Parameter Comparison

Engineering Selection Recommendations

The DKLP-0331-0430 is the recommended substitute for the obsolete DKLL-0331-0430. Both parts maintain identical electrical performance specifications, mechanical dimensions, and regulatory compliance certifications. The primary distinction is product status: DKLP-0331-0430 is active and currently available in inventory (1173 pcs), while DKLL-0331-0430 is obsolete with limited remaining stock (1129 pcs). For new designs and ongoing procurement, DKLP-0331-0430 provides continuity of supply and long-term availability assurance while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can DKLP-0331-0430 be used as a direct replacement for DKLL-0331-0430?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (4A, 155mOhm DCR, 760V DC, 540V AC), operating temperature range (-25°C ~ 100°C), physical dimensions (80mm x 80mm), mounting type (through hole), and regulatory certifications (UR approval, ROHS3 compliant).

Q: What is the primary reason to substitute DKLL-0331-0430?

A: DKLL-0331-0430 is classified as obsolete. DKLP-0331-0430 is an active product with current manufacturing and inventory availability, ensuring long-term supply chain continuity.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts share identical physical dimensions (3.150" L x 3.150" W / 80.00mm x 80.00mm), nonstandard package configuration, and through-hole mounting type. PCB layout and mechanical integration remain unchanged.

Q: Do compliance certifications differ between the two parts?

A: No. Both DKLL-0331-0430 and DKLP-0331-0430 carry identical compliance status: UR approval, ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification.

Q: What inventory status should influence procurement decisions?

A: DKLP-0331-0430 (active, 1173 pcs available) is preferred over DKLL-0331-0430 (obsolete, 1129 pcs remaining) for new procurement and design continuity.
