Engineering Selection Recommendations

P1330R-474K as Direct Substitute:

The P1330R-474K is electrically and mechanically equivalent to the P1330-474K across all specified operational parameters. Both components are manufactured by API Delevan Inc. and share identical inductance, current ratings, DC resistance, core material, shielding configuration, temperature range, and physical dimensions.

The primary distinction between these parts is compliance certification status. The P1330R-474K carries ROHS3 compliance, while the P1330-474K is RoHS non-compliant. Both maintain REACH Unaffected status and identical moisture sensitivity levels.

Selection Criteria:

For RoHS-compliant applications: P1330R-474K is the appropriate selection
For non-compliant or legacy applications: P1330-474K remains valid
For inventory optimization: P1330R-474K offers higher stock availability (2425 pieces versus 777 pieces)

Both parts are active products with confirmed production status and are suitable for direct substitution in surface mount inductor applications requiring 470 µH inductance at 161 mA current rating.

Frequently Asked Questions (FAQ)

Q: Can P1330R-474K replace P1330-474K in all applications?

A: Yes. The P1330R-474K is electrically and mechanically identical to the P1330-474K. All electrical parameters, physical dimensions, and environmental ratings are equivalent. The only difference is RoHS compliance status.

Q: What is the significance of the "R" designation in P1330R-474K?

A: The "R" designation indicates ROHS3 compliance. This is a compliance marker and does not affect electrical or mechanical performance.

Q: Are the physical dimensions identical between P1330-474K and P1330R-474K?

A: Yes. Both components have identical dimensions: 0.313" L x 0.115" W (7.94mm x 2.92mm) with a maximum seated height of 0.145" (3.68mm). They are interchangeable in PCB layouts.

Q: What is the inductance tolerance for these parts?

A: Both parts have an inductance tolerance of ±10% at the 1 kHz test frequency.

Q: What is the maximum DC resistance specification?
