Engineering Selection Recommendations

For New Designs and RoHS-Compliant Applications:

Select from the ROHS3 compliant variants: 3386F-1-103LF, 3386G-1-103LF, 3386P-1-103LF, 3386P-EY5-103LF, or 3386R-1-103LF. These parts meet current regulatory requirements while maintaining full electrical and mechanical compatibility with the 363M10K specification.

For Maximum Availability:

The 3386P-1-103LF offers the highest inventory level (26,240 pcs) among all substitutes, combined with ROHS3 compliance and active product status. This part is the primary recommendation for procurement planning.

For Non-Compliant Legacy Applications:

If RoHS compliance is not required, the non-compliant variants (3386F-1-103, 3386G-1-103, 3386P-1-103, 3386R-1-103, 3386T-1-103) provide functional equivalence. All are active products with established supply chains.

For REACH-Unaffected Requirements:

Parts designated as REACH Unaffected include: 3386F-1-103LF, 3386G-1-103LF, 3386P-1-103LF, 3386P-EY5-103LF, and 3386R-1-103LF.

All substitute parts share identical electrical performance, mechanical dimensions, and mounting characteristics with the original 363M10K component.

Frequently Asked Questions (FAQ)

Q: Can I directly replace a Honeywell 363M10K with any of the listed Bourns 3386 series parts?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They feature identical resistance (10 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (top), resistive material (cermet), mounting method (through hole), termination style (PC pins), and physical dimensions (0.375" x 0.375" square face). Direct substitution is supported without circuit modification.

Q: What is the difference between 3386P-1-103 and 3386P-1-103LF?

A: Both parts are electrically and mechanically identical. The primary difference is RoHS compliance status: 3386P-1-103 is RoHS non-compliant, while 3386P-1-103LF is ROHS3 compliant. The "LF" designation indicates lead-free termination. For new designs, the LF variant is recommended.

Q: Why are there multiple 3386 series variants (F, G, P, R, T)?

A: These designations represent different sealed potentiometer configurations within the Bourns Trimpot 3386 family. All variants listed maintain the same electrical specifications and physical dimensions required for 363M10K substitution. The variant letter does not affect functional compatibility.

Q: Is the 363M10K still available for purchase?

A: The 363M10K is classified as obsolete. Current inventory is limited to 887 pcs. For new procurement, active substitute parts from the Bourns 3386 series are recommended, with 3386P-1-103LF offering the highest availability (26,240 pcs).

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected parts are subject to European chemical regulations and require compliance documentation. REACH Unaffected parts are not subject to these restrictions. For applications requiring REACH compliance, select from parts designated as REACH Unaffected: 3386F-1-103LF, 3386G-1-103LF, 3386P-1-103LF, 3386P-EY5-103LF, or 3386R-1-103LF.

Q: Can I use a non-compliant variant if my application does not require RoHS certification?

A: Yes. Non-compliant variants (3386F-1-103, 3386G-1-103, 3386P-1-103, 3386R-1-103, 3386T-1-103) are functionally equivalent and remain active products. Selection should be based on application requirements and regulatory environment.

Q: Are all substitute parts packaged identically?

A: All substitute parts are supplied in tube packaging. The 363M10K original packaging type is not specified in the provided data. Verify packaging requirements with your procurement department if specific packaging formats are required.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: The substitute parts list does not specify MSL values (listed as "Not Applicable"). The original 363M10K has MSL 1 (Unlimited). Confirm MSL requirements with the component manufacturer if moisture sensitivity is a design consideration.
