Parameter Comparison

Engineering Selection Recommendations

The RN114-3-02-2M0 is the appropriate substitute for the obsolete RN114-3-02. Both components share identical electrical specifications (2 mH inductance, 3A current rating) and mechanical form factors (through-hole, 22.50mm x 21.50mm footprint). The substitute offers enhanced compliance certifications (ENEC, UR, VDE versus UR, VDE) and ROHS3 compliance status. The RN114-3-02-2M0 maintains active product status with significantly higher inventory availability (1732 pcs versus 747 pcs). The substitute exhibits lower DC resistance (52mOhm versus 55mOhm) and higher AC voltage rating (300V versus 250V), providing improved electrical performance margins. The operating temperature range of the substitute (-40°C to 100°C) is narrower than the original part; applications requiring operation above 100°C require design review.

Frequently Asked Questions (FAQ)

Q: Are the RN114-3-02 and RN114-3-02-2M0 pin-compatible?

A: Yes. Both components feature identical through-hole mounting with horizontal, 4 PC pin configuration and matching physical dimensions (22.50mm x 21.50mm x 14.60mm).

Q: What is the difference in DC resistance between these parts?

A: The RN114-3-02 specifies 55mOhm typical DCR, while the RN114-3-02-2M0 specifies 52mOhm typical DCR. This 3mOhm difference represents improved efficiency in the substitute variant.

Q: Does the substitute support the same voltage rating?

A: The substitute RN114-3-02-2M0 supports 300V AC, exceeding the original part's 250V AC rating. Applications designed for 250V AC operation are fully compatible.

Q: What is the temperature operating range difference?

A: The RN114-3-02 operates from -40°C to 125°C, while the RN114-3-02-2M0 operates from -40°C to 100°C. Applications requiring sustained operation above 100°C must evaluate thermal requirements against the substitute's specifications.

Q: Are both parts RoHS compliant?

A: Yes. The RN114-3-02 is RoHS Compliant, and the RN114-3-02-2M0 is ROHS3 Compliant, meeting current environmental standards.

Q: What packaging is available for the substitute?

A: The RN114-3-02-2M0 is supplied in tube packaging, compared to the original part's standard packaging configuration.
