Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 12FR015 is determined by electrical and mechanical parameter equivalence. The substitute part 12FR015E maintains identical electrical specifications: 15 mOhm resistance, ±1% tolerance, 2-watt power rating, metal element composition, current sense and non-inductive features, ±50 ppm/°C temperature coefficient, and -55°C to 275°C operating range. Physical dimensions and axial package configuration remain unchanged. The primary distinction between the main part and substitute relates to packaging format (tape and reel versus bulk) and compliance certifications (RoHS status and REACH classification).

Parameter Comparison

Engineering Selection Recommendations

Both the 12FR015 and 12FR015E are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging format. The 12FR015E is RoHS compliant and carries an MSL rating of 1 (Unlimited), making it suitable for applications subject to RoHS directives or requiring documented moisture sensitivity classification. The 12FR015 remains available for applications without RoHS compliance mandates. Packaging format differs between the two parts: the 12FR015 is supplied in standard packaging, while the 12FR015E is supplied in bulk format. Both parts are suitable for direct substitution in current sensing circuits where the specified electrical parameters are required.

Frequently Asked Questions (FAQ)

Q: Can the 12FR015E be used as a direct replacement for the 12FR015?

A: Yes. The 12FR015E is electrically and mechanically equivalent to the 12FR015. Both parts share identical resistance values, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. Substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between the 12FR015 and 12FR015E?

A: The primary differences are packaging format and compliance certifications. The 12FR015E is RoHS compliant and carries an MSL rating of 1 (Unlimited), while the 12FR015 is RoHS non-compliant. The 12FR015E is supplied in bulk packaging, whereas the 12FR015 uses standard packaging.

Q: Which part should I select for RoHS-compliant applications?

A: The 12FR015E is RoHS compliant and is the appropriate selection for applications requiring RoHS compliance documentation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 12FR015 and 12FR015E have identical axial package dimensions of 0.094" diameter by 0.417" length (2.40 mm × 10.60 mm).

Q: What does MSL 1 (Unlimited) mean for the 12FR015E?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life under standard storage conditions and does not require special moisture control measures prior to soldering.
