CDH53-101JC Equivalent & Substitute Parts

Part Overview

The CDH53-101JC is a 100 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc., rated for 370 mA with a maximum DC resistance of 1.57Ohm. This surface mount component operates across the temperature range of -40°C to 100°C and is currently classified as obsolete. Due to its obsolete status and limited availability, identifying equivalent substitute parts is essential for ongoing production support, design continuity, and component procurement strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDH53-101JC are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Matching Parameters:

• Inductance value: 100 µH (exact match required)
• Mounting type: Surface Mount (exact match required)
• Core configuration: Wirewound (exact match required)
• Shielding: Unshielded (exact match required)
• Current rating: Equal to or greater than 370 mA
• DC resistance: Equal to or less than 1.57Ohm
• Operating temperature range: Must encompass -40°C to 100°C minimum
• Physical footprint: Compatible with 6.00mm x 5.20mm x 3.20mm maximum envelope

Substitute parts are grouped into two categories: direct manufacturer equivalents from Sumida and cross-manufacturer alternatives that meet all electrical and mechanical specifications.

Engineering Selection Recommendations

CDH53NP-101JC (Sumida America Components Inc.):

This part is the primary substitute for the obsolete CDH53-101JC. It maintains identical electrical specifications (100 µH, ±5% tolerance, 370 mA, 1.57Ohm DCR) and physical dimensions (6.00mm x 5.20mm x 3.20mm). The CDH53NP-101JC is currently in active production status with 10,671 pieces in stock. It is ROHS3 compliant and available in Tape & Reel packaging, addressing both regulatory requirements and production logistics. This part is the recommended first choice for direct replacement applications.

PG0063.104NLT (Pulse Electronics):

This cross-manufacturer alternative meets the core electrical requirements with 100 µH inductance and exceeds the current rating specification (400 mA versus 370 mA requirement). The DC resistance is superior at 1.205Ohm maximum, providing lower losses. The operating temperature range extends to 130°C, offering broader thermal capability. However, the inductance tolerance is ±20% compared to the ±5% specification of the main part, and the physical footprint is slightly larger (6.20mm x 6.20mm x 2.50mm). This part is ROHS3 compliant and currently active in production with 921 pieces in stock. Selection of this part requires verification that the ±20% tolerance and modified dimensions are acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can CDH53NP-101JC be used as a direct replacement for CDH53-101JC?

A: Yes. The CDH53NP-101JC is a direct equivalent with identical electrical parameters (100 µH, ±5% tolerance, 370 mA, 1.57Ohm DCR) and physical dimensions. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel versus nonstandard). Both parts are manufactured by Sumida America Components Inc. and are suitable for direct substitution in existing designs.

Q: What are the key differences between CDH53NP-101JC and PG0063.104NLT?

A: Both parts share the same 100 µH inductance value and surface mount configuration. CDH53NP-101JC maintains the ±5% tolerance and 1.57Ohm DCR specification. PG0063.104NLT offers higher current rating (400 mA), lower DCR (1.205Ohm), and extended temperature range (-40°C to 130°C), but has ±20% inductance tolerance and a slightly larger footprint (6.20mm x 6.20mm versus 6.00mm x 5.20mm). Selection depends on tolerance and dimensional constraints of the application.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CDH53NP-101JC and PG0063.104NLT are ROHS3 compliant. The original CDH53-101JC is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part is acceptable.

Q: What is the impact of the ±20% tolerance on PG0063.104NLT?

A: The PG0063.104NLT has a wider inductance tolerance (±20%) compared to the CDH53-101JC and CDH53NP-101JC (±5%). This means the actual inductance value may vary between 80 µH and 120 µH. Applications requiring tight inductance control should use CDH53NP-101JC. Applications with broader tolerance requirements may accept PG0063.104NLT.

Q: Do the physical dimension differences affect PCB layout?

A: The CDH53NP-101JC maintains identical dimensions to the original part (6.00mm x 5.20mm x 3.20mm) and requires no PCB layout changes. The PG0063.104NLT has a slightly larger footprint (6.20mm x 6.20mm x 2.50mm). PCB designs must accommodate the larger length and width dimensions. The reduced height may provide clearance benefits in space-constrained applications.

Q: Which part should be selected for new production designs?

A: CDH53NP-101JC is the recommended choice for new production designs. It is actively manufactured, widely available (10,671 pieces in stock), maintains all original electrical specifications, and is ROHS3 compliant. PG0063.104NLT may be considered as a secondary option if the ±20% tolerance and modified footprint are acceptable and if the enhanced current rating or lower DCR provides design advantages.
