Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RL0607-102-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 mH (exact match required)
• Core type: Ferrite drum core, unshielded
• Mounting configuration: Through-hole, radial vertical cylinder orientation
• Tolerance: ±10%

Secondary Compatibility Criteria:

• Current rating: Substitute must equal or exceed 205 mA
• DC resistance: Lower values are acceptable; higher values require circuit analysis
• Operating temperature: Substitute range must encompass or exceed -40°C to 125°C
• Saturation current: Higher values provide design margin

The RCH895NP-102K meets all primary matching criteria and exceeds secondary performance specifications, qualifying it as a direct substitute for the obsolete RL0607-102-R.

Parameter Comparison

Engineering Selection Recommendations

The RCH895NP-102K from Sumida America Components Inc. is qualified as a direct substitute for the obsolete RL0607-102-R based on the following engineering factors:

Functional Equivalence: Both components share identical inductance (1 mH), tolerance (±10%), core material (ferrite), shielding configuration (unshielded), and through-hole mounting orientation. The substitute meets or exceeds all electrical performance requirements with a higher current rating (220 mA vs. 205 mA) and significantly improved saturation current margin (300 mA vs. 150 mA).

Compliance Status: The RCH895NP-102K is an active production component with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The obsolete status of the RL0607-102-R necessitates transition to an actively manufactured alternative.

Physical Considerations: The substitute component has larger physical dimensions (0.307" diameter and 0.374" height versus 0.224" diameter and 0.287" height). PCB layout verification is required to confirm adequate clearance in the mounting area.

Temperature Range Limitation: The substitute operates to 100°C maximum versus 125°C for the original part. Applications requiring operation above 100°C require alternative component selection or thermal management review.

Frequently Asked Questions (FAQ)

Q: Can the RCH895NP-102K be used as a direct pin-for-pin replacement for the RL0607-102-R?

A: Yes, both components use identical through-hole radial vertical cylinder mounting with compatible lead spacing. However, physical dimensions differ; verify PCB layout clearance before implementation.

Q: What is the impact of the lower DC resistance in the RCH895NP-102K?

A: Lower DC resistance (1.84 Ohm vs. 4.76 Ohm) reduces resistive losses and heat generation in the inductor. This is a performance improvement for most applications. Circuit analysis is not required unless the original design specifically depended on the higher resistance value for current limiting or thermal characteristics.

Q: Does the substitute meet the same environmental specifications?

A: Both components have identical moisture sensitivity level (MSL 1 - Unlimited) and operate across -40°C to 100°C. The substitute's upper temperature limit is 25°C lower than the original. Applications operating above 100°C require alternative component selection.

Q: Are there any compliance or certification differences?

A: The RCH895NP-102K carries ROHS3 compliance certification. The original RL0607-102-R compliance status is not specified in available documentation. Both components share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What is the significance of the higher saturation current in the substitute?

A: The RCH895NP-102K saturation current of 300 mA versus 150 mA in the original part provides a 2x design margin. This indicates improved core material performance and reduces the risk of inductor saturation under transient current conditions.

Q: How should the larger physical size be evaluated?

A: The substitute is approximately 37% larger in diameter and 30% taller. Verify available PCB mounting area and clearance to adjacent components, connectors, and enclosure walls before design implementation.
