RN214-1.2-02 Equivalent & Substitute Parts

Part Overview

The RN214-1.2-02 is a 10 mH common mode choke (CMC) designed for power line filtering applications. This through-hole component features a 1.2A current rating and is rated for 250V AC operation across a 2-line configuration. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN214-1.2-02 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 mH
• Current rating: 1.2A minimum
• Number of lines: 2-line configuration
• Mounting type: Through Hole
• Physical footprint: 23.00mm x 15.50mm (length x width)
• Package configuration: Vertical, 4 PC Pin

Secondary Compatibility Factors:

• DC resistance within acceptable operating range
• Voltage rating equal to or exceeding 250V AC
• Operating temperature range encompassing -40°C to 125°C
• RoHS and regulatory compliance status

Two substitute parts meet these criteria with varying degrees of parameter alignment:

RN214-1.2-02-10M (Schaffner EMC Inc.) — Direct manufacturer alternative with active product status, improved compliance certifications, and lower DCR.

CAV-1.2-10 (Amgis, LLC) — Cross-manufacturer substitute with identical mechanical footprint and electrical core specifications, though classified for signal line rather than power line filtering.

Parameter Comparison

Engineering Selection Recommendations

RN214-1.2-02-10M is the primary recommended substitute. This part is manufactured by the same supplier (Schaffner EMC Inc.), maintains active product status, and provides enhanced regulatory certifications (ENEC, UR, VDE). The DCR is marginally lower (195mOhm vs. 200mOhm), and the AC voltage rating is increased to 300V. The operating temperature range is reduced to -40°C ~ 100°C, which may require verification if the application demands the full 125°C upper limit of the original part.

CAV-1.2-10 serves as a secondary cross-manufacturer alternative when RN214-1.2-02-10M availability is constrained. This Amgis component matches the mechanical footprint and core electrical specifications (10 mH, 1.2A, 2-line configuration). However, the DCR is elevated to 285mOhm, representing a 42.5% increase over the original specification. Additionally, no AC voltage rating is specified, and the part is classified for signal line filtering rather than power line applications. The reduced height (15.50mm vs. 25.30mm) may affect PCB layout compatibility. Regulatory certifications are not listed.

Frequently Asked Questions (FAQ)

Q: Can RN214-1.2-02-10M be used as a direct replacement for RN214-1.2-02?

A: Yes. Both parts are manufactured by Schaffner EMC Inc., share identical mechanical dimensions and pin configuration, and maintain the same 10 mH inductance and 1.2A current rating. The primary consideration is the reduced operating temperature upper limit (100°C vs. 125°C) in the substitute part.

Q: What is the significance of the DCR difference between RN214-1.2-02 and CAV-1.2-10?

A: The CAV-1.2-10 exhibits 285mOhm DCR compared to 200mOhm in the original part. This 85mOhm increase will result in higher power dissipation and heat generation under load. For applications operating near the 1.2A current limit, this difference may be significant and requires thermal analysis.

Q: Why does CAV-1.2-10 have a lower height specification?

A: The CAV-1.2-10 height is listed as 15.50mm (matching its width dimension), whereas RN214-1.2-02 and RN214-1.2-02-10M are 25.30mm tall. This dimensional difference may affect PCB layout, clearance requirements, and component placement in space-constrained designs.

Q: Are there regulatory compliance differences between the substitutes?

A: RN214-1.2-02-10M carries ENEC, UR, and VDE certifications, exceeding the UR and VDE approvals of the original part. CAV-1.2-10 lists no approval agencies. For applications requiring specific regulatory compliance, RN214-1.2-02-10M is the appropriate choice.

Q: What is the difference between power line and signal line filter classifications?

A: The RN214-1.2-02 and RN214-1.2-02-10M are designated for power line filtering, while CAV-1.2-10 is classified for signal line filtering. This distinction reflects the intended application domain and may influence performance characteristics in specific circuit topologies.
