Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386C-1-102 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are: 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 substitute parts meet these criteria:

1. 3386C-1-102LF (Bourns Inc.) - Direct manufacturer variant with identical electrical and mechanical specifications. Differs in RoHS compliance status and packaging configuration.

2. 72XR1KLF (TT Electronics/BI) - Alternative manufacturer part with equivalent electrical performance and mechanical compatibility. Differs in series designation, packaging format, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

3386C-1-102LF is the primary direct substitute. It maintains identical electrical and mechanical specifications while offering improved compliance status. This part is ROHS3 compliant and REACH unaffected, addressing regulatory requirements that may apply to new designs or applications subject to environmental directives.

72XR1KLF is a cross-manufacturer alternative from TT Electronics/BI. It provides equivalent functional performance and meets the same compliance standards as the 3386C-1-102LF. Selection between Bourns and TT Electronics variants depends on supply chain considerations, procurement agreements, and design qualification requirements specific to the application.

Both substitute parts are active products with confirmed inventory availability and maintain full electrical and mechanical compatibility with the original 3386C-1-102 specification.

Frequently Asked Questions (FAQ)

Q: Can 3386C-1-102LF be used as a direct replacement for 3386C-1-102?

A: Yes. Both parts share identical electrical specifications (1 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient), mechanical configuration (through-hole PC pins, side adjustment, cermet material), and physical dimensions (0.375" x 0.375" square face). The primary difference is compliance certification status.

Q: What is the difference between 3386C-1-102 and 3386C-1-102LF?

A: The 3386C-1-102LF is ROHS3 compliant and REACH unaffected, whereas the 3386C-1-102 is RoHS non-compliant and REACH affected. Electrical and mechanical parameters are identical. The "LF" designation typically indicates lead-free termination processing.

Q: Is 72XR1KLF compatible with designs using 3386C-1-102?

A: Yes. The 72XR1KLF maintains all critical electrical parameters (1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical compatibility (through-hole mounting, PC pins, side adjustment, cermet material, identical physical dimensions). It is manufactured by TT Electronics/BI and meets ROHS3 and REACH compliance requirements.

Q: What packaging differences exist between these parts?

A: The 3386C-1-102 and 3386C-1-102LF are supplied in tube packaging. The 72XR1KLF is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Are there any compliance considerations when selecting a substitute?

A: The 3386C-1-102 is RoHS non-compliant and REACH affected. Both substitute parts (3386C-1-102LF and 72XR1KLF) are ROHS3 compliant and REACH unaffected. Applications subject to RoHS or REACH regulations should use one of the compliant substitute parts.
