CMLB136T-470MS Equivalent & Substitute Parts

Part Overview

The CMLB136T-470MS is a 47 µH shielded inductor manufactured by Delta Electronics/Cyntec, rated for 4.5 A continuous current with a maximum DC resistance of 88 Ohm. This component is designed for surface mount applications in nonstandard package configurations and operates across the industrial temperature range of -55°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining compliance certifications and operational reliability across the intended application range.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the CMLB136T-470MS is based on the following critical parameters:

• Inductance Value: 47 µH with ±20% tolerance (37.6 µH to 56.4 µH acceptable range)
• Current Rating: Minimum 4.5 A continuous current capability
• Saturation Current: Minimum 5.2 A threshold
• DC Resistance: Maximum 88 Ohm at rated current
• Shielding: Shielded construction required
• Mounting: Surface mount configuration
• Compliance: RoHS3 and REACH requirements
• Temperature Range: Operating capability across -55°C to 125°C

The identified substitute PA4343.472NLT does not meet the inductance value requirement (4.7 µH versus 47 µH specified). This represents a 10-fold difference in inductance and falls outside the acceptable tolerance band. The substitute part operates in a different functional category and cannot be considered an equivalent replacement for this application.

Parameter Comparison

Engineering Selection Recommendations

Based on the parameter comparison, PA4343.472NLT cannot serve as a substitute for CMLB136T-470MS. The inductance value differential of 10:1 (4.7 µH versus 47 µH) represents a fundamental incompatibility that cannot be bridged through tolerance adjustments or application-level compensation.

Both components maintain Active product status and ROHS3 compliance. However, the inductance mismatch disqualifies the substitute from consideration regardless of its superior current handling capability or lower DC resistance characteristics.

For applications requiring the CMLB136T-470MS, direct procurement of the original part number is necessary. No equivalent substitute meeting all specified parameters has been identified in the provided dataset.

Frequently Asked Questions (FAQ)

Q: Can PA4343.472NLT be used in place of CMLB136T-470MS?

A: No. The PA4343.472NLT has an inductance value of 4.7 µH, which is 10 times lower than the required 47 µH. This fundamental difference in inductance value makes the parts incompatible for direct substitution.

Q: What is the primary reason these parts are not interchangeable?

A: Inductance value is the primary functional parameter for inductor selection. The CMLB136T-470MS is specified at 47 µH with ±20% tolerance (37.6 µH to 56.4 µH acceptable range). The PA4343.472NLT at 4.7 µH falls completely outside this range and serves a different circuit function.

Q: Are the physical packages compatible?

A: Both components use surface mount nonstandard packages with similar footprint dimensions (CMLB136T-470MS: 13.45mm × 12.60mm; PA4343.472NLT: 14.00mm × 12.80mm). However, package compatibility alone does not establish functional equivalence.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CMLB136T-470MS and PA4343.472NLT are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Compliance parity does not override the inductance value incompatibility.

Q: What should be done if CMLB136T-470MS inventory is unavailable?

A: Contact the manufacturer or authorized distributors for availability of the original part number. Alternative inductance values require circuit redesign and are not addressed through direct part substitution.
