SL18 10005 Equivalent & Substitute Parts

Part Overview

The SL18 10005 is an inrush current limiter manufactured by Ametherm, rated at 10 Ohms ±20% with a maximum steady-state current of 5 A. The component features a 0.748" (19.00mm) diameter form factor and is actively produced. This part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain design continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for inrush current limiters is determined by the following critical parameters:

• Resistance value and tolerance (10 Ohms ±20%)
• Maximum steady-state current rating (5 A minimum)
• Physical form factor and lead spacing (mechanical fit in circuit board layouts)
• Compliance certifications (ROHS3, REACH)
• Product status (Active production)

The B57238S0100M000 qualifies as a substitute because it matches the core electrical specifications: 10 Ohms ±20% resistance, 5 A steady-state current rating, and ROHS3 compliance. The primary difference is the reduced diameter (0.630" vs 0.748"), which represents a more compact form factor. This dimensional change requires verification of mechanical fit within the target application's physical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and meet ROHS3 and REACH compliance requirements. The B57238S0100M000 carries UL approval, providing an additional certification advantage for applications requiring third-party validation. The electrical parameters are identical, ensuring functional equivalence in circuit operation. The dimensional reduction in the substitute part (19.00mm to 16.00mm diameter) necessitates physical layout verification to confirm compatibility with existing PCB footprints and mechanical mounting structures. Lead spacing remains within acceptable tolerance (7.80mm vs 7.50mm), presenting minimal impact on standard through-hole spacing.

Frequently Asked Questions (FAQ)

Q: Can the B57238S0100M000 be used as a direct replacement for the SL18 10005?

A: Electrical substitution is valid based on matching resistance, tolerance, and current ratings. Physical substitution requires confirmation that the reduced diameter (16.00mm vs 19.00mm) accommodates the application's mechanical constraints and PCB layout.

Q: What are the critical parameters for inrush current limiter substitution?

A: Resistance value and tolerance, maximum steady-state current rating, and compliance certifications (ROHS3, REACH) are the primary determinants. Physical form factor must be verified for mechanical compatibility.

Q: Does the B57238S0100M000 offer any advantages over the SL18 10005?

A: The B57238S0100M000 includes UL approval certification and features a more compact diameter, which may reduce PCB space requirements in applications where physical size is a design consideration.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The B57238S0100M000 carries additional UL approval, which may be required for specific application standards.

Q: What should be verified before implementing the B57238S0100M000 as a substitute?

A: Confirm that the 16.00mm diameter fits within the mechanical envelope of the target application. Verify lead spacing compatibility with existing PCB through-hole patterns. Validate that UL certification requirements align with application standards.
