Substitute Part Grouping Explanation

Substitution eligibility for the 3262X-1-102 is determined by matching the following critical parameters: 1 kOhm resistance value, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, side adjustment mechanism, cermet resistive material, through-hole mounting, and PC pin termination. Parts meeting these electrical and mechanical specifications are classified as direct or similar substitutes based on dimensional compatibility and compliance status.

The 3262X-1-102LF qualifies as a direct manufacturer substitute, maintaining identical electrical specifications and the same Bourns Trimpot® 3262 series platform with improved RoHS3 compliance. The 64PR1KLF from TT Electronics/BI qualifies as a similar substitute, matching all electrical parameters and mechanical interface requirements, though with dimensional variation in the face geometry and different compliance certifications.

Engineering Selection Recommendations

The 3262X-1-102LF is the preferred direct substitute when RoHS3 compliance is required. Both parts are manufactured by Bourns and share identical electrical specifications, mechanical interface, and dimensional footprint. The 3262X-1-102LF maintains the same Trimpot® 3262 sealed series platform with enhanced regulatory compliance.

The 64PR1KLF from TT Electronics/BI is suitable as an alternative when cross-manufacturer sourcing is necessary or when REACH unaffected status is a requirement. This part matches all critical electrical parameters and mechanical interface specifications. The primary consideration is the dimensional difference in face geometry: the 64PR1KLF presents a square 0.250" x 0.250" face compared to the rectangular 0.250" x 0.170" face of the 3262X-1-102. This dimensional variation may affect mechanical fit in space-constrained applications or PCB layouts designed specifically for the rectangular profile.

Frequently Asked Questions (FAQ)

Q: Can the 3262X-1-102LF be used as a direct replacement for the 3262X-1-102?

A: Yes. The 3262X-1-102LF is a direct substitute manufactured by Bourns with identical electrical specifications, tolerance, temperature coefficient, number of turns, adjustment mechanism, resistive material, mounting type, termination style, and physical dimensions. The primary difference is improved RoHS3 compliance status.

Q: What is the key difference between the 3262X-1-102 and the 64PR1KLF?

A: Both parts share identical electrical specifications and mechanical interface requirements. The 64PR1KLF is manufactured by TT Electronics/BI and features a square face dimension of 0.250" x 0.250" compared to the rectangular 0.250" x 0.170" face of the 3262X-1-102. Additionally, the 64PR1KLF has REACH unaffected status and MSL rating of 1 (Unlimited), whereas the 3262X-1-102 is REACH affected with no MSL rating.

Q: Are there any mechanical compatibility concerns when substituting the 64PR1KLF?

A: The 64PR1KLF maintains the same PC pin termination, through-hole mounting type, and electrical interface. However, the square face geometry differs from the rectangular profile of the 3262X-1-102. PCB layouts or mechanical enclosures designed specifically for the rectangular 0.250" x 0.170" profile may require evaluation for the square 0.250" x 0.250" geometry.

Q: Which substitute part should be selected for new designs?

A: Selection depends on specific requirements. For Bourns platform continuity and identical dimensions, use the 3262X-1-102LF. For cross-manufacturer sourcing or REACH compliance requirements, the 64PR1KLF is suitable provided mechanical fit is confirmed for the square face geometry.

Q: What are the compliance differences among these three parts?

A: The 3262X-1-102 is RoHS non-compliant and REACH affected. The 3262X-1-102LF is ROHS3 compliant and REACH affected. The 64PR1KLF is RoHS compliant and REACH unaffected. Selection should align with applicable regulatory requirements for the end application.
