Substitute Part Grouping Explanation

Substitution eligibility for the CDH53-100LC is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 10 µH
• Inductance tolerance: ±15%
• Current rating: 1.23 A
• DC resistance: 160mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Physical dimensions: 6.00mm x 5.20mm x 3.20mm maximum height
• Package classification: Nonstandard

Environmental Parameters (Must Match):

• Operating temperature range: -40°C ~ 100°C
• Inductance test frequency: 1 kHz

The CDH53NP-100LC qualifies as a direct substitute based on complete alignment with all electrical, mechanical, and environmental specifications. The primary distinction is product status and packaging configuration, not functional performance.

Engineering Selection Recommendations

CDH53NP-100LC is the qualified substitute for CDH53-100LC based on the following engineering criteria:

Product Status Consideration: The CDH53-100LC carries obsolete product status, while CDH53NP-100LC is classified as active. Active product status ensures continued manufacturer support, availability, and compliance with current regulatory standards.

Regulatory Compliance: CDH53NP-100LC achieves ROHS3 compliance, whereas CDH53-100LC is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, CDH53NP-100LC is the appropriate selection.

Functional Equivalence: Both parts maintain identical electrical specifications across inductance, current rating, and DC resistance parameters. Both operate within the same temperature range and physical envelope, ensuring direct mechanical and electrical interchangeability in circuit designs.

Packaging Configuration: CDH53NP-100LC is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. CDH53-100LC is supplied in bulk packaging. Selection between these packaging formats depends on manufacturing process requirements and volume considerations.

Supply Chain Availability: CDH53NP-100LC demonstrates higher current inventory levels (5700 Pcs) compared to CDH53-100LC (4328 Pcs), supporting improved lead time performance and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can CDH53NP-100LC be used as a direct replacement for CDH53-100LC in existing circuit designs?

A: Yes. CDH53NP-100LC is electrically and mechanically equivalent to CDH53-100LC. Both components share identical inductance (10 µH), current rating (1.23 A), DC resistance (160mOhm maximum), core material (ferrite), and physical dimensions (6.00mm x 5.20mm x 3.20mm). No circuit redesign is required.

Q: What is the primary difference between these two part numbers?

A: The primary differences are product status and packaging format. CDH53-100LC is obsolete and supplied in bulk packaging. CDH53NP-100LC is active product and supplied in Tape & Reel (TR) packaging. Additionally, CDH53NP-100LC achieves ROHS3 compliance while CDH53-100LC is RoHS non-compliant.

Q: Are there any electrical performance differences between CDH53-100LC and CDH53NP-100LC?

A: No. Both parts are specified with identical electrical parameters: 10 µH inductance at ±15% tolerance, 1.23 A current rating, 160mOhm maximum DC resistance, ferrite core material, unshielded configuration, and -40°C to 100°C operating temperature range.

Q: Which part should be selected for new designs?

A: CDH53NP-100LC is the appropriate selection for new designs. This part carries active product status, ensuring long-term availability and manufacturer support. ROHS3 compliance also aligns with current regulatory requirements and customer specifications.

Q: Does packaging format affect component performance?

A: No. Tape & Reel (TR) packaging and bulk packaging do not affect electrical or mechanical performance. Packaging selection is determined by manufacturing process requirements. Tape & Reel format supports automated assembly, while bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both CDH53-100LC and CDH53NP-100LC operate across the identical temperature range of -40°C to 100°C, ensuring equivalent thermal performance in all specified applications.

Q: What is the significance of RoHS compliance in this substitution?

A: RoHS compliance restricts the use of hazardous substances in electrical and electronic equipment. CDH53NP-100LC achieves ROHS3 compliance, making it suitable for applications and markets requiring RoHS certification. CDH53-100LC, being RoHS non-compliant, may not meet customer or regulatory requirements in certain jurisdictions or applications.
