120°C versus −40°C to 125°C), power rating (30 mW versus 100 mW), and mounting type (free-hanging versus through-hole). Electrical characteristics remain equivalent.

Q: Are both parts regulatory compliant?

A: Yes. Both the PW602J2 and 01C6001JF are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Does the higher power rating of the substitute affect circuit design?

A: The 01C6001JF's 100 mW rating provides additional thermal dissipation capability compared to the original 30 mW specification. This represents an improvement that does not require circuit modification.

Q: What should be verified before implementation?

A: Confirm mechanical compatibility with the through-hole mounting requirement and validate thermal response characteristics within the specific application's temperature measurement range.
