SCRH62B-100 Equivalent & Substitute Parts

Part Overview

The SCRH62B-100 is a 10 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 1.38 A continuous current with a maximum DC resistance of 150mOhm. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain the core electrical specifications while accommodating minor variations in physical dimensions and performance characteristics within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH62B-100 is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with tolerance range accommodating ±20% to ±25%
• Current Rating: Minimum 1.38 A continuous current capability
• DC Resistance: Maximum 150mOhm preferred; values up to 140mOhm are acceptable
• Shielding Configuration: Shielded construction required to maintain electromagnetic isolation
• Mounting Type: Surface mount package only
• Temperature Range: Minimum -40°C to 125°C operating window
• Compliance: ROHS3 compliance mandatory

Two substitute parts meet these criteria with documented equivalency:

B82462A4103M000 (EPCOS - TDK Electronics): Meets inductance and tolerance specifications. Current rating of 1.15 A falls below the primary requirement but saturation current of 1.8 A provides operational margin. Unshielded construction represents a functional deviation requiring circuit-level evaluation.

CDR6D28MNNP-100NC (Sumida America Components Inc.): Exceeds all primary electrical specifications with 1.8 A current rating and 88.8mOhm DC resistance. Maintains shielded construction and surface mount configuration. Operating temperature range of -40°C to 105°C is narrower than the original specification.

Parameter Comparison

Engineering Selection Recommendations

CDR6D28MNNP-100NC is the primary substitute for SCRH62B-100 applications. This part maintains shielded construction, exceeds current and saturation ratings, and delivers superior DC resistance performance. All compliance certifications align with the original specification. The narrower upper temperature limit of 105°C requires evaluation only in applications requiring sustained operation above this threshold.

B82462A4103M000 serves as a secondary alternative where shielding requirements can be relaxed or where circuit design accommodates the reduced continuous current rating of 1.15 A. The unshielded drum core construction may introduce electromagnetic coupling effects in sensitive analog or RF circuits. The extended upper temperature rating of 150°C provides advantage in high-temperature environments. Active product status ensures long-term availability.

Both substitutes are actively manufactured and maintain ROHS3 compliance, supporting regulatory and supply chain continuity objectives.

Frequently Asked Questions (FAQ)

Q: Can B82462A4103M000 be used as a direct replacement for SCRH62B-100?

A: B82462A4103M000 matches the 10 µH inductance and tolerance specifications. However, the continuous current rating of 1.15 A is below the original 1.38 A specification, and the unshielded construction differs from the shielded original. Application-specific evaluation is required to confirm suitability.

Q: What is the primary advantage of CDR6D28MNNP-100NC over the original SCRH62B-100?

A: CDR6D28MNNP-100NC provides higher current capacity (1.8 A vs. 1.38 A), lower DC resistance (88.8mOhm vs. 150mOhm), and maintains shielded construction. These characteristics deliver improved thermal performance and reduced power dissipation in the inductor element.

Q: Does the operating temperature range difference affect substitution suitability?

A: CDR6D28MNNP-100NC operates to 105°C maximum, compared to 125°C for the original. Applications requiring sustained operation above 105°C require thermal analysis or alternative selection. B82462A4103M000 extends to 150°C, providing margin for high-temperature environments.

Q: Are package dimensions compatible between substitute parts and the original?

A: All three parts are surface mount inductors with nonstandard packages. Physical dimensions vary slightly: SCRH62B-100 measures 6.50mm × 6.40mm × 3.20mm; B82462A4103M000 measures 6.00mm × 6.00mm × 3.00mm; CDR6D28MNNP-100NC measures 6.50mm × 6.50mm × 3.00mm. PCB layout verification is required to confirm fit within existing footprints.

Q: What compliance certifications apply to all substitute options?

A: All three parts maintain ROHS3 compliance and are classified as REACH Unaffected. Both active substitutes carry EAR99 export classification. B82462A4103M000 holds AEC-Q200 automotive qualification, providing additional reliability assurance for automotive applications.
