Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KNP100JR-52-56R is determined by the following critical parameters:

• Resistance Value: Must be 56 Ohms
• Tolerance: Must be ±5%
• Composition: Must be Wirewound
• Package Type: Must be Axial
• Operating Temperature Range: Must support -40°C ~ 200°C
• Terminations: Must have 2 terminations
• Compliance: Must maintain ROHS3 and REACH compliance status

The identified substitute parts maintain these core electrical and mechanical specifications. Variations in power rating (1W vs. 3W) and physical dimensions are permitted when the application circuit design accommodates the substitute component's characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 and REACH compliance. Selection between the main part and substitutes depends on circuit design requirements:

PNP300JR-73-56R (Upgrade): Identical electrical specifications and physical dimensions to the main part, with increased power dissipation capability (3W vs. 1W). This part is suitable for applications requiring higher thermal margin or increased power handling without circuit board redesign.

KNP1WSJR-52-56R (MFR Recommended): Maintains the same 1W power rating and electrical specifications as the main part. Physical dimensions are reduced (0.138" Dia x 0.354" L vs. 0.181" Dia x 0.453" L). This part is suitable for space-constrained applications where the smaller form factor is compatible with circuit board layout.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-56R replace KNP100JR-52-56R in any application?

A: PNP300JR-73-56R maintains identical electrical specifications (56 Ohms, ±5%, wirewound composition) and physical dimensions. The 3W power rating provides additional thermal capacity. Substitution is valid when the circuit design accommodates the higher power rating specification.

Q: What is the difference between KNP1WSJR-52-56R and KNP100JR-52-56R?

A: Both parts are 56 Ohms ±5% 1W wirewound axial resistors with identical electrical specifications. KNP1WSJR-52-56R has a smaller physical form factor (0.138" Dia x 0.354" L vs. 0.181" Dia x 0.453" L). Substitution is valid when the reduced dimensions are compatible with circuit board layout and component placement.

Q: Are all three parts ROHS3 compliant?

A: Yes. KNP100JR-52-56R, PNP300JR-73-56R, and KNP1WSJR-52-56R are all ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available for these parts?

A: KNP100JR-52-56R is supplied in Tape & Reel (TR) packaging. PNP300JR-73-56R and KNP1WSJR-52-56R are supplied in Cut Tape (CT) packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Can these parts operate across the full -40°C ~ 200°C temperature range?

A: Yes. All three parts are rated for -40°C ~ 200°C operating temperature range.
