Equivalent & Substitute Parts for 5629-RC

Part Overview

The Bourns 5629-RC is a 1 mH unshielded drum core wirewound inductor rated for 4.4 A with a maximum DC resistance of 183 mOhm. This through-hole radial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors. The 5629-RC carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5629-RC are identified based on matching the following critical parameters: inductance value (1 mH), tolerance (±10%), core material (ferrite), shielding type (unshielded), mounting method (through hole), and compliance certifications (ROHS3, REACH Unaffected).

Two substitute parts meet these criteria:

Direct Equivalent (1539M29): Matches all electrical specifications including current rating (4.4 A) and DC resistance (183 mOhm Max). Manufactured by Hammond Manufacturing with active product status. Identical package configuration (radial, vertical cylinder) and operating temperature range support direct substitution.

Functional Equivalent (1140-102K-RC): Matches inductance, tolerance, core material, shielding, and mounting type. Manufactured by Bourns Inc. with active product status. Differs in current rating (3.6 A vs. 4.4 A) and DC resistance (216 mOhm Max vs. 183 mOhm Max), suitable for applications with lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The Hammond Manufacturing 1539M29 provides full electrical and mechanical equivalence to the 5629-RC. Identical current rating, DC resistance, and package geometry ensure pin-compatible substitution. Active product status and ROHS3 compliance support long-term availability and regulatory compliance.

For Current-Limited Applications: The Bourns 1140-102K-RC serves applications where the 4.4 A rating exceeds circuit requirements. The reduced current rating (3.6 A) and increased DC resistance (216 mOhm) are acceptable trade-offs in lower-current designs. Active product status and ROHS3 compliance maintain regulatory alignment.

Compliance Considerations: Both substitute parts maintain ROHS3 and REACH Unaffected certifications, ensuring compatibility with environmental and regulatory requirements applicable to the original 5629-RC.

Frequently Asked Questions (FAQ)

Q: Can the 1539M29 replace the 5629-RC in all applications? A: Yes. The 1539M29 matches all critical electrical parameters (1 mH inductance, 4.4 A current rating, 183 mOhm DC resistance) and package configuration (radial, vertical cylinder). Pin compatibility and electrical performance are equivalent.

Q: When should the 1140-102K-RC be used instead of the 1539M29? A: The 1140-102K-RC is suitable for circuits where the maximum current requirement is 3.6 A or lower. The higher DC resistance (216 mOhm vs. 183 mOhm) may increase power dissipation in high-current applications, making it inappropriate for designs requiring the full 4.4 A rating.

Q: Are there physical mounting differences between these parts? A: The 1539M29 and 5629-RC share identical radial, vertical cylinder package geometry. The 1140-102K-RC uses a radial package with reduced height (1.030" vs. 1.500"), which may affect PCB layout compatibility in space-constrained designs.

Q: Do all substitute parts meet the same compliance standards? A: Yes. The 5629-RC, 1539M29, and 1140-102K-RC are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inductance tolerance for these parts? A: All three parts carry ±10% inductance tolerance at 1 kHz test frequency, ensuring consistent performance across the specified tolerance band.
