Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCH895NP-331K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 330 µH at 1 kHz test frequency
• Inductance tolerance: ±10%
• DC resistance: 610 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters:

• Package type: Radial, Vertical Cylinder (Open)
• Mounting type: Through Hole
• Physical dimensions: 0.307" diameter (7.80 mm) and 0.374" height (9.50 mm)

Compliance Parameters:

• RoHS3 compliance required

The substitute part RL895-331K-RC meets all these criteria. While the substitute exhibits a higher current rating (510 mA versus 390 mA), this represents an enhanced capability that does not compromise compatibility in applications designed for the original part's 390 mA specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RCH895NP-331K and RL895-331K-RC are active production components with ROHS3 compliance certification. Selection between these parts should be based on the following factors:

RCH895NP-331K Selection Criteria:

• Primary choice when Sumida America Components Inc. supply chain is preferred
• Specified current rating of 390 mA matches application requirements exactly
• Operating temperature range extends to -40°C, suitable for extended low-temperature environments
• Tape & Reel packaging for automated assembly processes

RL895-331K-RC Selection Criteria:

• Alternative when Bourns Inc. supply chain offers better availability or lead times
• Higher current rating (510 mA) provides additional margin in applications operating near the 390 mA specification
• Bulk packaging suitable for manual assembly or lower-volume production
• Operating temperature range of -30°C to 100°C adequate for standard industrial applications

Both parts are electrically and mechanically interchangeable within the specified parameters. Component selection should prioritize supply chain availability and procurement lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can RL895-331K-RC replace RCH895NP-331K in all applications?

A: Yes. Both inductors share identical inductance (330 µH), tolerance (±10%), DC resistance (610 mOhm max), core material (ferrite), shielding (unshielded), and physical dimensions (0.307" diameter, 0.374" height). The substitute's higher current rating (510 mA versus 390 mA) does not create incompatibility in circuits designed for the original part's 390 mA specification.

Q: What is the difference in packaging between these parts?

A: RCH895NP-331K is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. RL895-331K-RC is supplied in Bulk packaging, suitable for manual assembly or lower-volume applications. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there temperature range differences that affect substitution?

A: RCH895NP-331K operates from -40°C to 100°C, while RL895-331K-RC operates from -30°C to 100°C. For applications requiring operation below -30°C, the RCH895NP-331K is the required choice. For standard industrial temperature ranges (-30°C to 100°C), both parts are equivalent.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both RCH895NP-331K and RL895-331K-RC are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What determines whether a part can substitute for RCH895NP-331K?

A: Substitution requires equivalence in inductance value (330 µH), tolerance (±10%), DC resistance (610 mOhm max), core material (ferrite), shielding (unshielded), package type (radial vertical cylinder open), mounting type (through hole), and physical dimensions (0.307" diameter, 0.374" height). Current rating may exceed the original specification without affecting compatibility.
