Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386X-1-102 is determined by matching the following critical parameters: resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical dimensions (0.375" x 0.375" square face).

Two equivalent parts meet these criteria:

1. 3386X-1-102LF (Bourns Inc.) — Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs in RoHS compliance status (ROHS3 compliant vs. non-compliant) and REACH classification (unaffected vs. affected).

2. 72XR1KLF (TT Electronics/BI) — Cross-manufacturer equivalent from the 72 series with matching electrical performance and physical form factor. Packaging differs (bulk vs. tube).

Parameter Comparison

Engineering Selection Recommendations

3386X-1-102LF is the primary direct equivalent when regulatory compliance is required. This part maintains identical electrical and mechanical specifications while achieving ROHS3 compliance and REACH unaffected status. It is packaged in tube format matching the original specification and carries higher inventory availability (1159 units).

72XR1KLF serves as a cross-manufacturer alternative when bulk packaging is acceptable or preferred for high-volume applications. This TT Electronics/BI component meets all electrical and mechanical requirements with ROHS3 compliance and REACH unaffected status. Inventory availability is highest at 2606 units.

Selection between these substitutes depends on compliance requirements, packaging format needs, and supply chain priorities. All three parts are active products with confirmed availability.

Frequently Asked Questions (FAQ)

Q: Can 3386X-1-102LF replace 3386X-1-102 in existing designs?

A: Yes. The 3386X-1-102LF is electrically and mechanically identical to the 3386X-1-102. The primary difference is regulatory compliance status (ROHS3 compliant and REACH unaffected versus non-compliant and affected). Both use identical tube packaging and PC pin termination.

Q: What is the difference between tube and bulk packaging?

A: Tube packaging (3386X-1-102 and 3386X-1-102LF) provides individual component protection in reeled format suitable for automated assembly. Bulk packaging (72XR1KLF) is supplied in loose quantity format, typically for manual assembly or high-volume operations where packaging efficiency is prioritized.

Q: Is 72XR1KLF mechanically compatible with the original design?

A: Yes. The 72XR1KLF maintains the same 0.375" x 0.375" square footprint, through-hole mounting configuration, and PC pin termination. Physical form factor compatibility is confirmed. Packaging format differs (bulk versus tube).

Q: Which substitute should be selected for new designs?

A: For new designs, 3386X-1-102LF is recommended as the primary choice due to ROHS3 compliance and REACH unaffected status, combined with tube packaging consistency. The 72XR1KLF is suitable when bulk packaging aligns with manufacturing processes.

Q: Are all three parts rated for the same operating conditions?

A: Yes. All three parts share identical electrical specifications: 1 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and 1-turn side adjustment. Operating temperature range and environmental performance are equivalent across all three options.
