SCRH105R-102 Equivalent & Substitute Parts

Part Overview

The SCRH105R-102 is a 1 mH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 450 mA continuous current with a maximum DC resistance of 1.99 Ohm and operates across the industrial temperature range of -40°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for standard commercial and industrial electronics applications.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting identical mechanical and environmental requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105R-102 is determined by strict equivalence across the following critical parameters:

Inductance value must equal 1 mH with tolerance of ±30%, matching the primary specification. Current rating must support minimum 450 mA continuous operation. DC resistance must not exceed 1.99 Ohm maximum to ensure equivalent power dissipation characteristics. Shielding configuration must remain shielded to maintain electromagnetic isolation properties. Operating temperature range must span -40°C to 125°C minimum. Mounting type must be Surface Mount with package dimensions of 10.50 mm × 10.30 mm length and width. RoHS3 compliance and MSL 1 rating are mandatory for regulatory and environmental compatibility.

The DR1050-102-R meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both SCRH105R-102 and DR1050-102-R maintain Active product status with full RoHS3 compliance and MSL 1 rating, confirming ongoing manufacturer support and regulatory alignment. The DR1050-102-R is manufactured by Eaton - Electronics Division using drum core wirewound construction with ferrite material, providing equivalent electrical performance within specified tolerances.

Selection between these parts should be based on availability, lead time, and cost considerations, as both components satisfy identical electrical and mechanical requirements for surface mount 1 mH shielded inductor applications.

Frequently Asked Questions (FAQ)

Q: Can DR1050-102-R replace SCRH105R-102 in existing designs?

A: Yes. Both components provide 1 mH inductance at ±30% tolerance, support 430+ mA continuous current, maintain shielded configuration, and operate across -40°C to 125°C. Package dimensions are equivalent within manufacturing tolerances (height difference of 0.10 mm is negligible for surface mount applications).

Q: What is the significance of the current rating difference (450 mA vs. 430 mA)?

A: The DR1050-102-R current rating of 430 mA remains within acceptable substitution parameters for applications designed around the SCRH105R-102 450 mA specification. Design margin assessment is required for applications operating near maximum current limits.

Q: Are there differences in core material between these inductors?

A: The SCRH105R-102 core material is not specified in available documentation. The DR1050-102-R uses ferrite drum core construction. Both achieve equivalent inductance and DC resistance specifications at the 100 kHz test frequency.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain Active product status with identical operating temperature ranges.

Q: Are there package footprint considerations for PCB layout?

A: Both parts use identical length and width dimensions (10.50 × 10.30 mm). Height difference is 0.10 mm (5.10 mm vs. 5.00 mm), which does not affect standard surface mount assembly or clearance requirements.
